INTRODUCTION: Injuries to the peripheral auditory system are among the most common results of high intensity impulsive acoustic exposure. Prior studies of high intensity sound transmission by the ossicular chain have relied upon measurements in animal models, measurements at more moderate sound levels (i.e. < 130 dB SPL), and/or measured responses to steady-state noise. Here, we directly measure intracochlear pressure in human cadaveric temporal bones, with fiber optic pressure sensors placed in scala vestibuli (SV) and tympani (ST), during exposure to shock waves with peak positive pressures between ∼7 and 83 kPa...

OBJECTIVE: The bactericidal/permeability-increasing, fold-containing family member A1 (BPIFA1) gene codes a secretory protein (BPIFA1), which is present in the respiratory tract mucosa, and is part of the innate immune system. This study aimed to prove that BPIFA1 gene expression exists in the human middle ear mucosa. MATERIALS AND METHODS: In total, 32 patients participated in the study between March 2016 and September 2016. Seventeen patients had chronic otitis media with cholesteatoma (COMC) and 15 had bilateral sensorineural hearing loss (BSHL)...

OBJECTIVES: To describe a multicenter study regarding surgical management of bilateral congenital cholesteatoma (BCC) and underline the importance of endoscopes in the management of this condition. In BCC, hearing preservation is more crucial than in unilateral cases. The endoscopic approach allows complete removal of cholesteatoma via a minimally invasive technique offering low residual disease rates while preserving the normal physiology of the middle ear and possibly the ossicular chain...

HYPOTHESIS: Acoustic stimulation generates measurable sound pressure levels in the semicircular canals. BACKGROUND: High-intensity acoustic stimuli can cause hearing loss and balance disruptions. To examine the propagation of acoustic stimuli to the vestibular end-organs, we simultaneously measured fluid pressure in the cochlea and semicircular canals during both air- and bone-conducted sound presentation. METHODS: Five full-cephalic human cadaveric heads were prepared bilaterally with a mastoidectomy and extended facial recess...

Lateral and sigmoid sinus malformations are uncommon and dangerous anatomical variations that surgeons may encounter when performing a retroauricular approach. We report three cases of rare temporal bone venous sinus anomalies seen in patients who underwent cochlear implant surgery. The first patient had a diagnosis of CHARGE syndrome and presented a bilateral persistent petrosquamosal sinus with sigmoid sinus agenesis, which made mastoidectomy for cochlear implantation difficult. The second patient presented an anomalous venous lake in the occipital region, which communicated the left dural venous sinuses with a conglomerate of pericranial vessels in the left nuchal region, also consistent with left sinus pericranii...
