This case highlights the value of interdisciplinary awareness and advanced imaging.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Introduction<\/jats:title>\n                    <jats:p>A 9-year-old boy with unilateral nasal obstruction (previously misdiagnosed as rhinitis) was referred to dentistry due to dental trauma. Initial panoramic X-ray identified an inverted ST but lacked clarity. Subsequent cone-beam computed tomography (CBCT) with multiplanar reconstruction and 3D segmentation confirmed an inverted ST in the anterior maxilla with palatal perforation and nasal invasion. The tooth was extracted via a minimally invasive palatal approach guided by a 3D model, resulting in immediate resolution of nasal symptoms and a good postoperative recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Odontogenic causes must be included in the differential diagnosis for children with refractory unilateral nasal symptoms, highlighting the critical need for interdisciplinary collaboration between dentists and otorhinolaryngologists. While panoramic X-ray is a useful preliminary screening tool, CBCT is essential\u2014not only for accurate preoperative diagnosis and safe, minimally invasive surgical planning but also for postoperative confirmation of complete removal.<\/jats:p>\n
