Healing time for an upper ear cartilage avulsion can vary depending on the severity of the injury and the quality of medical care received. Typically, with immediate and proper medical care, it can take several weeks to a few months for the cartilage to heal.

Here are some techniques and treatments that can help speed up the healing process:

1. **Immediate Medical Attention**: Seek immediate medical care to clean the wound, prevent infection, and properly align the cartilage.

2. **Sutures**: In many cases, sutures are used to reattach the cartilage and skin. This helps to hold the tissue in place and promote proper healing.

3. **Tissue Adhesives**: Medical-grade tissue adhesives (glues) can sometimes be used to close small wounds or assist in the healing process. These adhesives are designed to be safe for use on the skin and can help reduce the need for sutures.

4. **Antibiotics**: To prevent infection, antibiotics may be prescribed. Keeping the wound clean and free from infection is crucial for faster healing.

5. **Pain Management**: Proper pain management can help reduce stress on the body, which can aid in the healing process.

6. **Follow-Up Care**: Regular follow-up visits with a healthcare provider are important to ensure the wound is healing properly and to address any complications that may arise.

7. **Avoiding Trauma**: Protect the injured ear from further trauma or pressure during the healing process.

8. **Healthy Lifestyle**: Maintaining a healthy diet, staying hydrated, and avoiding smoking can also promote faster healing.

Always consult with a healthcare professional for personalized advice and treatment options.
