Minimally invasive cochlear implantation with mastoidal three-layer flap technique

Area of Science:

• Otolaryngology
• Neurosurgery
• Surgical Innovation

Background:

• Cochlear implantation is a critical intervention for hearing restoration.
• Minimally invasive techniques are sought to improve surgical efficiency and patient recovery.
• Traditional cochlear implantation methods may involve longer operative times and potential complications.

Purpose of the Study:

• To present and assess a novel minimally invasive cochlear implantation technique.
• To evaluate the efficacy and safety of the three-layer flap (TLF) approach.
• To compare the TLF technique with classical cochlear implantation methods.

Main Methods:

• A prospective clinical study was conducted at a tertiary referral center.
• The study included 55 patients (32 males, 16 females; age 1-51 years).
• Thirty-nine patients underwent cochlear implantation using the TLF technique, incorporating the superficial musculoaponeurotic system (SMAS) as a distinct flap layer.

Main Results:

• The three-layer flap (TLF) technique demonstrated no major complications, including flap-related issues or device migration.
• Mean operative time for the TLF technique was significantly reduced (66 minutes) compared to the classical technique (92 minutes) (p = 0.0001).
• The TLF technique ensured complete and secure coverage of the receiver-stimulator.

Conclusions:

• The three-layer flap (TLF) technique provides a safe and effective method for cochlear implantation.
• This approach allows for complete receiver-stimulator coverage and secure fixation without additional procedures.
• The TLF technique significantly reduces operative time, enhancing surgical efficiency in cochlear implantation.
