The nasal cavity located on the lower side often becomes more obstructed when lying on the side. After transferring to the other side, the nasal cavity that was not congested or was less congested on the upper side, became congested or more congested after transferring to the lower side. The nasal cavity that was located on the lower side just now has less nasal congestion. In addition, the sense of smell may be diminished to different degrees, and the speech is occlusive nasal sound. Due to the long-term flow of nasal mucus through the nasal vestibule and the upper lip, it can cause dermatitis or eczema, mostly seen in children. The nasal mucus may flow backward into the pharyngeal cavity, and symptoms such as cough and phlegm may appear. This is one of the clinical symptoms of patients with chronic simple rhinitis.
Clinically, for patients with nasal congestion located in the lower nasal cavity when lying on the side to be examined: I. Physical examination Taking a medical history gives us an initial impression and insight, and also guides us to have a concept of the nature of the disease.
Laboratory examination Laboratory examination must be based on the objective materials learned from the history and physical examination for generalization and analysis, from which several diagnostic possibilities are proposed, and then further consideration is given to those laboratory examinations to confirm the diagnosis. For example, ENT examination: the nasal mucosa is swollen, with smooth, moist surface and generally dark red. The turbinate mucosa is soft and elastic, and the probe can be depressed by light pressure, but the depression will recover quickly if the probe is removed, especially in the inferior turbinate. If 1~2% ephedrine solution is used for nasal mucosa contraction, the turbinates shrink rapidly. There is mucous or purulent secretion from the common nasal passage or inferior nasal passage.
