Nostril or vestibular stenosis is a rare disease that usually occurs after trauma, infection, or burns in acquired cases. Nostril stenosis in pediatric cases is even rarer; however, it must be considered after trauma. Nostril stenosis involves the proliferation of secondary fibrous tissue in damaged subcutaneous tissues, resulting in a circumferential scar that leads to nasal obstruction on the involved side. Because each case of vestibular stenosis is diverse, no standard treatment has been established. Here, we present cases of successfully treated posttraumatic shallow nostril stenosis in pediatric patients and highlight the importance of early surgery.
