Purpose : To review developmental salivary gland defect based on 12 reported cases and literature, and to guide radiographic diagnosis of this entity. Materials and Methods : The 12 cases of developmental salivary gland defect of Chosun University Dental Hospital in the last 4 years were analyzed and compared with previous reported cases. Result : 11 of the 12 cases were found in men, indicating a very strong male predilection. The peak age was in the 6th decade. These defects were situated just above or at the inferior border of mandible between the first molar and the mandibular angle, and always Inferior to the mandibular canal. Only one case was superimposed with the mandibular canal, 6 cases were superimposed with the inferior border of the mandible. Conclusion : Characteristically, these defects had a special radiographic features such as ovoid shaped well-defined radiolucency located just above or at the inferior border of the mandible between the first molar and the mandibular angle, and always inferior to the mandibular canal. The recognition of these radiographic features were diagnostically valuable.

Inferior alveolar nerve block anesthesia is one of the most common procedures in dental clinic. Although it is well known as safe procedure, complications always can be occurred. Ocular complications such as diplopia, loss of vision, opthalmoplegia are very rare, but once it happens, dentist and patient can be embarrassed and rapport will be decreased between them. We experienced one diplopia case after inferior alveolar nerve block anesthesia and treated without any further complication. We report this case and describe the cause, diagnosis, and treatment objectives of diplopia caused by inferior alveolar nerve block anesthesia.

This study was carried out to investigate a point of difference between normal and inferior Korean red ginseng (Naeback red ginseng = red ginseng with white part of clear boundary in phloem and/or xylem of ginseng body, saengnaeback red ginseng red ginseng with white part of indistinct boundary). White part with clear or indistinct boundary in center of ginseng body was observed in inferior red ginseng (naeback and saengnaeback red ginseng), and the differences in the internal color intensity was also found with naked eye. In hunter color values of normal and inferior parts of red ginseng in accordance with particle size, L value was increased with a diminishment in particle size, while a and b value were decreased. Absorbance at visible spectrum did not differ from water and 70% ethanol extract from normal and inferior parts of red ginseng, but absorbance in UV spectrum of extract from naeback part showed higher than those of normal and saengnaeback part. In comparison of intrastructure by electron microscope, the horizontal and vertical section of cortex and pith layer from normal part showed the very dense state, but small holes were found in naeback part of red ginseng by naked eye and electron microscope. The specific surface area of normal, naeback and saengnaeback part appeared 3.02, 3.33 and 6.55 ㎡/g, respectively. From above results, we consider saengnaeback red ginseng is red ginseng in the intermediate process which normal red ginseng changes to naeback red ginseng.

Purpose: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. Materials and Methods: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as "mandibular canal", "alveolar canal", "inferior alveolar nerve canal", "inferior dental canal", "inferior mandibular canal" and "displacement". Results: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. Conclusion: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.

In lower abdominal flap representing transverse rectus abdominis musculocutaneous (TRAM) flap or deep inferior epigastric perforator (DIEP) flap, superficial inferior epigastric vein (SIEV) exists as superficial and independent venous system from deep system. The superficial venous drainage is dominant despite a dominant deep arterial supply in anterior abdominal wall. As TRAM or DIEP flaps began to be widely used for breast reconstruction, venous congestion issue has been arisen. Many clinical series in regard to venous congestion despite patent microvascular anastomosis site were reported. Venous congestion could be divided in two conditions by the area of venous congestion and each condition is from different anatomical causes. First, if venous congestion was shown in whole flap, it is due to the connection between SIEV and vena comitantes of DIEP. Second, if venous congestion is limited in above midline (Hartrampf zone II), it is due to problem in venous midline crossover. In this article, the authors reviewed the role of SIEV in lower abdominal flap based on the various anatomic and clinical studies. The contents are mainly categorized into four main issues; basic anatomy of SIEV, the two cause of venous congestion, connection between SIEV and vena comitantes of DIEP, and midline crossover of SIEV.

An enlarged inferior turbinate is a predisposing factor for difficult nasotracheal intubation. We describe a case of successful nasotracheal intubation by induced outfracture of the inferior turbinate during maxillofacial surgery, and discuss the importance of adequate airway evaluation and anesthetic management for successful nasal intubation.

We report a case of a 45-year-old woman with Budd-Chiari syndrome caused by the obstruction of the inferior vena cava just below the diaphragm. Transatrial dilatation or membranotomy was not possible due to the severe fibrotic obliteration of the inferior vena cava. Instead, cavoatrial bypass with a Dacron graft[20 mm-Vascutek] was performed under the median sternotomy and median abdominal incision.The postoperative course was uneventful and generalized symptoms were much improved. During the following period[6 month] the graft patency was maintained with no recurrence of symptoms.

Peripheral T-cell lymphoma, which characterized by progressive ulceration and necrosis of the upper aerodigestive tract or midline facial structures, is rare disease in the otolaryngologic field. We recently experienced a case, revealed histopathologically peripheral T-cell lymphoma, involving inferior turbinate without any evidence of involving other organs. In this paper, we report two cases of peripheral T-cell lymphoma who was treated chemotherapy and concurrent radiation therapy.
