Temporomandibular joint (TMJ) ankylosis is defined as osseous or fibrous fusion of the condyle of the mandible and the mandibular fossa of temporal bone (Nitzan et. al. 1998).It is a debilitating disease that renders the afflicted person unable to use their oral cavity well. Clinical presentation depends on the age at which ankylosis occurs and whether ankylosis is unilateral or bilateral. Surgery and postoperative physiotherapy are regarded as the mainstay treatment for TMJ ankylosis. The study reviews surgical outcomes of 13 children treated for temporomandibular joint (TMJ) ankylosis in the maxillofacial and oral surgery unit at Red Cross Children's Hospital. Nine patients were treated by gap arthroplasty, while four patients had previous reconstruction with costochondral graft. One patient treated by gap arthroplasty reankylosed. The study showed a positive correlation between intraoperative MIO and the outcome, and between age and the outcome. Mouth opening was improved by 15mm, with postoperative change of-4mm.

“…[18] Close anatomical inter-relation between the middle ear and the TMJ create a reciprocal affection. Middle ear infection as otitis media was reported long time ago as an etiological factor for TMJ ankylosis [19,20]. Bony ankylosis usually disturbs the anatomy due to exorbitant bone formation, it might extend to involve structures of the temporal bone; this abnormal bone formation may encroach on the tympanic plate, hence disturbed volumetric anatomy and decrease middle ear volume are induced.…”

Abstract:Objective: This study was designed to evaluate the effect of temporomandibular joint (TMJ) bony ankylosis on Eustachian tube (ET) functions. Subjects and Methods: Twelve patients suffering from TMJ bony ankylosis were selected from those attending the out-patient Clinic of Oral and Maxillofacial Surgery Department, Faculty of Oral and Dental Medicine, Cairo University. Twelve subjects (control group) underwent Eustachian tube function test were selected also. Tympanometry was utilized to assess Eustachian tube function. Three pressure reading (P1, P2, and P3) of the middle ear and external ear canal volume were recorded by the use of tympanometry. Comparisons were performed between patient and control group to evaluate the change of pressure. Results: Throughout the results, four ears showed type (C) tympanogram representing Eustachian tube dysfunction, two ears showed type (B) tympanogram which represent otitis media with effusion. While other ears showed type (A) tympanogram. On comparing the pressure values between the patients and the control, significant decrease was recorded in (P2) value in the patients group and no significant difference existed in the external canal volume. Conclusions: The Eustachian tube function is affected in patients of temporomandibular joint bony ankylosis, it cannot adapt to changes in pressure effectively. Patients of TMJ ankylosis are more liable to develop otitis media. Inflation-deflation test is a reliable method for evaluating Eustachian tube function in patients of (TMJ) ankylosis. The external ear canal volume was not affected in this group of patients.

The objective of this study is to describe the complication of temporomandibular joint (TMJ) ankylosis consequent to otitis media. The method applied is prospective case series and data collection done in tertiary referral centre from April 2012 to April 2013. Case description of three adolescent male patients with unilateral TMJ ankylosis consequent to ipsilateral chronic suppurative otitis media. Further literature review of TMJ ankylosis in relation to otitis media for evaluation for predisposing conditions. Surgical treatment by ipsilateral canal wall down mastoidectomy and concurrent TMJ gap arthroplasty. Surgical exposure confirmed ipsilateral bony ankylosis in all three. Two cases with long standing trismus had developed contralateral disuse fibrous ankylosis and required bilateral gap arthroplasty. Relief of trismus achieved in all three cases. Literature review indicated three similar cases secondary to otitis media. A universal feature among all previous case reports and the current case series was the age at onset of trismus, being at 10 years or less in all. TMJ ankylosis is a rare but potential complication of paediatric ear suppuration. Dehiscence along the tympanosquamosal fissure, tympanic plate and the foraminae of Huschke and Santorini in the paediatric population may predispose to extension of tympanic suppuration to the TMJ.
