Introduction:
This report describes the removal of a missed impacted large piece of a glass that reaches the infra-temporal region after a traumatic injury at the submandibular area.
Case presentation:
A nine year-old patient presented with a limited mouth opening (0.5 cm). Initial examination showed a scar of an old trauma in the submandibular area two months prior to presentation. The radiographic study showed a large knife-shaped foreign body with its tip at the infra-temporal region, and its base at the submandibular region. Further multi-slice computed tomography with angiography was done that showed close proximity of the foreign body to the branches of the external carotid artery; maxillary, lingual and facial branches. The foreign body was removed via extra-oral approach through the old scar of the past injury under general anesthesia. Dissection, exposure of the external carotid artery and preparing it for emergency ligation, were done before extraction of the foreign body. The patient's mouth opening increased to 2.5 cm without any complications.
Conclusion:
Cut wounds in the face should not be repaired in the primary care without detailed history, systematic examination and proper investigations.
