Laser surgery with Curved Laryngo-pharyngoscope for early glottic carcinoma

As a treatment for early-stage glottic cancer, we have performed laser surgery with Satouʼs curved laryngo-pharyngo scope, a flexible endoscope for otolaryngology, and a fiber-delivered laser. The advantages of this surgery are: 1） We can observe in detail the laryngeal ventricle and the subglottis by using the ﬂexible endoscope and the narrow band imaging system （NBI）, and 2） This surgery can also be performed for patients with poor condition of cervical vertebrae and teeth, in whom conventional microscope surgery cannot be performed. This surgery has local a control rate and laryngeal preservation rate comparable to those by conventional treatments.
