Is there a possibility of recurrence after the excision of a preauricular sinus?

In general, there is still a possibility of recurrence after surgical excision of a preauricular sinus. Detailed analysis is as follows:

A preauricular sinus is a congenital condition caused by abnormal development of the ear cartilage during embryonic stages and has a certain genetic predisposition, thus making it prone to recurrence. Additionally, the growth characteristics of the sinus also increase the risk of recurrence. Due to the deep base of the sinus, which can reach 1-3 cm and may even extend to the postauricular mastoid area, some epithelial cells may remain after surgical removal, and these cells could potentially lead to recurrence.

The surgery should be performed by an experienced physician, aiming for complete removal of the sinus to reduce the recurrence rate. Postoperative care requires attention to wound cleanliness to avoid infection, and regular follow-up visits according to the physician's instructions are necessary. If any abnormal conditions such as redness, swelling, pain, or discharge occur, prompt medical attention should be sought.

Although the recurrence rate of preauricular sinuses is relatively low, patients should still remain vigilant and actively cooperate with postoperative management and follow-up visits, keeping the affected area clean and dry to prevent infection and ensure optimal treatment outcomes.
