Conducted at KLES Dr. Prabhakar Kore Hospital, Belagavi, this study utilized 25 wet cadaveric temporal bones obtained from fresh cadavers at J. N. Medical College. Dissections were performed to study the facial nerve's course and its variations, along with morphometric comparisons to other intratemporal structures. The greatest variation was found in the depth of the second genu, measured by adding the short process of incus to the spine of Henle and short process of incus to the second genu, ranging from 12.6 mm to 19.2 mm. The lengths of the mastoid (9.80 mm) and tympanic segments (5.71 mm) were relatively consistent. The processus cochleariformis was a reliable landmark for the tympanic segment. Isolated facial nerve anomalies are rare and typically occur with other middle ear developmental anomalies. Minute morphometric variations, however, can lead to iatrogenic injuries. While advanced imaging aids in identifying these variations, temporal bone dissection remains crucial for otologists to avoid injuries and address nerve pathologies effectively.</p>","PeriodicalId":49190,"journal":{"name":"Indian Journal of Otolaryngology and Head and Neck Surgery","volume":"77 7","pages":"2556-2561"},"PeriodicalIF":0.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144276422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although hands-on training under faculty supervision is common, it carries risks such as patient discomfort and complications. Skill lab training mitigates these risks, but skill decay over time remains a concern. This study evaluates skill retention in fiberoptic laryngoscopy over a two-month period without practice and the necessity of retraining. A prospective study was conducted at Maulana Azad Medical College with 24 ENT residents. After ethical approval, participants underwent a standardized didactic session and hands-on mannequin-based training. Proficiency was assessed using an objective checklist. After two months without practice, skill retention was reassessed without retraining. A paired t-test and effect size analysis were used for statistical evaluation. The mean proficiency score declined from 15.70 (SD ± 2.95) to 13.70 (SD ± 2.80) (<i>p</i> < 0.001), demonstrating significant skill decay. A strong effect size (Cohen's d = 1.08) highlighted the clinical relevance of this decline. While some residents maintained proficiency, others showed substantial deterioration, with five residents losing 4-6 points. A strong positive correlation (<i>r</i> = 0.79) between initial and follow-up scores suggested that higher initial proficiency predicted better retention. Fiberoptic laryngoscopy skills decline significantly over two months, underscoring the need for periodic refresher training. Personalized retraining, simulation-based learning, and structured continuing education could help mitigate skill loss and enhance long-term competency.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s12070-025-05494-5.</p>","PeriodicalId":49190,"journal":{"name":"Indian Journal of Otolaryngology and Head and Neck Surgery","volume":"77 7","pages":"2449-2453"},"PeriodicalIF":0.6,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144276412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
