Abstract:
Objective:To evaluate the clinical effect of temporomandibular joint disc anchoring and deviated jaw splint in the treatment of adolescent patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint.Methods:A total of 30 patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint who were treated in the Suzhou Municipal Hospital from January 2020 to March 2023 were prospectively selected. Among them, 10 patients in the surgical splint group received temporomandibular joint disc anchoring combined with sequential treatment of deviated jaw splint; 20 patients in the splint group received deviated jaw splint treatment. The improvement of facial deviation before and after treatment was compared between the two groups, and magnetic resonance imaging (MRI) was used to evaluate the stability of temporomandibular joint disc position and the change of condylar height.Results:After treatment, the midfacial line deviation was (1.3±0.3)mm and the condylar height was (21.5±0.6)mm in the surgical splint group; in the splint group, the midfacial line deviation was (1.5±0.4)mm and the condylar height was (21.6±0.7)mm. Both facial deviation and condylar height in the two groups were significantly improved compared with those before treatment (all P<0.01). During the treatment course, MRI was taken every 3 months in both groups. The stability rate of the joint disc in the surgical splint group was 100%(10/10), and that in the splint group was 90.0%(18/20). Conclusions:The application of temporomandibular joint disc anchoring combined with sequential treatment of deviated jaw splint in adolescent patients with mandibular deviation deformity complicated with anterior disc displacement of temporomandibular joint can achieve good clinical effects. The position of the temporomandibular joint disc remains stable before and after treatment, and new bone formation occurs in the condyle.
