To provide a more objective evaluation of baldness, the authors have developed a method to calculate baldness quantitatively through a computer-aided imaging system (CAIS). OBJECTIVE To investigate the use of CAIS on Chinese women with FPHL. MATERIALS AND METHODS Thirty-eight Chinese women with FPHL (Savin Scale I-2 to II-2) were recruited. A total of 215 photographs were taken. The central balding areas (CBAs) were calculated after exposure correction by CAIS for comparison with clinical staging. RESULTS The average CBA was 9,391.12 mm2 in all patients, 3,828.84 mm2 in Type I-2, 5,880.38 mm2 in I-3, 8,267.44 mm2 in I-4, 12,999.26 mm2 in II-1, and 15,979.71 mm2 in II-2. The values of CBA correlated with clinical staging using Savin scales. A 7.53% difference was found in the calculated CBA by exposure correction. CONCLUSION The CAIS allows physicians to evaluate the severity of baldness more accurately through quantitative calculation, rather than qualitative visual observation. The values of the CBA measured by the CAIS, used in conjunction with the present grading systems, may be more precise and efficient to evaluate the severity of FPHL. ? 2015 by the American Society for Dermatologic Surgery, Inc. |
