Nerve Entrapment Headaches at the Temple: Zygomaticotemporal and/or Auriculotemporal Nerve?
Pain Physician, 2019Co-Authors: Andrea M. TrescotAbstract:Background: Temple headaches are common, yet the anatomic etiology of headaches in this region is often confusing. One possible cause of temple headaches is dysfunction of the auriculotemporal Nerve (ATN), a branch of the third division of the trigeminal Nerve. However, the site of pain is often anterior to the described path of the ATN, and corresponds more closely to a portion of the path of a small branch of the second division of the trigeminal Nerve called the Zygomaticotemporal Nerve (ZTN) Objectives: We present the anatomic and clinical differences between these 2 Nerves and describe treatment approaches. Diagnosis is made by physical examination of the temporal fossa and the temporomandibular joint, and injection of local anesthetic over the tenderest Nerve. Results: In general, treatments of headaches that generated from the peripheral Nerve attempt to neutralize the pain origin using surgical or interventional pain techniques to reduce Nerve irritation and subsequently deactivate stimulated migraine centers. Conclusions: Treatment of temporal Nerve entrapment includes medications, Nerve injections, dental appliances, cryoneuroablation, chemical neurolysis, neuromodulation, and surgical decompression. Key Words: Headache, migraine, trigeminal Nerve, Frey’s syndrome, Zygomaticotemporal Nerve, auriculotemporal Nerve, temple pain, jaw pain, ear pain, tooth pain

The Zygomaticotemporal Nerve and its relevance to neurosurgery.
World neurosurgery, 2011Co-Authors: R. Shane Tubbs, Martin M. Mortazavi, Mohammadali Mohajel Shoja, Marios Loukas, Aaron A. Cohen-gadolAbstract:Background Although neurosurgical procedures are frequently performed in its territory, the Zygomaticotemporal Nerve (ZTN) is rarely mentioned in this literature, even though this Nerve has been implicated in postsurgical pain syndromes and may become entrapped, resulting in chronic headache. The present study was performed to further elucidate the anatomy of the ZTN. Methods Twelve cadavers (24 sides) underwent dissection of the lateral temporal region to analyze the course, relationships, and landmarks for the ZTN. Results A ZTN was found on all but 1 left side. This Nerve left the lateral zygoma to enter the temporal fossa and ascended up through the temporalis muscle or between this muscle and its outer fascia to become subcutaneous near the pterion. Fascial or muscle penetration occurred at a mean of 2.3 cm superior to the zygomatic arch. The majority of Nerves then coursed posteriorly, approximately parallel to the frontoparietal suture of the pterion. The mean distance from the ZTN to the frontozygomatic suture was 12 mm. Conclusions Based on our study, the ZTN has a fairly standard course that takes it along a superficial pathway overlying the pterion. It is our hope that with a greater appreciation for its anatomy and landmarks for its localization as provided herein, that injury to the ZTN may be avoided with surgical procedures in its territory, and if entrapped, may be more easily identified by the surgeon.

Silent squamous cell carcinoma invading the orbit following the course of the Zygomaticotemporal Nerve.
Orbit (Amsterdam Netherlands), 2014Co-Authors: Ronald O B De Keizer, Didi De Wolff-rouendaal, Rob J. W. De KeizerAbstract:AbstractPurpose: To evaluate the clinical and histopathological characteristics of silent skin squamous cell carcinomas (SCC) with invasion routes to the orbit.Methods: Retrospective case studies. Clinical records and histopathological material, therapy and complications were evaluated, together with MRI imaging analyses and literature review on the anatomy of the lateral orbital wall in relation to the zygomatico-temporal Nerve channel.Results: Two recent cases of metastatic SCC from het lateral zygomatic region to het orbit are reported. Originally the skin tumors of the first case was diagnosed as benign, but a review of the pathology of these skin tumors showed an invasive SCC. The second case was diagnosed as an atypical SCC. Analysis of possible invasion routes, using both computer tomography (CT) and magnetic resonance imaging (MRI), indicated neither skin nor bone involvement. However, the lateral temporal fossa near the entrance of the zygomatico-temporal channel showed small tumors and pseudo-cy...

Silent squamous cell carcinoma invaded into the orbit via the perineural space of the zygomatemporal Nerve
Acta Ophthalmologica Scandinavica, 2007Co-Authors: Rjw De Keizer, J Sluimers, Didi De Wolff-rouendaalAbstract:Purpose: Describing two patients who presented with a silent skin tumour invaded into the orbit via an unusual route. Methods: Retrospective case report. We present two patients, one with an immunosuppressive medical history, the other without a relevant history. Results: The two patients present with a tumour which appears to be a tear gland carcinoma. After histology of the biopsies in both patients a squamous cell carcinoma was found. Reviewing original pathology taken two years before admission taken from the patients because of (benign) skin tumours of the temporal side of the orbit demonstrated invasive squamous cell carcinoma. Analysis of possible invasion routes no skin or bone involvement was found neither on CT or MRI. But the lateral fossa near the entrance of the zygomatico-temporal channel showed very small tumours. The course of the zygomatico-temporal Nerve is exactly in line with the original skin tumour, the channel and the orbital tumours. The extension of the tumour was in both cases up to the infraorbital fissure, so radical surgery was an illusion. We gave extended radiotherapy involving the cavernous sinus. Conclusions: We found a special route of invading the orbit by a common skin tumour using the course of the Zygomaticotemporal Nerve. The time elapsed between removing the original tumour and the extension in the orbit took more than two years.

Perineural invasion of cutaneous squamous cell carcinoma along the Zygomaticotemporal Nerve.
Ophthalmic plastic and reconstructive surgery, 2014Co-Authors: Gregory Notz, David Cognetti, Ann P. Murchison, Jurij R. BilykAbstract:The vast majority of periocular squamous cell carcinoma spreads intraorbitally along the supraorbital and infraorbital Nerves into the cavernous sinus. A patient presented with a history of resected squamous cell carcinoma and pain in the zygomatic distribution. She was found to have temporalis involvement of the malignancy and invasion of the Zygomaticotemporal Nerve by histopathology. She underwent aggressive resection and adjuvant treatment with no evidence of recurrence at 8-month follow up. This case illustrates an uncommon route of squamous cell carcinoma spread through the Zygomaticotemporal sensory Nerve distribution.
