With the increasing number of population, the competitiveness and pressure of people’s work are also rising gradually at present. I often meet some middle-aged and young patients in the clinic, and what surprises me is that people belonging to subhealth actually account for most of them, and many of them tell me that the night sleep cannot relieve the fatigue of the day. I often say to them that fatigue is divided into mental and physical fatigue. Heart tiredness depends on self-regulation, but body tiredness requires good sleep. Sleep disorders are also a hot topic of international medical concern, and March 21 is designated as International Sleep Day every year. Here I would like to introduce to my patients the common nasal diseases that affect sleep quality and their treatment. 1.What are the common nasal diseases that affect the quality of sleep? Rhinitis, sinusitis, nasal polyps, deviated septum and nasal neoplasia and adenoid hypertrophy in children are common nasal disorders. Under normal conditions, the human nasal cavity, except for the olfactory region, is covered by the mucosa of the respiratory region, which is a complex or pseudo-complex columnar ciliated epithelium, and the movement of the cilia is mainly from the front to the back towards the nasopharynx, like a broom, which plays the role of cleaning the nasal cavity of waste. The mucosa contains cells that produce secretions and normally keep the nasal cavity moist. When rhinitis and sinusitis occur, inflammatory lesions of the nasal mucosa lead to swelling of the mucosa, congestion, and massive secretion of mucus cells, resulting in enlargement of the inferior turbinates, clear snot, pus, or a headache with head swelling. The growth of nasal polyps can mechanically obstruct the nasal cavity, and the size of nasal polyps is directly related to the degree of nasal congestion. Nasal neoplasms often manifest as nasal congestion on one side and, in the case of malignancy, bleeding. Deviated nasal septum is a very common phenomenon, and deviated hypertrophy can cause nasal congestion on one side in obvious cases. Nasal congestion, runny nose, sneezing or nasal reflux can interfere with breathing and at night with normal sleep, leading to snoring and open-mouth breathing. In particular, it is important to mention that the incidence of adenoid hypertrophy in children is on the rise and is associated with colds, allergies and atmospheric pollution. The enlarged adenoids block the posterior nostrils, leading to sleep snoring. In severe cases, children will toss and turn, open-mouth breathing and breath-holding, which significantly affects the quality of sleep. ①Acute rhinitis: It often appears as an acute upper respiratory tract infection with acute congestion of the nasal mucosa and nasal secretions that are initially clear watery and then turn mucous or mucopurulent. ② chronic simple rhinitis: nasal congestion is alternating or intermittent, nasal secretions are small and can be thin or viscous,. ③ chronic hypertrophic rhinitis: nasal congestion for progressive or persistent nasal congestion, less snot, examination can be seen nasal turbinate hypertrophy, the surface is not flat or like mulberry, poor elasticity, insensitive to 1% ephedrine contraction response. ④Atrophic rhinitis: nasal congestion is mostly caused by the accumulation of nasal scabs, emitting foul odor, also known as odoriferous rhinitis, and the examination shows that the turbinates are atrophied and small. ⑤ Allergic rhinitis: divided into intermittent and persistent (usually called seasonal and perennial), manifested as rhinitis, sneezing, and clear watery snot, examination can be seen in the nasal mucosa pale edema, inferior turbinate enlargement. (6) Deviated nasal septum or cremaster: nasal congestion is sometimes light and sometimes heavy, and nasal congestion is obvious on one side when it is obviously deviated, which can lead to nasal bleeding. (7) Acute and chronic sinusitis: manifested as nasal congestion, pus, sinus mouth blockage is no pus outflow, so there are symptoms such as headache and head swelling. Examination sees congestion and swelling of the nasal mucosa, and purulent secretions in the middle nasal passage or olfactory fissure. ⑧ Nasal polyp: progressive and persistent nasal congestion, occlusive nasal sound, may be accompanied by pus, lyrium-like neoplasm is seen in the nasal cavity. ⑨ Nasal neoplasm: most of them show unilateral nasal progressive and persistent nasal congestion, neoplasm can be seen in the nasal cavity, pathological biopsy can clarify whether the neoplasm is benign or malignant. 2, which poor sleep quality should be highly alert to nasal diseases caused by? There are various reasons affecting the quality of sleep: environmental factors, dietary habits, life style and so on, and nasal diseases are only one of the reasons. How can patients self-judge whether their sleep snoring is related to nasal diseases? Simply speaking, if you have the following symptoms, you should consider nasal disease: ① Unilateral or bilateral nasal congestion, which can be intermittent or continuous. (2) Nasal congestion accompanied by itching, sneezing and clear runny nose. ③ nasal congestion with a heavy feeling in the head, which may be accompanied by runny nose. ④Occlusive rhinitis ⑤Decreased sense of smell 3. What tests should be done for those who suspect that poor sleep quality is caused by nasal diseases? If snoring is suspected to be caused by nasal diseases, patients are advised to visit the ENT department for specific examinations including: ① Routine nasal examination, which can understand the general condition of the nasal cavity. ②Outpatient nasal endoscopy to get a glimpse of deep nasal lesions, including polyps or tumors. ③Sinus CT examination to understand the situation inside the sinuses.
