Abstract:
Sequela of complex craniomaxillofacial trauma is common. We report a previously undocumented, highly unusual, postfacial trauma presentation of a "nasomalar ball-valve fistula." The clinical presentation was a sharp influx of air into the left malar subcutaneous space with each nasal inspiration, followed by near-complete deflation upon each expiration. We also report a very simple and elegant solution of using a nasal trumpet to completely resolve this problem without the need for additional operation. The final recovery was uneventful. We hope to make all facial surgeons aware of this diagnosis and to remind them to keep this simple device in their armamentarium to address similar issues.
