September 1, 2022 updated by: Marmara University

Elaborated Analysis of Short and Long-term Results of Skin Versus Skin Plus Orbicularis Resection Blepharoplasty on Corneal Nerves, Meibomian Glands, Dry Eye Parameters, and Eyebrow Position

This study aims to evaluate the short and long-term effects of skin-only and skin+muscle excision blepharoplasty on corneal nerves, dry eye parameters, meibomian glands, and eyebrow position.

Detailed Description

The study was designed with the approval of the Ethics Committee on Human Research of Marmara University and was conducted following the tenets of the Declaration of Helsinki. Written informed consent was obtained from all patients who received information about the procedure and the postoperative course. The study included 48 eyes of 24 patients older than 18 who applied to Marmara University Oculoplastic and Orbital Surgery Unit due to dermatochalasis and were suggested upper eyelid blepharoplasty for medical or cosmetic purposes. The patients were divided into two groups, Group S (n=12) for skin excision only and Group M (n=12) for skin+muscle excision by the decision of the surgeon. In addition to all ophthalmological examinations, sub-basal nerve plexus parameters with corneal confocal microscopy, Schirmer I test, non-invasive tear break-up time, meibomian gland area loss measurements with infrared meibography, central eyebrow height, and lateral eyebrow height were evaluated at baseline and postoperative 1st week, 1st month and 1st-year follow-ups.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Skin-Only Blepharoplasty
Only the skin excision was performed for upper eyelid dermatochalasis.
Procedure: Upper Eyelid Blepharoplasty
Blepharoplasty is a procedure that the skin, orbicularis oculi muscle, and fat pads are excised to treat visual field loss caused by dermatochalasis.
Active Comparator: Skin+Muscle Blepharoplasty
Skin plus muscle excision was performed for upper eyelid dermatochalasis.
Procedure: Upper Eyelid Blepharoplasty
Blepharoplasty is a procedure that the skin, orbicularis oculi muscle, and fat pads are excised to treat visual field loss caused by dermatochalasis.
