Summary
Laryngeal schwannoma, a rare benign tumor, presents unique diagnostic and surgical challenges. This study highlights MRI's role and successful surgical outcomes for these rare laryngeal tumors.
Area of Science:
- Laryngology
- Oncology
- Pathology
Context:
- Laryngeal schwannoma is a rare benign tumor originating from Schwann cells.
- These tumors most commonly occur in the supraglottic region and can affect any age group.
- Distinguishing laryngeal schwannomas from neurofibromas is crucial for appropriate management.
Purpose:
- To report two distinct cases of laryngeal schwannoma in an infant and a young adult.
- To emphasize the diagnostic utility of Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans.
- To discuss the optimal surgical treatment and potential associations of laryngeal schwannomas.
Summary:
- Two cases of laryngeal schwannoma are presented: an infant with stridor and a young adult with dysphonia.
- Nasofibroscopy revealed submucosal masses on the false vocal cord in both patients.
- Imaging (CT and MRI) demonstrated well-defined lesions, confirmed as schwannomas by biopsy, followed by successful surgical excision.
Impact:
- This study underscores the importance of advanced imaging techniques like MRI for diagnosing laryngeal schwannoma.
- It reinforces conservative surgical intervention as the primary treatment modality.
- Understanding the presentation and diagnosis of laryngeal schwannoma aids in timely and effective patient management.

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...

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
