We described three cases of immediate reimplantation of a frozen-thawed autogenous mandible composed of a mixture of iliac bone, marrow, and particulate hydroxyapatite in tumors of the mandible. Acceptable outcomes were obtained in three patients who underwent immediate autogenous mandibular graft reconstruction. The conditions leading to successful outcome of the procedure are also discussed. Reimplantation of frozen autogenous lesioned mandible was performed in three patients with mandibular tumors. Two reimplanted grafts survived without complications following surgery. One case had postoperative infection that resolved with appropriate antibiotic treatment. There were no recurrences of the primary lesions. Satisfactory facial contour after surgery was achieved. These results are most promising, and we believe that, with further refinement, this technique will offer a new and acceptable modality for facial reconstruction in patients with cancer.

Three patients who underwent orthognathic surgery under general anesthesia complained about difficulty in vocalization and hoarseness after surgery. Intubation granuloma was diagnosed by the department of otorhinolaryngology in our hospital and the masses were excised by laryngoscopy assisted surgery. Chief complaints and symptoms of patients were relieved after surgery. These cases report with review of articles is presented, and the etiology, diagnosis, treatment and prognosis of intubation granuloma after orthognathic surgery are evaluated.

Background: The aim of this study was to understand the importance of professional oral care for inpatients by examining the type and frequency of surgery and hospital discharge period at dental hospitals, and identify the types of professional oral care actually in progress. Methods: In this study, the type of surgery and length of hospitalization were investigated among patients admitted to the dental hospital for oral and maxillofacial surgery, and the professional oral care status of inpatients who had difficulty self-managing their oral care was retrospectively identified by collecting data on oral care before and after surgery, including the type and frequency. Results: The majority of inpatients at dental hospitals were male (57.6%), elderly patients over 60 years accounted for 20% of patients, and the average length of hospitalization was 4 days. In the 20s (aged 20~29 y), the number of orthognathic surgery patients (73.1%) was high, and the incidence of cysts was high in middle-aged patients. Regarding the oral care of hospitalized patients, scaling was performed once by a dentist before surgery. After surgery, surgical dressings using H₂O₂ balls were applied and oral care education was introduced before discharge. Conclusion: Based on the results of this study, professional oral care is essential to prevent infection and complications caused by oral bacteria among inpatients at dental hospitals. It is necessary to use various oral hygiene aids for inpatients and to conduct effective oral care instruction according to each patient's situation. In addition, it is necessary to raise awareness and the role of dental hygienists in professional oral care.

Platelet-rich plasma is an autologous source of platelet-derived growth factor and transforming growth factor beta that is obtained by sequestering and concentrating platelets by gradient density centrifugation. We have used platelet-rich plasma for bone graft, especially allobone graft, at implant surgery, sinus lift procedure, and cyst enucleation. This article is retrospective study from October 1999 to November 2000. All cases were good healing and clinical success.

Temporomandibular ankylosis is defined as a situation in which the condyle is fused to the fossa by bone or fibrous tissue. Conditons such as trauma, infection, or systemic disease may predispose to various types of ankylosis, bringing about different levels of limitation in mandibular movement. Most patients with temporomandibular ankylosis are associated with limitation of maximal mouth opening, deviation of the chin toward the affected side, impaired occlusion, chronic pain, compromised oral hygiene, severe facial asymmetry & impeded mandibular molar eruption occurring in childhood. Several techniques to release ankylosis have been described in the literature, showing variable and often unsatisfactory results. The most frequently used operations are gap arthroplasty, interpositional arthroplasty, and exicision and joint reconstruction with autogenous or alloplastic materials. We have managed the two patients of TMJ ankylosis. They had previously TMJ surgery and we treated with gap arthroplasty & active physial therapy. We have obtained favorable results and report these cases with literatures review.

Purpose: This retrospective study evaluated the changes in hyoid bone and tongue positions as well as oral cavity volume after mandibular setback by BSSRO. Materials and Methods: 18 Koreans who underwent BSSRO to correct mandibular prognathism were studied. Lateral cephalograms were taken and traced preoperatively (T0), immediately (T1) and approximately 6 months postoperatively (T2). Submentovertex radiograghs were taken and traced before surgery (T0) and about 6 months after surgery (T2). The area and volume of oral cavity, the vertical and horizontal dimensions of the hyoid bone and tongue dorsum were measured. Results: Mandibular setback surgery resulted in a significant reduction of lower oral cavity volume. The hyoid bone displaced posteroinferiorly immediately after surgery, and it tended to return to its original vertical position at 6 month after mandibular setback by BSSRO. The retropalatal space around tongue was maintained and the retrolingual space around tongue was reduced immediately postoperatively. The readaptation of tongue was not evident for that the follow up period was not long enough. No significant statistical correlations between the amounts of mandibular setback and the changes of oral cavity volume were observed. Conclusion: Mandibular setback surgery resulted in a significant reduction of lower oral cavity volume, which was most likely attributable to the posterior movement of the mandible. More subjects and long-term observations should be performed to assess the changes of oropharyngeal configuration following mandibular setback surgery.
