A deviated septum from birth means the wall inside the nose formed off-center before birth or shifted during delivery. This wall separates the two nasal passages, so one side may be narrower. Many people have no symptoms and need no treatment. If it causes ongoing trouble breathing, nosebleeds, or noisy sleep, a healthcare professional can check the nose and discuss ways to help.
What Does It Mean to Be Born With a Deviated Septum?
The nasal septum is the thin wall made of cartilage and bone that divides the inside of the nose into two passages. Ideally, it sits close to the middle, allowing air to pass through both sides. When the wall bends or shifts to one side, it is called a deviated septum.
A person can have this condition from birth without knowing it. The septum may be off-center even when the outside of the nose looks normal. In other cases, the nose may also appear crooked. The amount of deviation does not necessarily determine how easily someone can breathe, because swelling and other changes inside the nose can also affect airflow.
How Can a Deviated Septum Develop Before or During Birth?
A deviated septum can be present at birth for more than one reason. According to Mayo Clinic, the septum may develop off-center while a baby is growing in the womb, or an injury during childbirth may move it out of position.
When the deviation is congenital, meaning present from birth, it does not necessarily indicate that something went wrong during pregnancy or delivery. The timing and cause may not be clear from the appearance of the nose alone. A clinician can assess the structure of the nasal passages and consider the person's symptoms and medical history to determine whether the deviation is affecting breathing.
What Symptoms Can Occur With a Deviated Septum From Birth?
Some people have no noticeable problems throughout their lives. Others experience symptoms during childhood or notice breathing difficulties more clearly as they grow older. The Cleveland Clinic explains that a deviated septum can narrow one or both nasal passages and may contribute to breathing problems or nasal congestion.
Possible symptoms include:
- Difficulty breathing through the nose: One nostril may feel more blocked than the other, particularly when trying to breathe deeply or during sleep.
- Ongoing nasal congestion: A narrow nasal passage may make a blocked nose more noticeable, especially when allergies, a cold, or other irritation causes swelling.
- Frequent nosebleeds: Air passing through the nose can dry the lining around the septum in some people, making bleeding more likely.
- Noisy breathing during sleep: A narrowed nasal passage may contribute to snoring or other noisy breathing, although many other conditions can cause these symptoms.
- Mouth breathing: Some people breathe through their mouths when nasal airflow is limited, particularly at night.
- Repeated sinus problems: In some cases, a deviation may affect sinus drainage and contribute to recurring sinus infections.
These experiences do not establish that a deviated septum is the cause. Allergies, enlarged tissues inside the nose, infections, and other structural conditions can produce similar symptoms. For this reason, persistent or disruptive nasal symptoms deserve an appropriate assessment.
Can a Deviated Septum From Birth Cause Problems Later in Life?
Yes, symptoms may become more noticeable later even when the deviation has been present since birth. A naturally narrow nasal passage can become more obstructed when the tissues lining the nose swell because of allergies or an infection. Age-related changes in nasal structures can also affect an existing deviation.
For example, a child may breathe comfortably through the nose for years but later experience more congestion during allergy season. An adult who has always had one narrower nasal passage may also notice increasing difficulty when a cold causes additional swelling. These changes do not necessarily mean the septum has suddenly become more crooked.
A deviated septum may also occur alongside other nasal conditions. A healthcare professional considers these possibilities rather than assuming that the septum explains every episode of congestion, sleep disturbance, or breathing difficulty.
How Do Doctors Check for a Deviated Septum Present From Birth?
Assessment usually begins with questions about breathing, when symptoms started, whether one side feels more blocked, any history of nasal injury, and whether allergies or sinus problems are present. For infants and children, the clinician may also ask caregivers about noisy breathing, sleep, feeding when relevant, and how symptoms affect everyday activities.
According to Mayo Clinic's guidance on diagnosis and treatment, a healthcare professional can examine the inside of the nose using a light and, when needed, a tool to gently open the nostrils. A small lighted scope may be used to view areas farther inside the nasal passages.
The examination helps the clinician identify the septum's position and consider whether other causes of blockage may be present. Additional tests depend on the findings and the person's symptoms. A visible deviation alone does not mean that treatment is necessary; its effect on breathing and daily life is an important part of the decision.
Does a Deviated Septum From Birth Need Treatment?
Not always. If the deviation does not cause meaningful symptoms or interfere with normal activities, treatment may not be necessary. Regular surgery is not required simply because the septum is off-center.
When symptoms are related partly to swelling from allergies or other nasal inflammation, a clinician may recommend medicines to manage that swelling. Depending on the cause, these may include antihistamines, decongestants, or nasal steroid sprays. Such treatments can ease congestion, but they do not physically straighten the septum.
If structural narrowing continues to interfere with breathing despite appropriate medical treatment, an ear, nose, and throat (ENT) specialist may discuss surgery. The decision depends on examination findings, symptom impact, other possible causes, and the person's age and overall circumstances.
When Is Surgery Considered for a Congenital Deviated Septum?
The operation used to straighten a deviated septum is called septoplasty. During the procedure, a surgeon reshapes or repositions the bone and cartilage inside the nose to improve the alignment of the septum and, when appropriate, the space available for airflow.
Mayo Clinic's guide to septoplasty explains that the procedure is intended to correct the crooked internal wall. It may be considered when a deviated septum causes ongoing symptoms, particularly when breathing difficulties remain after other contributing problems have been addressed. Medicines cannot correct the underlying structural bend.
Before surgery, the specialist should explain the expected benefits, limitations, recovery process, and possible complications. Septoplasty may improve nasal airflow, but it cannot guarantee that every symptom will disappear, particularly when allergies or other conditions also affect breathing.
How Does Treatment Differ for Children?
Children need particular consideration because their noses and facial structures are still growing. The Children's Hospital of Philadelphia notes that septoplasty is often delayed until the teenage years because of facial growth, although the timing depends on the child's condition and clinical needs.
A mild, symptom-free deviation generally does not require an operation. When a child has significant breathing problems or other persistent difficulties, an ENT specialist can assess the potential benefits and risks of treatment before facial growth is complete. Surgery at a younger age may be considered in selected cases when the expected benefit justifies it.
For adults, the decision is generally based on the severity and persistence of symptoms, examination findings, other contributing conditions, and the likely benefits of correcting the septum. Being born with the condition does not, by itself, determine whether surgery is appropriate.
When Should You Seek Medical Assessment?
Arrange an appointment with a healthcare professional if nasal blockage is persistent, frequently returns, disrupts sleep, or makes normal breathing difficult. Repeated nosebleeds or recurring sinus infections also deserve assessment, particularly when symptoms are affecting everyday life or do not improve with appropriate treatment.
For a baby or child, persistent noisy breathing or other ongoing nasal breathing difficulties should be discussed with a pediatrician or ENT specialist. If a baby has difficulty breathing or feeding, seek urgent medical care rather than assuming a deviated septum is responsible, because several conditions can cause these problems.
The main consideration is not simply whether the septum is crooked, but whether it is causing a meaningful problem and whether the symptoms are truly related to it. A clinical assessment can help determine whether observation, treatment for nasal swelling, or a discussion about surgery is the most appropriate next step.
