DECUADRO-SAENZ, G. et al. Auriculo temporal nerve: Neuroanatomic bases of the Frey' Syndrome. Neurocirugía [online]. 2008, vol.19, n.3, pp.218-232. ISSN 1130-1473.

The aim of this study was to precise the relationships of the auriculotemporal nerve in the infratemporal and parotid regions. We realized micro-dissections of thirty-two infratemporal and parotid regions of human cadaver's formol-fixed. The pattern of origin was: one root: 15.4%, two roots: 73.1%, three roots: 11.5%. In all cases, the lateral root present the major diameter (2-2,5 mm). In those cases with two roots, these formed a neural loop round the middle meningeal artery in the 89.4% of the cases. The origin of the medial root was the posterior border of the inferior alveolar nerve. The median distance between the lateral root and the temporomandibular joint capsule was 1.5 mm, with asymmetric pattern: right: 2 mm (rank: 0-7 mm; ED: 1.90mm); left: 1.25 mm (rank: 0-3 mm; ED: 0.88 mm). In 10 cases (31.3%) the lateral root was in direct contact with the articular capsule, with asymmetric pattern: left: 46.1%; right: 21%. The median distance between the superior aspect of the articular disk and the trunk of the auriculotemporal nerve in the posterior aspect of the temporomandibular joint was 10,5 mm (ED: 4.06 mm), with asymmetric pattern: right: 9 mm (rank: 5-18.0 mm; ED: 3.70 mm); left: 11.0 mm (rank: 3.0-20 mm; ED: 4.41 mm). We discussed the rol of this findings in the etiology of the Frey's syndrome.
