A method is disclosed for treating benign conditions, such as enlarged tonsils and / or adenoids located in a patient's throat or nasopharynx, or soft tissue lesions located in a patient's oropharynx or larynx. According to the method, a space containing the patient's nasopharynx, oropharynx or pharynx and larynx is isolated from the patient's trachea and lungs using an inflatable cuff tracheostomy tube or nasotracheal tube inserted in the patient's trachea. The cuff is inflated to occlude the trachea. The patient is placed in a supine position, whereupon at least a portion of the space containing the nasopharynx and / or oropharynx and larynx is filled with saline. An endoscope is then inserted into the space to view the operative site in which the tonsils or tissue lesion are to be treated. An electrosurgical instrument having an active tissue treatment electrode and a return electrode connected to an electrosurgical generator is then inserted into the space, either along side the endoscope or through the endoscope's working channel. The generator is then operated to apply a radio frequency voltage between the active and return electrodes of the electrosurgical instrument, whereby a conduction path is formed between the active and return electrodes, at least partially through the saline, whereupon the active electrode is manipulated to debulk or otherwise treat the soft tissue lesion or enlarged tonsils and / or adenoids.

A swallow challenge medium is thixotropic for easy swallowing and to provide enough viscosity for effective challenge to peristalsis and has high ionic density for effective impedance measurements by contact with electrodes positioned in a person's esophagus or oropharynx during swallow testing. The medium also has a high surface tension so as not to adhere to or coat the electrodes or probe surfaces. These physical characteristics are stabilized and consistent enough to provide standard for esophageal and / or oropharyngeal function testing and diagnostics.

A removable intraoral apparatus for improving airway patency is described. Wearing the apparatus alters the position, configuration and freedom of movement of the tongue, the muscles of mastication, as well as the pharyngeal and facial muscles. The apparatus is useful for correcting snoring and / or obstructive sleep apnea due to intermittent closures or partial obstructions occurring in the oropharynx during sleep. The apparatus of the invention can improve various types of airway disorders and improve oral functions by changing the position, configuration and freedom of movement of selected portions of the tongue and mouth, reducing the resistance to air flow in the mouth and pharynx, re-orienting and reprogramming the muscles of the mouth and tongue, and maintaining a proper oral systemic balance.
