Rigid videolaryngoscope for difficult intubation caused by mandibular tori

摘要

A mandibular torus, an exophytic bony protuberance located along the lingual aspect of the mandible, often increases in size with aging and occupies the floor of the mouth. The torus is one of the most common oral exosto-ses, with its occurrence reported in up to 63.4% of the population. However, it requires no treatment unless it interferes with denture fabrication or leads to recurrent traumatic surface ulceration [1]. Massive mandibular tori cause severe difficult tracheal intubation, which can require emergent cricothyrotomy [2]. A previous report recommends tracheal intubation using the flexible fiberoptic bronchoscope in such patients [3], although flexible fiberoptic bronchoscopic intubation requires an experienced user. Recently, various rigid videolaryngoscopes have been developed as alternative devices to improve glottic view and may require less operator skill [4].
