“…After consulting anatomic textbooks, we added the diagnosis of an anterior nasal spine fracture. Most et al 4 concluded that anterior nasal spine fractures are rarely reported, but we found that fractures involving this structure might not be as rare as described in the literature. Indeed, it was a lack of awareness of the anterior nasal spine that resulted in missed diagnosis of fractures.…”

“…Based on the extant literature, fractures of the anterior nasal spine are rare, 1 and only 4 cases have been reported (1 case diagnosed by CT and 3 cases by plain film radiographs). [1][2][3][4] In the present study, however, 44 anterior nasal spine fractures were identified based on CT examinations in 200 patients with maxillofacial trauma. Although nearly one-fourth of patients had nasal spine fractures (22.00% [44 of 200]), only 2 patients were originally diagnosed by CT.…”

“…The literature pertaining to the anterior nasal spine and its fractures is limited. [1][2][3][4] Fracture of the anterior nasal spine is considered to be rare based on the extant literature. Because the anterior nasal spine is usually ignored by physicians, 1 anterior nasal spine fractures are often missed.…”

Objective: To study anterior nasal spine fractures, including the incidence, missed diagnosis rates, and relationship with shapes using computed tomography (CT). Methods: Two hundred cases of axial CT images performed for maxillofacial trauma were reviewed. The incidence, correct, and missed diagnosis rates of anterior nasal spine fractures were studied. The relationship between the fracture and the shape of the anterior nasal spine was also analyzed. Results: The rate of anterior nasal spine fractures was 22.00% (44 of 200). The diagnostic accuracy was 4.55% (2 of 44) and the missed diagnosis rate was 95.45% (42 of 44). The fracture rates of the double rod, single rod, triangle, and irregular anterior nasal spine were 33.85% (22 of 65), 32.26% (10 of 31), 12.24% (12 of 98), and 0.00% (0 of 6), respectively. The double and single rod types of anterior nasal spine were most likely to be fractured than the type of triangle (χ2 = 11.05, 6.67, P < .0167). No fracture was found in the irregular type of anterior nasal spine. Conclusion: Anterior nasal spine fractures are not rare and the high missed diagnostic rate results from unfamiliarity with the structure. Double and single rod types of anterior nasal spines are easy to fracture. Bony reconstruction and thin thickness of CT images are necessary for diagnosis.

“…It is surrounded by relatively protruding adjacent facial structures, such as the nasal bone, nasal cartridge, malar bones, mandible, maxilla, and maximum teeth [3]. Concerning this unique anatomical structure and location, the ANS is regarded as less exposed to trauma and not easily fractured, unlike the nasal bone, which is most frequently fractured in facial injuries [1,[4][5][6]. On the other hand, the actual incidence of ANS fracture may not be as low as predicted.…”

“…Therefore, the differential diagnosis of ANS fractures should be considered in patients with mid-facial trauma. The common clinical symptoms of ANS fractures are swelling, tenderness, mouth bleeding, mucosal lip laceration, and submucosal ecchymosis [1][2][3][4]6]. These clinical symptoms can be ignored by patients, and clinicians may overlook physical examinations and radiological findings [2,3].…”

Open Reduction of an Isolated Anterior Nasal Spine Fracture: A Case Report and Review of the Literature

et al. 2023

A 14-year-old girl had a mid-facial trauma event caused by hitting an opening door and experienced discomfort and swelling of the columella and upper lip. Physical examination revealed mild tenderness on light palpation without any discomfort with upper lip movement. A computed tomography scan of the maxillofacial bones with three-dimensional reconstruction showed a fracture of the anterior nasal spine with obvious leftward displacement, mild deviation of the caudal aspect of the nasal septum, and no sign of nasal bone fracture. Open reduction and internal fixation were performed with regard to aesthetic and functional concerns, including nasal septum deviation. The postoperative course was uneventful, and healing proceeded normally without complications. Herein, we emphasize the importance of differential diagnosis of isolated anterior nasal spine fractures in patients with mid-facial trauma and clinicians’ strategic decision-making in treatment modalities.
