Tonsillectomy with Radiofrequency Ablation (Coblator) Technique

Tonsillectomy is among the most common surgical procedures performed in children.  The two major indications are oropharyngeal airway obstruction and recurrent or chronic infections of the oropharynx.  In this video, radiofrequency ablation, or Coblation (controlled ablation), is the technique used to ablate the tonsils.  This technique uses low-temperature radiofrequency and saline to create a plasma field that dissolves tissue.  It is generally safer that high-temperature electrocautery and allows for precise removal of tissue without burning nearby structures.

Obstruction or chronic/recurrent infections of the oropharynx
Active local infection, certain hematologic disorders, certain pharyngeal anatomical abnormalities
The patient is placed under general anesthesia. A mouth retractor is placed to allow for visualization of the oral cavity.
Complete history and focused physical with anesthesia evaluation
The tonsils are situated in the lateral walls of the posterior oral cavity between the tonsillar pillars.
