Is fiberoptic nasopharyngoscopy painful?
Generally, whether a fiberoptic nasopharyngoscopy is painful depends on individual tolerance and the specifics of the procedure. When patients have good tolerance and the procedure is performed gently, it is usually not painful—most experience only mild discomfort. However, noticeable discomfort may occur if the mucosa is sensitive or the patient does not cooperate well. A detailed analysis is as follows:

If the patient’s nasal and pharyngeal mucosa are healthy, without significant inflammation or narrowing, and the physician performs the procedure skillfully and gently, local anesthetic will be applied beforehand to shrink the mucosa and reduce irritation. In such cases, the examination proceeds smoothly. Most individuals feel only a slight foreign body sensation or mild pressure in the nasal cavity. By maintaining deep breathing and staying relaxed, the procedure can be completed within minutes without causing significant pain.
However, if the patient has underlying conditions such as rhinitis or sinusitis, with congested and swollen mucosa, or an overly sensitive pharyngeal reflex, discomfort such as nasal pain, nausea, or dry retching may occur during the examination. Some individuals who are excessively anxious may tense their muscles, increasing friction as the instrument passes through, thereby intensifying discomfort. Nevertheless, these sensations are typically temporary and quickly subside once the procedure ends.
Prior to the examination, nasal secretions should be cleared, and high-collared clothing should be avoided to prevent interference with the procedure. It is important to stay emotionally calm and follow the doctor's instructions regarding breathing and head positioning.
