- 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.
- Relationship between actinic keratosis and malignant skin lesions on the eyelid(2023) ROSSATO, Luiz Angelo; CARNEIRO, Rachel Camargo; MACEDO, Erick Marcet Santiago de; LIMA, Patricia Picciarelli de; URBANO, Mariana Ragassi; MATAYOSHI, SuzanaPurpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.
- Profile of patients with essential blepharospasm and hemifacial spasm in the two largest ophthalmology reference centers in Brazil(2024) FOWLER, Flavio A.; YABUMOTO, Cristina; OSAKI, Midori H.; GAMEIRO, Gustavo R.; BRABO, Janaina L.; MATAYOSHI, Suzana; MARINHO, Regina C. R. S.; OSAKI, Tammy H.Purpose: Information is scarce regarding the comprehensive profile of patients with essential blepharospasm and hemifacial spasm in Brazil. The present study aimed to assess the clinical features of patients with these conditions, followed up in two reference centers in Brazil. Methods: The study included patients with essential blepharospasm and hemifacial spasm, followed up at the Departments of Ophthal- mology at Universidade Federal de Sao Paulo and Universidade de Sao Paulo. Apart from demographic and clinical features, past stressful events related to the first symptoms (triggering event), aggravating factors, sensory tricks, and other amelio- rating factors for the eyelid spasms were assessed.Results: A total of 102 patients were included in this study. Most patients were female (67.7%). Essential blepharospasm was the most frequent movement disorder [51/102 patients (50%)], followed by hemifacial spasm (45%) and Meige's syndrome (5%). In 63.5% of the patients, the onset of the disorder was associated with a past stressful event. Ameliorating factors were reported by 76.5% of patients; 47% of patients reported sensory tricks. In addition, 87% of the patients reported the presence of an aggravating factor for the spasms; stress (51%) was the most frequent. Conclusion: Our study provides infor- mation regarding the clinical features of patients treated in the two largest ophthalmology reference centers in Brazil.
- Smartphone and custom-made software to assess the effect of botulinum toxin in essential blepharospasm: Initial results(2023) YABUMOTO, Cristina; OSAKI, Midori H. H.; GAMEIRO, Gustavo R. R.; MATAYOSHI, Suzana; CAMPOS, Mauro; OSAKI, Tammy H. H.Background and purpose: It is challenging to assess essential blepharospasm (EB) pa- tients objectively because they exhibit chaotic patterns of abnormal eyelid movements. Previously employed objective approaches used systems with low levels of accuracy sys-tems or were too complex to be applied in routine clinical practice. We aimed to develop a practical tool using a smartphone camera and custom -made software to objectively assess the therapeutic effects of botulinum toxin in blepharospasm patients. Methods: Thirty- four patients with EB were evaluated before and 15 days after receiv- ing onabotulinumtoxinA injections. The control group was composed of 19 age-matched healthy individuals. A smartphone (iPhone 6 S; Apple) was used to record spontaneous eyelid movements for 3 min, after which eyelid movement frequency was analysed using custom-made software.Results: Before treatment, eyelid movement frequency was significantly higher in the EB group (21.55 +/- 13.30 movements/min) compared to the control group (8.26 +/- 8.89 eyelid movements/min; p < 0.001). The frequency of spontaneous eyelid movements was sig- nificantly reduced after treatment in the EB patients (8.46 +/- 6.32 eyelid movements/min; p < 0.001). After treatment, no statistically significant difference in eyelid movement rate was observed between the EB patients and the control group (p = 0.32).Conclusions: Assessment of the spontaneous eyelid movements obtained with the smartphone camera and analysed with the custom -made software enabled us to objec-tively measure the therapeutic effects of botulinum toxin in patients with blepharos-pasm. Further refinement of this system could enable customized and fine adjustments to botulinum toxin doses based on each patient's needs.
- Dacryoendoscopic recanalization of lacrimal passage obstruction/stenosis after radioiodine therapy for differentiated thyroid carcinoma(2022) INOMATA, D.; HOSHI, S.; ALCâNTARA, C. P. B. C.; HIRAOKA, T.; TASAKI, K.; OSHIKA, T.; MATAYOSHI, S.Purpose: Radioiodine therapy, a standard treatment for differentiated thyroid carcinomas, is associated with several adverse events including lacrimal drainage system obstruction. Herein, we describe the first case of duct lumen recanalization using dacryoendoscopy for lacrimal passage obstruction and stenosis after radioiodine therapy. Observations: A 48-year-old female treated with radioiodine therapy for differentiated thyroid carcinoma 5 years prior presented with epiphora in both eyes. Dacryocystography showed nasolacrimal duct stenosis in the right eye and nasolacrimal duct obstruction in the left eye. Dacryoendoscopic examination revealed right common canalicular polyps, fibrosis in the right lacrimal sac, right nasolacrimal duct stenosis, and left upper and common canaliculus stenosis. Lacrimal passage recanalization with the insertion of a nasolacrimal stent tube using dacryoendoscopy was performed on the right eye. This successfully resolved the epiphora. Conclusions and importance: Dacryoendoscopic examination for epiphora after radioiodine therapy may help detect early-stage nasolacrimal passage obstruction/stenosis. This condition can be resolved by recanalization and insertion of a lacrimal tube, without the need for a more invasive surgical approach such as dacryocystorhinostomy. © 2022 The Authors
