Correct answer: E — Buccal space

The buccal space is bounded laterally by skin and subcutaneous tissue, medially by the buccinator muscle, anteriorly by the muscles of facial expression, posteriorly by the masseter and ramus, superiorly by the zygomatic arch, and inferiorly by the mandibular body. Buccal space infections typically arise from mandibular or maxillary molar infections whose roots penetrate buccal to the buccinator attachment. They present as dramatic facial swelling but are generally less dangerous than deep space infections.
