Complications of trans-sphenoidal surgery: the Wellington experience.
BACKGROUND
All patients who underwent trans-sphenoidal surgery between January 1984 and December 1998 were reviewed to assess morbidity resulting from this operation.


METHODS
There were 185 operations on 165 patients. The operative approach was sublabial in 80 cases and transnasal in 105. One surgeon (VB) performed the vast majority of operations.


RESULTS
Complications included nasal perforation (7.6%), transient diabetes insipidus (4.9%), permanent diabetes insipidus (3.8%), cerebrospinal fluid fistula (4.3%), donor site haematoma (2.2%) and residual tumour haemorrhage (1.6%) causing ophthalmoplegia (1.1%) and loss of vision (1.1%). Other complications included epistaxis (1.1%), meningitis (0.5%) and sinusitis (0.5%). Injury to the anterior superior alveolar nerve also occurred in the sublabial approach in 6.3% of patients. There were no perioperative deaths.


CONCLUSIONS
There is a small but significant risk of a number of complications that should be considered for informed consent of this procedure.
