Preservation of function and Complete excision of the cancer are the prime consideration in all aspects of head and neck surgery. Conservation surgery of the larynx means to remove primary malignant lesion, but preserves natural respiration, deglutition, and phonation of the larynx. It can be accomplished in the larynx by combining information on tumor behavior with knowledge of the unique compartments and barriers of the larynx. According to the location of the lesion and areas of extension, various techniques of the partial laryngectomy have been developed since H.B. Sands performed the first partial laryngectomy for glottic cancer in 1863. Ogura and Biller estimated that 50% of all laryngeal and laryngopharyngeal cancer were amenable to conservation surgery. We have experienced 7 cases of conservation surgery in laryngeal cancer from 1984 to 1987, which were 4 cases of frontolarteral hemilaryngectomy, 1 case of anterior frontal vertical laryngectomy(Anterior commissure technique), 1 case of Three-quarter laryngectomy, and 1 case of supraglottic partial laryngopharyngectomy. So we report these results with review of the literature.
