　Sebaceous gland cyst (commonly known as "pinoma")

　★ Source: Cyst formed due to obstruction of sebaceous gland duct and accumulation of secretions in the gland. It is more common in young people with strong sebaceous gland secretion.

　★ Location: It is more common on the scalp and face, followed by the trunk.

　★ Manifestation: Round or oval, soft or slightly tensile, higher than the skin, smooth surface. A black needle hole can be seen in the center, which can squeeze out the white foul-smelling contents. Secondary infection often causes inflammation such as redness, swelling, heat, and pain, as well as ulceration and pus. If not handled properly, the condition will recur. A small number will progress to basal cell carcinoma or squamous cell carcinoma .

　★ Treatment: Surgery is a safe treatment method. The cyst wall and contents need to be completely removed. If the cyst wall remains, it will increase the chance of recurrence. Acutely infected sebaceous cysts should be treated with anti-infection first, and surgery should be considered after the inflammation subsides.

Sebaceous cysts will not disappear on their own. If left untreated, they may slowly increase in size as the contents increase. When the cyst becomes larger before surgery, the surgical incision will be lengthened accordingly and there will be relatively more scars. , the difficulty will also increase. When cysts appear on the face, they can also affect a person's appearance. However, with the improvement of living standards, people's awareness of plastic surgery is gradually increasing. Nowadays, patients not only require complete removal of the tumor, but also want smaller postoperative wounds and lighter scars. To achieve this effect , you need to use plastic surgery and cosmetic suture technology.

　 Plastic and cosmetic removal of sebaceous cyst

　 Plastic surgery can develop a personalized surgical plan based on comprehensive assessment and consideration of factors such as the location, size, age and gender of each patient's cyst, such as:

　★ Surgical incision design , it should be ensured to be as short and hidden as possible under the premise of complete removal of the tumor. Use delicate instruments to achieve minimal trauma and best results.

　★ During the operation, while completely removing the tumor, the surrounding blood vessels, nerves and other tissues are gently clamped to protect it. The resected lesions need to undergo pathological examination to clarify their nature and guide subsequent treatment.

　★ Fine repair suturing is essential, especially for incisions on the face and neck. Sutures with thick needles and large threads should be avoided. Professional plastic surgeons will use cosmetic suture technology to close the wound layer by layer, fully reduce the subcutaneous tension, and perfectly align the skin. . Only in this way can the scars after surgery be smaller and lighter.

　★ Preventive treatment of wounds should be carried out after surgery to prevent scar aggravation, such as laser, injection, topical drugs or dressings, surgery, etc. to treat scars so that postoperative scars are more hidden and minimized.

The patient below came to our department because the chin ridge on the left side was larger than the right side. The soft tissue where the patient had the tumor was thick and it did not look that big from the outside. However, after palpation, our doctor found that the tumor had moved deeper. It grows much larger than it looks on the outside. After the tumor is completely removed during the operation, a cavity is left, which needs to be filled with surrounding tissue flaps. At the same time, cosmetic suture technology is used to close the incision. The scar will not be too big in the later period. The postoperative pathological diagnosis is sebaceous glands. Cyst.
