Lip morphology and aesthetics: study review and prospects in plastica surgery

Si-Qiao Wu, Bai-Lin Pan, Yang An, Jun-Xue An, Lu-Jia Chen, Dong Li


ABSTRACT: The lip profile plays an important role in the perception of facial aesthetics; lip morphology and aesthetics research is receiving increasing attention. The advancement of research tools such as three-dimensional imaging technology has led to the clarification of lip morphologic and aesthetic characteristics. After studies of lip characteristics according to gender, ethnicity and age provided basic data, studies on lip aesthetics have been conducted by scholars worldwide. These studies could provide a basic theory to support diagnosis and treatment options, as well as the basis for evaluative criteria for precise treatment and technical improvements. According to the conclusions of the above studies, new ideas for cosmetic surgery design, including lip, perioral and labial-facial relationships, have been discovered.

Do I know the anatomy of the lips? Implications for a successful filling

Maurìcio Pedreira Paixao


ABSTRACT: The lips are important anatomical units for perfect facial aesthetic balance. A number of methods can be used to improve lip appearance, including chemical and physical peels, botulinum toxin, cosmetic surgery and the use of cutaneous fillers. In the face of the already widespread and yet still growing use of fillers worldwide, the need for precise anatomical knowledge arises as an important tool to prevent complications. The objective of the present study is to shed light on the anatomical peculiarities of this facial topography and review recommendations linked to best practices with cutaneous fillings.

Perioral rejuvenation in aesthetics: review and debate

Sungat Kaur Grewal, Arisa Ortiz


ABSTRACT: Perioral rhytides are a common reason for presentation to the cosmetic dermatologist. Various treatment options exist, and it can be challenging to determine the optimal technique to use in a given patient encounter. We herein provide a review article highlighting various treatment options in the correction of perioral rhytides, focusing on the roles of neurotoxin, filler, microneedling (with and without radiofrequency), fractional resurfacing (nonablative and ablative), and fully ablative lasers, with a brief mention of deep chemical peels. For each modality, we review the evidence behind the specific technique, its advantages and disadvantages, post-procedural effects, expected downtime, as well as the onset and duration of desired effects. Despite longstanding debate regarding the "best" modality to use, we instead propose that the best approach is a combination approach which takes into account he patient's treatment goals while staying consistent with the expected amount of downtime.

Improving lip aesthetics in the face profile after treatment of class II, division 2 malocclusion

Zuzana Koniarova, Romana Husarova, Marie Stefkova, Milos Spidlen, Dagmar Statelova, Maria Janickova, Alena Koniarova


AIM: The aims of our research were as follows: 1) Description of changes in the position of the upper and lower lips, as a result of the change in the position of upper and lower incisors after orthodontic treatment of malocclusion of Class II, division 2 type. 2) Determination of correlation between changes in the position of lips and incisors in the profile of the face after orthodontic treatment of malocclusion of Class II, division 2 type.


MATERIALS AND METHODS: Our study analyses the documentation of 115 patients with malocclusion of Class II, division 2 type treated with a fixed orthodontic appliance in the upper and lower dental arches at the Orthodontic Department of the Clinic of Dentistry in Olomouc from January 1, 1996 to December 31, 2017. There were 78 women and 37 men aged 11 to 36 years included in the database. Cephalometric images of patients from the group taken before and after the treatment were used for the purpose of cephalometric analysis according to Kamínek (1) and Burstone's analysis (2) of soft tissues. Subsequently, all output data were processed statistically.


RESULTS: While the protrusion of the incisors after treatment of malocclusion of Class II, division 2 type was 3 mm, the facial profile showed statistically significant changes in soft tissues in the ventral direction by 1 mm on average just in the area of the upper and lower lips, which means a shift corresponding to one third of teeth movement.


CONCLUSION: A statistically significant change in the position of incisors, soft tissues as well as correlation between changes in hard and soft tissues in the face profile after orthodontic treatment of malocclusion of Class II, division 2 type were demonstrated. The more the incisors were inclined, the more the lips moved forward, and the patient's profile turned out to be aesthetically improved (Tab. 2, Fig. 3, Ref. 39).

Proposed guide to lip treatment in caucasian women using objective and measurable parameters

Giuseppe Sito, Luana Consolini, Patrick Trèvidic


BACKGROUND: The lips are a focal point of the face; however, their aesthetic proportions and effect on perceived facial beauty remain poorly defined. Perioral aging is highly individual, with several distinct and often simultaneous processes contributing to changes in lip contour and surface. These processes can affect lip volume and length, shape, and the degree of vermilion inversion.


OBJECTIVES: We aimed to develop a treatment guide for Caucasian women that combined a complete analysis of the lips (including the effects of aging) with consideration of the rheological characteristics of the products used to assist practitioners in tailoring rejuvenation treatment to individual patients.


METHODS: We reviewed existing literature to analyze the parameters that make the lips of Caucasian women "attractive" and investigated the rheological characteristics of different hyaluronic fillers to provide guidance on the optimal treatment for each woman.


RESULTS: Our numerical definition of the lips is based on 4 specific parameters: philtrum height, upper vermillion height, ratio between philtrum and upper vermillion height, and golden ratio between upper and lower vermillion height. In our opinion, conserving the length of hyaluronic acid chains results in dynamic fillers that may provide better results with lower risk of asymmetry compared with conventional products.


CONCLUSIONS: This new classification and associated treatment guideline aims to allow accurate assessment and enable practitioners to customize treatment for individual patients.

Is it possibile to define the ideal lips?

M. Kar, N. B. Muluk, S. A. Bafaqeeh, C. Cingi


ABSTRACT: The lips are an essential component of the symmetry and aesthetics of the face. Cosmetic surgery to modify the lips has recently gained in popularity, but the results are in some cases disasterous. In this review, we describe the features of the ideal lips for an individual's face. The features of the ideal lips with respect to facial anatomy, important anatomical landmarks of the face, the facial proportions of the lips and ethnic and sexual differences are described. The projection and relative sizes of the upper and lower lips are as significant to lip aesthetics as the proportion of the lips to the rest of the facial structure. Robust, pouty lips are considered to be sexually attractive by both males and females. Horizontal thirds and the golden ratio describe the proportions that contribute to the beauty and attractiveness of the lips. In young Caucasians, the ideal ratio of the vertical height of the upper lip to that of the lower lip is 1:1.6. Blacks, genetically, have a greater lip volume. The shape and volume of a person's lips are of great importance in the perception of beauty by humans. The appearance of the lips in part determines the attractiveness of a person's face. In females, fuller lips in relation to facial width as well as greater vermilion height are considered to be attractive.

Current concepts in lip augmentation

Gabrielle N. Mannino, Shari R. Lipner


ABSTRACT: Facial rejuvenation, particularly lip augmentation, has gained widespread popularity. An appreciation of perioral anatomy as well as the structural characteristics that define the aging face is critical to achieve optimal patient outcomes. Although techniques and technology evolve continuously, hyaluronic acid (HA) dermal fillers continue to dominate aesthetic practice. A combination approach including neurotoxin and volume restoration demonstrates superior results in select settings.

Male lip filler-aesthetic enhancement is not just limited to females: a case report

Anupriya Goel, Kritika Rai


BACKGROUND: Lips play an important role in facial aesthetics. Hyaluronic acid fillers have been widely used for lip augmentation in females but very few men seek this treatment due to the fear of feminization of lips. However, there are very few case reports published for correction of lips using fillers in men.


AIM: To assess the effectiveness of hyaluronic acid dermal fillers for enhancement of lips in males.


METHOD: A 52-year-old male underwent two sessions of treatment for inturned lips. In the first session, 2 ml hyaluronic acid dermal filler (Juvederm Ultra Plus-JUP) with 27G × 8 mm needle via bolus and retrograde linear thread technique was used. Assessment of lips was done after one week. Second session of treatment was done after 30 months of first treatment with 1 ml of filler.


RESULTS: Injection of filler not only led to a significant improvement in vermillion show, but also improved the overall facial appearance. The results of this treatment were long lasting and even after 30 months from the first treatment the patients' vermillion body still showed ten per cent improvement from the original.


CONCLUSION: Dermal lip filler treatment in men can be a very satisfying and rewarding procedure. Its awareness should be spread afar to increase its acceptability.

Hyaluronic acid injections to correct lips deformity following surgical removal of permanent implant

Raffaele Rauso, Francesco Federico, Nicola Zerbinati, Davide De Cicco, Giovanni Francesco Nicoletti, Gianpaolo Tartaro


ABSTRACT: One of the most attractive areas of the face are the lips, they are crucial for emotion and communication, both during animation and at rest. Throughout the years, several techniques to obtain permanent lip enhancement have been introduced, such as the use of nonresorbable fillers. The main problem related to permanent fillers is that undesirable results could not always be repaired; although lip sequelae can be addressed surgically, some surgeons will not perform this type of procedure due to its complexity and the lack of guidelines.In this paper, the authors present a case of a labial incompetence developed after lips implant removal performed elsewhere; after clinical examination the patient was planned for surgery, although during preoperative instrumental examination (chest X-ray) a solitary pulmonary nodule was noted; further investigation performed with needle biopsy revealed a lung cancer. For this reason, the surgical procedure planned for lip restoration was not performed; however, the patient asked for a minimally invasive procedure, thus to improve, although temporarily, her lips appearance.For the aforementioned reasons, the patient was treated just with hyaluronic acid injections achieving a pleasant result, solving also the labial incompetence at rest.To the best of the author's knowledge, this paper represents the first one describing the use of hyaluronic acid injections to restore lip competence following surgical removal of permanent implant.

Polyacrylamide gel 10 years experience: with particular reference to complications from filling of the body of the lip

Adam Rish


BACKGROUND: A review of 242 facial treatments, in 86 different patients, with polyacrylamide gel (PAAG) was carried out by the author between 2003 and 2013.


OBJECTIVES: To evaluate by retrospective study the long-term outcomes of PAAG filling for facial contouring. To quantify adverse events and patient comfort in prior mixing 0.3 mL of 2% lidocaine/1 mL PAAG and decanting into a smaller volume syringe.


METHOD: Review of clinical records combined with a patient survey.


COMPLICATIONS: 11 of 166 (6.6%) lip body infections; 1 of 202 (0.5%) in other sites. Addition of 2% lidocaine (55 treatments/28 patients) reduced lip body infections (8.7% to 5.7%, P < 0.05%) and mean pain score (8/10 to 2/10). No patients sustained any long-term side effects and all (even those infected) were eventually satisfied. Seven lip asymmetries, after infected PAAG drainage, were corrected with further PAAG, showing adverse events to be contamination rather than immune reaction.


CONCLUSION: Facial usage of PAAG with lidocaine results in high levels of patient satisfaction and low incidence of side effects (0.5%) except in the lip body (6.6%). Potential users, fearful of complications, may more readily use this cost-effective and long-lasting dermal filler if they avoid injection of the lip body.
