Rhinologic and otoneurologic tests in the diagnosis of nasal liquorrhea and their significance in the choice of surgical treatment

: Liquorrhea nasalis (LN) is considered by ENT specialists as vasomotor--allergic rhinitis. It is divided into craniosinusonasal and cranionasal. The latter form is more dangerous as to intracranial complications. Otorhinolaryngological and otoneurological examinations of LN patients are essential in the disease diagnosis, evaluation of surgical results (by nasal endoscopy), detection of intranasal medullary hernia, liquor cysts and tumors as well as residual otoneurological symptoms consequent to meningitis, brain trauma, etc. In choice of surgical treatment the attention of the physician should be directed to concomitant intranasal hernias and liquor cysts, tumors, purulent sinusitis. Out of 70 LN cases residual symptoms of olfactory disorders were recorded in 35%, neurosensory hypoacusis in 30% of the cases. The best position of the patient and relevant facilities for identification of even minimal LN are described.
