Summary
A new cosmetic lateral canthoplasty technique effectively lengthens and widens the palpebral fissure by anchoring the retinaculum to the orbital rim. This method offers improved aesthetic results and patient satisfaction with minimal complications.
Area of Science:
- Oculoplastic surgery
- Cosmetic surgery
- Facial aesthetics
Background:
- Previous lateral canthoplasty techniques had limitations in adjustable fixation for palpebral fissure lengthening.
- Anchoring to the palpebral portion can be inconvenient and ineffective for cosmetic lengthening.
- A novel fixation level on the lateral orbital rim is proposed for improved outcomes.
Purpose of the Study:
- To report an effective fixation level of the lateral orbital rim for cosmetic lateral canthoplasty.
- To evaluate the efficacy of a new anchoring method for lengthening and widening the lateral palpebral fissure.
Main Methods:
- Cosmetic lateral canthoplasty was performed on 246 patients (202 women, 44 men) between June 2015 and August 2017.
- The lower lid component of the lateral retinaculum was released and secured to the periosteum of the lateral orbital wall.
- Fixation was performed at the most concave portion of the lateral orbital rim, 1-2 mm below the concavity.
Main Results:
- The procedure was successful in all cases with no severe complications.
- Minor complications were observed in some patients.
- The lateral palpebral fissure achieved a naturally wider and brighter contour, with high patient satisfaction.
Conclusions:
- Anchoring the retinaculum at the most concave portion of the lateral orbital rim consistently yields a wider, brighter lateral palpebral fissure.
- Fixation to the bony orbital rim offers advantages over palpebral fixation, including effective fissure modification, ease of use, symmetry, and reduced over/undercorrection.

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

1.0K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

01:29Leveling Effect
1.4K
In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
