The Successful Reduction of an Anterior Maxillary Fracture with Foley Catheter and Real-Time Ultrasonography / 대한이비인후과학회지

Maxillary fractures are common traumas in facial lesions, frequently involving the thin bony anterior wall. Minimally invasive operations have been tried in these maxillofacial areas; for example, the Foley balloon inflation technique guided by nasal endoscopy in orbital blow-out fractures have been recently reported with a high success rate. However, in maxillary anterior wall fractures, these minimally invasive surgical procedures have seldom been reported. This report presents the case of a 24-year-old man with an anterior maxillary wall fracture. The fracture was treated with a minimally invasive method that uses an endoscopic approach to the maxillary antrum with a Foley catheter ballooning, which was monitored by real-time ultrasonography. This report presents the imaging studies and a description of the endoscopic procedure.

A Case of Paraffinoma Removal Using Endoscope-Assisted Microdebrider

Paraffin has been used illegally in Korea for many years as an oil-soluble substance to augment depressed nasal dorsum. Here we describe the successful management of a case of nasal paraffinoma using an endoscope-assisted microdebrider and primary reconstruction using autologous dermofat and Gore Tex. The patient was placed in the supine position under general anesthesia, and bilateral intercartilaginous incisions were made. The endoscopic views provided an extended image that aided in identifying paraffinoma within the soft tissue. The paraffinoma was removed with a microdebrider. The dorsal defect and irregularities were reconstructed using dermofat and Gore-Tex.At the four-year follow-up, the patient was satisfied with the cosmetic results, and there was no evidence of recurrence.

Radiologic and Histological Study of Healing Process on Malunion Rat Model after Zygomatic Arch Fracture

BACKGROUND AND OBJECTIVES: Zygomatic arch fracture should be treated early, because failure of prompt treatment of these injuries November result in significant morbidity, including malar asymmetry, enopthalmos, and sensory deficits. The purpose of this study was to evaluate the radiologic and histological changes of healing process on zygomatic arch fracture with malunion in animal model. MATERIALS AND METHOD: Ten rats with malunion after zygomatic arch fracture were used in this study. Using micro computerized tomography, we evaluated the defect of fracture site with serial weeks (1, 2, 4, and 8). We also analyzed the histological findings at same period. RESULTS: The 2-D images were able to assess a difference in recovery process of a bone fracture, but it was too small to be recognized. However, we could find to the definite changes of healing process by using the 3-D reconstructed image according to time sequence. Additionally, fracture sites were healed by primary bone healing process in the zygomatic arch fracture malunion state. CONCLUSION: The 3-D image is more useful to evaluate for fracture healing state. Moreover, the proper evaluation and adequate management is necessary even after eight weeks, because healing of fracture was not completed.
