STUDY DESIGN: A retrospective study. OBJECTIVES: To assess the relationship between surgical outcomes and preoperative MRI findings, a retrospective review was conducted on the surgical outcomes depending on the preoperative MRI findings including type of herniation and Modic changes. SUMMARY OF LITERATURE REVIEW: In most reports, the patients that have large disc herniation were expected to have improved surgical outcomes. However, there have been controversies regarding the outcomes and Modic changes. MATERIALS AND METHODS: The retrospective review was conducted in 82 patients who underwent a discectomy for single level lumbar disc herniation. The average follow-up period was 34.2 months. Among their preoperative baseline MRI measurements, the stage of disc herniation, degree of nerve root compression, degree of dural sac compression, and Modic change of vertebral endplate were evaluated for the subsequent comparison between the preoperative and postoperative changes and ODI score. RESULTS: Patients with extrusion or sequestration type showed significant improvements compared to the patients with protrusion type disc herniation. By degree of nerve root compression, patients with root compression showed significant improvements compared to the patients who had contact type. The degree of dural sac compression revealed no correlation with changes in the ODI score. 23 of the 82 patients, the preoperative MRI showed a Modic change. Compared to the group who did not show such a Modic change, they turned out to be unrelated to the preoperative and postoperative changes in the ODI score. CONCLUSIONS: Patients who had extrusion or sequestration type disc herniation showed a better clinical improvement than protrusion type. Patients with compression type root lesion showed better clinical improvement than contact type root lesion. No correlation was noted regarding the outcomes of the surgical treatment and degree of dural sac compression or Modic changes.

BACKGROUND AND OBJECTIVES: There has been a recent surge in the frequency of blowout fracture operations in the Department of Otorhinolaryngology. Clinical symptoms and signs, operative timing and the results from fracture site and size have been researched in this study. We conducted this study to examine the postoperative complications causing re-operation in orbital blowout fracture repair in the last seven years. SUBJECTS AND METHOD: Based on patients' clinical data, we retrospectively reviewed 160 patients who had operation because of blowout fracture from January 1998 to December 2004. Fifty-two patients had orbital floor, 74 patients had medial orbital wall, 34 patients had a combination of orbital floor and medial orbital wall fractures. We investigated diplopia, limitation of eye movements, and enophthalmos after the surgery, and analyzed the frequency and causes of re-operation. The mean postoperative follow-up was 24 months. RESULTS: We classified complications into immediate complications which occurred within 24 hours, late complications which occurred between 24 hours and 2 weeks, and delayed complications which occurred 2 weeks or more after operation. The symptoms of complications included diplopia, EOM limitation, cheek hypoesthesia, loss of vision, oroantral fistula, implant infection, ectropion, and etc. In case of sequelae which lasted more than six months, the combination of orbital floor and medial orbital wall fractures was higher than other fracture types. We carried out re-operation on 14 cases and the main cause was incomplete reduction. CONCLUSION: Surgeons should perform proper operation according to fracture site and type, and insert the implant after making an adequate dissection in order to reduce the frequency of complication and re-operation.

Frontal sinus fractures are relatively uncommon maxillofacial injuries, making up only 5% to 12% of all facial fractures. Management of the fracture depends on the type and severity of the fracture and the presence of associated injuries. The use of a metalic plate as a reduction material for facial bone fracture has vastly grown; however, in infants, metal implants induce growth restriction of facial bone and the plate needs to be removed after approximately 3-6 months. Due to these weakness, the use of it as a bioabsorbable plate has thus taken over the large proportion of all its uses. A 15-year-old man was admitted to our hospital with a depression fracture of the frontal sinus anterior wall after trauma to the frontal area. Seven days after the trauma, the patient got open reduction. After exposing the fracture site with a butterfly incision, and placing the fractured bony fragments back in original place, the bioabsorbable plates were fixed on them. Postoperatively, depressed frontal area was restored normally. There is no evidence of complication after 28 months from the operation. We report a successful reduction of the frontal sinus anterior wall fracture using bioabsorbable plates.

The incidence of intracranial complications of otitis media, including lateral sinus thrombophlebitis, has been significantly reduced since the advent of antibiotics. This entity is rarely encountered in clinical practice, and delay in its diagnosis and institution of appropriate therapy may lead to serious, or even fatal, consequences. The signs and clinical course of lateral sinus thrombophlebitis are non-specific and the final diagnosis rests upon radiological investigations including CT-scans and MRI. We have experienced a case of middle fossa and posterior fossa epidural abscess formation, lateral sinus thrombophlebitis that has developed secondary chronic otitis media with cholesteatoma in a 47 year-old female patient. We report this case which was successfully treated by middle fossa dura and posterior fossa dura drainage, lateral sinus thrombectomy with open mastoidectomy.

Ciliated hepatic foregut cyst (CHFC) is a rare benign lesion consisting of ciliated pseudostratified columnar epithelium, loose subepithelial connective tissue, a smooth muscle layer, and an outer fibrous capsule. We encountered a patient with retroperitoneal and posterior mediastinal neurilemmoma and additional CHFC mimicking metastasis. Abdominal CT examination demonstrated that the posterior mediastinal and retroperitoneal lesions were lobulated, well-defined tumors with a neural foraminal extension that were pathologically confirmed as neurilemmomas. Unenhanced CT indicated that the additional lesion was a slightly hypodense mass relative to surrounding parenchyma at the medial segment of the left lobe of the liver, and after the IV ad-ministration of contrast material, the lesion did not show enhancement.
