Development of temporomandibular ankylosis after diagnosis of Jacob’s disease: clinical and tomographic assessment

Jacob's disease is a rare condition that consists of the formation of a pseudo joint structure between the mandibular coronoid process and the zygomatic bone, resulting in limited mouth opening. The disease is difficult to diagnose and etiology is uncertain. This article describes a clinical case of a 6-year-old child with limited mouth opening, which resulted in the formation of a temporomandibular ankylosis leading to complete immobility due to delayed diagnosis and treatment of the disease. A review of this pathology and the most precise imaging exams are discussed for the early and differential diagnosis of the disease.

The aim of this study was to evaluate treatment with dry needling (AS) in the masseter muscle of patients diagnosed with myofascial pain as the pain symptoms and the mouth opening (AB). After sample size calculation, we selected 10 patients referred for treatment of temporomandibular disorders (TMD) diagnosed with MP, with or without limited mouth opening according to Axis I of the RDC/TMD, who underwent six DN sessions, once a week. Pain measurement using the Visual Analogue Scale (VAS) and an evaluation of the extent of mouth opening were done. All participants were female and the average age was 39.2 years, with 8 (80%) having a diagnosis of myofascial pain with limited mouth opening and 2 (20%) with only myofascial pain. Maximum unaided opening without pain before treatment was 31.9 mm and went to 36.2 mm, and the maximum unaided opening went from 39.6 mm to 43.1 mm. In both, however, could not find statistical significance (p> 0.05). Regarding the mean weekly VAS value, this went from 8.3 before treatment to 2.3 a week later, with statistically significant results (p < 0.05). In this study, the AS in the masseter muscle presented is a therapeutic alternative in the treatment of myofascial pain.

Joint Ankylosis

Pseudoankylosis is a rare condition that causes inability to open the mouth due to condition related to outside of the temporomandibular joint. Most literature refers to this hypomobility disorder, a result of fusion of the zygomatic bone to the coronoid process, and very rarely is insidious coronoid hyperplasia causing mechanical interference with the posterior maxilla has been reported. We present a case of a 45-year-old woman, who presented with coronoid malformation and overgrowth resulting in progressive decrease in mouth opening. She was managed with coronoidectomy, following which good mouth opening was obtained. In this paper we discuss about the diagnosis and management of this rare disorder.

Reported Data

Objective: This systematic review aimed to compare outcomes between ultrasound (US)-guided arthrocentesis and conventional arthrocentesis for the management of temporomandibular joint disorders (TMDs). Methods: PubMed, MEDLINE, Cochrane Library, Google Scholar and th EBSCOhost databases were searched up to 30 September 2020 for randomized control trials (RCTs) comparing US-guided and conventional arthrocentesis. The review protocol followed the PRISMA guidelines and was registered in PROSPERO (CRD42020211942). The risk of bias of the studies was independently evaluated using Cochrane Risk of Bias tool. Results: Four RCTs were included. It did not demonstrate any statistically signicant difference in pain or maximal mouth opening (MMO) scores after 1 week and 1 month of follow-up between US-guided and conventional arthrocentesis. Studies also reported data on intra-operative needle relocations and operating time but with conicting results. Conclusion: This study indicates that the use of US during arthrocentesis may not improve postoperative pain and MMO in the short term. Further high-quality adequately powered RCTs are required to strengthen current evidence.

The surgical management of paediatric patients with temporomandibular joint (TMJ) ankylosis, mandibular retrognathia and obstructive sleep apnoea (OSA) is challenging. We report a nine-year-old boy who presented to the Department of Oral Health, Sultan Qaboos University Hospital, Muscat, Oman, in 2016 with complaints of limited mouth opening, loud snoring and excessive daytime sleepiness. He was diagnosed with TMJ ankylosis, mandibular retrognathia and severe OSA. The patient initially underwent mandibular distraction and, subsequently, release of the TMJ ankylosis and rib graft reconstruction. The overall patient outcome was successful, with improvement in OSA-related symptoms, good facial symmetry and adequate mouth opening.Keywords: Temporomandibular Joint Disorders; Temporomandibular Ankylosis; Retrognathia; Obstructive Sleep Apnea; Case Report; Oman.

Intermittent open-mouth locking related to disorders of the temporomandibular joint are not uncommon. As a result of joint laxity, the mandible shifts to one side. The coronoid process then becomes locked lateral to the zygomatic arch. These patients present with the mouth opened and an inability to close the mouth. This article describes a case of intermittent open-mouth mandibular locking in a cat and a modified surgical treatment combining zygomatic arch and coronoid process reduction.

The Mean

Arthrocentesis in temporomandibular joint disorders can be associated with the intra-articular infiltration of various drugs with the objective of increase treatment efficacy. The aim of this study was to evaluate the clinical indexes variation in patients affected by temporomandibular joint disorders treated with arthrocentesis and sodium hyaluronate (SH) injections. A total of 28 patients suffering from temporomandibular joint disorders underwent one cycle of five arthrocentesis and infiltrations of sodium hyaluronate. Spontaneous mouth opening improved from 36.3 ± 7.5 mm to 45.1 ± 1.9 mm at six months follow-up. A significant reduction in the pain at rest and during mastication mean values emerged at follow-up (p < 0.0001). The mean masticatory efficiency, evaluated through a visual analogic scale, showed improvement at the follow-up period, highlighted by the increase of mean value from a baseline of 3.1 ± 1.2 to a mean value of 8.5 ± 1.2 (p < 0.0001). The mean severity of the joint damage at baseline time was 2.4 ± 0.9 and decreased to 0.4 ± 0.3 at the end of the follow-up period. The decrease in values is confirmed by statistical test (p < 0.05). Our data show how arthrocentesis integrated with sodium hyaluronate infiltrations performed under local anesthesia is a valid method of treating temporomandibular joint disorders.

Proper Diagnosis

ABSTRACT Coronoid Process Hyperplasia is a rare condition characterized by the increase in size of a histologically normal bone. It can be confused with Temporomandibular Joint Dysfunction, due to the presence of major signs/symptoms, including the limitation of mouth opening, pain, and facial asymmetry. Although several theories have been proposed, the etiology remains unknown. The recommended treatment is mandibular coronoidectomy. In the present study, the importance of computed tomography to reach the proper diagnosis and the surgical treatment plan is demonstrated.
