Open Angle Glaucoma: Treatment01:27

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Angle Closure Glaucoma: Treatment01:28

Angle 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...
Glaucoma: Overview01:25

Glaucoma: 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...

Area of Science:

  • Plastic Surgery
  • Otorhinolaryngology

Background:

  • Protruding ears affect approximately 5% of the German population.
  • This condition can lead to significant emotional distress in both children and adults.

Purpose of the Study:

  • To outline surgical approaches for correcting protruding ears (otoplasty).
  • To emphasize individualized treatment based on ear anatomy and patient age.

Main Methods:

  • Surgical correction involves a combination of incision, scoring, and suture techniques.
  • Techniques are selected based on the severity of the ear abnormality and the pliability of the auricular cartilage.
  • Specific methods like Mustardé sutures are used for children, while adults may require more extensive procedures.

Main Results:

  • Otoplasty aims to reduce the cephaloauricular angle, create an antihelical fold, and ensure a smooth helix contour.
  • Gentle suture techniques can yield good results in children with pliable cartilage.
  • Adults often require combined techniques due to stiffer cartilage.

Conclusions:

  • Individualized analysis of each ear's specific issues is crucial for successful otoplasty.
  • The surgical approach should prioritize minimizing injury to the auricular cartilage to prevent deformities.
