Temporomandibular joint alterations: two clinical case-reports of bifid condyle and temporomandibular joint ankylosis

Abstract

The etiology of alterations of the temporomandibular joint, such as ankylosis and bifid condyle, comprises several causes including trauma. However, otological infections cannot be overlooked as a probable cause of alterations of the temporomandibular joint, because the proximity between the external auditory canal and the temporomandibular joint facilitates the spread of infection in the region. This article presents a case-report of a patient with bifid condyle of the temporomandibular joint, in which the patient had no history of facial trauma, but had suffered recurrent otitis infections during her childhood. In parallel, a second case-report is described of temporomandibular joint ankylosis in a 12-year-old patient with a history of facial trauma during her childhood. The purpose of this study was to highlight and emphasize the importance of early diagnosis of temporomandibular joint disorders to avoid the development of facial asymmetries, restore function, esthetics, and the psychological state of the patient.

Kondylenhypoplasie: Klinischer Fall

“…Es wird als synoviales, bilaterales, voneinander abhängiges Gelenk mit eigenen Bewegungen definiert, jedoch gleichzeitig. Es ist auch das einzige im kephalen Skelett, das als dreiachsig eingestuft ist, dh es kann Bewegungen um drei Achsen ausführen (LIMONGI;MANZI und LIMONGI, 2019). Es besteht aus dem Kondylenprozess und der Gelenkhöhe des Schläfenbeins.…”

Condylar hypoplasia: Clinical case

“…The temporomandibular joint is one of the most complex joints in the human body (SHIVHARE et al, 2013), it is defined as a synovial, bilateral, interdependent joint, with its own movements, however simultaneous. It is also the only one in the cephalic skeleton classified as triaxial, that is, it is capable of performing movements around three axes (LIMONGI;MANZI and LIMONGI, 2019). It consists of the condylar process and the articular eminence of the temporal bone.…”

Hypoplasie condylienne: cas clinique

“…L'articulation temporo-mandibulaire est l'une des articulations les plus complexes du corps humain (SHIVHARE et al, 2013), elle se définit comme une articulation synoviale, bilatérale, interdépendante, avec ses propres mouvements, même simultanés. C'est aussi le seul du squelette céphalique classé comme triaxial, c'est-à-dire qu'il est capable d'effectuer des mouvements autour de trois axes (LIMONGI;MANZI et LIMONGI, 2019). Il se compose du processus condylien et de l'éminence articulaire de l'os temporal.…”

“…Au cours du développement embryonnaire, des modifications morphologiques et fonctionnelles peuvent survenir, telles qu'une hyperplasie et une hypoplasie condyliennes, des anomalies associées à des maladies ou syndromes spécifiques (dysostose de la mâchoire faciale ou syndrome du premier arc branchial), une ankylose, un condyle bifide, entre autres (LIMONGI;MANZI et LIMONGI, 2019).…”
