“…In our study, postoperative CAP and SIR scores were significantly better than preoperative scores, although there were significant differences between CCD and control groups in CAP, SIR scores and aided hearing thresholds. It demonstrates that cochlear implantation is an effective treatment for patients with and without CCD, with hearing and speech outcomes in CCD patients being inferior compared to those without CCD, which is consistent with existing reports ( Beltrame et al., 2013 , Catli et al., 2015 , Pradhananga et al., 2015 ). The follow-up duration in our study ranged from 18 to 64 months, making observing the time course of auditory perception and speech ability along time somewhat difficult.…”

ObjectiveA common cavity deformity (CCD) is a deformed inner ear in which the cochlea and vestibule are confluent forming a common rudimentary cystic cavity that results in profound hearing loss. There are few studies paying attention to common cavity. Our group is engrossed in observing the improvement of auditory and verbal abilities in children who have received cochlear implantation (CI), and comparing these targets between children with common cavity and normal inner ear structure.Material and methodsA retrospective study was conducted in 12 patients with profound hearing loss that were divided into a common cavity group and a control group, six in each group matched in sex, age and time of implantation, based on inner ear structure. Categories of Auditory Performance (CAP) and speech intelligibility rating (SIR) scores and aided hearing thresholds were collected and compared between the two groups. All patients wore CI for more than 1 year at the Cochlear Center of Anhui Medical University from 2011 to 2015.ResultsPostoperative CAP and SIR scores were higher than before operation in both groups (p < 0.05), although the scores were lower in the CCD group than in the control group (p < 0.05). The aided threshold was also lower in the control group than in the CCD group (p < 0.05).ConclusionEven though audiological improvement in children with CCD was not as good as in those without CCD, CI provides benefits in auditory perception and communication skills in these children.

“…Several studies have shown audiological and speech benefits after CI surgery for IEM deformities, but these benefits are found to be inferior to those of CI surgery in patients with normal inner ears [8,9,13]. In general, several factors, such as age at implantation, cognitive ability, additional disability, residual hearing, parental participation, and the daily use of the cochlear implant audio processor, affect language development after CI [14].…”

“…Several studies have found that CI in patients with CC is effective and has hearing and speech benefits [7,8]. However, the audiological outcomes of CI in patients with CC were found to be not good as the other IEM [9]. The aim of this study is to present the management for a case of bilateral IEM associated with prelingual profound SNHL with radiological diagnosis of CA represented bilaterally.…”

Inner ear malformation is a congenital anomaly associated with prelingual sensory neural hearing loss in the pediatric population. This is a case report of bilateral radiologically diagnosed cochlear aplasia in a child who underwent unilateral left cochlear implantation with audiological results at one-year follow-up after surgery. Sixteen months after the cochlear implantation surgery, the child could produce 200 words and say a sentence with two words. In certain cases of inner ear malformation, the subgrouping of cystic cavity can be difficult and should not delay the trial of cochlear implant provided an acceptable anatomical appearance of the inner ear with cochleovestibular nerve existence and a proper electrode used for implantation.

“…This performance advantage may be due to customized electrodes in the TSLA group, which may more efficiently stimulate spiral ganglion cells due to the better position in the cochlea. For both subject groups, the improvement in CAP scores was greater than in SIR scores, consistent with previous studies . This suggests that language development may be slower than auditory development in CCD CI patients.…”

“…For both subject groups, the improvement in CAP scores was greater than in SIR scores, consistent with previous studies. 21 This suggests that language development may be slower than auditory development in CCD CI patients. Given that CCD performance may continue to improve 3 to 5 years after implantation, 18 more longterm follow-up is needed for CCD CI patients with greater consideration of surgical approaches and the use of standard or customized electrodes.…”
