Background:
B-scan ultrasonography is widely used in diagnostics of head and neck pathologies. Ultrasonography can be applied intraoperatively to identify foreign materials.
Case report:
This case report describes the ultrasonographic identification of foreign bodies of the eye lid and parapharyngeal space in an adolescent who was injured several years ago, obviously a victim of domestic violence. B-scan ultrasonography (small part transducer, emission frequency: 7.5 MHz) proved to be a reliable tool to locate the foreign bodies. Ultrasound imaging facilitated the decision-making of the surgical approach and thus reduced the surgical exploration time.
Discussion:
B-scan ultrasonography is a valuable tool in oral and maxillofacial surgery. The use of B-scan ultrasonography in the head neck region requires the capacity of the surgeon to fuse the ultrasonographic picture with the topography of the head and neck. The advantages and limitations of B-scan ultrasonography in the head and neck region concerning foreign body identification are briefly discussed.
