摘要
Currently popular transsphenoidal approaches to the pituitary include sublabial, external rhinoplasty, alotomy, and transnasal techniques. The conventional sublabial approach remains the workhorse method despite postoperative lip edema, potential difficulty for denture wearers, and troublesome persistent upper lip and incisor teeth numbness. We traced the courses of the nasopalatine, infraorbital, and anterior superior alveolar nerves in 41 cadaveric half-head dissection to determine the exact contribution to upper lip and incisor teeth innervation. We then conducted a retrospective patient survey of 25 sublabial, 28 external rhinoplasty, 23 alotomy, and 12 transnasal approaches to the hypophysis to assess the incidence of upper lip and incisor teeth paresthesias lasting longer than 1 month. We conclude that rhinoplastic techniques are superior to the sublabial approach in limiting upper lip and incisor teeth numbness without compromising neurosurgical exposure for hypophysectomy.
