Abstract
Objective The nasoseptal flap (NSF) is considered the primary vascularized flap for reconstruction
of dural defects with endoscopic endonasal surgery (EES) of the skull base. However,
the complications and morbidities associated with this reconstructive flap are poorly
understood. This article presents a systematic review of the complications and morbidities
related to the use of the NSF in skull base surgery.
Method A systematic review of the literature based on published guidelines was performed
to identify potential complications and morbidities related to the NSF. The MEDLINE
and Embase databases were searched from January 1, 1950 to February 5, 2018.
Results Twenty-seven articles were identified. Reported complications were as follows: NSF
necrosis (4 studies; [0–1.3%]), mucocele formation (5 studies; [0–3.6%]), septal perforation
(6 studies, [0–14.4%]), nasal dorsum collapse (2 studies, [0.7–5.8%]), effects on
quality of life (QoL) (8 studies), and olfactory loss (11 studies).
Conclusion Although complications associated with the NSF may be underreported in the literature,
the NSF appears to be a safe and reliable reconstructive flap in EES of the skull
base.
