[en] INTRODUCTION AND OBJECTIVES. The coronavirus pandemic (COVID-19) since it was identified in December 2019 has brought with it multiple restrictive measures for the world population. In Spain we have lived through different stages of confinement and social distancing rules. These measures have had an impact not only on the daily activity of the population, but also on the functioning of Spanish Hospitals. As for the field of Oral and Maxillofacial Surgery, facial trauma is the most frequent surgical emergency. Since the incidence of trauma is directly related to the lifestyle and customs of the population, it is logical to speculate that the measures taken to curb the pandemic have caused a change in the incidence and patterns of maxillofacial fractures. The main objective of the study is to evaluate the impact of the coronavirus pandemic on the incidence and characteristics of maxillofacial fractures. MATERIAL AND METHODS. A research protocol of a retrospective cohort observational study has been designed. We will include patients operated for facial fractures by the Oral and Maxillofacial Surgery Departments of the Virgen del Rocío and Virgen Macarena Hospitals in Seville. Three groups of patients will be compared according to the year of surgical intervention. Group 1, patients operated on in the year prior to the pandemic; group 2, patients operated on in the first year of the pandemic; and group 3, patients operated on in the second year of the pandemic. Changes in the incidence, epidemiology, etiology, patterns and treatments of facial fractures will be studied using descriptive and inferential statistical analysis techniques.

[gl] INTRODUCIÓN E OBXECTIVOS. A pandemia debida ao novo coronavirus (COVID-19) desde que se identificou en decembro de 2019 trouxo consigo múltiples medidas restritivas para a poboación mundial. En España vivimos diferentes etapas de confinamento e normas de distanciamento social. Estas medidas repercutiron non só na actividade diaria da poboación, senón tamén no funcionamento dos hospitais de todo o territorio español. No campo da Cirurxía Oral e Maxilofacial, os traumatismos faciais son a urxencia cirúrxica máis frecuente. Dado que a incidencia dos traumatismos garda relación directa a forma de vida e as costumes da poboación é lóxico especular as medidas adoptadas para frear a pandemia ocasionaron un cambio na incidencia e os patróns das fracturas maxilofaciais. O obxectivo principal do estudo é avaliar o impacto que tivo a pandemia de coronavirus na incidencia e características das fracturas maxilofaciais. MATERIAIS E MÉTODOS. Deseñouse un protocolo de investigación para un estudo de cohortes observacional retrospectivo. Incluiranse no estudo os pacientes intervidos por fracturas faciais polos servizos de Cirurxía Oral e Maxilofacial dos hospitais Virxe do Rocío e Virxe Macarena de Sevilla. O grupo 1, formado polos pacientes intervidos o ano previo á pandemia; grupo 2, os pacientes intervidos o primeiro ano de pandemia; e, grupo 3, os pacientes operados o segundo ano de pandemia Estudaranse os cambios de incidencia, epidemioloxía, etioloxía, patróns e tratamentos das fracturas faciais empregando técnicas de análise estatística descritiva e inferencial.
