Chronic rhinosinusitis is one of the most common inflammatory diseases with a significant impact on the affected patients. Orbital complications, one of the emergent complications of chronic rhinosinusitis, can be occurred in frontal sinusitis. For early diagnosis and therapy of orbital complications, proper evaluation is essential to prevent loss of vision.Recently, the authors diagnose and treat completely a 60-year-old man with isolated unilateral superior branch palsy of the oculomotor nerve caused by frontal sinusitis. Four days after draining the frontal sinusitis, the patient recovered fully from superior branch palsy of the oculomotor nerve. Frontal sinusitis can cause isolated superior branch palsy of the oculomotor nerve in patients with a history of facial trauma.
Background and Objectives: There are several diagnostic and therapeutic modalities for chronic rhinosinusitis (CRS), but specific guidelines have not been developed for Koreans. This study sought to evaluate and report CRS practice patterns of members of the Korean Rhinologic Society.Materials and Method: An anonymous survey including 32 items was conducted from August to September 2015. The survey items were categorized into three parts: general information, diagnosis and treatment of CRS, and endoscopic sinus surgery.Results: A total of 267 members participated in this survey. Almost half of the respondents (41.9%) were in their 40s and 42.7% had 10-20 years of experience. A total of 61.8% were private practitioners, while the rest worked in hospitals (38.2%). The prevalence rate of acute rhinosinusitis was higher in private clinics compared to hospitals (p<0.001). Intranasal steroids and saline irrigation were more commonly prescribed among hospital doctors compared to private practitioners (p<0.001). Amoxicillin/clavulanic acid was the drug of choice for adult and pediatric CRS patients among private practitioners. However, hospital doctors preferred macrolides for adult CRS patients and third-generation cephalosporins for pediatric CRS patients. Most private clinics performed surgery under local anesthesia (90.8%), while those in a hospital setting preferred general anesthesia (78.4%). Revision surgery rates were higher in hospitals compared to private clinics (p<0.001).Conclusion: There were significant variations in CRS practice patterns between private clinics and hospitals. For effective and standardized diagnosis and management of CRS, appropriate local guidelines are needed.
ObjectivesTo evaluate the surgical outcomes of endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stenting in patients with distal or common canalicular obstructions.MethodsThe medical records of 29 patients (31 eyes) from January 2001 to December 2009 who underwent endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone tube insertion for the treatment of distal or common canalicular obstructions were retrospectively reviewed. The level of obstruction was confirmed by intraoperative probing. The outcome of the surgery was categorized as a complete success, partial success, or failure according to the functional and anatomic patency.ResultsThe average age of the patients was 52 years. The duration of silicone intubation ranged from 4 to 11 months with an average of 5.7±1.6 months. The follow-up period after stent removal ranged from 4 to 15 months with an average of 8.2±3.3 months. Complete success was achieved in 25 out of 31 eyes (80.6%), partial success in 4 out of 31 eyes (12.9%), and failure in 2 out of 31 eyes (6.5%).ConclusionEndoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stent intubation may be safe and considered as an initial treatment of patients with distal or common canalicular obstructions.
The effect of several parameters to minimize the braking response time has been investigated in this study. The experimental rigs were developed and the results of the experement compared with those of simulation obtained from the net work fluid flow system analysis code (FLOWMASTER). The braking response time and pressure loss were observed at separated braking port and found out that the response time can be reduced by considering the pipe length and environmental thermal conditions. The correlation equation was also presented to predict the pressure loss at various tank pressure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
