Thread Migration After Polydioxanone Thread Lift
Research Square (Research Square)(2020)
摘要
Abstract Background: The thread-lift has gained popular interest as a minimally invasive procedure because it is simple and reliable. Additionally, it has shorter recovery time and fewer complications than facelift surgery. However, complications including hematoma, infection, facial asymmetry, thread exposure, thread migration, dimpling, alopecia, parotid gland injury, and scarring can occur. We report a case of thread migration after a polydioxanone (PDO) thread lift.Case presentation: A 40-year-old woman underwent a thread lift using a PDO cogged thread. Insertion sites were marked along the temporal hairline. The expected distal ends of threads were marked at least 1.5 cm apart from the nasolabial and marionette folds and 2.5 cm apart from the mandibular border. All threads were inserted into the deep subcutaneous plane. After 1 month, she complained of a foreign body sensation and pain just lateral to the left mouth corner. She showed a linear elevation with oblique direction, and a linear material was palpated with little mobility. The removed material was confirmed to be a part of the inserted thread.Conclusion:During thread lift, it is important to remove the cannula gently and straightly to avoid breaking the thread. Also, it is better to avoid strong manual massage on the path of the thread.
