Symptoms: Hearing Loss
Hearing loss is a common symptom experienced by individuals with Stickler syndrome, although the degree of hearing loss can vary from person to person and may even worsen over time. There are two main types of hearing loss associated with this condition.
The first type, known as conductive hearing loss, occurs due to abnormalities in the middle ear. This means that sound waves are unable to travel properly across the ear, resulting in a reduced ability to hear. The second type, called sensorineural hearing loss, affects the inner ear and the nerves responsible for transmitting sensory information to the brain. This can further impede one’s ability to hear and process sounds.
In addition to these types of hearing loss, children with Stickler syndrome who also have a cleft palate may experience a condition called glue ear. This occurs when a thick, sticky fluid builds up behind the eardrum, causing further impairment in hearing. Furthermore, individuals with Stickler syndrome are at an increased risk of developing ear infections, which can further exacerbate hearing difficulties.
Symptoms: Joint Abnormalities in Stickler Syndrome
Individuals with Stickler syndrome often experience skeletal abnormalities and joint problems. One common symptom is hypermobility, where the joints are loose and overly flexible, particularly in children and young adults. Arthritis is another prevalent symptom, which can appear before the age of 40. Additionally, the weakness in the bones associated with Stickler syndrome can lead to osteoporosis and an increased risk of fractures. Abnormal curvatures of the spine, including scoliosis and kyphosis, as well as flat vertebrae (platyspondyly), may also develop. Chronic back pain is another potential symptom experienced by some individuals with Stickler syndrome.
