Benign Paroxysmal Positional Vertigo Secondary to Mild Head Trauma.

Objectives: We studied the clinical characteristics, nystagmographic findings, and treatment outcome of a group of patients with benign paroxysmal positional vertigo (BPPV) secondary to mild head trauma and compared them with a group of patients with idiopathic BPPV.

Methods: The medical records of 33 patients with BPPV associated with mild head trauma were reviewed. Data of a complete otolaryngological, audiological, neurotologic, and imaging evaluation were available for all patients.

Subcutaneous emphysema and pneumomediastinum after tonsillectomy.

Cervicofacial subcutaneous emphysema is a rare complication of tonsillectomy that often resolves spontaneously but may progress to obstruct upper airways or spread to the thorax causing pneumomediastinum or pneumothorax. The mechanisms by which subcutaneous emphysema and pneumomediastinum may develop after tonsillectomy are poorly understood. A case of a 21-year-old female undergoing routine adenotonsillectomy, who developed cervicofacial emphysema and pneumomediastinum, is presented.

A longitudinal study of changes in distortion-product otoacoustic emissions and pure-tone thresholds in an industrial setting.

In a longitudinal study of 76 noise-exposed industrial workers, 34 (68 ears) of them were available for final evaluation after 9 years of observation. Distortion-product otoacoustic emissions (DP) at 65/55 dB SPL and pure-tone audiometry were used to detect noise-induced inner ear changes. Repeated measures analyses of variance were made on the subjects and in a control group, whereas significant threshold shifts (STS) and significant emission shifts (SES) were calculated.

Benign paroxysmal positional vertigo secondary to vestibular neuritis.

The aim of this study was to present the demographic, pathogenetic and clinical features of benign paroxysmal positional vertigo (BPPV) secondary to vestibular neuritis (VN). The medical records of 22 patients, who presented with BPPV within 12 weeks after the onset of VN, were reviewed. Data of a complete otolaryngological, audiological, neurotologic and imaging evaluation were available for all patients.
