Objective: This paper provides a detailed description of the Nucleus 6 system, and clinically evaluates user performance compared to the previous Nucleus 5 system in cochlear implant recipients. Additionally, it clinically evaluates a range of Nucleus 6 and Nucleus 5 programs to determine the performance benefits provided by new input processing technologies available in SmartSound iQ.
Design: Speech understanding tests were used to clinically validate the default Nucleus 6 program, by comparing performance outcomes against up to five custom Nucleus 5 or Nucleus 6 programs in a range of listening environments. Clinical comparisons between programs were conducted across the following listening environments; quiet, speech weighted noise (co-located and spatially separated noise), and 4-talker babble (co-located and spatially separated noise).
Study Sample: Twenty-one adult cochlear implant recipients participated.
Results: Significant speech understanding benefits were found with the default Nucleus 6 program compared to the participants' preferred program using their Nucleus 5 processor and compared to a range of custom Nucleus 6 programs. All participants successfully accepted and upgraded to the new default Nucleus 6 SmartSound iQ program.
Conclusion: This study demonstrates the acceptance and clinical benefits of the Nucleus 6 cochlear implant system and SmartSound iQ.

Cochlear implantation (CI) is currently recognized as the most effective treatment for severe to profound sensorineural deafness and is considered one of the most successful neural prostheses. Since its inception in 1961, cochlear implantation has expanded its range of applications to encompass younger newborns, older people, and individuals with unilateral hearing loss. In addition, it has improved its surgical methods to minimize the occurrence of complications.

Purpose: To analyze the effect of right versus left long-term single-sided deafness (SSD) on sound source localization (SSL), discuss the necessity of intervention and treatment for SSD patients, and analyze the therapeutic effect of long-term unilateral cochlear implantation (UCI) from the perspective of SSL.
Methods: This study included 25 patients with SSD, 11 patients with UCI, and 30 participants with normal hearing (NH). Their SSL ability was tested by obtaining their average root mean square (RMS) error values of SSL test.
Objectives: The movement towards personalization of cochlear implantation has continued to generate interest about variabilities in cochlear size. In a recent meta-analysis, Atalay et al. (2022) examined organ of corti length, cochlear lateral wall, and "A" value and found that most covariates, other than congenital sensorineural hearing loss, did not impact cochlear size via these measurements.

Thiamine responsive megaloblastic anemia (TRMA), also known as Roger's syndrome, is an exceptionally rare autosomal recessive disorder stemming from mutations in the SLC19A2 gene responsible for encoding a thiamine carrier protein. This syndrome manifests as the classic triad of megaloblastic anemia, sensorineural hearing loss, and diabetes mellitus. Here, we present the case of a one-and-a-half-year-old male infant born to non-consanguineous parents in India, a region where TRMA cases are seldom reported.

Background: There still exists controversy about whether the healthy human middle ear mucosa is sterile or if it may harbor a diverse microbiome. Considering the delicacy of the human round window membrane (RWM), different mechanisms may exist for avoiding inner ear pathogen invasion causing sensorineural deafness. We re-analyzed archival human RWMs using light and transmission electron microscopy after decalcification to determine if bacteria are present in clinically normal human middle ears.
