There are several options for treatment of mouth anomalies like Tessier cleft number 2-3-7 . These clefts are also seen in various syndromes like Treacher Collins syndrome and hemifacial microsomia, which makes the treatment much more complicated. In this case, treatment of mouth anomalies is a part of the treatment of the syndrome.
Researchers have found that most patients with Treacher Collins syndrome have symmetric external ear canal abnormalities and symmetrically dysmorphic or absent ossicles in the middle ear space. Inner ear structure is largely normal. Most patients show a moderate hearing impairment or greater, and the type of loss is generally a conductive ...

CHARGE syndrome. [1] others. Also any condition that causes significant depression of the nasal bridge or midface retraction can be associated with choanal atresia. Examples include the craniosynostosis syndromes such as Crouzon syndrome, Pfeiffer syndrome, Treacher Collins syndrome, Apert syndrome, and Antley-Bixler syndrome. [1]
More than 120 mutations in the TCOF gene have been identified in people with Treacher Collins syndrome. Most of these mutations insert or delete a small number of DNA building blocks in the TCOF1 gene. TCOF1 mutations lead to the production of an abnormally small, nonfunctional version of treacle or prevent the cell from producing this protein.
