    Abstract:
    BACKGROUND: The treatment strategies for mandibular condylar head fractures, also known as intracapsular condylar fractures (ICFs), have not been concluded. We humbly present our treatment outcomes and share our experience in our department. AIMS AND OBJECTIVES: The aim of this study was to compare the functional outcomes between closed reduction (CR) and open reduction and internal fixation (ORIF) for management of unilateral or bilateral ICFs. MATERIALS AND METHODS: This 10-year retrospective cohort study included 71 patients with 102 ICFs who were treated in our department from May 2007 to August 2017. Nine patients mixed with extracapsular fractures were excluded; thus, 62 patients with 93 ICFs were included. All patients received treatment by the senior surgeon in Chang Gung Memorial Hospital, Linkou Branch, Taiwan. The patient's basic data, fracture morphologies, associated injuries, managements, complications, and maximal mouth opening (MMO) measurement at 1, 3, 6, and 12 months postoperative were reviewed for analysis. RESULTS: Among the 93 fractures, 31 (50%) were bilateral and 31 were unilateral (50%). Based on He's classification, 45 (48%) had type A fracture, 13 (14%) had type B, 5 (5%) had type C, 20 (22%) had type M, and 10 (11%) had no displacement. Maximal mouth opening of 37 mm in unilateral cases after 6 months was significantly higher than the 33-mm MMO in bilateral cases. In addition, the MMO in the ORIF group was significantly higher than that of the CR group in 3 months postoperative. Univariate (odds ratio, 4.92; P = 0.01) and multivariate (odds ratio, 4.76; P = 0.027) analyses revealed CR as an independent risk factor for trismus development compared with ORIF. Malocclusion was observed in 5 patients in both CR and ORIF groups. In addition, 1 patient developed temporomandibular joint osteoarthritis in the CR group. No surgical-related temporary or permanent facial nerve palsy was observed. CONCLUSIONS: Open reduction and internal fixation for condylar head fracture provided better recovery in MMO than CR, and the MMO recovery was less in bilateral condylar head fracture than unilateral condylar head fracture. Open reduction and internal fixation in ICFs have a lower risk for trismus development and should be the treatment of choice in selected cases.
