Temporomandibular condylar osteochondromas: characteristics and complications

DiscussionRadiographically, 2-D imaging is adequate to establish an initial radiographic diagnosis. However, more advanced modalities (computed tomography/magnetic resonance imaging [CT/MRI) are indicated to better evaluate the orientation of the tumor and assist in the surgical management. The 3-D imaging of the 3 cases presented here emphasize this point. Positron emission tomography/fluorodeoxyglucose (PET/FDG) imaging has also been recommended for specific cases. MRI may overestimate tumor aggressiveness secondary to the influence of bone marrow and soft tissue edema. The recognition of an osteochondroma is significant because it is benign, but it can lead to disfigurement and loss or altered mandibular function, if not treated.

CONCLUSIONS: The pathological alterations verified in these arthropathies involved diseases that were predominantly proliferative, i.e., unilateral condylar hyperplasia, osteochondroma and synovial chondromatosis of the tumor or pseudotumor type and bony ankylosis associated with callus formation of the reparative type, and less frequent degenerative changes for which the disease is so named.

We present an extremely rare case of OS of the mandibular condyle in a 52-year-old male patient who presented to our hospital with gradual deviation of the lower jaw, difficulty in opening the mouth and chewing the food for 20 years with clinicoradiological and pathological correlation.

ConclusionsMandibular asymmetry is the fulcrum of many debates among orthodontists and maxillofacial surgeons and is correlated to the development of temporomandibular joint (TMJ) symptoms and temporomandibular disorders (TMDs). The importance of early diagnosis of progressive causative conditions is essential.

Synovial osteochondromatosis (SO) of the temporomandibular joint (TMJ) is a rare benign disorder characterized by the development of multiple osteocartilaginous nodules in the synovial membrane, which subsequently detach, turning into loose bodies. A 48-year-old man sought dental care for pain and swelling affecting the left TMJ. The clinical features and imaging findings suggested a diagnosis of SO. After surgical procedures, macroscopically, 208 loose bodies were observed, ranging from 1.7 to 7.5  cm in diameter; on microscopy, they appeared as circumscribed osteocartilaginous nodules, partly ossified, consistent ...

Publication date: Available online 1 July 2017Source: Journal of Oral Biology and Craniofacial ResearchAuthor(s): Vikas Meshram, Natarajan C., Jayant Landge, Sayali JadhavAbstractRadiolucent lesions of Temporomandibular Joint (TMJ) represent a diagnostic challenge and a treatment conundrum. Biopsy of the lesions is technically difficult owing to their complex anatomy. The Differential Diagnosis (DD) includes a wide array of lesions including Simple Bone Cyst, Ameloblastoma, Central Giant Cell Granuloma, Hemangioma, Osteoblastoma, Osteochondroma, Chondroblastoma, Chondrosarcoma, Neurofibroma and metastatic malignant lesions...

To evaluate the feasibility of the orthodontic traction after local resection of the condylar osteochondroma (OC). From November 2011 to September 2016, consecutive patients with condylar OC who underwent orthodontic extraction after local resection of the mass were reviewed. Clinical data and cone-beam computed tomography (CT) were obtained before treatment (T0), 1 week after surgery (T1), and at least 6-month follow-up after OC resection (T2). Repeated-measures analysis of variance with Bonferroni multiple-comparison test was used to compare the 3-dimensional cephalometric variables at different time points and the pair...

We report the outcomes of 12 patients with osteochondroma of the mandibular condyle who were treated by condylectomy with sagittal split ramus osteotomy (SSRO) between January 2011 and October 2015. Variables assessed before and after operation were imaging, appearance, maximum mouth opening, maximum mandibular protrusion, lateral excursion, and function of the temporomandibular joint (TMJ). Patients were followed up for a mean (range) of 21 (13 - 30) months. Outcomes were satisfactory with no complications or recurrence. Patients regained good occlusion and facial symmetry, and satisfactory function of the TMJ. Our result...

Authors: Kwon YE, Choi KS, An CH, Choi SY, Lee JS, An SY Abstract A 21-year-old woman presented with facial asymmetry. Crepitus and clicking of the temporomandibular joint were noted. The midline deviated 5.5 mm to the left, and secondary malocclusion was observed. Panoramic and cone-beam computed tomographic images showed an irregular and exophytic bony mass on the anteromedial surface of the right mandibular condyle. A 3-phase bone scan revealed increased tracer uptake on the affected side. The lesion was treated with excision and reshaping under the diagnosis of osteochondroma confirmed by a histopathological ex...

Referred otalgia is sometimes misdiagnosed as tension headache or migraine. Clinicians can easily overlook these disorders, and request unnecessary and expensive investigations. Secondary otalgia caused by osteochondroma of the temporomandibular joint (TMJ) can be a difficult to diagnose for even experienced oral and maxillofacial (OMF) surgeons.
