Coblation Tonsillotomy Versus Radiofrequency and Cold Knife Dissection Tonsillectomy

Tonsils were dissected from the surface inward with the wand set at Coblate 7 setting. The wand skims the tonsil surface with continuous saline irrigation. Ablation was performed without penetrating the tonsillar capsule. Retraction of the tonsillar pillars is done to define the margins for near complete ablation. When the capsule is approached, the wand is turned down to Coblate 3 setting. Thin layer of tonsillar tissue is left to protect the capsule. Bleeding does not occur in most cases, but when it occurs, the wand was used in the Coagulate 5 setting for homeostasis

Begin by retracting the anterior tonsillar pillar to expose the tonsil, use a cold knife (scalpel or tonsil dissector) to make an incision along the anterior pillar near the mucosal margin of the tonsil, identify the plane between the tonsillar capsule and the underlying pharyngeal muscle, then carefully dissect the tonsil away from the surrounding tissues, following the plane to avoid trauma to the underlying structures, proceed from the superior pole of the tonsil to the inferior pole, ensuring that the entire tonsil is removed, use gauze or sponges to control minor bleeding during the procedure, for more significant bleeding, apply direct pressure or use ligatures and cold packs, achieve final hemostasis using absorbable sutures or electrocautery if needed
