“…The most widely used criteria for candidacy include bilateral severe-to-profound sensorineural hearing loss (SNHL), the optimal age should be between 12 months and 5 years but younger ages can also be the candidate, lack of improvement in hearing and speech benefits from hearing aids after a 3 months usage, the family of the patient will promote the surgery and postoperative rehabilitation, the family and the patients have convenient hope for the outcome of the surgery and are available for rehabilitation and education and also there should be no contraindications for surgery (4). If the audimetric candidacy is described distinctly, it ranges from severe to profound SNHL for ages from 2 to 17 years and profound SNHL for ages from 12 to 24 months, that is for children aged 12-24 months, the pure-tone average (PTA) should equal or exceed 90 dB (3).…”

“…For postlingual patients, some additional criteria can be as postlingual deafness of all ages, no or little benefit from hearing aid amplification with preoperative scores for speech recognition test is lower than 50% in ear to be implanted and 60% bilaterally in best-aided condition (2,4). Also, emotional and psychological stability with good motivation is important for candidacy.…”

“…Another affecting factor for the outcome is the onset age and duration of hearing loss. Generally, an early onset and a long duration of hearing loss have poorer outcomes for postlingual patients (4,5).…”

Cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf. CI represents the current treatment for patients affected by profound sensorineural hearing loss (SNHL). At first times, only deaf adults were considered to be candidates for a CI; however, with the development of technology and gained experience by pshycians, indications for cochlear implantation have been expanded. Today, CIs are implanted also in children and broader indications are followed. There are, however, a number of patients who are potential candidates for CI but do not completely fulfill the current indications. Residual hearing and duration of deafness represent prognostic indicators for CI performance; however, prelingually deafened adults and children with residual hearing are still point at issue. Anatomical variations such as cochlear malformation, ossification and chronic otitis media still represent a contraindication to CI for some surgeons. Although the technology for cochlear implant surgery is advancing everyday, there may be several complications related to the device or operation and some of them can be healed only with medical therapy but some are serious enough to process to reimplantation. In this article the indications and contraindications for cochlear implant candidates and complications that may occur during or after the operation were reviewed under the light of the literature.

Objective: The objective of this study was to examine whether cochlear implantation using the round window (RW) route versus cochleostomy achieves comparable electrode impedance and hearing results. Methods: This retrospective analysis included 40 patients receiving a cochlear implant (REZ-1): 20 using the RW approach and the remaining 20 using cochleostomy. Electrode impedance and tone, vowel, consonant, disyllable and sentence perception were measured during and after the implantation. Results: Electrode impedance did not differ significantly between the 2 groups at any time points [F(1, 38) = 1.84; p = 0.184]: 1.87, 5.16, 6.47 and 6.70 kΩ in the RW group versus 2.86, 5.33, 6.92 and 8.16 kΩ in the cochleostomy group at 0, 1, 3 and 12 months, respectively. There was no significant difference between the RW and cochleostomy groups for tone (77.50 vs. 80.50%; p = 0.472), vowel (77.70 vs. 78.65%; p = 0.760), consonant (75.50 vs. 78.25%; p = 0.443), disyllable (78.60 vs. 81.50%; p = 0.317) and sentence (50.90 vs. 52.50%; p = 0.684) perception at 12 months. Conclusion: The RW approach is comparable to cochleostomy in electrode placement as reflected by impedance and function as reflected by tone, vowel, consonant, disyllable and sentence perception.
