The laryngeal plain mirror is a fundamental tool in laryngology, aiding healthcare professionals in the examination of the larynx and vocal cords. This instrument consists of a small, angled mirror affixed to a handle, allowing for precise placement in the oral cavity to reflect light onto the laryngeal region. By directing light onto the mirror, clinicians can obtain a clear and magnified view of the larynx, aiding in the diagnosis and assessment of various laryngeal conditions. The laryngeal plain mirror plays a crucial role in indirect laryngoscopy, enabling healthcare providers to visualize the intricate structures of the throat and vocal apparatus during examinations, ultimately contributing to accurate diagnoses and effective treatment planning.
