In children without a well-developed mastoid tip, care must be taken in making the incision to avoid damaging the descending portion of the facial nerve inferiorly, which may be located more laterally than in adults.for patients with planned bilateral cochlear implantation or a revision surgery) monopolar electrocautery contraindicated if a cochlear implant is already in place (eg.For cochlear implantation, a post auricular incision is designed approximately 3-5 mm just behind the post-auricular crease. A C-shaped post-auricular incision with a posterosuperior extension, is made down to the level of the superficial layer of the deep temporalis fascia.Double check ETT to assure that rotating head during surgery will not result in extubation.ETT taped to midline (RAE tube works well).Positioning: see General Considerations of Otologic Surgery.ANESTHESIA CONSIDERATIONS: see General Considerations of Otologic Surgery.MEDICATION: see OTOLOGY ANTIBIOTIC ADMINISTRATION GUIDELINES.Head trauma may result in damage to the cochlear implant.diathermy using electromagnetic radiation.ionizing radiation therapy over the cochlear implant.neurostimulation over the cochlear implant.The following therapies are contraindicated in patients with a cochlear implant.The magnet contained in the internal part of the cochlear implant needs to be surgically removed prior to any MRI undertaken by the patient (see cochlear implant manufacturer guidelines).Need for further surgeries, including removal and/or reimplantation of device.Complications of general anesthesia including heart attack, stroke, and death.Loss of residual acoustic hearing (expected).Wound infection, either immediate or delayed.Sign language and assist devices in home/workplace.Hearing amplification (although cochlear implant candidates typically receive little to no benefit from hearing aids).For children, performance usually improves with development of the child over many years.For adults, performance with a cochlear implant generally improves rapidly over a few months and then more slowly over several years.A wide range of hearing abilities is obtained with a cochlear implant, with most cochlear implant listeners able to obtain good open-set speech recognition in quiet.To provide hearing to deaf individuals via electrical stimulation of the cochlea.staged subtotal petrousectomy with closure of EAC.Previous canal-wall down tympanomastoidectomy.subtotal petrosectomy (involving plugging of the eustachian tube with muscle/fascia, obliteration of mastoid cavity, taking the canal wall down, and closure of the external auditory canal).Patients who continue to have ear infections or otorrhea despite ventilation tubes should have a staged implantation.Cochlear implantation is contraindicated during ongoing middle ear infections.should receive two doses of PCV-7 two or more months apart and then receive one dose of PPV-23 at least two months later.Children 24-59 months of age who have never received either PCV-7 or PPV-23.If they have just received PCV-7, they should wait at least two months before receiving PPV-23.one dose of the pneumococcal polysaccharide vaccine (PPV-23) (Pneumovax® 23).
