Tendon sheath cysts are relatively common surface swellings. Smaller, asymptomatic ones can be observed at any time; larger ones that produce compression symptoms can be handled by physical compression, acupuncture and surgery. 1. Physical compression: patients can go through orthopedic outpatient clinic or hand and foot surgery outpatient clinic, and have the cyst physically compressed by professional doctors, but this method is easy to recur and may cause damage to the soft tissues around the tendon sheaths, so it is necessary to choose carefully. 2. Needle method: the contents of tendon sheath cysts are usually colorless, transparent liquid, so the cyst can be punctured through a syringe to extract the fluid to decompression, and also can be injected into the wall of the capsule, such as dexamethasone and other hormonal drugs to accelerate tissue repair. The above drugs should be used under the guidance of doctors, avoid self-medication. 3. Surgery: if conservative treatment is ineffective in recurrent attacks, surgery is the first choice. Surgery can destroy the wall of the cyst, and at the same time, the cyst can be completely removed from the root of the cyst, which can greatly reduce the probability of recurrence after the operation, and the main surgical method is open cystectomy. If a tendon sheath cyst is diagnosed, early treatment is recommended to minimize the adverse effects of the disease.
