Introduction

Hematomas are one of the most frequently reported complications in aesthetic surgery. They can range in size and may present with a variety of nonspecific signs and symptoms. While smaller hematomas may resolve without incident, larger hematomas, if left untreated, can have untoward consequences for the patient including pain, poor cosmetic outcome, scarring, as well as skin and tissue ischemia leading to necrosis and infection.

Hematomas are one of the most frequently reported complications in aesthetic surgery

Hematoma is a relatively common complication following rhytidectomy, which is one of the best studied aesthetic procedures with regards to hematoma rates. The reports on incidence range between approximately 0% and 14% [1,2,3,4]. This complication can lead to devastating sequelae such as flap loss, airway compromise, infection, hyperpigmentation, increased recovery time, and a poor aesthetic result.

Risk factors predisposing to postoperative bleeding and hematoma formation have been previously identified and include demographic factors such as gender and smoking status, medical co-morbidities such as hypertension and malignancy, anticoagulant medications, surgical and anesthetic techniques, as well as postoperative management [5].

A hemostatic net applied to all areas of skin elevation closes the dead space

In an effort to impact the incidence of hematoma formation following facelift, Auersvald and Auersvald developed a novel technique to essentially eliminate hematoma formation in the early high-risk post-operative period. The application of a hemostatic net to all areas of skin elevation closes the dead space, negating the potential of expansive bleeding [6].

Concept

In 1998 Baroudi and Ferreira introduced the concept of internal quilting sutures in abdominoplasty to close the detached space in order to dramatically decrease the incidence of seroma [7]. Building on Baroudi’s contribution, Pollock and Pollock described their experience utilizing progressive tension sutures in abdominoplasty procedures to not only eliminate dead space, but also securely advance the flap with incremental tension transferred from the skin closure incision to the superficial fascial system [8]. This concept of progressive subcutaneous sutures was then applied to facelift in order to achieve secure flap position, close the dead space, and improve the overall aesthetic outcome [9]. Due to the difficulty in precisely and completely covering the entire facelift flap, the internal quilting sutures in face- and necklifts were not widely adopted. Building on these concepts, Auersvald and Auersvald applied the principles of mechanical closure to their facelifting procedures, formulating the technique of transcutaneous continuous transfixing sutures of the skin flaps to the deep tissues and creating a hemostatic net [6].

Technique

The hemostatic net is applied after completion of the facelift procedure when the subcutaneous flaps have been tailored and inset. The borders of the subcutaneous dissection are marked as the boundaries for the application of the net. The net is created with continuous sutures that focus on closing the dead space between the skin of the face and neck with the corresponding deeper tissues of the superficial muscular aponeurotic system (SMAS) in the face and platysma in the neck. The net is accomplished utilizing a Mononylon 5‑0 suture with a triangular needle of at least 20 mm in length.

After marking the boundaries of the dissection and inset of the flaps, the head and neck are slighted extended and turned away from the side being addressed. The assistant will apply gentle pressure and traction to the flaps to ensure optimal skin redraping (Fig. 1). The first line of the net is initiated at the midline of the dissected neck at the position just below the newly created cervicomental angle (Fig. 2). The needle passage follows a uniform pattern entering perpendicular to the skin, then plunging into the platysma at 45 degrees and emerging at the same distance of 1 cm from the point of entry (Fig. 3). This spacing and mild traction on the suture by the assistant ensures that the suture will not be loose but also not too tense, thus preventing impairment to blood circulation. The SMAS-platysma is encompassed at each passage of the needle so as to bring it into contact with the skin, thereby closing the dead space (Fig. 4). The first line of suture ends in the most posterior portion of the retroauricular incision (Fig. 5). The second line begins approximately 1 cm below, following parallel to the first and continues with additional rows until all the dissected areas are covered by the hemostatic net (Fig. 6).

All of the patients shown here were operated on as outpatients and discharged the same day from the surgical unit. The net was removed 48–72 h post-operatively.

Removal was accomplished after cleaning the skin where the net was applied thoroughly with an alcohol solution to remove all dried blood. After ensuring the sutures were free of debris, the net was removed as with any simple suture by first cutting all knots, then cutting each loop and removing each single strand of suture.

Results

Over a 10-month period the first author (TGOD) used the hemostatic net on 66 of 108 patients undergoing face- and/or necklift procedures. The other patients were treated with Tisseel, a fibrin sealant, and drains. Patients with Fitzpatrick skin type 1–5 were treated with the net. There were no hematomas in either group during this period. There was one small seroma in a patient treated with the net, which was successfully treated with aspiration and re-application of the net over the area for 48 h. There were no incidences of flap necrosis or flap loss. One patient had concerns about the hyperemic appearance of the suture marks at 2 weeks post-operatively, which was successfully and quickly resolved with a single pulsed-dye laser treatment. There was no incidence of post-inflammatory hyperpigmentation from the suture tracks.

A review of the charts identified the indications for application of the net. Indications included patients with poorly controlled hypertension as identified by blood pressure trends during the procedure, all male patients, patients deemed likely to be less compliant in the post-operative period, patients with extreme laxity of neck skin, and all patients undergoing procedures on Fridays.

The net also improved skin redraping in cases of excessive, poor quality cervical skin

The first patient in whom the authors initiated use of the hemostatic net was a 68-year-old female that had undergone outpatient face- and necklift including deep cervical surgery with management of deep fat, digastric muscles, and submandibular gland reduction. She presented to the surgical center 24 h post-operatively with an expanding hematoma in her face and neck. In addition, she exhibited hypertension that was refractory to multiple hypertensive medications (Fig. 7). The hematoma was evacuated in the operating room utilizing dexmedetomidine IV sedation, which ultimately lowered the blood pressure. Faced with the risk for recurrent bleeding on discharge, the hemostatic net was applied after complete evacuation of the hematoma (Fig. 8). The net was removed at 48 h (Figs. 9 and 10).

In addition to eliminating the risk of hematoma in the early post-operative period, the authors found, as reported by Auersvald, that the net improved skin redraping in cases of excessive, poor quality cervical skin. Fig. 11 shows the pre-operative case of an 80-year-old man with severe skin laxity. This patient had risk factors for hematoma including hypertension and male gender with the complicating co-morbidity of Parkinson’s disease. He was treated with facelift with extensive subcutaneous cervical dissection and deep central neck surgery. His post-operative recovery was uneventful and he resumed normal activities at 2 weeks post-operatively (Figs. 111213 and 14).

Discussion

The occurrence of hematoma is a dreaded complication of all aesthetic procedures. In facelift surgery the occurrence of hematoma may lead to a more difficult post-operative recovery with prolonged edema and can compromise the final outcome by creating subsequent fibrosis and irregularities in the subcutaneous plane. Expanding hematomas that are delayed in diagnosis and treatment can result in catastrophic sequelae including flap ischemia and tissue loss leading to disfiguring scars and, in the worst-case scenario, life-threatening airway compromise [10, 11].

The occurrence of hematoma is a dreaded complication of all aesthetic procedures

The authors’ initial concerns related to the hemostatic net based on multiple cognitive biases. The authors’ first impression was that the appearance of the net is barbaric and would not be tolerated by the patient. To date, no patients have declined the net based on appearance.

The second concern was that scars would be created by the suture tracts. This was not experienced in the first author’s series and, according to recent communication with AA (December 2018), the second two authors have not had scarring or hyperpigmentation in over 1200 facelifts using the net. The first author has had two patients decline use of the net for fear of tract marks despite communicating to them the extremely low risk.

The third concern related to tissue perfusion. The impression was that the sutures may compromise perfusion to the facelift flaps, leading to skin necrosis. There were no episodes of compromised perfusion or tissue loss in the first author’s series. This is consistent with the reports of Auersvald and Auersvald [4, 6]. In addition, Dr. Jared Little of the University of Louisville recently utilized intra-operative laser angiography using the SPY System (LifeCell Corp., Branchburg, NJ, USA) for the assessment of perfusion in large cervicofacial flaps used for post-melanoma resection defect reconstruction (Figs. 15 and 16). The SPY was used to measure baseline flap perfusion after inset of the cervicofacial flap and showed 89% perfusion. The post-net application of SPY measured 85% perfusion (Fig. 17). The flap healed without event and the patient had a very satisfactory outcome (Fig. 18).

The final concern was related to the length of time it would take to apply the hemostatic net. The time required directly related to the amount of subcutaneous undermining. It was found that the time required ranged from 15 min to 35 min. When compared to the potential complications from hematoma, the authors found this time was worth the reduction in risk. The resources required and strain placed on the surgical staff and faculty when hematomas occur after hours and over the weekend have been negated. In addition, the authors have gained increased confidence in their ability to redrape the skin in the most advantageous position in cases of severe skin laxity. They have confidently raised cervical flaps extending to the clavicle to accomplish redistribution of skin without fear of hematoma in the lower neck where vascularity is considerable.

Practical conclusion

  • The addition of the hemostatic net to the authors’ facelift practice has proven to be a safe and effective method to prevent hematoma in the early post-operative period.

  • The net enhances the authors’ ability to accommodate severely lax cervicofacial skin by precise positioning of the flaps over the sculpted shape of the face created with the facelift procedure.
