Aim: Temporomandibular joint (TMJ) ankylosis is an extremely disabling affliction that causes problems in mastication, digestion, speech, appearance and hygiene. Surgery of TMJ ankylosis needs careful evaluation and planning to yield predictable results. Temporomandibular joint ankylosis is very common among young children. The aim of treatment is not only to treat the movement of the joint but also to prevent relapse.
Materials And Method: In this series, 18 cases of temporomandibular joint ankylosis were treated at our institute from January 2012 to January 2017 with osteoarthrectomy and interpositional arthroplasty. Patients were in the age range of 5-57 years, with 11 males and 7 females and including 8 unilateral and 10 bilateral cases. Duration of ankylosis ranged from less than 2 years to more than 6 years. Seven of the patients were secondarily taken up for correction of their deformities with either orthognathic surgery or distraction osteogenesis.
Results: Good mouth opening was achieved in all the patients with a mean follow-up period of 12 months. The early post-operative mouth opening ranged from 24 to 37 mm. The late post-operative mouth opening ranged from 20 to 33 mm. There was a stress on aggressive physiotherapy for a minimum of 6 months in all our patients.
Conclusion: Interpositional arthroplasty using vascularized temporalis fascia flap is a very reliable method to prevent recurrence of ankylosis, and it also avoids the disadvantages of alloplastic materials as well as nonvascularized autogenous tissues.

Introduction: Temporomandibular joint ankylosis is defined as permanent jaw constriction with an interincisal mouth opening of less than 30 mm, due to bony, fibro-osseous or fibrous fusion. Ankylosis may be uni- or bilateral. The complications of this ankylosis affect the functions of mastication, swallowing and phonation, sometimes facial morphology, and disturb dental hygiene.

Introduction: Restricted mouth opening has major health implications, such as malnutrition, difficulty in speech, and poor oral hygiene resulting in a functional shortage of the masticatory system. Reduced mouth opening can occur due to trismus, as in the oral submucous fibrosis (OSMF) condition. Excision of fibrous bands in OSMF leads to reestablishment of the mouth opening.

Case Summary: A 1-year-old spayed female domestic British Shorthair cat was presented for facial trauma; there were multiple mandibular fractures involving the right temporomandibular joint (TMJ) that were managed conservatively. After 2 months, the owner reported a gradual onset of the cat's inability to open its mouth and subsequent inappetence. The maximum mouth opening (MMO) measured 7 mm.

Background: This study aimed to compare the different outcomes of mandibular distraction osteogenesis (MDO) using computer-aided design and manufacturing (CAD/CAM) surgical guides accompanied by pre-bent distractors versus CAD/CAM surgical guides with commercial distractors.
Methods: Twenty-eight patients with severe dentofacial deformities secondary to unilateral temporomandibular joint ankylosis (TMJA) were retrospectively enrolled. Ten parameters associated with MDO were measured preoperatively, virtually, and postoperatively.
