Anthropometric Facial Changes After Orthognathic Surgery and Their Relation With Oral Health Related Quality of Life

Abstract

PURPOSE: The aim of the present study was to determine the impacts of orthognathic surgery on soft tissue on frontal and profile views and their relation with patient's quality of life. METHODS: Twenty-nine patients with severe skeletal class III malocclusion who were candidate for bimaxillary orthognathic surgery consisted of 1-piece Lefort I surgery with bilateral sagittal split osteotomy were selected. Oral health was assessed by short from of Oral Health Impact Profile-14 questionnaire. Facial anthropometric measurements were conducted before starting any treatment and 6 months after orthognathic surgery according to Farkas anthropometric study. The correlation between facial changes due to treatment and oral health were tested by Pearson correlation analysis. RESULTS: No significant differences were observed in Oral Health Impact Profile-14 scores with regard to genders. Decreased vermilion total upper lip height index correlates positively with feeling difficult to relax. Increasing in medial-lateral cutaneous upper lip height index correlates negatively with dissatisfaction with diet. Increased upper face-face height index correlates positively with feeling uncomfortable to eat any foods and feeling a bit irritable with other people. CONCLUSION: Oral health-related quality of life can be affected not only by the objective aesthetic criterion but also by different factors like their attitude toward aesthetic, surgery side effects.
