What is the purpose of a nasal speculum?

The primary purpose of a nasal speculum is to allow for a detailed examination of the inside of the nose. By utilizing a nasal speculum, healthcare providers can gently expand the nasal passages, which enhances visibility and access to the nasal mucosa and structures. This examination is crucial for diagnosing various conditions affecting the nasal cavity, such as polyps, tumors, or signs of infection.

While expanding nostrils for better airflow can aid in visualization, the speculum is specifically designed to facilitate a thorough visual assessment, not just to improve airflow. Extraction of mucus is typically achieved with different tools specifically designed for that purpose, rather than a nasal speculum. Additionally, while a nasal speculum can assist in the preliminary examination of sinus-related issues, diagnosing sinus infections typically requires further investigation, including imaging or additional clinical information beyond what can be determined solely by visual examination of the nasal cavity. Thus, the most accurate labeling of the nasal speculum's primary function aligns with facilitating an internal examination of the nasal structures.
