Obstructive sleep apnea (OSA) in children is a frequent disease for which optimal diagnostic methods are still being defined. Treatment of OSA in children should include providing space, improving craniofacial growth, resolving all symptoms, and preventing the development of the disease in the adult years. Adenotonsillectomy (T&A) has been the treatment of choice and thought to solve young patient's OSA problem, which is not the case for most adults. Recent reports showed success rates that vary from 27.2% to 82.9%. Children snoring regularly generally have a narrow maxilla compared to children who do not snore. The impairment of nasal breathing with increased nasal resistance has a well-documented negative impact on early childhood maxilla-mandibular development, making the upper airway smaller and might lead to adult OSA. Surgery in young children should be performed as early as possible to prevent the resulting morphologic changes and neurobehavioral, cardiovascular, endocrine, and metabolic complications. Close postoperative follow-up to monitor for residual disease is equally important. As the proportion of obese children has been increasing recently, parents should be informed about the weight gain after T&A. Multidisciplinary evaluation of the anatomic abnormalities in children with OSA leads to better overall treatment outcome.

Background and Objectives : Adenotonsillar hypertrophy is the most common disorder in pediatric otolaryngology, which should be suspected as a possible cause of obstructive sleep apnea syndrome (OSAS). In the past, most of the adenotonsillectomy were performed because of recurrent infection, but now OSAS is the most common indication in many centers. Materials and Method : A review of 1,945 adenotonsillectomy performed between 1990 and 1998 is presented. We classified into two categories of indication for adenotonsillectomy and analyzed changing trends of indication for adenotonsillectomy. Results : Although recurrent infection remains the predominant indication for surgery, there has been a rise in OSAS as a significant indication from 13.67% in 1990 to 24.26% in 1998. Conclusion : An increase has occurred in the percentage of adenotonsillectomy performed for OSAS due to adenotonsillar hypertrophy. This trend promises to continue as physicians become increasingly aware of the prevalence and seriousness of adenotonsillar hypertrophy as a cause of sleep apnea.

Lateral pharyngoplasty is a surgical option for treatment of obstructive sleep apnea (OSA). Here, we present a case involving a 40-year-old healthy man who underwent surgery, including lateral pharyngoplasty and robotic tongue base resection, for OSA. There were no intraoperative or immediate postoperative complications. However, on postoperative day 3, the patient presented with swelling in the temporal and buccal areas and was diagnosed with subcutaneous emphysema, later confirmed by computed tomography. The patient was carefully monitored under conservative care and discharged without complications. Although subcutaneous emphysema following tonsillectomy is a rare complication and usually resolves with conservative management, in certain cases, it might require surgical intervention. Lateral pharyngoplasty involves tonsillectomy and additional incision along the tonsillar fossa, which makes it susceptible to pharyngeal wall defects and, consequently, subcutaneous emphysema. Additionally, lateral pharyngoplasty and robotic tongue base resection cause pain and might thus contribute to the increase in intrapharyngeal pressure, which might aggravate subcutaneous emphysema. Lateral pharyngoplasty should be performed with meticulous dissection of the superior pharyngeal constrictor muscle. Healthcare providers should be aware of these complications and, upon suspicion of the same, place the patient under close observation to prevent life-threatening situations.

The aim of this study is to determine if intra-bursal morphine and Bupivacaine mixed infusion provided useful analgesia after subacromial arthroscopic operation. At the end of the subacromial arthroscopy, continuous intra-bursal infusion catheter was inserted. In a double-blind randomized trial, Sixty patients were allocated to one of two groups: placebo group(n=30) received continuous saline infusion. Study group received mixed 5㎖ of 0.5% Bupivacaine, 2㎎ of morphine and 0.05㎖ of 1/1000 epinephrine as bolus and mixed solution of 40㎖ of 0.5% Bupivacaine and 8㎎ of morphine as maintenance dose with continuous infusion pump(0.5㎖ hourly). In the placebo group, two patients were discontinued due to leakage and catheter coming out each. Intensity of pain was evaluated preoperatively and postoperatively for 3 days by 10 graded visual analogue scale. Night pain, pain on motion, sleep disturbance, lying on painful shoulder and amounts of intramuscular pain killer were recorded. Analgesic effect for pain was cleared at 1st and 2nd postoperative day and there was less sleep disturbance for 3 days postoperatively in study group. There was no difference in pain on motion postoperatively. In study group, less pain killers were used in the first 48 hours postoperatively. The continuous intra-bursal infusion decreased perception of pain at resting stage and reduced supplemental analgesic requirement for 2 days postoperatively.

Purpose: To evaluate the upper airway dimensions of obstructive sleep apnea (OSA) and control subjects using a cone-beam computed tomography (CBCT) unit commonly applied in clinical practice in order to assess airway dimensions in the same fashion as that routinely employed in a clinical setting. Materials and Methods: This was a retrospective analysis utilizing existing CBCT scans to evaluate the dimensions of the upper airway in OSA and control subjects. The CBCT data of sixteen OSA and sixteen control subjects were compared. The average area, average volume, total volume, and total length of the upper airway were computed. Width and anterior-posterior (AP) measurements were obtained on the smallest axial slice. Results: OSA subjects had a significantly smaller average airway area, average airway volume, total airway volume, and mean airway width. OSA subjects had a significantly larger airway length measurement. The mean A-P distance was not significantly different between groups. Conclusion: OSA subjects have a smaller upper airway compared to controls with the exception of airway length. The lack of a significant difference in the mean A-P distance may indicate that patient position during imaging (upright vs. supine) can affect this measurement. Comparison of this study with a future prospective study design will allow for validation of these results.

Objectives: The present mini review aimed to summarize the existing knowledge regarding the beneficial and adverse effects of raloxifene in menopausal women. Methods: This study is a review of relevant publications about the effects of raloxifene on sleep disorder, depression, venous thromboembolism, the plasma concentration of lipoprotein, breast cancer, and cognitive function among menopausal women. Results: Raloxifene showed no significant effect on depression and sleep disorder. Verbal memory improved with administration of 60 mg/day of raloxifene while a mild cognitive impairment risk reduction by 33% was observed with administration of 120 mg/day of raloxifene. Raloxifene was associated with a 50% decrease in the need for prolapse surgery. The result of a meta-analysis showed a significant decline in the plasma concentration of lipoprotein in the raloxifene group compared to placebo (standardized mean difference, -0.43; 10 trials). A network meta-analysis showed that raloxifene significantly decreased the risk of breast cancer (relative risk, 0.572; 95% confidence interval, 0.327-0.881; P = 0.01). In terms of adverse effects of raloxifene, the odds ratio (OR) was observed to be 1.54 (P = 0.006), indicating 54% increase in the risk of deep vein thrombosis (DVT) while the OR for pulmonary embolism (PE) was 1.05, suggesting a 91% increase in the risk of PE alone (P = 0.03). Conclusions: Raloxifene had no significant effect on depression and sleep disorder but decreased the concentration of lipoprotein. Raloxifene administration was associated with an increased risk of DVT and PE and a decreased risk of breast cancer and pelvic organ prolapse in postmenopausal women.

Background: The posterior movement of mandible was known as the main cause of the changes in the pharyngeal airway space (PAS) and the postoperative obstructive sleep apnea (OSA). The purpose of this study was to know the changes of PAS and position of hyoid bone. Methods: Lateral cephalographies of 13 patients who had undergone sagittal split ramus osteotomy (SSRO) setback surgery were taken preoperatively (T1), postoperatively within 2 months (T2), and follow-up after 6 months or more (T3). On the basis of F-H plane, diameters of nasopharynx, oropharynx, and hypopharynx were measured. The movements of the soft palate, tongue, and hyoid bone were also measured. Results: The amount of mandible setback was $7.5{\pm}3.8mm$. In the measurements of PAS, there was a statistically significant decrease of $2.8{\pm}2.5mm$ in nasopharynx (P < 0.01), and $1.7{\pm}2.4mm$ in oropharynx (P < 0.01) were observed after surgery. The hypopharynx decreased $1.0{\pm}2.1mm$ after surgery and continuously decreased $1.0{\pm}2.8mm$ at follow-up. The changes in hyoid bone position showed the posterior movement only after surgery and posteroinferior movement at follow-up. Conclusions: The PAS such as nasopharynx, oropharynx, and hypopharynx showed relatively high correlation with the amount of mandibular setback. The change of resistance in upper airway may be important for the prevention of OSA after mandibular setback surgery.

Purpose: The purpose of this study was to evaluate preoperative nutritional status in elderly patients with orthopedic surgery and identify related factors for malnutrition risk. Methods: This study enrolled 337 patient's medical record who underwent orthopedic surgery in hospital between January and December 2015. Data was collected retrospectively. Nutritional status was evaluated by using the Nutritional Risk Screening 2002. Multivariable logistic regression analysis was used to identify independent related factors for malnutrition risk. Results: Malnutrition risk developed in 58 patients (17.2%). Logistic regression analysis identified low physical activity, visual impairment, depression, sleep disorder, low serum calcium level, and low serum albumin level as related factors. Conclusion: Orthopedic surgery in elderly patients was associated with high risk of preoperative malnutrition. The results of this study suggest that evaluating the nutritional status and related factors should be done with preoperative status of elderly patients. At the same time, interventions for nutritional care should be adjusted to meet the nutritional needs of individuals and decrease the risk of malnutrition.
