Peritonsillar abscess (PTA), also known as a ''quinsy'' or ''quinsey'', is a recognized complication of tonsillitis and consists of a collection of pus beside the tonsil in what is referred to as peritonsillar space (''peri''—meaning surrounding). It is a commonly encountered otorhinolaryngological (ENT) emergency. ==Symptoms and signs== Unlike tonsillitis, which is more common in the pediatric age group, PTA has a more even age spread, from children to adults. Symptoms start appearing two to eight days before the formation of an abscess. Progressively worsening, unilateral sore throat and pain during swallowing usually are the earliest symptoms. As the abscess develops, persistent pain in the peritonsillar area, fever, malaise, headache and a distortion of vowels informally known as "hot potato voice" may appear. Neck pain associated with tender, swollen lymph nodes, referred ear pain and halitosis are also common. While these signs may be present in tonsillitis itself, a PTA should be specifically considered if there is limited ability to open the mouth (trismus). In short: * Severe unilateral pain in the throat; * Pyrexia (fever) above ; * Unilateral earache; * Odynophagia (pain during swallowing) and difficulty swallowing saliva; * Change in voice (muffled voice, thickened speech, "hot potato" voice); * Intense salivation and dribbling, foetor oris (halitosis); * Pain in the neck; * Malaise, headache, stiffness; * Trismus (an inability to open the mouth completely). Trismus is common. Physical signs include redness and edema in the tonsillar area of the affected side and swelling of the jugulodigastric lymph nodes. The uvula may be displaced towards the unaffected side. Odynophagia (pain during swallowing), and ipsilateral earache also can occur. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Peritonsillar abscess」の詳細全文を読む スポンサード リンク
