Ingrown toenail is a common condition seen in our clinics. A deformity characterized by a transverse over curvature of the lateral nail plate that causes nail fold irritation and then inflammation. Patient usually present with pain on the affected nail but with continuing progression, drainage, infection, and difficulty in walking occures. Prevalent during the second and third decades of life, often develop to poorly fitting shoewares or infection after manipulation of the corners of the toenails. This study was done to compare the three surgical techniques, the Winograd, the Limited partial and the simple ungiectomy, with a longer follow-up period (2-3 years) and to finally put to rest the controversies brought about by the previous studies.

To compare the conventional matricectomies against the conventional simple ungiectomy in both recurrences, infection and satisfaction rates.

Prospective, randomized, analytical study

Out-patient Department, Jose R. Reyes Memorial Medical Center

83 patients were enrolled for a total of 93 ingrown toenails

By using the table of random numbers, 25 patients were assigned to the partical matricectomy group, 29 to the limited partical matricectomy and finally 30 to the simple ungiectomy group. All patients were followed up for a minimum of 2 years, rates of recurrences and infections as well as their satisfaction rates were taken.

Rates of recurrences and infections per group. Patient satisfaction rates after the treatments.

Z-test comparing the three groups showed no significant difference between each of them in both recurrence and infection rates except for simple ungiectomy and partial matricectomy in infection. As with regards to the satisfaction rates, the majority of patients belonging to group I (48%) are satisfied, group 2 (62%) are very satisfied, and while at group 3 (90%) are also satisfied with their results but Z-test showed no significant differences F-test (NOVA) showed significant differences in the operating times of the three groups.

There is no significant difference in the recurrence and infection rates whether you do a simple ungiectomy, a partial, nor a limited partial matricectomy in the treatment of ingrown toenails except for one, that the simple ungiectomy has significantly lower infection rates compared to the partial matricectomy. Satisfaction rates are similar results if not better for the limited partial matricectomy group compared contrary to published foreign literature, the main cause of ingrown toenails for our study is due to manipulation of the nails and not due to poorly fitting shoe wares.
