Juvenile papilloma :
Occurs in infants and young children. It is multiple, and show aggressive behaviour. These lesions are known to recur even after successful surgery.

Tracheostomy: to secure the airway if the patient manifests with stridor.
Microlaryngeal excision of the masses - Bleeding and airway complications are common during this procedure.
Cryosurgery - Bleeding is minimised during this procedure
Laser surgery - Is best suited for juvenile papillomas. In this procedure the bleeding is minimal, and scarring is also minimal.
Recurrence - In juvenile papilloma can be reduced by postoperative treatment with interferon. Herbal drung (TUJA) has been tried with varying degrees of success.
