title: Combined therapy with isoprinosine and CO2 laser microsurgery for the treatment of laryngeal papillomatosis.
abstract: Recurrent laryngeal papillomas and their potential malignant degenerations in adult patients have been known clinically for about 100 years. An early effective treatment has great importance in preventing possible obstruction of the airway or malignant change. The use of endoscopic microsurgery with the CO2 laser has resulted in a significant improvement in the eradication of papillomatous nodules. The advantages of laser surgery are: better visualization of the larynx to allow more precise and deeper resection of papillomas, limited bleeding, and a reduced possibility of seeding uninvolved mucosa. Although laser surgery is the current method of choice for treating laryngeal papillomatosis, it has not solved completely the problems of recurrences. To make treatment more effective, we have developed a therapeutic regimen that combines laser microsurgery with the immunostimulant methisoprinol (Isoprinosine). Our observations in 18 patients have shown that this combined management was more successful than using a single modility with either the laser or Isoprinosine alone. The combined approach was also effective in recurrent cases, with the timing of the combination influencing the results of the treatment given.
