The TMJ dysfunction syndrome before and after sagittal split osteotomy of the rami.
280 patients with different types of mandibular deformities (prognathism, retrognathia, open bite, asymmetry) had been operated on by sagittal split osteotomy of the rami. The patients, routinely checked preoperatively, were found to present subjective or objective TMJ dysfunction symptoms with an incidence of 40.8%. After surgery the incidence of such symptoms in the same patients was 11.1%. The patients with no TMJ dysfunction symptoms preoperatively, presented such symptoms with an incidence of 3.7% postoperatively, a percentage very low in comparison with other statistics.
Facial paresis following sagittal split osteotomy. Report of two cases.
Two cases of transient facial nerve paresis following sagittal split osteotomy have been presented. The patients had complete recovery of nerve function within 5 months in the first case and 8 months in the second case.
Infection after orthognathic surgery, with and without preventive antibiotics.
Prophylactic antibiotics are often administered during orthognathic surgery to prevent infection. Prophylactic antibiotics were given to a group of 389 orthognathic surgery patients, with the development of 1 case of acute and 12 cases of chronic infection. One case of chronic infection appeared in another group of 76 patients who had not received prophylactic antibiotics. Antibiotics seem not necessary for routine use in orthognathic operations, as a prophylaxis.
Parotid benign tumors: comments on surgical treatment of 263 cases.
263 patients with benign parotid gland tumors have been operated upon, from 1970 through 1980. Of this total number of tumors, according to their histopathologic examination, 185 corresponded to pleomorphic adenoma, 24 to Warthin's tumor, 10 to recurrent pleomorphic adenomas (at first operated on elsewhere) and 44 to miscellaneous tumors or tumor-like lesions (simple cyst, lymphoepithelial lesion, branchial cleft cysts, lymph node hyperplasia etc.). 25 cases of pleomorphic adenoma, operated on during the past 24 months, were not evaluated as far as recurrence is concerned, because their follow-up was insufficiently long. The operative procedures used by us for pleomorphic adenoma surgery were: (a) pericapsular (extracapsular) excision, with a margin of normal parotid gland tissue without preparation of the fascial nerve, for 98 small size and superficially sited pleomorphic adenomas (52.6%); (b) subtotal parotidectomy (superficial lobectomy) with preparation of the facial nerve for 78 tumors (42.5%); (c) total parotidectomy with preservation of the nerve for 9 tumors located on the deep lobe of the gland (4.9%). We did not see any permanent facial palsy, and not one case of recurrence.

Incidence of lymph node metastasis in elective (prophylactic) neck dissection for oral carcinoma.
For cancers of the tongue, floor of mouth, mandibular gingiva and buccal mucosa, in which the widest diameter is greater than 2 cm, we perform neck dissection in continuity with resection of the primary growth as a part of the planned therapy,regardles of the clinical state of the cervical lymph nodes. Whenever the lesion is so situated that an in-continuity neck dissection cannot be performed (cancer of the palate) it may be wise to delay neck dissection until the lymph nodes become clinically apparent.

Free transplantation of lyophilized dura for vestibuloplasty: a clinical and histological study.
Covering epithelial defects in the oral cavity is often neccessary in maxillofacial surgery. Special problems arise in preprosthetic surgery because requisites for function and quality of epithelial grafts must be satisfied. Using free heterologous lyophilized dura grafts for vestibular sulcoplasty in 23 patients, we observed a good clinical and histological healing process. Considering the necessity of a second operation for skin or mucosal grafts (and the limited source of mucosa), we believe that the lyophilized dura can be used successfully in preprosthetic surgery.
