JOURNAL FREE ACCESSThe purpose of this study was to investigate the postoperative one-year positional change following Intraoral Vertical Ramus Osteotomy (IVRO). Retrospective radiographic assessments were performed on 43 patients who underwent bilateral IVRO to setback without interosseous fixation.
The results were as follows:
1. No relationship was observed between the openbite and the mandibular displacement during postoperative treatment for one year. In addition, no relationship was observed between the amount of mandibular displacement following surgery and that during postoperative treatment for one year.
2. The postoperative mandibular position following IVRO was stable, and this method was effective to correct mandibular protrusion.View full abstractDownload PDF (897K) -

JOURNAL FREE ACCESSWe herein report on four patients with glossitis induced by vitamin B12 (VB12) deficiency. Of the four patients, who complained of glossal pain and who had on prior history of medical consultation (patient A, an 83-year-old female; patient B, an 81-year-old female; patient C, a 59-year-old female; patient D, a 68-year-old male), patients C and D had undergone gastrectomy. In patients A and B, anti-parietal cell antibody was elevated to>80, and atrophic gastritis was ascertained by endoscopic examination. Red blood cell counts were 336, 192, 382, and 358×104/μl, and hemoglobin levels were 12.6, 8.2, 12.8, and 12.7g/dl, in patients A, B, C, and D, respectively. Mean cell volume (MCV) increased to 106 to 128μ3 in three patients, although MCV only slightly elevated in patient C (103μ3). The levels of serum VB12 in patients A, B, C, and D were 48, 23, 8, and 110 pg/ml, respectively. With these findings, glossal pain thresholds and salivary flow rates (SFR) were largely decreased in all of the patients. The patients were treated with intravenous/oral VB12, and all of them except patient A were given oral iron (Fe). With treatment for about 3 weeks, glossal pain disappeared, and reformation of the glossal papillae was observed, in parallel with increases of serum VB12 levels. The improvement of the glossal condition was also supported by increases of pain thresholds and nonstimulated SFRs. These clinical findings indicate that VB12 deficiency may induce glossal pain as the first symptom, accompanying decreases of the glossal pain threshold, non-stimulated SFR, and the serum Fe level, and that estimation of the serum VB12 level and MCV is required for diagnosis of glossal pain, especially in patients with a history of total gastrectomy.View full abstractDownload PDF (1818K) -

JOURNAL FREE ACCESSWe clinico-statistically analyzed 13 patients with impacted supernumerary teeth in the lower premolar region, which patients we encountered who were found during the past six years. The incidence was approximately 0.09%. The occurrence in males was approximately twice that in females. All cases had a single impacted supernumerary tooth. More of the impacted supernumerary teeth were in the unilateral side than those in the bilateral side. Impacted supernumerary teeth were widely situated between the canine and the first molar, and all were located in lingual side. The tooth crown showed the regular premolar form in all cases. The roots of impacted supernumerary teeth were imcomplete in teenagers, whereas the roots were complete in persons over age 20. We estimated that the time of tooth germ formation of impacted supernumerary teeth in the lower premolar region was the same as that of the lower third molar.View full abstractDownload PDF (1591K) -

JOURNAL FREE ACCESSA case with taste disorder caused by a cerebellopontine angle tumor is described. A 69-year-old woman complained of hypogeusia, dry mouth, and abnormal oral sensation. She had a history of left-sided tinnitus and deafness, and she had had vertigo for the three years. Laterality of taste sensation in the tongue was detected by a taste test. We suspected a disorder of the facial nerve or the acoustic nerve. The diagnosis of a cerebellopontine angle tumor was made by MRI.View full abstractDownload PDF (2162K) -

JOURNAL FREE ACCESSLenz microphthalmia syndrome was first discribed by Lenz in 1955 as disorders consisting of (1) microphthalmia, (2) skeletal anomalies of the hands and clavicles, (3) renal anomalies, (4) genital anomalies, and (5) anodontia. We could find only 30 cases in a Medline search covering the last 45 years.
The patient was a 2-month-old boy. Microphthalmia, coloboma of the optic nerve, bilateral hydronephrosis, barrel chest, bilateral uveitis, hypospadias, cryptorchism, and cleft lip and palate were observed, and he was diagnosed as having Lenz microphthalmia syndrome. At a later examination, he was found to have panhypopituitarism.
We used a Hotz's plate to improve feeding. At one year of age, cheiloplasty (modified Millard's method) was performed, and at one year and four months, he received a palatoplasty (Furlow's method). Because of panhypopituitarism, we admitted steroid under the anesthesia and performed strict management of the infusion solution after the operations. He was discharged from the hospital without post-operative difficulties. At present he is three years and four months old and is under careful follow-up.View full abstractDownload PDF (2229K) -

JOURNAL FREE ACCESSIn this study, we carried out a clinical study of four auricular prosthesis using craniofacial implants (Branemark system®). The following results were obtained. Patients were 4 males of ages 25, 21, 35, and 46, respectively. Their primary diseases were caused by auricular malformation, burn injury and traffic accident. The fixtures (length of 3 mm or 4 mm) were installed in the temporal bone, and in all (total 10 heads), effective ability was obtained. The epithesis was supported by a bar-type support device, making it easy for the patient attach or detach it by himself or herself. No serious problems were observed in the skin or bone tissue surrounding the implant, and satisfactory results were obtained in the cosmetic aspect and support of epitheses.View full abstractDownload PDF (3522K) -

JOURNAL FREE ACCESSWe analyzed the development of the trigeminal neural circuit in embryonic brainstem in relation to respiration. The brainstems were removed from rat embryos and neonates. The respiratory activities in the trigeminal nerve were analyzed. Trigeminal respiratory activities could be recorded in embryonic rat brainstem of E 16 (16 embryonic days) and older. The cyclic time of respiration was 107±24.81 sec at E17. At E19, it became shorter (34.63±6.11 sec). The application of an NMDA receptor agonist made the cyclic time shorter. At E19, the cyclic time of trigeminal respiratory activities was 16.14±2.79 sec (NMDA 2μM), 14.57±3.36 sec (NMDA 5μM), at E17 69.50±11.90 sec (NMDA 5μM) and 20.225±4.84 sec (NMDA 10μM).
It is likely that the trigeminal respiratory circuit becomes organized at E16, and that NMDA receptor is involved in the circuit.View full abstractDownload PDF (534K)
