Use of Oral Mucoperiosteal and Pterygo‑Masseteric Muscle Flaps as Interposition Material in Surgery of Temporomandibular Joint Ankylosis: A Comparative Study


Anyanechi CE, Osunde OD* and Bassey GO

Background: The most common complication of surgery for the release of temporomandibular joint (TMJ) ankylosis is relapse of the ankylosis. To prevent reâÂ??Â??ankylosis, a variety of interpositional materials have been used. Aim: The aim was to compare the surgical outcome of oral mucoperiosteal flap, not hitherto used as interpositional material, with pterygoâÂ??Â??masseteric muscles flap after surgical release of TMJ ankylosis. Subjects and Methods: This was a prospective randomized study of all consecutive patients treated for the release of complete TMJ bony ankylosis, from January 2003 to December 2012, at the Oral and Maxillofacial unit of our institution. The patients were randomized into two groups: The pterygoâÂ??Â??masseteric group comprises 22 patients while the oral mucoperiosteal group had 23 patients. Information on demographics, clinical characteristics, and postoperative complications over a 5 year followâÂ??Â??up period were obtained, and analyzed using the statistical package for social sciences (Statistical Package for the Social Sciences version 13, Chicago, IL, USA). A P < 0.05 was considered significant. Results: The age of the patients ranged from 15 to 28 mean 20.3 (3.35) years while the duration of ankylosis ranged from 2 to 16 mean 5.1 (3.4) years. The baseline demographic (gender; P = 0.92; side; P = 0.58) and clinical characteristics in terms of etiology (P = 0.60) and age (P = 0.52) were comparable in both treatment groups. All the patients presented with complete bony TMJ ankylosis with a preoperative interâÂ??Â??incisal distance of <0.5 cm. The intraoperative mouth opening achieved ranged from 4 cm to 5 cm, mean 4.6 (0.27) cm and this was not different for either group (P = 0.51). The patients were followed up postoperatively for a period ranging from 3 to 5 years, mean 3.4 (0.62) years. The mouth opening decreased, over the period of postoperative review, from the initial range of 4–5 cm to 2.9–3.6 cm, and this was not different in both groups (P = 0.18). Conclusion: This study suggests that oral mucoperiosteal flap could be an option in the choice of interpositional materials in surgery of TMJ ankylosis.
