[The treatment of juvenile laryngeal papillomatosis with argon plasma coagulation].
METHODS
At 3 years of age a girl known for one year to have progressive juvenile laryngeal papillomatosis with involvement of the lower respiratory tract was seen by her general practitioner because of increasing hoarseness. As about 20 sessions of CO2-laser treatment and adjuvant administration of interferon-alpha had failed to prevent increasing glottal stenosis and spread of the tracheal involvement, a tracheostomy had to be performed. Removal of the papilloma became progressively more difficult and at the age of 6 years she was admitted for further treatment.


METHODS
She had marked inspiratory and expiratory stridor. Results of laboratory tests were unremarkable. Examination of the respiratory tract with a flexible endoscope revealed obstruction of the tracheal lumen by the papilloma.


METHODS
The papilloma was removed by argon plasma coagulation (APC) under general anaesthesia during intermittent apnoeic phases. After four treatment sessions no papilloma could be seen endoscopically. There were no side effects or complications. The interval between treatments has become progressively longer. Further removal of papilloma is only rarely necessary nowadays.


CONCLUSIONS
APC via a flexible endoscope is a promising method in the treatment of juvenile laryngeal papillomatosis involving the lower respiratory tract. It achieves precise, circumscribed tissue penetration without carbonisation or steaming-up, while bleeding can be controlled.
