<p>Cochlear Implantation in Mondini Syndrome Using FORM 19 MED-EL Electrodes at Al Zahrawi Hospital, Libya: a prospective observational study</p> <p>Dr Abdussalam Mohamed Jahan</p> <p>A. Professor of ENT, Al Zahrawi hospital, Libya.</p> <p>Abstract</p> <p>Background: Mondini syndrome is a congenital inner ear malformation commonly associated with severe to profound sensorineural hearing loss and may pose surgical challenges during cochlear implantation. The FORM 19 MED-EL electrode is designed to allow effective insertion in malformed cochleae while preserving delicate inner ear structures.</p> <p>Objective: To evaluate the surgical and early auditory outcomes of cochlear implantation in patients with Mondini syndrome using FORM 19 MED-EL electrodes at Al Zahrawi Hospital, Libya.</p> <p>Methods: This prospective study included Five patients, aged from 2 to 5-year-old, diagnosed with Mondini malformation who underwent cochlear implantation using FORM 19 MED-EL electrodes from April 2023 to March 2025 at Al Zahrawi private Hospital, Misurata city, Libya. Surgical findings, cerebrospinal fluid gusher, electrode insertion success, postoperative complications, and early auditory outcomes were evaluated.</p> <p>Results: Successful electrode insertion was achieved in four patients. One patient was difficult to insert. Intraoperative cerebrospinal fluid gusher was encountered in all cases and managed successfully without major complications. Early postoperative auditory responses and device activation outcomes were satisfactory in most patients.</p> <p>Conclusion: Cochlear implantation using FORM 19 MED-EL electrodes in patients with Mondini syndrome is safe and effective. The electrode design may facilitate successful implantation in malformed cochleae and provide favorable early hearing outcomes. This study highlights the growing experience of cochlear implantation surgery at Zahrawi Hospital.</p> <p>Key words: cochlear implant, Mondini , FORM 19 electrode</p>
