Abstract
BACKGROUND
Microtia is a frequent congenital deformity of the pinna, often with hearing loss. This study reviews the clinical profiles of microtia pediatric patients treated at a referral hospital in Quito, Ecuador, from 2015 to 2022.
METHODS
A cross-sectional descriptive study was carried out based on the analysis of medical records of pediatric patients with microtia treated between January 2015 and December 2022 at the Hospital Pediátrico Baca Ortiz in Quito, Ecuador. Descriptive statistics were used, and the Chi-square test assessed associations between categorical variables.
RESULTS
Of the 235 patients evaluated, 59.6% were male, 83.4% lived at high altitudes (2500-3500 m), and 19.1% had a family history of microtia. Grade III microtia was diagnosed in 63.8%, predominantly on the right side. Nearly all (99.1%) had hearing loss. Other anatomical alterations were observed in 27.7%, primarily the preauricular appendage. Bone vibrator implantation was a common treatment for 24.3%. Altitude did not show a significant correlation with microtia characteristics.
CONCLUSIONS
Most patients had grade III microtia with associated hearing loss. Despite the high prevalence at elevated altitudes, no significant altitude-disease correlation was found. The study highlights the need for further research on microtia in regions like Ecuador.
