Histologic Comparison of Upper Blepharoplasty Skin Excision Using Scalpel Incision Versus Microdissection...

Area of Science:

• Ophthalmology
• Plastic Surgery
• Dermatopathology

Background:

• Upper blepharoplasty techniques vary, with limited comparative histologic data.
• Previous studies focused on surgical outcomes, not tissue histology.
• No study has histologically compared scalpel, microdissection electrocautery, and CO2 laser excision in the same patient.

Purpose of the Study:

• To histologically evaluate upper eyelid skin excised by scalpel, microdissection electrocautery needle, and CO2 laser.
• To compare the degree of thermal injury and artifact induced by each method.

Main Methods:

• Histologic examination of upper eyelid skin specimens from blepharoplasty.
• Specimens obtained using scalpel, microdissection needle with electrocautery, and CO2 laser.
• Permanent sectioning and evaluation for cellular changes and thermal artifact.

Main Results:

• Scalpel excision showed no cellular necrosis or thermal artifact.
• CO2 laser treatment resulted in significant thermal injury, including necrosis and epidermal separation.
• Microdissection electrocautery caused fulguration artifact with minimal necrosis.

Conclusions:

• CO2 laser causes the most significant histologic tissue injury.
• Microdissection electrocautery results in moderate thermal artifact.
• Scalpel excision is the least damaging method histologically.
