The anterior and posterior branches of the deep temporal artery travel with the middle temporal artery, deep in the temporalis muscle, diminishing in diameter on their upward journey. The middle part of the maxillary artery gives rise to the anterior and posterior deep temporal arteries, which run cranially between the temporalis muscle and the pericranium.These branches supply the temporalis muscle and anastomose with the branches of the middle temporal artery from the superficial temporal artery.The anterior deep temporal artery communicates with the branches of the lacrimal artery through small branches that perforate the greater wing of the sphenoid and zygomatic bones.

Surgical Anatomy Pearls: The temporalis muscle as a muscle of mastication must be strongly anchored to the underlying temporal bone to generate significant upward pull on the coronoid process of the mandible. As such, the superior portion of the muscle is firmly adherent to the underlying bone and devoid of interposing fascia. The periosteum and deep fascia of the forehead (galea aponeurotica) as they traverse the upper face under the frontalis muscle cannot continue under the temporalis muscle and as such lie over the muscle as the deep and superficial temporal fascia respectively. This anatomical oddity, of a deep fascia lying on the surface of the muscle which bears its name, provides a resistant plane that is appreciably felt when penetrating the region with a needle. Overlying this fascia in the posterior leaves of the superficial temporal fascia are the superficial temporal vessels (arteries and veins) and specifically the frontal ramus of the superficial temporal artery. Located in the depth of the muscle are the anterior and posterior deep temporal arteries (branches of the internal maxillary artery, second division), the middle temporal artery (connecting the deep and superficial arterial system), and the prominent middle temporal vein approximately 2 cm above the zygomatic arch. Deposition of botulinum toxin deep to the fascial layer is mandatory to access the bulky deep muscle as outlined above, and will require a 30-gauge needle of minimum ½ inch length. Prudent technique would require aspiration before injection of toxin into the temporal muscle to minimize the possibility of intravascular washout limiting the clinical result. Post-injection pressure for several minutes, regardless of the appearance of blood through the puncture site, will diminish the possibility of delayed unsightly bruising.

Preoperatively the patient underwent computed tomographic angiography (CTA) of the head which was used for intraoperative navigation and localisation of the IMAX (Figure 2). Under general anaesthesia, the patient was positioned supine, with the head in the Mayfield head holder and rotated approximately 45 degrees towards the contralateral side. The previous left frontotemporal incision and pterional craniotomy were reopened. The temporalis muscle was reflected inferiorly and a zygomatic arch osteotomy was performed. Under the operating microscope, a temporal fossa craniectomy was performed consisting of removal of bone of the lateral part of middle cranial fossa floor extending medially as far as a line connecting the foramen rotundum and foramen ovale (Figures 3 and 4). The left IMAX was localised in the infratemporal fossa using a combination of CTA-based neuronavigation and micro-Doppler probe (Mizuho Inc. Tokyo, Japan) (Figure 5). In addition, the deep temporal arteries in the deep aspect of the temporalis muscle were followed proximally to lead to the location of the IMAX.

High resolution magnetic resonance imaging (MRI) technology is rapidly evolving. When compared to TAB, a cohort of mixed 1.5 Tesla (1.5T) and 3 Tesla (3T) MRI showed a sensitivity and specificity of 88% and 75% respectively [88]. The 7 Tesla MRI has shown greater sensitivity than the 3T MRI [45]. These high-resolution MRIs may pick up inflammation in deep temporal arteries when superficial temporal arteries appear unaffected. However, use of such technology is limited by the clinical availability of such machines [45].
