What is the reason? We know that common nasal and sinus diseases can be divided into two broad categories. One is inflammatory diseases, including acute rhinitis, chronic sinusitis, nasal polyps and so on. They have a common feature, that is, most of them are bilateral nasal lesions.

When a person has a cold or rhinitis, the severity of symptoms on both sides of the nasal cavity may not be the same, but both sides must feel uncomfortable.

Another type of disease is unilateral nasal disease, clinically collectively referred to as unilateral nasal sinus disease. These diseases are mainly tumor diseases, but also include some special infections or tumor-like diseases.

So, unilateral nasal sinus disease, what are the warning signs?

Nasal congestion is one of the most common symptoms of nasal disease. Well-known chronic rhinitis, allergic rhinitis, sinusitis, nasal septum deviation, etc., can lead to bilateral nasal congestion. Bilateral nasal congestion may occur simultaneously or alternately.

Because the mucosal structure of both nasal cavities is the same, when bacteria or allergens enter the nasal cavity, both nasal mucosa will be irritated and cause symptoms. However, if it is unilateral nasal congestion, it means that the lesion occurs only on one side of the nasal cavity, so the cause is often not external stimulation such as bacteria or allergens, but endogenous factors that originate in the nasal cavity.

Therefore, unilateral nasal congestion suggests that we should consider the possibility of developing tumor-like diseases of the nasal cavity and sinuses. One of the first symptoms of common benign and malignant tumors of the nasal cavity and sinuses, such as inverted papilloma, squamous cell carcinoma, lymphoma, etc., is unilateral nasal congestion.

Nosebleed is one of the common nasal emergencies, which can occur in people of all ages, often in the elderly and children. Mild cases only show blood in the nose, severe cases can lead to hemorrhagic shock.

The etiology of epistaxis is complex, including not only local nasal factors, but also some systemic factors. In adults, epistaxis is often associated with cardiovascular disease, the use of non-steroidal anti-inflammatory drugs and alcohol abuse. In children, epistaxis is more common in nasal dryness, allergic reactions, foreign bodies in the nose, blood system diseases, kidney diseases and dietary problems.

It can be seen that nosebleed is an important warning signal of abnormalities in the body, and different manifestations of nosebleed suggest different health problems. For example, a small amount of blood in the nasal cavity or blood in the nose, bilateral alternately occurring or dominated by one side, bleeding once or twice a day or a few days apart, the amount of blood loss is small, through local pressure on the affected side of the nose or stuffing cotton balls and other methods of pressure hemostasis, more than ten minutes can control bleeding... Such a performance is generally bleeding in the front of the nasal cavity, patients are mostly children, often caused by dry nasal mucosa, often rub the nose or pick the nose.

If the nose bleeding in elderly patients often occurs at night, it is more related to unstable blood pressure control or long-term oral anticoagulant drugs.

If the adolescent male nosebleed, and the amount of blood loss is large, and the nasal cavity on the side of the bleeding is often nasal congestion, it is necessary to be vigilant about the occurrence of nasopharyngeal fibroangioma.

Most people have a headache, the doctor will first consider the problem in the head, but unilateral nasal sinus lesions cause headache and head and face pain is also more common.

Many diseases occur in the sinus, easy to involve or invade the skull base and orbit, causing headache symptoms, such as fungal sinusitis, sinus mucocele and so on.

Because there are rich sensory nerve endings in the sinus mucosa, under the stimulation of inflammation and tumors, people will appear head and face dull pain.

Different from headache caused by other causes, headache caused by unilateral nasal sinus disease has some characteristics. For example, the headache is often dominated by one side, the position is not fixed, can be located on one side of the face, forehead, temporal or occipital, pain to dull pain, swelling pain, dull pain, little jumping pain or acupuncture pain, the pain degree is not severe, but the duration is longer. Therefore, it is strongly recommended that patients with headache must not ignore the problem of nasal sinuses while ruling out intracranial diseases.

Olfactory function is one of the important functions of nasal cavity. If there is long-term anosmia on one or both sides, or even complete loss of smell, it is necessary to go to the hospital, because it may indicate the occurrence of nasal polyps or nasal tumors.

Anosmia is one of the four most common symptoms of chronic sinusitis and nasal polyps, and many patients cannot recover their sense of smell. Clinical observations have also found that the probability of olfactory function recovery is inversely proportional to the duration of olfactory disorders, that is, the longer the time of smell loss, the lower the likelihood of recovery.

Some patients have a normal sense of smell, but often can smell nasal or nasal odour, which is highly suggestive of odontogenic sinusitis. The maxillary sinus floor is closely related to alveolar bone and tooth root, and many root tip lesions will cause sinusitis, which is called odontogenic sinusitis.

Appears unilateral nasal discomfort, how to do

If it is bilateral nasal lesions caused by common rhinitis, the patient can play a role in prevention and treatment by ensuring rest time, improving the body's immunity, and developing good hygiene habits.

However, for unilateral nasal sinus lesions, these measures are obviously insufficient. Patients must go to a regular hospital as soon as possible, identify the cause through nasal endoscopy or imaging examination, and standardize treatment.
