Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - The buccal space lies between the buccinator muscle and the overlying superficial fascia and skin. The maxillary 2nd and 3rd molars are the usual nidus of buccal space infections, eroding either superiorly through the maxillary alveolar bone or, rarely, inferiorly from the 3rd mandibular molar through the mandibular alveolar bone into the buccal space. Patients usually present with unilateral facial swelling, redness, and tenderness of the cheek. Trismus is generally not present. Parotid gland enlargement due to mumps and suppurative bacterial parotitis should also be considered. The former lacks erythema and warmth of the overlying skin, while the latter is accompanied by trismus and purulent drainage from Stensen’s duct. Inspection of all the maxillary and 3rd mandibular molar teeth is essential to make the diagnosis. A CT scan may help localize the infection.
