During the past decades, studies from the United States, Finland, Sweden, the Netherlands, the United Kingdom, and Scotland showed an increase in the incidence of OSCC, tonsillar cancer, and base of tongue
In the United States, between 1973 and 2001, the incidence of oral (mobile) tongue, base of tongue
, and palatine tonsil squamous cell carcinoma increased significantly in patients between 20 and 44 years of age (annual percentage changes of +2.
Requirements to be considered for the study include previously diagnosed obstructive sleep apnea with an apnea-hypopnea index (AHI) of between 15 and 50, and inability to continue using CPAP (continuous positive airway pressure), and airway obstruction primarily at the base of tongue
UPPP is an invasive procedure that typically requires general anesthesia and an overnight hospital stay and it does not address obstructions at the base of tongue
Ablation of advanced tongue or base of tongue
cancer and reconstruction with free flap: Functional outcomes.
While the majority of all head and neck cancers are linked to tobacco and alcohol use, over half of tonsil and base of tongue
cancers are linked to HPV.
Liposarcoma of the base of tongue
and tonsillar fossa: A possibly underdiagnosed neoplasm.
Shrinkage of submucosal tissue can be applied to structures such as tonsils and base of tongue
to provide relief of upper airway obstructions.
The mild stimulation is intended to restore tone during sleep to the muscles that control the base of tongue
, preventing the tongue from collapsing and obstructing the airway during sleep.
Surgical treatment of squamous cell carcinoma of the base of tongue
The Somnoplasty System treats sleep apnea by shrinking soft tissue in the upper airway including the base of tongue
, the source of obstruction that is most difficult to treat.
Primary site was base of tongue
in 15 patients, tonsil in 6 patients, and glossopharyngeal sulcus in one patient.
