To the Editor.—Preauricular sinus is common in children and young adults. Management of this congenital anomaly is difficult due to the controversies regarding surgical indications, and a tendency for recurrence or persistence.1 On some occasions, these sinuses become infected, leading to preauricular abscess. These abscesses either burst spontaneously or are incised and drained, leading to scarring and fibrosis, thus making excision difficult. The standard technique for excision involves an elliptical incision around the sinus opening and dissecting out the tract. The use of methylene blue or a probe may aid in the dissection. There is a great chance of leaving epithelial remnants behind that lead to recurrence. The supra-auricular approach has been described recently to avert these difficulties.2 Of late we have managed the excision of preauricular sinuses using the standard technique described, with the aid of methylene blue and an operating microscope with a magnification of
