N/A Changes in Nasolabial Angle and Nasal Tip Projection. Tongue in groove surgical technique by definition involves a method by which the medial crura is pulled posteriorly over the caudal part of the nasal septum, in fact this is a type of intervention on the treated specimens. Some angles, such as nasolabial angle or nasal projection, are within the normal range,by using this method. This technique also has effects such as correction of septal deviation or colomellar overexpression, which were not examined in this study. Non-use of cartilage, this technique is more and more popular todayThe study is a comparative study ;before and after using the technique. The groups undergoing surgical intervention using the above technique will be measured after angular and projection correction . It is technically sensitive and has very stable results, technically most surgeons refuse to do it and prefer simple techniques with poor results, but in aesthetic practice long-term survival is the principle..
