Unilateral nasal obstruction
Introduction
Introduction When there are ectopic teeth, extra teeth or reverse teeth in the nasal cavity, it is called nasal cavity. Symptoms are unilateral nasal obstruction, bloody purulent sputum between the pus and odor. There are ectopic teeth, extra teeth or reverse teeth in the nasal cavity. The openings of the sinuses are all located in a narrow, concealed ditch or fossa that cannot be directly viewed, which makes it difficult to judge and diagnose the disease. Endoscopy of the nose and sinuses, in addition to the ethmoid sinus, all other sinuses can be used to look directly at the sinus. The source of purulent secretions can be clarified, and the pupil location of cerebrospinal fluid rhinorrhea can also be diagnosed. For the main cause.

1, nasal examination
Pay attention to nasal mucosa color, turbinate, nasal passages, olfactory grooves, etc. In acute rhinitis, the membrane is acutely congested with edema, and the nasal passages have clear watery, mucous, and purulent secretions. Chronic rhinitis, mucous membrane dark red, swollen, sticky in the nasal passages. Allergic rhinitis, vasomotor rhinitis, nasal mucosa pale purple gray. Acute and chronic sinusitis, pus in the middle nasal passage and olfactory sulcus.
2, nasal and sinus endoscopy
Routine examination of the nasal or posterior nasal cavity of the nasal cavity has a limited range of examinations for the nasal cavity. Many important parts of the nose, such as the opening of each sinus, are located in a narrow, concealed ditch or fossa that cannot be directly viewed, which makes it difficult to judge and diagnose the disease. Endoscopy of the nose and sinuses, in addition to the ethmoid sinus, all other sinuses can be used to look directly at the sinus. The source of purulent secretions can be clarified, and the pupil location of cerebrospinal fluid rhinorrhea can also be diagnosed.
3, CT examination
CT can examine both the sinus and the brain, so it is an important method for the diagnosis of fatal sinus diseases. To identify early benign and malignant lesions, CT can be used to distinguish vascular, fat, necrotic, hemorrhagic, cystic or calcified lesions, which is conducive to the analysis of the cause.
Diagnosis
Differential diagnosis
Differential diagnosis of unilateral nasal obstruction:
1. There is nasal congestion in the lower nasal cavity when lying on the side: alternating nasal congestion: the nasal cavity on the lower side is often blocked and aggravated when lying on the side. After lying on the other side, there was no nasal congestion or a nasal congestion on the upper side. After turning to the lower side, a nasal congestion or nasal congestion was aggravated. The nasal nasal congestion just below the lower side was alleviated. In addition, the sense of smell can be reduced to varying degrees, and the speech is an occlusive nasal sound. Because the nasal sputum flows through the nasal vestibule and upper lip for a long time, it can cause dermatitis or eczema, which is more common in children. The sinus can flow backward into the pharynx, causing symptoms such as cough and phlegm. This is one of the clinical symptoms of patients with chronic simple rhinitis.
2, deep nasal congestion: the main symptoms of nasal foreign body disease is deep nasal congestion, purulent nasal discharge. The nasal foreign body is a substance inside and outside the nasal cavity. Nasal foreign substances can be divided into the following three types: 1 non-biological categories: such as sugar paper, plastic plastic toys, buttons, necklace beads, glass beads, stones, soil and so on. 2 Plants: such as beans, peanuts, fruit cores, etc. 3 Animals: such as insects, mites, mites, leeches and so on.
3, paroxysmal nasal congestion: paroxysmal nasal congestion is a nasal congestion caused by rhinitis, showing paroxysmal.
4. Nasal obstruction during inhalation: The clinical manifestations of nasal valve stenosis are mainly nasal obstruction during inhalation, both unilateral and bilateral.
