Abstract
Introduction and objectives

Nasal dermoids are uncommon midline congenital lesions in the nose, usually diagnosed in the first years of life. Imaging is mandatory to evaluate local and intracranial extension and treatment consists in surgical excision. This study aims to review the experience of the department in managing pediatric nasal dermoids using a dorsal rhinotomy surgical approach.

Material and methods

Retrospective case series of pediatric nasal dermoids treated at a tertiary university teaching hospital over a period of seven years.

Results

Nine children were treated during this period. Clinical presentation was a dermoid sinus-cyst in seven cases and a cystic lesion in two. Pre-operative imaging revealed extension of the lesion to the foramen cecum in three cases. Surgery was performed via vertical dorsal rhinotomy in all patients, and associated endoscopic surgery was used in three patients. Reconstruction with autologous material was performed in three cases. No complications or recurrences were registered during the follow-up.

Conclusions

In the presented series, a vertical dorsal rhinotomy incision has provided good functional and aesthetic results. The possibility of nasal dermoid intracranial extension should be accessed with imaging but remains uncommon. In its absence, this approach may be useful and can be paired with other techniques, such as nasal endoscopy, to achieve the best outcomes.

Resumen
Introducción y objetivos

Los dermoides nasales son lesiones congénitas poco frecuentes de la línea media de la nariz, que suelen diagnosticarse en los primeros años de vida. Las imágenes son obligatorias para evaluar la extensión local e intracraneal y el tratamiento consiste en la escisión quirúrgica. Este estudio tiene como objetivo revisar la experiencia del departamento en el manejo de los dermoides nasales pediátricos mediante un abordaje quirúrgico de rinotomía dorsal.

Material y métodos

Serie de casos retrospectivos de dermoides nasales pediátricos tratados en un hospital universitario de tercer nivel durante un período de siete años.

Resultados

Durante este período se trató a nueve niños. La presentación clínica fue un quiste con seno en siete casos y una lesión quística en dos. Las imágenes preoperatorias revelaron extensión de la lesión al agujero ciego en tres casos. La cirugía se realizó mediante rinotomía dorsal vertical en todos los pacientes y en tres pacientes se utilizó cirugía endoscópica asociada. En tres casos se realizó reconstrucción con material autólogo. No se registraron complicaciones ni recurrencias durante el seguimiento.

Conclusión

En la serie presentada, una incisión de rinotomía dorsal vertical ha proporcionado buenos resultados funcionales y estéticos. Se debe acceder a la posibilidad de extensión intracraneal del dermoide nasal mediante imágenes, pero sigue siendo poco común. En su ausencia, este enfoque puede resultar útil y puede combinarse con otras técnicas, como la endoscopia nasal, para lograr los mejores resultados.
