This case report describes the use of CO2 laser and quadrivalent human papillomavirus (HPV) vaccination in two patients with nasopharyngeal HPV11-positive recurrent respiratory papillomas (RRP). These patients initially underwent CO2 laser excision but developed recurrent lesions and underwent HPV vaccination as adjunct therapy. The recurrent lesions shrank after vaccination and were again excised with CO2 laser. Subsequently, these patients had no recurrence of lesions on long-term follow-up at 33 months or 6 years after surgery. Thus, in patients with nasopharyngeal RRP, resection with CO2 laser, and HPV vaccination as adjunct therapy should be considered in HPV11-associated cases. Laryngoscope, 127:2279–2281, 2017.
