“…Theoretically, telecanthus observed in NOE fractures is a possible complication due to the deviation of the frontal process of the maxillary bone. However, telecanthus was not noted in any of the medial maxillary (nasomaxillary buttress) fractures reported by May et al, [ 1 ] Yoshioka et al, [ 2 ] Anderson et al, [ 4 ] and Hillstrom et al, [ 5 ] or in the patients described in this report. May et al [ 1 ] and Hillstrom et al [ 5 ] suggested that the difference in the fracture pattern between NOE and medial maxillary (nasomaxillary buttress) fractures is due to the difference in the direction of the external force.…”

Rationale: Medial maxillary fractures are defined as fractures of the medial aspect of the maxilla, that is, fractures of the nasomaxillary buttress. The diagnosis of medial maxillary (nasomaxillary buttress) fractures is challenging because of its similarities with nasal, and naso-orbito-ethmoidal (NOE) fractures.Patient concern: The patients included a 17-year-old Japanese man and a 37-year-old Japanese woman with facial injuries. Swelling of the affected cheek, nasal hemorrhage, periorbital ecchymosis, and C-shaped deviation of the nasal dorsum with normal nasal tip and root position were observed. Mild hypesthesia was noted in the affected region innervated by the left infraorbital nerve. Telecanthus, double vision, eye movement disorder, epiphora, trismus, tooth fracture, and malocclusion were absent in both cases.Diagnosis: Based on clinical signs and imaging findings, the patients were diagnosed with medial maxillary (nasomaxillary buttress) fracture.Intervention: The 17-year-old man underwent a reduction of the medial aspect of the maxillary bone with the treatment of concomitant fractures, and the 37-year-old woman did not request treatment.Lessons: Medial maxillary (nasomaxillary buttress) fractures are not included in any current classification of the maxillary fracture patterns. As medial maxillary (nasomaxillary buttress) fractures are similar to nasal, and NOE fractures, careful differential diagnosis is required before selecting the surgical procedure to be performed because the treatment of concomitant fractures is also necessary.

“…Facial fracture sites have been reported to be accessed through a circular incision, which is found in coronal, intraoral, eyebrow, and subcilial incisions, and transconjunctival approaches. 5 , 6 , 9 In the authors’ case, because the orbital rim needed to be fixed, transconjunctival and intraoral approaches were selected. A transconjunctival incision allows surgeons not only to access the fracture site but also to minimize scarring.…”

Summary: The successful reduction of a nasomaxillary fracture was performed using a three-dimensional printed model. A 16-year-old boy was struck in the left orbit by a baseball; subsequently, he was diagnosed with the nasal bone fracture at a hospital, and was referred to the authors’ department. A left nasomaxillary fracture and nasal bone fracture were diagnosed by computed tomography. Standard triangulated language data for the mirror image of the frontal process of the right maxilla were obtained from digital imaging and communications in medicine data for preparing a three-dimensional printed acrylonitrile butadiene styrene model. On postinjury day 13, the frontal process fracture was reduced via transconjunctival and intraoral approaches. After the reduction of the fracture, an absorbable plate fitting to the shape of three-dimensional printed acrylonitrile butadiene styrene model was molded, and the maxillary frontal process and infraorbital rim were reduced and fixed with an absorbable plate and screws. Postoperative computed tomography demonstrated a favorable reduction. The intraoperative use of the 3D printed acrylonitrile butadiene styrene model was helpful in the nasomaxillary fracture reduction and fixation.

“…FFPM alone are poorly described in the literature; they are often mentioned along with an adjacent fracture site, such as the nasal bone or other facial bone. 14,15 Hillstrom et al 14 introduced the concept of medial maxillary fractures in 1991 and defined the upper border of the fracture within the FPM. Yoshioka et al 15 recently revisited this idea and proposed that medial maxillary fractures are a particular type of nasomaxillary buttress fracture associated with the FPM and other surrounding structures.…”

Objective This study was performed to evaluate the clinical efficacy of endoscopic endonasal open reduction of fractures of the frontal process of the maxilla (FFPM). Methods We performed a retrospective study of patients who underwent endoscopic endonasal open reduction of FFPM from December 2013 to October 2018. The preoperative assessment included nasal endoscopy, computed tomography imaging, and three-dimensional craniofacial reconstruction. The clinical results were evaluated with a visual analog scale at 2 days and 1 year postoperatively. Results Thirty-two patients (25 male, 7 female) with an average age of 39 years were included in the study. All patients successfully underwent a surgical operation via the endoscopic endonasal approach with a nasal mucosal incision, and the nasal deformities were corrected. At the 1-year follow-up, six (18.8%) and 26 (81.2%) patients were somewhat satisfied and very satisfied with the aesthetic result, respectively, and five (15.6%) and 27 (84.4%) were somewhat satisfied and very satisfied with the functional result, respectively. Conclusion Endoscopic endonasal open reduction can be considered a reliable method for anatomical reduction of FFPM. This technology provides a viable choice for the treatment of FFPM.
