Clinical Presentation, Diagnostic Evaluation, and Treatment Approaches for Deviated Nasal Septum (DNS)

Introduction

The nasal septum is the partition that divides the nasal cavity into two halves. A deviated nasal septum (DNS) occurs when this partition is displaced, leading to symptoms such as nasal obstruction, breathing difficulties, and sinus infections. This blog explores the causes, symptoms, and treatment options, including surgical interventions such as septoplasty.

Clinical Presentation

Symptoms

• Unilateral or bilateral nasal obstruction
• Frequent sinus infections
• Difficulty in breathing
• Snoring and sleep apnea
• Nasal congestion and postnasal drip

Diagnostic Evaluation

Physical Examination

ENT specialists perform a nasal examination using an otoscope or nasal endoscope to assess septal deviation and airway obstruction.

Imaging Studies

CT scans or X-rays may be used in complex cases to determine the extent of septal deviation and associated conditions such as sinusitis.

Treatment Approaches

Non-Surgical Management

For mild cases, management includes nasal decongestants, antihistamines, and nasal sprays to relieve symptoms.

Surgical Interventions

Septoplasty

Septoplasty is the definitive treatment for DNS, aiming to straighten the nasal septum to improve airflow and alleviate symptoms.

Additional Corrective Procedures

Other procedures such as turbinate reduction or rhinoplasty may be performed alongside septoplasty for improved functional and aesthetic outcomes.

Conclusion

DNS is a common ENT condition that can impact breathing and quality of life. While medical management can help mild cases, surgical intervention remains the most effective treatment for severe septal deviations.
