Ordering this service voids the discount*
Radiofrequency surgical removal (excision) of a pigmented nevus is a minimally invasive procedure used to remove benign pigmented skin lesions with high-frequency radio waves. The technique allows precise excision of the lesion while minimizing impact on the surrounding tissues. Prior to the procedure, the physician performs a clinical examination and dermoscopic assessment to determine the most appropriate treatment approach.
Indications
- Benign pigmented nevi requiring removal for medical or aesthetic reasons
- Recurrent trauma to the nevus caused by clothing, jewelry, or shaving
- Lesions located in areas exposed to constant mechanical irritation
- Discomfort associated with the presence of the nevus
- Changes in the appearance of the lesion requiring specialist evaluation
- Patient’s desire to remove a benign skin lesion for cosmetic reasons
Procedure / Duration
The procedure is performed on an outpatient basis under local anesthesia. After skin preparation and administration of anesthesia, the physician performs radiofrequency surgical excision of the nevus. When indicated, the excised tissue may be sent for histopathological examination. The procedure usually takes between 15 and 30 minutes, depending on the size, location, and number of lesions.
Recovery / Restrictions
Following the procedure, a natural protective crust forms at the treatment site and gradually falls off as the skin heals. During the recovery period, patients are advised to avoid trauma to the treated area, as well as saunas, hot baths, swimming pools, and excessive exposure to sunlight or tanning beds. The physician’s aftercare recommendations should be followed until complete healing is achieved.
Contraindications
- Acute infectious diseases
- Inflammatory skin conditions or lesions in the treatment area
- Decompensated chronic diseases
- Blood clotting disorders (subject to physician assessment)
- Individual contraindications identified during medical consultation
Benefits
- High procedural precision
- Minimal trauma to surrounding tissues
- Outpatient treatment without hospitalization
- Short procedure duration
- Favorable conditions for tissue healing
- Possibility of histopathological examination of the excised tissue when indicated
