Aurélie Vandevoorde, Marc T Williams, Elsa Ukkola-Pons, Mary Daval, Denis Ayache
BACKGROUND: Sensorineural complications of stapes surgery are rare but potentially serious. Imaging is usually performed to identify an underlying cause, such as excessive intravestibular penetration of the prosthesis or pneumolabyrinth suggesting perilymphatic fistula. Unfortunately, there is very little data in an unselected series of uneventful patients.The aim of this study was to analyze the depth of prosthesis penetration within the vestibule and the rate of pneumolabyrinth the day or the day after the procedure by performing a cone beam computed tomography of the temporal bone in a cohort of unselected patients, and to correlate imaging findings to clinical outcome...

CONCLUSIONS: Osteoclasts are unlikely to be involved in bone resorption in middle ear cholesteatoma. OBJECTIVE: The authors searched for osteoclasts in undecalcified bone sections in patients with middle ear cholesteatoma to determine whether and to what extent these cells are involved in this disease. METHODS: Twelve patients, eight men and four women, aged 30-87 years, who underwent tympanomastoidectomy were enrolled. Six patients had primary acquired middle ear cholesteatoma (cholesteatoma group) and the other six patients had other otologic diseases including otosclerosis, non-cholesteatomatous chronic otitis media, adhesive otitis media, perilymphatic fistula and ossicular malformation (control group)...

INTRODUCTION: Onset of cochleovestibular symptoms (hearing loss, dizziness or instability, tinnitus) after a dive (scuba or breath-hold diving) warrants emergency transfer to an otology department. One priority is to investigate the possibility of the development of decompression sickness with a view to hyperbaric oxygen treatment of bubble-induced inner-ear damage. If this injury is ruled out, inner-ear barotrauma should be considered together with its underlying specific injury pattern, perilymphatic fistula...

Pneumolabyrinth is a rare condition with air bubbles existing in the vestibule and/or cochlea. We report a case of pneumolabyrinth without trauma that was suspected to be caused by labyrinthitis. A 65-year-old man presented with vertigo and hearing loss in the left ear after catching a cold. Computed tomography performed after there had been no improvement in the patient's symptoms showed the presence of air bubbles in the vestibule, semicircular canals and cochlea. The patient was transferred to our hospital with suspected perilymphatic fistula...

UNLABELLED: Hearing loss is a common functional disorder after trauma, and radiologists should be aware of the ossicular, labyrinthine or brain lesions that may be responsible. After a trauma, use of a systematic approach to explore the main functional components of auditory pathways is essential. Conductive hearing loss is caused by the disruption of the conductive chain, which may be due to ossicular luxation or fracture. This pictorial review firstly describes the normal 2-D and 3-D anatomy of the ossicular chain, including the incudo-malleolar and incudo-stapedial joints...

HYPOTHESIS: Round window reinforcement leads to conductive hearing loss. BACKGROUND: The round window is stiffened surgically as therapy for various conditions, including perilymphatic fistula and superior semicircular canal dehiscence. Round window reinforcement reduces symptoms in these patients. However, it also reduces fluid displacement in the cochlea and might therefore increase conductive hearing loss. METHODS: Perichondrium was applied to the round window membrane in nine fresh-frozen, nonpathologic temporal bones...

Among 95 patients with sudden sensorineural hearing loss who received inpatient treatment at our hospital within the 27-month period between October 2009 and December 2011, those in whom hearing loss was aggravated after diagnosis were compared with a control group. Hearing loss aggravation was defined as a decrease by 10 dB or more in the mean hearing threshold at 5 frequencies from 250 to 4,000 Hz or decrease of 15 dB or more in the hearing threshold at 2 consecutive frequencies. Hearing loss was aggravated after diagnosis in 22 (23...

Traumatic pneumolabyrinth is a relatively rare entity. We report the case of a unilaterally deaf woman with pneumolabyrinth who had suffered penetrating injury 15 years ago. This past history indicated that the case was late pneumolabyrinth occurring from undiagnosed old posttraumatic perilymphatic fistula. In Japan, most cases of traumatic pneumolabyrinth are caused by penetrating injury with an ear pick. Dizziness often improves within several months. Immediate surgical intervention is recommended for hearing loss, but the hearing outcome is not satisfactory...

Diagnosis of Menière's disease is made with a characteristic patient history, including discrete episodes of vertigo lasting 20 min or longer, accompanied by sensorineural hearing loss, which is typically low frequency at first, aural fullness, and tinnitus. Workup includes audiometry, a contrast enhanced MRI of the internal auditory canals, and exclusion of other diseases that can produce similar symptoms, like otosyphilis, autoimmune inner ear disease, perilymphatic fistula, superior semicircular canal syndrome, Lyme disease, multiple sclerosis, vestibular paroxysmia, and temporal bone tumors...

OBJECTIVES: Rupture of the round window membrane with consecutive development of a perilymphatic fistula (PLF) is still a matter of controversial debate in the pathogenesis of idiopathic sudden sensorineural hearing loss (SSHL). Until now no consensus exists about whether these patients benefit from performing an exploratory tympanotomy with sealing of the round window. The aim of the present study was to analyze critically the effectiveness of sealing the round window membrane in patients with SSHL...

Perilymphatic fistula (PLF) is an abnormal condition in which a communication is present between the perilymphatic space of the inner ear and the middle ear or mastoid, secondary to a dehiscence in the otic capsule, oval or round window. LF may induce hearing loss, tinnitus, aural fullness, vertigo, disequilibrium, or a combination of these symptoms; the vagueness of symptoms caused by PLF and the lack of specificity of clinical signs and symptoms make the diagnosis elusive. We report a video of a positive PLF test induced by the application of pressure on the tragus, just anterior to the left external auditory canal in a patient with cholesteatoma and PLF of lateral semicircular canal confirmed by CT scan imaging...
