About
The objective of this study is to demonstrate that balloon dilation of the Eustachian tubes can be done successfully for treatment of chronic dilatory Eustachian tube dysfunction under local anesthesia with acceptable patient discomfort levels.
Full description
This study is a prospective, non-significant risk, multi-center trial of patients with Eustachian tube dysfunction who are refractory to medical management. Patients will undergo balloon dilation of the Eustachian tubes in the office under local anesthesia. We will assess assess the peri-procedural and post-procedure pain levels, and determine the proportion of subjects experiencing normalization of tympanometry and improvement in quality of of life at 6 weeks, 12 weeks, and 52 weeks post-treatment.

Persistent ETD as defined by patient-reported symptoms of ETD (including pressure and/or pain and/or clogged and/or muffled sensation in the affected ear(s)) for no less than 12 weeks prior to enrollment, and at least one of the following confirmatory indicators of persistent ETD no less than 12 weeks prior to enrollment B1: Confirmation from referring physician that the subject has experienced persistent ETD symptoms (including pressure and/or pain and/or clogged and or muffled sensation in the affected ear(s)) during an office visit no less than 12 weeks prior to enrollment. Persistent symptoms must be confirmed as not waxing and waning. OR B2: Documented evidence in the ENT physician records that the subject has experienced persistent ETD symptoms (including pressure and/or pain and/or clogged and/or muffled sensation in the affected ear(s)) during an office visit no less than 12 weeks prior to enrollment. Persistent symptoms must be confirmed as not waxing and waning. OR B3: Type B or Type C tympanogram in at least one ear no less than 12 weeks prior to enrollment. OR B4: Otoscopic exam demonstrating TM retraction and/or middle ear fluid no less than 12 weeks prior to enrollment.
Failure of appropriate medical management consisting of either a minimum of 4 weeks of continuous daily usage of any intranasal steroid spray (INS) or a minimum of one completed course of an oral steroid, per the investigator's choice. The failed medical management may occur any time within 90 days prior to study enrollment.
A positive diagnosis of persistent (i.e. not waxing and waning) ETD, as confirmed with both of the following:
D1: Abnormal tympanometry (defined as either Type B or Type C) after failed medical management and within 14 days of study enrollment D2: Symptomatic dysfunction as documented by a Eustachian Tube Dysfunction Questionnaire (ETDQ-7) mean item score ≥ 2.1 after failed medical management
Absence of internal carotid artery (ICA) dehiscence into the ET lumen on both sides as confirmed by a computed tomography (CT scan) including temporal bone - to include paranasal sinuses when clinically appropriate
