PURPOSE: This study was designed to investigate the local subcutaneous fat thickness in sacrococcygeal pilonidal disease. METHODS: Subcutaneous fat thickness was measured by ultrasonography in 125 patients with sacrococcygeal pilonidal disease and 125 age-matched, body mass index-matched and gender-matched controls. RESULTS: The sacrococcygeal subcutaneous fat thickness was 14.4 +/- 2.9 mm, 18.3 +/- 3.1 mm, and 22 +/- 2.2 nun, respectively, in normal, overweight, and obese patients with sacrococcygeal pilonidal disease and 9.1 +/- 3.1 mm, 11.3 +/- 2.6 mm, and 20 +/- 1.8 nun, respectively, in normal, overweight, and obese controls. Sacrococcygeal fat was significantly thicker in normal and overweight patients with pilonidal disease compared with controls with same body mass index (P < 0.01). There were no significant differences in fat thickness between obese patients and obese controls (P > 0.05). CONCLUSIONS: Sacrococcygeal tat thickness, as a local factor, is closely associated with pilonidal disease.
