A study of the Geheimratsacken angle as predictor for early diagnosis of androgenetic alopecia in adolescent population

Background: Aim: To Know the role of Geheimratsacken angle (Fronto-Temporal Denudation)in hairline recession of adolescents. To know the morphology and latest trends of hairline pattern in adolescent population. Material: Specially designed measuring spectacle, Measuring tape, Skin marking pencil, Compass divider. Method: Equally represented 350 healthy subjects were examined between 12 to 19 years age. Using Frankfurt’s horizontal plane, the hair line drawn was measured from glabella for 0 to 180 degree with measurement of head circumference. Results: The recession starts at the Right and Left Gehiemratsacken Angles and is observed at more than one degree points. The highest recession seen at the Left Gehiemratsacken Angle, makes it a marker for identification of the earliest manifested hair line recession. Conclusion: The age of onset of hair line recession is 14-15 years. The hair line recession in the subsequent ages become most marked as found in 16-17 years and 17-18 years. The highest recession is seen at the Left Gehiemratsacken Angle. As the specific findings of hair line pattern and the age of its onset are found out, it can be of great use for prevention of Androgenetic Alopecia through observance of timely intervention in vulnerable adolescents.
