Surgical access to multicystic lesions, by sagittal splitting of the lower jaw.

A case is presented of a large, multiloculated primordial cyst in the lower jaw. In treatment planning of the lesion, a hemimandibulectomy had been seriously considered, but seemed to be too agressive a therapy for a non-malignant lesion. However, the recurrence rate of multiloculated cysts made a meticulous enucleation necessary. By employing a sagittal splitting of the right half of the mandible a good surgical access was provided and the cysts could be removed very thoroughly. Recurrence was not observed during a 3 years follow up period.

Early unicystic ameloblastoma: report of case.

The occurrence of an atypical cystic lesion of the mandible in a 13-year-old boy is described. At first, a diagnosis could not be made. The biopsy specimen showed features resembling an ordinary follicular cyst, together with areas in which distinct alterations in the epithelium were noticed. These alterations seemed to be in accordance with findings of Vickers and Gorlin in cases of early or unicystic ameloblastoma. The lesion was treated by enucleation. After almost three years, no recurrence has been noticed. Long-term follow-up care is necessary. The case illustrates the obvious need for meticulous histologic examination of every cystic lesion of the jaw.

Anaesthetic experiences in orthodontic surgery.

The anaesthetic experiences and problems have been analysed, based on 100 orthognathic operations. The material includes all kinds of operations; operating time was about 4 hours, except for 8 very extensive procedures, lasting 6--7 hours. The importance of adequate premedication is emphasized. The use of nasal drops for decongestion is especially highly recommended for the prevention of bleeding during nasal intubation. An armoured nasal tube is always used; however, special care must be taken to detect leaks on the cuff. On four occasions the tubes had to be changed because of leaks in the cuff. The most annoying complication was tachycardia, due to: insufficient premedication, insufficient analgesics during operation, or the use of hypotensive drugs. Blood loss was clearly diminished by controlled hypotension. Postoperative vomiting was prevented by the use of a nasogastric tube for the first 6--8 hours. Major complications were not encountered.
