Second Suture
The second suture is a single MN 2–0 suture placed at the level of the thyroid cartilage, approx­imating the distal edges of the platysma muscles, the anterior bellies of the digastric muscles, the perihyoid fascia, and the superficial cervical fascia, thereby assisting in the definition of the cervicofa­cial angle and improvement of the flaccidity in this region (Fig. 5.10).
Third Suture
The third line of sutures is then pl aced, reinforc­ing the previous ones described earlier over the midline with run ning MN 3–0or2–0 sutur es, be- ginning approximately at the level of the thyroid cartilage up to the supramental region depending on each case. This suture does a vertical and supe­rior traction of the infra- and suprahyoid tissues. This also improves mental ptosis (Fig. 5.11 and
Fig. 5.12).
This line of sutures repositions the supra- and in­frahyoid regions and deep tissues in the midline re­positioning the submandibular glands. In patients who still present a herniation of the submandibular glands, we perform a plication at this level. By extending above the mentum, these sutures also

5.3.6 Treatment of the Lateral Cervical Region (V5)
It is impor tant to note that some pat ients only need the vector 6 corrected. However, in order to obtain a better result overall, vectors 4 and 5 also need to be addressed. The dissection is contin­ued onto the face through a classic or reduced retroauricular incision, which facilitates the sub ­cutaneous dissecti on of the lateral and posterior parts of the neck. Underm ining is continued in the midline through the submental incision made previously in order to join both dissec­tions, permitting better redistribution of any ex­cess skin.
AMN2–0 suture is used to plicate the lateral platysma approximately 1.5 cm inferior to the mandibular line and the corresponding earlobe, fixating it to the periosteum of the mastoid follow­ing a posterior oblique vector. This further defines the cervicomandibular angle (Fig. 5.15).
The lateral platysma is then plicated parallel to the anterior border of the sternocleidomastoid muscle with MN 2–0 sutures, in continuation with the previous suture placed in the periosteum of the mastoid. In the majority of our cases, we also treat the anterolateral middle third of the face (V4)

Abstract
This chapter will highlight several important fac­tors the surgeon must keep in mind when per­forming a neck lift. While a brief history of the evolution of face and neck lifting will be discussed, the chapter primarily focuses on the anatomical layers of the neck, with emphasis on the course of the facial nerve, and how these layers can be ap­proached safely and individually in order to opti­mally improve neck aesthetics. The chapter further expands upon the preferred techniques utilized by these authors and also touches upon the important pitfalls and complications that can lead the sur­geon wayward during a surgical neck lift. We have also added a video demonstration that highlights our technique of establishing the most common location of the great auricular nerves emergence from the deep fascia of the neck where it is likely to be injured. Included are figures showing the various degrees of soft-tissue laxity of the neck and the techniques employed to confront each of them. Finally, given that the senior author of this chapter is a world-renowned aesthetic surgeon of the face and neck, we found it fitting to conclude the chapter with expert commentary on how the surgical approach to the neck has evolved over time. In writing this book chapter, we t ruly hoped to impart some wisdom for both novice and expert surgeons for this alluring and delicate surgery, and in the process, learned much about our own tech­niques and results.

Key Points
Thorough knowledge of the lower face, neck anatomy, and retaining ligaments is critical to a fundamental understanding of how to reshape the neck with a surgical approach.
Surgical rejuvenation of the neck can be tre­mendously successful in reshaping not only the aesthetic contour of the neck but also the cervi­comental region as a whole.
Success depends on thorough and methodical evaluation that allows optimal patient selection
and the best chance of a pleasing aesthetic re­sult: this includes comorbid medical conditions that often accompany this age group.
Surgical neck rejuvenation must be done from an oblique and anterior approach to optimize the vectors of soft-tissue tightening.
Common mistakes with surgical neck rejuvena­tion begin with a poor assessment of the etiol­ogy of poor neck appearance: skin and subcutis excess versus platysmal banding versus subpla­tysmal fat excess or some combination of the aforementioned. Failing to adequately treat gland hypertrophy and erroneous vector of pull on the soft tissue that may compromise the final aesthetic appearance of the neck and cervico­mental angle are also common pitfalls for the novice facial aesthetic surgeon.
Case-based examples with media supplements and expert commentary complete this chapter.
6.1 Surgical Anatomy of the Lower Face and Neck
Face and neck lift has changed tremendously in the last century. Nearly 100 years ago, facial laxity was treated with simple posterolateral skin excision and suture closurewith only short-term success. The modern-day face and neck lift has become an amalgamation of decades of surgical advancement, trial and error, and the addition of minimally inva­sive techniques such as lipofilling. Today, most pa­tients with concerns of soft-tissue laxity and aged appearance of the face will arrive at their appoint­ment with excellent background knowledge of the available surgical and nonsurgical techniques to treat this concern. However, few of these patients understand the dynamic interplay between the face and neck. To achieve maximum aesthetic success, both the face and neck must be treated as one con­tiguous unit. This principle must be communicated to the patient during initial evaluation and surgical planning. The reverse is also true: Patients with principle aesthetic complaints regarding the neck should also be evaluated for possible rejuvenation of the face that will allow an elegantly blended transition from the neck to the lower face and beyond.

6.2 Anatomy
Prior to surgical intervention, it is imperative that the plastic surgeon thoroughly understand the anatomy of the superficial and deep planes of the face and cervical region. One will quickly realize that throughout the face and neck there is a fibrous network of collagen that connects underlying fat and soft tissue to overlying skin and dermis. This reticular cutis creates a unique network of stringy tetherings connecting deep tissue to superficial tis­sue. However, there are certain regions of the mid­face, lower face, and neck where these fibrous strings coalesce into ribbonlike structures that may run in transverse, oblique, or longitudinal fashions. These ligamentous attachments connect superficial layers of the face and neck to deep bony platforms or fascial planes in the cervicofacial region. Accom­panying these ligaments are nerves and vertical perforating vessels that can make division of these ligaments tedious and, at times, sanguineous. The goal of the introductory portion of this chapter will be to review the comprehensive ligamentous net­work in the neck and lower face to help the surgeon become familiar with this complex anatomy. Inti­mate knowledge of these fibrous networks will assist the surgeon in evaluating the present-day face and neck lift patient and carry out the appropriate surgical maneuvers to optimally correct soft-tissue ptosis of the neck.
It is well known that the human body has con­centric layers from superficial to deep that, despite our contour irregularities, persist in all directions. This is no dierent for the cervicofacial region. There is a delicate layering from superficial to deep in the face and neck that starts with skin. This is followed by subcutaneous tissue, then the superficial muscu­loaponeurosis incorporating the muscles of facial ex­pression and platysma inferiorly. Then, a deep fascial system and its associated deep muscle group lies over the final laye r, the bony platform. To review, the superficial musculoaponeurotic system (SMAS) is a defined aponeurotic layer laterally. It blends seam­lessly with the t emporoparietal fascia superolaterally over the temporalis muscle and is in continuity with the frontalis muscle superomedially. The SMAS be­comes quite thin when advancing from lateral to medial where it covers the orbicularis oculi. In the lower face, the SMAS is more muscular and is in con­tinuity with the platysmal extensions emanating from the neck. branches of the facial nerve laterally, accidental or

purposeful invasion of the SMAS is allowed as the parotideomasseteric fascia provides a protective barrier between the surgeon and these important neural structures. However, medial to parotid exten­sions, it is imperative that the surgeon respect the anatomy from superficial to deep in order to avoid denervation of critical facial nerve branches. Remaining in a subcutaneous plane is always safe with respect to facial nerve branches. SMAS plica­tion or SMAS resection is also safe when performed distal to the anterior border of the parotid gland where fixed SMAS can be approximated to loose distal SMAS. Here, muscles of facial expression are under a well-defined SMAS layer and are also inner­vated on their deep surface. The frontal branch is just above the periosteum of the zygomatic arch deep to the parotid masseteric fascia. Thus, it is safe to delicately lift a SMAS-only layer or plicate it. Medial to the temporal extension of the zygomatic arch, the surgeon begins to drift into extremely superficial muscles of facial expression such as the orbicularis oculi where accidental SMAS injury, muscle injury, and thus facial nerve zygomatic branch injury are more plausible with potential

6.3 Retaining Ligaments
It is imperative to clarify the retaining ligament anatomy throughout the lower face and neck in order to obtain excellent surgical neck lift results. As stated earlier, there are predictable patterns of fibrous attachments between deep and superficial tissues in the face and neck. These are zones of fixationwhere gravity and soft-tissue atrophy are unable to have an impact. Instead, these factors will aect the soft tissue surrounding these zones and will cause skin and subcutaneous tissue to droop over these fixed points, creating hollows and mounds as opposed to a smooth contiguous surface characteristic of the youthful face. Not only knowledge of these fibrous ribbons heralds impor­tant landmarks for facial nerve branches but also their adequate release is necessary to allow mobi­lization of the soft tissue in the face and neck distal to the ligamentous attachments in the appropriate

We will begin by describing the retaining liga­ments of the lower face. Facelift flaps have been elevated in the standard fashion beginning in the pretemporal hairline, advancing inferiorly in the preauricular crease, around the lobule, and finally
