ABSTRACT

SUMMARY:

The auriculotemporal nerve (ATN) is an important structure lying within a limited area of an infratemporal region (ITR). The ATN is originated from the posterior branch of the mandibular division of the trigeminal nerve (V3). The ATN conveys somatosensory, secretomotor, and parasympathetic fibres of the V3 and gustatory nerve (CN IX). In literature, the most common pattern of the ATN is composed of 2 roots that encloses the middle meningeal artery (MMA). However, in many studies, it has been reported that there are many variations in ATN pattern formation. To study the variation of ATN pattern formation in Thai cadavers, 73 hemifaces from 39 Thai embalmed cadavers were dissected and the relations of the ATN to the MMA were recorded. This study concluded that there were 4 patterns observed in Thai cadavers. The common pattern is 2 roots (67.1 %), 3 roots (15.1 %), 1 root (9.6 %), and 4 roots (8.2 %). Knowledge of this variation in the ATN may be useful in understanding the symptoms of temporo-orofacial pain, paresthesia of temporomandibular joint (TMJ), possible side effects from the TMJ surgery and the efficiency of auriculotemporal nerve block for regional anesthesia of the temporomandibular joint in Thai people.
RESUMEN
RESUMEN El nervio auriculotemporal (NAT) es una estructura importante que se encuentra dentro de la región infratemporal (ITR). El NAT se origina en la rama posterior de la división mandibular del nervio trigémino (V3), y transmite fibras somato sensoriales, secreto motoras y parasimpáticas del V3 y del nervio gustativo (CN IX). En la literatura, se reporta que el patrón más común de NAT está compuesto por 2 raíces que contienen la arteria meníngea media (AMM). Sin embargo, en diversos estudios, se ha informado que existen múltiples variaciones en la for- mación de patrones NAT. Con el objetivo de estudiar la variación de la formación del patrón NAT en cadáveres tailandeses, se disecaron 73 estructuras hemi faciales de 39 cadáveres tailandeses y se registraron las relaciones del NAT con el AMM. En conclusión, se observaron 4 patrones en los cadáveres tailandeses. El patrón común de 2 raíces (67,1 %), 3 raíces (15,1 %), 1 raíz (9,6 %) y 4 raíces (8,2 %). El conocimiento de esta variación en el NAT puede ser útil para comprender los síntomas de dolor temporo-orofacial, parestesia de la articulación temporomandibular (ATM), posibles efectos secundarios de la cirugía de ATM y la eficacia del bloqueo del nervio auriculo-temporal para la anestesia regional de la articulación temporomandibular en Tailandeses.
