Relationship between laryngoceles and laryngeal carcinomas

|April 1, 1978
Summary
Laryngoceles are rare in normal larynges but frequently found with laryngeal cancer. Cancer appears to cause laryngoceles, sometimes developing within them, leading to potential misdiagnosis.
Area of Science:
- Otolaryngology
- Surgical Pathology
Background:
- X-ray imaging is unreliable for detecting laryngoceles.
- Laryngoceles are air-filled sacs within the larynx.
Purpose of the Study:
- To determine the frequency of laryngoceles in surgical specimens.
- To investigate the relationship between laryngoceles and laryngeal carcinomas.
Main Methods:
- Systematic measurement of ventricular depth in surgical specimens.
- Microscopic examination of laryngeal cancer specimens for associated laryngoceles.
Main Results:
- Laryngoceles occurred in approximately 2% of normal larynges.
- Laryngoceles were present in about 18% of laryngeal cancer specimens.
- Microscopic analysis revealed a close relationship between tumors and diverticuli in half of the cancer cases.
Conclusions:
- Laryngeal cancer plays a significant role in the development of laryngoceles.
- Carcinomas can arise within laryngoceles, potentially leading to misdiagnosis as ulcerated tumors.
- Understanding this association is crucial for accurate diagnosis and treatment of laryngeal conditions.
