Description

FIELD OF THE INVENTION

The invention relates to the field of neck lift surgery. More specifically, the present invention relates to surgical application systems for a neck lift and methods of insertion thereof.

BACKGROUND OF THE INVENTION

In plastic surgery, a neck lift, or lower rhytidectomy, is a surgical procedure that improves visible signs of aging in the jawline and neck. A neck lift may remove excess fat and skin in the lower face that creates jowls, remove fatty deposits under the chin, tighten loose neck skin, adjust muscle banding in the neck, for example that create abnormal contours, and/or the like. Factors that cause the need for a neck lift may include heredity, gravity, environmental conditions, stress, and/or the like. These factors may cause excess wrinkling of the neck skin, such as referred to colloquially as “turkey wattle” or a double chin, and impair jowl lines.

Other procedures related to lower rhytidectomy are cervicoplasty and platysmaplasty, which are correction of submental ptosis sometimes necessary to reverse the effects of aging. Cervicoplasty and platysmaplasty may be performed together with facial rhytidectomy, when surgeons may need to address the cervical region.

Originating from the pectoralis major muscle fascia, the platysma is a layer of muscle that has multiple insertions. Moving anterior to posterior, the muscle is anchored to the mentum and the inferior mandibular border and meets the orbicularis oris laterally and then the depressor anguli oris. Platysmal meshing with the depressor anguli oris contributes to the superficial muscular aponeurotic system (SMAS), highlighting its importance when attempting to reverse facial aging.

A neck lift may be performed by a horizontal submental incision for lipectomy, with excision or plication of hypertrophic anterior platysmal bands, and wide subcutaneous cervical dissection. This may correct fasciocutaneous ligaments extending from the dermis to the facial fascia, and osseocutaneous ligaments extend from the dermis to the periosteum.

Adipose tissue may comprise subcutaneous and subplatysmal fat tissue. Increased amounts of subcutaneous fat may be observed with weight gain, aging, lipodystrophies, and the like. Subplatysmal fat is far more vascular and fibrous than subcutaneous fat and is visualized after incising the platysma muscle. This difference may result in reduced efficacy of liposuction of subplatysmal fat.

Accordingly, there is a need for a simple and accurate way for the insertion of a neck lift sling, that will ensure satisfactory results of the neck lift surgery.

Reference is now made to FIG. 3 which is a flowchart of a method for inserting a sling in neck lift surgery according to some embodiments of the invention.

In step 310, incisions may be made near each ear of a patient along a posterior edge of the tragus down through the lobule and posteriorly at the retroauricular sulcus through the hairline, and near a chin of the patient parallel to the mental crease line and five millimeters posterior to the crease line, wherein the incision cut near the chin has a length of 4 centimeters, as illustrated in FIGS. 4A and 4B. In some embodiments, prior to making the incisions, the patient may be anesthetized and positioned supine on a surgical table. For example, the procedure may be done under local anesthesia, sedation or general anesthesia.

Reference is now made to FIGS. 4A and 4B, which are schematic illustration of views of incisions for neck lift sling surgery, according to some embodiments of the invention. The posterior edge of the tragus 702 may be marked down through the lobule and posteriorly at the retroauricular sulcus through the hairline. Mental crease line 701 may be marked five millimeters posterior to the crease, for a length of 4 centimeters. In some embodiments, the markings may be located at various locations and of various sizes according to ease of attachment, to the particular anatomy of a subject, for a particular method of attachment, for a particular configuration of components, for a particular shape of sling, and/or the like. For example, the markings may be located between 1 and 25 millimeters posterior to the mental crease for a length of between 1 and 10 centimeters.

In some embodiments, the incisions may be cut in the mental crease, then on the distal half of the retroauricular sulcus. In cases of excessive skin redundancy, the incision may be cut preauricularly to the lobule and the edge of the tragus.

In step 320, a subcutaneous pocket may be created, by local infiltration and undermining is performed. Local infiltration to the subcutaneous plane may be with NaCl 0.9% 100 cc, epinephrine 1:300,000, and local anesthetics when the procedure is done under local anesthesia. Undermining of the skin may be performed using Gorney scissors in a subcutaneous plane. Most of the dissection may be accomplished by spreading maneuvers of the scissors. The undermining may be performed from the three mentioned incisions: one mental and two retroauricular. In the mental incision, dissection may be performed also anteriorly to the chin for correction of ptosis and creation of space for the edge of slings 100-500.

In some embodiments, after the subcutaneous plane is created, meticulous hemostasis is done under direct vision. Pockets are packed with soaked gauzes, one from each incision, with povidine iodine and surgical application system 10 packaging is opened and system 10 is prepared for insertion.

In step 330, surgical application system 10 is inserted to said subcutaneous pocket. In some embodiments, gauzes are removed and the subcutaneous pocket is exposed from the mental incision using a retractor. In some embodiments, surgical application system 10 is inserted such that lateral edges 54 and 55 of applicator 50 are exposed via incisions 702 near each ear of a patient. After the insertion slings 100-500 are still spread on and supported by applicator frame 50 inside the subcutaneous pocket.

In some embodiments, when system 10 comprises delivery tube 60, the delivery tube may be slightly pulled from said subcutaneous pocket, from one of the incisions, leaving the applicator and the sling inside said subcutaneous pocket, in optional step 335. Delivery tube 60 may compress application 50 and sling 100 to ease the insertion of system 100. After the pulling of delivery tube 60, as illustrated in FIG. 4C, application 50 and sling 100 are left inside the pocket.

In step 340, farm 51 may be detached from slings 100-500 and then slightly be pulled from the subcutaneous pocket, as illustrated in FIGS. 5Am5B and 5C. Trade 20 anchoring slings 100-500 to frame 50 may be cut via incision 702. Frame 51 may slightly be pulled from one incision 702 while lock 58 is being held, as illustrated in FIGS. 5A and 5B. In some embodiments, tread 25 anchoring slings 100-500 to lock 58 is cut via the other incision 702, as illustrated in FIG. 5C. In some embodiments, the outcome is a neck lift sling which is easily and precisely located at the subcutaneous pocket.

In step 350, the ends of two extensions of the sling may be anchored near the subcutaneous connective tissue near the ear, and a front edge of the sling to the subcutaneous tissue near the chin. In some embodiments, ends 104-504 and 105-505 may be anchored near the subcutaneous connective tissue near the ear near incision 702 and front edges 106-506 of the sling to the subcutaneous tissue near the chin at incision 701.

In some embodiments, the method may further include closing the incisions, for example, in two layers, and drains inserted from the retroauricular incisions for the first 24 hours. Dressings may be performed with an antibiotic ointment and gauzes, and a soft collar bandage may be worn. Antibiotics may be prescribed for the first 7 days, such as 1-gram cephalexin three times per day. Local treatment may be performed with an antibiotic ointment. Patient may be allowed to shower after the first 24 hours, and may be abstain from physical exercise on the first 4 weeks. Sutures are removed on postoperative day 7. The soft collar bandage.
