Effect of orthognathic surgery on temporomandibular joint pain. A systematic review.

Objective: Dentofacial deformities affect patients' social relations, self-esteem and oral health-related quality of life. Studies show that patients treated for malocclusions with orthodontics/orthognathic surgery have significantly more temporomandibular disorders (TMDs) than others. The aim of the work was to evaluate the effect of orthognathic surgery on temporomandibular joint pain.

Material and methods: The literature review was performed according to PRISMA guidelines. Publications were searched in databases: PubMed, The Cochrane Library, Science Direct. A combination of keywords was used and the selection criteria were applied. Articles written in English and studies conducted on people who underwent bilateral sagittal split osteotomy and/or Le Fort I osteotomy and arthralgia were evaluated before and after surgery were included in this study.

Results: 10 publications were selected, including a total of 1143 patients. When evaluating arthralgia, statistically significant positive results were seen at 6 months after surgery, at later postoperative periods results remained beneficial.

Conclusion: Included studies showed that patients with dentofacial deformities, who underwent orthodontic-orthognathic treatment, less often complains about arthralgia.
