Three patients with early-stage laryngeal cancer (glottic, T1N0M0) were treated by the surgery of Conley's glottis reconstruction. Abilities of swallowing and phonation after the surgery were found to be satisfactory. The surgical procedure was improved in the following two points: 1. The vocal cord was made by a skin ridge instead of a skin roll to facilitate voice production. 2. An opening was made in the thyroid cartilage to avoid excessive pressure on the base of the skin flap. The case indicated for this surgery has the indication of irradiation, too. This surgical procedure, however, seems to be more suited for the treatment of early cancer of the glottis in which preservation of acceptable voice is intended.
