- Efficacy of mitomycin C in modified transcanalicular diode laser dacryocystorhinostomy(2022) FEIJÓ, Eduardo Damous; DIAS, Mirna de Melo; SOUZA, Bruna Angelina Alves de; CAIXETA, Juliana Alves; LIMONGI, Roberto Murillo; MATAYOSHI, SuzanaABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.
- 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.
- Reconstrução total de pálpebra superior no tratamento do carcinoma de glândula sebácea(2020) VERAS, Deborah de Oliveira; GUMIERO, Mariana Pereira Leite Dias; BAPTISTA, Mariana Nóbrega Meireles; MATAYOSHI, SuzanaAbstract Sebaceous gland carcinoma (SGC) is the third most frequent malignant neoplasm in the eyelids. It usually affects elderly women and can simulate blepharitis or chalazion. Upper eyelid reconstruction is always challenging. The purpose of this is to report an unusual case of SGC in the upper eyelid of a young and male patient. Total resection of the right upper eyelid was performed and histological examination revealed free margins. The reconstruction was done with two surgical procedures at different times. Due to the fact that SGC presents a high potential for metastasis, the patient continues to be followed for functional and aesthetic reevaluation.
- O uso de enxerto e retalho de periósteo em Oftalmologia(2019) BACCEGA, Felipe; MATAYOSHI, Suzana; NASCIMENTO, Maria Antonieta da Anunciação GinguerraAbstract Purpose: The authors reviewed the periosteum use in ophthalmic surgery and its results. Methods: A comprehensive review of the literature using Google Scholar, PubMed and SciElo databases with all articles about the periosteum use in Ophthalmology published from 1977 to 2018. Results: A total of 21 studies followed the review's purpose: 9 case reports, 9 case series, 1 retrospective cohort and 2 prospective cohorts. 206 patients were submitted to the procedures with the periosteum use in the two main forms: graft and flap. The principal reasons for periosteal use were: orbital implant covering and eyelid reconstruction. Surgical outcomes were very satisfactory with low complication rates of 10.67% and minimal necessity of new surgical intervention of 2.42%. Conclusion: The periosteum use in Ophtalmology is a promising technique with good results so far and should always be a therapeutic option for the ophthalmologist. However, based on available data in the literature, more studies with statistical power for knowledge sedimentation in this subject are recommended.
- Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis(2018) FEIJÓ, Eduardo Damous; ALMEIDA, Adriana Ribeiro de; MATAYOSHI, SuzanaAbstract We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin's Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.
- 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.
- Lagoftalmo na hanseníase: experiência clínica em centro de referência amazonense(2021) BENTES, Gilson Lima; MATAYOSHI, Suzana; TALHARI, CarolinaABSTRACT Objective: The present study aimed to characterize the epidemiological and clinical profile of patients with lagophthalmos associated with leprosy, seen at the ophthalmology outpatient clinic of Fundação Alfredo da Matta, Manaus, Amazonas. Methods: This is a retrospective study carried out by analyzing the medical records of the patients included in the study. Sex, age, clinical form, degree of disability in diagnosis and outcome were obtained from medical records. Onset, type of impairment (unilateral or bilateral), degree of intensity of lagophthalmos and associated eye changes were also compiled. Results: 65 patients were included; 66.1% were male and 53.8% were older than 60 years. Regarding the operational classification of leprosy, most patients (81.5%) were multibacillary: 33.8% in the form of borderline leprosy and 47% virchowian. 36.9% of cases had ocular sequelae associated with lagophthalmos: corneal opacity, epiphora, band keratopathy, and corneal neovascularization.41.6% progressed to blindness. Lagophthalmos was performed clinically in 23 patients and the surgical approach was indicated in 42. Regarding surgical treatment, it consisted mainly of gold weight implantation and Tessier's canthoplasty. Discussion: Lagophthalmos in this sample affected more elderly men, was related to the multibacillary form, with leprosy-like leprosy as reported in the literature. The diagnosis of lagophthalmos was delayed in most cases, explaining the large number of sequelae including blindness. Conclusion: The present study reinforces the need for early eye care so that the potential and serious sequelae associated with this condition are avoided.
- Spectrum approach to congenital ectropion(2022) GONÇALVES, Allan Christian Pieroni; YOSHIDA, Marcel Nakae; LEITE, Lívio Viana de Oliveira; FEIJÓ, Eduardo Damous; LIMONGI, Roberto Murillo; MATAYOSHI, SuzanaABSTRACT In the literature, there is a confusing classification among congenital floppy eyelid, eyelid eversion and ectropion. They are described as eyelid malposition with laxity and out-turning of the eyelids in newborns, usually associated with conjunctival prolapse and chemosis. Although the underlying pathophysiology of these rare conditions is obscure, they share anatomic characteristics. Thus, instead of a plethora of denominations, a spectrum approach should join these entities. In this paper, the authors present a case series of four patients that illustrates distinctive presentations of this condition and advocate that it should be considered as variants of a spectrum of congenital ectropion. Mild cases, when promptly treated, can benefit from clinical treatment. On the other hand, severe and delayed cases will need surgical correction as in the case of acquired ectropion.
- Fogo em campo cirúrgico - Medidas preventivas para cirurgia palpebral segura(2020) STUCHI, Daniella de Paiva Almeida; CHEBLE, Camila; MATAYOSHI, SuzanaAbstract Fire in the surgical field during eyelid surgery is an intra-operative complication that is dramatic for both the patient and the medical staff. It’s being reported a case of surgical accident during eyelid surgery where the patient suffered a brow burn. There was interaction between the oxygen used for sedation (open mask) and a source of ignition represented by monopolar cautery. Although the patient presented good clinical evolution with complete recovery of the cutaneous lesion, this case is an alert to avoid such type of occurrence. This work highlights the conditions involved and the way of prevention.
- 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.
