Foreign bodies lodged in the intraconal space of the orbit pose a surgical challenge due to its deep location behind the globe. Image-guided endoscopic transnasal surgery facilitates the localization of the metallic foreign bodies and enables its safe removal with minimal surrounding tissue damage and optic nerve injury.
Descending necrotizing mediastinitis (DNM) is a rapidly progressive disease from the spread of cervical infection. Transcervical and transthoracic drainage was the recognized traditional surgical approach to achieve adequate clearance of infection. Non-invasive vacuum-assisted dressing is a new technique where applied negative pressure can help remove infective fluid and to promote wound healing. A 60-year-old man presented with odynophagia, fever and anterior neck swelling for 2 weeks. He was diagnosed to have anterior neck abscess and underwent surgical drainage. However, it did not respond well, but progressed to involve superior and inferior mediastinum. Vacuum-assisted dressing was applied for total of 2 weeks and the patient recovered without going through usual traditional transthoracic drainage. Vacuum drainage is a simple, safe and non-invasive method of managing DNM, in well selected group with small abscess cavity without airway obstruction and septicemia. This potential technique can lead to paradigm shift in treating life-threatening DNM.
Objective To objectively compare the nasal decongestion potency of lidocaine/phenylephrine when delivered with a nasal nebulizer and a nasal spray before a rigid nasoendoscopic examination. Study Design Open-label randomized controlled trial. Setting Multicenter study. Methods This prospective clinical trial involved 106 participants with untreated chronic rhinitis. Fifty-three participants had 400 μL of lidocaine/phenylephrine administered into the right nostril with a nasal nebulizer, while the remaining 53 participants had 400 μL administered with a nasal spray. The control was the left nostril. Nasal resistance at 150-Pa fixed pressure was evaluated with an active anterior rhinomanometry at 5, 10, 15, and 30 minutes postintervention. Pain score was assessed subjectively by applying pressure to the inferior turbinate 30 minutes after intervention. Results There was an overall reduction in nasal resistance of the right nostril when lidocaine/phenylephrine was administered with the nasal nebulizer in comparison with the nasal spray. However, a statistically significant difference in nasal resistance was seen only at 5 minutes ( P = .047), 15 minutes ( P = .016), and 30 minutes ( P = .036). The examining endoscopist further supported the degree of nasal decongestion via subjective assessment of the nasal cavity ( P = .001). Pain scores obtained after the intervention showed a significant decrease in pain threshold when the nasal nebulizer was used instead of the nasal spray ( P = .040). Conclusions This study suggests that the delivery of lidocaine/phenylephrine to the nasal cavity by the nasal nebulizer provides better decongestive and analgesic potency as compared with the delivery by nasal sprays.
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.
