Reduction of hypertrophied turbinates, correction of nasal septum deviation, removal of polyps, sectioning of the parasympathetic secretomotor fiber to nose (vidian neurectomy) for controlling refractory excessive rhinorrhea.

The avoidance of inciting factors such as sudden changes in temperature, humidity, or blasts of air or dust is helpful.

Intranasal application of antihistamines, corticosteroids, or anticholinergics may also be used for vasomotor rhinitis. Intranasal cromolyn sodium may be used in patients older than two years.

Astelin (Azelastine) "is indicated for symptomatic treatment of vasomotor rhinitis including rhinorrhea, nasal congestion, and post nasal drip in adults and children 12 years of age and older."

The preferred treatment for many patients is desensitization to aspirin, undertaken at a clinic or hospital specializing in such treatment. In the United States, the Scripps Clinic in San Diego, CA, the Massachusetts General Hospital in Boston, MA, the Brigham and Women's Hospital in Boston, MA, National Jewish Hospital in Denver and Stanford University Adult ENT Clinic have allergists who routinely perform aspirin desensitization procedures for patients with aspirin-induced asthma. Patients who are desensitized then take a maintenance dose of aspirin daily and while on daily aspirin they often have reduced need for supporting medications, fewer asthma and sinusitis symptoms than previously, and many have an improved sense of smell. Desensitization to aspirin reduces the chance of nasal polyp recurrence, and can slow the regrowth of nasal polyps. Even patients desensitized to aspirin may continue to need other medications including nasal steroids, inhaled steroids, and leukotriene antagonists.

Leukotriene antagonists and inhibitors (montelukast, zafirlukast, and zileuton) are often helpful in treating the symptoms of aspirin-induced asthma. Some patients require oral steroids to alleviate asthma and congestion, and most patients will have recurring or chronic sinusitis due to the nasal inflammation.

Often surgery is required to remove nasal polyps, although they typically recur, particularly if aspirin desensitization is not undertaken. 90% of patients have been shown to have recurrence of nasal polyps within 5 years after surgery, with 47% requiring revision surgery in the same time period.

In most cases treatment for rhinorrhea is not necessary since it will clear up on its own—especially if it is the symptom of an infection. For general cases blowing your nose can get rid of the mucus buildup. Though blowing may be a quick-fix solution, it would likely proliferate mucosal production in the sinuses, leading to frequent and higher mucus buildups in the nose. Alternatively, saline nasal sprays and vasoconstrictor nasal sprays may also be used, but may become counterproductive after several days of use, causing rhinitis medicamentosa.

In recurring cases, such as those due to allergies, there are medicinal treatments available. For cases caused by histamine buildup, several types of antihistamines can be obtained relatively cheaply from drugstores.

People who prefer to keep clear nasal passages, such as singers, who need a clear nasal passage to perform, may use a technique called "nasal irrigation" to prevent rhinorrhea. Nasal irrigation involves rinsing the nasal cavity regularly with salty water or store bought saline solutions.

The treatment of RM involves withdrawal of the offending nasal spray or oral medication. Both a "cold turkey" and a "weaning" approach can be used. Cold turkey is the most effective treatment method, as it directly removes the cause of the condition, yet the time period between the discontinuation of the drug and the relief of symptoms may be too long and uncomfortable for some individuals (particularly when trying to go to sleep when they are unable to breathe through their nose).

A benefit of the gradual “weaning” approach is that it helps preserve normal nasal airflow during the withdrawal process. United States Patent Number 5,988,870 was issued for a method and apparatus used to facilitate the precise titration and gradual withdrawal of decongestant nasal sprays containing addictive compounds. The system is sold under the brand name Rhinostat.

The use of over-the-counter (OTC) saline nasal sprays may help open the nose without causing RM if the spray does not contain a decongestant. Symptoms of congestion and runny nose can often be treated with corticosteroid nasal sprays under the supervision of a physician. For very severe cases, oral steroids or nasal surgery may be necessary.

For RM caused by topical decongestants, there are anecdotal reports of persons having success by withdrawing treatment from one nostril at a time.

A study has shown that the anti-infective agent benzalkonium chloride, which is frequently added to topical nasal sprays as a preservative, aggravates the condition by further increasing the rebound swelling.

For unconfirmed acute sinusitis, intranasal corticosteroids have not been found to be better than a placebo either alone or in combination with antibiotics. For cases confirmed by radiology or nasal endoscopy, treatment with corticosteroids alone or in combination with antibiotics is supported. The benefit, however, is small.

There is only limited evidence to support short treatment with oral corticosteroids for chronic rhinosinusitis with nasal polyps.

The treatment of nasal congestion frequently depends on the underlying cause.

Alpha-adrenergic agonists are the first treatment of choice. They relieve congestion by constricting the blood vessels in the nasal cavity, thus resulting in relieved symptoms. Examples include oxymetazoline and phenylephrine.

Both influenza and the common cold are self-limiting conditions that improve with time; however, drugs such as acetaminophen (paracetamol), aspirin, and ibuprofen may help with the discomfort.

A cause of nasal congestion may also be due to an allergic reaction caused by hay fever, so avoiding allergens is a common remedy if this becomes a confirmed diagnosis. Antihistamines and decongestants can provide significant symptom relief although they do not cure hay fever. Antihistamines may be given continuously during pollen season for optimum control of symptoms. Topical decongestants should only be used by patients for a maximum of 3 days in a row, because rebound congestion may occur in the form of rhinitis medicamentosa.

Nasal decongestants target discomfort directly. These come as nasal sprays like naphazoline (Privine), oxymetazoline (Afrin, Dristan, Duramist), as inhalers, or phenylephrine (Neo-Synephrine, Sinex, Rhinall) or as oral pills (Bronkaid, Sudafed, Neo-Synephrine, Sinex, Rhinall). Oral decongestants may be used for up to a week without consulting a doctor, with the exception of Bronkaid and Sudafed, which can be taken as long as needed, but nasal sprays can also cause "rebound" (Rhinitis medicamentosa) and worsen the congestion if taken for more than a few days. Therefore, you should only take nasal sprays when discomfort cannot be remedied by other methods, and never for more than three days.

If an infant is unable to breathe because of a plugged nose, a nasal aspirator may be useful to remove the mucus. The mucus might be thick and sticky, making it difficult to expel from the nostril.

Recommended treatments for most cases of sinusitis include rest and drinking enough water to thin the mucus. Antibiotics are not recommended for most cases.

Breathing low-temperature steam such as from a hot shower or gargling can relieve symptoms. There is tentative evidence for nasal irrigation. Decongestant nasal sprays containing oxymetazoline may provide relief, but these medications should not be used for more than the recommended period. Longer use may cause rebound sinusitis. It is unclear if nasal irrigation, antihistamines, or decongestants work in children with acute sinusitis.

Treatment of atrophic rhinitis can be either medical or surgical.

Medical measures include:

- Nasal irrigation using normal saline

- Nasal irrigation and removal of crusts using alkaline nasal solutions prepared by dissolving a spoonful of powder containing one part sodium bicarbonate, one part sodium biborate and two part sodium chloride.

- 25% glucose in glycerine can be applied to the nasal mucosa to inhibit the growth of proteolytic organisms which produce foul smell.

- Local antibiotics, such as chloromycetine.

- Vitamin D (Kemicetine).

- Estradiol spray for regeneration of seromucinous glands and vascularization of mucosa.

- Systemic streptomycin (1g/day) against Klebsiella organisms.

- Oral potassium iodide for liquefaction of secretion.

- Placental extract injected in the submucosa.

Surgical interventions include:

- Young's operation.

- Modified Young's operation.

- Narrowing of nasal cavities, submucosal injection of Teflon paste, section and medial displacement of the lateral wall of the nose.

- Transposition of parotid duct to maxillary sinus or nasal mucosa.

Treatment for fungal sinusitis can include surgical debridement; helps by slowing progression of disease thus allowing time for recovery additionally we see the options below:

- In the case of invasive fungal sinusitis, echinocandins, voriconazole, and amphoterecin (via IV) may be used

- For allergic fungal sinusitis, systemic corticosteroids like prednisolone, methylprednisolone are added for their anti-inflammatory effect, bronchodilators and expectorants help to clear secretions in the sinuses.

Common issues that lead to overuse of topical decongestants:

- Deviated septum

- Upper respiratory tract infection

- Vasomotor rhinitis

- Cocaine use and other stimulant abuse

- Pregnancy (these products are not considered safe for pregnancy)

- Chronic rhinosinusitis

- Hypertrophy of the inferior turbinates

Rhinorrhea can be a symptom of other diseases, such as the common cold or influenza. During these infections, the nasal mucous membranes produce excess mucus, filling the nasal cavities. This is to prevent infection from spreading to the lungs and respiratory tract, where it could cause far worse damage. It has also been suggested that rhinorrhea is a result of viral evolution, and may be a response that is not useful to the host, but which has evolved by the virus to maximise its own infectivity. Rhinorrhea caused by these infections usually occur on circadian rhythms. Over the course of a viral infection, sinusitis (the inflammation of the nasal tissue) may occur, causing the mucous membranes to release more mucus. Acute sinusitis consists of the nasal passages swelling during a viral infection. Chronic sinusitis occurs when one or more nasal polyps appear. This can be caused by a deviated septum as well as a viral infection.

First-generation antihistamine has been suggested as first-line therapy to treat post-nasal drip.

The most important aspect of treatment is improving denture hygiene, i.e. removing the denture at night, cleaning and disinfecting it, and storing it overnight in an antiseptic solution. This is important as the denture is usually infected with "C. albicans" which will cause re-infection if it is not removed. Substances which are used include solutions of alkaline peroxides, alkaline hypochlorites (e.g. hypochlorite, which may over time corrode metal components of dental appliances), acids (e.g. benzoic acid), yeast lytic enzymes and proteolytic enzymes (e.g. alcalase protease). The other aspect of treatment involves resolution of the mucosal infection, for which topical antifungal medications are used (e.g. nystatin, amphotericin, miconazole, fluconazole or itraconazole). Often an antimicrobial mouthwash such as chlorhexidine is concurrently prescribed. Possible underlying disease (diabetes, HIV) should be treated where possible.

Treatment is cause-related, but also symptomatic if the underlying cause is unknown or not correctable. It is also important to note that most ulcers will heal completely without any intervention. Treatment can range from simply smoothing or removing a local cause of trauma, to addressing underlying factors such as dry mouth or substituting a problem medication. Maintaining good oral hygiene and use of an antiseptic mouthwash or spray (e.g. chlorhexidine) can prevent secondary infection and therefore hasten healing. A topical analgesic (e.g. benzydamine mouthwash) may reduce pain. Topical (gels, creams or inhalers) or systemic steroids may be used to reduce inflammation. An antifungal drug may be used to prevent oral candidiasis developing in those who use prolonged steroids. People with mouth ulcers may prefer to avoid hot or spicy foods, which can increase the pain. Self-inflicted ulceration can be difficult to manage, and psychiatric input may be required in some people.

Anti-tumour necrosis factor α antagonists (e.g. infliximab)

Dietary restriction of a particular suspected or proven antigen may be involved in the management of OFG, such as cinnamon or benzoate-free diets.

Treatment includes fluid intake, good oral hygiene and gentle debridement of the mouth, as well as oral acyclovir. In healthy individuals the lesions heal spontaneously in 7–14 days without scarring.

Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels.

Nasal decongestants target the discomfort directly. These come as nasal sprays, inhalers, and as oral pills.

Nasal congestion has many causes and can range from a mild annoyance to a life-threatening condition. Most people prefer to breathe through the nose (historically referred to as "obligate nasal breathers"). Nasal congestion in an infant in the first few months of life can interfere with breastfeeding and cause life-threatening respiratory distress; in older children and adolescents it is often just an annoyance but can cause other difficulties.

Nasal congestion can interfere with the hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea. In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia, as well as right-sided heart failure. The problem usually resolves after surgery to remove the adenoids and tonsils, however the problem often relapses later in life due to craniofacial alterations from chronic nasal congestion.

Nasal congestion can also cause mild facial and head pain, and a degree of discomfort, often from allergies or the common cold.

The first line of treatment for nasal polyps is topical steroids. Steroids decrease the inflammation of the sinus mucosa to decrease the size of the polyps and improve symptoms. Topical preparations are preferred in the form of a nasal spray, but are often ineffective for people with many polyps. Steroids by mouth often provide drastic symptom relief, but should not be taken for long periods of time due to their side effects. Because steroids only shrink the size and swelling of the polyp, people often have recurrence of symptoms once the steroids are stopped. Decongestants do not shrink the polyps, but can decrease swelling and provide some relief. Antibiotics are only recommended if the person has a co-occurring bacterial infection.

In people with nasal polyps caused by aspirin or NSAIDs, avoidance of these medications will help with symptoms. Aspirin desensitization has also been shown to be beneficial.

Denture-related stomatitis is usually a harmless condition with no long term consequences. It usually resolves with simple measures such as improved denture hygiene or topical antifungal medication. In severely immunocompromised individuals (e.g. those with HIV), the infection may present a more serious threat.

Endoscopic sinus surgery with removal of polyps is often very effective for most people providing rapid symptom relief. Endoscopic sinus surgery is minimally-invasive and is done entirely through the nostril with the help of a camera. Surgery should be considered for those with complete nasal obstruction, uncontrolled runny nose, nasal deformity caused by polyps or continued symptoms despite medical management. Surgery serves to remove the polyps as well as the surrounding inflamed mucosa, open obstructed nasal passages, and clear the sinuses. This not only removes the obstruction caused by the polyps themselves, but allows medications such as saline irrigations and topical steroids to become more effective.

Surgery lasts approximately 45 minutes to 1 hour and can be done under general or local anesthesia. Most patients tolerate the surgery without much pain, though this can vary from patient to patient. The patient should expect some discomfort, congestion, and drainage from the nose in the first few days after surgery, but this should be mild. Complications from endoscopic sinus surgery are rare, but can include bleeding and damage to other structures in the area including the eye or brain.

Many physicians recommend a course of oral steroids prior to surgery to reduce mucosal inflammation, decrease bleeding during surgery, and help with visualization of the polyps. Nasal steroid sprays should be used preventatively after surgery to delay or prevent recurrence. People often have recurrence of polyps even following surgery. Therefore, continued follow up with a combination of medical and surgical management is preferred for the treatment of nasal polyps.

Throughout history treatment relied primarily on β-lactam antibiotics. In the 1960s nearly all strains of "S. pneumoniae" were susceptible to penicillin, but more recently there has been an increasing prevalence of penicillin resistance especially in areas of high antibiotic use. A varying proportion of strains may also be resistant to cephalosporins, macrolides (such as erythromycin), tetracycline, clindamycin and the quinolones. Penicillin-resistant strains are more likely to be resistant to other antibiotics. Most isolates remain susceptible to vancomycin, though its use in a β-lactam-susceptible isolate is less desirable because of tissue distribution of the drug and concerns of development of vancomycin resistance. More advanced beta-lactam antibiotics (cephalosporins) are commonly used in combination with other drugs to treat meningitis and community-acquired pneumonia. In adults recently developed fluoroquinolones such as levofloxacin and moxifloxacin are often used to provide empiric coverage for patients with pneumonia, but in parts of the world where these drugs are used to treat tuberculosis resistance has been described.

Susceptibility testing should be routine with empiric antibiotic treatment guided by resistance patterns in the community in which the organism was acquired. There is currently debate as to how relevant the results of susceptibility testing are to clinical outcome. There is slight clinical evidence that penicillins may act synergistically with macrolides to improve outcomes.

Though it is widely held that fungal infections of the nose and paranasal sinuses are not common, most agree that their frequency has been increasing over past decades.

Biopsy screening although necessary is not mandatory most dentist can visually examine the area and proceed with the proper course of treatment.

Treatment includes:

- Abstention from chewing areca nut (also known as betel nut) and tobacco

- Minimizing consumption of spicy foods, including chiles

- Maintaining proper oral hygiene

- Supplementing the diet with foods rich in vitamins A, B complex, and C and iron

- Forgoing hot fluids like tea, coffee

- Forgoing alcohol

- Employing a dental surgeon to round off sharp teeth and extract third molars

Treatment also includes following:

- The prescription of chewable pellets of hydrocortisone (Efcorlin); one pellet to be chewed every three to four hours for three to four weeks

- 0.5 ml intralesional injection Hyaluronidase 1500 IU mixed in 1 ml of Lignocaine into each buccal mucosa once a week for 4 weeks or more as per condition

- 0.5 ml intralesional injection of Hyaluronidase 1500 IU and 0.5 ml of injection Hydrocortisone acetate 25 mg/ml in each buccal mucosa once a week alternatively for 4 weeks or more as per condition

- Submucosal injections of hydrocortisone 100 mg once or twice daily depending upon the severity of the disease for two to three weeks

- Submucosal injections of human chorionic gonadotrophins (Placentrax) 2-3 ml per sitting twice or thrice in a week for three to four weeks

- Surgical treatment is recommended in cases of progressive fibrosis when interincisor distance becomes less than . (Multiple release incisions deep to mucosa, submucosa and fibrotic tissue and suturing the gap or dehiscence so created by mucosal graft obtained from tongue and Z-plasty. In this procedure multiple deep z-shaped incisions are made into fibrotic tissue and then sutured in a straighter fashion.)

- Pentoxifylline (Trental), a methylxanthine derivative that has vasodilating properties and increases mucosal vascularity, is also recommended as an adjunct therapy in the routine management of oral submucous fibrosis.

- IFN-gamma is antifibrotic cytokine which alters collagen synthesis and helps in OSF.

- Colchicine tablets 0.5 mg twice a day

- Lycopene, 16 mg a day helps in improvement of OSF

The treatment of patients with oral submucous fibrosis depends on the degree of clinical involvement. If the disease is detected at a very early stage, cessation of the habit is sufficient. Most patients with oral submucous fibrosis present with moderate-to-severe disease. Severe oral submucous fibrosis is irreversible. Moderate oral submucous fibrosis is reversible with cessation of habit and mouth opening exercise. Current modern day medical treatments can make the mouth opening to normal minimum levels of 30 mm mouth opening with proper treatment.
