STUDY ON THE QUALITY OF LIFE IN PATIENTS WITH DENTO-MAXILLARY ANOMALIES TREATED USING THE "SURGERY FIRST" APPROACH

Orthognathic surgery, particularly the "surgery first" approach, has become a pivotal intervention for improving the quality of life of patients with dento-maxillary anomalies. This prospective analytical study aimed to evaluate changes in oral health-related quality of life using the Orthognathic Quality of Life Questionnaire (OQLQ) and Oral Health Impact Profile 49 (OHIP-49) of patients with dento-maxillary anomalies treated using the "surgery first" approach. Material and methods: Eighteen patients aged 18–35 years with Class II and III dento-maxillary anomalies treated at "Sf. Spiridon" Hospital in Iași were assessed preoperatively and three months postoperatively. The results demonstrated significant improvements across multiple domains. Results: The mean OQLQ score decreased from 82.5 to 28.27 (p=0.012p=0.012p=0.012), reflecting substantial enhancements in aesthetic impact, oral function, and psychosocial well-being. Similarly, OHIP-49 scores showed a significant reduction in functional limitation (p=0.021p=0.021p=0.021) and trends toward improvement in other domains. These findings align with previous studies, confirming the efficacy of the "surgery first" approach in reduci
