{Abstract}: <B>OBJECTIVE: </B>To analyze the upper eyelid contour after Müller's muscle conjunctiva resection (MMCR) performed by four different surgeons.<BR><B>METHODS: </B>Comparative cross-sectional analysis of the pre- and postoperative contours of a control group and four groups of upper lids (n = 88) of 65 patients who underwent MMCR at four international centers. The procedure employed was essentially the same as described by Putterman but performed with different instruments to entrap the posterior lamella. Multiple medial and lateral margin lid distances were measured on Bézier lines expressing the pre- and postoperative lid contours.<BR><B>RESULTS: </B>Preoperatively, two groups had significant lateral and medial ptosis. After MMCR, the lateral segment of the lid's contour was corrected in all groups. In the two groups with more pronounced ptosis, the nasal lid contour was undercorrected.<BR><B>CONCLUSIONS: </B>In MMCR, regardless of the instrument used to entrap the posterior lamella, the amount of medial tissue resection is essential to avoid postoperative nasal undercorrection.<BR><B>METHODS: </B>This journal requires that authors assign a level of evidence to each article.
