ABSTRACT
ABSTRACT: This study aimed to describe the conservative surgical management of odontogenic keratocyst, comparing with clinical and demographic findings in the literature, based on a literature review, using the quality criteria established in the literature for clinical cases and case series. We searched for cases of keratocysts published in four databases. We selected cases of patients followed up at least one year after sugical treatment. We described the case of a patient who was asymptomatic, and the lesion was detected by routine radiographic examination. At the same surgical time, we enucleated the lesion, followed by curettage and drain installation. Currently, there are no signs of disease recurrence. We followed the CARE guidelines (Case Report Guidelines), in this report. Literature review disclosed 27 cases. Keratocyst was frequent in male-adult patients, and the mean follow-up time after surgery was 46.7 ± 28.1 months. The main clinical findings such as association with teeth, location, extension of lesion, and radiographic pattern corroborate the classic pattern of described cases reported by literature with a low general rate of recurrences. In conclusion, conservative treatment was successful for the clinical case described, over an eight-year follow-up. Most of the described studies did not show lesion recurrence after using the conservative surgical treatment. However, we draw attention to the importance of the long follow up period of our case.
RESUMEN: El objetivo de este estudio fue describir el tratamiento quirúrgico conservador del queratoquiste odontogénico, obedeciendo las pautas de CARE (Case Report Guidelines). Los hallazgos clínicos y demográficos en la literatura se compararon basándose en una revisión desarrollada a través de los Criterios de calidad establecidos en la literatura para casos clínicos y series de casos, donde se consultaron cuatro bases de datos para la investigación en salud. La lesión encontrada en el paciente del presente estudio fue detectada en un examen radiográfico de rutina, sin manifestaciones clínicas siendo tratada quirúrgicamente con abordaje conservador. El tratamiento con enucleación, curetaje e instalación de drenaje se instituyó al mismo tiempo quirúrgico y, actualmente, no muestra signos de recurrencia de la enfermedad. De los 27 casos utilizados en la revisión, la lesión predominó en pacientes hombres adultos,con un seguimiento medio de 46,7 ± 28,1 después de la cirugía. Los principales hallazgos clínicos como asociación con dientes, localización, patrón radiográfico y lesión extensa, corroboran el patrón clásico de presentación de la enfermedad descrito en el caso reportado. En conclusión, el tratamiento conservador fue exitoso para el caso clínico descrito, durante un seguimiento de ocho años. La mayoría de los estudios revisados no mostraron recurrencias con el tratamiento quirúrgico conservador empleado, sin embargo, se aconseja realizar un seguimiento a largo plazo.
ABSTRACT
A prótese bucomaxilofacial permite a reabilitação de pacientes que sofreram algum tipo de mutilação facial. A reabilitação protética e utilização de obturadores maxilares após maxilectomia com comunicação das cavidades bucal e nasal possibilitam uma adequada condição de deglutição e fala, garantindo uma melhor qualidade de vida e reintegração social de portadores de sequelas cirúrgicas. O carcinoma mucoepidermoide (CME) é a neoplasia maligna de glândula salivar mais frequentemente encontrada na cavidade bucal, principalmente no palato e região parotídea. Já o carcinoma escamocelular (CEC) é uma das neoplasias malignas mais comuns na cavidade bucal, predominando na região de língua e assoalho, sendo rara na região de seio maxilar. Ambos os carcinomas apresentam-se frequentemente como um aumento de volume assintomático de evolução reativamente lenta, sendo a excisão cirúrgica com margem de segurança o tratamento de escolha. O objetivo deste artigo é relatar dois casos clínicos de reabilitação com prótese obturadora maxilar, após cirurgia oncológica para tratamento de CME e CEC em palato e seio maxilar respectivamente, seguido de comunicação buconasosinusal. A prótese possibilitou não apenas a devolução da estética mas também da função, permitindo a reintegração social do paciente.
A maxillofacial prosthesis allows the rehabilitation of patients who have suffered some type of facial mutilation. Prosthetic rehabilitation and the use of maxillary obturators after maxillectomy, with communication of the oral and nasal cavities, provide a suitable condition for swallowing and speech, ensuring a better quality of life and social reintegration of patients with surgical sequelae. Mucoepidermoid carcinoma (MEC) is a malignant neoplasm of the salivary gland most often found in the oral cavity, especially on the palate and in the parotid region. For its part squamous cell carcinoma (SCC) is one of the most common malignancies in the oral cavity, predominantly in the region of the tongue and floor. It often presents as an asymptomatic bulging with a relatively slow progression, for which surgical excision, with a margin of safety, is the treatment of choice. The purpose of this paper is to report two cases of rehabilitation with a maxillary obturator prosthesis after oncologic surgery for treatment of MEC and SCC on the palate and a maxillary sinus, respectively, followed by buconasosinusal communication. The prosthesis allowed not only the recovery of an aesthetically pleasing appearance but also of function, making possible the patient's social reintegration.
