Summary
Granulomatosis with Polyangiitis (GPA) can cause rare laryngeal stenosis. Early diagnosis and intervention are crucial for better outcomes in this ANCA-associated vasculitis.
Area of Science:
- Rheumatology
- Otolaryngology
- Pathology
Background:
- Granulomatosis with Polyangiitis (GPA), or Wegener's, is an ANCA-associated vasculitis affecting small vessels.
- Laryngeal involvement, specifically subglottic stenosis, is a rare but severe complication of GPA.
Observation:
- A case of a woman in her 70s with recurrent glottic-subglottic stenosis after laser microsurgery.
- Histological findings included giant cells and inflammation suggestive of vasculitis, with positive Anti-Neutrophil Cytoplasmic Antibodies (ANCA).
Findings:
- Diagnosis of GPA was confirmed despite atypical presentation, highlighting delayed diagnosis due to non-specific inflammation.
- Surgical intervention provided short-term relief, but relapse occurred, necessitating further management.
Implications:
- This case emphasizes the importance of considering GPA in patients with unexplained laryngeal stenosis.
- Early diagnosis and multidisciplinary management are vital for improving patient prognosis in GPA-related airway complications.

01:21Larynx
1.1K
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,...

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:23Chronic Pharyngitis
705
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
