An innovative ‘Prop technique’ of mouth opening in post-COVID-19 mucormycosis maxillectomy: Finding a new way with minimal efforts

General anaesthesia is associated with damage to teeth, particularly during laryngoscopy. Dental injury is more probable when pre-existing dental pathology or risk factors are present. Post-coronavirus disease -2019 mucormycosis is a rare, fulminant, lethal, angio-invasive, opportunistic fungal disease and is increasingly recognised in diabetic and immunocompromised patients. Since the flange of the laryngoscope blade appears to be the source of tooth injury, alternate methods of wide mouth opening during laryngoscopy should be examined, especially when mouth opening is limited. In this case series, we have studied 12 cases of maxillectomies with an aim to improve restricted mouth opening by using the 'Prop technique' resulting in a minimum hinging force of the flange of the blade on teeth. Preoperatively, patients were warned about the possibility of dental injuries during anaesthesia or surgery.
