Anatomy of the Nasal Septum

The nasal septum serves as a crucial anatomical structure within the nasal cavity, providing structural support and partitioning the nasal passages into right and left sides. Composed of cartilage, bone, and a mucous membrane lining, the nasal septum plays a vital role in nasal airflow, olfaction, and overall respiratory function.

Cartilaginous Framework:

At its anterior (front) portion, the nasal septum is primarily composed of hyaline cartilage. This cartilaginous framework provides flexibility and support to the nasal bridge and nasal tip, contributing to the external contour of the nose.

Bony Component:

Posteriorly (towards the back), the nasal septum is reinforced by the perpendicular plate of the ethmoid bone superiorly and the vomer bone inferiorly. These bony structures provide stability and rigidity to the nasal septum, anchoring it securely within the nasal cavity.

Mucous Membrane Lining:

Covering the internal surface of the nasal septum is a specialized mucous membrane known as the respiratory epithelium. This mucosal lining contains numerous ciliated cells, goblet cells, and mucus-secreting glands, which work together to humidify, filter, and cleanse the inspired air as it passes through the nasal passages.

Blood Supply and Nerve Innervation:

The nasal septum receives its blood supply from branches of the internal maxillary artery, including the sphenopalatine artery and the anterior ethmoidal artery. Innervation of the nasal septum is provided by branches of the trigeminal nerve (cranial nerve V), including the anterior ethmoidal nerve, posterior ethmoidal nerve, and nasopalatine nerve.

Structural Variations and Deviations:

While the nasal septum is typically straight and midline in structure, variations and deviations can occur, leading to septal deviations. These deviations may result from developmental abnormalities, trauma, or inflammatory conditions, potentially impacting nasal airflow, sinus drainage, and overall nasal function.

Understanding Deviated Nasal Septum

A deviated nasal septum is a common condition where the nasal septum, the thin wall of cartilage and bone that divides the nasal passages into two, is displaced or deviated from its normal position. This deviation can vary in severity, ranging from mild asymmetry to significant obstruction of one or both nasal passages.

Causes

  • Developmental
  • Abnormalities
  • Trauma
  • Aging
  • Congenital Conditions
  • Environmental Factors

Symptoms

  • Nasal Congestion
  • Difficulty Breathing
  • Recurrent Sinus
  • Infections
  • Headaches
  • Nosebleeds
  • Sleep Disturbances

Impact of Deviated Nasal Septum on Nasal Breathing and Airflow

To comprehend the impact of a deviated nasal septum on nasal breathing and airflow, it’s crucial to grasp the normal nasal anatomy and airflow dynamics. The nasal cavity comprises two passages divided by the nasal septum, through which airflow passes during inhalation and exhalation. Ideally, nasal airflow should be smooth and unimpeded, facilitating efficient air exchange and optimal filtration of airborne particles.

When the nasal septum is deviated or displaced from its usual position, it can obstruct one or both nasal passages, disrupting airflow and causing various symptoms. The severity of airflow obstruction and symptoms experienced by individuals depend on the degree of septal deviation.

Common effects of septal deviation on nasal breathing and airflow include:

  • Nasal Congestion
  • Airflow Resistance
  • Uneven Air Distribution
  • Sinus Issues
  • Sleep Disturbances

Effects on Oral Health and Dental Functioning

Malocclusion: A deviated nasal septum can alter the alignment of the upper and lower dental arches, resulting in malocclusion or misalignment of the teeth. This misalignment may manifest as crowding, spacing, crossbite, or overbite/underbite, depending on the extent and direction of septal deviation. Malocclusion can affect chewing function, speech clarity, and overall oral health.

Temporomandibular Joint (TMJ) Disorders: Septal deviation may contribute to the development or exacerbation of temporomandibular joint disorders (TMDs) by altering the biomechanics of the jaw and affecting occlusal stability. Patients with a deviated nasal septum may experience symptoms such as jaw pain, clicking or popping noises, limited mouth opening, and muscle tenderness, indicating underlying TMJ dysfunction.

Mouth Breathing: Nasal obstruction due to septal deviation can lead to chronic mouth breathing, especially during sleep or periods of nasal congestion. Mouth breathing bypasses the natural filtration and humidification mechanisms of the nasal passages, resulting in dry mouth, increased susceptibility to oral infections, halitosis (bad breath), and dental caries (cavities). Prolonged mouth breathing can also contribute to changes in facial growth and development, particularly in children.

Gingival and Periodontal Health: Chronic mouth breathing associated with a deviated nasal septum can contribute to gingival inflammation (gingivitis) and periodontal disease (periodontitis) due to decreased saliva flow, altered oral pH, and reduced antimicrobial activity. Patients may exhibit signs of gum inflammation, bleeding gums, and periodontal pocketing, requiring comprehensive periodontal therapy to manage oral health issues effectively.

Dental Sleep Medicine: Septal deviation and associated nasal obstruction can predispose individuals to sleep-disordered breathing (SDB) conditions such as obstructive sleep apnea (OSA) or upper airway resistance syndrome (UARS). These conditions are characterized by recurrent episodes of partial or complete upper airway collapse during sleep, leading to disrupted breathing patterns, oxygen desaturation, and fragmented sleep architecture. Dental professionals play a crucial role in recognizing signs of SDB, collaborating with sleep physicians for diagnosis and implementing oral appliance therapy as part of comprehensive treatment approaches.

Oral Hygiene Challenges and Strategies for Individuals with Deviated Nasal Septum

  • Mouth Breathing: Nasal obstruction resulting from septal deviation can lead to chronic mouth breathing, especially during sleep or periods of nasal congestion. Mouth breathing bypasses the natural filtration and humidification mechanisms of the nasal passages, resulting in decreased saliva flow, dry mouth, and increased susceptibility to oral infections such as gingivitis and dental caries.
  • Reduced Salivary Flow: Chronic mouth breathing and nasal congestion can contribute to decreased salivary flow, leading to xerostomia or dry mouth syndrome. Reduced saliva production diminishes the mouth’s natural ability to neutralize acids, remineralize enamel, and wash away food debris and bacteria, increasing the risk of dental erosion, tooth decay, and gum disease.
  • Oral Microbial Imbalance: Alterations in oral pH and microbial composition may occur in individuals with deviated nasal septum and associated mouth breathing habits. Imbalances in oral microbiota can promote the growth of pathogenic bacteria, fungi, and yeast, leading to conditions such as oral candidiasis (thrush), halitosis (bad breath), and oral infections.
  • Dental Malocclusion: Septal deviation can contribute to malocclusion or misalignment of the teeth and jaws, affecting occlusal stability, masticatory function, and oral hygiene access. Malocclusion may predispose individuals to dental crowding, spacing, crossbite, or overbite/underbite, making it challenging to clean between teeth and maintain proper oral hygiene practices.
  • Nasal Breathing Optimization: Encourage individuals with deviated nasal septum to optimize nasal breathing patterns and reduce reliance on mouth breathing through functional breathing exercises, nasal decongestants, or nasal irrigation techniques. Improved nasal airflow promotes saliva production, enhances oral mucosal hydration, and supports oral microbial balance.
  • Oral Hygiene Education: Provide comprehensive oral hygiene education and personalized oral care instructions to individuals with deviated nasal septum, emphasizing the importance of regular brushing, flossing, and tongue cleaning. Educate patients on the potential oral health consequences of mouth breathing and the importance of addressing nasal congestion to promote nasal breathing and oral health.
  • Salivary Stimulation: Recommend salivary stimulation strategies such as sugar-free gum chewing, lozenges, or oral moisturizing products to alleviate dry mouth symptoms and enhance saliva flow. Adequate saliva production helps buffer acids, protect tooth enamel, and maintain oral mucosal integrity, reducing the risk of dental caries and periodontal disease.
  • Regular Dental Check-ups: Schedule regular dental check-ups and professional cleanings for individuals with deviated nasal septum to monitor oral health status, identify early signs of dental issues, and address any concerns promptly. Routine dental examinations allow for early detection and intervention, preventing the progression of oral health problems and optimizing treatment outcomes.
  • Collaboration with Healthcare Providers: Collaborate with otolaryngologists, allergists, or respiratory specialists to address underlying nasal obstruction or breathing difficulties contributing to oral hygiene challenges. Multidisciplinary care coordination ensures comprehensive evaluation, personalized treatment planning, and holistic management of nasal and oral health concerns.
