Nasal Bone

The nasal bone consists of paired thin bone structures located in the upper part of our nose, right at the center of our face. Although their size is small (each approximately 2–3 cm in length and 1 cm in width), they are extremely important due to the role they play in facial aesthetics and respiratory functions. They function almost like the “keystone” of our face.

Even though we may not be aware of it in daily life, the nasal bones play a role in every breath we take, in every facial expression, and in our mimic movements. These bones, which determine the shape of the nose, are not only important aesthetically but also vitally important functionally because they form the starting point of the airway. When fractured as a result of trauma or when congenital deformities are present, both appearance and breathing quality can be seriously affected.

What Is the Structure and Function of the Nasal Bone?

The nasal bones are among the thinnest and most fragile bones of the skull. When viewed from the outside, these bones form the bridge of the nose and are actually triangular in shape. They meet at the midline, forming a roof-like structure. Beneath this roof lies the cartilage tissue that forms the internal structure of the nose.

Structurally, the outer surface of the nasal bones has a slightly convex form, while the inner surface is concave. Small holes (foramina) are present on their outer surfaces, through which blood vessels and nerves pass. Thanks to these vessels, the bone maintains its vitality and has healing potential when damaged.

The main functions of the nasal bones are:

• Providing structural support to the upper part of the nose
• Contributing to facial appearance
• Protecting the initial part of the airway
• Shielding the nasal cavity from external trauma
• Supporting the region where the sense of smell occurs

In clinical practice, a common observation is that the structural characteristics of the nasal bones can vary greatly from person to person. In some individuals, they may be thicker and wider; in others, thinner and more delicate. These differences directly affect the risk of fracture in trauma cases and the surgical approach in interventions.

How Are the Nasal Bones Related to Surrounding Facial Structures?

Because the nasal bones are located at the center of the face, they are adjacent to many important anatomical structures. These relationships are highly significant both functionally and during surgical interventions.

Superiorly, they articulate with the frontal bone (os frontale). This connection is called the “nasofrontal suture.” Laterally, they join with the frontal process of the maxilla, forming the “nasomaxillary suture.” Internally, they are adjacent to the perpendicular plate (lamina perpendicularis) of the ethmoid bone, which forms the middle partition of the nose.

The lower end of the nasal bones connects with the upper lateral cartilages. This transition zone is particularly important in nasal trauma because the bone-cartilage junction is often the most common site of fractures.

In my clinical experience, nasal bone trauma is rarely isolated. Surrounding structures are often affected as well. For example, a severe blow may result not only in a nasal bone fracture but also in a maxillary fracture or septal deviation. Therefore, during examination and imaging studies of the nasal region, we always evaluate the relationship of the nasal bone with adjacent structures.

What Is the Development and What Are the Variations of the Nasal Bone?

The development of the nasal bones begins in the womb. During the embryological period, around the 6th–8th weeks of facial development, they originate from a structure called the “frontonasal prominence.” Small at birth, these bones continue to grow until adolescence and reach their final size at approximately 18 years of age.

Throughout life, the nasal bones continue to change. With aging, resorption (bone loss) occurs in the nasal bones, as in all facial bones. This can lead to changes in nasal appearance in advanced age and sometimes results in what is referred to as the “aging nose.”

Common anatomical variations of the nasal bones include:

• Asymmetrical size (one side being larger than the other)
• Differences in bone thickness
• Variations in the angle at which the nasal bones join
• Additional sutures or small accessory bones

An interesting condition I have encountered in clinical practice is the congenital absence or extreme smallness of the nasal bones in some patients. This rare condition, called “nasal aplasia,” is usually seen together with other craniofacial anomalies.

These anatomical variations directly influence the surgical approach in rhinoplasty (nose aesthetics) or post-traumatic reconstruction procedures. Each patient’s nasal bone structure is unique and requires a personalized treatment plan. A standard approach may lead to unsuccessful outcomes in patients with different anatomical variations.

What Role Does the Nasal Bone Play in Facial Aesthetics and Breathing?

Because the nasal bones are located at the center of the face, they serve as a “balance point” in facial aesthetics. These bones determine the shape and height of the upper part of the nose and directly affect facial proportions and overall appearance. As emphasized in Leonardo da Vinci’s classical studies on facial proportions, the position and angle of the nasal bones play a critical role in achieving facial “golden ratio” harmony.

In my clinical practice, I frequently observe that the nose is the facial area patients focus on most when looking in the mirror. Even the smallest asymmetry in the shape, height, or width of the nasal bones can affect a person’s self-confidence. Especially in profile view, the angle and length of the nasal bones are among the most important factors defining a person’s facial character.

Beyond aesthetic concerns, the nasal bones also play a vital role in respiratory function. By shaping the upper part of the nasal cavity, they allow airflow to pass smoothly. Structural abnormalities of the nasal bones can lead to airway narrowing and respiratory problems.

The region called the nasal valve (the narrowest part just inside the nostrils) controls 50–60% of airflow during breathing. The position and shape of the nasal bones affect the geometry of this valve region and determine breathing quality. For example, collapses in the nasal bones after trauma may cause narrowing in the valve region and difficulty breathing.

In rhinoplasty surgery, we must balance both aesthetic and functional goals. An approach focused solely on appearance while neglecting breathing can negatively affect the patient’s quality of life. Therefore, in any intervention involving the nasal bones, maintaining the balance between “form and function” is essential.

What Are Common Conditions Affecting the Nasal Bone?

The most common condition affecting the nasal bones is undoubtedly traumatic fractures. As the most protruding and least protected part of the face, the nose is highly vulnerable to blows. Sports injuries, falls, traffic accidents, and physical violence are the main causes of nasal bone fractures.

Nasal bone problems encountered in clinical practice include:

1. Nasal Bone Fractures: The most common facial fracture. They may present as simple cracks, comminuted fractures, or depressed fractures. After a fracture, the shape of the nose may change, deviation may occur, or the nasal bone may collapse.
2. Congenital Deformities: These include asymmetry of the nasal bones, excessive width or narrowness present from birth. They may be seen together with craniofacial anomalies such as cleft lip and palate.
3. Nasal Bone Hypertrophy: In some patients, the nasal bones may be thicker and more prominent than normal. This condition is more common in individuals of Mediterranean and Middle Eastern origin and is also referred to as a “Roman nose.”
4. Nasal Bone Hypoplasia: This condition results from insufficient bone development and leads to a flat or depressed nasal appearance. It is frequently seen in genetic conditions such as Down syndrome.
5. Post-traumatic Deformities: Permanent deformities may occur after inadequately treated nasal bone fractures. These deformities can lead to both aesthetic concerns and breathing problems.
6. Inflammatory and Neoplastic Diseases: Although rare, inflammatory diseases such as Wegener’s granulomatosis or tumors may affect the nasal bones.

In daily practice, the most frequent situation I encounter is delayed presentation of nasal bone fractures. Patients often seek medical attention days after trauma, when nasal deformity begins to become permanent. However, intervention within the first 3–5 days in nasal bone fractures yields much better results.

How Do Nasal Bone Problems Affect Quality of Life?

Nasal bone problems can deeply affect patients’ lives both physically and psychologically. I frequently observe these effects in my daily practice.

From a physical perspective, nasal bone deformities may lead to:

• Breathing Difficulty: Narrowing in the nasal valve region makes breathing difficult. This becomes more noticeable during physical activity and reduces performance.
• Chronic Mouth Breathing: Patients who cannot breathe through the nose begin breathing through the mouth. This predisposes them to dry mouth, dental problems, and recurrent throat infections.
• Impaired Sleep Quality: Nasal obstruction increases the risk of snoring and sleep apnea. Poor sleep negatively affects daytime performance and overall quality of life.
• Reduced Sense of Smell and Taste: Disrupted nasal airflow may weaken the sense of smell, indirectly affecting taste.
• Sinusitis and Middle Ear Infections: Impaired nasal airflow negatively affects sinus drainage and Eustachian tube function, predisposing to recurrent infections.

Psychological and social effects include:

• Body Image and Self-Confidence Issues: Deformity of the nose, located at the center of the face, may negatively affect self-perception.
• Social Isolation: Patients with noticeable deformities, especially after trauma, may avoid social environments.
• Depression and Anxiety: Chronic respiratory problems and aesthetic concerns may lead to mental health issues.

One of my patients described posing in photographs for five years only from angles where his profile was not visible due to a nasal bone fracture from a sports accident. After reconstructive surgery, not only his nose but also his self-confidence was reshaped. Such experiences demonstrate that nasal bone problems have not only physical but also deep psychological effects.

These multifaceted effects on quality of life necessitate a holistic approach in treatment planning. Not only anatomical correction but also the patient’s expectations, psychological state, and lifestyle must be taken into consideration.

Conservative Treatment Approaches in Nasal Bone Problems

Not all nasal bone problems require surgical intervention. Conservative treatment options are available, especially for mild deformities, minimally displaced fractures, or patients unsuitable for surgery. These approaches aim both to relieve symptoms and prevent worsening of the condition.

1. Acute Trauma Management (First 48–72 Hours)

• Cold Application: Applying ice at 15–20 minute intervals immediately after trauma reduces swelling and pain. However, ice should be applied wrapped in a thin towel, not directly on the skin.
• Head Positioning: Keeping the head elevated increases venous return and helps reduce edema. I recommend that patients sleep with two pillows at night.
• Analgesics: Non-steroidal anti-inflammatory drugs (NSAIDs) may be used for pain control. Medications such as ibuprofen both reduce pain and provide anti-inflammatory effects.
• Nasal Decongestants: Short-term (3–5 days) topical decongestant sprays may be used to reduce intranasal swelling. However, prolonged use should be avoided due to the risk of rebound congestion.

2. Closed Reduction
   Although not considered full surgery, it is a minimally invasive intervention. Under local anesthesia, displaced nasal bones are repositioned using special instruments (Asch forceps, Walsham forceps). After the procedure, an external splint (plaster or thermoplastic material) is applied.

• Indications: Displaced nasal bone fractures, aesthetic deformity, nasal obstruction
• Optimal Timing: Within the first 3–10 days after trauma (it is important to wait for edema to decrease but intervene before bone healing begins)
• Advantages: Does not require general anesthesia, performed as a day procedure, minimally invasive
• Limitations: May be insufficient in complex fractures, does not correct septal deviation

3. External Splinting
   Devices that provide external support to maintain the position of the nasal bones. Usually applied after closed reduction but may sometimes be used alone.

• Types: Plaster splints, thermoplastic splints, prefabricated nasal splints
• Duration of Use: Usually 7–10 days
• Care: The splint should not get wet and should not be displaced

4. Internal Splinting
   Devices placed inside the nose to support the septum. Used in cases accompanied by septal deviation.

• Types: Silicone splints, tampons, airways
• Duration of Use: 24–72 hours (prolonged tampon use increases infection risk)

5. Physical Therapy Approaches
   May be helpful during the post-trauma healing process or in chronic nasal problems.

• Manual Therapy: Soft tissue mobilization, scar tissue massage
• Exercises: Strengthening the nasal dilator muscles
• Breathing Exercises: Techniques aimed at improving nasal breathing

6. Alternative and Complementary Approaches

• Acupuncture: May help reduce nasal congestion
• Aromatherapy: Essential oils such as eucalyptus and mint may increase nasal openness
• Nasal Irrigation: Washing the nose with saline solution helps clear mucus

In my clinical practice, I observe that the combination of closed reduction and splinting yields quite successful results, especially in mildly displaced fractures. However, it is important to provide realistic expectations to the patient. Closed reduction may not always provide a perfect cosmetic result, and in some cases, secondary rhinoplasty may be required.

Another important point is the urgent drainage requirement of post-traumatic nasal septum hematomas. This may be considered part of a conservative approach but should not be delayed. Undrained septal hematomas may lead to cartilage necrosis and eventually result in a “saddle nose” deformity.

When Is Nasal Bone Surgery Necessary and How Is It Performed?

Surgical treatment in nasal bone problems is considered when conservative approaches are insufficient or when complex deformities are present from the outset. The timing, technique, and extent of surgical intervention vary depending on the patient’s condition, expectations, and the surgeon’s experience.

Conditions Requiring Surgical Treatment:

1. Complex Nasal Bone Fractures: Comminuted fractures, open fractures, or fractures that cannot be corrected with closed reduction
2. Delayed Presentation of Fractures: Cases presenting 2–3 weeks after trauma when bone healing has begun
3. Fractures Accompanied by Septal Deviation: Conditions causing both aesthetic and functional problems
4. Post-traumatic Deformities: Permanent deformities after previous trauma or inadequate treatment
5. Congenital Nasal Bone Anomalies: Deformities present from birth
6. Tumors: Benign or malignant tumors affecting the nasal bone

Surgical Techniques:

Rhinoplasty (Nose Aesthetics)

• Open Rhinoplasty: A technique in which the entire nasal skeleton can be visualized by making a small incision on the columella
• Closed Rhinoplasty: A technique in which all incisions are made inside the nose, leaving no external scars
• Ultrasonic Rhinoplasty: A modern technique in which nasal bones are shaped more precisely using ultrasonic piezo devices

Septoplasty

• A procedure to correct deviation of the nasal septum
• Usually performed together with rhinoplasty (septorhinoplasty)
• Focuses on functional outcomes

Nasal Bone Osteotomies

• Lateral Osteotomy: Creating controlled fractures in the lateral walls of the nasal bone to reduce nasal width
• Medial Osteotomy: An incision made at the region where the nasal bones meet at the midline
• Intermediate Osteotomy: Additional cuts made between lateral and medial osteotomies to correct irregular fractures

Reconstructive Techniques

• Grafting: Reconstructing the nasal skeleton using cartilage, bone, or synthetic materials
• Flaps: Using flaps taken from local or distant tissues in cases of large tissue defects

Selection of Surgical Approach:

In choosing the surgical technique, I consider the following factors:

• Type and severity of the deformity
• Presence of functional problems
• Patient expectations
• Previous surgeries
• Patient’s age and general health status

For example, if there is only mild curvature of the nasal bones and the septum is straight, a simple lateral osteotomy may be sufficient. However, in a patient with complex post-traumatic deformity, septal deviation, and valve problems, septorhinoplasty with grafting using an open technique may be necessary.

Surgical Timing:

Timing after acute trauma is critical:

• Emergency Surgery: Immediate intervention in cases of open fractures, accompanying facial fractures, or septal hematoma
• Early Surgery: Closed reduction or simple surgical techniques may be applied within 3–10 days after trauma, once edema has decreased
• Late Surgery: Definitive rhinoplasty may be planned 3–6 months after trauma, when all edema has resolved and tissues have stabilized

In my clinical practice, especially in complex post-traumatic deformities, I prefer a “two-stage approach”: closed reduction and splinting in the acute phase, followed by definitive rhinoplasty 3–6 months later. This approach resolves urgent functional problems while providing the best chance of achieving optimal aesthetic results.

What Are Post-Treatment Care and Expectations After Nasal Bone Treatment?

The recovery process after treatment of nasal bone problems varies depending on the type of treatment applied, the patient’s age, and general health condition. Proper post-operative care directly affects treatment success and minimizes possible complications.

Post-Care After Closed Reduction:

First 24–48 Hours:

• Keeping the head elevated (at least 30 degrees)
• Intermittent cold application (15 minutes on, 15 minutes off)
• Avoiding heavy physical activity
• Regular use of prescribed pain medications

First Week:

• Protecting the external splint (do not wet or displace it)
• If nasal packing is present, breathing through the mouth due to difficulty breathing
• Keeping the mouth open when sneezing, avoiding nose blowing
• Avoiding wearing glasses (may put pressure on the splint)

After Splint Removal:

• Protecting the nasal region from direct trauma (for at least 6 weeks)
• Using sunscreen (reduces scar formation)
• Attending regular follow-up examinations

Post-Care After Rhinoplasty:

First 24 Hours:

• Continuous ice application (reduces swelling and bruising)
• Strict bed rest
• Avoiding activities that increase blood pressure
• Use of prescribed antibiotics and painkillers

First Week:

• Keeping the head elevated (with pillow support)
• Avoiding nose blowing, keeping the mouth open when sneezing
• Avoiding hot showers and baths (may increase edema)
• Minimizing talking and facial expressions
• Preferring a soft diet (reduces chewing movements)

2–4 Weeks:

• Gradual return to light activities
• Protection from the sun (prevents pigmentation changes)
• Avoiding wearing glasses (may put pressure on nasal bones)
• Saline sprays for cleaning the nostrils

1–3 Months:

• Avoiding contact sports
• Nasal massage (as recommended by the surgeon)
• Silicone tapes or gels (support scar healing)

Possible Complications and Management:

Early Complications:

• Bleeding: Mild oozing is normal, but active bleeding requires medical attention
• Infection: Antibiotic treatment may be necessary if fever, increasing pain, redness, or discharge occurs
• Hematoma: Especially septal hematoma must be urgently drained
• Excessive Edema: Usually resolves spontaneously; steroid treatment may be required

Late Complications:

• Persistent Deformity: Secondary surgery may be required
• Scar Formation: Silicone tapes, steroid injections, or laser treatment may be applied
• Nasal Obstruction: Functional revision surgery may be considered
• Olfactory Dysfunction: Usually temporary; if persistent, further evaluation is needed

Realistic Expectations:

I always emphasize realistic expectations to my patients after treatment:

• The Healing Process Is Individual: In some patients, edema and bruising may last longer
• Final Results Take Time: The final shape after nasal bone surgery appears within 6–12 months
• Improvement, Not Perfection, Is the Goal: Especially in post-trauma cases, it may not always be possible to return completely to the pre-trauma appearance
• Revision May Be Needed: In some cases, secondary interventions may be required for optimal results

The most important point I observe in my clinical experience is that patients must be patient during the recovery process. Especially after rhinoplasty, the nose may appear swollen and disproportionate in the first few weeks due to edema. During this period, providing psychological support and explaining that the process is normal is very important.

Another important point is not neglecting regular follow-up visits after treatment. Small problems detected early can be corrected with simple interventions, whereas delayed management may require more complex surgeries.
