title: Cartilage island on stapes: autologous PORP in the hypoventilated middle ear.
abstract: The most common technique in sound restoration of the middle ear is prosthetic surgery. Hypoventilation of the middle ear may cause adhesive otitis or atelectasis resulting in a higher risk of prosthetic extrusion rate and recurrence of the underlying cholesteatoma. We report long-term results using an island of tragal cartilage as an autologous PORP in selected patients with poor middle ear ventilation. Retrospective chart reviews were performed for procedures involving 52 patients between year 2000 and 2009. All patients that underwent surgery using tragal cartilage interposed between the suprastructure of the stapes and the tympanic membrane were included in this study. Audiological parameters using four frequencies, 0.5, 1, 2 and 3 kHz, according to AAO-HNS guidelines, were assessed pre-and postoperatively. The hearing results on different PTA frequencies were also investigated. We report long-term follow-up of patients with hypoventilated middle ear with a success rate of 71% (ABG <20%). With regards to the ABG, the low frequency component (5 and 1 kHz) showed a significantly (p < 0.05) larger improvement of mean values after surgery as compared to the high-frequency component (2 and 3 kHz). Cartilage island PORP on stapes is a stable and efficient method for selected patients with chronic middle ear disease.
