Endoscopic Rosette Cartilage Inlay-Onlay Myringoplasty: A 1-Year Prospective Study

Since 1952, myringoplasty has evolved with various surgical techniques, including overlay, underlay, sandwich, pegging, rosette, and plugging. Overlay and underlay methods are most commonly used. In 1998, Eavey introduced the cartilage and perichondrium butterfly inlay myringoplasty, designed for small to medium-sized perforation closure, offering practical advantages such as reduced surgical time and improved hearing outcomes. A one-year prospective study (September 2022 to September 2023) in a tertiary care hospital in India involved 30 patients aged 9-52 years with inactive small central perforations. Pre-operative pure tone audiometry (PTA) results were required to be no higher than 35 dB conductive hearing loss. General or local anesthesia was used based on the patient's age. The surgical technique involved visualizing the perforation, graft preparation, and transcanal insertion. Among the 30 patients, the graft uptake rate was 100% at 3 months and 93.33% at 6 months. Pre-operative mean PTA was 29.76 dB, which decreased to 25.03 dB post-operatively, with a statistically significant air-bone gap closure of 4.73 dB. Cartilage rosette inlay-onlay myringoplasty offers an effective solution for small to medium-sized perforations, achieving high success rates (93.33%). This technique is associated with reduced surgical time, suitability for day care surgery, and minimal scarring, making it a valuable addition to routine clinical practice.
