ABSTRACT
O odontoma é uma alteração definida como um tumor odontogênico benigno e representa cerca de 70% das ocorrências dos tumores odontogênicos. O objetivo desse estudo foi apresentar um caso clínico referente ao diagnóstico e tratamento de um odontoma complexo em região anterior de maxila. Paciente de 27 anos compareceu à clínica buscando avaliação de rotina e, ao exame clínico, foi verificada a ausência dos elementos dentais 13 e 14 e retenção prolongada do 54. Radiograficamente, foi observada a presença de uma lesão radiopaca sugestiva de odontoma complexo, além de impactação dos elementos dentais 13 e 14. A abordagem adotada foi a remoção da lesão, do elemento 54 e tracionamento ortodôntico do elemento 13. A cirurgia foi feita em ambiente ambulatorial, sob anestesia local, iniciando pela exodontia do elemento 54, logo depois foi feita a incisão de Newman, descolamento mucoperiostal e remoção da lesão com broca cirúrgica esférica em alta rotação, sob refrigeração abundante com soro fisiológico estéril. Posteriormente, foi acessado o elemento 13 por vestibular e feito o desgaste ósseo com broca cirúrgica esférica, até a exposição da coroa do dente. Por fim, foi realizada a colagem do dispositivo de tracionamento ortodôntico, botão associado a fio de aço colocado com resina composta e o paciente foi encaminhado ao ortodontista. O diagnóstico e tratamento desse tipo de patologia é de suma importância, evitando implicações estéticas e funcionais ao paciente. Não é comum recorrências, e tem prognóstico excelente... (AU)
Odontoma is an alteration defined as a benign odontogenic tumor and represents about 70% of the oc currences of odontogenic tumors. The aim of this study was to present a clinical case regarding the diag nosis and treatment of a complex odontoma in the anterior region of the maxilla. A 27-year-old patient came to the clinic seeking routine evaluation and, on clinical examination, the absence of dental elements 13 and 14 and prolonged retention of 54 were verified. Radiographically, the presence of a radiopaque lesion suggestive of a complex odontomawas observed, in addition to impaction of dental elements 13 and 14. The approach adopted was the removal of the lesion, element 54 and orthodontic traction of element 13. The surgery was performed in an outpatient setting, under local anesthesia, starting with the extraction of element 54, shortly afterwards Newman's incision, mucoperiosteal detachment and removal of the lesion with a high-speed spherical surgical drill, under abundant refrigeration with sterile saline. Subsequently, element 13 was accessed through the vestibular and bone wear was done with a spherical surgical drill, until the tooth crown was exposed. Finally, the orthodontic traction device was bonded, a button associated with steel wire placed with composite resin and the patient was referred to the ortho dontist. The diagnosis and treatment of this type of pathology is extremely important, avoiding aesthetic and functional implications for the patient. Recurrences are not common and have an excellent prognosis... (AU)

OBJECTIVE: To compare the effects of hydrophobic and hydrophilic materials in square-edged acrylic intraocular lenses (IOLs) on the development of posterior capsule opacification (PCO) after pediatric cataract surgery. METHODS: Patients were randomly assigned to group 1 (hydrophobic acrylic square-edged IOLs; 13 eyes) or group 2 (hydrophilic acrylic square-edged IOLs; 13 eyes). The study evaluated PCO rates using Evaluation of Posterior Capsule Opacification (EPCO) 2000 software at one, three, six and 12 months postoperatively. Postoperative measurements also included corrected distance visual acuity (CDVA), neodymium:yttrium‐aluminum‐garnet (Nd:YAG) capsulotomy and postoperative complications other than PCO. RESULTS: Both groups had significant increases in PCO rates after one year. Comparison of the groups showed no significant differences in the EPCO scores at three (group 1, 0.007±0.016 vs group 2, 0.008±0.014; p=0.830), six (group 1, 0.062±0.103 vs group 2, 0.021±0.023; p=0.184), or twelve months postoperatively (group 1, 0.200±0.193 vs group 2, 0.192±0.138; p=0.902). We also found no significant group differences regarding the change (delta, Δ) in EPCO scores between three and six months (group 1, 0.055±0.09 vs group 2, 0.013±0.02; p=0.113) or between six and twelve months postoperatively (group 1, 0.139±0.14 vs group 2, 0.171±0.14; p=0.567). Twenty-three percent of patients required Nd:YAG capsulotomy at the twelve-month visit. CONCLUSIONS: No differences in PCO rates were found between hydrophobic and hydrophilic acrylic square-edged IOLs in children between five and twelve years of age at one year of follow-up.

ABSTRACT Intraoperative and postoperative cataract surgery in eyes with anterior megalophthalmos are challenging procedures. Herein we describe the case of a 53-year-old male with anterior megalophthalmos who developed unilateral Urrets-Zavalia Syndrome following cataract surgery.
RESUMO O intraoperatório e o pós-operatório de cirurgia de catarata em olhos com megaloftalmo anterior é desafiador. Descrevemos o caso de um homem de 53 anos com megaloftalmo anterior que desenvolveu a Síndrome de Urrets-Zavalia unilateral após cirurgia de catarata.
