AbstractSubmasseteric 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.
