Comparison of Surgical Techniques for Medially Ingrown Toenails: A Prospective Randomized Study

Introduction:

Medially ingrown toenail (Onychocryptosis) is a common foot condition that significantly affects patients by causing pain and discomfort, particularly while walking or wearing shoes. The condition is characterized by localized inflammation and bacterial infection around the nail bed, leading to purulent discharge. Patients with ingrown toenails are classified using the Hefetz classification system.

The treatment options for ingrown toenails are diverse, including both conservative and surgical approaches. The primary objectives of surgical interventions are to reduce recurrence rates, improve patient quality of life, and achieve optimal cosmetic outcomes. In this study, we aimed to compare the recently introduced Bird Flap (a modified Winograd technique), Noel's technique, and the classic Winograd method in terms of recurrence rates, patient-reported quality of life, cosmetic appearance, and postoperative pain.

Methods:

This study included three different surgical techniques applied to three separate patient groups.

• Group 1 (n=36): Patients underwent the modified Winograd "Bird Flap" technique, which involves an incision resembling the contour of a sparrow's body. Through this approach, the lateral nail bed, proximal germinal matrix, and granulation/infected tissue down to the bone were excised and subsequently sutured using prolene.
• Group 2 (n=36): Patients underwent the modified Noel technique, which involved a 4-6 mm semi-elliptical incision adjacent to the lateral margins of the nail bed, targeting the granulated tissue. Unlike the Bird Flap technique, this approach preserved the nail bed and proximal germinal matrix, with only the inflamed soft tissue and granulated tissue excised. The wound was then sutured subungually using prolene.
• Group 3 (n=36): Patients underwent the classic Winograd technique, which is the traditional method for ingrown toenail surgery. A linear incision was made to separate the nail bed from the soft tissue, followed by excision of the lateral edge of the nail bed and the germinal matrix in a linear fashion. The wound was then sutured accordingly.

Postoperative Follow-up and Outcome Measures:

All patients had their sutures removed on postoperative day 20 and were evaluated at 1-month, 2-month, and 3-month follow-ups.

• Primary Outcome: Recurrence rate
• Secondary Outcomes: Healing time, complications (bleeding, infection, wound site problems), and overall recovery and personal cosmetic satisfaction
• Pain, functional impact, and quality of life were assessed using the European Quality of Life Instrument (EuroQol) test.

This structured comparison provides insight into the effectiveness of these three distinct surgical approaches in managing medially ingrown toenails, with an emphasis on clinical and patient-centered outcomes.
