This study details perioral arterial anatomy, revealing new flaps for lip reconstruction. These vascularized flaps offer improved options for repairing defects in the upper and lower lips.

Area of Science:

Anatomy
Vascular Surgery
Reconstructive Surgery

Background:

The perioral region's vascular supply is crucial for reconstructive procedures.
Understanding facial artery branches is key for effective flap design.

Purpose of the Study:

To investigate the vascular anatomy of the perioral region.
To propose novel regional flaps based on identified arterial branches for lip reconstruction.

Main Methods:

Dissection of fresh cadavers to meticulously map perioral arterial pathways.
Identification and description of septal, alar, and labiomental branches of the facial artery.

Main Results:

Consistent identification of septal and alar branches supplying the upper lip.

Related Experiment Videos

Consistent identification of a vertical labiomental branch supplying the lower lip.

Proposal of new mucosal and composite flaps utilizing these arterial branches.

Conclusions:

The deep septal or alar branches of the facial artery can supply upper lip mucosal flaps for lower lip defect reconstruction.
The vertical labiomental branch of the facial artery can supply lower lip composite flaps for upper lip, nose, or lower lip defects.
These proposed flaps offer safe and effective reconstructive options for perioral defects.
