Infraorbital space infections are rare but potentially severe complications arising from foreign body impalement in the maxillofacial region. This case report details a 52-year-old male presenting with left facial pain and swelling following a fall onto dry plant twig. The initial examination revealed diffuse swelling, erythema, and active pus drainage in the left infraorbital region. Despite preliminary care, the patient's symptoms persisted, leading to further investigation. A Cone Beam Computed Tomography (CBCT) scan revealed subcutaneous edema and hematoma, but did not initially identify the foreign body. Upon debridement, a 6 cm wooden particle was discovered and removed under local anesthesia. The patient was treated with intravenous antibiotics, analgesics, and corticosteroids, and showed significant improvement post-operatively. The culture and sensitivity testing of the pus drained revealed no bacterial growth, and the patient was discharged with a course of oral antibiotics. Follow-up demonstrated complete resolution of the infection, with satisfactory wound healing. This case underscores the diagnostic challenges posed by organic foreign bodies, which may not be readily visible on imaging studies. The importance of thorough clinical examination, patient history, and appropriate imaging techniques is emphasized to prevent misdiagnosis and complications. The management of such injuries requires a multidisciplinary approach, including meticulous surgical debridement and adequate antibiotic coverage to ensure optimal outcomes. This case also highlights the necessity for heightened awareness and caution in cases of facial trauma, even when initial imaging does not suggest the presence of a foreign body.
