Hyperbaric oxygen therapy in aesthetic procedures

Hyperbaric oxygen therapy in aesthetic procedures


The desire to stay young or mirror a certain image may bring more harm than good, especially when complications from aesthetic procedures are difficult to avoid. The use of minimally invasive techniques for aging-related conditions and facial corrections have been gaining popularity in recent years. In 2020, the American Society of Plastic Surgeons (ASPS) reported a 13.2 million total cosmetic minimally-invasive cosmetic procedures, 174% increase in minimally-invasive cosmetic procedures since 2000. Soft tissue fillers represent 25.68% of the 13.2 million of these procedures performed in the United States (US) annually.1 Minimally invasive procedures have also become popular recently in the Asian market, influenced by South Korean culture. Asian patients, like those in the United States, prefer non-surgical, minimally invasive treatment options and show concern about retaining a natural appearance.2 In terms of surgery and nonsurgical procedures, South Korea did nearly 6 times more than the global average. In 2011, 130.564 cosmetic procedures per 10.000 people were performed in South Korea, 78.665 of which were nonsurgical such as hyaluronic acid filler and botulinum toxin (popularly referred to as “botox”) injections.3

Hyaluronic acid, placental extract, calcium hydroxylapatite, and poly‐L‐lactic acid are a few examples of commonly used fillers today.4 Dermal fillers are injected into the desired area to augment the skin and create a “revived-skin” look.5 However, administering these fillers poses the risk of complications, including infection and vascular occlusion, which, if left untreated, may progress to tissue necrosis.6

Thread lifting involves a thread with barbs at the proximal end or threads without barbs configured in a mesh-like form being embedded in the fascia. The most common thread used in this procedure is polydioxanone (PDO), considered one of the safest materials as it is absorbed within 6 months.7 Complications such as bruising, swelling, facial asymmetry, and suture extrusion require immediate and effective treatment modalities that prevent further tissue damage and infection.7,8

The cellular inflammatory cascade and wound healing process is triggered by tissue hypoxia. Maintaining an oxygen pressure of at least 30 mmHg in tissues is essential to provide an environment suitable for wound healing. Hyperbaric oxygen therapy (HBOT) is a safe and effective therapeutic option that facilitates the systematic repair of ischemic tissues by direct oxygen diffusion through the inhalation of 100% oxygen in a pressurized chamber. The benefits of HBOT have been reported in cases of post filler necrosis, vascular occlusion, crush injuries, difficult-to-heal ulcers, hand-replantation, and deep skin infections.9 This report further describes the use of HBOT as adjunctive therapy in three cases of complications arising from aesthetic procedures.

Case Presentation

Case 1

A 55-year-old female patient presented with inflammation and redness of the right jaw (Figure 1A). The patient had received filler injections along her left and right jaw lines made from placental extract 2 weeks prior. Three days after the injection, she experienced pain and tenseness in her right jaw that prevented her from fully opening her mouth. No fever was reported. Her social and medical histories were unremarkable. Physical examination revealed an inflamed right buccal region within the salivary gland area with a pus-filled core and an unclear margin. Laboratory results indicated a slightly elevated leukocyte count (12,500 per uL of blood), while the other parameters were within the normal limits. The patient was diagnosed with sialadenitis likely caused by a blockage of the salivary gland or duct from filler injections. Her treatments included daily debridement, IV broad-spectrum antibiotics for 7 days along with 7 consecutive, 90-minute HBOT sessions, once daily at 2.4 ATA (Figure 1B). The wound was clinically evaluated every 3 days. As the days progressed, the inflammation began to reside as the area of infection continued to shrink, leaving a once-blurred, now clear margin around the wound (Figure 1C). The wound fully healed within one year (Figure 1D).

(C) After six HBOT sessions, the area of infection became more localized. (D) A completely healed wound at 1-year post debridement.

Case 2

A 29-year-old female complained of red patches on her cheek and chin area. Two weeks prior to her visit, she received a thread lift procedure using barbed threads along her nasolabial folds and jawlines from an aesthetician at a local beauty clinic (Figure 2A). She experienced itchiness around the implanted area the day after the procedure and began scratching her face. A week later, she noticed an exposed thread on her right cheek and returned to the clinic but received no satisfactory explanation. Consequently, she forcefully pulled the thread out herself. The patient had no remarkable medical or social history. Multiple small wounds with erythema were observed on the nasolabial folds and buccal regions. The laboratory results were unremarkable. We suspected that the patient exhibited a hypersensitivity reaction to the absorbable surgical suture used in the procedure, and this had progressed into a secondary skin infection caused by continuous scratching and the vigorous extraction of the thread from her right cheek. The patient received oral broad-spectrum antibiotics for 7 days, nine 90-minute HBOT sessions at 2.4 ATA three times per week, and antihistamine tablets once daily. After one month, the wound exhibited less inflammation, improved vascularization, and presented a vibrant red color (Figure 2B).

Case 3

A 32-year-old female arrived at our clinic for a consultation regarding a nose implant. In her attempt for a higher nose tip, she had received injections of hyaluronic acid fillers into her nose a few weeks prior at a beauty clinic. Her medical and social histories were unremarkable. Inflammation with blanchable erythema on the nasal tip was evident upon inspection with slight tenderness upon palpation (Figure 3A). The laboratory results were unremarkable. The patient was diagnosed with post-filler vascular occlusion. The implant procedure was canceled due to the risk of infection from both filler and implant being present in the same area. 90 minute-HBOT sessions at 2.4 ATA were administered twice weekly to improve vascularization into the nasal region. One month later, the patient’s nose appeared vibrant red with less discoloration indicating enhanced blood flow to the nasal area (Figure 3B).

Complications from aesthetic facial procedures can be disastrous due to the risk of developing vascular occlusions and skin infections. As such, they require prompt and effective therapy solutions. By utilizing highly pressurized oxygen diffusion to hypoxic tissues to enhance the vascularization of the face and given its bactericidal effects, HBOT serves a beneficial purpose in the wound healing process.

The use of non-invasive facial rejuvenation techniques (eg, fillers) has gained popularity in recent years. Hyaluronic acid is favored among the other types of fillers as it is regarded as the safest, most effective filler for the facial region. Placental extracts are another form of facial filler. A study in Korea examined combinations of human fibroblasts and placental extract as facial augmentation fillers. The study found significant statistically fibroblast proliferation in the treatment group compared with the controls.10 Though being considered safe, the injection of facial fillers still poses risks for its recipients.11 In the Netherlands, the likely under-reported incidence of vascular obstruction from filler injection is 1:6600.12 Some vascular adverse effects are caused by the wrong injection site, excessive filler volume, improper indications, and incorrect injection techniques.5 The most common mechanism of vascular occlusion is an intravascular embolism, which is indicated by pain, blanching, livedo pattern, delayed capillary refill time, blue or greyish discoloration, and coolness of the occluded area.13 Glashofer et al divided the adverse effects of filler injections into two groups: early and delayed. The early effects included bruising, swelling, erythema at the injection site, hypersensitivity, and vascular compromise. The delayed effects included infection, as well as the formation of granulomas and biofilms.14

In recent years, HBOT has been gaining popularity in treating vascular compromise and deep skin infections due to its hyperoxygenation effect.15 Hyperoxygenation triggers local cell metabolism and promotes recovery of cellular function thereby increasing fibroblast proliferation, microvascular repair, and capillary angiogenesis. The release of reactive oxygen species (ROS) and vascular endothelial growth factor (VEGF) plays a significant role in this case.16 These help to improve microcirculation, promote wound healing, and control infections.17 Therefore, HBOT has been used as an adjunctive therapy option in several cases of vascular occlusion due to filler injections.11,14,18

In cases 1 and 3, HBOT was administered along with antibiotics to ease the infection of the parotid gland and the surrounding skin for patient 1 and to aid the vascularization of ischemic tissue on the nose of patient 3. Several studies on the body’s reaction to filler injections have been published. One case of dermal filler on the buccal region had a delayed onset and diffused swelling that occurred years after the procedure, triggered by a periodontal surgery.19 Another delayed case of dermal fillers was the manifestation of a small parotid mass followed by an eyebrow mass two months after the parotidectomy.20 Therefore, it is quite common for the salivary gland to be affected during this procedure. HBOT has proven effective in treating multiple cases of filler rhinoplasty21 and tissue necrosis.22 Unfortunately, to date, there is no protocol for how many sessions needed to treat infections. Therefore, the number of HBOT sessions is determined upon clinical evaluation by the physician.

Another method of facial rejuvenation is thread lifting, which has garnered attention in recent years due to being minimally invasive with results lasting up to 5 years after the procedure.7 Polydioxanone (PDO) threads are commonly used in this procedure and are absorbed by the body over a 4 to 6-month period. Many complications arise from this technique including thread exposure, dimpling, parotid gland injury, inflammation, and facial asymmetry. Anh et al reported a case of multiple palpable masses on the cheeks after 3 courses of acupoint embedding therapy (AET) with PDO over 2 years.23 Wang presented two cases of thread lifting complications (thread extrusion, skin dimpling).24 Patient 2 received HBOT sessions to reduce the inflammation from an allergic reaction and restore the tissues injured by the implanted barbed thread.

The recommended treatments for vascular compromise include firmly massaging the affected area, warm compression, aspirin, hyaluronidase injection and, specifically post hyaluronic acid injection, antibiotics and HBOT as an added treatment option.13 HBOT is utilized as an adjunctive treatment to facilitate tissue repair. Given its anti-inflammatory and anti-bacterial effects, HBOT is an effective means of treating complications arising from aesthetic procedures. Follow-up visits are necessary to ensure the effectiveness of the treatment provided. The number of visits depends on the clinical evaluation of the affected area during the patient’s last visit.


The effects of HBOT in combination with antibiotics, anti-inflammatory and antihistamine agents in managing complications from minimally invasive aesthetic procedures are favorable. HBOT is a supplemental therapy that effectively delivers oxygen systemically to maintain tissue viability during such complications.
