Stapedotomy experience at Hospital del Salvador between 2012 and 2018

Abstract

Introduction: Otosclerosis is a presumable metabolic disease that determines ossi­cular chain fixation. Stapedotomy with prosthesis installation is the surgery of choice for this pathology at present. Aim: To describe the experience and results of the surgical treatment of patients with otosclerosis in the Hospital del Salvador between 2012 and 2018. Material and methods: Clinical records were reviewed of patients treated surgically in our department from January 2012 to September 2018 with suspicion of otosclerosis. Results: A total of 52 surgeries were performed in 45 patients, 42 via microscopy and 10 via endoscopy, two models of prostheses were used Schuknecht - type piston and wire y Stapes-Prothesen. The pure tonal average (PTP) by pre-surgical air was 65 dB, with an average air gap (gap) of 36 dB. The average post-surgical PTP was 35 dB with an average gap of 9 db, achieving on average an improvement of 31 dB in the airway and 27 dB of gap closure. 92% of the patients who underwent surgery improved with respect to the postoperative gap. Conclusion: The stapedotomy is an intervention that although not free of complica­tions, has been shown to be safe and have good hearing results in most patients.
