Osteotomy design and execution.

Craniofacial osteotomies are an integral part of contemporary neurosurgery because of their ability to provide substantially more exposure to deepseated lesions with reduced brain retraction. A systematic approach to the performance of these osteotomies coupled with meticulous bone work capitalizes on their advantages without producing any significant cosmetic defects. As their indications are progressively more clearly defined and familiarity and facility are gained by the surgeons performing them, operative time and morbidity should decrease.

Cosmetic considerations in cranial base surgery.

Recent advances in the surgical techniques for the resection of cranial base tumors have allowed for improved degrees of tumor resection, functional outcomes, and esthetic results. If the resection and functional results are not compromised by procedures providing excellent cosmetic outcomes, there is no reason to ignore or compromise the esthetic aspect with regard to technical execution and planning. A thorough assessment of the patient's preoperative deficits and tumor anatomy and a working knowledge of the available cranial base approaches and their combinations permit the surgeon to design an approach that allows for optimal tumor resection with the best possible cosmetic result.
