Assessing the usefulness of tubomanometry as a diagnostic tool in Eustachian tube dysfunction.

Purpose: This study aims to evaluate the validity and reliability of tubomanometry (TMM) in diagnosing obstructive Eustachian tube dysfunction (OETD) before balloon Eustachian tuboplasty (BET).

Methods: A prospective cohort study was conducted, involving 25 patients with sinonasal pathology, 75 patients with middle ear disease, and 25 healthy subjects, totaling 250 ears. All participants underwent comprehensive physical examinations, including TMM, nasal videoendoscopy, otoendoscopy, Valsalva maneuver (VM), tympanometry, and audiometry.

DISE with CPAP: a useful procedure to evaluate upper airway collapsibility.

Purpose: Drug-induced sleep endoscopy (DISE) is commonly performed in patients suffering obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) intolerance. We aimed to evaluate the effects of adding CPAP to DISE to provide understanding of the reason of its failure and better guidance in future therapeutic decisions.

Methods: A retrospective observational descriptive study was conducted on CPAP-intolerant patients with moderate-severe OSA.
