Abstract

Objects: Study characteristic of epidemic, clinical and operation of cochlear implant in Sai gon ENT hospital. Subjects and study methods: 30 patients (36 implanted ears), satisfying the criteria for cochlear implant, were operated in Saigon ENT hospital, from 2015-2024. With methods: A prospective and clinical intervention. Results and discussion: Male gender (66,67%). Implant age: Over 7 years of age (63,33%), age of implant is old, for both subjective and objective reasons. Causes of hearing loss: Innate is majority (70%). Drug poisoning (33,3%) of acquired deafness. Wearing a pre-implant hearing aid: 88,9%, which facilitated post-implant speech therapy. Implanted ear: Right side (44,44%) and 16,67% for both side. Electrode insertion: Cochleostomy is 80,56%, depending on the technique of each surgeon. Inserted electrodes array: 94,44% were fully inserted; two cases (5,56%) of the electrodes were not fully inserted (one of was suspected of fibrosis after trauma and the unknown anorther). Average operation time: 1 ear, <120 minutes 58,3% (<90 minutes, 33,3%); 2 ears, 180-240 minutes (66,7%). Complications: without any severe complications during or after surgery, there were 1 case with slow wound healing but then healed well after 3 weeks, 1 case with taste disorder and recovered after 6 months, same ratio 2.8%. Hospitalize: 96,7% discharged on day 4 after surgery, early discharge cost savings. Conclusions: The implanted age is late, adequate hearing aids before implantation will facilitate speech therapy. Congenital deafness is majority, screening program is necessary for early diagnosis and timely intervention. Cochlear implant is safe, early discharge to save cost and the risk of nosocomial infection was decreased.
