Conditions

Eustachian Tube Dysfunction

Brief summary

A prospective, multicenter, registry of patients undergoing balloon dilation of the Eustachian tubes (ET).

Detailed description

This is a prospective, multicenter, single-arm, postmarket registry enrolling up to 300 participants who are planning to undergo balloon dilation of the Eustachian tubes for treatment of chronic/persistent Eustachian tube dysfunction (ETD). Procedural information will be collect as well as efficacy and safety data through 6 months post procedure.

Interventions

Unilateral or bilateral balloon dilation of the Eustachian tube using the FDA-cleared XprESS ENT Dilation System

Inclusion criteria

* Be at least 18 years old * Have been diagnosed with persistent/chronic Eustachian tube dysfunction (duration 3 months or more) * Be a candidate for unilateral or bilateral Eustachian tube balloon dilation using the XprESS device * Be able to read and understand English * Be willing and able to provide informed consent * Be willing to comply with the protocol requirements

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Change in mean Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score6 MonthsChange from baseline to follow-up in the mean overall ETDQ-7 score. The ETDQ-7 is a validated 7-item patient-reported questionnaire reporting the presence and severity of symptoms associated with Eustachian tube dysfunction. Each item is scored from 1 (normal) to 7 (severe). The overall score is the mean score of the 7 items.
Complication rate6 MonthsPercentage of participants who experience 1 or more serious adverse events that are related to the device and/or procedure.

Secondary

MeasureTime frameDescription
Revision Eustachian tube dilation6 MonthsPercentage of participants who require revision dilation on an ear that was treated in the initial procedure.
Surgical interventions6 MonthsPercentage of participants requiring surgical ear intervention (other than balloon dilation) on an ear that was treated in the initial procedure but has recurrent or continuing ETD symptoms.
Participant satisfaction: Proportion of participants indicating satisfaction and willing to recommend the procedure to friends or family6 MonthsPercentage of participants indicating satisfaction and willing to recommend the procedure to friends or family.
Change in work productivity/activity impairment6 MonthsParticipants complete the validated Work Productivity and Activity Impairment (WPAI) at baseline and 6 month follow-up. The questionnaire consists of 6 questions that evaluate absenteeism, presenteeism, work productivity loss, and activity impairment over the previous week. Results are expressed as the percentage of impairment from 0 to 100, for which higher numbers indicate worse outcomes (ie, greater impairment and less productivity). Absenteeism is calculated by dividing the number of hours missed by the sum of the numbers of hours missed plus the number of hours worked. Presenteeism, is calculated by dividing the response to productivity at work question by 10, while activity impairment is calculated by dividing the response to the ability to carry out daily activities question by 10. Finally, the overall work impairment/productivity loss is calculated as the sum of absenteeism and the product of presenteeism and time at work.
Procedural informationProcedure through 6-week follow-upDetails of the balloon dilation procedure, including setting, anesthesia, technical success, concomitant procedures, procedure/device-related adverse events, and recovery time.
Improvement in tympanogram6 MonthsPercentage of participants with an abnormal tympanogram (type B or C) at baseline who have a normal (type A) or improved (type B to type C) tympanogram at follow-up.
Improvement in ability to perform a Valsalva maneuver6 MonthsPercentage of participants unable to perform the Valsalva maneuver (negative) at baseline who are able to perform the maneuver (positive) at follow-up.
Improvement in tympanic membrane position6 MonthsPercentage of participants with a retracted tympanic membrane at baseline who have a normal tympanic membrane position at follow-up.
Change from baseline in chronic rhinosinusitis symptoms6 MonthsParticipants will complete the validated 22-item SinoNasal Outcomes Test (SNOT-22) to evaluate change in chronic rhinosinusitis symptoms. Each of the 22 symptoms on the questionnaire are rated by the participant from 0 (no problem) to 5 (bad). A sum of the 22 item scores provides the overall score, which can range from 0 to 110.
Minimal clinically important difference in ETDQ-7 score6 MonthsPercentage of participants achieving the minimal clinical important difference in overall ETDQ-7 score (reduction from baseline of 0.5 points or more). The ETDQ-7 is a validated 7-item patient-reported questionnaire reporting the presence and severity of symptoms associated with Eustachian tube dysfunction. Each item is scored from 1 (normal) to 7 (severe). The overall score is the mean score of the 7 items.
