title: Angular dermoid cysts in the endoscopic era: retrospective analysis of aesthetic results using the direct, classic method.
abstract: The concept of the endoscopic approach was recently introduced for the removal of angular dermoid cysts. Therefore, it was considered necessary to evaluate the conventional direct incisional approach for angular dermoid cyst excision, with respect to long-term aesthetic results and complications. The need to change from the direct excisional technique to the endoscopic approach in hair-bearing areas was investigated. During a 25-year period, 95 children were surgically treated by a single surgeon (H.G.T.) for removal of angular dermoid cysts. Only 22 patients (23 percent) were available for reassessment. The follow-up periods after the excisional procedure were 1 to 12 years. Assessments were performed by a 15-member team of assessors, who scored the aesthetic results of the scars with comparative slides. In addition, a questionnaire was mailed to each family, to document the family members' perceptions of the aesthetic appearance of the scar. Twenty-eight families (29 percent) responded. The complications were determined through the medical records department. For 19 of 22 patients (86 percent), the scar was scored by 85 percent of the assessors as excellent or good. No assessor stated that a scar was unacceptable. In the family questionnaires, 26 of 28 families (93 percent) reported an excellent scar and two (7 percent) reported a fair scar. No family stated that the scar was unacceptable. The operative notes for the 95 patients revealed that only two cysts had ruptured during the surgical procedure (2 percent) and only one infection had occurred (1 percent). No other major complications were reported. It is concluded that the direct method for dermoid cyst excision is an excellent approach, with a low complication rate and a very high aesthetic success rate, when performed through a supra-eyebrow or infra-eyebrow incision.
