Objective:To describe a novel approach for intractable Meniere's disease exclusively through a transcanal endoscopic ear surgery（TEES）. Methods:This retrospective chart review included patients with intractable Menière's disease who underwent endoscopic transcanal labyrinthectomy in the Department of Otolaryngology Head and Neck Surgery, Guangxi Hospital Division, First Affiliated Hospital, Sun Yat-sen University, between February 2023 and October 2024. The first 70-year-old woman and the other 67-year-old woman, who underwent multiple conservative treatment and chemical labyrinthectomy during outpatient and hospitalization, had frequent vertigo, tinnitus and severe sensorineural deafness. The TEES approach provided a wide exposure of the oval window. The incus and the stapes were removed, expanded the oval window. The perilymph was suctioned, The saccule, utricule, macula utriculi and macula sacculi were removed. The ampulla tissue of the three semicircular canal were destroyed with the right-angle crochet. The oval window was obliterated using the perichondrium of the tragal cartilage and cartilage. Results:Two patients underwent endoscopic transcanal labyrinthectomy, and no intraoperative or postoperative complications were observed. Vertigo was controlled in 2 patients during the follow-up of 6 to 12 months. Two patients complained of total hearing loss after surgery. Conclusion:Even though this study presents a limited number of cases, endoscopic transcanal labyrinthectomy is a promising, safe, and effective procedure in selected cases. Additional studies are needed to determine the risk-benefit profile of this technique.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with non-syndromic hearing loss (NSHL). METHODS: Commercialized gene chip was applied to detect common mutations associated with congenital deafness. Whole exome sequencing was carried out for patients for whom gene chip yielded a negative result. Candidate variants were verified by Sanger sequencing. RESULTS: Two patients from the pedigree were discovered to carry compound heterozygous variants of the TRIOBP gene, namely c.3299C>A and c.5185-2A>G. Their parents had normal hearing and were both heterozygous carriers of the above variants. Both variants had co-segregated with the disease phenotype in the pedigree and were unreported previously. CONCLUSION Pathogenic variants of the TRIOBP gene comprise an important factor for NSHL. The novel c.5185-2A>G and c.3299C>A variants discovered in this study have enriched the mutational spectrum of the TRIOBP gene and enabled molecular diagnosis and genetic counseling for the family.

Objective To study the features and reasons of violent events in medical staff and the public sentiments on them based on a network analysis. Methods The data of violent events in medical staff were down-loaded from Internet. The annual and geographic distribution and reasons of violent events in medical staff, casualties of medi-cal staff and the public opinions on the major Websites were analyzed. Results The number of violent events in medical staff increased to 31 in 2012 from 1 in 2003. The violent events were distributed in 18 provinces of China, the number of casualties was 105 , and 53% of the violent events occurred due to the unsatisfactory therapeutic out-comes in patients. Conclusion The public sentiments on violent events in medical staff tend to increase on Internet and characterized by no signs and direct conflict between patients or their family members before attacking medical staff, and against general medical staff. Public sentiments on violent events in medical staff are easy to become hot events with significant negative effects on the society. Medical institutions and hospitals should prevent such events and play an active role in guiding the public sentiments.
