Summary
Understanding lateral canthal anatomy, including the lateral canthal tendon and lateral rectus capsulopalpebral fascia, is crucial for safe lateral canthal surgeries. This review details key anatomical structures for surgical success.
Area of Science:
- Ophthalmology
- Anatomy
- Surgical Anatomy
Background:
- The lateral canthus, while analogous to the medial canthus, possesses a less defined anatomical structure.
- Key components include the lateral canthal tendon, lateral rectus capsulopalpebral fascia, and other supporting tissues.
Purpose of the Study:
- To present a comprehensive review of the lateral canthal anatomy.
- To highlight updated anatomical topics relevant to lateral canthal surgery.
Main Methods:
- Literature review of anatomical studies and surgical texts.
- Detailed discussion of specific anatomical landmarks and their significance.
Main Results:
- The lateral canthal tendon is a primary component, but the lateral rectus capsulopalpebral fascia and other ligaments also contribute significantly.
- Identified structures include the lateral orbital thickening, lateral palpebral raphe, lateral canthal muscle, lateral check ligament, lateral retinaculum, and orbitomalar ligament.
Conclusions:
- Accurate knowledge of lateral canthal anatomy is essential for performing safe and effective lateral canthal surgeries.
- This review provides a foundational understanding of these structures for surgeons.

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:20Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
