How to examine

Throat examination consists of 3 steps: oral examination, throat examination without tools, throat examination with the instrument.

Oral examination: the mouth and throat are closely related. It is impossible to examine the throat without examining the mouth. Use the tongue to lift the cheeks to see the teeth, gums and the inside of the cheek to see the palate and drapes of value in diagnosis telling the patient to curl their tongue up to see the floor of the mouth and the underside of the tongue.

Examination of the throat without tools: ask the patient to open their mouth, stick out their tongue and moan ..., the tongue will pull up and the tonsils will appear in a normal position. This way of examining the patient is not nauseous.

Throat examination with instruments:

Examination of the throat with tongue pressure:

Want a good examination should local anaesthesia to avoid the vomiting reflex. Have the client open their mouth and not stick out their tongue to breathe gently.

The physician places lightly on the tongue on 2/3 in front of the tongue, then presses the tongue slowly down, should not be left for too long. We need to see: the pharynx, reed, the anterior column, the posterior pillar, the tonsils and the posterior wall of the throat, to see clearly the tonsils can be used to lift the pillar, to the front to the side, pay attention to the movement of the pharynx, chicken tongue.

Normal picture: balanced pharynx, uneven reed, moderate-sized tonsils without pus spots, erythematous mucosa. The anterior and posterior posts are normally not congested red, the posterior wall is clean.

  Common pathological picture: the reed is skewed, the tonsils have many pus spots, the lymphoid organization is overgrown in the back of the throat.

Throat examination with brooch: use cotton swab to gently poke the pharynx, the base of the tongue, the back of the throat to see if the patient has vomiting reflex? if no reflexes, it means loss of sensation of line V of line IX and X.

Examination of the nasopharynx by mirror: in the posterior nose examination, holding the left hand holding the tongue and holding the small mirror handle threaded out behind the curtain. Meanwhile, the patient breathes through the nose. We can observe the back door, dome roof, Esutachi nozzle. See if there are no tumours? Is there an ulcer in the nasopharynx? Is there a back door polyp?
