Objective:
Laryngeal cancer is the second most prevalent head and neck malignancy in the USA. With recent advances in technology, this procedure is increasingly performed under local anaesthesia. This study aimed to identify the efficacy, safety and cost-effectiveness of laryngeal biopsy in out-patients by conducting a systematic review.
Method:
A literature search was conducted using PubMed, Medline, Google Scholar and Embase over a 20-year period. Inclusion criteria were: studies performed on out-patient diagnostic biopsy procedures of the larynx. Exclusion criteria included all therapeutic procedures. The outcome measures were sensitivity and specificity, complication rate and cost-savings.
Results:
Thirty-five studies were included in the analysis. The sensitivity and specificity varied from 60 to 100 per cent with a low complication rate and cost savings.
Conclusion:
Office-based laryngeal biopsies are increasingly used in the diagnosis of laryngeal cancers, resulting in earlier diagnosis and commencement of treatment. The barrier to undertaking this procedure is low sensitivity.

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,...

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...
