“…Assessments for lip function include lip texture, symmetry, movement, mass formation and ease of repeating the injection. Moreover, achieving aesthetic goals with minimal risk for adverse events requires knowledge of lip anatomy and function, clinical experience in the use of various injection techniques, the primary reason for the patients to demand these treatments is to improve their appearance [3,18,23]. Therefore, either surgical or nonsurgical, lip augmentation procedures should be based on recording mathematical measurements of the individuals and their evaluation on ethnic characteristics.…”

“…Lip defects of congenital deformities such as cleft lip, holoprosencephaly, fetal alcohol syndrome and other defects such as tumor resection, traumatic injuries and flattened lips as agerelated or facial paralysis require redesigning with aesthetic and cosmetic approach [17][18][19]. Together with the surgical techniques, nonsurgical procedures of injectable soft tissue fillers such as bovine collagen or hyaluronic acid enable to enlarge, refine, shorten and reshape lips.…”

Background Lip augmentation and changing contour lines have become more popular ways of improving the appearance. However, validated measures of lip fullness for quantification of outcomes are needed; ethnic background and personal goals can optimise outcomes while tailoring lip enhancement treatment to each individual's anatomy. The aim of this study is to analyse the morphological features of the lip in detail and to clarify the objective parameters in related with the subjective ones regarding the lip augmentation and lip reconstruction. Methods Standard photographs of the lips of 200 young Anatolian adults were calculated with linear and angular components. The features of the lower third of the face were analysed with the software program. Linear analyses (heights of the upper lip, the upper vermilion, the lower lip height, the lower vermillion and the chin height) and angular analyses (the upper lip, the lower lip, the apex and Cupid's bow angles) were measured as reference points. The lip shape was classified into five groups: thin, very thin, medium, full and very full. Results The lower third of the face was divided into three segments (Sn-Sto, Sm-Me and Sto-Sm), and the largest portion of the lower face was occupied by the chin and the smallest by the lower lip height in both genders. The upper vermilion height was 8.07 ± 1.8 mm in males and 7.08 ± 1.5 mm in females. The lower vermilion height was 10.1 ± 2.4 mm in males and 9.7 ± 1.9 mm in females. The upper lip angle was calculated as 30.3 ± 9.6°in males and 24.2 ± 6.2°mm in females. The lower lip angle was calculated as 38.3 ± 9.7°in males and 36.5 ± 6.4°in females. Meanwhile, the angular measurements of Cupid's bow (i.e., the apex and the central angle of Cupid's bow) were smaller in men than in women. When the lip was analyzed, the medium and full types in upper and lower lips accounted for substantial fractions in men, whereas medium and thin types were predominant also in women. Conclusions With the help of certain software, this research has made possible to define the best cosmetical redesign solution of lip construction and augmentation with a natural appearance for the patient. Level of Evidence: Level III, diagnostic study.

“…Particularly in patients with a CLP an analysis of the facial asymmetry as follow-up documentation and objective evaluation of the treatment results could be more comprehensive and reproducible by using 3D techniques (Nollet et al, 2007;Nagy and Mommaerts, 2007). These methods based on reliable data lead to the introduction of a 3D facial asymmetry degree by using single landmarks on both hemifaces (Mommaerts and Moerenhout, 2008;Schwenzer-Zimmerer et al, 2008).…”

“…Cleft repair is an integral part of the modern craniomaxillo-facial surgical spectrum and remains a challenge because of insufficient and malformed tissue (minor to major) at the site of the deformity (Mommaerts and Nagy, 2008;Nagasao et al, 2008;Schwenzer-Zimmerer et al, 2008). This in itself will influence the short and longterm aesthetic (soft tissue and facial skeletal appearance) (Nagy and Mommaerts, 2007;Nollet et al, 2007) and functional (occlusal and speech) outcomes (Joos et al, 2006).…”

SUMMARY. Background: The repair of the lateral or transverse facial cleft is a surgical challenge on the account of the abnormal positioning and appearance of the cleft. Materials and methods: Over a twenty-seven year period, 22 lateral facial cleft cases were evaluated at a cleft lip (CL) and palate clinic and seven children underwent reconstruction of the lateral CL. Results: Twenty-two of 3187 (0.69%) cases presented with a lateral CL. Five of these 22 cases (23%) had a bilateral, eight (36%) had a right-sided and nine (41%) had a left-sided cleft. The evaluation of these cases resulted in a new classification (namely an extension of the Tessier 7 cleft) classification for the cutaneous and muscle involvement: a superior (T7.1), middle (T7.2), inferior (T7.3) and agenetic (T7.4) lateral CL. The altered surgical construction: an internal mucosal straight-line closure, a curved cutaneousemucosal red-lip/vermilion-lined flap for the lip commissure, muscle reconstruction at the modiolus and a positional cutaneous z-plasty for the rare lateral cutaneous cleft. Conclusion: The paper introduced a new classification for the lateral CL, as well as an altered surgical reconstructive technique for the most natural functioning of the lateral part of the face.
