Purpose: The anterior iliac crest is a common source for autologous cancellous bone graft. For patients who have previously received cancellous bone grafts from bilateral anterior iliac crests, there may be concerns of whether a sufficient quantity of autologous cancellous bone remains for additional grafts without harvesting it from other sites, such as the posterior iliac crest. Methods: We experienced 3 cases of reharvesting in 2 patients. The diagnosis of the first patient was bilateral facial cleft number 3. This patient received bilateral side cleft alveoloplasty with corticocancellous bone graft from the both anterior iliac crest respectively by a previous surgeon. This patient then needed reharvesting of the anterior iliac crest cancellous bone to correct an ongoing skeletal problem for the bilateral cleft. The other patient had bilateral incomplete cleft of the primary palate. This patient received left side cleft alveoloplasty with cancellous bone graft from the right anterior iliac crest. Before the patient could receive the alveoloplasty on the other side, a radial head osteotomy and cancellous bone graft was performed by orthopedic surgeons who then used the remaining left iliac crest in order to treat a pulled elbow. For the completion of the right side cleft alveoplasty, the anterior iliac crest cancellous bone needed to be reharvested. Prior to the reharvesting, a preoperative computed tomography scan of the pelvis was obtained to assess the maturity of the donor site regeneration. The grafts were then taken from site where a greater amount of regeneration was evident. Results: Long term follow ups showed that the grafts were successfully taken. This sufficient volume was obtainable 14 months after the first harvest. Conclusion: Satisfactory results were achieved after the reharvesting of iliac cancellous bone. Thus, it appears that the reharvesting of the iliac bone is a possible alternative to multiple site grafting, use of allograft or bone substitute materials.

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation. With the biopsy and computed tomography, it was confirmed that fistula and basal cell carcinoma. However, the connection between the fistula and skin cancer was not clear. Positron emission tomography-computed tomography scan was performed and was not detected as other local or distant metastasis. After that, wide excision of the skin lesion was performed. Although skin cancer is not commonly observed, it is necessary to rule out this disease entity by performing biopsy of skin lesions.

Osteomas are benign, slow-growing osteogenic lesions frequently found in the craniomaxillofacial region. They can be classified as peripheral, central, or extraskeletal. Reactive mechanisms to trauma or infection, as well as muscle traction, are thought to play a major role in the development of peripheral osteomas. In the present report, a 41-year-old woman presented with a slowgrowing, painless mass on her left eyebrow. She had suffered trauma 15 years prior. In the computed tomography scan, a 2.5×2×0.7-cm radio-opaque tumor was detected just medial to the left supraorbital foramen, and a peripheral osteoma was clinically diagnosed. An elective operation under general anesthesia was planned. Following a suprabrow incision, subcutaneous and intramuscular dissection was performed. In the surgical plane deep to the corrugator muscles and superficial to periosteum, a branch of the supratrochlear nerve was encountered and preserved using a vessel loop. The osteoma beneath the periosteum was extracted in multiple fragments using a chisel and mallet to minimize trauma to the nerve. Contour and facial symmetry were corrected. To use a suprabrow incision, the surgeon must understand neighboring anatomical structures, including the course of the supratrochlear and supraorbital neurovascular bundles. When these structures are located adjacent to tumor lesions, careful surgical maneuvers should be performed to preserve them.

Purpose: Blow-out fracture is one of the most common fractures in facial trauma. It is diagnosed by Computed Tomography(CT) scan, which is considered as the most effective diagnostic tool. Since, the Picture Archiving Communication System(PACS) has been provided recently to many hospitals, doctors are more familiar with imaging software of PACS. Because this software has many useful measuring tools, doctors can measure orbital structure easily and make a plan for treatment with its data. Therefore, authors intended to analyze the data of orbital structure measured with PACS imaging software and evaluate its usefulness. Methods: The charts and CT images of 100 patients, which were 50 patients with medial wall fracture and 50 patients with floor fracture, were reviewed. Patients were selected by pre-determined criteria and their CT images were measured with image software of PACS. 'Extraocular muscle thickness', 'Defect ratio'(ratio of defect area to normal area) and 'Globe position index' were measured and analyzed statistically. Results: The thickness of inferior rectus muscle and medial rectus muscle was simultaneously increased in acute-stage of blow-out fracture. The medial rectus muscle was more thickened in medial wall fracture and inferior rectus was more thickened in floor fracture, respectively. In acute blow-out fracture, globe position is exophthalmic rather than enophthalmic. Especially in floor fracture, numerical value summed up thickness of all extraocular muscle is correlated to the defect ratio and globe position index. Conclusion: Clinicians can decide globe position or presume defect ratio in inferior wall fracture by measurement of CT image in acute blow-out fracture using PACS.

Fungal sinusitis is relatively rare, but it has become more common in recent years. When fungal sinusitis invades the orbit, it can cause proptosis, chemosis, ophthalmoplegia, retroorbital pain, and vision impairment. We present a case of an extensive orbital floor defect due to invasive fungal sinusitis. A 62-year-old man with hypertension and a history of lung adenocarcinoma, presented with right-side facial pain and swelling. On admission, the serum glucose level was 347 mg/dL, and hemoglobin A1c was 11.4%. A computed tomography scan and a Waters' view X-ray showed right maxillary sinusitis with an orbital floor defect. On hospital day 3, functional endoscopic sinus surgery was performed by the otorhinolaryngology team, and an aspergilloma in necrotic inflammatory exudate obtained during exploration. On hospital day 7, orbital floor reconstruction with a Medpor Titan surgical implant was done. In principle, the management of invasive sino-orbital fungal infection often begins with surgical debridement and local irrigation with an antifungal agent. Exceptionally, in this case, debridement and immediate orbital floor reconstruction were performed to prevent enophthalmos caused by the extensive orbital floor defect. The patient underwent orbital floor reconstruction and received intravenous and oral voriconazole. Despite orbital invasion, there were no ophthalmic symptoms or sequelae.

하악 수술로 치료한 골격성 3급 부정교합 환자의 연조직 변화를 3차원적으로 분석하였다. 수술전과 수술후에 CT를 촬영하고, 연조직과 경조직을 각각의 임계값에 따라 segmentation였다. FH.평면, 정중시상면, PNS를 포함하는 전두면을 기준으로 공통 좌표계를 구성하고, 이 좌표계를 기준으로 술전, 술후 영상을 위치시켰다. 술후의 변화를 측정하기 위해 각각의 모형에 대해 전두면에 평행한 grid를 형성하였다. Grid내의 교점에서 골조직과 연조직 모형에 투사하여 만나는 점의 좌표값을 구하고, 이를 바탕으로 술후의 변화를 측정하였다. 하악골 후퇴술시 안모의 변화는 하악골 부분에서만 발생한 것이 아니라, 구각부에서도 관찰되었다. 하악골 부위의 연조직 변화는 대응되는 골조직 이동량에 따른 상대적인 값으로 계산하였다. 정중시상면에서의 변화율은 $77\~102\%$로 나타났다. (p<0.05). 정중시상면 이외의 부분의 변화양상도 이와 유사하였다. 구각부에서의 변화는 하악골의 이동을 대표할 수 있는 점의 이동량에 대한 상대적인 값으로 계산하였다. 정중시상면에서의 변화는 B점을 기준으로 $14\~29\%$이고, Pog점을 기준으로 $17\~37\%$, grid상 83번째 점을 기준으로 $11\~22\%$로 관찰되었다.(p<0.05)

Background: The location of parotid gland tumors can influence the duration and the difficulty of the operation. If the information about tumor location was available preoperatively, it would allow accurate operative planning and counseling of patients in terms of the length of the operation and the potential morbidity. Methods: This study was based on a retrospective review of 100 patients with parotid gland tumors underwent parotidectomy from January 2000 to October 2005 at Yong-Dong Severance Hospital. Based on computed tomographic(CT) scan findings, 4 landmarks such as facial nerve(FN) line, Utrecht(U) line, Conn's are(CA), and retromandibular vein (RV) were drawn on the scans in same plane. The location of tumors were determined by the landmarks and confirmed by the operative findings. The accuracy of each landmarks was evaluated. To find out the accuracies according to tumor size, the tumors were divided into 2 groups; less than 2 cm and larger than 2 cm in diameter. Results: U line was the most accurate(94%), sensitive(89.3%) and specific(97.7%) in predicting tumor location of the parotid gland. However, in small tumors less than 2cm, FN line (p=0.022) and RV criteria (p=0.028) were more reliable in accuracy. Conclusion: CA, FN line, U line, and RV are all useful landmarks in preoperative prediction for the location of parotid gland tumors. However, U line was the most accurate, but we must consider that proper landmark should be used in prediction according to the size of tumor because the accuracy of landmark may change.
