Summary: | Aims: To describe and evaluate a minimally invasive cochlear implantation approach using mastoidal three-layer flap (TLF) technique. Methods: We conducted a prospective clinical study at a tertiary referral center. The study population comprised 32 males and 16 females, with an age range of 1–51 years. Thirty-nine patients were operated on using the TLF technique and 9 patients were operated on using a classical cochlear implantation technique. The TLF technique was based on using the superficial musculoaponeurotic system (SMAS) as an additional, strong flap layer. The TLF, with 3 different pedicules, comprised an anteriorly based 4-cm skin flap, a superiorly based temporomastoidal flap, which included the SMAS, and an anteriorly based periostal Palva type flap in the same mastoidal area. Results: No major complications, including flap-wound problems and receiver-stimulator migration or extrusion, were encountered. The mean operation time was 66 min in the TLF population and 92 min in the classical operation population, which shows a statistically significant difference noted in the time of operation (p = 0.0001). Conclusion: The TLF cochlear implantation enables complete receiver-stimulator coverage and safe fixation without any additional procedures, while allowing reduced operation time. |
