Current Concepts In Performing Matrixectomies

By Alexander Reyzelman, DPM

   Ingrown toenails are one of the most common presenting pedal foot maladies with an estimated 20 percent of those who present seeking foot care for this problem.1,2 Chemical matrixectomy is one of the most common surgical procedures podiatrists perform. Although the technique for the matrixectomy procedure is fairly simple and straightforward, there are many modifications to the procedure and there are controversial issues including the use of adjunctive antibiotics and postoperative care.    In order to understand the evolution of the procedure, one must start with the initial description of this procedure in the literature. In 1945, Otto Boll was the first to discuss the use of phenol in treating ingrown toenails. He described removing the nail edge and swabbing the root with pure phenol for 30 seconds, and subsequently pouring alcohol on the wound. In 1953, Gottlieb described removing the entire nail plate and applying phenol for 30 seconds. In 1956, Nyman reported using two small cotton-tipped applicators to apply phenol for 30 to 40 seconds each. Suppan and Ritchlin described applying phenol for two minutes and following it with a three-minute application of alcohol. In 1965, Cooper reported that alcohol lavage was painful and the length of phenol application made no significant difference regarding healing.    As we know, the phenol matrixectomy procedure has been referred to as a phenol and alcohol matrixectomy. The recommendation for using alcohol comes from the fact that phenol is soluble in alcohol and alcohol will accordingly lavage the excess phenol from the nail groove. The initial belief was that alcohol would minimize the chemical burn that is created by applying phenol. However, Greene believed that using alcohol can create more postoperative drainage and inflammation, leading to prolonged healing time.    In reviewing the history of the phenol matrixectomy, there is no scientific evidence to suggest that using alcohol after phenol application will decrease the healing time. At this time, using alcohol to wash out the phenol is purely anecdotal. Furthermore, the decision to use two or three applications of phenol for 30 or more seconds is purely based on the practitioner’s experience.


Very objective and well described, easy to understand thank you

Thank you. Very good job and clear article.

Thank you Dr. Reyzelman for a very informative article. I just would like to tell you that I prefer to check the vascular status of diabetic patients (if non-palpable pedal pulses) by Doppler.
Thanks again. Good job.
