Comparative Study
Clinical utility of intraoperative volume computed tomography scanner for endoscopic sinonasal and skull base procedures.
Intraoperative surgical navigation has become widely accepted as an important tool for improvement of surgical outcomes and reduction of complication in endoscopic sinus surgery (ESS). The purpose of this study was to assess the clinical utility of intraoperative volume computed tomography (CT) scanning in endoscopic sinonasal and skull base procedures. ⋯ Intraoperative volume CT scanning was successfully performed in 25 patients undergoing ESS. Because additional surgical intervention was performed in 24% of cases, this technology may have an important role in endoscopic sinonasal and skull base procedures.

Comparative Study
Does nasal irrigation enter paranasal sinuses in chronic rhinosinusitis?
Nasal irrigation is widely used in treating sinonasal diseases. Not only does it remove static secretions and promote mucociliary clearance, but, in chronic rhinosinusitis, nasal flush is also a potential route for topical drug administration into paranasal sinuses. A clinical study was conducted to investigate how well nasal irrigation could reach paranasal sinuses with the ostiomeatal units blocked in chronic rhinosinusitis. This study was performed to (1) assess the ability of a nasal douche and spray to deliver a solution into the paranasal sinuses in chronic rhinosinusitis and (2) compare the performance of the two techniques. ⋯ Nasal douche and spray is not effective in delivering a nasal irrigation solution into paranasal sinuses in chronic rhinosinusitis.
