Nasopharyngoscopy
nasopharyngeal surgical procedure
A nasopharyngoscopy is a surgical procedure performed to examine the nose and throat. It is performed using a fiberoptic instrument called a flexible fiberoptic nasopharyngoscope, that is inserted through the nose in order to examine both it, and the back of the throat. It is typically used to identify a variety of conditions including nasal septal deviation, polyps, and edema, and the causes of conditions including nosebleeds and sore throat. This procedure can be combined with the intentional application of intrathoracic pressure to perform a procedure known as Müller's maneuver. It is often used to examine cases of obstructive sleep apnea, and is often favorable to other procedures as it does not require exposure to radiation, can be performed while the patient is sitting or in the supine position, can both be performed while the patient is asleep or awake, and is inexpensive. However, it is an invasive procedure, which may make it unfavorable to some. It is also often used to evaluate children with stridor. In other cases, it can be used to evaluate and diagnose cases of nasopharyngeal cancer, often in addition to a biopsy.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Nasopharyngoscopy”, the useful work is to connect “nasopharyngeal surgical procedure” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 20, 2025. The linked authority identifier is Q104518940. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
