[The usage of allograft nasal septal cartilage in partial laryngectomy]

Based on the experiment of five dogs, 22 cases of laryngeal carcinoma using allograft nasal septal cartilage as a framework for laryngeal defect after partial larygectomy are reported. After 5 years follow-up, the functions of phonation and respiration of 17 cases were satisfying and their phonatic loudness was raised remarkably. The method was used mainly for patients with T1 glottic carcinoma involving anterion commissure and selective T2, T3 glottic carcinoma. The advantages of allograft nasal septal cartilage in partial laryngectomy are discussed in comparison with auto nasal mucoseptal graft.
