Treacher Collins Syndrome (TCS) is a rare genetic condition that affects the development of the bones and tissues of the face. Its features can vary widely from person to person. Because the condition may affect the structures of the ears, individuals with Treacher Collins Syndrome may also experience hearing difficulties.
Understanding the condition, its symptoms, and available support can help families make informed decisions about healthcare and hearing management.

What Is Treacher Collins Syndrome?
Treacher Collins Syndrome is a genetic disorder that primarily affects craniofacial development. It may influence the formation of the cheekbones, jaw, eyes, and ears. The condition is present from birth, although the severity can vary significantly.
Many individuals with TCS have normal intelligence, but hearing loss may occur due to differences in the development of the outer or middle ear.
What Causes Treacher Collins Syndrome?
Treacher Collins Syndrome is commonly associated with changes in certain genes involved in facial development. In many cases, it is linked to variants in the TCOF1 ...
... gene, although other genes may also be involved.
The condition can be inherited from a parent or occur as a new genetic change. Genetic counselling may help families understand inheritance patterns and available testing options.
Common Symptoms of Treacher Collins Syndrome
Physical features and symptoms may differ between individuals. Common characteristics can include:
Underdeveloped cheekbones
Differences in the shape or size of the jaw
Downward-slanting eyes
Cleft palate in some cases
Differences in the external ear
Narrow or absent ear canals
Hearing loss
Hearing loss associated with TCS is often conductive, meaning sound may have difficulty travelling efficiently through the outer or middle ear.
Treacher Collins Syndrome and Hearing Loss
Ear-related differences can affect how sound reaches the inner ear. Some individuals may have underdeveloped ear canals or middle-ear structures, which can contribute to hearing difficulties.
Early hearing assessment is especially important for children with Treacher Collins Syndrome. Regular monitoring can help identify hearing changes and support communication and language development.
Depending on the type and degree of hearing loss, an audiologist may recommend suitable hearing solutions, including hearing aids or other assistive devices.
Diagnosis and Management
Treacher Collins Syndrome may be identified through a clinical examination, hearing evaluations, imaging tests, and, when appropriate, genetic testing. Management usually involves a multidisciplinary team that may include genetic specialists, audiologists, ENT professionals, speech therapists, and other healthcare providers.
Because hearing needs can change over time, regular hearing evaluations are important.
