Adenoidectomy is among the most common surgical procedures performed in children.  The two major indications are nasopharyngeal airway obstruction and recurrent or chronic infections of the nasopharynx.  This surgery is often carried out with a combined tonsillectomy which is performed for similar indications and depicted here.



Adenoidectomy with Radiofrequency Ablation (Coblator) Technique: A Crowe-Davis mouth gag is placed to provide adequate visualization of the oral cavity. A red rubber catheter is passed from the nose through the nasopharynx and back out through the mouth to provide anterior retraction of the soft palate. A dental mirror is placed in the oropharynx to enable adequate visualization of the nasopharynx. Radiofrequency ablation (Coblation) is used to remove the adenoid tissue. Hemostasis is achieved and the nasopharynx should be irrigated. Prior to cessation of anesthesia, an orogastric tube should be used to suction fluid from the stomach.
