Otomandibular syndrome

Otomandibular syndrome, also known as otomandibular dysostosis, is a rare congenital condition characterized by malformations affecting the ears and the mandible (lower jaw). This condition falls within the spectrum of craniofacial anomalies involving structures derived from the first and second branchial arches. Key clinical features include microtia or anotia (underdevelopment or absence of the external ear), conductive hearing loss, mandibular hypoplasia (underdevelopment of the lower jaw), and facial asymmetry. Additional features may include preauricular tags, middle ear anomalies, and temporomandibular joint abnormalities. The severity of the condition can vary considerably between affected individuals. The body systems primarily affected are the craniofacial skeleton, the external and middle ear structures, and the associated soft tissues of the face. Some patients may also present with associated anomalies such as lateral facial clefts or other branchial arch-derived structural defects. The condition is typically apparent at birth due to the visible craniofacial malformations. Treatment is symptomatic and supportive, focusing on the specific manifestations present in each individual. Management often involves a multidisciplinary team including craniofacial surgeons, otolaryngologists, audiologists, and orthodontists. Surgical reconstruction of the mandible and external ear may be performed to improve function and appearance. Hearing aids or bone-anchored hearing devices may be used to address conductive hearing loss. Early audiological assessment is important to support speech and language development. There is currently no cure for the underlying condition.
