Abstract
Introduction: The purpose of this study was to obtain insight into the perioperative condition of the maxillary sinus in the LeFort I osteotomy by evaluating clinically and radiographically. Materials and methods: 25 patients who required conventional LeFort I procedures for orthognathic correction were included in the study. Damage to the maxillary sinus during the procedure and its recovery were prospectively analysed using validated questionnaires for sino-nasal complaints using RSOM-31 (RSOM − rhinosinusitis outcome measure), VAS score (VAS − visual analogue scale) and CT scan to compare and analyse changes in maxillary sinus prior to surgery and postoperatively 2 months after the surgery. The scores obtained from RSOM-31 questionnaire was analysed using Chi-square test, VAS questionnaire was interpreted using Wilcoxon sign rank test and CT scan findings were analysed using Fischer's exact test. Results: Mucosal thickening assessed using CT scan was the only consistent finding that was evident for all the patients who underwent LeFort I osteotomy which showed a statistically significant results of P < 0.05, whereas clinical correlation showed insignificant results of P > 0.05. Conclusion: In our attempt on extensive patient analysis we found that mucosal thickening was the prime alteration that was observed radiographically and no clinical changes were evident.

Summary
Dentofacial deformities affect approximately 20% of the population who present with various degrees of functional and aesthetic compromise [1]. Correction of these deformities require orthognathic surgeries which involves mobilization, repositioning and fixation of the maxilla and mandible. LeFort I osteotomy is the most frequently performed orthognathic surgery to correct such dentofacial deformities. Performing this surgery had shown to have a direct effect on the morphology of nasal cavities as well as the maxillary sinus, Hypertrophic turbinates, deviated septum and other nasal conditions which may obstruct the nasal passage [2]. RSOM-31 (rhinosinusitis outcome measure) was used to assess complaints concerning sino-nasal pathology, VAS score
