Objectives: Congenital hearing loss is a significant health concern, with diverse etiologies encompassing cochlear and cochleovestibular pathologies. Preoperative radiological evaluation in cochlear implant candidates is pivotal for treatment planning. We aim to elucidate the spectrum of radiological findings in patients with congenital hearing loss undergoing cochlear implant assessment. Methods: An analysis included 389 sensorineural hearing loss (SNHL) patients who underwent cochlear implantation at a tertiary university hospital, of which 177 were congenital SNHL. Computed tomography (CT) and magnetic resonance imaging (MRI) data were meticulously assessed for diverse congenital pathologies, focusing on congenital malformations. Results: In the congenital SNHL group, comprising 177 patients (80 females and 97 males), congenital cochleovestibular malformations were evident in 56 ears of 29 cases. Different congenital cochleovestibular malformations, ranging from labyrinthine aplasia to isolated large vestibular aqueducts, were detected. Among the various anomalies, incomplete partitions and cochlear hypoplasia emerged as more frequent patterns. Conclusions: This study offers a comprehensive radiological analysis of congenital SNHL patients undergoing cochlear implantation, revealing a spectrum of anomalies. It demonstrates the diverse nature of anomalies affecting the external auditory canal, middle ear structures, and cochleovestibular system. These insights provide a deeper understanding of congenital SNHL and contribute to developing informed treatment strategies.

Greater trochanteric pain syndrome (GTPS) is a common cause of hip pain and is often associated with chronic lower back pain and lower extremity osteoarthritis. Its diagnosis is clinical; however, imaging has been shown to aid in the differential diagnosis of challenging cases. Superb microvascular imaging (SMI) is a new technique that may be more effective than power Doppler ultrasonography (PDUS) in the detection of inflammation-related vascularity in patients. In this study, we aimed to compare the diagnostic accuracies of SMI and PDUS in patients with GTPS and evaluate the usefulness of these techniques in clinical practice. We recruited 37 GTPS patients and 15 healthy volunteers for participation in this study. PDUS and SMI examinations were performed and we retrospectively reviewed the magnetic resonance imaging scans for tendinosis, tears, and edema. The PDUS and SMI were positive in 19 and 31 hips, respectively. Both techniques had low sensitivity but high specificity and positive predictive values, with SMI being slightly better. PDUS and SMI had accuracies of 75% and 82.7%, respectively, with a grade 1 vascularization threshold. Moreover, magnetic resonance imaging detected peritendinous edema with an accuracy of 60.5%, including tendinosis and partial tears but not complete tendon tears. Our study showed that PDUS is an underutilized modality in the diagnosis of GTPS and that SMI may further improve diagnostic accuracy. However, the low sensitivity of both techniques suggests that a clinical diagnosis remains essential.
