The transseptal approach to lesions of the pituitary and parasellar regions.
In a series of 505 consecutive procedures, the transseptal-transsphenoidal pituitary operation has proved safe and effective. The overall mortality in this series is 1.39%. A wide variety of sphenoid and sellar lesions and nearly every pituitary adenoma have been found suitable for the exposure provided through the sublabial-transseptal approach. This statement rests on the premise that both the rhinologist's and the neurosurgeon's skills are optimally applied to each case. The role of the otorhinolaryngologist is defined in this paper, and the benefits of the team approach are explored. An interpretive history of the transsphenoidal approach is presented, and the evolution of the transseptal technique developed at the Mayo Clinic from 1972 to 1978 is reviewed. Emphasizing the rhinologic aspects, all details of the surgical technique are described and illustrated. Our experience with the special endocrine syndromes is also reviewed to spotlight clinical features that require individual consideration by the rhinologic surgeon.
