Introduction: To describe epidemiology of osteo-meningeal breaches and to determine diagnosis and
Method: Retrospective study from January 1, 2001 to December 31, 2009 on patients who presented a
rhinoliquorrhea or otoliquorrhea at Ear Nose Throat and neurosurgery departments of Hubert Koutoukou Maga
National Teaching Hospital of Cotonou.
Results: Twenty-three patients were identified among whom 3 inflammatory and 20 post traumatic that included
a surgery on 1 case of right ethmoido-frontal mucocel. The sex ratio was 19/4 and average age 37.48 years, with
age range from 22 to 61. Thirteen patients underwent TDM which showed a defect: ethmoidal (6), frontal (1), frontoethmoidal
(2), sphenoidal (3), temporal (1).Prophylactic antibiotic therapy and medical monitoring practiced by
patients associated to surgery (6): levying of frontal sinking (3), plastic surgery by abdominal grease (3) with a case
of meningocele resection. Follow up period marked by spontaneous depletion (14), post- surgery resolution (5),
persistence of liquorrhea after surgery (1), death without depletion out of surgery (2), leaving against medical notice
in spite of persistence of liquorrhea (1).
Conclusion: Cranial skull traumatisms dominate the causes of osteo meningeal breaches. Theirs manifestations
were liquorrhea. The medical imagery is primordial in diagnosis and the treatment medical is associated to surgery.
