Differences Between Prosthesis and Hyaluronic Acid

What is Prosthesis?

A prosthesis is an artificial object made of silicone, inserted into areas like the nose, chin, or forehead to add volume. It does not dissolve, so it lasts semi-permanently. The procedure involves making an incision in the skin and inserting the prosthesis in the appropriate area.

What is Hyaluronic Acid?

Hyaluronic acid is an artificial substance used to add volume to areas such as the cheeks, nose, or forehead. It dissolves over time, so it requires regular injections. The procedure involves injecting the substance into the desired area using a needle.

Procedure Methods and Surgery Process

For prosthesis surgery, general anesthesia (sleeping anesthesia) is usually administered, along with local anesthesia. The skin is cut, and the prosthesis is inserted after opening up the skin to the periosteum (the membrane around the bones). Afterward, the area is fixed for a few days.

Hyaluronic acid is typically administered without anesthesia. After cleansing the face, the substance is injected with a needle, and the patient can resume normal activities afterward.

Benefits and Drawbacks of Prosthesis

Benefits of Prosthesis

Since prosthesis lasts semi-permanently, it doesn't need to be reinserted frequently. It is also suitable for creating a defined height, such as in the nose, because it remains firm and does not spread.

Drawbacks of Prosthesis

As you age, the bone structure may shrink, causing the prosthesis to appear raised. In such cases, a revision surgery may be necessary. If complications like infection occur, the prosthesis will need to be physically removed. Having a foreign object in the body for an extended period can cause reactions such as foreign body granulomas.

Post-Surgery Troubles and Solutions

You will likely be advised to keep the area fixed for a certain period, so please follow those instructions. To avoid infection, handle the area with care and keep it clean. If the prosthesis becomes visible under the skin, immediately visit a cosmetic surgery clinic.

Benefits and Drawbacks of Hyaluronic Acid

Benefits of Hyaluronic Acid

Since it only requires an injection, the procedure is quick and easy. There is a dissolving agent called hyaluronidase, which makes it easier to address complications. The substance can be added gradually, allowing you to adjust and check the result as you go.

Drawbacks of Hyaluronic Acid

Over time, it dissolves, requiring re-injection. If relatively soft formulations are used, such as for the nose, they may spread and not give a neat finish.

Risks and Side Effects of Injections

There are risks of infection, allergies, and blood circulation problems. If no improvement is seen over time, it may be necessary to dissolve the substance.

Post-Surgery Recovery and Downtime

Prosthesis Recovery

The area will be fixed for a few days, during which time you cannot wash your face. Swelling and bruising will be most noticeable for the first week. After about a month, swelling will subside, and the final shape will start to appear. Complete results are usually visible after 3 to 6 months.

Hyaluronic Acid Recovery

There may be swelling for 2–3 days, with the degree of swelling varying from person to person. You can wash your face immediately after the procedure and apply makeup the next day. The final result typically appears in about 2 weeks.

Managing Swelling and Pain After Surgery

For swelling and pain, pain relievers can be taken for symptom relief. If severe pain persists, there may be a significant side effect, so contact your doctor.
