Review
Ankylosis of the temporomandibular joint is defined as a permanent constriction of the jaws with less than 30mm mouth opening measured between the incisors, occurring because of bony, fibrous or fibro-osseous fusion. Resulting complications such as speech, chewing, swallowing impediment and deficient oral hygiene may occur. The overall incidence is decreasing but remains significant in some developing countries. The most frequent etiology in developed countries is the post-traumatic ankylosis occurring after condylar fracture. Other causes may be found: infection (decreasing since the advent of antibiotics), inflammation (rheumatoid arthritis and ankylosing spondylitis mainly) and congenital diseases (very rare). Management relies on surgery: resection of the ankylosis block in combination with bilateral coronoidectomy… The block resection may be offset by the interposition temporal fascia flap, a costochondral graft or a TMJ prosthesis according to the loss of height and to the impact on dental occlusion. Postoperative rehabilitation is essential and has to be started early, to be intense and prolonged. Poor rehabilitation is the main cause of ankylosis recurrence.

PURPOSE
Extra-articular temporomandibular bony ankylosis between the zygomatic bone and coronoid process is a rare condition. Currently, there are fewer than 40 cases reported in the English-language literature. The aim of this study was to report a case of zygomatico-coronoid ankylosis with surgical intervention and a literature review.
MATERIALS AND METHODS
Through a PubMed search from 1946 to February 2018, using the terms ("extra-capsular" OR "zygomatico-coronoid" OR "extra-articular") AND ("ankylosis"), 61 articles were initially identified. After screening, manual reviewing, and including additional articles through reviews of the reference lists, 26 reports (33 patients) were included in the analysis.
RESULTS
Patients' age ranged from 12 to 71 years (mean, 36.62 yr; standard deviation, 16.24 yr). The gender composition of patients was male (n = 20; 60.6%), female (n = 12; 36.4%), and unknown (n = 1; 0.3%), with a clear male predominance. The etiologies were trauma (n = 25; 75.8%), infection (n = 3; 9.1%), surgical complication (n = 4; 12.1%), and radiotherapy for maxillary cancer (squamous cell carcinoma; n = 1; 3.0%). The treatment options were surgical intervention through an intraoral approach (n = 19; 57.6%), an extraoral approach (n = 10; 30.3%), and intraoral and extraoral approaches (n = 2; 6.1%) and nonsurgical intervention (n = 2; 6.1%).
CONCLUSION
Zygomatico-coronoid ankylosis is a possible cause of mouth-opening limitation, particularly in relation to facial trauma. However, it can be easily overlooked because of the rarity of zygomatico-coronoid ankylosis and the attention focused on the joint. Surgical intervention is regarded as a good treatment to improve mouth-opening limitation.

Meta-Analysis Review
Temporomandibular joint ankylosis is defined as bony or fibrous adhesion of the anatomic joint components accompanied by a limitation in opening the mouth, causing difficulties with mastication, speaking and oral hygiene as well as inadvertently influencing mandibular growth. Surgical treatment procedures include arthroplasty of the joint cavity with or without a reconstruction and a coronoidectomy, an autogenous costochondral rib graft, distraction osteogenesis and intensive mouth-opening exercise, corrective orthognathic surgery or alloplastic joint prostheses. The authors of this study would like to provide the reader with an evidence-based review of the literature in order to determine the most efficient way to manage TMJ ankylosis and re-ankylosis. The authors have concluded that in order to achieve a satisfactory and durable effective treatment, an individualized approach is necessary in each case.

Review
The authors review the literature about the different etiopathogenetic hypotheses of tooth ankylosis. They classified the ankylosis in three big groups: traumatic ankylosis due to direct and indirect injuries to the tooth, iatrogenic ankylosis due to unadvised maneuvers made by the dentist, and atraumatic ankylosis. The last is the most important group caused by metabolic problems and with family characteristics. Furthermore they underline the important role played by GAG and corresponding lytic enzymes in the development of atraumatic ankylosis. They described, the therapeutical procedures to be used in the different cases. The clinical cases presented are representative of the different therapeutical approaches.

Review
A case report describing an ankylosed permanent maxillary canine which was brought into the arch by a combination of surgery and orthodontics is used as a basis to review the literature concerning many aspects of the management of ankylosed permanent teeth. The literature indicates surgical luxation is a two edged sword, that is, it may cause ankylosis if used with surgical exposures but it can also be the only means of treating ankylosis. The treatment of the canine which is the subject of this case report resulted in damage to the tooth. Vanarsdall's recent contributions in this field are detailed.

Ankylosis forming between the zygomatic arch and the coronoid process is a rarely encountered pathological extracapsular ankylosis. Its treatment protocol consists of surgical removal of the coronoid process with the ankylotic mass and jaw opening-closing exercises after surgery. Myositis ossificans (MO) is a self-limiting, benign ossifying lesion. It affects all types of soft tissues including subcutaneous adipose tissue, muscles, tendons and nerves. It is most frequently found in the muscle as a solitary lesion. The clinical appearance of MO is generally in the form of a mass characterized with an ossified soft tissue. When it develops alone, cross-sectional imaging might not be specific, and it may appear similar to worse etiologies. It is suggested multiple imaging modalities should be used in the assessment of a suspicious soft tissue mass. MO is a benign self-limiting disease. In this case report, in the radiographic examination of a 41-year-old female patient, ankylosis between the left coronoid process and the zygomatic bone accompanied by possible MO in the left medial pterygoid muscle was observed. Resection of the coronoid process with the ipsilateral route, resection of the ankylotic mass with the hemicoronal approach and resection of the contralateral coronoid process with the intraoral approach were performed, but the ossified formation in the medial pterygoid muscle was not touched.

Meta-Analysis Review
Comparison of surgical outcomes related to interpositional arthroplasty materials used in patients with temporomandibular joint ankylosis: a systematic review and meta-analysis.
Surgical management of temporomandibular joint (TMJ) ankylosis involves various techniques from which interpositional arthroplasty (IPA) involves using several materials. The objectives of this study were to assess and compare post arthroplasty maximum mouth opening (MMO), symptoms like pain and discomfort in jaw opening and movements, failures such as reankylosis, neurosensory disturbances, and the effect of confounding variables such as age, gender, physiotherapy, etc. The search (conducted in September, 2021) included studies published in English on otherwise healthy individuals (11 months to 88 years) having undergone arthroplasty with a minimum of six months' follow up. We used search engines such as Cochrane database, PubMed, Embase, Scopus, EBSCO host, Pro quest, J gate, Google Scholar, and manual search to include books and grey literature. Randomised clinical (RCT) and non-randomised clinical trials, observational studies, case series and reports meeting the inclusion criteria were selected. Two reviewers (HD and NP) independently extracted the data. Risk of bias was assessed using the Cochrane tool, Rangel checklist, and Joanna Briggs Institute. Data were analysed using RevMan (Version 5.4). Fifty studies with 1524 participants (442 bilateral and 891 unilateral joints) were included; six RCTs, 31 retrospective, 10 prospective, and three case series and reports. Amongst all interpositional materials, the highest increase in mouth opening was seen with dermis fat graft with a mean difference (Pooled MD) being 35.29mm (95% CI [32.36 to 38.22]). Comparison of temporalis myofascial with gap arthroplasty (GA) showed significant increase in MMO (Pooled MD in mm 1.30 95% CI [0.14 to 2.45]). Recurrence was significantly reduced when (IPA) was used, compared with GA (Risk difference 0.08mm 95% CI [-0.15 to -0.02]) and for Temporalis Myofascial Flap (TMF) when compared with GA (Risk difference -0.07mm 95% CI [-0.15 to 0]). Higher odds for developing neurosensory disturbances were seen with Al-Kayat Bramley incision (Pooled OR 0.11 95% CI [0.04 to 0.34]) compared to pre-auricular incision (Pooled OR 0.03 95% CI [0.01 to 0.09]). IPA was superior to GA with respect to maximum mouth opening (MMO) (Pooled MD in mm 1.21 95% CI [0.41 to 2.07]). Dermis fat graft offers the highest MMO. The overall quality of evidence for RCTs is poor while that of observational studies is moderate as per the relevant assessment of quality of evidence. More research with appropriate study designs is needed. Similar to the findings from the previous reviews, outcomes with IPA were superior when compared to GA in terms of mouth opening and less recurrence.

Review
BACKGROUND
Dentoalveolar ankylosis in growing patients is complex leading to continuing root replacement resorption, tooth infra-position, or may even affect the development of alveolar ridge and adjacent teeth. While extraction of ankylosed teeth might be associated with bone loss, decoronation of the offending tooth (removal of crown portion and instrumentation of pulp canal to stimulate bleeding) has been suggested as a more conservative approach of bone preservation until definitive implant placement is planned.
OBJECTIVE
To primarily assess the efficacy of bone width and height preservation around ankylosed permanent teeth following decoronation.
METHODS
Pubmed, Embase, Ovid Medline, Thomson's ISI Web of Science and Cochrane library were searched from the year 1984 up to May 2015. Two authors conducted the data extraction. To eliminate publication bias, Open Grey literature and Pro-quest Dissertation Abstracts and Thesis database was also consulted.
RESULTS
Through our strict selection criteria, only 12 articles were considered for eligibility. No randomized controlled trials were identified. Only one retrospective cohort study, four case series and seven case reports, were analyzed.
CONCLUSIONS
Following decoronation, preservation of ridge height and ridge width were both noted. To maximize the benefits of decoronation, a timely and wellmonitored intervention is required. Treatment in patients, who have surpassed pubertal growth peaks, may not yield maximum effective treatment outcomes.

Ankylosis of the temporomandibular joint (TMJ) is a joint stiffness with an oral aperture of less than 30 mm measured between the incisors, occurring because of a bony, fibrous or fibro-osseous fusion. Arthrosis is a rare cause of the ankylosis of the temporomandibular joint. We report a case of ankylosis of the TMJ due to osteoarthrosis, in order to highlight the diagnostic and therapeutic features of this quite uncommon disease.
