We report the second case of a bullet from a non-powder weapon in the pterygopalatine fossa described in the English literature and the first removed by open trans-sinusal surgery. A 53-year-old male patient was shot and referred from another hospital for removal of a bullet from the pterygopalatine fossa. The patient had a craniofacial CT scan and was in good general condition. The foreign body was trans-sinusally non-endoscopically removed. The experience, knowledge and manual dexterity of the operator allowed avoiding iatrogenic complications such as intraoperative bleeding and nerve injury. The basis for a successful operation was good diagnostic, including radiological diagnostic consisting of performing a cranio-facial CT scan.</p> <p>&nbsp;</p> Filip Blizniak Karolina Lubecka Maciej Chęciński Sławomir Karawan Wojciech Gola Maciej Sikora Copyright (c) 2025 Filip Blizniak, Karolina Lubecka, Maciej Chęciński , Sławomir Karawan, Wojciech Gola, Maciej Sikora http://creativecommons.org/licenses/by-sa/4.0 2025-02-06 2025-02-06 40 1 1 14 10.14428/nemesis.v40i1.86853
