A Possible Incomplete Form of Treacher Collins Syndrome: A Case Report.

Treacher Collins syndrome (TCS) is a rare genetic disorder that affects craniofacial development due to malformation of the first and second branchial arches. The TCOF1 gene is mainly responsible for this condition. Here, we present a case of a 13-year-old adolescent girl with complaints of maligned teeth with conductive deafness. On clinical examination, she had retrognathia, a broad nose, maligned teeth, a high arch palate, and midfacial hypoplasia. On the basis of the clinical findings, a diagnosis of a mild-variant TCS was made as eyes were not involved and supportive treatment was given to the patient. The symptoms of the disease have a varying range of severity. Early diagnosis and supportive treatments, which include multidisciplinary treatment involving pediatrics, otolaryngologists, audiologists, orthodontists, and psychologists, are very important for the management of such cases.
