Patient Wellbeing and Quality of Life After Nasoseptal Flap Closure for Endoscopic Skull Base Reconstruction.

BACKGROUND

The endoscopic endonasal approach to the skull base avoids some of the surgical morbidity associated with a transcranial approach, however it often results in large skull-base defects requiring secure closure. The nasoseptal flap has become the preferred method for closure of such defects but may be associated with its own morbidity.

METHODS

A consecutive cohort of patients with skull base pathology with prospectively collected quality of life data using ASBQ and SNOT was analysed. They were grouped into those who received a nasoseptal flap and those who did not. Pre-operative total ASBQ and SNOT scores, and their individual components, were compared to data collected at days 1, 3, and 7; six-weeks; and 3, 6, and 12-months postoperatively.

RESULTS

Of 158 patients available for analysis, nasoseptal flaps were performed in 52 (33%). Average follow-up (±standard deviation) was 8.1 ± 3.9 months for ASBQ data and 8.2 ± 3.8 months for SNOT data. In the first post-operative week, nasal symptoms and otalgia were worse in the flap group. At six-weeks and beyond, there was no difference between groups in overall ASBQ or SNOT scores, or in the rate of clinically-significant improvement in SNOT or ASBQ scores or their components.

CONCLUSION

In the largest cohort of patients to date, the use of a nasoseptal flap is associated with nasal symptoms and otalgia in the acute post-operative period, but is not associated with any long-term detriment to quality of life after endoscopic skull base surgery.
