Summary
Ultrasound (US) can image laryngeal neoplasms, especially advanced tumors, and detect spread to surrounding tissues. While not the primary method, US aids preoperative staging for laryngeal cancer.
Area of Science:
- Oncology
- Radiology
- Otolaryngology
Background:
- Sonography (US) is used for nodal staging in laryngeal neoplasms.
- The primary lesion of laryngeal neoplasms can sometimes be imaged via US.
Purpose of the Study:
- To investigate the capabilities of US in assessing the local stage of laryngeal neoplasms.
- To compare US findings with clinical and surgical staging.
Main Methods:
- Normal laryngeal US anatomy was assessed in 50 subjects.
- US was used to examine 17 patients with advanced laryngeal tumors.
- US findings were compared with clinical and surgical staging.
Main Results:
- Thyroid cartilage calcification, age-related, obstructs laryngeal US imaging.
- Laryngeal imaging was successful in 16 of 17 advanced tumor cases.
- US findings agreed with clinical staging in 14 cases; it identified understaging in 2 cases by detecting perilaryngeal spread.
Conclusions:
- US is not the primary method for laryngeal neoplasms staging.
- US can visualize advanced laryngeal tumors and their spread to anterolateral structures.
- US can contribute to preoperative staging and therapeutic approach selection in select cases.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

01:30Endoscopic 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...

01:26Endoscopic Studies II: Thoracocentesis
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
