Course: Cerebrospinal Fluid in the Middle Ear in a Child

CME Credits: 1.00

Released: 2023-02-23

A 25-month-old child with unilateral hearing loss was referred to a pediatric ear, nose, and throat surgeon in a secondary care hospital. Clinical findings suggested unilateral right middle ear effusion associated with ipsilateral conductive hearing loss. After an initial observation period, a right tympanostomy tube was inserted. During the procedure, a clear liquid pulsating from the middle ear was noted, and samples were sent for ?-2-transferrine analysis. This confirmed the presence of a cerebrospinal fluid (CSF) leak.
