How long does it take for an infected preauricular sinus to drain pus?

　　The duration of pus drainage during an infected preauricular sinus varies among individuals, typically lasting 7 to 14 days. The exact timeframe depends on individual factors. If symptoms persist without improvement over an extended period, prompt medical consultation is recommended. Below is a detailed analysis:

　　In cases of mild inflammation, where pus drains easily, the drainage period may be relatively short—usually around 7 days. However, if the sinus tract is deep and significant pus accumulation occurs, the drainage period may extend up to 14 days. Patients with compromised immunity often experience prolonged inflammation control and delayed healing.

　　Different treatment approaches influence the duration of pus drainage. For instance, patients undergoing puncture irrigation with intrasinus medication typically exhibit markedly accelerated resolution of inflammation and wound healing, often achieving full recovery within 7 days. Additionally, good daily care practices—including keeping the ear clean, avoiding squeezing or scratching, and maintaining a light, bland diet—can also help shorten the drainage period.

　　Patients are advised to undergo treatment under the guidance of a physician and adhere to proper daily care: avoid water exposure to the affected area, follow a light diet, and consume appropriate amounts of vegetables and fruits—such as Chinese cabbage and citrus fruits—to support recovery.
