This study was designed to explore the impact of medial osteotomy on olfactory function. This nonrandomized, prospective study included 60 adult patients who underwent open technique septoplasty (group 1), rhinoplasty with only lateral osteotomy (group 2), and septorhinoplasty with medial and lateral osteotomies (group 3). Olfactory functions were evaluated by using the Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test. The CCCRC test includes the butanol threshold test and smell identification test using common smells. The butanol threshold test and smell identification test scores of each group were recorded preoperatively and at 1st and 4th months and compared. Each group is consisted of 20 patients. The preoperative smell identification test and butanol threshold test scores were similar in each group. The smell identification test, butanol threshold test, and CCCRC olfactory test scores of the 1st month were statistically significantly low in group 3. There was no statistically significant difference between the groups at 4th month postoperatively. The present study is the first analysis of the effect of medial osteotomy on olfactory function. Medial osteotomy may decrease the olfactory function in early time, but afterwards olfaction could recover at preoperative levels.
