GALBARRIATU, L. et al. Adult spontaneous cerebrospinal fluid otorrhea: Report of two cases and review of the literature. Neurocirugía [online]. 2011, vol.22, n.2, pp.150-156. ISSN 1130-1473.

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.
