The main causes of JRRP are human papillomavirus (HPV) types 6 and 11. Children infected with HPV 11 appear to be at a higher risk of developing obstructive airway disease. HPV 31 and 33 exhibit intermediate malignant potential. There are 2 forms of RRP, with the most aggressive form occurring in children. The presentation in the first 28 days of life poses higher right for tracheostomy and attendant morbidity and mortality. Diagnosis before versus after 3 years of age is associated with 3.6 times greater likelihood of needing more than four surgical procedures per year.
The first and most predominant site of the papilloma in the vocal fold making hoarseness the principal presenting symptom. Stridor (noisey breathing) is often the second clinical symptom to develop.
Some of the less common presenting symptoms are chromic cough, recurrent pneumonia, failure to thrive, dyspnea, dysphagia, or acute respiratory distress, especially in infants with upper respiratory tract infection.
At times, JRRP can be misdiagnosed as asthma, croup, allergies, vocal nodules, or bronchitis.
Tracking of the JRRP is a challenge. The history of the disease shows that is it highly unpredictable. It has a spontaneous remission rate and can only be stabilized when the patient undergoes periodic surgical treatments. Those treatments must be aggressive and require surgical treatments every fews days to weeks and suggest an additional consideration of additional supportive medical therapy.
The only way to properly diagnosis JRRP is through a biopsy. Once a biopsy is completed and the diagnosis made, a treatment plan can be made. The goals for treatment are to improve the airway and voice and serial debulking (the removal of portion of a growth which can not be fully removed). Unfortunately, JRRP will reoccur but in order the try to control the disease, parents are encouraged to keep good records on the child to help understand how each child is doing in the longterm.
