These is a cases of chronic suppurative osteomyelitis occurred in the mandibular body to condyle of 48-year-old male patient. Extensive bone destruction was noted on the right mandibular body, angle, ascending ramus, mandibular notch and condylar region. We made a treatment plan that radicular mandibular resection from body to condyle and mandibular reconstruction with vascularized fibular flap at first time. But, we could observe marked bone regeneration with only mild curettage, local wound care and massive antibiotic therapy. So we preserved the anterior ramus portion of mandible. Defected mandibular condyle was reconstructed with costochondral graft. In this paper we present the case of a patient who has chronic osteomyelitis in mandibular area.

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, occurs commonly in the soft tissues in adult, but is rare in the maxillofacial region. It consists of undifferentiated mesenchymal tumor cells resembling histiocytes and fibroblasts. The purpose of this article is to report a case of UPS in the mandible. A 44-year-old patient presented with a painful growing mass in the mandible of two months' duration. Computed tomography and positron emission tomography-computed tomography revealed an ill-defined heterogenous, hypermetabolic mass about 4 cm in size in the left mandible invading adjacent soft tissues. A left mandiblulectomy and reconstruction with a fibular free flap were performed. Immunohistochemical study gave a diagnosis of UPS. The patient was referred for adjuvant chemotherapy after surgical removal of the tumor.

Xanthoma is a localized collection of tissue histocytes containing lipid. The majority of tendinous xanthomas probably occurs in the setting of hypercholesterolemia especially in bilateral Achilles tendon xanthomas. Xanthoma of the Achilles tendon is a rather rare, interesting orthopaedic condition that has important ramifications in internal medicine and dermatology because the lesion is associated with a specific disturbance of lipid metabolism. We experienced one case of normolipidemic and symptomatic Achilles tendon xanthoma. Surgical intervention was carried out for cosmetic and symptomatic reasons, the patient undergoing total resection and a reconstruction of the Achilles tendon by the combinedV-Y muscle flap and modified Lindholm technique.

Melanoma of the scalp is rare condition and seems to be to have a poor prognosis than melanoma of other portion of the body. We had 2 patients suffering from malignant melanoma of scalp. Their charts were reviewed for epidemiologic data, location, Breslow thickness, lymph node involvement and outcome. The therapeutic treatment was wide excision and skin grafting or free flap reconstruction. The early recognition of all the nevi at scalp and proper follow-up of the lesion are key stones to eradicating the changing mole and to preventing this thread to life.

Multilayered cartilage graft has been clinically used at tip plasty, total ear reconstruction, and cleft lip nasal deformities. Perichondrial flap or a free perichondrium has been also commonly used for induction of neocartilage. However, the influence of perichondrium on multilayered cartilage graft to strength and growth rate is still unknown. The purpose of this study was to compare the strength and growth rate of different multilayered cartilage graft and to present the most ideal model of multilayered cartilage graft. Twenty New-zealand white rabbit were used. Triple layers of cartilage grafts with various perichondrium were inserted into six separate pockets in paravertebral region of rabbits. The grafts were grossly and microscopically observed on 8 and 16 weeks after grafting. On gross observation, the grafts showed marked enlargement of three layers of cartilage grafts with perichondrium compare with three layers of cartilage grafts without perichondrium In histologic examination, the number of PCNA-labelled cells were significantly high on three layers of cartilage grafts with perichondrium. In conclusion, this study suggested that triple-layer graft of cartilage grafts with perichondrium on the outside of triple-layer graft has strength and an effect on chondrogenetic induction by the perichondrium.

Necrotizing sialometaplasia was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory process involving minor salivary glands. Prior to recognition of necrotizing sialometaplasia as a benign, self-limited lesion, it was all too often diagnosed as either squamous cell carcinoma or mucoepidermoid carcinoma and had been improperly treated because of its clinical and histological resemblance to malignancy. We report two cases of necrotizing sialometaplasia. One case involved a 56-year-old female who developed a necrotizing sialometaplasia in association with palato-pharyngeal flap wound after excision of soft palate cancer and reconstruction. Another case involved a 55-year-old male who had a soft palate mass.

Objective : Traditionally, standard access to the posterior fossa was a suboccipital craniectomy. After introducing the technique and benefit of posterior fossa craniotomy, several surgeons have used this procedure to manage various pathologies in posterior fossa in children. Though this approach offers several advantages over conventional suboccipital craniectomy, the elevation of bone flap is not easy in adult because of the irregular contour of inner bone surface and tight adhesion of dura to the skull. The aim of this article is to describe the technical aspects of this approach and to delineate the important landmarks for a safe and quick performance in adult. Methods : We report on our series of twenty-five adult patients who underwent craniotomy for posterior fossa pathologies between 2002 and 2005. The maximal follow-up period was 4 years. Results : None of the patients complained of persistent headache and no CSF leaks have occurred postoperatively. We have encountered only two cases of transient subcutaneous CSF retention after craniotomy. Three-dimensional reconstruction of the CT scan confirmed the well-fitted suboccipital bone contour after craniotomy. And patients were satisfied with the cosmetic results. Conclusion : This method is safer and simpler. It restores normal anatomical planes and improves protection of the contents of the posterior fossa. The authors recommend craniotomy as an alternative method of access to the posterior fossa in all age groups.

Chondrosarcoma is a malignant tumor that originates from cartilaginous cells and is characterized by cartilage formation. Only 5% to 10% of chondrosarcoma occurs in the head and neck area, and it is uncommon in the temporomandibular joint area. This report describes an unusual case with a rare, large chondrosarcoma in a 47-year-old woman who presented with painless swelling and trismus. Computed tomography showed a large mass approximately $8.5{\times}6.0$ cm in size arising adjacent to the lateral pterygoid plate and condyle. There were features suggestive of bone resorption. The tumor was resected in a single block with perilesional tissues, and a great auricular nerve graft was performed because of facial nerve sacrifice. Microscopic examination of sections stained with H&E revealed chondrocytes with irregular nuclei and heterogeneous hyper chromatic tumor cells embedded in the chondrocyte lacuna. The diagnosis was a grade I chondrosarcoma. There was no evidence of recurrence at the 8-month follow-up, and a reconstruction surgery with fibular osteocutaneous free flap was performed. We report this unusual entity and a review of the literature.

The common causes of neck closed injuries are automobile accidents and sports troubles; open injuries are gun-shot wounds and stab wounds. Generally, the treatment of wide laryngopharyngeal injuries consists of tracheostomy for adequate airway, simple repair and, later, surgical intervention for chronic laryngeal stenosis and hypopharyngeal reconstruction. Recently, authors experienced a case of extensive communicated wound with large defect on the layngopharyngeal structures and anterior neck skin. This large defect was reconstructed with horizontal cervical skin flap after total laryngectomy.

Secretory carcinoma of salivary gland origin is a recently described tumor that harbors a characteristic ETV6-NTRK3 translocation that is identical to secretory carcinoma of the breast. The majority of tumors were located in the parotid gland and other major salivary glands, while the minority occurred in a minor salivary gland. We present a case of a 71-year-old female who was diagnosed with low-grade salivary gland cancer presenting in the soft palate accompanying lymph node metastasis. Peroral wide excision, selective neck dissection, reconstruction with radial forearm free flap was performed. The final pathology report indicated secretory carcinoma of the soft palate. The patient was followed-up without evidence of recurrence for one year. At present, it is difficult to accurately assess prognosis and treatment for the secretory carcinoma of the minor salivary gland origin. Continuous follow-up with various cases is needed further.
