Biopsia de lesión orofaríngea - Overview

Nombres alternativos

Biopsia de lesión en la garganta; Biopsia de la boca o la garganta; Biopsia de lesión en la boca

Definición:

Es una cirugía en la cual se extrae tejido de un tumor o úlcera bucal anormal y se analiza para ver si hay problemas.

Forma en que se realiza el examen:

Primero se aplica un analgésico o un medicamento insensibilizador en el área. Para las lesiones grandes o las lesiones de garganta se puede necesitar anestesia general.

Se extrae toda la lesión o una parte de ella y se envía al laboratorio para verificar si hay problemas. Si hay una masa en la boca o en la garganta, la biopsia puede ser la primera parte de la extirpación del tumor.

Preparación para el examen:

Si se va a utilizar anestesia local o un analgésico simple, no se necesita preparación alguna. Si el examen es parte de una extirpación de un tumor o si se va a utilizar anestesia general, le pueden solicitar no comer nada durante 6 a 8 horas antes del procedimiento.

Lo que se siente durante el examen:

Se puede sentir presión o sensación de tirón mientras se extrae el tejido. Después de que desaparece el entumecimiento, el área puede estar sensible durante unos cuantos días.

Razones por las que se realiza el examen:

El examen se realiza para determinar la causa de una úlcera (lesión) en la garganta.
