Fiberoptic Rhinolaryngoscopy, often referred to as flexible rhinoscopy, is a quick, safe, in-office procedure used to perform a thorough diagnostic examination of the entire nasal cavity, throat, and larynx (voice box). By allowing our staff to directly see these hard-to-reach internal structures, we’re able to use this advanced diagnostic tool to hlep identify the root cause of your persistent nasal, sinus, and/or vocal symptoms.
When Is Fiberoptic Rhinolaryngoscopy Needed?
Allergists and otolaryngologists frequently utilize flexible rhinoscopy to evaluate chronic or unexplained upper respiratory symptoms. Your doctor may recommend this procedure if you are experiencing:
- Chronic nasal obstruction or congestion
- Recurrent or persistent sinusitis (sinus infections)
- Unexplained nosebleeds (epistaxis)
- Reduced or lost sense of smell (anosmia)
- Persistent rhinitis symptoms that do not respond to standard allergy treatments
- Lingering cough, hoarseness, or post-nasal drip
- Symptoms of vocal cord dysfunction (VCD/PVFM)
What Conditions Can Flexible Rhinoscopy Detect?
By using a thin, flexible endoscope equipped with light and camera technology, we can spot and diagnose the problem in real time.
Commonly identified findings include issues with the nasal structure (such as nasal polyps, a deviated septum, enlarged or abnormal turbinates, and localized swelling) or laryngeal irritation caused by acid reflux (GERD), vocal cord inflammation, and abnormal vocal cord movements typical of VCD.
