RESUMEN
Objective:To investigate the characteristics and prognosis of two anastomosis techniques in repairing facial nerve defects. Methods:A retrospective analysis was conducted on 30 patients who underwent facial nerve anastomosisï¼direct or reroutingï¼ for facial nerve defects in our department from January 2012 to December 2021. Among them, 21 were male and 9 were female, with an average age ofï¼37.53±11.33ï¼ years, all with unilateral onset. Preoperative House-Brackmannï¼H-Bï¼ facial nerve function grades were â £ in 2 cases, â ¤ in 9 cases, and â ¥in 19 cases. The duration of facial paralysis before surgery was within 6 months in 21 cases, 6-12 months in 6 cases, and over 1 year in 3 cases. The causes of facial paralysis included 14 cases of cholesteatoma, 6 cases of facial neurioma, 6 cases of trauma, and 4 cases of middle ear surgery injury. Surgical approaches included 9 cases of the middle cranial fossa approach, 8 cases of labyrinthine-otic approach, 7 cases of mastoid-epitympanum approach, and 6 cases of retroauricular lateral neck approach. Results:All patients were followed up for more than 2 years. The direct anastomosis was performed in 10 cases: 6 cases with defects located in the extratemporal segment and 4 cases in the tympanic segment. Rerouting anastomosis was performed in 20 cases: 11 cases with defects located in the labyrinthine-geniculate ganglion, 4 cases from the internal auditory canal to the geniculate ganglion, 3 cases in the internal auditory canal, and 2 cases in the horizontal-pyramid segment. Postoperative H-B facial nerve grades were â ¡ in 2 cases, â ¢ in 20 cases, and â £ in 8 cases, with 73.3%ï¼22/30ï¼ of patients achieving H-B grade â ¢ or better. Conclusion:Both direct and rerouting anastomosis techniques can effectively repair facial nerve defects, with no significant difference in efficacy between the two techniques. Most patients can achieve H-B grade â ¢ or better facial nerve function recovery. Preoperative facial nerve function and duration of facial paralysis are the main prognostic factors affecting the outcome of facial nerve anastomosis.

PURPOSE: So far, there have been no in-depth analyses of the connection between tinnitus sensation-level loudness and sleep quality. Accordingly, the present study was formulated as a mediation analysis focused on exploring this relationship. METHOD: Overall, 1,255 adults with consecutive subjective tinnitus who had sought outpatient treatment were enrolled in the present study. RESULTS: Direct effects of tinnitus sensation-level loudness on sleep quality were not statistically significant (95% confidence intervals [CI] include zero), as measured by the point estimate, -0.016. However, the 95% CI for indirect effects did not include zero when assessing the Self-Rating Anxiety Scale (SAS) scores, the Self-Rating Depression Scale (SDS) scores, the visual analogue scale (VAS) scores, and self-reported tinnitus annoyance. CONCLUSIONS: These results suggest that tinnitus sensation-level loudness does not directly have an effect on sleep quality. However, it indirectly impacts sleep quality, mediated by SAS scores, SDS scores, the impact of tinnitus on life measured using the VAS, and self-reported tinnitus annoyance. As such, alleviating anxiety and depression in patients with tinnitus may result in reductions in their insomnia even if there is no reduction in tinnitus loudness. Importantly, otolaryngologists and other clinicians treating tinnitus should refer patients with tinnitus suffering from insomnia with comorbid depression or anxiety for appropriate psychological and/or psychiatric treatment.

BACKGROUND: Mutations in MPZL2, the characteristic genetic etiology of autosomal recessive deafness loci 111 (DFNB111), cause non-syndromic and moderate sensorineural hearing loss. METHODS: In this study, we analyzed the phenotype and genotype of eight pedigrees consisting of 10 hearing loss patients with bi-allelic pathogenic or likely pathogenic variants in MPZL2. These patients were identified from a 3272 Chinese patient cohort who underwent genetic testing. RESULTS: Apart from symmetrical and moderate sensorineural hearing loss, the MPZL2-related phenotype was characterized by progressive hearing loss with variation in the onset age (congenital defect to onset at the young adult stage). We determined that in the Chinese population, the genetic load of MPZL2 defects was 0.24% (8/3272) in patients diagnosed with hearing loss and 7.02% (8/114) in patients diagnosed with hereditary moderate sensorineural hearing loss caused by STRC, OTOA, OTOG, OTOGL, TECTA, MPZL2 and others. Three known MPZL2 variants (c.220C > T (p.Gln74*), c.68delC (p.Pro23Leufs*2), c.463delG (p.Ala155Leufs*10)) and a novel start loss variant (c.3G > T (p.Met1?)) were identified. MPZL2 c.220C > T was identified as the hotspot variant in the Chinese population and even in East Asia compared with c.72delA (p.Ile24Metfs*22) in European and West Asia through allele frequency. CONCLUSIONS: We concluded that apart from moderate HL, progressive HL is another character of MPZL2-related HL. No specified variant was verified for the progression of HL, the penetrance and expressivity cannot be determined yet. A novel MPZL2 variant at the start codon was identified, enriching the variant spectrum of MPZL2. The hotspot variants of MPZL2 vary in different ethnicities. This study provides valuable data for the diagnosis, prognosis evaluation and genetic counseling of patients with moderate sensorineural hearing loss related to MPZL2.
