Biomechanics of Eustachian Tube Dysfunction: From Mechanics to Assessment
The Eustachian tube (ET) is a narrow canal connecting the throat with the middle ear. In the UK 0.9 % of the population suffers from obstructive ET dysfunction (ETD), a condition where the ET does not open. Recent breakthroughs in the treatment of ETD highlighted the need for more accurate …

The effectiveness of the laser Eustachian tuboplasty for chronic secretory otitis /
Treatment options for causative Eustachian tube dysfunction are limited and there is no unified approach to a well-defined and established treatment strategy. Absence of adequate methodology is observed, and the effectiveness of many therapies is questionable or limited. The aim of the study- to …

Hearing Function in Obstructive Sleep Apnoea (OSA) patients and its impact with Continuous Positive Airway Pressure (CPAP)
… in OSA could lead to anatomical changes to the eustachian tube, thus impacting middle ear function. In addition, the recurrent decrease in oxygen saturation during sleep with OSA could have potential impacts on cochlear and central auditory function. The treatment for OSA is continuous positive …

Interactions between Streptococcus pneumoniae and Moraxella catarrhalis in polymicrobial communities affect antimicrobial resistance and survival in vivo
… The next step involves ascension through the Eustachian tube to access the middle ear space. For persistance within their host, it has been hypothesized that these bacteria are able to form biofilms on the mucosal epithelial cell surface. Recent studies have shown that these bacteria not only …

Radiological differences between HIV-positive and HIV-negative children with cholesteatoma
… cleft, bony erosion of middle ear structures, Eustachian tube obstruction or soft tissue occlusion of the post-nasal space. Conclusion: HIV-positive paediatric patients with cholesteatoma are more likely to have smaller, sclerotic mastoids compared to HIV-negative patients. They are …

On Pressure Regulation of the Middle Ear
… the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. In this work subjects with chronic central perforation (CCP), healthy ears with ventilation tubes (VTs), attic …

Tubomanometry success rate in clinical practice
Tubomanometriassa potilaan nenänieluun muodostetaan ennalta määritetty ylipaine (30, 40 tai 50 mbar) ja korvatorven avautumista mitataan rekisteröimällä tärykalvon liikkeen aiheuttama paineen muutos korvakäytävästä. Tämän tutkimuksen tarkoituksena oli tutkia tubomanometrian käyttö- ja …

Non-invasive Assessment of Swallowing and Phonation using High-density Electromyography
… involved segmenting the distinctive sound of the Eustachian tube opening. This approach improved temporal accuracy tenfold to approximately 0.025 s. The framework incorporated visualisation of temporal myoelectrical signatures via spatial averaging of regionally defined signals, with morphological …
