Summary
Posttraumatic enophthalmos, an eye condition after facial injury, results from orbital fractures enlarging the eye socket. Successful surgical correction requires detailed anatomical knowledge and precise orbital reconstruction.
Area of Science:
- Craniomaxillofacial Surgery
- Ophthalmology
- Medical Imaging
Background:
- Posttraumatic enophthalmos is a common complication following facial trauma.
- Orbital fractures leading to orbital cavity enlargement are the primary cause, with a 1 cm³ volume increase causing 0.8 mm of enophthalmos.
- Surgical correction is challenging due to the need for precise orbital anatomy knowledge to avoid complications.
Purpose of the Study:
- To review the pathophysiology and surgical management of posttraumatic enophthalmos.
- To emphasize the critical role of orbital anatomy in successful surgical outcomes.
- To outline preoperative planning and treatment strategies based on fracture types.
Main Methods:
- Comprehensive clinical examination of periorbital tissues and bony structures.
- Detailed ophthalmic assessment.
- High-resolution computed tomography (CT) scans in axial, coronal, and sagittal planes.
Main Results:
- Two main fracture types causing enophthalmos: orbital blow-out and zygomatico-orbital fractures.
- Treatment approaches are tailored to the severity of orbital deformities.
- Potential complications range from minor (ectropion, diplopia) to severe (blindness).
Conclusions:
- Successful surgical correction hinges on adequate soft tissue mobilization, accurate bony orbit repositioning, and appropriate intra-orbital grafting.
- Thorough understanding of orbital anatomy and meticulous surgical technique are paramount.
- Careful preoperative planning and execution minimize the risk of complications.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
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.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:30Epistaxis
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
