Why did lesions occur on my scalp? Lost hair overtime & been raw & not healing right (Photos)

It sounds like you're experiencing a complex set of symptoms following your craniofacial surgery, which can be concerning. The development of lesions, hair loss, and raw, non-healing areas on your scalp could be due to several factors, including infection, inflammation, or a reaction to foreign materials such as the screws left in place. Here are a few considerations:

Infection or Inflammation: The presence of screws and previous infection might be contributing to ongoing inflammation or infection. This can impede healing and lead to symptoms like pain, swelling, and irritation.

Foreign Body Reaction: Sometimes, the body can react to foreign materials, such as screws, causing chronic inflammation or irritation in the area.

Scar Tissue Formation: Scar tissue from surgery or the body's healing response might affect the surrounding skin and hair follicles, potentially leading to hair loss and changes in skin texture.

Impaired Healing: If the area has been raw and not healing properly for an extended period, there might be an underlying issue affecting your body's ability to heal, such as nutritional deficiencies, immune response issues, or continued irritation from the screws.

Given your symptoms and the complexity of your case, I strongly recommend consulting with a dermatologist or a surgeon experienced in post-surgical complications. They can evaluate your situation thoroughly, possibly recommend imaging studies or biopsies, and determine whether the remaining screws need to be removed or if other treatments are necessary to promote healing and address your symptoms.

Please ensure to seek medical advice from your healthcare provider for a comprehensive evaluation and personalized treatment plan.
