ABSTRACT

The Temporomandibular joint [TMJ] is the finest engineering of articulation in human body, working bilaterally and synchronously connecting cranium to the mandible facilitating open, close, gliding and hinge type of movement referred as Ginglymoarthrodial joint [or] craniomandibular articulation. The morphological development of the TMJ during prenatal life lags behind other joints in terms of both the timing of its formation and its development within the entire bony component. The condyle growth is very unique as it provides baseline for mandibular growth. In some individuals there is alteration in size & shape of condyle, due to congenital or trauma or local cause origin may affect morphology of the condyle causing loss functions of TMJ. These variations in the shape and size of condyle should be an important factor in diagnosis of TMJ disorders. The manifestation of developmental condylar malformation with normal functioning TMJ is rare and has not been documented in the literature. Hence we describe a unique case of morphological variations of the condyle as a contribution of rarities of TMJ structural variations. Background: One of the most important and unique joints in the body is the Temporomandibular Joint [TMJ]. It is a complex ginglymoarthrodial joint which work bilaterally and synchronously to perform essential functions like opening, closing of mouth and mastication to provide stability of mandibular position from dislocation from its functional position. The condylar shapes are categorized into five basic types: flattened, convex, angled, and rounded and concave.(1) Morphologic changes of condyle occur due to developmental variations, remodeling, trauma, endocrine disturbances, and malocclusion and radiation therapy. Methods: Diagnostic Observation. Conclusions: The variability in the shapes and sizes of condyle should be an important factor in diagnosing the disorders of temporomandibular joint.
