RESUMEN
PURPOSE: To compare the hearing results and clinical safety of patients undergoing stapes surgery with conventional technique and diode laser. METHODS: Retrospective observational study, which included patients treated with primary stapes surgery performed between January 2009 and January 2020. Three audiometric measurements (PTA, GAP and SDS) were evaluated as main results, evaluated by analysis of covariance (controlling the preoperative value). Intraoperative and postoperative complications were also analyzed. Outcomes were measured 6 months (± 1 month) after surgery. RESULTS: 153 cases were included, 97 operated with conventional technique and 56 with laser technique. Postoperative GAP ≤ 10 dB was obtained in 85.6% of the total sample, 82.5% in the conventional technique and 91.1% in the laser technique. Analysis of covariance showed no significant differences in the three surgery outcomes between the two groups (PTA, p = 0.277; GAP, p = 0.509 and SDS, p = 0.530). Regarding surgical complications, sensorineural damage was higher in the conventional technique group (p = 0.05). On the other hand, there were four cases of facial paresis, all in the laser group, three of them with the 980 nm laser. CONCLUSIONS: Stapedotomy offered a high percentage of hearing success in the two groups studied. There were no significant differences in audiometric result, but there was a differential presentation of complications, being more frequent sensorineural hearing loss in the conventional technique group and facial paresis in the laser group.

Objetivo: evaluar las diferencias en la percepción musical entre la estimulación sonora eléctrica frente a la acústica. Materiales y métodos: se recolectó información de pacientes adultos con implante coclear unilateral, con oído contralateral sano o hipoacusia leve y con un tiempo de rehabilitación auditiva mayor a 12 meses. Se les aplicaron escalas de reconocimiento musical, de calidad de vida Glasgow Benefit Inventory (GBI), identificación de tono, ritmo, instrumentos y canciones. Resultados y conclusiones: se recolectaron datos de 6 pacientes con edades entre 37-73 años, promedio de tonos puros (PTA, por sus siglas en inglés) en oído sano <40 dB y porcentaje de máxima discriminación (SDS, por sus siglas en inglés): 100 % sin cambios en el postoperatorio. El oído implantado con un rango de PTA postoperatorio entre 40 y 58,3 dB y SDS entre 70-90 %. Se aplicó la escala GBI, en donde la mayoría de los pacientes obtuvieron resultados positivos con un rango entre +41 y -13. La mayoría de los pacientes aumentaron la frecuencia de escucha musical post-implantación (4/6 pacientes). La mitad de los pacientes reportaron mejoría en el papel que desempeña la música en sus vidas. En el reconocimiento del tono y del ritmo en el oído implantado se encontraron resultados similares posterior a la implantación con respecto al oído sano, con medianas de 17/20 frente a 16/20 en patrones tonales y 18,5/20 frente a 18/20 en patrones rítmicos. El reconocimiento de las canciones fue mejor con la letra que sin la letra en el oído implantado (8/8 frente a 7/8, respectivamente). El reconocimiento de instrumentos en el oído implantado fue 4,5/8 instrumentos frente a 7,5/8 en el oído sano.
Objective: To evaluate the differences in musical perception between electrical and acoustic sound stimulation. Materials and methods: Adult patients with unilateral cochlear implant, healthy or mild hearing loss in the contralateral ear and rehabilitation time greater than 12 months were evaluated. Musical recognition scales, quality of life Glasgow Benefit Inventory (GBI) and identification of tone, rhythm, instruments, and songs were applied. Results and conclusions: 6 patients were collected, ages between 37-73 years, healthy ear with a pure tone average (PTA) <40 dB, speech discrimination score (SDS): 100 % without changes in the postoperative period. The Implanted ear with average PTA between 4058.3 dB and SDS between 70-90 % post-implantation. The GBI scale was applied where most of the patients obtained positive results, with a range between +41 and -13. Most of the patients improved the frequency of music-listening after implantation (4/6 patients). Half of the patients reported improvement in the role music plays in their lives. In the recognition of the tone and rhythm in the implanted ear, similar results were found after the implantation with respect to the healthy ear, with medians of 17/20 vs. 16/20 in tonal patterns and 18.5/20 vs. 18/20 in rhythmic patterns. The recognition of the songs was better with the lyrics than without the lyrics in the implanted ear, with medians of 8/8 vs. 7/8. The recognition of instruments in the implanted ear was 4.5/8 vs. 7.5/8 in the healthy ear.
