Conchopexy Suture versus Bolgerization in preventing middle turbinate lateralisation following FESS

Abstract

Background: Middle turbinate lateralisation is the most common minor post-operative complication following functional endoscopic sinus surgery. This study aimed to compare the outcome between Conchopexy suture and Bolgerization method in preventing middle turbinate lateralisation. Methodology: This was a prospective, comparative and interventional study conducted from May 2018 to November 2019 at Tribhuvan University Teaching Hospital, Kathmandu, Nepal. A total of 68 patients were divided equally into two groups. Following functional endoscopic sinus surgery, the middle turbinate was medialised either by Conchopexy suture or Bolgerization technique. Postoperative assessment was done on the second and 12th week of surgery, where the position of the middle turbinate and status of the sinus cavity were assessed using perioperative sinus endoscopic (POSE) score. Chi-square test and unpaired t test were used for comparison of postoperative results between two groups taking p value of < 0.05 as statistically significant. Results: Lateralised middle turbinate and mean POSE score was 5/34 (14.8%) and 2.1±1.25, respectively, in Conchopexy group whilst in Bolgerization group it was 6/34 (17.6%) and 2.5±1.46. However, the observed differences were not statistically significant. Conclusion: Conchopexy suture and Bolgerization techniques were equally effective in preventing middle turbinate lateralisation. Hence, either of these techniques could be used as an adjunct to FESS to avoid middle turbinate lateralisation.
