Abstract
OBJECTIVES: Although the routine use of computed tomography (CT) is controversial, it is employed in the preoperative screening of patients undergoing septoplasty or septorhinoplasty. The aim of this study was to evaluate the incidence and radiological characteristics of incidentally found sinus pathologies on screening CT in patients who underwent elective septoplasty or septorhinoplasty.
METHODS: We retrospectively reviewed the patients who underwent septoplasty and septorhinoplasty performed by a single surgeon (Y.J.J.) at Asan Medical Center between January 2016 and December 2017. CT images of 372 patients who had agreed to undergo preoperative CT were reviewed to determine the location and extent of incidental sinus opacifications.
RESULTS: Of the 372 patients, 107 (28.8%) showed incidental sinus lesions on CT images. Opacifications were mainly found in the maxillary sinus (73, 68.2%), followed by the ethmoid (34, 31.8%), sphenoid (10, 9.3%), and frontal (3, 2.8%) sinuses. The most common sinus lesion was retention cyst (55, 51.4%), and the second most common one was opacification and mucosal thickening (46, 43%). Other lesions such as osteoma (3, 2.8%), dental cyst (2, 1.9%), and mucocele (1, 0.9%) were rarely found.
CONCLUSIONS: In patients undergoing septoplasty or septorhinoplasty, the incidence of incidental sinus lesions was approximately 28.8% (107/372). This results indicate that preoperative CT in patients undergoing septoplasty or septorhinoplasty might be helpful to surgeons not only for better understanding the anatomical detail but also for detecting hidden paranasal sinus disease.
