Background: Most of the tests to evaluate the eustachian tube (ET) function are focused on the ventilation function of the ET.

Aim: Here we evaluate mucociliary function of the ET in patients with ET dysfunction.

Materials And Methods: Ten patients with ET dysfunction were enrolled into the study. Six patients had chronic tympanic membrane retraction and four patients had chronic middle ear effusion (MEE). All patients had intact tympanic membranes. Tympanometry and clinical examinations were done to all patients. Mucociliary function was evaluated with technetium labeled albumin and blue dye. Tympanometry and clinical examinations were done to six patients with chronic tympanic membrane retraction and four patients with chronic middle ear effusion (MEE). Mucociliary function of the ET was evaluated with technetium labeled albumin and blue dye placed into middle ear through an intact tympanic membrane and followed from nasopharynx ET orifice (blue dye) and with gamma camera (technetium).

Results: Blue dye was observed in tubal orifice in six (6 of 10) patients during 30 min observation. Five of those patients (5 of 6) had tympanic membrane retraction and one patient (1 of 6) had MEE. Tracer activity decreased from middle ear in six (6 of 10) patients. Four of those patients had tympanic membrane retraction and two had MEE.

Conclusion: Mucociliary function of the ET seems to be better in patients with tympanic membrane retraction than patients with middle ear effusion.

Significance: Mucociliary function of the ET is an important function for middle ear aeration, blue dye test is easily available to be used also in clinical practice.

Balloon Eustachian tuboplasty under local anesthesia: Is it feasible?

Laryngoscope 2017 May 3;127(5):1021-1025. Epub 2017 Feb 3.

Department of Otorhinolaryngology-Head and Neck Surgery, Head and Neck Center, Helsinki University Hospital and University of Helsinki, Helsinki, Finland.

Objective: To study whether balloon Eustachian tuboplasty (BET) is a feasible and safe procedure under local anesthesia.

Study Design: Prospective multicenter case-control study.

Methods: Patients undergoing either BET (n = 13) or endoscopic sinus surgery (ESS) (n = 12) under local anesthesia, with the possibility of sedation and analgesia, were monitored during the procedure and recovery period for possible adverse effects. After the procedure, the patients responded to a questionnaire assessing their experience.

Results: No adverse effects were detected in the BET group. Patients in the BET group reported similar Visual Analog Scale scores for pain during the operation as the ESS group (5.0 ± 0.7 vs. 3.2 ± 0.7, mean ± standard error of the mean). However, patients in the BET group experienced more discomfort (4.2 ± 0.6 vs. 2.5 ± 0.3, respectively, P = 0.049). Seventy-seven and 92% of the patients in the BET and ESS groups, respectively, considered the anesthesia and pain relief to be sufficient. Patients from both the BET and ESS groups were almost devoid of pain 1 to 2 hours postoperatively (0.8 ± 0.2 and 1.4 ± 0.3, respectively). In total, 12 of 13 patients in the BET group, and all 12 patients in the ESS group, would choose local anesthesia with sedation and analgesia if they needed to undergo the same procedure again.

Conclusion: BET is a safe and feasible procedure under monitored anesthesia care, including local anesthesia along with sedation and analgesia. There is need for further methodological improvement to reduce pain and discomfort during the operation.

Eustachian Tube Mucosal Inflammation Scale Validation Based on Digital Video Images.

Otol Neurotol 2015 Dec;36(10):1748-52

*Department of Otorhinolaryngology, Tampere University Hospital and the University of Tampere, Tampere, Finland †Department of Otolaryngology, Boston Children's Hospital and Harvard Medical School, Boston, Massachusetts, U.S.A. ‡Department of Otorhinolaryngology, Helsinki University Hospital, Helsinki, Finland.

Background: The most common cause for Eustachian tube dilatory dysfunction is mucosal inflammation. The aim of this study was to validate a scale for Eustachian tube mucosal inflammation, based on digital video clips obtained during diagnostic rigid endoscopy.

Methods: A previously described four-step scale for grading the degree of inflammation of the mucosa of the Eustachian tube lumen was used for this validation study. A tutorial for use of the scale, including static images and 10 second video clips, was presented to 26 clinicians with various levels of experience. Each clinician then reviewed 35 short digital video samples of Eustachian tubes from patients and rated the degree of inflammation. A subset of the clinicians performed a second rating of the same video clips at a subsequent time. Statistical analysis of the ratings provided inter- and intrarater reliability scores.

Results: Twenty-six clinicians with various levels of experience rated a total of 35 videos. Thirteen clinicians rated the videos twice. The overall correlation coefficient for the rating of inflammation severity was relatively good (0.74, 95% confidence interval, 0.72-0.76). The intralevel correlation coefficient for intrarater reliability was high (0.86). For those who rated videos twice, the intralevel correlation coefficient improved after the first rating (0.73, to 0.76), but improvement was not statistically significant.

Conclusion: The inflammation scale used for Eustachian tube mucosal inflammation is reliable and this scale can be used with a high level of consistency by clinicians with various levels of experience.
