The purpose of this retrospective study was to evaluate relapse, comparing large and small maxillary advancements with four-plate rigid fixation and without bone grafting. All patients had skeletal class III malocclusion, and underwent bimaxillary surgery. Standardized cephalometric analysis by one examiner was performed on serial radiographs of 14 patients immediately before surgery, and within 1 week and at least 6 months postoperatively (mean 10 months). The group was divided into two subsets to determine whether the magnitude of relapse. In group 1 ($\leq$ 5 mm, n = 8), the average advancement was $4.0{\pm}0.9\;mm$, with a mean relapse of $0.1{\pm}0.5\;mm$. In group 2 (6-8 mm, n = 4), the average advancement was $6.8{\pm}0.9\;mm$, with a mean relapse of $0.7{\pm}0.4\;mm$. There was no statistical difference in the measured relapse among the groups. Maxillary advancement with a 1-piece Le Fort I osteotomy is a relatively stable procedure.

Purpose: We report the radiologic and the clinical results for surgical treatment of calcaneal fractures involving the subtalar joint. Methods: We evaluated the findings of radiographs and computed tomographs of 39 patients (40 cases) with intra-articular calcaneal fractures. The fractures were treated with open reduction via an extended lateral approach and internal fixation using a plate. We assessed the radiologic results, such as the $B{\ddot{o}}hler$ angle, the Gissane angle, and the height/width ratio. We assessed the clinical results based on the critieria of Salama et al. Results: According to the Essex-Lopresti classification, 9 cases were classified as tongue type and 31 cases as joint depression type. According to the Sanders classification, 10 cases were classified as type IIA, 4 cases as IIB, 16 cases as IIIAB, 4 cases as IIIAC, and 6 cases as type IV. The mean preoperative $B{\ddot{o}}hler$ angle was 7.7, the mean postoperative $B{\ddot{o}}hler$ angle was 21.1, and the mean last follow-up $B{\ddot{o}}hler$ angle was 16.8. Clinical results classified as 10 excellent, 13 good, 11 fair, and 6 poor. Conclusion: In the treatment of intra-articular fractures of the calcaneus, open reduction via an extended lateral approach seems to be a useful method in that it can provide direct exposure of the subtalar joint with little morbidity.

The authors report a very rare case of tuberculous spondylitis combined with a schwannoma of spinal cord. A 39- year-old man was admitted because of paraparesis(G1/G2). MRI showed severe cord compression at two different levels. One was by the bulged soft tissue and subligamentous abscess extending from T7 to T9 and the other was by an intradural extramedullary cord tumor at the level of T1-2. At first operation, T8 corpectomy and T7-9 plate fixation with autogenous iliac bone graft were performed. After then, Paraparesis was improved(G2/G3) postoperatively. The second operation underwent two weeks later. The tumor was totally removed and shortly after second operation, paraparesis was markedly improved(G3/G4). Histological diagnosis were tuberculous spondylitis and schwannoma, respectively. The authors reviewed this case where good surgical outcome was obtained by two stage operation.

Objectives: Transpositioning of the inferior alveolar nerve to prevent injury in lower jaw has been advocated for orthognathic, pre-prosthetic and for implant placement procedures. However, the concept of infra-orbital nerve repositioning in cases of mid-face fractures remains unexplored. The infraorbital nerve may be involved in trauma to the zygomatic complex which often results in sensory disturbance of the area innervated by it. Ten patients with infraorbital nerve entrapment were treated in similar way at our maxillofacial surgery centre. Materials and Methods: In this article we are reporting three cases of zygomatico-maxillary complex fracture in which intra-operative repositioning of infra-orbital nerve into the orbital floor was done. This was done to release the nerve from fractured segments and to reduce the postoperative neural complications, to gain better access to fracture site and ease in plate fixation. This procedure also decompresses the nerve which releases it off the soft tissue entrapment caused due to trauma and the organized clot at the fractured site. Results: There was no evidence of sensory disturbance during their three month follow-up in any of the patient. Conclusion: Infraorbital nerve transposition is very effective in preventing paresthesia in patients which fracture line involving the infraorbital nerve.

This study was performed in order to evaluate the occurrence of temporomandibular joint disorder after surgical correction of skeletal class II malocclusion. Materials and Methods: This study included 21 patients who underwent orthognathic surgery for the correction of dentofacial deformities by a single surgeon at Mokdong Hospital, Ewha Womans University from 2000 to 2010. They underwent bilateral sagittal split ramus osteotomy for the treatment of undesirable mandibular advancement. The temporomandibular disorder (TMD) symptoms prior to surgery were recorded and the radiographic evaluation (panorama, bone scan, and magnetic resonance imaging [MRI]) of the post-surgery temporomandibular joint (TMJ) were assessed in order to evaluate condylar resorption, remodeling and disc displacement. The minimum follow-up period, including orthodontic treatment, was 12 months. Orthognathic procedures included 1-jaw surgery (n=8 patients) and 2-jaw surgery (n=13 patients). The monocortical plate was used for bilateral sagittal split ramus osteotomy fixation. Results: Among class II malocclusion patients with TMD symptom, clicking improved in 29.1%, and maximum mouth opening increased from $34.5{\pm}2.1$ mm to $37.2{\pm}3.5$ mm. The differences were not statistically significant, however. Radiographic changes in bone scan improved slightly based on the report by radiologist but not in TMJ dynamic MRI. Conclusion: No particular improvements were found in patients with joint sound only. Patients with limitation of mouth opening showed an increase in the degree of opening, but the difference was not statistically significant (P>0.05).

Purpose: Mandibulotomy approach and mandible sparing approach are most common methods for oropharyngeal cancer surgery. Good surgical view and convenience of flap inset are advantages of mandibulotomy approach but deformity of mandible contour, postoperative malocclusion and radionecrosis are its limitations. To make up for the limitations, mandible sparing method is commonly performed, but limited surgical view and difficulties of flap inset are the weak points of this approach. The purpose of the study is to compare mandibulotomy and mandible sparing approaches in postoperative complications and progression of the treatment in oropharyngeal cancer operation and reconstruction. Methods: Single reconstructive microsurgeon operated for oropharyngeal cancer patients with different surgeons of head and neck department who prefer mandibulotomy and mandible sparing approach respectively, and we compared the frequency of postoperative complication, operation time, duration of hospitalization and recurrence rate between two different surgical approaches. Results: Mandibulotomy approach was used in 18 patients and mandible sparing approach was used in 15 patients. In mandibulotomy approach, there happened one case of teeth injury and one case of necrosis of skin and gingiva, but there happened no malocclusion and radionecrosis. In mandible sparing approach, there were 3 cases of fistula and 2 cases of infection which are significantly higher than mandibulotomy approach. There were no significant differences between early regional recurrence and duration of hospitalization. Conclusion: In this study we compared two different methods for the surgical approach in oropharyngeal cancer surgery. As mandible sparing approach has difficulties of limited surgical view, it can be used for the limited indications of anterior tongue and mouth floor cancer. Mandibulotomy approach has advantages of good surgical view and convenience of flap inset. In this method preservation of gingival tissue, watertight fashion suture, delicate osteotomy and plate fixation to maintain occlusion are the key points for the successful results.

Background: The aim of this study was to assess the clinical outcomes after treatment of proximal humeral fractures with locking plates, and to determine which factors influence the clinical and radiological outcomes. Methods: Fifty six patients who were treated with locking plates for proximal humeral fractures and had been followed for more than 1 year were enrolled in this study. We performed functional evaluation using the Constant score and analyzed radiographic results. The following factors that may potentially influence the clinical outcomes were assessed: age, gender, type of fracture, presence of medial metaphyseal comminution, bone mineral density, anatomical reduction, restoration of medial mechanical support, and postoperative complications. Results: The mean Constant score was 70.1 points at the final follow-up. Female gender, 4-part fractures, AO type-C fractures, and fractures with medial metaphyseal comminution were associated with a poor clinical outcome. On the other hand, restoration of medial mechanical support and accurate anatomical reduction had a positive influence on clinical outcomes. Postoperative complications resulted in 3 patients (intra-articular screw perforation: 1 patient, varus deformity with screw loosening: 1 patient, nonunion: 1 patient). Conclusions: When treating proximal humeral fractures with locking plate fixation, following factors: a female gender, Neer type 4-part fracture, AO type C fracture, and medial metaphyseal comminution are important risk factors that surgeons should take into consideration. Factors that contribute to better clinical outcomes of operative treatment for humeral fractures are accurate anatomical reduction and restoration of medial mechanical support.
