OBJECTIVE: Septorhinoplasty (SRP), one of the most commonly performed rhinologic surgery procedures, can affect olfactory function; however, the findings of studies investigating smell following SRP are controversial. We used a culturally adapted modified Brief Smell Identification Test (B-SIT) to investigate the long- and short-term effects of SRP on olfactory function. METHODS: We enrolled 59 patients admitted to the Ear-Nose-Throat Clinic, who were complaining of external nasal deformity and nasal obstruction. Functional SRP was performed on all cases. The B-SIT was administered prior to surgery and at 4 and 12 weeks post-surgery. The smell identification score (SIS) reflected the number of correct answers. In addition, we investigated the effects of gender and smoking on olfactory function and whether the SRP procedure changed these associations. RESULTS: The mean preoperative, 4-week, and 12-week postoperative SISs were 10.15±1.30, 10.21±1.52, and 10.92±0.95, respectively. The difference between the preoperative and 4-week postoperative SISs was not statistically significant; however, the 12-week postoperative score was significantly different from the preoperative and 4-week postoperative scores. Furthermore, the repeated measures analysis according to gender and smoking habit revealed a significant difference between the 4-and 12-week postoperative SISs. One patient developed postoperative anosmia; however, the patient recovered in the 12-week postoperative period. CONCLUSION: SRP surgery is a safe procedure in terms of olfactory function. In addition, olfactory function may increase following surgery as a result of improved nasal airflow.
