Brief Summary:

Ingrown toenail is a very common disease in the general population that touches young adults. There are lots of treatments from local care of pedicure to surgery with matricectomy. Gold standard of symptomatic and painful ingrown toenail is the simple surgery with matricectomy and with suture or directed healing pad.

For many years chemical cauterisation with phenolic acid is used, a method with very few relapses and with a more simple pad. However, because of a lack of information about this phenolic acid, the pharmaceutical laboratory withdrew it from the market.

The new method to replace phenolic acid is trichloroacetic acid, used mainly in cosmetics for peeling. This method was already compared to phenolic acid and showed equal results with fewer laps of application and a low cost. The comparison between acid trichloroacetic method and the gold standard surgery was never done and will be the goal of this study.

It's an open, non randomised, comparative, multicentric (2 centers) study with two groups : common surgery and surgery with chemical cauterisation For this study the investigators will compare between the two groups : gain of quality of life at one month after surgery, difference of pain between before, one week and one month after surgery, the occurrence of adverse events and number of relapses at one year.

Official Title: Etude Comparative Multicentrique Prospective évaluant la Prise en Charge Chirurgicale associée à Une cautérisation Chimique Par Acide TCA Par Rapport à la Prise en Charge Chirurgicale Standard Dans le Traitement de l'Ongle incarné
Actual Study Start Date : September 1, 2020
Estimated Primary Completion Date : September 1, 2022
Estimated Study Completion Date : September 1, 2022

Arm Intervention/treatment
Experimental: Dermatologic intervention
Surgery with chemical cauterisation TCA
Procedure: Ingrown toenails with surgery with chemical cauterisation
Removal of the ingrown lateral part of the toenail and chemical cauterisation

Active Comparator: Orthopedic intervention
Only surgery
Procedure: Ingrown toenails with only surgery
Removal of the ingrown lateral part of the toenail with directed Healing pad

Primary Outcome Measures :
  1. Relapses [ Time Frame: one year ]
    Relapses of ingrown toenail on the operated nail

Secondary Outcome Measures :
  1. Gain of quality of life [ Time Frame: Baseline and one month after the surgery ]

    Quality of life will be measured with the Dermatology Life Quality Index adapted to the nail, there are 9 questions that will be filled by the patient. Each questions have 4 possibilities to 0 (no problem) to 3(hugely). So the score go to 0 to 27.

    Questions are, on last 7 days :

    • Did your nail itch, burn or hurt you ?
    • Did you feel embarrassed or complexed by your nail ?
    • Did you have problem to go shopping, to do the housework ?

    • Did your nail embarrased you in your job or your studies ?
    • Did your nail complicate your relationship's with your friends, parents or spouse?
    • Did your nail deteriorate your sexual life ?

  2. Complications [ Time Frame: At one week and one month after surgery ]
    Bleeding, infection, pain

  3. Pain on the nail [ Time Frame: Baseline, one week and one month after surgery ]
    Pain report on a numeric scale of pain to 0 (no pain) to 10(worst pain possible)

  4. Time before restart sport [ Time Frame: Restart sport at one month yes/no ]
    Time to recover a normal physical activity
