Juvenile papillomatosis is the most common benign laryngeal tumor in children, caused by HPV types 6 and 11. It is thought children contract it from their mothers during birth if the mother had HPV. Papillomas typically affect the supraglottic and glottic regions but can spread lower. Children who had tracheostomies are more likely to have tracheal and stoma involvement due to seeding. Symptoms include hoarseness, difficulty breathing, or stridor in children ages 3-5. Diagnosis is via laryngoscopy and biopsy. Treatment involves laser excision to remove papillomas while preserving the voice, but recurrence is common and requires repeated procedures.
