- ItemAcesso aberto (Open Access)Aberrações ópticas de alta ordem em pacientes com distonias faciais tratados com toxina botulínica(Conselho Brasileiro de Oftalmologia, 2011-12-01) Yabiku, Mariann Midori [UNIFESP]; Sartori, Juliana De Filippi [UNIFESP]; Sarraff, Eduardo Pantaleão [UNIFESP]; Osaki, Tammy Hentona [UNIFESP]; Hossaka, Sidarta Keizo [UNIFESP]; Pereira, Carolina Isolane [UNIFESP]; Freitas, Wilson De [UNIFESP]; Osaki, Midori Hentona [UNIFESP]; Cariello, Angelino Julio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To analyze the ocular wavefront aberrations in patients with facial dystonia treated with botulinum toxin A. METHODS: Patients with benign essential blepharospasm and hemifacial spasm in activity underwent slit lamp examination and bilateral wavefront analysis under pharmacologic mydriasis using Alcon LADARvision® wavefront aberrometry system. After that, all patients were treated with botulinum toxin A injections performed by the same ophthalmologist. After one month, the wavefront analysis was performed in the same way and by the same examiner. The main outcome measure was the change in ocular wavefront aberrations. Paired T-test was used to compare pre and post-injection numeric wavefront values. RESULTS: From a total of 11 patients enrolled in this study, 6 (54.5%) had essential blepharospasm and 5 (45.5%) had hemifacial spasm. The fellow eyes of patients with hemifacial spasm were not included, totalizing 17 eyes with spasm. Eight patients were female (72.7%) and three were male (27.3%), the male:female ratio was 1:2.6. The age ranged from 50 to 72 years old with a mean of 65.9 ± 8.2 years. The mean of high order root mean square (RMS) wavefront aberrations was 0.68 before and 0.63 one month after the treatment (p=0.01). Before the treatment, the mean of spherical aberration was 0.23 and decreased to 0.17 one month after the treatment (p=0.01). There was no significant difference in the other higher-order aberrations before and after the treatment (p>0.05). CONCLUSION: The treatment with botulium toxin may decrease spherical aberrations in patients with facial dystonia.
- ItemAcesso aberto (Open Access)Estudo anatômico do músculo levantador do lábio superior(Associação Médica Brasileira, 1997-09-01) Ferreira, Lydia Masako [UNIFESP]; Minami, E. [UNIFESP]; Pereira, M.d. [UNIFESP]; Chohfi, L.m.b. [UNIFESP]; Andrews, J. de M. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The authors describe the anatomical characteristics of the levator labii superioris muscle by dissection in cadavers. PURPOSE. We describe the characteristics of these muscle, the details and relations, hopefully contributing to the study of muscle of the face. METHODS. Twenty faces of cadavers were dissected. The following features were studied: origin, insertion, length, width, thickness, relations, innervation and blood supply. RESULTS. In all cases the muscle originated from the inferior orbital margin. Two insertions were observed: via lateral fibers, superficial to the orbicularis oris muscle and via deep fibers thar form part of the raphe at the corner of the mouth (70%); via superficial fibers to the orbicularis oris muscle (30%). The average of the length was 24.66mm and the average of the thickness was 3.57mm. The width at its insertion was 11,2 mm, and at the origin was 15.96mm. The levator labii superioris muscle was found to be anterior to the levator anguli oris; it was posterior to the distal portion of the zygomaticus minor (90%) and posterior to the mid portion of the zygomaticus minor (10%). The innervation was from the inferior branch of the zygomatic nerve (facial nerve) and from the infraorbital nerve (trigeminal nerve). The inferior portion of the muscle is supplied by branches of the angular artery and the superior part from branches of the infraorbital artery.
- ItemAcesso aberto (Open Access)Reconstrução total de lábio superior e columela com retalho musculocutâneo em ilha do depressor do ângulo da boca(Associação Médica Brasileira, 1997-06-01) Sabino Neto, Miguel [UNIFESP]; Castilho, Helton Traber de [UNIFESP]; Garcia, Elvio Bueno [UNIFESP]; Ferreira, Lydia Masako [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Case report of a man that had been previously submitted to many resections of facial skin carcinomas. A serious deformity on the upper lip and columella remains. A total upper lip and columella reconstruction through the depressor anguli oris myocutaneous island flap is described.
- ItemSomente MetadadadosRetalho músculo-cutâneo em ilha do depressor do ângulo da boca(Universidade Federal de São Paulo (UNIFESP), 1997) Sabino Neto, Miguel [UNIFESP]; Ferreira, Lydia Masako [UNIFESP]; Universidade Federal de São Paulo [UNIFESP]Foram tratados 20 pacientes, 19 com carcinoma de labio e 1 com deformidade cicatricial de labio superior. Em todos os casos a reparacao foi realizada atraves do retalho musculo-cutaneo em ilha do depressor do angulo da boca. 13 pacientes eram do sexo masculino e 7 do sexo feminino, sendo 19 brancos e 1 nao branco. Dos 19 pacientes com carcinoma de labio, 14 apresentavam carcinoma basocelular de labio superior e 5 carcinoma espinocelular de labio inferior. O retalho foi confeccionado com ilha cutanea com maior eixo no sentido horizontal em 14 pacientes e no sentido vertical em 6 pacientes. Em 19 casos somente um dos musculos foi utilizado, e no paciente com deformidade cicatricial o retalho foi realizado com os dois musculos em seu pediculo. Este procedimento possibilitou a transferencia de ilha cutanea suficiente para a reparacao de todo o labio superior e columela. Os resultados quanto a funcao no periodo tardio foram SATISFATORIOS em todos os casos. Quanto a vitalidade no periodo imediato e tardio, o resultado foi SATISFATORIO em 19 dos pacientes e NAO SATISFATORIO em 1 paciente ( este apresentou necrose cutanea de 30% do retalho). Todos os casos tiveram resultado estetico no periodo tardio considerado SATISFATORIO, e apresentavam sensibilidade dolorosa restabelecida neste periodo. Concluiu-se que o retalho musculo-cutaneo em ilha do depressor do angulo da boca pode ser utilizado, com seguranca, em reparacoes de labio inferior e superior com bons resultados estetico e funcional
