Differences in the predicted nasoseptal flap length among races: A propensity score matching analysis.

Abstract

ObjectivesWe compared the lengths of a nasoseptal flap (NSF) and skull base according to race, age, and sex.MethodsWe performed paranasal sinus computed tomography in 19,961 adult patients between 2003 and 2022. The race of the patients was East Asian (n = 71), Caucasian (n = 71), or Middle Eastern (n = 71). The expected lengths of the NSF and anterior skull base defect were measured and analyzed according to race, age, and sex.ResultsCompared with Caucasians and Middle Easterners, East Asians had a shorter NSF length (p ConclusionsEast Asians and females had a shorter NSF length and lower ratio of expected NSF to surgical defect lengths after anterior skull base reconstruction compared with the other races and with males, respectively. Anatomical differences should be considered when long NSF lengths are required, such as for anterior skull base reconstruction.
