Therapie chronisch obstruktiver Funktionsstörungen der Tuba Eustachii

Abstract

This paper reviews the past and present developments in the treatment of chronic obstructive eustachian tube dysfunction. Alongside tube catheterization and bougie insertion, modern approaches such as laser eustachian tuboplasty and balloon eustachian tuboplasty (BET) are described. In BET, transnasal endoscopic insertion via the pharyngeal ostium places a balloon catheter in the cartilaginous portion of the eustachian tube. This is then dilated to a pressure of 10 bar for 2 min. Up until January 2013, 351 chronic obstructive eustachian tube dysfunction patients had been treated in our department using BET. The average preoperative eustachian tube score was 2.1 (± 1.8 standard deviation, SD); 12 months postoperatively it was 6.1 (± 2.6 SD). Of these patients, 87% expressed satisfaction with the improvement in chronic obstructive dysfunction. These results demonstrate that BET is a safe and effective treatment for improving eustachian tube function and ear ventilation.

Advances in the Diagnosis and Magagement of Eustachian Tube Dysfunction

“…There is persistent improvement in seven out of eight patients (in 87.5% of the cases) followed-up for a minimum of 34 months. This safe method is used for effective management of ETD patients [34]. It produces significant improvement in tympanogram values up to 15 months postoperatively [5].…”

Stellenwert der Tubendilatation bei Mittelohradhäsivprozess

“…Eine Schwierigkeit stellt die unscharfe Definition des Begriffs "chronische Tubenfunktionsstörung" sowie die fehlende einheitliche Objektivierbarkeit messtechnischer Verfahren dar. Die Tubendilatation mit dem Bielefelder Ballonkatheter wird einheitlich als sicheres Verfahren eingestuft [6,7,8]. Komplikationsraten werden mit ca.…”

“…Subjektiv berichteten sogar 59 % der Patienten über eine Beschwerdebesserung. In der Literatur wird der Erfolg der Tubendilatation in der Mehrzahl mit > 70 % angegeben [6,7,9]. Die Erfolgsparameter sind jedoch nicht einheitlich und reichen von der subjektiven Einschätzung der Patientenzufriedenheit über die Durchführbarkeit des SVT-Tests, die Auswertung von Tympanogrammen [10] und Messung anhand unterschiedlicher Tubenscores bis hin zur Evaluation anhand von Fragebögen wie des "Eustachian Tube Dysfunction Questionaire" (ETDQ7) [11,12].…”

The rat eustachian tube: Anatomical, histological, and radiological features

“… 4 , 5 When medical approaches fail, surgical procedures, including ventilation tube insertion, laser tuboplasty, and microdebrider tuboplasty, are usually required. 6 , 7 , 8 , 9 However, the efficacy of these surgical approaches remains uncertain owing to inconsistent diagnostic criteria in previous clinical studies and limited clinical experience. Moreover, surgical treatment may cause surgery-related complications such as purulent infection of the middle ear, airway obstruction, airway prolapse, and permanent tympanic membrane perforation.…”
