RESUMO
OBJECTIVE: Assess clinical and functional outcomes of a modified palisade cartilage-perichondrium graft myringoplasty under local in an office setting. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care facility. PATIENTS: Patients with a tympanic membrane perforation presenting between March 2013 and October 2017. Inclusion criteria included ageâ¯≥â¯7â¯years, entire perforation margin visualized through a transcanal view, and the ability to lie supine for up to 45â¯min. Exclusion criteria included a conductive hearing loss larger than expected, and presence of active infection. INTERVENTION: In-office modified myringoplasty technique under local anesthesia without sedation. MAIN OUTCOME MEASURES: Complete perforation closure rate and audiometric outcomes. RESULTS: 250 patients underwent the procedure, of whom 13 had bilateral sequential procedures (total 263 ears). Of those, 197 were primary and 66 revision. Average age was 46.3â¯years. Perforation sizes were categorized as small (32), moderate (109), large (78), and subtotal (44). Complete perforation closure was evident in 219 of the 250 cases (88%). Preoperative mean air pure tone average (PTA) was 56.7â¯dB and mean bone PTA was 27.5â¯dB (pre-operative ABG 29.2â¯dB). AC-PTA significantly improved to 35.0â¯dB (pâ¯<â¯0.0001), and ABG to 9.6â¯dB (pâ¯<â¯0.0001). Only subtotal perforations showed a statistically significant negative relationship with outcome (pâ¯=â¯0.04). CONCLUSION: The modified palisade cartilage-perichondrium graft myringoplasty under local anesthetic is a highly successful procedure well tolerated by adult and pediatric patients with variable perforation sizes. This may have significant potential patient benefits, as well as cost savings to the health care system.
