[Usefulness of ND:YAG laser in head and neck surgery]

Nd:YAG laser is widely used in surgery as well as in otolaryngology and head and neck surgery for 25 years. This type of laser is characterized by low absorption in water and haemoglobin, deep penetration to the tissue and high ability for vessels coagulation. The laser light can be guided with glassfiber and can be focussed with handpices and micromanipulators. These characteristics make Nd:YAG laser very useful surgical instrument, especially in ORL and head and neck surgery. One institution's experiences, based on 300 operations with Nd:YAG laser are presented and discussed. Main indications to Nd:YAG laser operations in our material were: malignant neoplasms of oral cavity, pharynx and larynx, papillomas and haemangiomas of mucosa of upper respiratory tract, tracheal stenoses, scars of the larynx after partial laryngectomies and snoring and sleep apnoea syndrome. In our opinion, Nd:YAG laser has high usefulness in treatment of malignant and benign head and neck neoplasms, as well as in laryngeal scars and treatment of snoring. In cases of post intubation tracheal stenoses and in cases of post strumectomy bilateral paralysis of larynx the treatment results were not satisfactory. High usefulness of Nd:YAG laser results from very good coagulation ability and wide possibility of transmission of laser light with glassfiber.
