Percutaneous Vocal Fold Lateralization in children - a case series of a Brazilian tertiary pediatric hospital (pediatric vocal fold lateralization cases in a Brazilian hospital).

Objectives: Percutaneous Vocal Fold Lateralization (PVFL) consists of external fixation with non-absorbable percutaneous suture of the vocal fold in a lateral position, under direct glottic visualization. The objective of this study is to determine the effectiveness of PVFL in a university pediatric hospital, as well as to describe the potential risks and complications of the surgery.

Methods: Retrospective cohort study, with data collected from electronic medical records.

Efficacy and predictors of success on laryngomalacia surgery: experience from a tertiary pediatric care center in Brazil.

Objectives: Laryngomalacia is the most common congenital cause of stridor; the natural history of the disease runs through to complete resolution by the age of two. Severe cases are characterized by cyanosis, hypoxia, apnea, furcular and/or subcostal retractions, aspirations, pulmonary hypertension, and failure to thrive and must undergo surgery. This study aimed to evaluate the success rates of supraglottoplasty in our hospital and evaluate the predictive factors for surgical success.
