Abstract
Background:
To describe a novel technique to modify the proportional length of the anterior-to-posterior digastric muscles to improve neck aesthetics.
Objective:
To provide an objective measure to quantify neck rejuvenation and a novel technique to adjust the digastric ratio.
Design:
We retrospectively compared 52 patients who had neck rejuvenation with or without digastric manipulation. Preoperative and postoperative images were analyzed and compared with computer software using a novel analysis technique to measure the digastric ratio and neck height. Distances between the menton, cervical point (CP), and gonion were measured.
Results:
The anterior-to-posterior digastric ratio improved an average of 26.5% (p < 0.01) in the new technique group, 15.9% in the control group. Distance of the CP to the inferior edge of the mandible decreased an average of 13.9% using the new technique.
Conclusion:
The ratio of anterior-to-posterior digastric muscle appears to improve as well as the neck height with manipulation of the digastric muscles.
