The interpretation of MRI of partial-thickness rotator cuff tears can be challenging. This review describes the anatomic considerations for diagnosing partial-thickness tears, especially supraspinatus and infraspinatus tendon and summarizes the classification of partial-thickness rotator cuff tears, as well as provides an overview on partial-thickness tears with delamination.

PURPOSE: This study was undertaken to describe the clinicopathologic characteristics and evaluate the appropriate management of appendiceal tumors. METHODS: During 5 years between Sep. 2000 and Sep. 2005, 28 appendiceal tumors were identified in a retrospective review of 3,744 cases of appendectomy or right hemicolectomy pathology. RESULTS: Carcinoids were found incidentally as appendicitis. Mucinous cystadenomas were common in women older than 50 aged; half of the cases presented with appendicitis and the other half presented with non-specific abdominal symptoms such as palpable mass, intestinal obstruction and intussusception. Carcinomas were common in the older patients (mean age: 62.8 years) and this presented as periappendiceal abscess. Right hemicolectomy was undertaken when there was evidence of tumor spread beyond the resection margin, and carcinoma and tumors were located in the appendiceal base. Recurrence and metastasis were identified only in the carcinoma cases. CONCLUSION: Most appendiceal tumors presented with appendicitis and periappendiceal abscess. One stage curative resection was possible in more than 76% of the patients, and the prepoperative diagnosis rate was less than 35%. The preoperative diagnosis did not have much impact on the clinical course, and the postoperative pathology was important in determining the additional treatment. Close follow-up is needed for the early detection of recurrence, and all the carcinomas that were advanced as serosal involvement, peritoneal seeding and liver metastasis.

Carcinoma ex pleomorphic adenoma is transformed at the incidence of 1-20% in pleomorphic adenoma and frequently recurred. It accounts for 10% of all malignant salivary tumors and its average age of occurrence is 60s. It will present in a large, long-standing pleomorphic adenoma or in one that was previously treated but has recurred. According to cell composition in malignant cell carcinoma, and clear cell adenocarcinoma. Most (75%) occur in parotid gland, while about 20% occur in the minor gland of the oral mucosa. The metastasis rate to regional lymph node is about 25%, and to distant organs about 33% and the 5-year survival rates are 40%. Though the treatment of the carcinoma ex pleomorphic adenoma is not established, it is treated ideally with and extensive resection, neck dissection, postoperative radiotherapy, and chemotherapy. When occurred in parotid gland, facial paralysis is reported. With a review of literatures, we report a case of carcinoma ex pleomorphic adenoma which operated with total parotidectomy and supraomohyoid neck dissection.

PURPOSE: The classic technique for open reduction of subcondylar fractures is the submandibular approach. The aim of this study was to evaluate clinical result of retromandibular approach to displaced subcondylar fractures. MATERIAL AND METHODS: During a period of 24months we perfomed a prospective study with a retromandibular approach in 23 paients with displaced subcondylar fractures. In this article we describe clinical result in 23 patients with follow ups for 3 months after surgery. Preoperatively all patients had malocclusion and radiology demonstrated displacement. RESULT: The retromandibularl approach for ORIF was good in all case. Mouth opening(M/O) was 49mm. Occlusion was good too. Permanent facial nerve palsy was not detected. CONCLUSION: Our findings indicate that the retromandibular approach is a safe technique for subcondylar fractures.

PURPOSE: The aim of this study was to examine the incidence, location and morphology of antral septa using radiographic exam.(Panorama, CT) in the dentate/non-atrophic and edentulous/atrophic maxillary segments. MATERIAL AND METHODS: 232 sinuses were subdivided into two groups(group1 : 175 sinuses were classified as complete & partial dentate maxillary segments, group2 : 57 sinuses were classified as complete edentulous maxillary segments) and were investigated for the incidence, location and morphology of maxillary sinus septa. RESULTS: A total of 80 septa were observed in 232 maxillary sinuses, which corresponded to 30.65% of the sinuses(71 of 232). 67.5% of the total septa was observed in the complete & partial dentate groups, but 32.5% of the total septa was observed in the complete edentulous group. Upon analysis of the anatomical location of the septa, it was seen that 14 septa(17.5%) were located in the P1 area, 15 septa(18.7%) were located in the P2 area, 19 septa(23.8%) were located in the M1 area and 32 septa(40%) were located in the M2 area and dista area of M2. we found 45 septa in the apical lesion of teeth, Group 1. However the remaining 9 septa were found in the edentulous area. CONCLUSION: CT is a better method than panoramic radiography for detecting the presence of the maxillary sinus septa. Maxillary sinus septa are more commonly detected in complete edentulous maxillary segments than in complete and partial dentate maxillary segments. Also maxillary sinus septa are more commonly detected posteriorly than anteriorly.

The incidence of aspergillosis infections in the maxillary sinus has increased recently, because of overuse of antibiotics, steroids, anticancer agents, immunosuppressant, antimetabollites, and uncontrolled diabetes mellitus. The clinical features of maxillary sinus aspergillosis include pain, swelling and foul odor nasal excretion. This needs to be differentiated from bacterial maxillary sinusitis, and surgical treatment with antifungal agents are suggested. Recently, we treated two patients with maxillary sinus aspergillosis surgically (Caldwell Luc operation) and with antifungal agents(itraconazole). The results were satisfactory so we report these cases with literature review.

A 65-year-old male was referred to our hospital for evaluation of a right pleural effusion. Thoracic computed tomography (CT) revealed a huge central mass with right hilar and subcarinal lymph node conglomerates. An endobronchial mass was incidentally found in the right upper lobe bronchus, and endobronchial ultrasound-guided transbronchial needle biopsy of the mediastinal lymph nodes was thus also performed at the time of bronchoscopy. The two biopsies revealed squamous cell carcinoma and diffuse large B-cell lymphoma (DLBCL), respectively. As the pathology of the mediastinal lymph nodes was unknown, the lung cancer could not be accurately staged. Thus, we treated the DLBCL; follow-up positron emission tomography/CT after two cycles of chemotherapy showed that the conglomerate mass had disappeared but the right upper lobe lesion remained. Lung cancer staging thus became more accurate and radical treatment could be considered. To the best of our knowledge, this is the first report of a co-existing squamous cell carcinoma of the lung and DLBCL of the intrapulmonary lymph nodes.
