“…In addition, auriculotemporal syndrome is often mistaken for tic douloureux due to gustatoria sweating, facial flushing, and pain (De Benedittis, 1990). Variations in the anatomy of the auriculotemporal nerve are of great importance in the regional anesthesia applications to the auriculotemporal nerve and the temporomandibular joint (Donlon et al, 1984;Isberg et al, 1987). With this information, the failures in surgical interventions and anesthetic agent applications, despite adhering to the routine procedures, may be accounted for.…”

Variations in the anatomy of the auriculotemporal nerve

The common representation of the auriculotemporal nerve is either that of a single posterior branch of the mandibular nerve or of two roots that envelope the middle meningeal artery. Our observation in the anatomy of the auriculotemporal nerve on 32 dissections (16 cadaveric heads) of the infratemporal fossa included: one specimen with four roots (3.1%), three specimens with three roots (9.4%), 12 specimens with two roots (37.5%), and 16 specimens with one root (50%). Furthermore, a connecting nerve branch was observed between auriculotemporal and inferior alveolar nerves in four specimens, and in another auriculotemporal nerve case, between the upper and lower roots. In the cadaver of a 70-year-old male, a four-rooted auriculotemporal nerve variation was found. These four branches lay to the posterior, combined at the posterosuperior of the maxillary and superficial temporal arteries and formed a ganglion-like knot. From this knot, four branches stemmed and ran to the temporomandibular joint, external acoustic meatus, zygoma, and parotid gland. The knot was larger and thicker than expected; thus, it was removed and stained with haematoxylin-eosin (H&E) and S100 for histological studies. This structure was not a true ganglion but a structure formed by fusion of nerve fibers.

“…Although studies of Dolon et al (20) showed complications such as: 2% (1/50) subcutaneous hematoma, 14% (7/50) of zigomaticotemporal paralysis and 24% (12/50) of the orbicular muscle paralysis and no positive aspiration. The high rate of paralysis of the facial nerve can be justified by the close contact of nerve facial with the auriculotemporal nerve observed in others studies (27,28).…”

“…Several studies reported findings of the anesthetic blockage of this nerve to perform artrocenthesis and arthrography, but none has studied the anesthetic blockage as an option for treating TMD´s, which makes only possible the discussion about its complications. One of these studies was made by Dolon et al (20) who made 60 anesthetics blockages in 50 patients to perform arthrography and artrocentese. Out of these, 20% of patients (10/50) reported discomfort at the beginning or at end of the procedure and 8% (4/50) reported pain during the procedure.…”

“…Then the patients were asked to open the mouth as wide as possible to find the condylar neck, approximately 1-1.5 cm below the tragus (19,20). The needle is passed through the skin about 4 mm in front of the tragal cartilage and directed inward and forward until the condyle is felt by the need tip that passed behind the neck of the condyle for a further penetration of 1 cm, where 1 ml of solution is deposited in the region of the auriculotemporal nerve.…”

The anesthetic was deposited at this point after negative aspiration (20). …”

Purpose: the aim of this study was to evaluate the use of physical therapy and anesthetic blockage of the auriculotemporal nerve as a treatment for temporomandibular joint disorders. Methods: the sample comprised of twenty patients with a diagnosis of disc displacement with/ without reduction and arthralgia according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD Axis I Group IIa, IIb and IIIa). Ten patients (group 1) underwent a cycle of eight anesthetic blockages of the auriculotemporal nerve with injections (1 per week) of 1 ml of bupivacaine 0.5% without vasoconstrictor for 8 weeks. The other 10 patients (group 2) received anesthetic blockage and physical therapy (massage and muscular stretching exercises). After the end of treatment all patients were evaluated at baseline, 1st week, 4th week and 2 months. The t-Student and F (ANOVA) tests were used for statistical analysis, with a significance rate of 5%. Results: there was a significant difference when both groups were compared according to VAS score (p=0.027). There was no significant difference for the other variables: MMO and jaw protrusion. Conclusion: the anesthetic blockage and physical therapy, when used together, are effective in the reduction of pain in patients with TMD. Key words:Temporomandibular joint disorders, physical therapy, physiotherapy and nerve block, local anesthetic, bupivacaine.
