Efficacy of Expansion Pharyngoplasty without Drug-induced Sleep Endoscopy Screening in Obstructive Sleep Apnea.

 Expansion sphincter pharyngoplasty has been shown to be a good alternative to continuous pressure devices in patients with moderate to severe obstructive sleep apnea. On the other hand, drug-induced sleep endoscopy provides information on the pattern of collapse in obstructive sleep apnea, although it is unclear whether this information improves the surgical outcomes.  To evaluate the success rate obtained when performing expansion sphincter pharyngoplasty on a group of patients diagnosed with moderate to severe obstructive sleep apnea who were not previously selected by drug-induced sleep endoscopy.

Cochlear implantation in patients with inner ear bone malformations with posterior labyrinth involvement: an exploratory study.

Inner ear bone malformations are one cause of profound sensorineural hearing loss. This investigation focused on those affecting the posterior labyrinth, especially enlarged vestibular aqueduct syndrome, which is associated with fluctuating and progressive hearing loss. The objectives of this study were to analyze the behavior of the electrical stimulation, auditory functionality and linguistic development in patients with inner ear malformations involving the posterior labyrinth.

Effectiveness of cochlear implant in inner ear bone malformations with anterior labyrinth involvement.

Objective: To study electrical stimulation, auditory functionality, and language development in patients with inner ear malformations involving the anterior labyrinth who underwent cochlear implantation.

Study Design: Retrospective case review.

Setting: Reference hospital for cochlear implantation.
