ジャーナル フリーTo establish a more accurate and safer method for the design of free rectus abdominis myocutaneous flaps, we analyzed the vascular anatomy from the origin of the deep inferior epigastric artery to the skin in 36 fixed Japanese adult cadavers and 6 unfixed fresh cadavers. As for the vascular arrangement from the origin of the deep inferior epigastric artery to the superior epigastric artery, a single-type pattern showing ascension of one vessel was most frequently observed (66%), followed by a multiple-type pattern showing ascension of two vessels (33%). The mean vascular intersegmental distance at the site corresponding to the vascular pedicle of the deep inferior epigastric artery was 118.8±36.4mm. The mean internal diameter of the deep inferior epigastric artery in the inquinal ligament area was 1.87±0.4mm. The deep inferior epigastric artery entered the posterior surface of the rectus abdominis on its medial side or mid-area lateral to the navel in 92% of the cadavers. Branches passed the navel in 100%of the cadavers. The subdermal plexus was distributed from the navel to two-thirds of the height of the xiphoid process in the superior direction, to the anterior axillary line in the lateral direction, and to the area corresponding to the inguinal ligament in the inferior direction. These vessels were arranged in a cephalocaudal direction in the median anterior abdominal wall but ran in the direction of the surrounding arteries, i. e., the lateral branches of the intercostal artery, and superficial epigastric artery, as they approached the costal margin or anterior axillary line and formed a relatively dense vascular network.抄録全体を表示PDF形式でダウンロード (22244K) -

ジャーナル フリーWe clinicopathologically studied 19 patients with oral squamous cell carcinoma and secondary metastasis to the cervical lymph nodes who had undergone radical neck dissection between 1978 and 1995 at our department.
The results were as follows:
1. Secondary metastasis to the cervical lymph nodes was found in 12.1% of N 0 cases.
2. A higher frequency of secondary metastasis to the cervical lymph nodes was detected in patients with primary lesions of the gingiva of the upper jaw and of the tongue.
3. As for the distribution of involved lymph nodes, the majority were recognized at Level 2, Level 3, or both.
4. The five-year-survival rate was 48.9% in patients with secondary metastasis.
5. Metastatic lymph nodes showed intranodal proliferation in 71.1% of cases and 28.9% of extranodal spread in 28.9% of cases.
6. In patients with of high grade malignancy of the primary lesion, the frequency of lymph nodes metastasis and tumor spread to the cervical lymph nodes was higher than in patients with other grades of malignancy.抄録全体を表示PDF形式でダウンロード (869K) -

ジャーナル フリーChanges in preoperative and postoperative temporomandibular joint (TMJ) symptoms in patients with prognathism who underwent sagittal split ramus osteotomy (SSRO) of the mandible, including repositioning of the proximal segment and titanium screw fixation, were evaluated. Symptoms (sounds and pain) of the TMJ were checked preoperatively and 3, 6, 12 (1 year), and 24 (2 years) months after surgery. As of 1 or 2 years after surgety, TMJ sounds had resolved in about 70% of the patients with preoperative joint sounds. As of 6 months after the operation, joint pain had also resolved in all patients who had this sympotom preoperatively. On the other hand, joint symptoms developed in only about 5% of the patients who had no preoperative joint symptoms as of 1 or 2 years after surgery. In conclusion, the results of this study suggest that most of the preoperative TMJ symptoms in patients with prognathism resolve after SSRO with repositioning of the proximal segment and titanium screw fixation, although the preoperative condylar position should be maintained.抄録全体を表示PDF形式でダウンロード (754K) -

ジャーナル フリーWhether surgical or conservative therapy is indicated in mandibular condylar fractures remains controversial because there are no definitive criteria on which to base this decision. We treated 144 patients with a diagnosis of mandibular condylar fracture at the First Department of Oral and Maxillofacial Surgery, Kyushu Dental College Hospital during the 9-year-period from 1986 through 1994. Seventy-seven of the 144 patients responded to a questionnaire, and 32 patients were recalled. We analyzed the outcome of treatment for mandibular condylar fracture. The results were as follows.
1. Analysis of the questionnaire indicated no difference between the surgical treatment group and the conservative treatment group with regard to clinical outcome. However, the clinical outcome after the enucleation of fractured fragments was bad.
2. In the conservative treatment group, the clinical outcome of cases involving dislocated and disarticulated mandibular condylar fractures at the upper neck and head was bad in patients who were 30 years of age or older.
3. As for the morphological outcome, the surgical treatment group was better than the conservative treatment group.
Future studies should investigate indications for surgical treatment in patients with mandibular fractures who are over 30 years old, those in whom the fractured fragment can undergo reduction, and those with dislocation and disarticulation at the upper neck and head.抄録全体を表示PDF形式でダウンロード (794K) -

ジャーナル フリーFour cases of mandibular hypomobility who had characteristic bilateral mandibular ramus enlargement are reported. Neither internal derangement nor locking due to coronoid process hyperplasia were recongnized in any patient.
All four patients were female and had no history of pain or noise in the temporomandibular joint (TMJ) region. Mouth opening was limited to between 23mm and 28mm, and there were no signs of pain or clicking of the TMJ. On magnetic resonance imaging, there was no evidence of permanent disc displacement. On cephalometric measurements, the lower posterior face height was high, the width of the ramus was large, and the gonial angle was small. The mandibular configuration of the patients was square-shaped, which was considered related to limited mouth opening.抄録全体を表示PDF形式でダウンロード (8109K) -

ジャーナル フリーAn extremely rare case of 10q trisomy syndrome with cleft palate is presented. A 1-month-old girl with characteristic facial features was referred to our clinic for treatment of cleft palate. Her medical history included congenital heart disease, hydrocephaly, and cleft palate. Chromosomal examination revealed a karyotype of 46, XX, -1, +der (1) t (1; 10)(q44; q24.3) mat. A diagnosis of 10q trisomy syndrome was made. She received palatoplasty for cleft palate at the age of 2 years and 5 months. The postoperative course was uneventful. One year 5 months after surgery, body weight had increased favorably and there was no food leakage from the nostrils, but her speech had not sufficiently improved.抄録全体を表示PDF形式でダウンロード (3147K)
