Resumen
Introducción

Las fístulas espontáneas de LCR no son una entidad frecuente y pueden ser infradiagnosticadas en el adulto. Para algunos autores, debe sospecharse esta patología en cualquier paciente mayor de 50 años con episodios de otitis serosas recurrentes y ausencia de antecedentes otológicos. La meningitis es su complicación más grave, por lo que es prioritario un diagnóstico precoz y certero.

Objetivo

Presentar dos casos clínicos atendidos en nuestro servicio y revisar la literatura científica existente al respecto.

Conclusión

El tratamiento de estas fístulas atraumáticas es eminentemente quirúrgico, pudiendo emplear la craneotomía de fosa media o la vía transmastoidea. En el sellado debe emplearse una técnica multicapa, combinando materiales autólogos y artificiales para conseguir mejores resultados.

Summary
Introduction

Spontaneous cerebrospinal fluid otorrhea is a relatively rare entity and can be easily missed in adults. Every adult older than 50 years with a negative history of otologic disease who has recurrent serous otitis media should be evaluated for this pathology. Meningitis is the most serious complication, so there is no doubt that the condition needs immediate attention and correction.

Objective

We present two patients who were diagnosed with spontaneous CSF otorrhea and make a review of what is reported about this topic.

Conclusion

Surgical repair is mandatory to seal these nontraumatic CSF leaks. There are two main surgical approaches, the middle fossa craniotomy and the transmastoid approach. A multilayered closure technique in which autologous and artificial materials are combined is considered to result in the highest rate of success.
