The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

This is a clinical and retrospective study of 36 patients received the autogenous particulated cancellous bone grafts from anterior iliac and proximal tibial metaphysis and we compared the clinical postoperative complications in operation sites and donor site morbidity. The results of this study indicate that, in all our patients, the proximal tibia provided an adquate volume of cancellous bone and there were no special contraindications, in choosing and using the proximal tibia as a donor site in most oral and maxillofacial cancellous bone graft surgeries. Furthermore, the proximal tibial metaphysis would appear a more easily obtainable cancellous bone source and offer a superior clinical results than anterior iliac crest in donor site morbidity.

Korean women are now living almost 1/3 of their life after menopause. Sex-steroid hormone deficiency adversely affect various fields of physical & mental activity and quality of life during this period. Therefore, replacement of deficient hormone is thought to be natural therapeutic modality. Postmenopausal syndrome is recently redefined as an endocrinopathy with both short-and long-term sequelae, as a result of cessation of ovarian function. Hormone replacement therapy taken at or near time of menopause alleviates shot-term acute menopausal symptoms such as vasomotor disturbances and psychological problems. HRT also beneficially affects some of intermediate symptoms such as urogenital atrophy and cutaneous problems. The major benefits of long-term use were reductions in risk of long-term sequelae, that is, total fracture by 50-60%, cardiovascular disease by 50% and cerebrovascular disease by 30-40%, respectively. In addition, HRT may also positively influence Alzheimer's disease, reduce the colorectal cancer risk and increase longevity of the life. In conclusion, all postmenopausal women should consider preventive HRT when there are no contraindications.

Inverted maxillary incisor is that maxillary incisor rotates to the counterclockwise direction. The incisal margin and root apex of the impacted incisor is palpated at the mucobuccal fold near the labial frenum and on the palate among the rugae, respectively. Orthodontists confront ectopically erupting teeth in various locations. In the past, extraction of impacted teeth that deviated from their normal course of eruption had been performed indiscriminately. But, if it has not any clearcut contraindications, effeort should be made to achieve optimal esthetic results by conservative means, combining the skills of oral surgeon and orthodontist. The present report provides an illustration of satisfactory correction of a inverted maxillary incisor with surgical intervention and many springs that correct the tooth axis. This technique provides the clinician with an additional means to avoid unnecessary extraction of inverted teeth in certain cases.

Biopsy is a critical method for disease diagnosis and treatment planning. It can be applied from simple inflammatory lesions to malignant tumors. But many general dental practitioners are unfamiliar with the basic knowledge and skills required for biopsy. Moreover, biopsy indications and contraindications for certain diseases may differ depending on the type of dental practice environment and the specialty of the dentist. Biopsy education can increase the choices a dentist has during disease diagnosis. Here we will discuss details on biopsy needed to the general dentist.

Objectives : This research aimed to verify the validities of contraindicated acupoints in acupuncture or moxibustion treatments in Taipingshenghuifang and Tongrenzhenjiujing. Methods : We investigated contraindicated acupoints when performing needling or moxibustion in Taipingshenghuifang and Tongrenzhenjiujing, then verified them in various literatures and today's medical knowledge. Results : In Taipingshenghuifang and Tongrenzhenjiujing, 15 acupoints were described to need a careful approach in acupuncture treatment, and 24 acupoints were described so in moxibustion treatment in common. And additionally GB1 was described to need a careful moxibustion treatment in Taipingshenghuifang. Most of the descriptions for the contradindicated acupoints can be explained based on medical knowledge. Conclusions : The contraindicated acupoints in acupuncture or moxibustion treatments in Taipingshenghuifang and Tongrenzhenjiujing seem to have been classified based on the experience of the doctors at that time. Therefore they may be referred to for safe acupuncture or moxibustion treatments at these points.

High-flow nasal cannula (HFNC) is a relatively safe and effective noninvasive ventilation method that was recently accepted as a treatment option for acute respiratory support before endotracheal intubation or invasive ventilation. The action mechanism of HFNC includes a decrease in nasopharyngeal resistance, washout of dead space, reduction in inflow of ambient air, and an increase in airway pressure. In preterm infants, HFNC can be used to prevent reintubation and initial noninvasive respiratory support after birth. In children, flow level adjustments are crucial considering their maximal efficacy and complications. Randomized controlled studies suggest that HFNC can be used in cases of moderate to severe bronchiolitis upon initial low-flow oxygen failure. HFNC can also reduce intubation and mechanical ventilation in children with respiratory failure. Several observational studies have shown that HFNC can be beneficial in acute asthma and other respiratory distress. Multicenter randomized studies are warranted to determine the feasibility and adherence of HFNC and continuous positive airway pressure in pediatric intensive care units. The development of clinical guidelines for HFNC, including flow settings, indications, and contraindications, device management, efficacy identification, and safety issues are needed, particularly in children.

A cuttlefish bone is not a bone, but the internal shell of the Cuttlefish/ sepia officinalis, a small, squid-like cephalopod of phylum molusca, an animals of the order Sepiida. Cuttlefish bone comprises up to 90 percent of its content of calcium carbonate with the abundance of different bioinorganic elements such as magnesium, strontium, iron, even trace amounts of copper, zinc, aragonite and ${\beta}$-chitin which makes it extremely valuable and worthwhile to be used for biomedical research. Unani system of medicine has been using cuttlefish bone under the name of 'kafe dariya' for the treatment various disorders and ailments since centuries. Unani scholars were well aware of the valuable medical and cosmetologically aspect of cuttlefish bone. However, the drug has been forgotten for its beneficial effect and went deep away from the scientific researches. The purpose of the present review is to highlight and revive the data on cuttlefish and cuttlefish bone for its morphology, composition, types, pharmacological actions, temperament, therapeutic dosage, contraindications, correctives, alternatives and therapeutic uses with special reference of Unani medicine to attain its the beneficial features in biomedical sciences.
