Apnea and oxygen desaturations in children treated with opioids after adenotonsillectomy for obstructive sleep apnea syndrome: a prospective pilot study.

Background: Recent case reports have alerted the medical community of fatality in children receiving codeine after tonsillectomy and/or adenoidectomy for obstructive sleep apnea syndrome.

Objective: The objective of this study was to compare the rates of oxygen desaturation before and after adenotonsillectomy in children with obstructive sleep apnea syndrome (OSAS), and to examine the relationship between cytochrome P450 2D6 (CYP2D6) genotype and respiratory events.

Study Design: This was a prospective observational study.

Staple-assisted endoscopic management of Zenker's diverticula: a role in the geriatric population.

Endoscopic stapling technique (modified Dohlman procedure) for treatment of hypopharyngeal diverticula (Zenker) has been shown to produce outcomes similar to open techniques but with shorter operating times and shorter hospitalization.

Tactile dysgeusia: a new clinical observation of middle ear and skull base surgery.

Objective: To describe a new clinical observation of "tactile dysgeusia," a phenomenon associated with otologic and skull base surgery likely caused by injury to the chorda tympani nerve (CTN) or the nervus intermedius (NI) with subsequent aberrant cross-innervation with somatosensory fibers in the surgical field.

Study Design: Descriptive case series.

Setting: Tertiary university referral center.
