Peripheral Autonomic Neuropathies
Published in David Robertson, Italo Biaggioni, Disorders of the Autonomic Nervous System, 2019
The auriculotemporal syndrome is paradoxical reflex gustatory sweating; it occurs after nerve injury in the face. Sweating and flushing of the skin supplied by the auriculotemporal nerve occur during eating, particularly of spicy or sour foods. Because the auriculotemporal nerve carries sympathetic postganglionic fibres to blood vessels and sweat glands, and parasympathetic preganglionic secretomotor fibres to the parotid gland, it may be that reflex sweating during eating is due to cross-excitation between parasympathetic and sympathetic fibres. Successful treatment of this syndrome by division of the ninth cranial nerve has been reported, suggesting that the impulses initiating the abnormal sweating were carried in parasympathetic fibres. The auriculotemporal syndrome has also been attributed to injury of the auriculotemporal nerve by forceps during delivery.
Head and neck
Published in Tor Wo Chiu, Stone’s Plastic Surgery Facts, 2018
Sensation – the auriculotemporal nerve, which is a branch of the mandibular nerve (V3), emerges anterior to the tragus. It also supplies the upper part of the pinna (lower half is supplied by the great auricular nerve; the posterior auricular nerve is a preparotid branch of the VIIth nerve and is motor to occipitalis).

Auriculotemporal nerve - also from the mandibular nerve, has two roots that encircle the middle meningeal artery; the nerve then runs upwards, anterior to the ear, together with the superficial temporal vessels (Fig.3.22) to supply the face and scalp skin above and secretory nerve fibres to the parotid gland below (see above).

Patients were operated in supine position and the forehead was strapped to the operating table with adhesive tapes. A four pin headholder was considered for head fixation in anxious/apprehensive patients. Scalp block was planned according to the site of the burr hole. Local anesthesia (bupivacaine with xylocaine in the ratio 1:1) was infiltrated at ipsilateral supraorbital, supratrochlear, zygomaticotemporal, and auriculotemporal nerve areas. After marking the burr hole position, the incision site was also infiltrated with local anesthesia. ETV was performed with a rigid fiberoptic endoscope using a freehand technique. The stoma was made on the floor of the third ventricle between the mamillary bodies and the dorsum sella with the help of a 5F fogarty (Edwards life science, Irvine, California, USA) with beveled cut end. A 4Fr Fogarty balloon catheter was used to dilate the stoma in all cases. VAS score (Visual analog scale where 0 represents no pain and 10 represents worse imaginable pain) was used to assess patient discomfort during the surgery. CT scan was obtained in all patients before discharge from the hospital.

The neural correlates of VNS remain enigmatic, and imaging studies have produced somewhat inconsistent results. The low temporal and spatial resolutions of the imaging modalities used, varying stimulation parameters, limited sample sizes, and the clinical populations assessed are all potentially confounding factors. In healthy volunteers undergoing nVNS, the aim is to measure changes in the blood oxygenation level dependent (BOLD) response in vagal afferent pathway target regions. To date, at least eight studies using whole-brain exploratory analysis have been reported [58–65]. Using taVNS, some [59–62] but not others [58,63] showed increased BOLD response in the nucleus tractus solitarius (NTS) and LC. Conversely, Kraus and colleagues [59] reported decreased BOLD response in both regions during taVNS. Across these studies, increased activity (during taVNS relative to rest or sham stimulation) has been found in regions encompassing salience (insula, anterior cingulate), basal ganglia (caudate nucleus, putamen), thalamic, and cerebellar brain networks. By contrast, deactivation was observed in the limbic system and temporal lobe when sham stimulation has been compared to active stimulation. It is noteworthy that the exact neural connections of the ABVN are not known. The tragus is innervated, for example, only by the great auricular nerve and the auriculotemporal nerve, not the vagus nerve [66].
NeurHistAlert 24

This brief biographical article also focuses on Łucja Frey-Gottesman, an early female European neurologist. Born in Lemberg in the Austro-Hungarian Empire (today, Lviv in the Ukraine), she attended the University of Warsaw for her medical studies. Frey described the auriculotemporal nerve syndrome named after her in the 1920s. Following the German and Russian occupation of Poland in 1939, she was interned in a Nazi concentration camp and tragically died in the Holocaust.
