- Abstract: Objective To study the clinical application value of the upright seated + head down(30° to 45°)+ tongue protrusion technique for the completely exposure of the epiglottic surface under electronic laryngoscopy.Methods Based on the clinical examination process of electronic laryngoscopy in the laryngoscopy room,two methods were applied for the patients with difficulty in exposing the epiglottic surface:① upright seated + tongue protrusion;② upright seated + head down(30° to 45°)+ tongue protrusion.The proportions of patients exposed to the epiglottic surface by these two methods were compared.Results The electronic laryngoscopy examination used the upright seated + tongue protrusion technique allowed for the clear exposure of the epiglottic surface in approximately 73.91%of patients with exposure difficulty.By using the upright seated + head down(30° to 45°)+ tongue protrusion technique,combined with the operator's control over the free movement of the laryngoscope's front end lens into the epiglottic vallecula space for close-range exploration,a 100%clear exploration of the epiglottic surface was achieved.Conclusion The upright seated + head down(30° to 45°)+ tongue protrusion technique for electronic laryngoscopy examination in patients with difficulty in exposing the epiglottic surface can completely expose the epiglottic surface,with significantly clinical effect.It can be used as a supplementary examination method for patients with difficulty in exposing the epiglottic surface in the ordinary upright seated or upright seated + tongue protrusion technique,and has certain clinical application value.
