The first photo below shows the evil ingrown nail before we started. This patient has chronic and recurrent ingrown nails on the left side of the toe (fibular border). This toe killed her in shoes. She wanted desperately to get this toe better. Others tried and others failed. Now it was my turn. The first photo below shows the painful toe. Notice that besides some redness, the toe looks normal. The offending nail border is down in the side of the toe where you cannot see. I begin by injecting the base of the toe with plain Xylocaine after first spraying the injection site with enough Ethyl Chloride (aka freezy spray) to pre-freeze the skin. I use the smallest syringe and the smallest needle made for this injection. I find these little needles and syringes produce the least amount of pain. I follow the Xylocaine injection with a second injection of long acting Marcaine. I do not start with the Marcaine because it stings so much going into the tissues that I want the toe first made numb with the gentle Xylocaine.
Also note that I inject at the base of the toe where the skin is loose and movable. Injecting it at the tip of the toe where it is ingrown (a favorite trick of some urgent care centers) is cruel and unusual punishment. After securing anesthesia of the toe it is scrubbed with a clear anti-bacterial solution called Clorahexidine. Next I place a blue “toe-niquet” over the toe to keep any ‘red stuff” out of the wound site. Not only do I not like the sight of the red stuff but it interferes with the effectiveness of the acid I use to kill the nail root. Next I use a tiny tool called a curette to loosen the skin away from the edge of the edge of the toe nail.
After freeing the edge of the nail plate I use an fancy nail cutter called an English Nail Splitter to cut the edge of the nail parallel to the side of the toe After cutting the side of the nail plate I use a little tweezer like instrument called a mosquito hemostat to reach in and grab the piece of nail that was inside the toe. Done correctly you do not have to remove any nail that you can see – just the nail that is inside the toe itself
After the edge of the nail plate is removed it is time to kill the edge of the nail root that causes the edge to grow. I use an applicator stick (medical speak for a Q-Tip) that was dipped in an acid called phenol. To kill the nail root requires two or three applications of phenol placed directly on the nail root tissue. Finally the toe-niquet is removed and the toe is dressed with an antibiotic cream, sterile gauze and covered with a compressive bandage called Coban (here it is purple).
Matricectomy Post-Operative Instructions:
- It is best to return home and elevate the foot/feet until the feeling returns (which can take from 2 to 6 hours). At that time remove the stretchy Coban covering the gauze. Delay taking a shower or bath for 12 hours from the time of surgery.
- Clean the nail border(s) using any one of the three interchangeable methods (not all 3 at the same time):
- A) Using a shower of clean tap water – holding the toe(s) under the shower using it like a shower-pic.
- B) Clean the edge of the nail plate with a Q-Tip and hydrogen peroxide
- C) Soaking in an (Epsom or kitchen) salt solution and cleaning the wound edge with a Q-Tip
- Tomorrow morning do the first cleaning of the toe(s). Remove the white dressing and clean the wound(s) using one of the three methods that are interchangeable. After cleaning the nail border(s) please dress the wound with the prescription antibacterial and cover the toe with a Band-Aid. Wear regular shoes that are not too tight on the toes.
- Keep the wound clean including avoiding getting dirt or sand into he wound and showering only with a Band-Aid or other covering on the toe(s) until healing is complete. Wounds do not heal faster if they are allowed to “dry-out” or “air-out”
- Call the office if the toe becomes more swollen, painful or red than you think is normal.
- Please schedule a follow-up visit for 3 to 5 days after the procedure.
