Evaluation of quality of life after orthognathic surgery in obstructive sleep apnea syndrome: a systematic review.

Objectives: To develop a systematic review of patient perspectives on the treatment of obstructive sleep apnea syndrome (OSAS) after undergoing orthognathic advancement surgery.

Materials and methods: This systematic review adhered to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines, and Patient, Intervention, Comparison, and Outcome (PICO) methodology was employed to formulate the research question. A literature search was performed using the following databases: Cochrane Library (Trials), PubMed via MEDLINE, Embase, and Web of Science (all databases). The Newcastle-Ottawa Scale was used to assess quality of the studies.

Results: Initially, 1407 articles were retrieved from diverse databases, and these were subjected to initial scrutiny. Subsequently, 17 articles were selected for thorough quality analysis and 6 studies for quantitative analysis. Most studies were classified as good quality. Maxillomandibular advancement surgery appeared to enhance patient satisfaction in cases of moderate to severe adult OSAS.

Conclusions: Maxillomandibular advancement surgery significantly improves patients' subjective overall quality of life, improving by 6.36 points in questionnaire ratings and demonstrating long-term stability.
