RESUMO

BACKGROUND: Despite the central role of the platysma in face and neck rejuvenation, much confusion exists regarding its surgical anatomy. OBJECTIVES: This study was undertaken to clarify the regional anatomy of the platysma and its innervation pattern and to explain clinical phenomena, such as the origin of platysmal bands and their recurrence, and the etiology of lower lip dysfunction after neck lift procedures. METHODS: Fifty-five cadaver heads were studied (16 embalmed, 39 fresh, mean age 75 years). Following preliminary dissections and macro-sectioning, a series of standardized layered dissections were performed, complemented by histology and sheet plastination. RESULTS: In addition to its origin and insertion, the platysma is attached to the skin and deep fascia across its entire superficial and deep surfaces. This composite system explains the age-related formation of static platysmal bands, recurrent platysmal bands after complete platysma transection, and recurrent anterior neck laxity after no-release lifting. The facial part of the platysma is primarily innervated by the marginal mandibular branch of the facial nerve, whereas the submandibular platysma is innervated by the "first" cervical branches, which terminate at the mandibular origin of the depressor labii inferioris. This pattern has implications for postoperative dysfunction of the lower lip, including pseudoparalysis, and potential targeted surgical denervation. CONCLUSIONS: This anatomical study, comprised of layered dissections, large histology, and sheet plastination, fully describes the anatomy of the platysma including its bony, fascial, and dermal attachments, as well as its segmental innervation including its nerve danger zones. It provides a sound anatomical basis for the further development of surgical techniques to rejuvenate the neck with prevention of recurrent platysmal banding.

RESUMO

The author has modified previously described techniques of the superior suspension of the platysma muscle to Lore's fascia by developing an auriculoplastysmal fascial flap, which detaches the posterior platysma from its retaining ligaments to the sternomastoid muscle. Anterior to this flap, the platysma muscle is undermined and suture captured with three throws of a permanent 2.0 Tevdek suture. This suture and its three throws are fixed anterior to the tragus, which includes Lore's fascia and on tightening elevates the whole of the anterior neck as well as defines the cervicomental angle. A separate submental dissection may be required to assess and deal with pathology and resect excessive laxity of the platysma which has not been adequately addressed by the lateral superior traction suturing technique. Follow-up of fifteen cases of secondary facelift surgery with recurrent neck laxity demonstrated the fate of the suturing to Lore's fascia. The permanent knot at the pre-tragal fixation point descended approximately 3 cm from the original position at the pre-tragal region. Secondary surgery is facilitated by capture of the knot and re-suturing it to its original primary position, restoring the neck to the approximate pre-operative condition and avoiding excessive dissection including return to the submental incision.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

RESUMO

The Australian population is 10% of Asian origin, and many of our Asian patients have had nasal augmentation using prosthetic material prior to immigration or as medical tourists back in their country of origin. Insertion of nasal prostheses is the most common way to augment the nasal dorsum in the Asian patient and although there is a trend towards autogenous primary augmentation still, the vast majority of patients seen in clinical practice have had augmentation by the insertion of foreign material generally silicone.

RESUMO

Over a 5-year period, my technique of approaching and modifying the aging neck has changed from direct suturing of the medial platysma bands and strong posterior traction of the platysma to superior elevation of the posterior platysma and strong fixation to the tympanoparotid fascia. When indicated, redundant anterior platysmal bands are resected instead of approximated. Evaluation of these anterior bands preoperatively for thickness and degree of descent allows more precise decision-making regarding the need to resect redundant and excessively thick or long anterior platysmal bands. The added advantage of the strong fixation of the platysma in a vertical fashion to Loré's fascia (the tympanoparotid fascia) leads not only to an improvement in the contour of the jawline and submental area but also to the undervalued aesthetic feature of a defined contour and visually increased length of the sternomastoid muscle.

RESUMO

Thermage is a nonsurgical treatment for sagging skin in the jowl, neck, and eyelids. Abdominal striae, loose upper arm skin and buttock sagging, and improvement of the appearance of cellulite have become amenable to the radiofrequency treatment. Radiofrequency passed through cooled epidermis allows for radiofrequency-induced thermal damage to the dermis and deep dermal collagen (fibrous septae). The remodeling of the collagen leads to clinically discernible improvement in the sagging skin and skin quality; the remodeling of deep dermal collagen (fibrous septae) allows modeling of contours and improvement of the cellulite appearance.

RESUMO

Nasal augmentation is a highly popular technique used among Asian patients to change the characteristic flat Asian nose to a more prominent nose. The extent of augmentation is determined by the aesthetic desires of the patient, and the method of augmentation is provided by the surgeon, who takes into account the technical limitations of his or her preferred technique and the proposed surgical result. Although a silicone prosthesis is the most common implant used to improve the nasal appearance, the author prefers an autogenous approach with the olecranon bone used as a dorsal implant and conchal cartilages used to improve nasal tip projection because of the long-term stable results. A series of 31 cases over 15 years is reviewed. The technique varies little from that described for saddle nose by Hodgkinson in 1992 [5]. The procedure is a variation of the ulnar donor site originally described by Antia et al. [1].
