Cochlear Implant: Sensory Integration Disorder
TMG is the product of his mother's second pregnancy. The pregnancy was complicated by bleeding in the first trimester; however, delivery via C-section was uncomplicated. Apgar scores were 9 and 9. TMG failed his newborn hearing screen at birth in his right ear, five times, utilizing the ALGO 3 newborn hearing screener (Natus Medical, Inc., San Carlos, CA) (passed left ear) and was then referred to follow-up hospital.
The first unsedated auditory brain stem response (ABR) at the children's hospital was performed at age 5 weeks and revealed responses to click stimuli at 25 dB eHL in the right ear, and 15 dB eHL in the left ear with passing TEOAEs in the left ear, and absent in the right ear. TMG was then referred to an ear, nose, and throat (ENT) specialist. A second unsedated ABR took place at age 3.5 months that also revealed responses to click stimuli in the normal range (15 dB eHL) in the left ear, but this time no responses were present in the right ear at the output limits of the equipment to click stimuli, consistent with at least a severe hearing loss. The patient woke up before further testing could be completed.
