Lip and perioral surgery, like any other esthetic surgery, requires an exact and convenient measurement tool to ensure reliable and reproducible outcomes. Although three-dimensional measuring equipment has proven its effectiveness in measuring facial parameters over the past two decades, it has some drawbacks, including high cost, long scanning times, and non-portability. Thus, digital photography remains the standard tool of measurement in esthetic surgery to date. Many authors have presented evaluation and measurement methods using digital photography in combination with different tools. However, there are no specific tools for the perioral region. Therefore, we devised a specific ruler for perioral measurements. The ruler has differently colored lines for length and angle measurements and a reference point for correct positioning. It can be used in preoperative consultation, intraoperative orientation, and postoperative evaluation.
