“…33,34 Several centers have attempted to introduce more sophisticated algorithms by using 3-dimensional assessments, automation, and other technologies. [35][36][37][38][39][40][41][42] In response to the need for the development of a diagnostic assessment tool that could rapidly provide quantitative data regarding resting position and dynamic excursion of key facial structures, we developed a straightforward, Java-based software program, Facial Assessment by Com-puter Evaluation (FACE), that provides this information quickly and easily from standard patient photographs. In addition, we compared the accuracy and efficiency of our software with more traditional acquisitions of facial measurements using a ruler tool in Adobe Photoshop (Adobe Systems Inc).…”

“…Moiré topography is a technique that has been reported to be extremely time consuming 17 and requires careful control of lighting that limits the application of this methodology to laboratory conditions. 18 Structured light technology is a technique during which structured light patterns of white light, such as grids dots or stripes, are projected onto the subject.…”

During the preoperative assessment in rhinoplasty, the surgeon takes a thorough history, performs a complete examination by assessing functional and aesthetic aspects of the nose, obtains a clear understanding of the patient's wishes, conducts facial analysis based on standardized photography, and communicates to the patient the goals and pitfalls of surgery. Computer imaging or morphing of the preoperative pictures of the nose has drawn a lot of interest in the last decade, and it is a sign of evolution of the preoperative consultation. Technological advances, also in the context of rhinoplasty, have led to the development of three-dimensional (3D) imaging techniques, and have completely revolutionized the way that surgeons manage their patients preoperatively and evaluate postoperative results today. The accurate 3D surface imaging aids the surgeon to communicate with the patient adequately before surgery, to set an appropriate surgical plan, and to measure the shape and volume changes of the patient's nose that result from the intervention. The present review provides an analysis on the current knowledge of 3D surface imaging in rhinoplasty derived from the literature, and highlights future directions of preoperative and postoperative assessment in the field.

We investigated the usefulness of moiré topography for evaluating facial nerve function in 51 patients with facial palsy and 10 normal volunteers. This method visualizes the shape of objects in three dimensions. We devised three moiré indexes as a simple method of quantifying the severity of facial palsy: the nasolabial groove moiré index, the oral angle moiré index, and the inner canthus moiré index. We compared the results obtained by the moiré indexes with findings obtained using the House-Brackmann grading system and found that they were highly correlated. These three moiré indexes included all the standard factors of the House-Brackmann grading system, allowing us to develop the total moiré index.
