Patients are seeking healthier lives, and at the same time their concern about having a beautiful face and maintaining a youthful appearance over time has increased. Traditionally, surgeries based on tissue resection and resurfacing were the focus in facial rejuvenation. Over the last decade, minimally invasive procedures have expanded exponentially because of the variety of cosmetic products available on the market and because patients are looking for a better appearance with nonincision methods. The understanding of the aging process, facial anatomy, and ideal proportions is extremely important for successful rejuvenation procedures. Also, neuromodulators, chemical peels, filler properties, correct indications, and effectiveness must be well known by the injector for favorable results. Therefore, knowledge of all facial cosmetic options and an adequate facial analysis are essential for a better performance. In this article, the authors review some different product options and show cases of minimally invasive cosmetic procedures for the face currently used.

INTRODUCTION: The esthetic balance of the face results from harmonic and symmetrical facial proportions. The literature describes several methods for lower-third facial analysis, but lacks a simple and practical method. OBJECTIVE: To review the methods of analysis of the ideal projections of the chin based on soft tissues, showing the advantages and disadvantages of each. METHODS: Literature review through the PubMed database. RESULTS: The following methods for chin analysis based on soft tissues were reviewed: Gonzalles-Ulloa, Goode, Merrifield, Silver, Legan, Gibson & Calhoun, cervicomentual angle, and mentocervical angle. CONCLUSION: An adequate analysis of the proportions of the face and facial disharmony is essential for the correct indication of the necessary procedures and good surgical outcome. The authors propose an algorithm to facilitate the indication for chin augmentation surgery. Resumo Introdução: O equilíbrio estético da face resulta de proporções faciais harmônicas e simétricas. A literatura descreve vários métodos de análise do terço inferior da face, mas carece de um método simples e prático. Objetivo: Revisar os métodos de análise da projeção ideal do mento baseadas em tecidos moles, mostrando as vantagens e desvantagens de cada um. Método: Revisão da literatura através da base de dados Pubmed. Resultados: Os seguintes métodos para análise do mento baseada em partes moles são revisados: Gonzalles-Ulloa, Goode, Merrifield, Silver, Legan, Gibson & Calhoun, ângulo cervicomentual e ângulo mentocervical. Conclusão: A análise adequada das proporções da face e desarmonia facial faz-se essencial para a correta indicação dos procedimentos necessários e bom resultado cirúrgico. Propomos um algoritmo para facilitar indicação de avanço de mento.

A 15-YEAR-OLD GIRL PRESENTED WITH A 2-week history of progressive facial palsy on the right side. No other otologic symptoms were identified. Physical examination revealed only a facial palsy, which was classified as House-Brackmann scale grade V. There were no signs of involvement of other cranial nerves. The findings of otoscopy and palpation of the parotid gland were normal. Audiometry showed a normal hearing threshold and an absent stapedial reflex in the right ear. The patient was treated with oral dexamethasone acetate and acyclovir, with no clinical improvement. A reformatted coronal computed tomogram (Figure 1), axial (Figure 2) and coronal (Figure 3) enhanced T1-weighted magnetic resonance images (MRIs), and a coronal T2-weighted MRI (Figure4) were obtained.
