Preface: The Asian race has a high prevalence of congenital entropion. It was reported that over 20% of Japanese children have congenital entropion at the age of 1 year. One of the structural causes of this condition is the development of epiblepharon, which attaches the lower eyelid to the upper eyelid, and is also common among Asians. However, designing a procedure for modifying an epicanthus flap is relatively difficult, and epicanthoplasty is not a popular procedure in Japan. In the present study, we developed an easy method of designing the surgery, and we describe both the surgical procedure and the outcome.
Cases: Between January 2010 and August 2011, one surgeon performed surgery to correct congenital entropion in 28 patients. We analyzed this series of 28 cases retrospectively. The patients consisted of 17 females and eleven males with an average age of 7.6 years. Ten patients with a thick epicanthal fold required epicanthoplasties in addition to lower lid procedures, and 18 patients with a thin epicanthal fold required only lower lid procedures.
Surgical method: On the epicanthus, a small, triangular “fish-tail” flap that was 2 mm wide was designed and was located adjacent to a “fish-body” marking on the subciliary lower eyelid. After fish-tail resection, the residual medial edge was sutured to the corner of the epicanthus. A C-shaped epicanthus was changed into an L-shape by means of this procedure.
Result: The fish-tail resection diminished the tension of the orbicularis in the superior direction. After a minimum of 6 months, the shape of the medial canthus remained L-shaped, and the cilia had stable orientations.
Conclusion: This plasty is easy to design in conjunction with a Hotz procedure, and it is an effective means of correcting Asian congenital entropion. Recognizing the shape of a congenital entropion that is accompanied by epiblepharon is important for its radical treatment.
