A frenoplasty, also known as frenuloplasty, is a surgical procedure aimed at revising the frenum, which is a small fold of tissue that secures the tongue to the floor of the mouth. This procedure is particularly indicated for patients who experience recurrent ankyloglossia, commonly referred to as tongue-tie, after having undergone previous surgical interventions such as frenotomy or frenectomy. The frenoplasty technique often employed is the four-flap Z-plasty, which is designed to effectively address the complications arising from scarring that may occur after earlier surgeries. In this method, four tissue flaps are utilized instead of the traditional two, as the scar tissue typically extends from the floor of the mouth to the posterior aspect of the tongue. The procedure involves creating two triangular flaps in the floor of the mouth and two corresponding flaps on the tongue, each with an angle of approximately 60 degrees. The lateral incisions must match the length of the central incision, which is strategically placed along the existing scar. The surgical technique requires careful undermining of the incision lines, followed by the rotation and suturing of the flaps to restore normal function and appearance of the frenum.
