Hallazgos nasosinusales por tomografía computada en dacriocistitis crónica pediátrica. (Spanish)

Naso-sinus findings by computed tomography in pediatric chronic dacryocystitis. (English)

Objective: To evaluate the preoperative tomographic characteristics of the nose and paranasal sinuses of children with chronic dacryocystitis. Method: Prospective, observational, cross-sectional, and descriptive study. CT scans of the paranasal sinuses of patients candidates for endoscopic dacryocystorhinostomy were evaluated for two years. Demographic characteristics, radiological findings, inflammatory processes and anatomical variants were identified using the Lund-Mackay classification. Statistic analysis. Stata 10.0, descriptive analysis, Student's t: mean difference and χ². Logistic studies to estimate the probability between variables. Results: 27 men and 11 women (n = 38) were included. Of these, 22 had unilateral and 16 bilateral nasolacrimal duct involvement. Lund-Mackay score range: 2-20. Eleven patients had associated pathology. The most affected were anterior and maxillary ethmoidal sinus (69%), osteomeatal complex (68%), posterior ethmoidal (51%). Patients with severe rhinosinusitis are 12 times more likely to develop dacryocystitis than patients with < 12 points. Men presented greater severity, affectation, and clinical repercussion. Conclusions: There is radiological rhinosinusal involvement in dacryocystitis, which must be evaluated and treated preoperatively to avoid postoperative complications or reinfections.

Objetivo: Evaluar las características tomográficas preoperatorias de la nariz y los senos paranasales de niños con dacriocistitis crónica. Método: Estudio prospectivo, observacional, transversal y descriptivo. Se evaluaron tomografías de senos paranasales de pacientes candidatos a dacriocistorrinostomía endoscópica, durante 2 años. Se identificaron características demográficas, hallazgos radiológicos, procesos inflamatorios y variantes anatómicas, utilizando la clasificación Lund-Mackay. Análisis estadístico con Stata 10.0, análisis descriptivo con t de Student: diferencia medias y χ². Estudios logísticos para estimar la probabilidad entre variables. Resultados: Se incluyeron 27 hombres y 11 mujeres (n = 38). De ellos, 22 tenían afección del conducto nasolagrimal unilateral y 16 bilateral. Rango de puntuación de Lund-Mackay: 2-20. Once pacientes tuvieron patología asociada. Seno etmoidal anterior y maxilar más afectados (69%), complejo osteomeatal (68%), etmoidal posterior (51%). La probabilidad de que los pacientes con rinosinusitis grave puedan presentar dacriocistitis es 12 veces mayor que en los pacientes con < 12 puntos. Los hombres presentaron mayor gravedad, afectación y repercusión clínica. Conclusiones: Existe afección rinosinusal radiológica en la dacriocistitis, que debe ser evaluada y tratada en el preoperatorio para evitar complicaciones o reinfecciones posquirúrgicas.
