[Endolaryngeal laser-assisted microsurgery of benign pharyngeal neoplasms: objective evaluation of functional outcome].

A new technique for endolaryngeal microsurgery is proposed. It based on the irradiation of benign laryngeal tumours using Ho:YAG and potassium-titanyl-phosphate (KTP) lasers. A total of 198 patients of either sex aged from 2 to 77 years with a variety of benign laryngeal neoplasms were treated by this method between 2004 and 2007.
