Late Postoperative Rhinological Complications After Microscopic Transnasal Hypophysectomy
AIM: Major complications of microscopic transnasal hypophyseal surgery (MTHS), such as cerebrospinal fluid rhinorrhea, carotid
injury, and optic nerve injury, are very rare. However, late rhinological complications can be ignored because they are a minor cause
of morbidity compared with major complications. In this study, we extensively examined postoperative rhinological complications
in patients who underwent MTHS for pituitary adenoma.
MATERIAL and METHODS: Thirty-one patients diagnosed with pituitary adenoma, who underwent MTHS and whose preoperative
nasal examinations were recorded between January 2007 and January 2014, were included in the study. A detailed rhinological
examination of the patients was performed.
RESULTS: A total of 12 of 31 patients (38.7%) had a perforated nasal septum, and synechiae were detected in the nasal cavities
of 13 patients (42%). Anosmia occurred in three patients, hyposmia in two, and a nasal tip deflection and saddle nose deformity
were detected in one patient with a perforated nasal septum. No perinasal loss of sense, oronasal fistula, or purulent secretion in
the nasal cavity was found in any patient.
CONCLUSION: The nasal structures, particularly the nasal septum mucosa, should be treated gently during MTHS. The nasal
stages of the operation should be performed with the help of an otolaryngologist until adequate experience is gained.
