Summary
Free flaps offer reliable reconstruction for chronic wounds, comparable to acute wound treatment. However, chronic osteomyelitis significantly increases reconstructive failure risk by fivefold.
Area of Science:
- Microsurgery
- Plastic Surgery
- Wound Healing
Background:
- Chronic wounds pose a significant challenge due to a lack of standardized surgical treatments.
- Free flap utilization for chronic wounds is underrepresented in literature, often presumed to fail in unfavorable conditions.
Purpose of the Study:
- To analyze the outcomes of free flap application in the curative treatment of chronic wounds.
- To evaluate the reliability and failure factors associated with free flaps in chronic wound management.
Main Methods:
- Retrospective monocentric study of 91 patients undergoing free flap surgery for chronic wounds (January 2001 - September 2016).
- Evaluation of patient demographics, wound characteristics, flap types, and short- to long-term outcomes.
Main Results:
- Free flap survival rate was 92.3% with a mean follow-up of 50 months.
- Reconstructive failure occurred in 20.9% of cases.
- Chronic osteomyelitis was the sole statistically significant factor predicting reconstruction failure (P=0.0169), increasing failure risk fivefold.
Conclusions:
- Free flaps demonstrate comparable reliability in treating chronic wounds to acute wound or post-oncological reconstruction.
- Chronic osteomyelitis is a critical risk factor, elevating reconstruction failure risk by 500%.
- Future research and evolving reconstruction paradigms will refine the role of muscle free flaps in chronic wound management.

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
