[Significance of local pain syndrome in patients with frontitis]
Abstract:
The diagnostic value of local pain symptom as a key sign of frontitis is currently regarded as rather low. It occurred only in 69 (14%) of the 487 patients with this disease examined in the present study. Patients presenting with ambiguous symptoms of uncomplicated unilateral frontitis were studied by rheofrontography using coefficient of asymmetry as a diagnostic criterion (its value in excess of 24% indicates the presence of exudate in the sinus cavity. The electron microscopic study demonstrated the presence of morphologically different cells in frontal sinus mucosa of patients with uncomplicated frontitis with and without local pain symptom. These findings are in excellent agreement with the data on the relationship between immunological and neurogenic components of the inflammatory reaction in patients with diseases of the upper respiratory tract.
