What are the Points to Consider and Complication Management in Cosmetic Applications for the Hand?

1. Methods Used
Hand rejuvenation applications have been increasingly gaining interest in the field of aesthetic dermatology and plastic surgery in recent years. The signs of aging that emerge over time are observed as volume loss on the dorsum of the hands, decreased skin elasticity, increased visibility of veins and increased pigmentation. Different invasive and non-invasive treatment options are available to eliminate these signs.

Main methods used:

Laser Treatments: Q-switched lasers, ablative and nonablative lasers.

Chemical Peels: Superficial and medium-depth peeling agents.

Light and Energy Based Systems: IPL, photodynamic therapy.

Filling Applications: Hyaluronic acid, poly-L-lactic acid (PLLA), calcium hydroxyapatite (CaHA) and autologous fat grafts.

Each method should be applied within a specific indication, and an individual treatment plan should be created by taking into account patient characteristics and expectations.

2. Anatomical and Technical Considerations
The dorsal skin of the hand is thinner than the face and more sensitive to ultraviolet rays. Therefore, the risk of complications during the healing process is high. In injection applications:

Vein and tendon anatomy should be known in detail.

Ultrasound-guided applications may be preferred, especially in high-risk patients.

Excessive correction and injection near the metacarpophalangeal joint should be avoided.

Homogeneous distribution of the material should be ensured with gentle massage after injection.

3. Dermal Fillers: Complications and Management
3.1. Common Complications
Persistent edema

Sensory impairment (paresthesia, tingling)

Foreign body granuloma

Contour irregularities

3.2. Treatment Options
In Granulomas: Intralesional steroids, topical steroids, allopurinol, minocycline, 5-FU combinations.

Antibiotic Protocol: 7-day treatment with at least two antibiotics (e.g. cephalosporin + macrolide).

In Hyaluronic Acid Fillers: Hyaluronidase injection is effective as first-line treatment.

In CaHA-Containing Fillers: Steroids have limited effectiveness, surgical excision is the first choice if there is a granuloma.

4. Autologous Fat Graft: Application and Complications
4.1. Technical Features
Multiple injections should be preferred in small volumes.

Vascular injuries are reduced by using blunt-tipped cannulas.

Grafts are spread peripherally for revascularization of fat cells.

Excessive pressure should be avoided in the recipient area during injection.

4.2. Complications
Transient edema and bruising

Infection, cyst formation

Fat necrosis, dysesthesia

Repeated injections required due to resorption rates (up to 24%)

4.3. Preventive Measures
Hands should be kept elevated for the first 2 days after surgery, heavy use should be avoided for 1 week.

A foam pad applied to the dorsal area reduces edema and ecchymosis, and prevents graft migration.

5. Hyaluronic Acid Fillers: Specific Methods and Risks
5.1. Technical Approach
To avoid intravascular injection: retrograde threading or fan technique is recommended.

Injection onto tendons and bones should be avoided.

After injection, the material should be distributed parallel to the extensor tendons.

5.2. Application Methods
Multiple bolus (most common)

Single bolus

Cannula applications

5.3. Complications and Management
The number of entries should be reduced to reduce the risk of bruising.

Most complications can be managed with hyaluronidase.

Excessive filler injection can increase shadowing and vascular appearance.

6. Conclusion and Clinical Recommendations
Hand rejuvenation applications can be quite successful and patient satisfaction can be high with appropriate technique, product selection and complication management knowledge. However:

Individual assessment should be made for each patient,

Anatomical knowledge should be mastered,

Information about possible complications of the material used should be acquired.

A detailed history, correct injection techniques and a prepared approach against complications are indispensable for safe applications.
