Absence of bone over the geniculate ganglion.
Journal of Neurosurgery, 1968D ANDY recognized that the geniculate ganglion "occasionally" protrudes through a congenital defect in the roof of the petrous temporal bone. In their book on trigeminal neuralgia, Stookey and Ransohoff 16 noted that in rare instances the petrous bone is defective over the geniculate ganglion.

Enlarged geniculate ganglion fossa: CT sign of facial nerve canal fracture.
Academic Radiology, 2012The aim of this study was to preliminarily investigate whether an enlarged geniculate ganglion fossa (GGF) on temporal bone computed tomography can diagnose GGF fracture in patients with traumatic facial paralysis by evaluating the diameter of the GGF.Thirty-six patients who underwent computed tomography before confirmation of GGF fracture on otologic ...

Experimental viral infections of the facial nerve and geniculate ganglion
Annals of Neurology, 1981AbstractAlthough the cause of Bell's palsy is in most cases unknown, a number of viral infections have been associated with the disease. To determine if human viruses could experimentally infect the facial nerve or ganglion, six different viruses were inoculated into newborn hamsters by intracerebral, intralabyrinthine, or intraperitoneal routes.

Geniculate ganglion meningioma
Pediatric Radiology, 1997Primary ectopic meningiomas are rare, but may be seen in the head and neck region. The temporal bone and its neural foramen are rarely the site of a primary meningioma. This report describes the CT and MRI appearance of an ectopic meningioma arising at the anatomic location of the geniculate ganglion, and discusses the differential diagnosis as well as

Haemangiomas of the Geniculate Ganglion
Acta Otorrinolaringologica (English Edition), 2007About 60 cases have been published since Pulec first described hemangiomas of the geniculate ganglion. They usually cause facial weakness even when they are very small. In cases of insidious evolution of facial paralysis, MRI, and CT are very helpful to rule out these tumors.

The Ultrastructure of the Geniculate Ganglion
Acta Oto-Laryngologica, 1982The ultrastructure of the geniculate ganglion was studied in the guinea pig and monkey. Two cytologically distinct colonies of ganglion cells were seen and identified as light and dark cells. All neurons were unmyelinated and most were unipolar, although a few bipolar cells were seen. The axons, upon leaving the cell bodies, followed convoluted courses

Endoscopic approach to geniculate ganglion: a multicentric experience
European Archives of Oto-Rhino-Laryngology, 2023A variety of lesions could arise from the GG area, or extend into this region from adjacent sites. The management of perigeniculate lesions includes observation, surgery, and radiation, according to the nature, the size of the lesion, and the accompanying symptoms.

Neurotrophin receptors in the geniculate ganglion
Molecular Brain Research, 1999We examined the distribution of the high affinity neurotrophin receptors (trkA, trkB, and trkC) in the rat geniculate ganglion. Previous work had shown that during early (prenatal) development, trkB and its two ligands, BDNF and NT-4/5, were most important for survival of almost all neurons.
