Nasal Deformity

Otolaryngology

Nasal deformity refers to abnormal changes in the appearance or structure of the nose, which may involve irregular variations in the shape or size of the nasal bridge, wings, nasal tip, or nostrils. Various factors, including congenital factors, trauma, complications after surgery, nasal infections, or other nasal conditions can cause nasal deformities. The severity of the deformity can range from mild to severe, with some affecting only aesthetic appearance, while others may lead to difficulty breathing or other functional impairments.

Symptoms

Symptoms of nasal deformity can vary depending on the type and severity of the deformity, affecting both appearance and function. Here are some common symptoms:
 

Changes in appearance

  • Abnormal nasal shape
  • Curved or deviated nasal bridge
  • Flattened, pointed, or excessively prominent nasal tip
  • Uneven or abnormally shaped nostrils
  • Asymmetry of the nose, with significant differences between the two sides

 

Functional issues

  • Difficulty breathing: Deviated nasal septum or other structural abnormalities may lead to blockage of one or both nasal passages, affecting normal breathing.
  • Nasal congestion or chronic stuffiness: Structural abnormalities may cause persistent feelings of nasal congestion, affecting breathing and sleep quality, leading to snoring or sleep apnoea.
  • Frequent nasal infections: Nasal deformities may disrupt proper drainage, increasing the risk of diseases such as sinusitis.
     

Other symptoms 

  • Headaches: In some cases, structural issues in the nose, especially those related to sinus problems, may lead to recurrent headaches.
  • Loss of smell: In severe cases, nasal deformities may affect the sense of smell.

Causes

The causes of nasal deformity can generally be categorized into congenital and acquired factors:

Congenital Causes

Genetic factorsCertain genetic conditions or syndromes may be associated with nasal deformities, such as cleft lip and palate, congenital nasal septal deviation, etc.
Embryonic developmental abnormalitiesDuring embryonic development, nasal structures may fail to form properly due to genetic issues or maternal environmental influences (such as exposure to certain medications or environmental toxins).


Acquired Causes

TraumaCommon causes of acquired nasal deformities include nasal bone fractures or soft tissue injuries resulting from impact, accidents, or sports injuries.
Post-surgical sequelaeNasal surgery, especially rhinoplasty, may result in unnatural nasal shapes or functional impairments due to surgical technique or issues during the healing process.
IllnessCertain diseases, such as skin cancer, lupus erythematosus, etc., may affect the nose, leading to tissue damage or deformity. 
Chronic infections like rhinitis or sinusitis may also cause structural changes.
Environmental factorsLong-term exposure to certain chemicals or environmental irritants may cause degradation or damage to nasal tissues.
LifestyleSmoking may exacerbate tissue degradation, negatively impacting overall nasal health. With age, changes in nasal structure may occur due to the loss of collagen and elastic fibres during the natural ageing process.
AgingChanges in nasal structure may occur due to the loss of collagen and elastic fibers during the natural aging process.

Effects

The impact of nasal deformity can broadly be categorized into two main areas: functional effects and aesthetic-psychological effects.

 

Functional Effects

  • Difficulty breathing: Deviated septum or other structural issues in the nose may partially or entirely block the nasal passage, affecting normal breathing. It is particularly evident during physical activity or nighttime sleep and may result in snoring or sleep apnoea.
  • Recurrent nasal infections: Deformities may hinder normal drainage of the nasal cavity, making the sinuses more prone to disease, such as sinusitis.
  • Impaired olfactory function: Abnormal nasal structure may affect the olfactory nerves, leading to a decrease in the sense of smell.
  • Changes in speech: Nasal deformities may affect the nasal aspect of speech, resulting in a nasal tone.

 

Aesthetic and Psychological Effects

  • Self-image issues: The nose, centrally located on the face, is a prominent facial feature. Deformities may negatively impact an individual's self-image and confidence, particularly in adolescents and adults sensitive to appearance.
  • Social distress: People may fear social rejection or ridicule due to appearance, leading to social anxiety and isolation.
  • Psychological stress: Dissatisfaction related to appearance may lead to long-term psychological stress and anxiety, requiring professional psychological support and counselling.

Diagnosis & Treatments

Diagnosis and treatment of nasal deformities require a comprehensive consideration of the patient's type, severity, and specific needs. Here are common diagnostic and treatment steps:

 

Diagnosis Methods

Medical history assessment

The doctor will inquire about the patient's health condition, including whether the deformity is congenital or acquired, and any symptoms related to the deformity such as difficulty breathing, nasal congestion, or recurrent infections.

Clinical examination

Detailed examination of the nasal appearance to assess the type and extent of the deformity, as well as examination of the nasal septum, nasal cavity, and surrounding structures.

Imaging tests:

Including X-rays, CT scans, or MRIs, which help evaluate the detailed condition of the nasal structures, especially when considering corrective surgery.

Functional tests

May include respiratory flow tests and olfactory tests to assess the impact of nasal deformity on function.

 



Treatment Methods

Surgical correction

Surgical correction: Rhinoplasty (nose reshaping surgery) or septoplasty (septum correction surgery) are standard methods for treating structural nasal deformities. These surgeries can improve the appearance of the nose and restore nasal airflow.

For severe deformities or functional impairments, complex reconstructive surgery may be necessary.

Non-surgical treatmentsFor mild deformities or patients unwilling to undergo surgery, nasal splints or other orthotic devices may help correct the deformity.
Medication therapyAnti-inflammatory drugs or nasal sprays may be used to treat symptoms such as nasal congestion caused by deformity.
Supportive therapy
  • Physical therapy, such as breathing exercises, can help patients better manage respiratory issues.
  • Psychological support is essential for patients who feel insecure or anxious due to appearance issues, providing psychological counselling and support.

For patients with nasal deformities, the treatment plan should be personalized based on the patient's specific symptoms, type of deformity, and expectations. Treatment aims to improve or restore function, enhance quality of life, and address aesthetic concerns.

Head and Neck Cancer

Clinical OncologyOtolaryngologyGeneral Surgery
Head and neck cancer is a collective term for cancers that occur in various upper respiratory tract tissues. Depending on the site of occurrence, it can be divided into oral cancer, nasopharyngeal cancer, oropharyngeal cancer, hypopharyngeal cancer, and laryngeal cancer. The most common tumour type in head and neck cancer is squamous cell carcinoma, which originates from squamous cells on the mucosal surface of the head and neck. According to medical research, some head and neck cancers are associated with HPV (human papillomavirus).

Nasopharyngeal Cancer

Clinical OncologyOtolaryngologyGeneral Surgery
Nasopharyngeal cancer is one of the top ten cancers in Hong Kong that cannot be ignored. There are 600 to 800 cases of nasopharyngeal cancer in the city every year. Unlike many other cancers, nasopharyngeal cancer tends to occur at a relatively early age, with the peak incidence between 40 and 60 years old, considered the prime of one's life. The incidence rate is almost three times higher in males than in females. Compared to Western countries, nasopharyngeal cancer is more commonly found in Southern China.

Oral Cancer

Clinical OncologyOtolaryngology
The "oral" region comprises multiple sites, including the lips, tongue, floor of the mouth, hard palate, and gums, as well as the oral mucosa, buccal mucosa, and salivary glands. Any malignant tumour growing in these locations is collectively referred to as oral cancer, which is also one of the types of head and neck cancer.
