From: A Comparative Study of Surgical Techniques on the Cervicomental Angle in Human Cadavers Arch Facial Plast Surg. 2002;4(4): After undermining and submental lipectomy, the anterior bellies of the digastric muscles are plicated. These muscles diverge laterally along a path toward the hyoid bone, permitting the placement of 3 to 5 sutures. Adapted from Caplin and Prendiville. 20 Figure Legend:

From: A Comparative Study of Surgical Techniques on the Cervicomental Angle in Human Cadavers Arch Facial Plast Surg. 2002;4(4): A, A mastoid-to-mastoid suspension suture is placed through the medial edge of the platysma in a horizontal mattress fashion and interlocked with a second suture placed in the same fashion through the contralateral edge of the platysma (inset). These sutures are drawn through a previously formed subcutaneous preplatysmal tunnel and sutured to the mastoid periosteum bilaterally. The face is turned toward the contralateral side when the suture is secured to the mastoid periosteum. Adapted from Caplin and Prendiville. 20 B, Posterior view of a mastoid-to-mastoid suspension suture placed in the left neck of a cadaver. Figure Legend:

Error bars represent SDs. Group A, preauricular and postauricular superficial musculoaponeurotic system (SMAS) plication and midline platysmal plication; Group B, preauricular and postauricular SMAS plication, midline platysmal plication, and suturing of the anterior bellies of the digastrics; Group C, preauricular and postauricular SMAS plication, midline platysmal plication, and interlocking mastoid-to-mastoid preplatysmal sutures; Group D, preauricular and postauricular SMAS plication, midline platysmal plication, suturing of the anterior bellies of the digastrics, and interlocking mastoid-to-mastoid preplatysmal sutures. CM indicates cervicomental; Mentum-CM Distance, the distance between the mentum and the CM angle; and Sternum-CM Distance, the distance between the sternum and the CM angle. Figure Legend:

From: A Comparative Study of Surgical Techniques on the Cervicomental Angle in Human Cadavers Arch Facial Plast Surg. 2002;4(4): A, Lateral view of a cadaver shows an obtuse cervicomental (CM) angle caused by unfavorable anatomic characteristics, including cervical skin laxity, attenuation of the platysma, preplatysmal and subplatysmal fat, and a low hyoid. B, Postoperative lateral view shows that placement of a mastoid-to-mastoid suture has elevated the breakpoint of the CM angle, reducing its magnitude. Figure Legend:
