Gradenigo syndrome

Gra·de·ni·go syn·drome

(grah-dā'nē-go),
a syndrome consisting of otorrhea, headache, diplopia, and retroorbital pain in petrositis due to an epidural abscess at the apex of the anterior surface of the petrous pyramid causing compression of the abducens nerve in Dorello canal and irritation of the trigeminal ganglion.

Gradenigo syndrome (Gradenigo-Lannois Syndrome) was described in 1907 by Giuseppe Gradenigo when he reported a triad of symptoms characterised by periorbital unilateral pain due to trigeminal nerve involvement at Meckel's cave, diplopia due to involvement of abducens nerve in Dorello's canal and persistent otorrhoea of involved ear.
