The clinical research of peripheral facial nerve paralysis during the last 10 years has been carried out with 39 cases in our clinic. of these, 6 cases of facial nerve paralysis after dental procedures were reported in this paper.We analysed the relationship between peripheral facial nerve paralysis and dental procedures with special reference to etiology, speed of onset, recovery, etc.

This study aimed to compare cephalometric changes in the upper airway morphology, including the hyoid bone position, after the conventional Le Fort I (LF) osteotomy, and an LF and horse-shoe osteotomies. Twenty-two patients diagnosed as having skeletal maxillary protrusion at the Department of Oral and Maxillofacial Surgery/Orthodontics, Yokohama City University Medical Center, were included. They were divided into two groups as follows: 13 patients underwent LF and sagittal split ramus osteotomies (LF group); and 9 patients underwent LF, horse-shoe and sagittal split ramus osteotomies (HS group). The following linear variables were measured on lateral cephalometric radiographs taken before (T0), immediately after (T1), and 1 year after (T2) surgery: palatal pharyngeal space (PPS), the length from the posterior pharyngeal wall to the posterior nasal spine (PNS); superior posterior palatal space (SPPS), the length from the posterior pharyngeal wall to the middle point between the PNS and the lowest point of the soft palate; middle posterior palatal space (MPS), the length from the posterior pharyngeal wall to the lowest point of the soft palate; inferior posterior palatal space (IPS), the length from the posterior pharyngeal wall to the tongue passing the lowest point of the second cervical vertebra; epiglottic pharyngeal space (EPS), the length from the posterior pharyngeal wall to the tongue passing the front end of the epiglottis; S-H, the length from the lowest point of the hyoid bone to the Sella; and C3-H, the length from the lowest point of the hyoid bone to the lowest front point of the second cervical vertebra. Statistical analyses were performed using the Mann-Whitney U test. P values of <0.05 indicated statistical significance. SPPS and MPS decreased at T2 in the HS group. IPS and EPS increased at T1 in both groups but decreased at T2 in the HS group. S-H decreased at T1 in both groups and at T2 in the LF group. C3-H increased at T1 in both groups but decreased at T2 in the HS group. The anteroposterior diameter of the oropharynx was unchanged in the LF group because the tongue moved upward after the palate moved upward but changed in the HS group because the tongue moved backward and the oral volume decreased due to the absence of palatal segment movement. In conclusion, the anteroposterior diameter of the oropharynx decreased after backward and upward movements of the maxilla by LF and HS in the patients with skeletal maxillary protrusions.

In subjects with facial asymmetry, it is generally accepted that the maxillary frontal occlusal plane inclines toward the deviated side of the mandible. However, a few patients with facial asymmetry have their frontal occlusal planes inclined toward the contralateral side of the mandibular deviation. The aim of this study was to elucidate the morphological features of the subjects with mandibular deviation with the frontal occlusal planes inclined toward the contralateral side.The sample consisted of 40 patients whose Menton was deviated at least 2.0 mm from the facial midline. They were divided into two groups based on the relationship between the side of inclination of the frontal occlusal plane and the side of the mandibular deviation. Group IL consisted of 20 patients whose frontal occlusal plane inclined to the ipsilateral side of the mandibular deviation, while Group CL consisted of 20 patients whose frontal occlusal plane inclined to the contralateral side of the mandibular deviation. Then, we compared the two groups using 1) lateral cephalometric analysis, 2) P-A cephalometric analysis, 3) frontal soft tissue analysis and 4) dental casts analysis. The following findings were obtained:1. In Group CL patients, not only the frontal occlusal plane defined by bilateral molar positions, but also the maxilla itself significantly inclined toward the contralateral side of the mandibular deviation.2. In Group CL patients, the maxillary dental midline was significantly deviated toward the contralateral side of the mandibular deviation.3. The difference in bilateral mandibular ramus lengths was significantly smaller in Group CL patients.4. In Group CL patients, the mandibular molar compensation for the mandibular lateral deviation was significantly less than that in Group IL patients.5. In Group CL patients, both the midline and cant of the upper lip were significantly deviated toward the contralateral side of the mandibular deviation.6. The incidence of missing or buccolingual version of maxillary premolar teeth was significantly higher in Group CL patients.

Although varicella zoster virus (VZV) infection commonly occurs in the oral and maxillofacial region, tooth exfoliation and alveolar osteonecrosis are relatively rare complications. We describe two cases of tooth exfoliation and alveolar osteonecrosis caused by VZV infection of the trigeminal nerve and review the literature. A 66-year-old man and a 38-year-old man were referred to our hospital because of tooth exfoliation. The first patient had a history of spinocerebellar degeneration, and the second had a history of chronic myelogenous leukemia. Tooth exfoliation occurred on day 21 and day 25 after the onset of VZV infection, respectively. Clinicopathological examination in the first patient revealed actinomyces infection. Panorama x-ray films obtained previously in the second patient revealed no evidence of severe periodontal disease before VZV infection. These findings suggested that tooth exfoliation and osteonecrosis by VZV infection were not only caused by existing severe dental infectious disease, but also by various factors such as multiple oral bacteria, tissue reaction to VZV infection, and compromised status.

Color Doppler imaging findings were reviewed for 36 lymph nodes in 13 patients with oral cancer who underwent neck dissection. Seventeen lymph nodes were histologically diagnosed as metastatic and 19 as non-metastatic. Color flow was observed in 6 nodes, all of which were non-metastatic. None of the 17 metastatic lymph nodes had color flow. Al-though 13 of the 19 non-metastatic lymph nodes also had no detectable color flow, all of these nodes were less than 10mm in diameter.<BR>These results suggest that normal or inflammatory swollen lymph nodes have color flow detectable with color Doppler imaging, and that metastasis to these nodes leads to the loss of color flow. We conclude that color Doppler imaging facilitates the diagnosis of cervical lymph node matastasis.
