Abstract Conservation laryngeal surgery refers to techniques that preserve the sphincteric, respiratory, and phonatory functions of the larynx. The techniques vary from simple excisions of small laryngeal cancers to technically difficult resections of the supraglottic region and hypopharynx and reconstruction of the remaining laryngeal structures. All of these conservative laryngeal techniques are based on the knowledge of the exact extent of the tumor and its pathophysiologic course in terms of local tumor spread and metastatic pathways. Conservation laryngeal surgery includes two main categories, vertical partial laryngectomies, which varies from simple cordectomy to more sophisticated surgical techniques as hemilaryngectomy, anterior frontal laryngectomy and frontolateral laryngectomy. The other category is hO,rizontal partial laryngectomy, which includes supraglottic laryngectomy and supracricoid .laryngectomy, In the last decade of the 20th century, endoscopic or transoral partial laryngectomies, using C02 laser, have been introduced. |
