“…In this malformation, there was a complete labyrinthine aplasia to the point, where cochlear and vestibular elements are not formed. Due to the failure of the development of the otic vesicles to the absence of the formation of inner ear, this anomaly is described as an otocytic deformity and described as the extremely rare and the most severe inner ear abnormality (Quirk et al 2019). This deformity occurs after the formation of the otic vesicles is complete, because the semicircular canal is the first structure to be formed from the otic vesicles.…”

Highlight:High-resolution computed tomography (HRCT) scan has advantage for best image reconstruction and informative in interpreting images of the temporal bone.The essential primary aspect in HRCT of the temporal bone scan is technique and protocol. Abstract:The high-resolution computed tomography (HRCT) scan used in the 1980s offers a distinct advantage in interpreting images of the temporal bone. To obtain a right image reconstruction and to provide meaningful information, a certain degree of tilt is required so that radiologists and clinicians can get more real imaging information on structural abnormalities in the temporal bone and its soft tissue constituents. The technique or protocol in HRCT of the temporal bone becomes an essential primary aspect in presenting the analyzed structure, the assessment of the small form of the auditory bones, the soft tissue of the inner ear and the cranial nerves that pass through the temporal bone structure is much easier to analyze, of course with the help of reconstruction according to the HRCT protocol for temporal bone, however, soft tissue evaluation is preferable to MRI. In the end, the standard structure, congenital abnormalities and pathological problems in the temporal bone structure can be identified and informed to the clinician as a step to determine further treatment action.

“…Otic capsule and inner ear structures are completely formed at birth and remain stable in size over time, except for endolymphatic duct and sac which continues to grow until the age of four years old and the vestibular aqueduct which continues to develop until puberty [5,8]. An arrest at any one of these stages corresponds to a particular IEM (Table 2).…”

In the multidisciplinary management of patients with inner ear malformations (IEMs), the correct diagnosis makes the differences in terms of clinical and surgical treatment. The complex anatomical landscape of the inner ear, comprising several small structures, makes imaging of this region particularly challenging for general radiologists. Imaging techniques are important for identifying the presence and defining the type of IEM and the cochlear nerve condition. High-resolution magnetic resonance imaging (MRI) sequences and high-resolution computed tomography (HRCT) are the mainstay imaging techniques in this area. Dedicated MRI and HRCT protocols play an important role in the diagnosis and treatment of patients with inner ear disease. The most suitable technique should be selected depending on the clinical setting. However, in cases of congenital malformation of the inner ear, these techniques should be considered complementary. Since prompt intervention has a positive impact on the treatment outcomes, early diagnosis of IEMs is very important in the management of deaf patients. This article reviews the key concepts of IEMs for clinical radiologists by focusing on recent literature updates, discusses the principal imaging findings and clinical implications for every IEM subgroup, thus providing a practical diagnostic approach.

“…5 In cases with severe or profound hearing loss (HL), quite a high prevalence of inner ear malformations (IEMs) of around 15 to 20% has been reported in a study. 6 Though cochlear implantation in cases with IEMs has favorable surgical and speech results 7 and is a safe procedure in experienced hands, 8 however difficulties and intraoperative complications do occur. 9 Complications ranging from pain, minor bleed, infection, breakdown of skin, facial palsy, taste changes, vertigo, cerebrospinal fluid leak, device failure as well as mal-placement, skull base and brain damage to complete deafness and death may occur.…”

Objectives: To determine the prevalence of complications of cochlear implant surgery in children with congenital profound sensorineural hearing loss. Methods: This study retrospectively & consecutively reviewed charts of children who underwent cochlear implantation from July 2015 to July 2019 at Cochlear Implant Centre of Otolaryngology Department of Capital Hospital, Islamabad Pakistan. These included cases of both genders aged one to 12 years operated at least one year before the time of data collection. Basic demographic data, complications including major and minor complications and treatment received was noted and statistically analyzed using SPSS-23. Results were presented using descriptive statistics. Results: Current study included a sample of N=251 having a mean age of 4.05±2.15 years including 154(61.4%) males and 97(38.6%) females revealed a prevalence of complications of 16(6.4%) with 4(1.6%) major and 12(4.8%) minor complications. Wound infection and acute otitis media with frequency of 3(1.2%) each were the commonest complications, followed by , facial nerve twitching, tinnitus and vertigo, infection and extrusion; and device failure in 2(0.8%) each. However, there was no significant association of complications with age group and gender with P=0.344 and P=0.519 respectively. Conclusion: Present public sector implant program is characterized with a very low prevalence of complications of 16(6.4%) with 4(1.6%) major and 12(4.8%) minor complications. Wound infection and acute otitis media were the commonest complications. doi: https://doi.org/10.12669/pjms.37.5.3960 How to cite this:Ahmed J, Saqulain G, Khan MIJ, Kausar M.
