| Abstract |
THE AIM OF STUDY: The transseptal-transsphenoidal approach (TSA) for pituitary tumors may alter nasal functions, including nasal respiration and olfaction. The aim of this study was to investigate the efficacy of TSA in terms of nasal functions.
MATERIALS AND METHODS
Twenty two cases of pituitary tumors, managed at Seoul National University Hospital from May 1997 through March 1998, were included in this prospective study. Nasal functions were evaluated preoperatively and 2 months after the operation through symptom questionnaires, rhinomanometry, acoustic rhinometry and the butanol thres-hold test.
Results
The subjective nasal symptoms, including nasal obstruction and olfaction, were not changed following the operation in 72% and 86% of the cases, respectively. In the objective findings, total nasal resistance was not grossly changed after the operation, however, cross-sectional areas at C-notch and 3.3 cm from the anterior nasal spine increased significantly after the operation. Mucosal response to a topical vasoconstrictor after the operation was less effective than before the preoperation.
Conclusion
TSA for pituitary tumors may be a safe and effective technique in preserving nasal functions subjectively and objectively. |
