The Temple (Temporal Region)
The area above your ears where glasses typically rest is called the temple or temporal region. This anatomical area corresponds to the temporal fossa, which overlies the temporal bone of the skull 1, 2.
Anatomical Details
The temporal region is a complex anatomical area that includes:
- The temporal fossa - a shallow depression on the lateral aspect of the skull where eyeglass temples (the arms of the glasses) typically rest 1, 2
- The temporal bone - one of the more complex structures at the skull base that forms the foundation of this region 3
- Multiple tissue layers - including skin, subcutaneous tissue, temporalis muscle, and underlying bone 2
Clinical Relevance to Eyewear
The temporal region is specifically relevant when fitting eyeglasses:
- Eyeglass temples (arms) rest on this area and extend posteriorly toward the ear 4
- Thick temples and frames can significantly impact the temporal visual field, with studies showing up to a 33% reduction in the temporal quadrant when wearing sunglasses with thick plastic frames and wide temples compared to thin frames 4
- Cable temples are sometimes used in children's eyeglasses to improve fit and retention in this area 5
Important Nerves in This Region
The temporal area contains important sensory nerves that can be relevant clinically:
- The zygomaticotemporal nerve (ZTN) - a branch of the second division of the trigeminal nerve that runs through the anterior portion of the temporal region 1
- The auriculotemporal nerve (ATN) - a branch of the third division of the trigeminal nerve located more posteriorly near the ear 1
These nerves can be sources of temple headaches or discomfort, which may be exacerbated by poorly fitting eyeglass temples 1.
