Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Chronic Eustachian Salpingitis Device: Balloon dilation of the Eustachian tubes Not Applicable

Detailed 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.

Experimental: Treatment arm
Balloon dilation of the Eustachian Tube(s) with Acclarent Aera Balloon
Device: Balloon dilation of the Eustachian tubes

Primary Outcome Measures :
  1. Visual Pain Assessment Scale to describe procedural pain [ Time Frame: during procedure ]
    Assess peri-procedural pain levels with a visual pain assessment scale. The scale has numbering from 0-10 with associated visual pictures that correspond to the degree of pain. Participants will number their pain level and describe the location of pain (ear, nose, forehead, jaw, teeth).

  2. Visual Pain Assessment Scale to describe postoperative pain [ Time Frame: 2 weeks after procedure ]
    Assess post-procedural pain levels with a visual pain assessment scale. The scale has numbering from 0-10 with associated visual pictures that correspond to the degree of pain. Participants will number their pain level and describe the location of pain (ear, nose, forehead, jaw, teeth).

  3. Visual Pain Assessment Scale to describe postoperative pain [ Time Frame: 6 weeks after procedure ]
    Assess post-procedural pain levels with a visual pain assessment scale. The scale has numbering from 0-10 with associated visual pictures that correspond to the degree of pain. Participants will number their pain level and describe the location of pain (ear, nose, forehead, jaw, teeth).

  4. Visual Pain Assessment Scale to describe postoperative pain [ Time Frame: 52 weeks after procedure ]
    Assess post-procedural pain levels with a visual pain assessment scale. The scale has numbering from 0-10 with associated visual pictures that correspond to the degree of pain. Participants will number their pain level and describe the location of pain (ear, nose, forehead, jaw, teeth).


Secondary Outcome Measures :
  1. Tympanometry - an objective measure of the negative pressure in the middle ear [ Time Frame: 6 weeks after procedure ]
    proportion of subjects experiencing normalization of tympanometry post-treatment, indicating improvement or resolution in the negative pressure in the middle ear.

  2. Tympanometry - an objective measure of the negative pressure in the middle ear [ Time Frame: 52 weeks after procedure ]
    proportion of subjects experiencing normalization of tympanometry post-treatment, indicating improvement or resolution in the negative pressure in the middle ear.


Other Outcome Measures:
  1. Quality of life assessment using the ETDQ-7 questionnaire [ Time Frame: 6 weeks after procedure ]
    Determine the proportion of subjects achieving improvement of 0.5 points at 6 weeks post-treatment, indicating significant improvement in the quality of life with respect to symptoms of Eustachian tube dysfunction.

  2. Quality of life assessment using the ETDQ-7 questionnaire [ Time Frame: 52 weeks after procedure ]
    Determine the proportion of subjects achieving improvement of 0.5 points at 6 weeks post-treatment, indicating significant improvement in the quality of life with respect to symptoms of Eustachian tube dysfunction.

Ages Eligible for Study:   22 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  1. Adult male or female aged 22 years and older
  2. 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.
  3. 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.
  4. A positive diagnosis of persistent (i.e. not waxing and waning) ETD, as confirmed with both of the following:
