To highlight the diagnosis and management of cough-predominant laryngeal hypersensitivity syndrome in a patient with unexplained chronic cough.
Key Findings:
Normal routine investigations can mask laryngeal hypersensitivity syndrome.
Flexible bronchoscopy is crucial for diagnosing exaggerated laryngeal sensitivity.
Symptoms include chronic cough, throat irritation, and globus sensation.
Interpretation:
Laryngeal hypersensitivity syndrome is often overlooked due to normal findings in standard tests, necessitating targeted evaluations for accurate diagnosis.
Limitations:
The study is based on a single patient case, limiting generalizability.
Lack of long-term follow-up data on management outcomes.
Conclusion:
This case emphasizes the need to consider laryngeal hypersensitivity syndrome in patients with chronic cough when standard investigations yield no results.
