How does TB affect the larynx?
Although it can be treated successfully, tuberculosis of the larynx may cause irreversible fibrotic changes in the lamina propria of the vocal fold involved and may cause a permanent breathy voice. This condition is very important in vocal professionals.
What is tuberculosis of the larynx?
Tuberculosis of the larynx is a rare form of tuberculosis. Patients usually present with hoarseness or dysphagia and other nonspecific constitutional symptoms like fever or localized pain. In this study, we present a case of primary vocal cord lesion with tuberculosis.
What are the salient features of pulmonary tuberculosis?
Primary pulmonary TB should be distinguished from postprimary pulmonary TB, which is the most frequent TB manifestation in adults. The classic clinical features of pulmonary TB include chronic cough, sputum production, appetite loss, weight loss, fever, night sweats, and hemoptysis (Lawn and Zumla 2011).
What are the manifestations of TB?
Coughing for three or more weeks. Coughing up blood or mucus. Chest pain, or pain with breathing or coughing. Unintentional weight loss.
Does TB affect your voice?
TB infection can result in multiple atypical presentations of disease, including hoarseness of voice secondary to vocal cord paralysis. This is a rare but important presentation for community clinician’s to consider, especially in populations where TB is epidemiologically thought to be prevalent.
Is hoarseness a symptom of TB?
The most common symptom associated with laryngeal tuberculosis is hoarseness that may be accompanied by odynophagia, dysphagia, cough, otalgia, and stridor.
Does TB cause laryngitis?
Laryngeal tuberculosis, or tuberculous laryngitis, involves infection of the larynx by Mycobacterium tuberculosis, mostly spread through the airway from the primary site, pulmonary tuberculosis. Hoarseness is one of the most common symptoms.
How is laryngeal TB spread?
Laryngeal tuberculosis is rare, with an incidence of 1%. The spread of infection is direct from a bronchus or hematogenous spread. The most common symptom associated with laryngeal tuberculosis is hoarseness that may be accompanied by odynophagia, dysphagia, cough, otalgia, and stridor.
What is lupus of larynx?
Laryngeal involvement in systemic lupus erythematosus (SLE) can range from mild ulcerations, vocal cord paralysis, and edema to necrotizing vasculitis with airway obstruction.
Is laryngeal TB infectious?
Although laryngeal tuberculosis only accounts for ∼1% of all tuberculosis cases, laryngeal tuberculosis is terrific contagious. Laryngeal tuberculosis has been considered to be the result of extra-pulmonary manifestations, and has often been associated with pulmonary tuberculosis.
How is laryngeal tuberculosis distinguished from foreign body?
Laryngeal tuberculosis must be distinguished from foreign body–type granulomatous inflammation in the larynx, which can be seen after Teflon injection or with laryngeal amyloidosis. Skye Zeller, Elie M. Ferneini, in Head, Neck, and Orofacial Infections, 2016
Is the larynx a part of the trachea?
The larynx (latin: larynx) is a flexible passageway for air between the oropharynx and the trachea, which plays an essential role in sound production and protects the lower airway against food inspiration. The larynx is a part of the upper respiratory tract.
When does laryngeal TB become a terminal event?
Before the advent of effective chemotherapy for TB, laryngeal TB was considered a terminal event during the progression of pulmonary TB, developing soon before death, and possibly occurring in over 50% of patients. In the era of effective chemotherapy, laryngeal TB has become rare (< 1% of TB cases).
What are the medical conditions that affect the larynx?
This part of the body can be subject to a number of significant medical conditions, including bacterial infection (laryngitis), laryngeal cancer, and vocal fold paralysis (VFP), which can seriously compromise function. The larynx is a complex band of cartilage, ligament, and muscle as well as a mucous membrane.
