Why do ear piercings develop hypertrophic scarring?
In general, ear hole hyperplasia may be caused by improper care, unhealthy diet, scar formation, inflammatory infection, or cartilage overgrowth. Specific analysis is as follows:
1. Improper Care
Improper care and inadequate local treatment can lead to abnormal tissue proliferation around the piercing site, resulting in keloid formation, which presents as a hard lump. Patients can apply warm compresses with a damp towel about twice daily, which may gradually soften the lump and help it subside.
2. Unhealthy Diet
Consuming excessive spicy foods such as chili peppers or mustard may irritate damaged soft tissues at the piercing site, leading to local hyperplasia and swelling. This can be improved by switching to a bland diet.
3. Scar Hyperplasia
A hard lump at the ear piercing site may occur in individuals with a predisposition to scarring (keloid-prone skin). After ear piercing, granulation tissue may proliferate and cause fibrosis of soft tissues near the ear, forming scar tissue. There is no particularly effective non-surgical treatment for this type of hyperplasia; surgical removal is typically required.
4. Inflammatory Infection
If the pierced area is frequently touched with hands or exposed to water after piercing, inflammation and infection may develop, potentially triggering scar hyperplasia. Under medical guidance, patients may use medications such as amoxicillin capsules, cefixime tablets, or cefradine capsules for treatment.
5. Cartilage Hyperplasia
If the ear piercing is placed through cartilage, cartilage overgrowth may occur, often manifesting as scar-like tissue. If symptoms are mild, the hyperplastic tissue is small, and there is no significant discomfort, regular check-ups and maintaining a healthy lifestyle—including sufficient sleep and avoiding late nights—may support natural recovery.
It is recommended that individuals choose reputable medical facilities for ear piercing. High-quality earrings should be used post-procedure to minimize the risk of local infection. Maintaining cleanliness and hygiene at the piercing site is essential; disinfection with iodophor or similar antiseptics is advised.
