Effects of Midcheek Lift According to Dissection Plane and Range: An Anatomical Study
Aesthetic Surgery Journal
|December 21, 2023
Summary
This study compared preperiosteal and subperiosteal dissection for midcheek lifts. While preperiosteal dissection offered greater lift initially, full dissections showed no significant difference, especially laterally.
Area of Science:
- Plastic Surgery
- Anatomy
- Surgical Techniques
Background:
- Midcheek lift is utilized in cosmetic and reconstructive lower eyelid surgery.
- Preperiosteal and subperiosteal dissections are common for midcheek lift via subciliary incision, yielding good outcomes.
- A direct comparison of these two dissection planes was previously lacking.
Purpose of the Study:
- To compare the efficacy of preperiosteal versus subperiosteal dissection planes for midcheek lift.
- To evaluate the impact of varying dissection ranges on midcheek lift outcomes.
Main Methods:
- Forty hemifaces from 20 cadavers were dissected.
- One side underwent preperiosteal dissection, the contralateral side underwent subperiosteal dissection.
- Measurements of the elevated lid-cheek junction were taken after dissections of 5, 10, 15, 20, 30 mm, and full midcheek area dissection.
Main Results:
- Midcheek lift length increased with dissection progression in both methods.
- Lateral dissection consistently yielded greater lift length than medial dissection.
- In full dissections, no statistically significant difference in midcheek lift length was observed between preperiosteal and subperiosteal methods, particularly on the lateral aspect.
Conclusions:
- Flap elevation in lower blepharoplasty can be predicted by surgical method and dissection extent.
- Tailoring surgical plans based on dissection plane and range can optimize outcomes in midcheek reconstruction and aesthetics.

2.1K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...
