OBJECTIVES: To evaluate the clinical and audiological outcomes of percutaneous bone conduction device placement by minimally invasive Ponto surgery (MIPS).
METHODS: This was a retrospective descriptive study of patients who underwent MIPS from March-November 2019 at King Abdullah Ear Specialist Center, Collage of Medicine, King Saud University, Riyadh, Saudi Arabia. We reviewed all the clinical data of patients, including preoperative data, postoperative surgical results, and audiological performance (aided and unaided pure tone audiometry and aided and unaided speech tests).
RESULTS: A total of 9 patients with 10 implants were enrolled in this study. One patient underwent revision surgery because of infection and loss of the abutment. We followed the patients from 1-2 years, with a mean of 16.8 months. A significant difference was found between the unaided air conduction pure tone average, with a mean of 72.6±28.4 decibel (dB), and the postoperative aided threshold, with a mean of 20.8±12.2 dB/hectoliter (p=0.008), indicating a functional gain of 51.8 dB. The mean unaided speech discrimination at 65 dB sound pressure level was 34.7±24.8, which was significantly improved to 88.4±11.7 after implantation (p=0.007).
CONCLUSION: minimally invasive Ponto surgery is a suitable minimally invasive surgical method for bone-anchored implant placement. This technique has an advantage in terms of skin sensitivity, cosmetic outcomes, and operative duration.
