The aim of this study was to assess the main ear malformations, hearing loss and auditory rehabilitation in children with Treacher Collins syndrome.


We performed a retrospective study of 9 children with Treacher Collins syndrome treated in a central hospital between January 2003 and January 2013.


This study showed a high incidence of malformations of the outer and middle ear, such as microtia, atresia or stenosis of the external auditory canal, hypoplastic middle ear cavity, dysmorphic or missing ossicular chain. Most patients had bilateral hearing loss of moderate or high degree. In the individuals studied, there was functional improvement in patients with bone-anchored hearing aids in relation to conventional hearing aids by bone conduction.


Treacher Collins syndrome is characterized by bilateral malformations of the outer and middle ear. Hearing rehabilitation in these children is of utmost importance, and bone-anchored hearing aids is the method of choice.

Evaluar las principales malformaciones del oído, hipoacusia y la rehabilitación auditiva en los niños con síndrome de Treacher-Collins.


Estudio retrospectivo de 9 niños con síndrome de Treacher-Collins tratados en un hospital central, entre enero de 2003 y enero de 2013.


Este estudio demostró una alta incidencia de malformaciones del oído externo y medio, como microtia, atresia o estenosis del conducto auditivo externo, la cavidad timpánica hipoplásica, la cadena de huesecillos dismórfica, o ausente. La mayoría de los pacientes tenían una hipoacusia de conducción grado moderado o alto. En los sujetos estudiados, se observó una mejoría funcional en los pacientes con audífono anclado en hueso en relación con los audífonos convencionales de conducción ósea.


El síndrome de Treacher-Collins se caracteriza por malformaciones bilaterales del oído externo y medio. La rehabilitación auditiva en estos niños es muy importante, y el audífono anclado en hueso es el método de elección.
