Submasseteric space infections are rare at any age but particularly so in primary school children. The origin of the infection is usually odontogenic, from pericoronitis in a third molar. Submasseteric inflammation is a deep facial space inflammation, often progressing to mature abscess, and usually misdiagnosed as staphylococcal or streptococcal lymphadenitis or pyogenic parotitis. The hallmark of a masticatory space infection is trismus. The cardinal signs of this infection include a firm mass in the body of the masseter muscle with overlying cellulitis with trismus.
咬肌下间隙感染在任何年龄段都很罕见，在小学生中尤为如此。感染通常起源于牙源性，由第三磨牙的冠周炎引起。咬肌下炎症是一种深部面部间隙炎症，常发展为成熟脓肿，通常被误诊为葡萄球菌或链球菌性淋巴结炎或化脓性腮腺炎。咀嚼肌间隙感染的标志是牙关紧闭。这种感染的主要体征包括咬肌肌腹有硬结，伴有覆盖其上的蜂窝织炎及牙关紧闭。
