Case ReportsStapes fixation accompanied with abnormal facial nerve pathway.
The patient was a 52-year-old woman. She had been aware of her bilateral hearing loss since she was 20 years old. The hearing in her left ear started to deteriorate at the age of 49. ⋯ The malformed superstructure of the stapes was removed carefully. When the ectopic facial nerve was shifted to anteroinferior side, the oval window could be seen. Stapedotomy using a Teflon piston prosthesis was performed with no complications.

Subclavian steal syndrome (SSS) is usually caused by unilateral subclavian artery (SA) occlusion, and bilateral SSS is very rare. Takayasu's arteritis (TA) is a chronic granulomatous form of vasculitis that affects the SA, most commonly in women aged 15-40 years. We report a rare case of bilateral SSS due to TA in a 52-year-old woman, who exhibited severe vertigo. ⋯ The more marked decrease in the blood flow of the vertebrobasilar artery experienced in bilateral SSS compared with unilateral SSS is considered to have caused the severe rotatory vertigo in the present patient. Since the vascular conditions of TA progressively deteriorate, delayed diagnosis and treatment could result in poor outcomes and unfavorable prognosis. We suggest that SSS with TA might require an early detection and treatment as well as careful follow-up for preventing vertigo and other neurological deficits in the vertebrobasilar arterial region.

Long term outcome of tonsillar regrowth after partial tonsillectomy in children with obstructive sleep apnea.
We investigated the long-term effects of partial tonsillectomy, and potential risk factors for tonsillar regrowth in children with obstructive sleep apnea hypopnea syndrome (OSAHS). ⋯ Partial tonsillectomy is sufficient to relieve obstruction while maintaining immunological function. This procedure has several post-operative advantages. Palatine tonsils infrequently regrow. Risk factors include young age, upper respiratory tract infections, history of allergy, and history of acute tonsillitis prior to regrowth.

Gender disparity in subcortical encoding of binaurally presented speech stimuli: an auditory evoked potentials study.
To investigate the influence of gender on subcortical representation of speech acoustic parameters where simultaneously presented to both ears. ⋯ Anatomical, biological and biochemical distinctions between females and males could alter the neural encoding of the acoustic cues of speech stimuli at subcortical level. Females have an advantage in binaural processing of the slow and fast elements of speech. This could be a physiological evidence for better identification of speaker and emotional tone of voice, as well as better perceiving the phonetic information of speech in women.

Case ReportsSurgical management for isolated cricoid fracture causing arytenoid immobility.
Cricoid cartilage fractures usually occur concurrently with disorders of laryngeal function. In, particular, displaced cricoid lamina fractures can affect arytenoid movement. ⋯ Here we present a case in which an isolated cricoid cartilage fracture with arytenoid, immobility due to displacement of the fracture in the cricoarytenoid joint space was successfully, treated. Our findings suggest that a combination of external approaches with temporary, cricothyrotomy and wide suturing of the entire cricoid framework has the potential to improve, arytenoid movement and prevent associated complications.
