Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Summary

Active anterior rhinomanometry (AARNM) and nasal endoscopy (NE) correlate expiratory airflow with inferior nasal obstructions. However, this correlation is not predictive in narrow nasal vestibules.

Area of Science:

Otolaryngology
Rhinology

Background:

Nasal permeability is influenced by functional and anatomical factors.
Active anterior rhinomanometry (AARNM) quantifies these parameters.
Nasal endoscopy (NE) provides visual assessment of nasal structures.

Purpose of the Study:

To compare nasal alterations visualized via NE with nasal airflow parameters obtained from AARNM.
To evaluate the diagnostic validity of comparing NE findings with AARNM measurements.

Main Methods:

Prospective observational study involving 45 patients with nasal obstruction and septal deviation.
Patients underwent both AARNM and NE examinations.
Nasal deviations were categorized into anterosuperior and anteroinferior quadrants.

Main Results:

Global comparison of AARNM and NE yielded a sensitivity of 74.6% and a specificity of 60.5%.
A reduced expiratory airflow phase correlated with inferior obstructions identified by NE.

Conclusions:

Inferior nasal obstructions visualized by NE are associated with reduced expiratory airflow.
This correlation is not a reliable predictor in cases of a narrow nasal vestibule.
