Complications in cochlear implant surgery.

Gheorghe DC, Zamfir-Chiru-Anton A - J Med Life (2015 Jul-Sep)

Bottom Line: For the last 6 years, cochlear implantation has become a standard practice in our department.The number of patients rose from 5 to 21/ year.Using multiple types of cochlear implants and indicating the surgery also to malformed inner ears led to the encounter of some complications. to present the surgical complications from our department. all the patients admitted and operated in our clinic have been reviewed. 9 complications (8,86%) have occurred: the impossibility of establishing a reliable cochleostomy (due to ossification), air in the cochlea through lack of sealing of the cochleostomy (exteriorization of the electrode array), cochlear implant postoperative migration from its bed, weak hearing discrimination due to "double electrodes" in the scala tympani, gusher. cochlear implanting needs to respect the technical steps of the surgery and the best technical/ tactical solution has to be found to whatever complications arise in complex or malformed cases!

ABSTRACT

Unlabelled: For the last 6 years, cochlear implantation has become a standard practice in our department. The number of patients rose from 5 to 21/ year. Using multiple types of cochlear implants and indicating the surgery also to malformed inner ears led to the encounter of some complications.

Objective: to present the surgical complications from our department.

Material: all the patients admitted and operated in our clinic have been reviewed.

Results: 9 complications (8,86%) have occurred: the impossibility of establishing a reliable cochleostomy (due to ossification), air in the cochlea through lack of sealing of the cochleostomy (exteriorization of the electrode array), cochlear implant postoperative migration from its bed, weak hearing discrimination due to "double electrodes" in the scala tympani, gusher.

Conclusions: cochlear implanting needs to respect the technical steps of the surgery and the best technical/ tactical solution has to be found to whatever complications arise in complex or malformed cases!

Figure 5: Gusher cases (left – incomplete partition type III; right – apparently normal cochleas)

Mentions: 2 gusher cases were encountered in our cochlear implant patients. One of them was expected preoperatively because of a type III incomplete partition of the cochlea (X-linked deafness). The other one showed no abnormality on imagistics and was an intraoperative surprise (Fig. 5). The first patient was solved by means of a tight cochleostomy and thoroughly packing with muscular pieces around the electrode array. No vestibular symptoms were recorded postoperatively. The second one benefited from the “cork style” of the electrode array at its external base, which perfectly occluded the cochleostomy and efficiently prevented any perilymph leak.
