Background:
Digital block with epinephrine is safe in selected patients. Chemical matricectomy with phenol is a successful, cheap, and easy method for the treatment of ingrown nails.
Objective:
To determine the effect of digital block with epinephrine in chemical matricectomy with phenol.
Material And Methods:
Forty-four patients with ingrown toenail were randomly divided into two groups. The plain lidocaine group (n=22) underwent digital anesthesia using 2% plain lidocaine, and the lidocaine with epinephrine group (n=22) underwent digital anesthesia with 2% lidocaine with 1:100,000 epinephrine. In the postoperative period, the patients were evaluated for pain, drainage, and peripheral tissue destruction and were followed for up to 18 months for recurrence.
Results:
The mean anesthetic volume used in the epinephrine group (2.2 ± 0.4 mL) was significantly lower than the plain lidocaine group (3.1 ± 0.6 mL). There was no statistically significant difference in postoperative pain and recurrence rates, but duration of drainage was significantly shorter in the epinephrine group (11.1 ± 2.5 days) than in the plain lidocaine group (19.0 ± 3.8 days). CONCLUSION Digital block with epinephrine is safe in selected patients, and epinephrine helps to shorten the postoperative drainage period. The authors have indicated no significant interest with commercial supporters.
