“…Overall prevalence of the present study is comparable with the results of most CT studies: 42.5 [5], 41.7 [6]. and 39% [7], One study [8] mentions quite different results: overall prevalence of 27%, maxillary involvement of only 8% with no polyps seen on any scan. For this latter study, it has to be noted that the maxillary sinuses were only seen in 38 out of 100 patients.…”

“…However, most CT studies in asymp tomatic populations show the ethmoidal rather than the maxillary sinuses as the first site of involvement: 28.4 and 24.8%, respectively [5], 28 and 18% [7], 21 and 8% [8], Only one CT study confirms the highest prevalence rate at the level of the maxillary rather than the anterior ethmoi dal sinuses: 27.8 and 19.4% [6]. Perhaps some of the more minor maxillary mucosal changes remain undetected on CT scans.…”

Relatively little is known about the prevalence of sinusitis in a general population. Patients with suspected intracranial neurological disease can be considered as representative of the general population. On magnetic resonance imaging nearly 60% of the sinuses were affected. If the most common lesion (a maxillary polyp or cyst) was excluded, still 40% of the sinuses were affected. Above all the maxillary sinuses are involved with 40% abnormal images followed by the anterior ethmoidal sinuses with 14%. The other sinuses are less likely to be affected with 2.5% of the sphenoidal, 2% of the frontal and 1.5% of the posterior ethmoidal sinuses.

“…The finding that otolaryngologists diagnosed sinus disease at a lower rate than the CT scan, alone, supports previous research showing that not all abnormalities found on CT scans indicate rhinosinusitis [10][11][12] . This finding supports the need for expert clinical evaluation.…”

Background/Aims: To determine if patients with benign paroxysmal positional vertigo (BPPV) have a higher frequency of rhinosinusitis than people with normal vestibular function. Methods: The subjects were 52 patients with BPPV and 46 normal people. Every subject had a sinus CT scan, a blood draw for IgE and a rhinologic examination by an otolaryngologist. Results: The frequency of rhinosinusitis based on physician diagnosis was 49% and based on CT scan findings 59%. This difference approached significance (p = 0.08). The observed frequency of rhinosinusitis was higher than predicted by survey data about the southern US region. The data trended toward higher prevalence of rhinosinusitis (by physician diagnosis) in the BPPV patients versus controls (58 vs. 39%, p = 0.06). Conclusion: BPPV patients have a higher frequency of sinus disease compared to people with normal vestibular systems, perhaps due to age differences, but physiologic factors may also be involved. The higher frequency of rhinosinusitis in this geographical area than reported rates based on survey data raises concerns about the usefulness of questionnaire data for estimating population prevalence.

“…Correlation of plain films with CT scans to evaluate mucosal thickening or opacification occurs in only 40% [10]. Similarly, negative plain films correlate with CT scanning in only about 10% [11]. Because the sensitivity and specificity occurs in such low percentages, plain films are not recommended for routine use in evaluating chronic rhinosinusitis.…”

Endoscopic and imaging techniques in the diagnosis of chronic rhinosinusitis

The definition of chronic rhinosinusitis globally applies to any patient who has nasal and/or sinus inflammatory disease for a period of more than 3 months, provided the patient has particular signs and symptoms. However, to treat chronic rhinosinusitis appropriately, specific etiologies must be diagnostically ruled in or out. Chronic rhinosinusitis can be complex, because there are several factors involved in its causation. Endoscopy and imaging can play a role in helping to lead to a more specific diagnosis, allowing more targeted treatment.
