Background: Cochlear implants (CI) help regain perception of sound for patients with sensorineural hearing loss. The ability to recognize music pitch may be crucial for recognizing and producing speech for Mandarin.

Aims/objectives: This study aims to search for possible influencing factors of music perception and correlations between music perception and auditory speech abilities among prelingually deaf pediatric Mandarin-speaking CI users.

Article Synopsis
  • MYO15A gene mutations are linked to severe sensorineural deafness, impacting those both before and after they acquire language, with a novel mutation (c.2482C>T) found in a Chinese Uighur family identified in this study.* -
  • Researchers created induced pluripotent stem cells (iPSCs) from family members to explore how the MYO15A mutation affects hair cell-like cells, which are important for hearing.* -
  • The findings revealed that the mutation caused noticeable differences in the structure and function of these cells, indicating a possible link to hearing loss, while not affecting the iPSCs' ability to become different cell types.*

Article Synopsis
  • - Usher syndrome type 3 (USH3) is an inherited disorder linked to mutations in the CLRN1 gene, leading to hearing and vision impairments.
  • - A study analyzed a three-generation deaf-blind Chinese family to establish how specific genetic variants correlated with the disease symptoms, identifying significant differences in mutations across various gene transcripts.
  • - The unique mutation CLRN1:c.474T > A, discovered in this family, is confirmed as the cause of USH3 and highlights the necessity of considering different genetic transcripts in mutation analysis.

Retiform hemangioendothelioma (RH) is a rare intermediate (locally aggressive) vascular tumor that mostly affects the dermis of the trunk and limbs, but has never been reported in the inferior turbinate. A 10-year-old Chinese boy presented with recurrent epistaxis in his left nasal cavity and anemia for more than 2 years. Radiographic and electronic video laryngoscopic images showed an expansile mass in the left inferior turbinate.

Defects in mitochondrial RNA metabolism have been linked to sensorineural deafness that often occurs as a consequence of damaged or deficient inner ear hair cells. In this report, we investigated the molecular mechanism underlying a deafness-associated tRNA 593T > C mutation that changed a highly conserved uracil to cytosine at position 17 of the DHU-loop. The m.

To investigate the consistency between the hearing handicap inventory (HHI) and pure-tone audiometry (PTA) scores in assessing hearing status to provide valuable insights for clinical application. Retrospective analysis of clinical data and the HHI reporting status of 6540 patients admitted between April 2020 and July 2022 for self-reported unilateral hearing loss who met the study inclusion and exclusion criteria. The kappa coefficient was used to evaluate the consistency of HHI and PTA in assessing the hearing status of the participants.

Objectives: To evaluate the mental health of paediatric cochlear implant users and analyse the relationship between six dimensions (movements, cognitive ability, emotion and will, sociality, living habits and language) and hearing and speech rehabilitation.

Methods: Eighty-two cochlear implant users were assessed using the Mental Health Survey Questionnaire. Age at implantation, time of implant use and listening modes were investigated.

Implantable bonebridge(BB) is suitable for patients over 5 years with conductive/mixed hearing loss and unilateral deafness, and the surgical approach depends on the anatomical structure of the patient's ear. Recent studies have shown that compared with other implantable hearing devices, implantable BB have more efficient hearing gain and lower incidence of complications. However, the postoperative effect of implantable BB on unilateral deafness patients and the poor compensation of low-frequency hearing threshold need to be further studied.

This paper reported a case of superficial angiomyxoma in the region of the nasal vestibule. The clinical manifestation was swelling of the left nasal vestibular skin, while paranasal sinus CT showed swell soft tissue in the anterior and superior region to the left maxilla. Under general anesthesia, the left nasal vestibular mass was resected under nasal endoscopy.

Objective: To expose the spectrum and frequency of GJB2, GJB3, SLC26A4 and MT-RNR1 in northwest China and to investigate the underlying causative genes in patients without common mutations.

Methods: We analyzed the mutation screening results of GJB2, GJB3, SLC26A4 and MT-RNR1 in 398 unrelated severe-to-profound probands with bilateral, symmetrical sensorineural hearing loss. Subsequently, we selected 10 probands with a significant family history of inherited hearing loss (HL) that did not have the above four common gene mutations to perform next-generation sequencing (NGS) of 139 known deafness genes, followed by co-segregation analysis of all available family members.
