Abstract: Objective To study the anatomic structure of suborbicularis oculi fat pad（SOFP）to guide the management of SOFP in the operation of removing the eyelid pouch and the plastic operation of lower eyelid in order to improve the curative effect of cosmesis. Methods The locations of SOFP in 48 corpse skulls (96 sides) were observed. The thickness of SOFP was measured. The comparisons of SOFP in different ages, sex, and somatotypes, between left side and right side in one corpse were made. Results The SOFP located the outside of orbit；among of suborbicularis oculi， top jaw bone and zygomatic bone′s periosteum. The fat pad′s appearance was irregular, connecting with each other, and with surroundings fat mat continuously, and the boundary was not clear. The SOFP′s thicknesses were 2.49-2.78 and 2.49-2.84 mm， respectively, in 20-30 and >30 years old (mean values were 2.66 and 2.68 mm, respectively). The SOFP′s thicknesses of males and females were 2.40-2.98 and 2.53-3.04 mm respectively (mean values were 2.75 and 2.79 mm, respectively）. The SOFP′s thicknesses of left side and right side were 2.53-2.65 and 2.51-2.69 mm（mean values were 2.59 and 2.61 mm, respectively ）. Therefore no significant differences of the SOFP′s thickness were found in different sex, ages or sides（P>0.05）. The SOFP′s thicknesses of emaciated, moderate, and obese somatotypes were 2.40-2.65,2.73-2.89, and 2.96-3.04 mm（mean values were 2.54, 2.81, and 2.99 mm, respectively）.So there were significant differences of SOFP′s thickness among different somatotypes (P<0.05). Conclusion In the plastic operation of eyelid pouch, the SOFP should be cut off at the same time, or reply the mistaken fat pad to improve the curative effect.
