[Emergencies in orbital complications of sinusitis].

Sixty to 80% of orbital infections are secondary to sinusitis. That sinusitis can be everwhelming. Some symptoms must incite us to a quick response: the general state of the patient, his temperature, chemosis, cornean anaesthesia, mydriasis, ocular motor palsy, exophthalmia. We believe that ocular motor palsy and exophtalmia are imperative symptoms. In such cases, it is not only necessary to drain the sinuses, but also to explore the orbit by an external approach with an antibiotic cover.
