Comparison of phenol applications of different durations for the cauterization of the germinal matrix: an efficacy and safety study

OBJECTIVES Partial nail avulsion with phenol matricectomy is one of the most widely performed procedures for the treatment of ingrowing nails. We compared phenol applications of different durations with respect to efficacy and safety. METHODS The study included 148 ingrowing nails (grade 2-3) of 110 patients (54 males, 56 females). The patients were randomized to three groups for 1-, 2-, and 3-minute applications of phenol cauterization of the germinal matrix following surgical removal of ingrowing nails. Postoperative evaluations were made on days 2, 10, 16, 24, and 30 for pain, drainage, and tissue damage. Recurrences were recorded during a follow-up of 24 months. RESULTS Improvements in pain, drainage, and tissue damage in each group were significant (p<0.001). Time to complete healing and durations of drainage and tissue damage were significantly shorter in patients receiving 1-minute phenol application (p<0.001), and the remaining groups did not differ in this respect. The mean duration of pain was similar in three groups. While the frequencies of pain and tissue damage were similar in three phenol groups, the number of patients having drainage on day 16 was significantly lower with 1-minute phenol application (p<0.001). All recurrences appeared in the sixth month and there was no significant difference between the three groups with respect to the recurrence rate. CONCLUSION Our findings suggest that 1-minute phenol cauterization of the germinal matrix has a better safety profile than prolonged applications in the treatment of ingrown nails.

Clinical results versus subjective improvement with anterior transposition in cubital tunnel syndrome

This study was conducted to compare the results of anterior transposition methods and to determine the time needed to attain subjective well-being in patients with cubital tunnel syndrome. A total of 49 cases were retrospectively evaluated. Patients were called for follow-up, completed a questionnaire, and were reexamined. They were assigned to one of 3 groups: subcutaneous transposition (SCT), submuscular transposition (SMT), or intramuscular transposition (IMT). The McCowan classification and Wilson-Krout criteria were used for classification and outcomes assessments. Categorical variables were analyzed with the χ2 test, and metric variables by analysis of variance or through Kruskal-Wallis variance analysis. Improvement of at least 1 McCowan grade was observed in 87.63% of patients. The least responsive group was assigned a McCowan grade of III. The most effective procedure for resolving clawing was SMT. Clinical results were excellent in 26 patients (53.06%), good in 12 (24.48%), fair in 4 (8.16%), and poor in 7 (14.28%). At the latest follow-up, overall grip and pinch strength had improved by 23% and 34%, respectively, compared with the contralateral side. Thirty-six patients exhibited an improvement in grip power and 38 in fine dexterity. Complete resolution of numbness was observed in 32 patients, and complete resolution of pain was noted in 30 patients. The preoperative mean visual analog scale score of 6.82 improved to 3.36 postoperatively. Clawing improved in 4 patients and atrophy in 7. The mean time to subjective improvement was shortest in the SMT group and longest in the IMT group. The greatest pain relief was reported in the IMT group and the least in the SMT group. One case with IMT required reoperation because of recompression of the nerve. The most frequent complication in the SMT and IMT groups was muscular tenderness. In conclusion, SCT offers an alternative to other anterior transposition methods because of its simplicity and quicker recovery time, especially in mild to moderate cases.
