Abstract
BACKGROUND To prospectively evaluate the technical efficacy and safety of the double-lumen eustachian tube (ET) balloon catheter in patients with ET dysfunction. METHODS Patients who were diagnosed with ET dysfunction and needed balloon eustachian tuboplasty (BET) were prospectively enrolled. A double-lumen ET balloon catheter was used to dilate the ET and inject medicine. Efficacy results were assessed by the injection channel patency (ICP) rate, the injection reached the expected site (IRES) rate, and the improvement in eustachian tube function was evaluated by the seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score. Safety results were assessed in terms of adverse events and device defects. RESULTS BET was successfully attempted in 87 patients from April 2022 to August 2022 at two academic medical centers in China (01, 02). The ICP rate was 100%, and the IRES rate was 88.51%. The overall ETDQ-7 score was significantly reduced ( p < 0.001) postsurgically at both centers. There were no major complications or device defects. CONCLUSION The double-lumen ET balloon catheter is technically effective and safe for the treatment of ET dysfunction.

Abstract
OBJECTIVE Determine if the middle ear (ME) trans-mucosal nitrous oxide (N2O) gas exchange rate can be pharmacologically modulated by the nasal application of a vasoconstrictor. METHODS In a randomized, double-blind, crossover study, 20 adults received a nasal spray challenge containing either oxymetazoline or saline (placebo). At each session, subjects were fitted with a non-rebreathing mask and breathed room air for 20 minutes, 50% N2O:50% O2 for 20 minutes, and 100% O2 for 10 minutes. Throughout, heart rate, blood pressure (BP), and blood O2 saturation were monitored, and bilateral ME pressure was recorded by tympanometry every minute. The primary outcome measure was the slope of the ME pressure-time function for the experimental period, a direct measure of the transMEM N2O exchange constant. The effects of treatment, session, and period on the measured vital signs and of treatment, session, disease history, and ear on the ME pressure-time slopes were evaluated for statistical significance using repeated measures ANOVAs. RESULTS The analysis documented a significant effect of period on O2 saturation (N2O > room air, P = .03) and of treatment on blood pressure (oxymetazoline > placebo, P < .02) and the ME pressure-time slope (placebo > oxymetazoline, P = .05). CONCLUSION The exchange rate across the ME mucosa of inert gases can be decreased by topical treatment of the nasal mucosa with oxymetazoline.

Abstract
INTRODUCTION Acute otitis media (AOM) is the most common childhood bacterial infection and also the leading cause of conductive hearing loss in children. Currently, there is an urgent need for developing novel therapeutic agents for treating AOM. AREAS COVERED Structured search of current literature. PubMed was searched for published literature in areas of pharmacotherapeutics, preventive therapies and complementary treatments for OM. The intent of this review is to provide a comprehensive evaluation of therapeutics for AOM, including preventive modalities and complementary medicine. EXPERT OPINION the management of AOM in young children is still evolving and depends on patterns of bacterial colonization and antimicrobial resistance in the community. The introduction of vaccinations against potential respiratory tract pathogens has altered the frequency of recovery of pathogens causing ear infections in children. Even though not all patients require antimicrobial therapy to overcome their infection, these agents improve symptoms faster and lead to fewer treatment failures. Further studies are warranted to evaluate which patients would best benefit from antimicrobial therapy.
