OBJECTIVE: To evaluate the association between nasal airway function and Eustachian tube (ET) functions and their impact on tympanoplasty in patients with chronic suppurative otitis media (CSOM). MATERIALS AND METHODS: The study group (CSOM group) consisted of 33 patients scheduled to undergo tympanoplasty for CSOM. Two control groups were formed: a nasal septal deviation (NSD) group of 25 patients scheduled to undergo nasal surgery for NSD, and a control group of 25 healthy individuals with no otologic or rhinologic symptoms...

Static pressure changes can alter the configuration and mechanical behavior of the chain of ossicles, which may affect the acoustic transfer function. In mammals, the Eustachian tube plays an important role in restoring ambient middle ear pressure, hence restoring the acoustic transfer function and excluding barotrauma of the middle and inner ear. Ambient pressure fluctuations can be potentially extreme in birds and due to the simple structure of the avian middle ear (one ossicle, one muscle), regulation of the middle ear pressure via reflexive opening of the pharyngotympanic tube appears all the more important...

Patulous Eustachian Tube (PET) is of increasing importance in otology. However, despite the abundance of diseases requiring a differential diagnosis from PET, such as superior semicircular canal dehiscence syndrome, perilymphatic fistula, acute low-tone sensorineural hearing loss, etc., there are currently no established diagnostic criteria for PET. In view of these circumstances, the Japan Otological Society (JOS) Eustachian Tube Committee proposed the diagnostic criteria for Patulous Eustachian Tube in 2012, in order to promote clinical research on PET...

BACKGROUND: Ear symptoms are common among patients presenting to a rhinology clinic. Validated inventories are available for patient quality-of-life in sinonasal disease and Eustachian tube dysfunction (ETD). This study sought to determine the extent of ETD symptoms, using validated metrics, in a large population of patients presenting to a tertiary rhinology clinic. METHODS: Seven-item Eustachian Tube Dysfunction Questionnaires (ETDQ-7) and 22-item Sino-Nasal Outcome Tests (SNOT-22) were prospectively collected from 492 patients treated in a tertiary rhinology clinic...

PURPOSE: Balloon Eustachian tuboplasty (BET) is a new treatment modality addressing chronic obstructive dysfunction of the Eustachian tube (ET). So far, BET has been deemed a safe procedure under general anesthesia with only minor adverse effects. However, individual cases of postoperative emphysema have been reported. In the present retrospective multicenter analysis we determined the incidence rate of this potentially life threatening complication after BET. METHODS: In total we collected data from 3,670 BET procedures performed on 2,272 patients in four tertiary care ENT departments...

Inflammation of the middle ear, known clinically as chronic otitis media, presents in different forms, such as chronic otitis media with effusion (COME; glue ear) and chronic suppurative otitis media (CSOM). These are highly prevalent diseases, especially in childhood, and lead to significant morbidity worldwide. However, much remains unclear about this disease, including its aetiology, initiation and perpetuation, and the relative roles of mucosal and leukocyte biology, pathogens, and Eustachian tube function...

OBJECTIVES: In vivo imaging of the open cartilaginous Eustachian tube (ET) lumen by computed tomography (CT) scan during ET function (ETF) testing to establish new methodology. METHODS: Five adults underwent unilateral ETF testing of an ear with a nonintact tympanic membrane using the forced response test (FRT) to measure the opening pressure (PO), steady state pressure (PS), and flow conductance (CS). Then at baseline and during the PS phase of the FRT, a temporal-bone CT scan with continuous 0...

Tubomanometry (TMM) is a relatively novel method for testing the eustachian tube (ET) function, which is speculated to be closely related to otitis media with effusion (OME). The purpose of this study is to explore the predictive power of TMM value for medication outcomes in adult acute OME. A cohort of 41 adult acute OME patients with 53 affected ears was studied retrospectively. All these patients completed a 2-week treatment including oral Myrtol Standardized Enteric capsules, nasal steroid, and oral antihistamine...

PURPOSE: Determine whether specific risk factors, symptoms and clinical examination findings are associated with hyperbaric oxygen therapy (HBOT) intolerance and subsequent tympanotomy tube placement. MATERIALS AND METHODS: A retrospective case series with chart review was conducted from 2007 to 2016 of patients undergoing HBOT clearance at a tertiary care university hospital in an urban city. Eighty-one (n=81) patient charts were reviewed for risk factors, symptoms and clinical examination findings related to HBOT eustachian tube dysfunction and middle ear barotrauma...

The eyes absent (EYA)-like genes are essential for the formation of sensory organs among fly (Drosophila melanogaster) and mammals. EYA4, one of the vertebrate genes of Eya family, is reported to be causative for late-onset mid-frequency sensorineural hearing loss in humans, while Eya4-deficient mice exhibited congenital profound deafness and otitis media with effusion due to the eustachian tube dysmorphology. Because of the species difference in the phenotype, the pathophysiology of EYA4 in the human cochlea has yet to be elucidated...

Otitis media (OM) refers to inflammatory diseases of the middle ear (ME), regardless of cause or pathological mechanism. Among the molecular biological studies assessing the pathology of OM are investigations of the expression of aquaporins (AQPs) in the ME and Eustachian tube (ET). To date, fifteen studies have evaluated AQPs expression in the ME and ET. Although the expression of individual AQPs varies by species and model, eleven types of AQP, AQP1 to AQP11, were found to be expressed in mammalian ME and ET...

OBJECT: To investigate the long-term effects of balloon Eustachian tuboplasty (BET) from patient's perspective and to discover which symptoms of Eustachian tube dysfunction (ETD) benefit the most from BET. METHOD: We designed a retrospective postal questionnaire based on the seven-item ETD questionnaire (ETDQ-7). Our questionnaire covered the severity of present ETD symptoms in comparison with the preoperative situation, the severity of current overall ear symptoms, and possible surgical interventions after BET...
