Q

How does cleft palate cause conductive hearing loss?

A

the malformation of the cleft palate prevents the drainage of secretions and the allowance of air into the middle ear, thereby leading to a buildup of fluid which causes otitis media and conductive hearing loss

Q

How does cleft palate impact the eustachian tube?

A

Since the tensor veli palatini muscle, a muscle of the velum, contracts the eustachian tube, it does not contract due to the malformation of the soft palate, thereby affecting the eustachian tube

Q

When assessing children with clefts, what does an SLP assess?

A

velopharyngeal port via oral mech and instrumentals (e.g., nasoendoscopy); assess speech via speech sample and the administration of the Iowa Articulation test; assess language, phonation, and resonance

Q

When treating children with clefts, an SLP should do the following:

A

surgery is needed first to repair the palate; for speech sound disorders, teach the child compensatory strategies and use electropalatography (electrodes on an artificial palate), for resonance disorders use voice therapy after the child has had their velopharyngeal port repaired
