Silent sinus syndrome secondary to a radix relicta in the antrum.

The case of a 57-year-old man with a radix relicta in the maxillary sinus causing a chronic maxillary sinusitis with secondary alteration of orbit and maxillary sinus, compatible with the silent sinus syndrome, is presented. The patient was treated with intranasal antrostomy in which the underlying dental cause of the inflammation was also removed. Initial antrostomy of the affected maxillary sinus may be a good therapy for unilateral enophthalmos with underlying chronic sinusitis, which can lead to spontaneous reduction or even resolution of the enophthalmos.
