“…The mandible is a bone belonging to the viscerocranium, the only mobile bone of the skull. Structurally, it is made up of two components: the mandibular body and the mandibular ramus, each with different anatomical characteristics and repairs that fulfill fundamental roles, such as providing articulation to the lower teeth, in addition to allowing the passage of neurovascular structures of importance for the oral and dental region [1][2][3]. In the branch of the mandible are the coronoid and condylar processes; the latter acts as an articular component within the mandible, which allows it to articulate with the mandibular fossa of the temporal bone, thus forming the temporomandibular joint (TMJ).…”

Objective: The aim of this study was to describe the prevalence of anatomical variants in the bifid mandibular condyle (BMC) and report its association with temporomandibular joint (TMJ) pathology. Methods: We searched the Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS databases from their inception up to September 2023. Two authors independently performed the search, study selection, and data extraction, and they also assessed the methodological quality with an assurance tool for anatomical studies (AQUA). Finally, the pooled prevalence was estimated using a random effects model. Results: A total of 50 studies met the eligibility criteria. Twenty studies, with a total of 88,625 subjects, were included in the meta-analysis. The overall prevalence of the bifid mandibular condyle (BMC) variant was 1% (95% CI = 1% to 2%). Conclusions: The correlation between the BMC and TMJ pathologies has a relatively low prevalence in studies that present a considerable number of subjects. From a clinical point of view, a direct association cannot be made between the presence of the BMC and TMJ pathologies or symptoms.

Resumen: Objetivo: El cóndilo mandibular bífido es una alteración morfológica de la articulación temporomandibular en la que el cóndilo presenta un surco en la superficie superior que genera dos cabezas condilares. Esta alteración puede ser unilateral o bilateral. La mayoría de los cóndilos mandibulares bífidos se detectan mediante radiografías panorámicas, sin embargo, la tomografía computarizada Cone Beam de articulación temporomandibular es considerado el examen de elección para el diagnóstico de esta alteración. El propósito de este trabajo es presentar un caso de cóndilo mandibular bífido bilateral detectado incidentalmente mediante una tomografía computarizada Cone Beam solicitada por un diagnóstico presuntivo de osteoartritis. Caso clínico: Una paciente de 22 años sin antecedentes de traumatismos cráneo faciales solicita una tomografía computarizada Cone Beam de articulaciones temporomandibulares por diagnóstico presuntivo de osteoartritis. En la exploración del volumen se encontraron cóndilos mandibulares bífidos con dos cabezas condilares, medial y lateral de forma bilateral, siendo más acentuado en el cóndilo derecho. Palabras claves: Articulación temporomandibular, cóndilo bífido mandibular, tomografía computarizada. // Abstract: Aim: The bifid mandibular condyle is a morphological alteration of the temporomandibular joint in which the condyle has a groove on its upper surface that generates two condylar heads. This alteration can be unilateral or bilateral. Most bifid mandibular condyles are detected by panoramic radiographs, however, Cone Beam computed tomography of the temporomandibular joint is considered the test of choice for the diagnosis of this alteration. The purpose of this work is to present a case of bilateral bifid mandibular condyle, incidentally detected by Cone Beam computed tomography requested for a presumptive diagnosis of osteoarthritis. Clinical case: A 22-year old female patient with no history of craniofacial trauma requests a Cone Beam computed tomography of the temporomandibular joints due to a presumptive diagnosis of osteoarthritis. In the volume exploration, bifid mandibular condyles were found with two condylar heads, medial and lateral bilaterally, being more accentuated in the right condyle. Key words: Computed tomography, mandibular bifid condyle, temporomandibular joint.
