Lower lip abscess by foreign body embedded after facial trauma and application of ultrasound in diagnosis: A case report

Oral and maxillofacial trauma frequently results in both hard and soft tissue injuries. This case report presents a 3-year-old patient who developed a lower-lip abscess due to foreign bodies two months post-trauma. Clinical examination revealed swollen masses in the skin and mucosa of the lower lip. After diagnosing the abscess, the foreign body was removed, leading to full recovery. This case emphasizes the importance of thorough clinical examination, detailed medical history, appropriate paraclinical testing, and the use of ultrasound as a superior diagnostic tool, given its safety, non-invasiveness, and diagnostic efficacy, especially when X-rays are inconclusive.
