ABSTRACT
INTRODUCCIÓN: La Displasia Fibrosa Ósea Craneofacial es una lesión ósea benigna en la que se da una sustitución de tejido óseo normal por tejido fibro-óseo. Desarrollada a partir de una mutación genética. Subordinada en variantes: monostósica y polistósica. Escasos casos son reportados sobre malignización de la patología. El Diagnóstico se realiza con la sospecha clínica y se confirma mediante exámenes de imagen y anatomopatológicos. CASO CLÍNICO: El presente trabajo presenta una serie de tres casos diagnosticados de Displasia Osteofibrosa Craneofacial en el Hospital José Carrasco Arteaga y Hospital del Río, Cuenca-Ecuador, en los que por el cuadro clínico de los pacientes se decidió tratamiento quirúrgico. EVOLUCIÓN: En todos los casos, la evolución fue favorable. Se logró resultados positivos, reducción de síntomas y mejoría estética general en todos los casos. CONCLUSIÓN: Se obtienen mejores resultados con los tratamientos quirúrgicos actuales (remodelado más congelamiento óseo), entre ellos: buenos resultados estéticos, mejor calidad de vida, menor riesgo de infecciones. En el presente trabajo los tres participantes sometidos a resolución quirúrgica señalaron que el tratamiento reflejó positivamente en el ámbito funcional, estético y emocional. (au)
BACKGROUND: Craniofacial Bone Fibrous Dysplasia is a benign bone lesion where normal bone tissue is replaced with fibrous tissue. Developed from a genetic mutation. Subordinated in variants: monostotic and polyistotic. Few cases are reported on malignancy of the pathology. The diagnosis is determined with clinical suspicion and confirmed by imaging and pathology tests. CASE REPORT: In this paper, we present a series of three cases diagnosed with Craniofacial Fibrous Dysplasia at José Carrasco Arteaga Hospital and Hospital del Río, Cuenca-Ecuador. All of patients were treated with surgery, because of the clinical features. EVOLUTION: In all the cases, the patient evolution was favorable. Reduction of symptoms and general aesthetic improvement were achieved in all cases. CONCLUSION: Better results are obtained with the current surgical treatments (bone remodeling plus bone freezing), among them: good aesthetic results, better quality of life, lower risk of infections. In the present paper, the three patients treated with the surgical procedure indicated that the treatment reflected positively in the functional, aesthetic and emotional aspects.(au)

Fibrous dysplasia (FD) is part of a rare group of bone dysplasia. It exhibits benign behavior and can lead to osteolytic lesions, deformities, and fractures. The treatment is challenging, and accurate removal of the lesion is necessary to restore function and esthetics. Here we present two cases of FD where virtual planning with presurgical computed tomography (CT) was used for the production of a surgical guide for bone contouring. First, CT image reconstruction was performed to mirror the patient's original anatomy. Then, three surgical guides that determined the area and depth of bone wear were prepared and used in the relevant sequence during the actual surgeries, which were successfully performed in both patients. This technique is termed the template guide holes (TGH) technique. The findings from this report suggest that presurgical virtual planning and guide preparation allows direct and objective measurement of the level of bone wear and improves the functional and esthetic outcomes of surgery for FD. In particular, the TGH technique is safe and allows adequate preoperative surgical simulation, reduces the surgical duration, and increases the predictability of the final result.

INTRODUÇÃO: Dentre os tumores benignos do esqueleto craniofacial, a displasia fibrosa caracteriza-se pelo crescimento progressivo e acometimento de jovens, acarretando deformidade funcional e estética. Esse trabalho analisa aspectos clínicos e prognósticos de pacientes com essa patologia, submetidos a tratamento cirúrgico. MÉTODOS: Análise retrospectiva de 19 pacientes com displasia fibrosa craniofacial, acompanhados de janeiro de 1997 a dezembro de 2011, tratados com remodelamento ósseo e ressecção cirúrgica. Revisão da literatura sobre. RESULTADOS: A distribuição etária variou de 8 a 65 anos, com média de 21,75 anos. Dez pacientes (52,7%) eram do sexo feminino. A forma poliostótica predominou, com 15 casos (78,9%). Entre os ossos acometidos destacaram-se esfenóide, etmóide e frontal, nas formas poliostóticas; e maxila e zigoma, nas monostóticas. A principal queixa foi de assimetria da face. Um paciente evoluiu com diminuição de acuidade visual. O tratamento baseou-se na ressecção cirúrgica e reconstrução com enxerto, quando doença localizada, e no desgaste e remodelamento ósseo, em formas poliostóticas. Em apenas um caso (5,2%), com compressão de nervo óptico, foi necessário acesso intracraniano. Reabordagem cirúrgica, por crescimento tumoral, foi necessária em três pacientes. Como complicações, tivemos um caso de lagoftalmo e epicanto no pós-operatório de paciente tratado por cirurgia com acesso infraorbitário. Ausência de outras intercorrências no seguimento a curto e longo prazo. Os resultados de preservação de função e recuperação de contorno facial foram satisfatórios. CONCLUSÃO: Essa experiência, em concordância com a literatura, permite concluir que a cirurgia é eficaz na abordagem de casos selecionados de displasia fibrosa craniofacial.
INTRODUCTION: Fibrous dysplasia is benign tumor of the craniofacial skeleton that primarily affects young patients. It is characterized by the progressive growth of benign fibrous tumors with resulting functional and aesthetic deformities. This study assesses the clinical and prognostic features in patients with fibrous dysplasia who underwent surgical treatment at our institution. METHODS: Retrospective analysis of 19 patients with craniofacial fibrous dysplasia, treated between January 1997 and December 2011 with bone remodeling and surgical resection. We also review the literature regarding fibrous dysplasia. RESULTS: Patients ranged between 8-65 years old, with a mean age of 21.75 years. Ten patients (52.7%) were women. The polyostotic form was predominant and present in15 cases (78.9%). The sphenoid, ethmoid, and frontal bones were most commonly involved in the polyostotic form and the mandibular and zygomatic bones were most commonly involved in the monostotic form. The main complaint was asymmetry of the face. One patient developed decreased visual acuity. Treatment was based on surgical resection and graft reconstruction in the localized form of the disease, and bone abrasion and remodeling in the polyostotic form. Intracranial access was necessary in only one case (5.2%) where the optic nerve was compressed. Repeat surgical treatment due to recurrent tumor growth was necessary in three patients. The only complication occurred in a patient who developed lagophthalmos and epicanthus postoperatively after undergoing surgery using infraorbital access. No other complications occurred during short- and long-term follow-up. Functional preservation and facial contour recovery outcomes were satisfactory. CONCLUSION: Our experience, along with that of other investigators, demonstrates that surgery is effective in treating selected cases of craniofacial fibrous dysplasia.
