pharynx
(redirected from oropharyngeal)

   Also found in: Dictionary/thesaurus, Medical, Encyclopedia, Wikipedia 0.01 sec.

pharynx

Muscular cavity behind the nose and mouth, extending downwards from the base of the skull. Its walls are made of muscle strengthened with a fibrous layer and lined with mucous membrane. The internal nostrils lead backwards into the pharynx, which continues downwards into the oesophagus and (through the epiglottis) into the windpipe. On each side, a Eustachian tube enters the pharynx from the middle ear cavity.

The upper part (nasopharynx) is an airway, but the remainder is a passage for food. Inflammation of the pharynx is named pharyngitis.

The researchers assessed the role of chronic periodontitis on head and neck squamous cell carcinoma, as well as the individual roles on three subsites: oral cavity, oropharyngeal and laryngeal.
The largest and most definitive study to date has found that patients with stage III or IV oropharyngeal cancer (cancers of the upper throat) whose tumors contained the human papillomavirus (HPV) have better outcomes than patients with HPV-negative disease according to new research from the Radiation Therapy Oncology Group (RTOG).
If possible, patients should brush their teeth and/or rinse their mouths well with water before attempting to collect the specimen in order to reduce the possibility of contaminating it with food particles or oropharyngeal secretions.
