The examinee assumes an orthophoric sitting position, with the mouth opening for peaceful respiration. After the examinee puts his tongue in the floor of mouth flatly, the examiner holds a spatula with the hand to press the former’s tongue downwards. It is advisable to place the distal spatula on the juncture of 2/3 part of anterior tongue and 1/3 part of posterior tongue, for if it is placed too deep, nausea and vomiting will easily occur while if it is placed too shallowly, pharyngeal portion can not be fully exposed. Do not press the proximal spatula downwards. This can prevent the tongue from being held down by teeth to cause pain. As for the patient with reflex sensitization, spray 1% dicaine solution onto the part to be examined once or twice before the examination.
Take care to observe the shape of the oropharyngeal portion, colour and luster of the mucosa, the size of tonsil, whether there exist congestion, secretion, pseudomembrane, ulcer and neoformation or not as well as the activities of soft palate, pharynx wall, anterior and posterior palatal arch. If pulling the anterior palatal arch forwards with a retractor, the examiner can see better the real conditions of the tonsil.
Nasopharyngeal examination, namely, posterior rhinoscopy, please refer to “Posterior rhinoscopy” of discussion of the nose.
