Nasal spectum devision in humans

1. Nasal Septum Deviation Shane Stanley Seu - 35781

2. Introduction The nasal septum divides the nasal cavity into two nostrils. A deviation occurs when the septum is displaced from the midline. Common condition — up to 80% of people have some form of deviation. Only symptomatic cases usually require treatment.

3. Anatomy of the Nasal Septum Components: Anterior: quadrilateral cartilage Posterior: vomer and perpendicular plate of the ethmoid Supportive Structures: Nasal bones, upper lateral cartilages Vascular Supply: Kiesselbach's plexus (Little’s area) Image: Diagram showing nasal septum anatomy

4. Causes of Septal Deviation Congenital: Developmental asymmetry, Intrauterine or birth trauma Traumatic: Sports injuries, Accidents or fights. Iatrogenic: Surgical trauma during nasal or sinus surgery

5. Classification of Deviation C-shaped : one side compressed S-shaped : deviation to both sides Spur : sharp angulated projection Anterior vs Posterior deviation Thickening of the spetum

7. Clinical Features Nasal obstruction (unilateral or bilateral) Snoring and mouth breathing Recurrent sinus infections Epistaxis (nosebleeds) Headaches or facial pressure Postnasal drip

8. Diagnosis History : breathing difficulty, snoring, trauma, nasal obstruction Examination : Anterior rhinoscopy, Nasal endoscopy for detailed view Imaging : CT scan of paranasal sinuses Helpful in surgical planning

9. Differential Diagnosis Inferior turbinate hypertrophy Nasal polyps Foreign body (especially in children) Chronic allergic or non-allergic rhinitis Nasal valve collapse

10. Management – Non-Surgical Used in mild or asymptomatic cases. Pharmacologic options: Intranasal corticosteroids Oral antihistamines (if allergic component) Saline sprays and decongestants (short-term only) Symptom management, not structural correction

11. Management – Surgical Septoplasty : Gold standard for symptomatic deviation Realigns or removes deviated portion May be combined with: Turbinoplasty , Functional Endoscopic Sinus Surgery (FESS) Complications: Bleeding, septal perforation, hematoma, persistent symptoms

12. Prognosis and Outcomes High success rate with septoplasty Significant improvement in airflow and quality of life Minor risk of recurrence or residual deviation Post-op care: nasal saline irrigation, follow-up visits

13. Case Example Patient: 28-year-old male with history of nasal trauma Symptoms: unilateral obstruction, snoring Treatment: CT showed S-shaped deviation, underwent septoplasty Outcome: resolution of symptoms post-surgery Include before-and-after endoscopy/CT images if possible

14. Conclusion Nasal septum deviation is common, but only treated if symptomatic Proper diagnosis essential to exclude other causes Septoplasty is a safe, effective procedure Long-term outcomes are generally excellent
