Utility of otoacoustic emissions and olivocochlear reflex in predicting vulnerability to noise-induced inner ear damage.

Aim: The aim of the present study was to explore the possible utility of otoacoustic emissions (OAEs) and efferent system strength to determine vulnerability to noise exposure in a clinical setting.

Materials And Methods: The study group comprised 344 volunteers who had just begun mandatory basic training as Hellenic Corps Officers Military Academy cadets. Pure-tone audiograms were obtained on both ears.

Systemic, intratympanic and combined administration of steroids for sudden hearing loss. A prospective randomized multicenter trial.

Purpose: The purpose of this prospective, randomized, multicenter clinical trial was to compare the therapeutic efficacy of systemic versus intratympanic versus combined administration of steroids in the treatment of idiopathic sudden sensorineural hearing loss.

Methods: 102 patients with an up to 14 days history of idiopathic sudden sensorineural hearing loss were randomized to 1 of 3 arms and followed prospectively. Group A (35 patients) received prednisolone intravenously followed by methylprednisolone orally, whereas Group B (34 patients) were administered intratympanic methylprednisolone.

Bardet-Biedl syndrome and a large concha bullosa pyocele.

Bardet-Biedl syndrome is a rare disease involving rode cone dystrophy, polydactyly, obesity, learning disabilities, hypogonadism and renal anomalies, symptoms caused by immotile cilia dysfunction. We report the first case of this syndrome in a teenager with an endonasal mass secondary to pyocele of a concha bullosa. The patient was treated successfully with endoscopic sinus surgery.

Vestibular evoked myogenic potentials in children after cochlear implantation.

Objective: The aim of this study was to report the effect of unilateral cochlear implantation to vestibular system using vestibular evoked myogenic potentials (VEMPs) by air-conduction in a sample of children aged less than 5 years.

Materials: This study consisted of 10 children (6 boys and 4 girls), who underwent cochlear implantation surgery at our clinic, and 8 normal hearing children (5 boys and 3 girls) matched for age. The VEMPs were performed before, 10 days, and 6 months after surgery.

Vertigo during the Epley maneuver and success rate in patients with BPPV.

To investigate whether reported vertigo during the Epley maneuver predicts therapeutic success in patients with benign paroxysmal positioning vertigo of the posterior semicircular canal (pc-BPPV). Fifty consecutive adult patients with pc-BPPV, based on a positive Dix-Hallpike test (DHT), were treated with the Epley maneuver and retested after 2 days. Patients were asked to report the presence of vertigo upon assuming each of the four positions of the maneuver.

Conversion of canalolithiasis to cupulolithiasis in the course of a horizontal benign paroxysmal positional vertigo case.

The benign paroxysmal positional vertigo of the horizontal semicircular canal is manifested with either geotropic or apogeotropic horizontal nystagmus. A 61-year-old male patient who experienced repeated episodes of positional vertigo is presented in this study. The vertigo was reported to be more severe while rotating his head to the left and then to the right.
