[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. Its application allowed the results of the treatment to be optimized as confirmed by the statistically significant improvement of the external respiration function, acoustic characteristics of the voice, and positive dynamics of laryngeal endoscopic imaging data.
