Benign paroxysmal positional vertigo (BPPV) is the most frequent type of vertigo. The treatment of canalithiasis of the posterior semicircular canal consists in performing a particle-repositioning maneuver, such as the Epley maneuver (EM). However, the EM is not effective in all cases. The objective of this study is to identify risk factors, which predict the EM failure, among the clinical variables recorded in anamnesis and patient examination. This is an observational prospective multicentric study. All patients presenting with BPPV were recruited and applied the EM and appointed for a follow-up visit 7 days later...

The anatomical differences between the newborn ear and the adult one result in different input admittance responses in newborns than those in adults. Taking into account fluid-structure interactions, we have developed a finite-element model to investigate the wideband admittance responses of the ear canal and middle ear in newborns for frequencies up to 10 kHz. We have also performed admittance measurements on a group of 23 infants with ages between 14 and 28 days, for frequencies from 250 to 8000 Hz with 1/12-octave resolution...

According to Coombs and Gell, cell-mediated immune responses belong to type IV reactions and are borne mainly by T lymphocytes. The eliciting allergens are usually so-called haptens. Haptens are substances which develop to whole antigens only by binding to protein carriers. In otorhinolaryngology, delayed allergic hypersensitivities are apparent mainly as contact eczemata. Facial dermatitis, auricle and ear canal eczema as well as perioral eczema belong to the most common forms of contact dermatitis in ENT patients...

OBJECTIVE: Otowicks are used to treat otitis externa with significant ear canal oedema. This study investigates how well drops penetrate through to reach the deep canal and whether it is safe to leave otowicks in the canal for more than 2 days. METHODS: Sterile otowicks were inserted into mock ear canals and vertically over pseudomonas-seeded agar plates whilst gentamicin or ciprofloxacin drops were administered. The time taken for drops to penetrate through the otowick was recorded...

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...

Although several researchers have tried various canalith repositioning procedures for lateral canalolithiasis, a standard treatment has not been established. We adopt 120° rotation, which is anatomically appropriate because the principle of cure may be the fixing of pathological debris to the dark cells of the utricle. The aims of this study were to clarify the efficacy rate of the affected-ear-up 120° maneuver and to elucidate the appearance rate of lying-down nystagmus in patients with lateral canalolithiasis...

Little is known about middle and inner ear development during the second and third parts of human fetal life. Using ultra-high resolution Microcomputed Tomography coupled with bone histology, we performed the first quantitative middle and inner ear ossification/mineralization evaluation of fetuses between 17 and 39 weeks of gestational age. We show distinct ossification paces between ossicles, with a belated development of the stapes. A complete cochlear bony covering is observed within the time-frame of the onset of hearing, whereas distinct time courses of ossification for semicircular canal envelopes are observed in relation to the start of vestibular functions...

REVIEW
Jeremy Hornibrook
The technique of transtympanic electrocochleography was initially developed as an objective hearing threshold test by Eggermont. Gibson et al. (1977) claimed that an enlarged direct current component of the action potential (AP) called the summating potential (SP) is an indication of endolymphatic hydrops, later confirmed by Coates who proposed an SP/AP ratio measure. This led to numerous publications using diagnostic ratios of 0.33-0.35. The insensitivity led to an eventual disenchantment with the test as a reliable objective test for Meniere's disease...
