Perilymphatic fistulas of the inner ear constitute abnormal leaks of perilymphatic fluid into the middle ear or mastoid air cell system and represent a rare cause of otorrhea. We report the case of a 5-month-old child presenting with sudden otorrhea. High resolution CT cisternography showed a malformation of the middle ear and a passage of contrast-enhanced CSF into the tympanic cavity through the left oval window. Surgery confirmed a tear of the tympanic membrane as well as a stapes malformation with aplasia of the crura and an associated perilymphatic fistula through a defect in the stapes footplate. The fistula was closed with adipose tissue from the ear lobe.

We present a case of a perilymphatic fistula (PLF) caused by Eustachian tube air inflation (ETAI) that was diagnosed using cochlin-tomoprotein (CTP) testing and successfully treated using transcanal endoscopic ear surgery to seal the inner ear window. A 77-year-old woman developed hearing loss and dizziness after undergoing ETAI at a local ear, nose, and throat clinic. Despite initial bed rest and steroid pulse therapy, the hearing did not improve, and transcanal endoscopic ear surgery was performed to repair the PLF.

Introduction: Based on clinical practice guidelines, the application of corticosteroids as a first-line therapy is common. Although sudden sensorineural hearing loss (SSHL) etiology is primarily idiopathic, hearing loss can result from a perilymphatic fistula (PLF). Recent findings show evidence of a specific rate of PLF based on a cochlin-tomoprotein (CTP) detection test.

Pneumolabyrinth is a rare entity in a case of squamous chronic otitis media in the practice of otology. We report a case of 56 year male, a known case of Squamous Chronic Otitis Media who was diagnosed as a case of Pneumolabyrinth associated with a Perilymphatic fistula. Diagnosis was done with the help of audiometry and High-Resolution Computed Tomography of Temporal Bone in background of his symptoms.

Conductive hearing loss caused by external or middle ear problems prevents the transmission of sound waves from the external auditory canal to the cochlea, and it is a common condition, especially in pediatric patients aged 1-5 years. The most common etiological factors are otitis media and cerumen during childhood. In some patients, external and middle ear functions and structures may be normal bilaterally despite the air-bone gap on the audiogram.
