颈内动脉腐败性坏死曾经是扁桃体周围脓肿的主要并发症,在广泛应用抗生素后,已日趋稀少。作者们报道此并发症一例,并复习文献,描述了本病的临床特点。由于扁桃体的感染侵入咽上缩肌和扁桃体被膜之间隙或扁桃体前后柱颊咽筋膜之间隙发生扁桃体周围脓肿。更可因扁桃体血管血栓性静脉炎或颈深淋巴结感染通过淋巴管进一步扩展到咽旁间隙。咽旁间隙由茎突和茎突下颌韧带分为前后两部分,前部主要为肌肉,后部则主要含神经血 Corrosive necrosis of the internal carotid artery has been a major complication of peritonsillar abscess and has become increasingly scarce after the widespread use of antibiotics. The authors report an example of this complication and review the literature describing the clinical features of the disease. Tonsillar abscesses occur around the space between the pharyngeal constrictor muscle and the amygdala membrane due to the infection of the tonsil or between the cheek and pharyngeal fascia around the amygdala. More due to tonsillar vascular thrombophlebitis or cervical deep lymph node infection through the lymphatic vessels further extended to the parapharyngeal space. Parapharyngeal space by the styloid process and styloid process of the mandibular ligament into two parts before and after, the main part of the muscle, the latter mainly contains neurogenic blood
