Nose picking

Introduction The nose is the gateway to the human respiratory tract. 1 There are abundant capillaries in the nasal cavity, secreting viscous liquid, warming cold air and moistening dry air. 2 The nose hair is criss-crossed, such as a protective barrier, which filters out dust and heavy impurities. The normal function of the nose is directly related to the health of the respiratory tract. The nasty but inevitable habit of picking up the nostrils, a quarter of the teenagers averaged 4 times a day. Scientists have tried to find out what its purpose is, but it is in vain. It has been suggested that the nostrils will strengthen the immune system. Poor nose habits often lead to atrophic rhinitis. Due to atrophy of the nasal mucosa and decreased secretion, the defensive ability of the nasal cavity is reduced or lost, resulting in a series of diseases of the respiratory system, such as chronic pharyngitis, chronic bronchitis, sinusitis, and even secondary lung infections.

Cause

(1) Primary: It is considered to be a partial manifestation of systemic diseases, which may be related to the lack of lipids and fat-soluble vitamins, or to nutritional disorders, trace element deficiency or imbalance, genetic factors, collagen diseases, etc. It may also be related to endocrine disorders, which are more common in young women and worsen during menstruation. In recent years, with the development of immunology, most patients with this disease have been found to have immune dysfunction, so some people believe that this disease may be an immune disease.

(2) Secondary: caused by local factors, such as traumatic or surgical resection of the nasal mucosa, or due to special infectious diseases such as tuberculosis, induration, leprosy, syphilis and so on. In the advanced stage of chronic hypertrophic rhinitis, or long-term purulent sputum stimulation of chronic suppurative sinusitis, excessive proliferation of fibrous connective tissue occurs, resulting in obstruction of blood circulation of the nasal mucosa and atrophy due to nutritional disorders. The nasal septum is extremely deflected, one side of the nasal cavity is wide, the stimulation of the enhanced airflow, or the long-term stimulation of dust or harmful gases can also cause disease. It has been suggested that the disease is caused by a special bacterial infection such as Rhizoctonia solani or diphtheria-like infection. It is believed that these bacteria are not true pathogens and are only secondary infections of atrophic rhinitis.

Early pathological mucosa showed only chronic inflammation changes, which in turn progressed to progressive atrophy. Mucosal and bone vessels gradually develop occlusive endarteritis and spongy venous plexus, connective tissue hyperplasia of the vessel wall, narrowing or occlusion of the lumen, poor blood circulation, leading to mucosal, glandular, periosteal and bone atrophy, fiber The pseudo-stratified ciliated columnar epithelium of the mucosa gradually transforms into a stratified squamous epithelium. Even pterygopalatine ganglia can also undergo fibrosis.

an examination

Nasopharyngeal MRI examination nasal endoscopy

1, nasal cavity, nasopharyngeal dryness, nasal congestion, headache, breathing stench, nose, loss of smell and so on.

2, the nasal cavity is wide, the mucous membrane is dry and atrophy, the turbinate is reduced, and there are a lot of suede or thick purulent secretions.

Diagnose based on:

1, a long history, more common in young women, or nasal trauma, and multiple history of nasal surgery.

2, have the above symptoms and signs.

Differential diagnosis

According to the characteristics of alternating and intermittent nasal congestion, combined with clinical examination, diagnosis is not difficult. The following diseases should be identified:

(1) hypertrophic rhinitis: persistent book stuffing is often heavier, not much nasal discharge, mucinous or purulent, generally have varying degrees of headache, dizziness and decreased sense of smell.

(2) allergic rhinitis: the degree of nasal congestion is different, more sudden appearance, nasal sputum is thin, the amount is more, often accompanied by nasal itching, sneezing frequently.

(3) atrophic rhinitis: the nasal cavity is wide, but due to a large amount of hoarding, can produce nasal congestion, nasal dryness, accompanied by nasal odor, the sense of smell is significantly reduced, often accompanied by more severe headache.
