Objectives: The lesion distribution of juvenile-onset recurrent respiratory papillomatosis (JORRP) during first-time surgery has been rarely reported. The purpose of this study was to describe the anatomical distribution of papilloma across 25 Derkay sites during initial surgery and to assess the impact of the lesion distribution on disease severity.
Methods: Surgical videos and medical records of 106 patients with JORRP (27 aggressive and 79 nonaggressive cases) were retrospectively reviewed. Lesion locations were recorded using Derkay anatomical sites. Logistic regression was used to analyze the effect of the lesion distribution on disease severity.
Results: Among the 106 patients, the true vocal cords (90.6% left, 84.0% right) were the most frequently involved site, followed by the false vocal cords (39.6% left, 35.8% right) and the anterior commissure (26.4%). Two patients (1.9%) had tracheal involvement. Patients with false vocal cord involvement (odds ratio [OR] = 3.425, 95% confidence interval [CI] [1.285, 9.132], P = .014) and a younger age at diagnosis (OR = .698, 95% CI [.539, .905], P = .007) were more likely to require more than 4 procedures in the year following first-time surgery.
Conclusions: Lesions were most common on the true vocal cords. False vocal cord involvement and a younger age at diagnosis were risk factors for disease severity.
