In this report, we show a case of the extensive nasopalatine duct cyst showing remarkable nasolabial protrusion. CT and MR examinations showed remarkable expansion of the extraosseous part of the lesion toward anterior and lateral sides, and this finding is considered to show the rather aggressive nature of this common cystic lesion after penetration of the maxillary cortex.

Maxillary distraction osteogenesis using intraoral distractors is now one of the standard treatments of maxillary retrusion. This report shows 2 cases of breakage of this internal maxillary distractor in patients with cleft lip and palate; one was observed during the distraction period and the other was during the retention period. The first case required a rotational movement of the distraction segment, and this movement caused the laterally dislocation of the posterior part of the distractor, where the distractor suffered some mechanical forces by mouth opening. In the latter case, breakage of distractor was observed on the radiographs taken 3 months after distraction and this complication may have been caused by mechanical force by occlusion and mastication. Both breakages were found at the joint of the anchorage plate and the extension rod, which has some flexibility for adjusting the plate to the bone surface. Therefore, surgeons should pay special attention for this mechanical weak area in this distractor not only during the advancement period, but also during the retention period and should avoid unnecessary frequent bending for adopting the bone surface, which directly weakens the joint.

Purpose: To evaluate the incidence of blood exposure during outpatient oral surgery from splattering caused by use of high-speed rotary instruments at the Referral and Teaching Center, University Dental Hospital.
Materials and Methods: Twenty-five consecutive patients who had impacted mandibular third molars were selected. The attending surgeon wore an operation gown and visor mask, and carried out the tooth extraction with the regular procedure. We counted the number of bloodstains found on the operation gown and visor mask, and confirmed the presence of diluted and invisible bloodstains using a leucomalachite green presumptive test, which was able to detect dilutions up to 1:4,000.
Results: There were 469 separate bloodstains on the gown and visor mask of oral surgeons, which came from 19 (76%) of 25 patients during impacted mandibular third molar surgery. Presumptive tests for invisible bloodstains resulted in 1,206 positive reactions, 2.57-fold greater than the visible stains, from 88% of the cases. All of the surgeons were right-handed and the common areas of staining were the right forearm, face, and thorax regions.
Conclusions: Dental procedures with high-speed instruments exposed surgeons to possible blood-borne infections by splashing in nearly 90% of the cases. Greater than 50% of the stains were invisible to the naked eye. Based on our results, strict compliance with barrier precautions, including routine use of an operation gown and visor mask, is recommended whenever oral surgery is carried out with high-speed rotary instruments.

Objective: Surgical-assisted rapid palatal expansion includes various treatment procedures for solving transverse maxillary deficiencies, especially in cases with a matured palatal suture. Recent introduction of the concept of distraction osteogenesis has contributed to generalize this useful treatment and to develop some bone-borne devices that will not cause the problems found in cases treated by tooth-supported palatal expander. This report shows a conventional bone-borne distractor using commercially available orthodontic palatal expansion screws. Method: The distractor consists of 2 parts: one is a commercially available orthodontic palatal expansion screw (Hyrax type, Fan style) and another is a screw-ring, which is one of the attached parts of the mandibular distraction system. The bone screws are inserted transmucosally to the palatal bone via the screw-rings. Result: The palatal distractor can be applied to varied palatal shapes and can expand the palate without any trouble. Conclusion: This conventional palatal distractor may contribute to generalize the transpalatal maxillary distraction osteogenesis for cases with maxillary teeth problems. © 2008 Mosby, Inc.

In this study, we found that a certain motor branch of glossopharyngeal (IX) motor nerves stably exhibits not only inspiratory activity but also expiratory activity with pons removal in neonatal rat brainstem-spinal cord preparations in vitro. Because this finding indicates that IX expiratory activity is masked by an inhibitory mechanism operating in the pons, we sought to determine the candidate neurons that exert an inhibitory effect on IX expiratory activity. IX expiratory activity was observed when only the pons was perfused with noradrenaline (NA) or clonidine (alpha 2 adrenergic receptor agonist), but not when NA and yohimbine (alpha 2 adrenergic receptor antagonist) were perfused together. IX expiratory activity was also observed following the removal of the dorsal pons but not the ventral pons. The local administration of clonidine into the bilateral locus coeruleus (LC) evoked burst discharges during the expiratory phase in the IX motor rootlet. These results suggest that neurons in the LC that possess an a2 adrenergic receptor on the membrane surface exert a tonic inhibitory effect on IX expiratory activity in neonatal rat brainstem-spinal cord preparations.

BACKGROUND AND PURPOSE: The presence of cervical lymph node metastases is an important prognostic factor for oral tongue cancer. The accurate preoperative assessment is essential for treatment. Several studies have suggested that histologic tumor thickness is related to the metastases. The aim of this study was to determine whether MR images of oral tongue tumor have the potential to predict cervical lymph node metastases.
MATERIALS AND METHODS: A total of 43 patients with squamous cell carcinoma of the oral tongue were investigated. Tumor thickness, sublingual distance between tumor and sublingual space, and paralingual distance between tumor and paralingual space, as determined from coronal MR imaging, were preoperatively estimated. Logistic regression analysis was used to identify independent predictors of lymph node metastases.
RESULTS: Univariate logistic regression analysis showed that T classification, N classification, and 3 measured MR imaging distances (millimeters) were significantly associated with lymph node metastases. Multivariate logistic regression analysis showed that tumor thickness (odds ratio, 1.34; 95% confidence interval [CI], 1.11-1.63; P <.005) and paralingual distance (odds ratio, 0.53; 95% Cl, 0.35-0.82; P <.005) were significant predictors for lymph node metastases. The probability of metastases was estimated with these models. The preoperative decision (20% probability) as to whether to perform neck dissection could be based on tumor thickness of >9.7 mm and paralingual distance of <5.2 mm.
CONCLUSION: MR images provide satisfactory accuracy for the preoperative estimation of the tumor thickness and the paralingual distance, which are valuable for predicting cervical lymph node metastases.

Congenital granular cell lesion (CGCL) is well known to appear as the congenital epulis, predominantly on the median maxillary alveolar ridge. This lesion rarely occurs on the tongue, and only 7 cases, including 4 cases with simultaneous occurrence on the alveolar ridge, have been reported in the English literature. In this report, we report a case of congenital granular cell lesion seen on the tongue. The patient was a 7-day-old Japanese girl who presented with a polypoid mass on the anterior ventral surface near the tip of the tongue. The lesion was excised at 4 months, and its histological examination revealed large granular cells. Immunochemical staining by S- 100 was negative, and it was diagnosed as congenital granular cell lesion.

Leiomyomatous hamartoma (LH) is congenital lesion rarely seen in oral cavity. In English literature, all reported cases appeared as solitary lesion in alveolar ridge or the tongue, and there have never been a report showing a case of multiple occurrence of this lesion. A quite rare case of multiple LH occurred in a 2-year-old Japanese boy is presented. A polypoid lesion was presented at incisive papilla and two isolated lesions in the tongue dorsum, one appeared as a polypoid mass in the posterior dorsum and other as a small spindle-shaped agger in the anterior dorsum. All of them were histologically diagnosed as LH.

Ossifying fibroma and fibrous dysplasia of the jaw are maxillofacial fibro-osseous lesions that should be distinguished each other by a pathologist because they show distinct patterns of disease progression. However, both lesions often show similar histological and radiological features, making distinction between the two a diagnostic dilemma. In this study, we performed immunological and molecular analyses of five ossifying fibromas, four cases of extragnathic fibrous dysplasia, and five cases of gnathic fibrous dysplasia with typical histological and radiographic features. First, we examined the difference between fibrous dysplasia and ossifying fibroma in the expression of Runx2 (which determined osteogenic differentiation from mesenchymal stem cells) and other osteogenic markers. Fibroblastic cells in fibrous dysplasia and ossifying fibroma showed strong Runx2 expression in the nucleus. The bone matrices of both lesions showed similar expression patterns for all markers tested except for osteocalcin. Immunoreactivity for osteocalcin was strong throughout calcified regions in fibrous dysplasia, but weak in ossifying fibroma lesions. Second, we performed PCR analysis with peptide nucleic acid (PNA) for mutations at the Arg(201) codon of the alpha subunit of the stimulatory G protein gene (GNAS), which has reported to be a marker for extragnathic fibrous dysplasia. All nine cases of extragnathic or gnathic fibrous dysplasia were positive for this mutation. On the other hand, none of the five cases of ossifying fibroma showed the mutation. These findings indicate that although fibrous dysplasia and ossifying fibroma are similar disease entities, especially in the demonstration of the osteogenic lineage in stromal fibroblast-like cells, they show distinct differences that can be revealed by immunohistochemical detection of osteocalcin expression. Furthermore, PCR analysis with PNA for GNAS mutations at the Arg(201) codon is a useful method to differentiate between fibrous dysplasia and ossifying fibroma.

Because the submandibular gland is believed to have no intraparenchymal lymph nodes, preserving the submandibular gland for neck dissection and transferring the submandibular gland in order to prevent xerostomia induced by radiation therapy in patients with head and neck cancer have recently been described. We report a case of intraparenchymal metastasis in the submandibular gland 8 months after the initial intraoral excision of tongue cancer. This finding offers evidence that the submandibular gland includes intraparenchymal metastasis that can be involved with cancer. © 2006 Elsevier Ltd. All rights reserved.

Background: The frequent insertion of self-tapping screws for securing the proximal positioning plate in bimaxillary osteotomy often cause loosening of screws and plate, which produces incorrect repositioning. In this article, a newly developed base-attachment for a T-shaped proximal positioning plate for bimaxillary osteotomy is presented. Material: The base-attachment set consists of a titanium base-attachment and two titanium tapped screws. The attachment has a shallow depression having the same shape as the basal part of the positioning plate. Method: The base-attachment is secured by self-tapping screws until the end of the procedure, and the T-shaped proximal positioning plate is placed and secured by two titanium-tapped screws. Result: By using this base-attachment, the T-shaped plate can be easily placed repeatedly without difficulty. Conclusion: This base-attachment set may be useful for the frequently repositioned proximal plate in bimaxillary osteotomy. (C) 2006 European Association for Cranio-Maxillofacial Surgery.

The cortical masticatory area (CMA) elicits rhythmic jaw movements in response to repetitive stimulation and is involved in the control of mastication. Based on jaw movement patterns, the CMA is divided into two parts. One is the part of the CMA in which a T-pattern similar to jaw movements during food transport in natural mastication is evoked by electrical stimulation. The other is more dorsomedially located, and during chewing a C-pattern similar to jaw movements can be induced. However, it is still not known which region of the putamen receives projections from the CMA and whether projections originate from both parts of the CMA. In this study, electrophysiological and histological experiments were undertaken in rabbits to investigate projections from the CMA to the putamen. Both experiments showed that the ventral region of the putamen received projections from the CMA. The density of the projections from the CMA area inducing the T-pattern seemed to be higher than that from the area inducing the C-pattern. Furthermore, the peak latency of the evoked potentials from stimulation of the CMA area inducing the T-pattern was shorter than that from stimulation of the area inducing the C-pattern. The data obtained from the present study indicate the functional role of the ventral region of the putamen in the regulation of mastication, and further suggest that the corticostriatal pathway is involved in the transition between behavioral jaw movement patterns. © Springer-Verlag 2004.

A maxillofacial simulator can support education and training. In the present study, cutting, separation, and quantitative rearrangement of bone during orthognathic surgery were simulated by means of a haptic device with virtual tactile perception. Computed tomographic (CT) images of two patients with severe jaw deformity, one women and one man, were input into the device. In the woman, Le Fort I osteotomy of the maxilla and sagittal splitting ramus osteotomy of the mandible were initially simulated. During surgery with the haptic device, separation and rearrangement of the maxilla and the ramus of the mandible were initially processed. However, there was discrepancy and overlapping of the ramus with the mandible. Intraoral vertical osteotomy of the right ramus was then performed, with satisfactory results and less discrepancy and interference. The simulation was referred to at surgery, and satisfactory surgical assistance was postoperatively confirmed on CT images. The male patient had severe jaw deformity due to unequal growth between the ramuses, resulting in anterior crossbite. Sagittal splitting ramus osteotomy with rotation of the mandible was successfully simulated. Because of its versatility and functions, the present device was found to be useful for simulating various procedures for orthognathic surgery and thereby three-dimensionally determine surgical movements.

A maxillofacial simulator can support education and training. In the present study, cutting, separation, and quantitative rearrangement of bone during orthognathic surgery were simulated by means of a haptic device with virtual tactile perception. Computed tomographic (CT) images of two patients with severe jaw deformity, one women and one man, were input into the device. In the woman, Le Fort I osteotomy of the maxilla and sagittal splitting ramus osteotomy of the mandible were initially simulated. During surgery with the haptic device, separation and rearrangement of the maxilla and the ramus of the mandible were initially processed. However, there was discrepancy and overlapping of the ramus with the mandible. Intraoral vertical osteotomy of the right ramus was then performed, with satisfactory results and less discrepancy and interference. The simulation was referred to at surgery, and satisfactory surgical assistance was postoperatively confirmed on CT images. The male patient had severe jaw deformity due to unequal growth between the ramuses, resulting in anterior crossbite. Sagittal splitting ramus osteotomy with rotation of the mandible was successfully simulated. Because of its versatility and functions, the present device was found to be useful for simulating various procedures for orthognathic surgery and thereby three-dimensionally determine surgical movements.

Background: Several studies have shown an increased risk of mandibular angle fractures by the presence of the lower third molar (M3), especially the incompletely erupted M3. The presence of M3s might influence condylar fractures, which is one of the most common fracture sites, as well as the angle fracture. Methods: Six hundred ninety-two mandibular sides among 346 patients with mandibular fracture were analyzed. They were classified into two groups according to the presence of incompletely erupted M3s and were analyzed according to fracture site, age, and cause of injury. Results: Among these patients with mandibular fractures, the frequency of occurrence of the mandibular angle fracture was higher in the group with incompletely erupted M3s (p &lt
0.0001) and that of the condylar fracture was higher in the group without it (p &lt
0.001). Conclusion: The result of this retrospective investigation shows that an incompletely erupted M3 decreases the risk of condylar fractures and increases the risk of mandibular angle fractures.

Osteochondroma is a benign neoplasm that usually develops in long. bones and very rarely occurs in craniofacial bones. Nearly all reported mandibular osteochondromas have arisen in the condyle and the coronoid process, and occurrence in other locations is extremely rare. We describe a case of osteochondroma arising from the inferior border of the mandibular symphysis.

Objective. The aim of this study was to investigate the incidence and type of maxillofacial fractures caused by various sports played with a ball to better understand the nature of these fractures.
Study design. Retrospective study was carried out using records from 100 patients treated between 1986-2002. Age and sex, etiology, and site of the fracture, yearly and monthly distribution of the fractures, and treatment modality were analyzed.
Results. The fractures mostly resulted from baseball (44%), followed by rugby (28%) and soccer (18%). The highest incidence was in the 10- to 19-year age-group with male propensity. The most common cause of the fractures was impact against another player (43%). The majority of the patients suffered from mandibular fractures (56%), followed by midface (31%) and alveolar fractures (12%). Mandibular angle, zygoma, and zygomatic arch fractures were prominent for rugby fractures. A yearly comparison of the fracture incidence showed a gradual decrease over the 16-year period. Fractures had a peak incidence in autumn. 55% of the patients were treated surgically. Surgical intervention was mostly needed for patients sustaining fractures during soccer (72.2%).
Conclusions. Among ball-related sports, baseball is responsible for most of the maxillofacial fractures, but, although the incidence is not that high, soccer-related fractures may be more severe due to the nature of this sport.

Objective: This study was performed to clarify the characteristics of facial fractures caused by falls with a particular focus on aetiology. Patients: Of 505 patients with facial fractures treated in the Department of Oral and Maxillofacial/Craniofacial Surgery, Heidelberg University Hospital from January 1997 to May 2001, 129 patients injured by falls were analysed. Study design: Aetiological analysis was performed according to falling patterns. Results: The distribution of age showed two peaks in the 4th and 8th decades, and the male to female ratio was 1.1:1, unlike the overall facial fracture ratio of 3:1. Seventy-six patients had fallen from standing height or less and 44 patients had fallen from greater heights. The former cases were more often seen in older females. More severe injuries tend to be seen in the patients who have fallen from greater heights, and in the cases associated with acute medical disorders. Conclusion: This retrospective study documents the higher risk of fractures in older females and the higher risk of severe injury in those patients who were unconscious. This is in agreement with recent orthopaedic studies. (C) 2003 European Association for Cranio-Maxillofacial Surgery.

To correct the nasal deformity in cleft lip patients, a new procedure of open rhinoplasty using a "flying-bird" incision in the nostril tip with a vestibule "tornado" shaped incision in the cleft side is presented. The newly designed vestibular incision produces effective vestibular advancement with the freed lower lateral cartilage. The flying-bird incision makes it possible to produce a suitable nostril tip appearance with symmetrical external nostril vestibules. If the vestibular defect after flap advancement is wide, a full-thickness skin graft is used to give priority for making a good external nostril shape. This procedure is useful for most cleft lip noses, particularly in cases of moderate to severe deformity.

To clarify the aspects and role of oropharyngeal closure, soft palate movements during sucking were observed and then assessed by electromyographic and fluoroscopic analyses. Three patterns of sucking movements by the palatoglossus and levator veli palatini muscles were analyzed with electromyographic means in seven healthy adults. Furthermore, a forced sucking maneuver, which required special effort to produce a strong sucking pressure by opening the jaw, was analyzed using lateral fluoroscopy in three of the subjects. During all tested sucking movements, the palatoglossus muscle showed continuous activity. The levator veli palatini muscle did not show remarkable activity during regular air sucking or water sucking when water was held in the oral cavity. However, its participation increased when intraoral sucking pressure was increased by opening the jaw, and lateral fluoroscopic examinations revealed that the soft palate was pulled toward the oral cavity to form a tight contact between the rostral portion of the soft palate and the retrotongue, causing the soft palate to make an "L" shape. The palatoglossus muscle plays a major role in palatal movement during sucking. Furthermore, the levator veli palatini muscle, whose activity was observed only during high-pressure sucking with an open jaw, may act to maintain tension in the soft palate against strong negative pressure in the oral cavity.

Objective: Paediatric maxillofacial fractures are not common and carry different clinical features when compared with adults. To clarify the differences of aetiology and patterns of fractures in paediatric patients, a clinical retrospective analysis was performed. Patients: One hundred seventy-four paediatric patients younger than 16 years of age treated in the First Department of Oral and Maxillofacial Surgery, Osaka University Dental Hospital during a 15-year period were analysed. Study design: Age, sex, fracture patterns, incidence, common locations of the mandibular fractures and treatment were studied according to the patients' charts and radiographs. Results: The ratio of boys to girls was 2: 1 and the largest age subgroup was 15-years old. The most common cause of injury was bicycle accidents (26%), followed by falls (25%). The distribution of causes and ages revealed that the incidence of the fall-related injuries decreased in patients older than 10 years, and assaults became a common cause in patients older than 12 years. The yearly distribution showed a decrease of the group between 6 and 10 years and of bicycle-related accidents in the last 5-year period (1992-1996). Mandibular fractures were most common (56%), followed by fractures of the alveolar process (31%). Condylar fracture was common in children younger than 14 years, especially in those below 6 years. Fractures of the mandibular angle were the most common in those above 13 years. Conclusion: These results document that the aetiological characters and patterns of paediatric maxillofacial fractures gradually shifted towards those found in adolescents.

This study showed the influence of the push-back operation on the occurrence of sleep-related apnea in cleft-palate patients with an analysis of arterial oxygen saturation (SpO(2)) during sleep, polygraphic analysis of nasal air flow, and chest wall movements. The postoperative SpO(2) was lower than that of the presurgical period in all cases, requiring from five to nine days to recover to presurgical levels. According to polygraphic analysis this depression of SpO(2) was caused by peripheral obstructive apnea, while, in spite of the cessation of nasal airflow, chest wall movement continued.
