RESUMO
OBJECTIVES/HYPOTHESIS: To identify factors associated to increased risk of extra-laryngeal spread in pediatric patients with recurrent respiratory papillomatosis (RRP). STUDY DESIGN: Retrospective chart review. METHODS: A retrospective study was conducted evaluating the clinical charts of patients younger than 16 years with histopathologically confirmed RRP treated between January 2014 and December 2018. Characteristics of patients with and without extra-laryngeal disease dissemination were compared. Odds ratios were calculated and multivariate logistic regression analysis was performed. RESULTS: Data from 82 patients were analyzed. Mean age at symptom onset was 42 months. Fifteen (18.29%) patients had extra-laryngeal spread (ELS) at time of diagnosis and in four, the disease continued to spread to other sites. Of 67 patients with disease restricted to the larynx, 17 (25.37%) developed ELS during the disease course. Human papilloma virus (HPV) typing was performed in 49 (59.8%) patients; in 28 (57.1%) HPV subtype 6 was identified and in 21 (42.9%) HPV subtype 11. ELS was found in 11 patients with serotype 11 (52.38%) and in seven patients with serotype 6 (25%) (P = .048). Statistically significant differences for ELS were also found for age at diagnosis younger than 5 years (P = .045), presence of tracheostomy (P = .031), and need for adjuvant therapy (P = .010). CONCLUSIONS: Age at diagnosis of RRP younger than 5 years and presence of tracheostomy were factors related to ELS. A statistically significant association between infection with HPV subtype 11 and ELS were also observed. Adjuvant medication might be considered a protective factor against ELS.

La estenosis subglótica es una de las causas más frecuentes de obstrucción de la vía aérea en pediatría. El 90% son secundarias a la intubación endotraqueal. El diagnóstico se sustenta en la clínica del paciente, la evaluación radiológica, la laringoscopía flexible y la endoscopía rígida de la vía aérea bajo anestesia general. Debe sospecharse en niños con dificultad respiratoria posextubación. La conducta terapéutica dependerá de la gravedad de la estenosis subglótica y de la sintomatología del paciente. Describimos nuestra experiencia en cuanto a las etiologías de las estenosis subglóticas, el diagnóstico, el tratamiento y la evolución de pacientes con esta patología.(AU)
Subglottic stenosis is among the most common causes of airway obstruction in children, 90% of which resulting from endotracheal intubation. The diagnosis is based on the patients clinical, radiologic evaluation, flexible laryngoscopy and rigid airway endoscopy under general anesthesia. It must be suspected in children with respiratory distress after extubation. The therapeutic approach depends on the severity of the subglottic stenosis and the patients symptoms. We describe our experience with the subglottic stenosis etiologies, diagnosis, treatment and outcome of patients with this condition.(AU)
