Diastasis of the maxillary bone: an unusual complication of transsphenoidal surgery

Diastasis of the intermaxillary suture is an unusual complication of the transsphenoidal approach to the sella turcica. Over the 1977-1989 twelve-year-period, 192 procedures were performed at our Center. This complication occurred only once, in a senile patient with marked osteoporosis. It did not alter the course of the operation, nor did it create additional problems during the postoperative period.
