Abstract
Purpose: The purpose of this study was to investigate characteristics of mandibular head morphology and temporomandibular joint (TMJ) disorders (TMDs) on the deviation side (DS) and non-deviation side (NDS) in patients with facial asymmetry (FA).
Methods: Thirty patients diagnosed with FA were enrolled. Preoperative and postoperative joint sound and pain were evaluated in terms of clinical symptoms, and pre- and postoperative mandibular head morphology factors shown by computed tomography. In addition, magnetic resonance imaging findings were used to evaluate preoperative joint disc position and joint effusion (JE).
Results: The patients included 12 (40.0%) males and 18 (60.0%) females, with a mean age of 25.8 years. There were no significant differences regarding clinical symptoms between patients affected on the DS and those on the NDS. Preoperatively, the DS group showed a total of 4 joints (13.3%) with mandibular condyle head deformity, while postoperatively those patients had 13 (43.3%) and the NDS group 2 (6.7%), indicating a significant difference for condyle head deformity between patients affected on DS and NDS before and after surgery. The score for JE was 1.1 ± 1.0 in the DS group and 0.6 ± 0.8 in the NDS group, a significant difference (P < 0.05).
Conclusion: As compared to the NDS, the DS in the present class III patients with FA showed a greater number of TMDs, such as condyle head deformity, disc displacement, and JE. It's important for surgeons and orthodontists to be aware of the possibility of TMDs on the DS in class III patients with FA when performing orthognathic surgery.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
