RESUMO
Background: Zygomatic implants have been used to treat severe atrophy maxilla. Since its description, the technique has been improved in order to reduce patient morbidity as well as prosthesis rehabilitation time. Despite the improvements in the procedure, zygomatic implant treatments still have complications related to the peri-implant soft-tissue; a probing depth greater than 6 millimeter (mm) and a prevalence of bleeding on probing of 45% have been described. The mobilization of the buccal fat has been used to manage different oral and maxillofacial soft-tissue pathologies. The aim of this study was to assess whether the buccal fat pad might prevent mucosal dehiscence and avoid potential postoperative complications when is placed covering the body part of the zygomatic implants. Material and methods: In this pilot study, 7 patients were enrolled and a total of 28 zygomatic implants were placed and evaluated during a 12-month follow-up period. Surgical sites were randomly divided into two groups before implant placement: control group (A; in which no buccal fat pad was applied) and experimental group (B). Peri-implant soft tissue thickness difference, pain using a Visual Analog Scale (VAS), swelling, hematoma, buccal soft tissue healing and sinusitis, were evaluated. The implant survival rate was determined according the Aparicio success criteria and compared between the control and experimental procedure. Results: A nonstatistical difference was found between groups regarding to pain. The experimental group showed higher soft-tissues thickness (p= 0.03) and the implant survival rate was 100% in both groups. Conclusions: The mobilization of the buccal fat pad to cover the body of the zygomatic implants increases peri-implant soft-tissue thickness, without increasing the postoperative pain. (AU)

RESUMEN Introducción: La disfagia tiene una morbimortalidad importante en pacientes hospitalizados. Objetivos: principal; describir las características de los pacientes con disfagia hospitalizados y, secundarios; cuantificar y analizar la prevalencia de mortalidad y de reingresos. Metodología: Estudio transversal descriptivo de las hospitalizaciones por disfagia durante el año 2015 en un Hospital General Universitario. Resultados: Se evaluaron 431 historias clínicas. La edad de los pacientes fue de 83,21 (DE 11,4) años, el 52,5% fueron mujeres y el 47,2% varones; la estancia media fue de 11,1 (DE 7,99) días. En el 71,2 % de los casos la disfagia fue por afectación de la fase orofaríngea. En el 80,51% de los casos se diagnosticaron complicaciones respiratorias: 48,12% neumonía aspirativa por líquidos, 40,05 % neumonitis química por aspiración y 11,81% neumonía aspirativa por sólidos. La mortalidad general asociada a las complicaciones respiratorias respecto del total de los casos de disfagia fue del 24,49%. El 50,48% de los pacientes con neumonía aspirativa fallecieron. La principal causa de la disfagia fue las enfermedades neurológicas (un 77,25%). La mortalidad fue significativamente mayor en las mujeres - 42,3% frente al 7,8% - (p < 0,01) y esta diferencia se mantuvo tras ajustar el resultado por edad: OR 9,937, IC95%: 5,446; 18,131. El 13,10% de los pacientes reingresaron al menos en una ocasión. Los pacientes de geriatría presentaron un mayor número de reingresos por número de ingresos. Discusión: las enfermedades neurológicas fueron la principal causa de disfagia. La mortalidad fue significativamente mayor en las mujeres.
ABSTRACT Introduction: Dysphagia is an important associated morbidity and mortality in hospitalized patient. Objectives: Main; to describe the characteristics of patients admitted for dysphagia and secondary; quantify and analyze the prevalence of mortality and readmissions. Methodology: Cross-sectional study descriptive revenues by dysphagia during the year 2015 in a University General Hospital. Results: 431 records were evaluated. The age of the patients was 83,21 (11.4), 52.5% women and 47.2% male; the average stay was 11.1 (7.99) days. In 71,2% of cases the dysphagia was involvement of the oropharyngeal phase. 80.51% of cases were diagnosed respiratory complications. The percentage distribution of these complications were: in 48.12% aspiration pneumonia due to fluids, in 40.05% chemical aspiration pneumonitis and in 11.81% aspiration pneumonia due to solids. The overall mortality associated with respiratory complications compared to the total of cases of dysphagia was 24.49%. 50.48% of patients diagnosed with aspiration pneumonia died. The main cause of dysphagia was neurological diseases (77.25%). Mortality was significantly higher in women - 42.3% of women compared with 7.8% of males - (p < 0.01) and this difference remained after adjusting the result by age: OR 9,937, 95% CI: 5,446; 18,131. 13.10% of patients re-entered at least on one occasion. Patients of geriatric unit that presented in greater number of readmissions by admissions. Discussion: neurological diseases were the main cause of dysphagia. Mortality was significantly higher in women
