Impact on Quality of Life After Mastoid Obliteration

Objectives/Hypothesis: To understand the long-term impact on quality of life (QOL) in patients undergoing mastoid obliteration surgery for a chronically draining cavity, using the Glascow Benefit Inventory (GBI) QOL survey, and to correlate these findings to perceived changes in drainage and hearing. Study Design: Retrospective chart review. Methods: Adult patients undergoing mastoid obliteration and restoration of the middle ear space with cartilage reconstruction of the tympanic membrane, with at least 3-year follow-up, were contacted by phone to solicit participation. Those who agreed to participate were mailed the GBI and consent documents with a prepaid self-addressed envelope. Results: Of 80 patients meeting the inclusion criteria, 37 were successfully contacted and agreed to participate, yielding 23 returned questionnaires. The vast majority (19 of 23; 83%) reported improved QOL after surgery, with the most positive effects seen on confidence and social situations, and patients experiencing less inconvenience, self-consciousness, and embarrassment. Eighty-three percent reported a perceived improvement in hearing; 74% reported an improvement in drainage. Over 90% would recommend the procedure to a family member. The average score on the GBI was 28.9, and a two-tailed one-sample t test showed that mastoid obliteration significantly improved QOL in our patients (t = 4.65, P < .001). There was a fairly good correlation between the perceived improvement in QOL with improvement in hearing and/or drainage. Conclusions: The GBI is a valuable tool for evaluating patient satisfaction after revision surgery for a draining cavity. This information is helpful in understanding the impact of a draining cavity on an individual's life and may be beneficial in preoperative selection and counseling.
