“…Cochlear conductive hearing loss also has been reported in Meniere's disease, although another hypothesis is proposed but the Vestibular organs dysfunction because of stiffness caused by hydrops might be the reason for the conductive component hearing loss in this disease [111]. Albeit Conductive or Mixed Hearing loss is more common in Superior, posterior, lateral Semicircular Canals Dehiscence and Large Vestibular Aqueduct Syndrome but Sensorineural hearing loss has been reported as well so type of the hearing loss depends on the site and degree of the lesion as Vestibular system contains pigmented and transitional cells [112][113][114][115]. Pupil Dilation following auditory stimuli has been observed [116].…”

“…Head trauma or dural vascular pulsations, particularly in the setting of increased intracranial pressure, can gradually erode bone and result in a dehiscence (7). Iatrogenic causes of an inner ear third window have also been described, such as inadvertently exposing the posterior semicircular canal during an endolymphatic shunt procedure (8)(9)(10)(11). A perilymph fistula may occur after stapedectomy, cochlear implantation, or due to a failed posterior canal occlusion for BPPV (12)(13)(14).…”

Objective: To present a case of an iatrogenic inner ear third window after vestibular schwannoma microsurgery. Patients: A 42-year-old male presented 9-months after leftsided retrosigmoid approach for an intracanalicular vestibular schwannoma with hearing-preservation attempt performed elsewhere. Immediately postoperatively, he developed the following disabling and persistent symptoms on the ipsilateral side: autophony, pulsatile tinnitus, high-pitched ringing tinnitus, and hearing his footsteps. He denied vertigo. Otoscopy was normal. Tuning fork ( 512-Hz) lateralized to the left and Rinne was negative on the left. Audiogram demonstrated a severe mixed hearing loss and 10% aided word-recognition score. High-resolution CT demonstrated violation of the common crus and dehiscence of bone along the medial vestibule suggestive of an iatrogenic inner ear third window. Interventions: Labyrinthectomy and concurrent cochlear implantation. Main outcome measures: Resolution of third window symptoms, open-set speech recognition, tinnitus suppression.Results: Patient reported immediate resolution of third window symptoms after labyrinthectomy and cochlear implantation. He demonstrates open-set word recognition of 64% at 1-year postoperatively and tinnitus suppression with his cochlear implant on. Conclusions: Iatrogenic third window symptoms can occur after hearing-preservation vestibular schwannoma microsurgery. Patients with sufficient hearing preservation who are disabled by third window symptoms yet lack sound clarity and useful hearing may be considered for labyrinthectomy and concurrent cochlear implantation. This intervention effectively extinguishes third window symptoms by destroying residual auditory function and simultaneously provides an opportunity to restore useful hearing and suppress tinnitus, thereby enhancing overall quality of life.
