“…Xia et al [13] did follow-up for 36 months of 21 patients with common cavity deformity who underwent cochlear implantation, the average free-field hearing threshold was higher, and the scores for the CAP, SIR, IT-MAIS, and closed-set/open-set auditory speech perception tests were lower than in the control group (p \ 0.05), which is similar to our results.…”

To report operative findings, postoperative course, and postimplantation performance in patients with cochlear malformations who underwent cochlear implantation. Seventeen patients with malformations which included enlarged vestibular aqueduct (n = 6), Mondini's dysplasia (n = 5) common cavity deformity (n = 3) and incomplete partition type 2 (n = 3) underwent cochlear implantation with Nucleus 22 straight array device at our center. Operative findings described facial nerve anatomy and cerebrospinal fluid leak. Standard tests of speech perception were used to evaluate the postoperative performance for each subject. Operative findings included cerebrospinal fluid leak (thirteen patients) all of which were repaired successfully with graft. None had abnormal facial nerve anatomy. No surgical complications occurred. All the patients except two with common cavity had complete insertion. Electrode thresholds and discomfort levels were variable for several months after implantation. All patients demonstrated improved performance after implantation. Patients with enlarged vestibular aqueduct fared better than patients with other inner ear malformations. Cochlear implantation can be a successful method of rehabilitation in patients with congenital deafness who have cochlear malformations.

“…Six CCD CI patients were implanted using the TFRA and seven were implanted using the TSLA, as in Xia et al 15 For the TSLA, the size of the labyrinthotomy in the lateral semicircular canal was approximately 1.0 3 4.0 mm and the labyrinthotomy was sealed using temporalis fascia and muscle. To further improve outcomes for CCD CI patients, customized electrode arrays were used in patients who were implanted using the TSLA.…”

“…5 A subsequent study showed that none of 18 CCD patients implanted using the single-slit labyrinthotomy approach exhibited CSF leak or meningitis after surgery. 15 The authors speculated that the size of the labyrinthotomy has no influence on the incidence of CSF gusher, which may be associated with a defective cribriform plate in the IAC. In the single-slit labyrinthotomy approach, the labyrinthotomy and the whole cavity is sealed with temporalis fascia and muscle to stop any CSF leakage.…”

“…In previous studies on CCD, the modified transmastoid labyrinthotomy (lateral semicircular canal approach) was used ( Beltrame et al., 2005 , Zarandy, 2008 ). Some scholars hold the opinion that conventional facial recess approach can be used when there is a residual structure of cochlea in the area of promontory, while the modified transmastoid labyrinthotomy can be selected when the cochlea cannot be distinguished from the common cavity structure ( Xia et al., 2015 ). The electrode array was inserted successfully by the modified transmastoid labyrinthotomy approach in all CCD cases in our study.…”

Cochlear implantation outcomes in children with common cavity deformity; a retrospective study

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.
