“…On the other hand, increasing evidence suggests that SRP can also be a treatment for some cases of OD 35 . This notion is supported by studies that reveal that early preoperative (6w) scores did not improve or were worse than before the SP or SRP, only to improve later in the follow-up period 24,29,[36][37][38] . A rational analysis is lacking in the literature regarding the long-term effects of SRP on OF.…”

Septorhinoplasty and the Late Impact on Olfactory Function: A Review and Meta-analysis

et al. 2022

Background: Septorhinoplasty (SRP) is one of the most commonly performed procedures worldwide. There is a recognized debate about the impact of nasal surgery on olfactory function (OF). The study's objective was to assess the effect of SRP on late postoperative OF. Methods: A comprehensive review and meta-analysis were employed to assess OF after SRP. All the integrated studies used objective instruments to quantify OF before and after surgery. A literature search was conducted, and the selected works were evaluated, computed, and finally included in a meta-analysis. The risk of bias was assessed using the NIH Guidance for Evaluating the Quality of Before-After (Pre-Post) Studies with No Control Group. Only the latest follow-up OF measurements provided by each research was considered in the analysis. The 95 percent confidence interval of the effect magnitude for each study was calculated to elucidate effect sizes. Results: There were 11 studies included in the analysis. Five studies reported late OF improvement (45.5%), five studies reported no alteration in OF (45.5%), and only one study reported OF impairment after SRP (9%). Some studies describe a transitory decline in OF shortly following surgery, followed by postoperative improvement. A pooled meta-analysis showed that OF was not significantly altered after SRP (p = 0.10) in the late follow-up. Conclusions: SRP surgery seems to constitute a safe procedure concerning OF in the long term. According to research, OF may deteriorate temporarily after surgery with later improvement, sometimes to higher values than baseline. The anticipated evolution of OF after intervention could be discussed during the preoperative consultation for SRP.

Introduction: All surgical procedures on nose affect the olfactory function to some extent. There are different viewpoints about olfactory function after septorhinoplasty. We aim to investigate smell perception changes in patients following septorhinoplasty. In this study the use of Rapid Smell Test (RST) as a fast and reliable clinical tool was investigated. Methods: A prospective cohort study was done in Rasool Akram teaching hospital in 2018 and 2019. Group of 74 septorhinoplasty candidates aged over 18 was selected by convenience. Persian Smell Identification Test (PSIT) and rapid smell test (RST) was obtained from patients before surgery and one month after, if needed three months after and six months after. In addition for patients with dysfunction in any of follow up periods (one month, 3 months and 6 months after surgery) smell magnitude test (SMT) was used. All data were analyzed using Statistical Package for Social Sciences, version 24.0 (IBM SPSS Statistics Inc., Chicago, IL, USA). Results: Out of 74 patients participating in this study 67 were female. Mean age of 25.68±5.18 years was recorded for participants. All patients before surgery had PSIT score more than 19 and the mean PSIT score before operation was 22.63±1.39. Also all patients scored 5 out of 5 in RST before surgery. Mean PSIT score one month after surgery decreased to 22.21±2.20 but still 93 percent (69 patients) of participants were in range for normal olfactory function. We recorded this to be significant (p value = 0.044). RST after one month showed the same results. The difference between RST before and after surgery was also significant (p value = 0.024). For those 5 patients with abnormal olfactory function PSIT and RST were done 3 months after operation which determines normal olfactory function for all of them. As well as PSIT, RST also shows the same results and five participants recorded 5 out of 5 three months after surgery. Conclusion: This study showed changes in olfactory function after septorhinoplasty will resolve at most 3 months after surgery and it is safe to say there is no effect on olfactory function three months after operation. Also we demonstrated that RST can be a fast and reliable tool for assessing patients’ olfactory function in clinical setting.

“…17,18 There are studies in literature that have reported olfactory disorders forming in the early period after nasal surgery that have recovered in the long term with the elimination of edema and inflammation. 17,19 In a study by Apuhan et al, biopsies taken from lateral, anterior, and medial surfaces of concha of patients operated on for a diagnosis of CB were found to include nerve tissue at rates of 81.4%, 60%, and 32.8%, respectively, and it was also stated that lateral turbinectomy could cause loss of the sense of smell. 1 The BSIT is an easily completed test with proven objectivity, validity, and reliability, not affected by the educational level, ethnicity, or language of the respondents.…”

Comparison of the Effects of 2 Surgical Techniques Used in the Treatment of Concha Bullosa on Olfactory Functions

Introduction: Concha bullosa (CB), which is pneumatization of the concha, is one of the most commonly seen anatomic variations of the lateral nasal wall. Objective: To investigate the effects on olfactory function of lateral turbinectomy and crushing methods used in the surgical treatment of CB. Methods: The study included a total of 47 patients operated on for a diagnosis of CB and nasal septum deviation. The patients comprised 22 females and 25 males, with bilateral CB in 18 cases and unilateral in 29 cases. Intervention was made to a total of 65 CB. The cases were separated as those applied with septoplasty and lateral turbinectomy in group 1 (n = 34) and those applied with the septoplasty and crushing method in group 2 (n = 31). The olfactory function of the patients was evaluated preoperatively and at 3 months postoperatively with the Brief Smell Identification Test. Results: A statistically significant increase was determined in the postoperative smell test results compared with the preoperative values in both group 1 ( P = .021) and group 2 ( P = .001). When the change in the smell test results from preoperative to postoperative was compared between the groups, the increase in group 2 was determined to be statistically significantly greater ( P = .002). Conclusion: The results of this study showed that the crushing method in surgical treatment of CB increased olfactory functions more than the lateral resection method, and as the improvement in olfactory functions was greater, this demonstrated that only increasing the nasal cavity is not sufficient and the nasal mucosa should be protected as far as possible.
