Summary
The frontozygomatic approach effectively removed 12 intraorbital tumors with minimal complications. This surgical technique offers a wide view of the optic nerve, proving beneficial for complex orbital tumor cases.
Area of Science:
- Neurosurgery
- Ophthalmology
- Oncology
Background:
- Intraorbital tumors present significant surgical challenges due to limited access.
- The frontozygomatic approach is a less common but potentially effective method for orbital tumor resection.
Purpose of the Study:
- To evaluate the efficacy and safety of the frontozygomatic approach for resecting various intraorbital tumors.
- To highlight the indications and benefits of this surgical technique.
Main Methods:
- Retrospective analysis of 12 patients undergoing tumor removal via the frontozygomatic approach.
- Tumor types included schwannomas, meningiomas, cavernomas, pleomorphic adenoma, and neuroblastoma.
Main Results:
- All 12 intraorbital tumors were successfully removed.
- No mortality occurred; transient ptosis and mild enophthalmos were the main postoperative morbidities.
- Two patients experienced temporary visual acuity and visual field deficits.
Conclusions:
- The frontozygomatic approach provides adequate surgical exposure for intraorbital tumors, including those involving the optic nerve and orbital apex.
- This technique is suitable for large or complex intraorbital tumors and offers advantages in surgical field visualization and surgeon comfort.

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...

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
