[Topical treatment of otorrhea]. / Tratamiento tópico de las otorreas.

A study has been carried out with 167 cases of discharging ears treated topically by means of lavages with a formic solution followed by the instillation of a quantity of boric drops. The material and methods used are exposed, together with the results achieved, taking into account that most the cases had been previously multi-treated with antibiotherapy, with adverse outcome. This procedure is cheap, effective and with scarce side-effects.
