A deviated nasal septum is quite common in the general population and is often asymptomatic, but some individuals can develop chronic nasal obstruction, recurrent epistaxis and are predisposed to chronic sinusitis. The diagnosis can be made during physical examination and through imaging procedures.
Presentation
More than 60% of the adult population is estimated to suffer from a deviated nasal septum according to certain reports [1], but the clinical presentation varies depending on the location and severity of nasal septum deviation. Individuals may often be asymptomatic, but the most common signs include epistaxis, increased nasal crusting, altered nasal respiration and the necessity for mouth breathing due to obstruction of the nasal canal, and chronic or recurrent sinusitis, which is frequently encountered among patients in whom deviation causes obstruction of the ostium of the paranasal sinus [2] [3] [4]. Repetitive sneezing, snoring and sleep apnea are also reported, while less common symptoms include facial pain, variable loss of olfaction and headaches [3]. Recent trauma to the nose and face is the key risk factor for deviation, but congenital causes may be responsible as well. Neonates and infants commonly develop deviation of the nasal septum due to trauma during vaginal delivery [2], and in this population, poor feeding and choking due to the presence of food in the respiratory tract are reported in the case of a severe deviation, in addition to nasal obstruction and epistaxis [2]. Various anatomical anomalies, such as increased anterior facial height, mandible with increased overjet and constricted transverse maxillary dimension and a retrognathic maxilla have been documented in patients suffering from nasal septum deviation [4].

Snoring
Some patients had associated pre-operative symptoms of snoring (57.3%), headache (48.0%), rhinorrhoea (38.7%), sneezing (30.7%), hyposmia (30.7%) and epistaxis (21.3%). [ncbi.nlm.nih.gov]

Repetitive sneezing, snoring and sleep apnea are also reported, while less common symptoms include facial pain, variable loss of olfaction and headaches. [symptoma.com]
A deviated nasal septum can cause sinus infections, sleep apnea, snoring, sneezing attacks, facial pain, nosebleeds, breathing difficulties and a slight to serious loss of sense of smell. [respifacile.com]
A severely deviated nasal septum can block one side of your nose and reduce airflow, which can cause difficulty breathing, snoring, recurrent sinus infections, crusting or nosebleeds. [ent-sd.com]

Excessive Sneezing
The incidence of excessive sneezing in this study is 15% and these patients were also having allergic rhinitis. The study made by Haytham Kubba, Brian J.G. showed an incidence of 12% sneezing [11]. Thickened septum is seen in 3% of cases. Table 1. [file.scirp.org]

Mitral Valve Prolapse
Mitral valve prolapse (MVP) is a characteristic of generalized collagen abnormality. Nasal septum (NS) is constituted by osseous and cartilaginous septums that are highly rich in collagen. [ncbi.nlm.nih.gov]

Mouth Breathing
Individuals may often be asymptomatic, but the most common signs include epistaxis, increased nasal crusting, altered nasal respiration and the necessity for mouth breathing due to obstruction of the nasal canal, and chronic or recurrent sinusitis, which [symptoma.com]
Other symptoms of a deviated septum include nasal drainage, nosebleeds, mouth breathing, and facial pressure. A crooked or deviated septum is not usually caused by an injury. [nw-ent.com]
A deviated septum and swelling of the intranasal tissues can negatively affect a patient’s quality of sleep and can lead to dry mouth due to chronic mouth breathing. [pacificneuroscienceinstitute.org]
If the blockage is severe, it may force mouth-breathing at night, which can worsen sleep disorders. [entnet.org]
Discussion Septal deviation can cause symptoms such as nasal obstruction, mouth breathing with variable symptoms such as headache and olfactory disorders. [ncbi.nlm.nih.gov]

Bony Swelling
The turbinates are bony swellings on the outer walls of the nasal cavities. Both the nasal septum and turbinates are covered with a delicate mucosal tissue that regularly swells to control airflow in the nose. [nycfacemd.com]

Epistaxis
Some patients had associated pre-operative symptoms of snoring (57.3%), headache (48.0%), rhinorrhoea (38.7%), sneezing (30.7%), hyposmia (30.7%) and epistaxis (21.3%). [ncbi.nlm.nih.gov]
A deviated nasal septum is quite common in the general population and is often asymptomatic, but some individuals can develop chronic nasal obstruction, recurrent epistaxis and are predisposed to chronic sinusitis. [symptoma.com]
Symptomatic patients can present with unilateral nasal obstruction or less commonly epistaxis, obstructive sinusitis, and/or pain/pressure symptoms 4. Etiology Nasal septum deviation can be congenital or acquired. [radiopaedia.org]
It may also predispose to repeated epistaxis from the vessels stretched on its convex surface. 5. Thickening of Nasal Septum It may be due to organized haematoma or overriding of dislocated septal cartilage fragments. 4. [slideshare.net]
This obstruction may predispose the patient to sinusitis, infection and epistaxis (nose bleeds). Treatment Treatment of a deviated septum is based on the patient's symptoms. [healthcentral.com]
Workup
The diagnosis rests on suspecting a deviated nasal septum based on signs and symptoms that are reported by the patient, which is why a detailed patient history can often provide sufficient clues to develop clinical suspicion. Information about recent trauma, chronicity of symptoms, as well as their severity, can be helpful. A thorough physical examination comprised of a full ear, nose, and throat evaluation should follow, and anterior rhinoscopy or nasal endoscopy can confirm the diagnosis, as they provide a direct view into the nasal cavity [2]. Additional procedures have been proposed in the workup, including acoustic rhinometry (evaluation of the nasal cavity by means of acoustic reflection), rhinomanometry (a procedure that measures the resistance of the nasal cavity) and nasal spectral sound analysis, but their specificity and sensitivity remain to be solidified in regular practice [2]. More advanced imaging studies, such as computed tomography (CT), may be useful for preoperative assessment and determination of potential anatomical anomalies, but they are not superior to the standard physical examination when it comes to detecting a deviated nasal septum [5].

Treatment
[citation needed] Currently, the most gentle and effective treatment is laser septochondroplasty for the septal cartilage segment deformity and ultrasound septoplasty — effective for the septal cartilage and bone deformation. [en.wikipedia.org]

Prognosis
Treatment and prognosis If medical management fails, the most common surgical procedure performed is septoplasty 4.5. Promoted articles (advertising) [radiopaedia.org]
Prognosis Surgical repair is curative and carries little risk. Chronic infection can be painful and lead to complications until it is resolved. If there is continued obstruction, the infection will very likely return. [medical-dictionary.thefreedictionary.com]
Prognosis In the most cases, surgery is successful. However, a small percentage of patients choose to have a second surgery for cosmetic reasons or to improve airflow. [drugs.com]
Etiology
Etiology Nasal septum deviation can be congenital or acquired. The most common acquired cause is trauma from motor vehicle collisions, sports-related injuries, and altercations. [radiopaedia.org]

Pathophysiology
Due to changes in pathophysiology the patient is more susceptible to chronic rhinitis/rhinosinusitis. KEYWORDS: Chronic inflammation; Microscopy; Nasal mucosa; Nasal septum; Squamous metaplasia [ncbi.nlm.nih.gov]

However, the main pathophysiology of these chronic conditions is poorly described and seems to be multifactorial. [cyberleninka.org]
Prevention
Medications such as antihistamines, decongestants, and nasal steroid sprays can reduce congestion and inflammation to help prevent a runny nose and postnasal drip. [eoent.com]
Packing does not prevent bleeding but will prevent topical decongestants from reaching bleeding sites. Packing also keeps nasal saline from cleaning the inside of the nose. [nycfacemd.com]
Though some surgeons still use packing to prevent postoperative bleeding, the National Institute of Health states that, “Nasal packing has several risks for patients and septoplasty can be safely performed without [it].” [rhinoplasty.com]
