[Osteomyelitis of the turbinates and its significance in chronic sinusitis].

We described the treatment of hyperplasia of the turbinate by sub-mucous resection of the inferior turbinate in 1981. The conchal bones removed were examined, and a histological study is now presented. In most cases we found a nonbacterial inflammation of the bone marrow of the inferior turbinate. The bearing of this and other changes in the bone marrow on the increase in size of the bone causing reduced ventilation of the nose and the paranasal sinuses, leading to sinusitis are discussed.

Chronic sinusitis in severe asthma is related to sputum eosinophilia.

BACKGROUND: Chronic rhinosinusitis and asthma are conditions that frequently coexist, particularly in severe asthma. The precise mechanism of the relationship between upper and lower airway inflammation is still a matter of debate. We hypothesized that the extent of inflammation in the nasal mucosa is related to lung function and inflammation in the bronchial mucosa in patients with severe asthma. OBJECTIVE: We sought to investigate the relationship between sinonasal inflammation as assessed on computed tomography (CT) scanning, lung function, sputum eosinophilia, and nitric oxide (NO) in exhaled air in patients with severe asthma. METHODS: Eighty-nine nonsmoking outpatients with severe asthma (29 men and 60 women; mean age 45 years; age range, 18-74 years) were included in this study. CT scans were scored (0-30) by a blinded investigator using a validated method. Lung function, NO in exhaled air, and sputum eosinophils were measured by using standard procedures. RESULTS: CT scans showed abnormalities in 84% of patients. Extensive sinus disease (score 12-30) was found in 24% of patients. There was a significant positive correlation between CT scores and eosinophils in peripheral blood (R(s) = 0.46) and induced sputum (R(s) = 0.40) and level of exhaled NO (R(s) = 0.45, P <.01). CT scores were also positively related to functional residual capacity and inversely related to diffusion capacity, particularly in patients with adult-onset asthma (R(s) = 0.47 and R(s) = -0.53, respectively). CONCLUSIONS: The results of this study show a direct relationship between sinonasal mucosa thickness and bronchial inflammation in severe asthma, particularly in patients with adult-onset disease. Whether sinus disease directly affects the intensity of bronchial inflammation is still an unanswered question.
