- Procedimentos cirúrgicos e não cirúrgicos para elevação das sobrancelhas: revisão sistemática e fluxograma de abordagem(2019) MIRANDA, RICARDO EUSTACHIO DE; MATAYOSHI, SUZANAABSTRACT Introduction: To review the medical literature regarding the surgical and non-surgical treatments of eyebrow ptosis and to present a decision flowchart for eyebrow lift. Methods: A systematic review of the literature available was held in PUBMED following inclusion and exclusion criteria. A flowchart was elaborated to systematize the approach to eyebrow ptosis based on the experience of the authors. Results: Several articles were included describing a variety of surgical and non-surgical correction techniques for eyebrow ptosis. The most common surgical approaches were internal eyebrow elevation, direct elevation, temporal elevation, and coronal/pretrichial/endoscopic rhytidoplasty. The non-surgical approaches found were botulinum toxin injections, fillers, and fixation threads. Conclusion: There are several surgical and non-surgical procedures described in the literature for lifting of the eyebrow, demonstrating that there is no ideal method for all patients. The use of a flowchart can help carry out a systematic and personalized approach according to the characteristics of each patient.
- Avoiding Complications on the Upper Face Treatment With Botulinum Toxin: A Practical Guide(2022) BORBA, Andre; MATAYOSHI, Suzana; RODRIGUES, MatheusBackground Currently, botulinum toxin (BoNT) injections are the most commonly performed non-invasive procedure for rejuvenation on the upper face. The therapeutic use of botulinum toxin has generally been safe and well tolerated. Adverse effects are considered mild, transient, and self-limited. However, as with all other injectable procedures, this one is also susceptible to adverse events and complications. When the safety zones are respected, the chance of any of these complications is practically null. Thus, this review aims to describe the main complications of treatment with BoNT on the upper face and to present a practical guide based on current evidence on how to avoid them. Methods The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. Results The main complications secondary to BoNT injections on the upper face are: ptosis of eyelid or eyebrow, eyebrow asymmetry, diplopia, Lakeophthalmos, Palpebral ectropion, and prominence of the palpebral bags. To avoid such complications, it is necessary to have knowledge of the anatomy of this region and adequate and individualized planning based on the existing patterns of the frontalis muscle, glabella, and crow's feet. This review presents the specificities of each of these regions and practical suggestions to obtain satisfactory results, avoiding complications. Conclusion Particularly on the upper face treatment with BoNT offers predictable results, has few adverse effects, and is associated with high patient satisfaction. However, it is suggested that the commented parameters and safety areas be incorporated into daily practice so that the possibilities of complications are minimized as much as possible.
- Visual loss after aesthetic facial filler injection: a literature review on an ophthalmologic issue(2022) KATO, Juliana Mika; MATAYOSHI, SuzanaDermal filler injection is among facial rejuvenation treatments that have been increasingly used. Despite being a minimally invasive procedure, it can lead to severe complications such as blindness. A review of all cases of filler-induced visual loss in the world literature was conducted to summarize the mechanisms, anatomical considerations, and clinical ophthalmologic course, current strategies of prevention and management, and trends over the years. We identified 233 cases of filler-induced visual loss, and 172 patients had a severe visual impairment in at least one eye. The typical patients are young women who received injections of hyaluronic acid or autologous fat in the glabella or nose, and the typical presentations were sudden ocular pain, ptosis, and ophthalmoplegia due to vascular occlusion. The findings of this study also suggest an increase in the number of unlicensed professionals performing the procedure. Even though the continued development of dermal fillers has improved the treatment options available, further studies and strategies are necessary to reduce the incidence and minimize the consequences of filler-induced visual loss.
- Teleophthalmology: where are we now?(2017) GRISOLIA, Ana Beatriz D.; ABALEM, Maria Fernanda; LU, Yan; AOKI, Lisia; MATAYOSHI, SuzanaInformation and communication technology has rapidly reached diverse aspects of modern life, including medicine and health-related matters. Aiming to improve teaching, research, and health care delivery for geographic or economic reasons, telemedicine is an ascending trend. Teleophthalmology might be one of the most challenging applications of telemedicine given its need for standardized and high definition digital images. However, technological advances are enhancing information transmission continuously and expanding the potential of teleophthalmology. In this review, we investigate the evolution and current status of teleophthalmology, describe its use in different areas, and explore its applicability. Although teleophthalmology is not a replacement for traditional eye care and still faces challenges for adequate implementation, it represents an effective care delivery method, facilitating appropriate and timely distribution of service especially in remote and/or underdeveloped regions.
- Obstrução lacrimal pós-tratamento oncológico: revisão de literatura(2022) SILVA, Camilla Duarte; FONSECA, Fabricio Lopes da; KATO, Juliana Mika; MATAYOSHI, SuzanaABSTRACT Lacrimal duct obstruction can be a side effect of systemic and/or local cancer treatments. Chronic epiphora has a great impact on the quality of life of oncological patients. Since terminal fibrosis of the lacrimal system may require complex procedures, it is important to be aware of this adverse effect in order to recognize and treat it, or even prevent it. A literature review was performed to identify all types of systemic cancer treatment associated with lacrimal obstruction and to describe the mechanisms, frequency, treatment, and prophylaxis. The oncological treatments associated with lacrimal obstruction were head and neck radiotherapy (dosage above 45-75 Gy), radioiodine therapy (dosage above 150 mCi), and chemotherapy with 5-FU, S-1, Capecitabine and Docetaxel. Depending on the dose, this complication may be irreversible. Prophylactic intubation of the lacrimal system is an option for prophylaxis in cases of radiotherapy, use of 5-FU, S-1, and Docetaxel. Final surgical treatment is dacryocystorhinostomy.
- Uso da estereofotogrametria para mensuração do volume da anatomia externa da face: revisão sistemática(2018) MIRANDA, RICARDO EUSTACHIO DE; MATAYOSHI, SUZANA; BRABO, JANAINA LUCILA; MIYOSHI, LETÍCIA HARUMIABSTRACT Introduction: Photographic documentation is important in several medical specialties, such as plastic surgery. Two-dimensional photography has limitations in capturing structure depth and volume, requiring other instruments to evaluate these changes. Several technologies have been developed for three-dimensional analysis of objects, of which stereophotogrammetry uses computerized analysis of two or more simultaneous photographs of the object to produce a three-dimensional geometric model. The advantages of stereophotogrammetry include lower cost, portability, absence of radiation, and speed of image capture. The aim of the present study was to perform a bibliographic review evaluating the use and accuracy of stereophotogrammetry for measuring the volume of facial structures. Methods: Using a combination of MeSH keywords and free terms, a search was performed in the Cochrane Library and MEDLINE databases. The search included all articles published on or before May 2018. Results: 2,213 studies were initially retrieved using this search strategy. Of these, 27 studies were selected based on the eligibility criteria, of which 21 were non-randomized case studies and 6 were randomized clinical trials. The methodological quality of the studies varied between 50 and 67%, on a grading scale from 0 to 100%. Conclusions: Stereophotogrammetry is a promising technology that is increasingly being used to check for facial volume variations with high accuracy and reproducibility. More studies with higher methodological quality are needed for evaluating the accuracy and use of stereophotogrammetry for facial volume evaluations.
- Non-surgical treatment for eyelid retraction in thyroid eye disease (TED)(2018) GRISOLIA, Ana Beatriz Diniz; COUSO, Ricardo Christopher; MATAYOSHI, Suzana; DOUGLAS, Raymond S.; BRICENO, Cesar AugustoThyroid eye disease (TED) is an autoimmune condition with an unpredictable course that may lead to permanent facial disfigurement. Eyelid retraction is one of the most common findings, and frequently demands attention due to ocular exposure and impaired cosmesis. Surgical treatment remains the most effective option, but there is a role for temporary corrections during the active phase of the disease, as well as in patients who are poor surgical candidates. The aim of this review is to describe the non-surgical modalities currently available for treatment of eyelid malposition in TED. The authors have focused on the use of hyaluronic acid, triamcinolone injections and botulinum toxin type A as non-surgical treatment alternatives, paying special attention to dosing, technique, efficacy and duration of effect. Non-surgical treatment modalities may represent viable in cases where surgical correction is not an option. Although temporary, these modalities appear to be beneficial for ocular exposure remediation, improving quality of life and broadening our therapeutic arsenal.
