What is a phenol and alcohol Matrixectomy?
The fresh phenol is applied with pressure within the nail groove, matrix, and roof of the matrix. The use of an alcohol flush serves as a mechanical irrigation rather than a neutralizing agent. The incorporation of Adaptic serves as a drain which is removed on postoperative day 1 along with the accumulated coagulum.
Does alcohol neutralize phenol?
Conclusion: Alcohol and sterile saline solution do not neutralize phenol but dilute it and aid in its removal. We found that saline solution recovered more phenol than when washing with alcohol and recommend its use instead of alcohol for irrigation purposes after chemical matrixectomy.
What chemical is used in a Matrixectomy?
Phenol is the most commonly used agent for chemical matricectomy, but other agents, such as sodium hydroxide (NaOH) and trichloroacetic acid (TCA), have shown high success rates for the cauterization of the lateral matrix horn (1). However, only a few head-to-head studies have compared the efficacy of these chemicals.
What does phenol do to ingrown toenails?
The aim of phenol therapy is chemical destruction of the lateral and proximal horns of the matrix, and prevention of future growth of the lateral nail plate into the proximolateral nail fold.
How painful is a Matrixectomy?
This in office procedure is painless once the toe is anesthetized. It takes less than a few minutes to complete the procedure. Once the toe is numbed up, the portion or portions of the nail that are causing the pain are removed using special sterilized instruments designed specifically for this procedure.
What neutralizes phenol?
Phenol is neutralized by sodium hydroxide forming sodium phenate or phenolate, but being weaker than carbonic acid, it cannot be neutralized by sodium bicarbonate or sodium carbonate to liberate carbon dioxide.
What is used to neutralize phenol?
At 16°C, phenol is soluble in water at a rate of 6.7% by weight and soluble in all proportions at a temperature of 67ºC. 41,42 It is necessary to use polyethylene glycol 300 or vegeta- ble oil to remove or neutralize phenol.
What is a full Matrixectomy?
Matricectomy refers to the complete extirpation of the nail matrix, resulting in permanent nail loss.
How long does phenol flare last?
Phenol burns Occasionally, the phenol used to stop the nail growing back can spread onto the surrounding skin next to the nail. If this occurs, you may experience mild irritation / discomfort. This usually resolves itself after two to three days and normal healing will take place.
What should I do after a Matrixectomy?
For the first few days use gauze to cover the toe instead of a Bandaid, this allows the toe to breath. Once the drainage is minimal you can switch to a Bandaid. Keep it covered at all times for the first 34 days with gauze.
