Cochlear Implantation in Extraordinary Cases.

Area of Science:

• Otolaryngology
• Neurosurgery
• Genetics

Background:

• Cochlear implantation is a standard procedure but presents challenges in unusual cases.
• Conditions like Seckel syndrome, congenital aural atresia, and posterior fossa arachnoid cysts pose surgical dilemmas.
• These rare conditions require careful consideration for successful cochlear implantation.

Purpose of the Study:

• To evaluate the efficacy of cochlear implantation in patients with rare and complex conditions.
• To demonstrate the feasibility of simultaneous retrosigmoid approach and cochlear implantation.
• To report successful audiological outcomes in challenging cochlear implant cases.

Main Methods:

• Case report of three patients undergoing cochlear implantation.
• Case 1: Seckel syndrome with complete atrioventricular block and pacemaker.
• Case 2: Posterior fossa arachnoid cyst treated with simultaneous retrosigmoid cyst removal and cochlear implantation.
• Case 3: Cochlear implantation in a patient with congenital aural atresia.

Main Results:

• Successful cochlear implantation with full electrode insertion in all three cases.
• Good audiological outcomes were achieved post-implantation.
• Delayed facial paralysis in the arachnoid cyst case resolved spontaneously.

Conclusions:

• Cochlear implantation is an efficient option for Seckel syndrome, congenital aural atresia, and posterior fossa arachnoid cyst.
• Simultaneous retrosigmoid approach and cochlear implantation is a viable surgical option.
• Successful audiological rehabilitation is achievable even in complex otological cases.
