It was given by using Ropivacaine 0.5 %.30 ml (max.) to block supraorbital, supratrochlear, zygomaticotemporal, Auriculotemporal
, greater & lesser occipital, greater auricular nerves for better analgesia & perioperative Haemodynamic stability.
Frey's syndrome, also called gustatory sweating or auriculotemporal
syndrome, is a rare disorder that comprises of facial sweating and flushing of the parotid region initiated by gustatory stimulus., This condition is attributed to direct damage of the auriculotemporal
From an anatomical perspective, there are heterogeneous distributions of nerves in the external ear; the cymba is innervated by ABVN, both ABVN and the greater auricular nerve (GAN) are found in the cavum, and at the tragus, three nerves, ABVN, GAN, and auriculotemporal
nerve are observed at the tragus .
(1), six nerves are identified by landmarks on each side of the cranium (supratrochlear, supraorbital, zygomaticotemporal, auriculotemporal
, lesser occipital and greater occipital nerves), and they are subsequently infiltrated with a local anaesthetic dose ranging from 2 to 5 mL.
Bajo anestesia general se prepara asepticamente el campo quirurgico, es conveniente realizar un bloqueo anestesico en los nervios auriculotemporal
y auricular mayor, como lo describe Otero (2006), lo que garantiza mayor analgesia en el area.
In this review, we aimed to summarize the regional anatomy and ultrasound-guided injection techniques for the commonly affected branches of the trigeminal nerve, including the supraorbital, infraorbital, mental, auriculotemporal
, maxillary, and mandibular nerves.
Further, the two roots of the auriculotemporal
nerve looped around it (Figs.
The inferior alveolar, lingual, mylohyoid, mental, incisive, auriculotemporal
, and buccal nerves are all blocked.1,11 Significant advantages of the Gow-Gates technique over IANB include its higher success rate, its lower incidence of positive aspiration (approximately 2% vs.
While assessing relationship of the lesions to surroundings; 25 lesions (34.2%) showed vascular encasement, 20 lesions (27.4%) showed facial nerve involvement, 10 lesions showed perineural spread "8 lesions (10.96%) through facial nerve and the remaining 2 lesions (2.74%) via the auriculotemporal
nerve branch of mandibular division of the trigeminal nerve", 2 lesions (2.74%) showed intracranial extension and 3 lesions (4.1%) were aggressive and showed bone invasion.
The young male was affected by an intraparotid lesion, which oddly did not derive from the peripheral portion of the facial nerve but instead originated from the auriculotemporal
However, this auricular region is supplied not only by ABVN, but also by the auriculotemporal
nerve and contributions of the glossopharyngeal , facial , and cervical nerves (lesser occipital nerves and auricularis maior) [24-26]; importantly, all these nerves contribute to the innervation of the external auditory meatus and external auditory canal, and only the cymba conchae is regarded to be exclusively innervated by ABVN .
