Background And Aims: Bedside screening test for predicting difficult intubation is an accepted practice, even though its clinical value remains limited. This study aimed to study the predicting value of acromioaxillosuprasternal notch index (AASI) for difficult visualisation of the larynx (DVL).
Methods: After Hospital Ethical Committee approval, 440 consecutive consenting adult non-obstetric patients were included in this study. AASI, modified Mallampati class (MMT), sternomental distance (SMD), thyromental distance (TMD) and inter incisor distance (IID) were evaluated preoperatively by trained personnel. Visualisation of larynx was graded according to Cormack-Lehane grading, with grade III and IV being considered as DVL. The cut-off values for prediction of DVL were defined a . Direct laryngoscopy was carried out by qualified anaesthesiologists blinded to the results of the airway predictors under evaluation. Primary outcome variable was AASI as a predictor of DVL. Comparing DVL with MMT, SMD, TMD and IID were secondary objectives.
Results: DVL was observed in 3.6% [95% confidence interval (1.9-5.4%)] patients. We observed that sensitivity, specificity and Area Under Curve i.e., AUC (95% confidence interval) of ROC of AASI was 81.25 (53.69-95.03), 96.7 (94.39-98.11) and 0.890 (0.777-1.000) respectively. AUC of AASI was found to better than MMT, SMD, TMD and IID.
Conclusion: AASI (≥0.5) is a good predictor of difficult visualisation of the larynx at direct laryngoscopy.

Objective: To develop a reproducible survival rabbit model for laryngotracheal stenosis (LTS).
Methods: Seventy New Zealand white (NZW) rabbits were randomly divided into experimental groups ( = 30) and a control group ( = 40). In experimental groups, a nylon brush was inserted retrograde from the tracheotomy through the subglottis and rotated until a full layer circumferential mucosal injury to cartilage exposure, assisted by fiberoptic laryngoscopy (FOL) visualization.

To explore and summarize the morphological features of laryngeal tuberculosis under electronic laryngoscopy and image-enhanced endoscopy (i-scan). A retrospective analysis was conducted on the data of 31 patients diagnosed with laryngeal tuberculosis at the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2014 to June 2024, encompassing the morphological features of electronic laryngoscopy and i-scan endoscopy, histopathological features, and supplementary clinical examination results. Descriptive statistical methods were employed for the analysis.

The diagnosis and staging of head and neck tumors requires proper clinical, endoscopic, and radiological evaluation. Currently, imaging techniques such as Magnetic Resonance Imagining (MRI) and Computed Tomography (CT) are used for head and neck tumors but are limited in showing involvement of different hypopharyngeal sub-compartments. Several maneuvers have been developed to improve visualization of the head and neck area; however, they demonstrated minimal benefit.

On 23 April 1895, the Berlin ENT medical specialist Alfred Kirstein performed the first direct examination of the larynx using a Casper esophagoscope equipped with electric lighting, which he called an "autoscope". The examination of the larynx, which had previously only been possible indirectly using mirror systems, was named by him "autoscopy". The development of the device enabled a more precise observation than before and laryngeal or tracheal foreign bodies could be removed better and more easily.

Background: Age-related vocal atrophy (ARVA) causes vocal fold bowing, impacting communication and quality of life. The assessment of vocal fold bowing is largely subjective. Glottal Image Capture (GlottIC) is a new mobile application that helps quantify vocal fold bowing.
