Abstract
Our aim was to report our experience with office-based treatment of severe laryngeal papillomatosis with percutaneous injection of cidofovir in a case series of 5 patients. We conducted a retrospective review of a case series in a tertiary academic care voice disorders clinic. Adult patients with papillomas of the vocal cords and anterior commissure received percutaneous injection using a point-touch technique. Clinical improvement or remission of the papillomatosis was noted. Before initiation of office treatments, patients required direct laryngoscopy and CO2 laser ablation of papillomas on average every 2.8 months. There were no complications related to the injection technique. During a treatment period of 7 to 16 months (mean 12 months), a significant reduction in the volume of papillomatosis was achieved in all patients. One patient received 2 treatments and another received 1 treatment in the operating room for final clearance of papillomas. Office-based treatment of adult patients with anterior laryngeal papillomatosis using percutaneous injection of cidofovir reduces the need for repeated direct laryngoscopy and laser ablation under general anesthesia. Percutaneous injection treatment with cidofovir is a useful adjunct to direct laryngoscopy and laser ablation in the treatment of laryngeal papillomatosis.
