Abstract
PURPOSE: The non-invasive diagnosis of acute rhinosinusitis (ARS) remains an unresolved problem of modern otolaryngology. Analog diaphanoscopy of reduced transillumination (shading) could be enhanced by a digital image processing of the maxillary sinuses. By this means, the limited ergonomics of this safe and low-cost method can be overcome, and merits renewed the investigation. Here, we compared the diagnostic sensitivity and specificity of digital diaphanoscopy and computed tomography (CT) in detecting shading in the maxillary sinus. MATERIALS AND METHODS: We examined 103 adults using both digital diaphanoscopy of the maxillary sinus and native-phase cranial CT. We developed a scoring system for investigation of shading in the maxillary sinus using diaphanoscopy and compared the sensitivity and specificity with that of CT. Also, we documented a follow-up of acute rhinosinusitis. RESULTS: In diagnosing shading in the maxillary sinus, digital diaphanoscopy had a sensitivity of 86% and a specificity of 88%. Digital diaphanoscopy can be used not only in the screening of ARS but also for documentation of its course. CONCLUSION: This study supports the role of modern digital diaphanoscopy in the diagnosis of shading in the maxillary sinus, especially in patients with ARS when CT imaging is not recommended. The ergonomics of analog diaphanoscopy could be significantly improved for physicians and patients by the implementation of modern hardware and software components. Further development of the technique and the use of several discrete wavelengths will improve this method's sensitivity and specificity.
