Assessment of Quality of Life and Stomatognathic Dysfunction in Patients with Maxillofacial Defects Before Orthognathic Surgery

Abstract

Background: Individuals with maxillofacial deformities are concerned not only with their facial appearance but also experience dysfunctions of the stomatognathic system, including mastication, swallowing, speech, and breathing. These impairments may lead to negative psychological responses and a reduced quality of life. Aim: The aim of this study was to assess the quality of life and analyse reported dysfunctions of the stomatognathic system in orthognathic patients prior to surgical intervention. Material and methods: The study group (SG) comprised 63 patients with maxillofacial deformities scheduled for orthognathic surgery. The control group (CG) consisted of 70 patients with malocclusions undergoing orthodontic treatment who did not meet the criteria for surgical intervention. Quality of life was assessed in all participants using the Orthognathic Quality of Life Questionnaire (OQLQ), along with a self-reported questionnaire evaluating the presence of stomatognathic system dysfunctions (SS). Results: Significant differences were observed between the study groups regarding all quality-of-life indicators for orthodontic and orthognathic patients. Patients in the SG more frequently reported difficulties in the specified stomatognathic system functions compared to those in the CG. No statistically significant differences were found between SG patients with Class II and Class III malocclusions in terms of OQLQ scores or the frequency of reported SS dysfunctions. Regarding sex differences, women reported a lower overall quality of life and scored lower in social dimensions related to facial deformity and aesthetics compared to men. No significant correlations were observed between the age of orthognathic patients and quality-of-life assessment. Conclusions 1. Orthognathic patients exhibit a poorer quality of life and a higher prevalence of stomatognathic system dysfunctions compared to patients with malocclusions who do not require surgery. The type of skeletal deformity in surgical patients does not influence quality of life or the frequency of stomatognathic dysfunctions. 2. Unlike age, the patient’s sex is a significant factor in the quality of life before orthognathic surgery.
