Description
Summary:The results of the bacteriologic samples taken from 7 orbit-exenterated patients who use orbitofacial prosthesis are presented. The objective was to describe which microorganisms colonized the prosthesis and the cavity at the beginning, at 3 months, and at 6 months. The microbiologic studies reported the presence of Staphylococcus epidermis and Staphylococcus aureus in the exenterated cavities in 57% of the patients and in the orbitofacial prosthesis in 14.5% during the first month; in the third month orbitofacial prosthesis Staphylococcus pyrogenes in 4 patients and exenterated cavities S. epidermis in 85.7%; in the 6th month S. pyrogenes in 28.5% (2 patients) in orbitofacial prosthesis and S. epidermis in 100% in the exenterated cavities. The patients who already defeated the infection were able to receive the treatment according to the antibiotic sensitivity of the microorganism and the change of the prosthesis. Once the results of the treatment are given, we suggest providing precise instructions to the patients in order to prevent infection. Se presentan los resultados de tomas bacteriológica llevadas a cabo en 7 pacientes exenterados de órbita portadores de prótesis orbitofacial. El objetivo fue describir qué microorganismos colonizan la prótesis y la cavidad al inicio, a los 3 y a los 6 meses. Los informes microbiológicos reportaron al primer mes en las cavidades exenteradas Staphylococcus epidermis y Staphylococcus aureus en el 57.2%, en las prótesis orbitofaciales se encontraron Staphylococcus aureus en un 14.5%; al tercer mes, en las prótesis orbitofaciales Staphylococcus pyogenes en 4 pacientes y en cavidades exenteradas Staphylococcus epidermis en el 85.7%; al sexto mes Staphylococcus pyogenes en un 28.5% (2 pacientes) para prótesis orbitofaciales y Staphylococcus epidermis en el 100% de las cavidades exenteradas. Los pacientes con la infección ya manifiesta fueron susceptibles de tratamiento de acuerdo a la sensibilidad antibiótica del microorganismo y al cambio de la prótesis, y dados los resultados sugerimos suministrar indicaciones precisas a los pacientes para prevenir infecciones.
