Brief Summary:

The investigators wish to evaluate coblation channeling in the treatment of chronic tonsillitis.

Condition or disease	Intervention/treatment	Phase
Tonsillitis	Procedure: Coblation channeling	Phase 2

Detailed Description:

The tonsillar crypts play an important role in chronic tonsillitis. They are covered by stratified epithelium and may be initiated via the epithelium to mount immune responses to various presenting antigens. Go M. et al, investigated the expression and function of tight junctions in the epithelium of human palatine tonsils from patients with tonsillar hypertrophy or recurrent tonsillitis. These studies suggested unique expression of tight junctions in human palatine tonsillar epithelium, and it was suggested that the crypt epithelium may possess an epithelial barrier different from that of the surface epithelium.

Bacteria within biofilms are resistant to host defenses and antibiotics. The presence of bacterial biofilms within the tissue and crypts of inflamed tonsils may explain the chronicity and recurrent characteristics of some forms of tonsillitis. There is strong anatomical evidence for the presence of bacterial biofilms in chronically diseased tonsils.

Our hypothesis was that treatment of the crypts and tonsillar tissue may decrease the possible antigen-immune system interaction and inflammation.

The combination of the radio frequency energy and the fluid creates a "plasma" field containing highly ionized particles. The ionized particles have sufficient energy to break organic molecular bonds that can remove tissue selectively without excessive heat production and damage the surrounding tissue. Employing this new technique, the investigators will try to eliminate the cause for chronic tonsillitis.

Intervention/treatment

Experimental: Coblation

Procedure: Coblation channeling; The combination of the energy and the fluid creates a "plasma" field containing highly ionized particles (coblation). The ionized particles have sufficient energy to break organic molecular bonds that can remove tissue selectively without excessive heat production and subsequent damage to the surrounding tissue. Treatment of the tonsillar crypts and tissue by coblation may decrease antigen and immune system interaction and inflammation.

Primary Outcome Measures :

1. RF coblation may be promising in treating chronic tonsillitis. [ Time Frame: 2 years ]

Secondary Outcome Measures :

1. RF coblation reduces tonsillar volume and pain in comparison to surgery; may be performed as an out-patient procedure. [ Time Frame: 2 years ]
