“…Traumatic TMJA is a serious temporomandibular joint disease, characterized by joint cavity occlusion, secondary intraarticular and periarticular bone abnormalities, intact joint cavity, condylar fracture caused by external forces, with or without joint capsule tears. [1] Ankylosis can lead to progressive limitation of mouth opening, which in turn can lead to speech and eating disorders, facial deformities, airway obstruction, and even psychological disorders. [2] It brings great pain to the patient and seriously reduces the quality of life of the patient.…”

Temporomandibular joint (TMJ) is a synovial joint composed of condyle, articular disc, temporal fossa and other structures. TMJ is prone to joint diseases due to its frequent activities and bite force. Temporomandibular joint ankylosis (TMJA) is a serious joint disease, which can lead to fibrous adhesion or bone adhesion within the joint, affect mandibular movement and cause facial deformity. Previous studies have shown that trauma, infection, systemic diseases and other causes can cause TMJA, among which trauma factors account for about 90%. The pathogenesis of traumatic TMJA is complex, treatment is difficult and there is a certain recurrence rate. However, the pathogenesis of traumatic TMJA has not been truly revealed, and animal model studies vary. In this article, the related factors and pathogenesis of traumatic TMJA were discussed.

“…Temporomandibular joint ankylosis is a clinical condition where the patient is unable to open the mouth due to the bony or fibrous union of the mandibular condyle with the glenoid fossa of the temporal bone. The etiology of it is varied and is mainly due to trauma or infection [1]. Clinical presentation varies at the time of involvement.…”

BackgroundTemporomandibular joint ankylosis is a severe debilitating clinical condition where there is fusion of the mandible with the temporal bone. It is often a challenge to the maxillofacial surgeon as the surgical treatment protocol must be tailored individually according to the time of presentation of the ankylosis, and proper postoperative aggressive physiotherapy must be advocated, which is essential for a successful outcome. This is a case series of six recurrent temporomandibular joint ankylosis, in which the historical Esmarch surgery was done, and the pterygomassetric sling was interposed between the osteotomized segments. Postoperative mouth opening and surgical outcome were satisfactory. In our cases, we created a pseudojoint, which was very successful using the Esmarch procedure. AimWe aim to improve mouth opening in patients presenting with temporomandibular joint reankylosis using the Esmarch procedure and evaluate the efficacy of the conventional and modified Esmarch procedure. Materials and methodsWe have included six cases of recurrent temporomandibular joint reankylosis. Five cases were operated on using the conventional Esmarch procedure in which the osteotomy was done at the angle region, below the inferior alveolar nerve canal, and one case using the modified Esmarch procedure, wherein the osteotomy was done above the inferior alveolar nerve canal. The patients included in the case series presented with temporomandibular joint reankylosis and had undergone multiple surgeries for the release of ankylosis. ResultsSatisfactory postoperative mouth opening was achieved in all six patients. It was observed that in the modified Esmarch osteotomy, where the cuts were placed above the inferior alveolar nerve canal, there was a massive hemorrhage intraoperatively. This was primarily attributed to the altered anatomy of the maxillary artery, which was very close to the ankylotic mass. When the osteotomy was done below the inferior alveolar nerve canal, it was found that by this technique, the intraoperative hemorrhage was minimal, but it carries a risk of postoperative inferior alveolar nerve paresthesia, which was managed conservatively. ConclusionWith the abovementioned results, we proceeded with the conventional Esmarch procedure for five cases and the modified Esmarch procedure for one case. It was found that in temporomandibular joint reankylosis cases, where there is extensive ankylotic mass extending from the glenoid fossa to the coronoid process of the mandible, this Esmarch procedure provides promising results when the osteotomy cuts are placed below the nerve canal.

Ankylosis of TMJ is a disorder in which a stiff joint makes the mouth opening restricted. The restriction of mouth opening is mostly due to union between the condylar head and the glenoid foss of temporal bone. The most common etiology for this ankylosis is trauma. The other causes include local and systemic infections, inflammations, neoplasms, previous TMJ surgeries and congenital syndromes. This ankylosis alters the entire life style of the affected person because of its additional clinical presentations like speech, chewing, facial appearance disfigurements. If affected in the growth phase during early childhood, it may lead to deformations in the mandibular growth leading to facial asymmetry. Hence, early diagnosis and surgical intervention are of critical importance in the management of TMJ ankylosis. The surgical therapy usually aims to achieve joint movement with optimal mouth opening and without any recurrences. Joint reconstruction, interpositional arthroplasty and gap arthroplasty are the three main surgical treatment options. Inspite of availability of various alloplastic and autogenous graft materials, interpositioning of the temporalis muscle flap to the joint space offers specific advantages like ease of harvesting, comparatively less morbidity of donor site, and adequate coverage of surgical site. The efficiency and efficacy of this temporalis muscle flap is highlighted in the present case report of surgical management of unilateral TMJ ankylosis.
