    Palpebral position interdependence in blepharoptosis: comparison of the effect of instillation of 10% phenylephrine drop and digital lifting
    (2014) PEREIRA, Ivana Cardoso; MATAYOSHI, Suzana
    Purpose: To quantify and compare the effects of instillation with 10% phenylephrine and digital lifting on the contralateral upper eyelid of patients with involutional bilateral blepharoptosis. Methods: The present prospective clinical study involved patients with involutional bilateral blepharoptosis who underwent two tests: 1) digital lifting of the more ptotic eyelid and observation of the effect on the contralateral eyelid and 2) instillation of two drops of 10% phenylephrine in the more ptotic eye and observation of the effect on the contralateral eyelid. Patients were filmed before and 5, 10, and 15 min after instillation, and the resulting images were analyzed to obtain eyelid measurements. The results were tested using a linear mixed-effects model. Results: A total of 27 patients, ranging from 52 to 82 years of age (mean age 68.51 +/- 8.21 years), 24 (88.88%) of whom were women, were included in the present study. In eyes that received instillation, the marginal distance reflex-1 (MDR1) values increased from baseline (1.21 +/- 0.60 mm) until 10 min after instillation, then remained statistically unchanged until 15 min after instillation (2.42 +/- 0.90 mm). Significant differences were observed in the contralateral eye of the group that underwent digital lifting (1.51 +/- 0.53 mm - 1.63 +/- 0.56 mm) and in the contralateral eye of the group that underwent 10% phenylephrine instillation (1.38 +/- 0.54 mm - 1.63 +/- 0.56 mm); p=0.02 and p<0.01, respectively. Conclusions: In all eyes, 10% phenylephrine elevated the upper eyelid, with improved eyelid height at 10 min after instillation. Significant differences were observed in the height of the contralateral eyelid when compared before and after each intervention in each group; however, this difference was very small and nearly undetectable by conventional clinical evaluation in the digital lifting group. However, the 10% phenylephrine eye-drop test resulted in substantial changes in MDR1 values in the treated and contralateral eyes, indicating clinical and statistical efficiency.

    Periocular basal cell carcinoma: cost of topical immunotherapy versus estimated cost of surgical treatment
    (2012) MACEDO, Erick Marcet Santiago de; CARNEIRO, Rachel Camargo; CARRICONDO, Pedro Carlos; MATAYOSHI, Suzana
    Purpose: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. Methods: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of Sao Paulo (HC-FMUSP, Brazil). The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. Results: Immunotherapy lasted from 8 to 12 weeks. All patients reported each cold-stored sachet with 5% imiquimod cream lasted 3 days. According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.40-1,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. Conclusions: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns. The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions. Further studies should evaluate the possibility of institutions equating the cost of immunotherapy and surgical treatment by acquiring similar but less expensive medications.

    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, Suzana
    ABSTRACT 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
    ABSTRACT 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, Suzana
    Purpose: 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.

    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, Suzana
    Abstract 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.
