Summary
Vocal process granulomas (VPGs) treatment combining surgery and botulinum toxin type A (BTA) injections shows higher cure rates. This approach offers an effective solution for patients unresponsive to conservative therapies.
Area of Science:
- Otolaryngology
- Laryngology
Background:
- Vocal process granulomas (VPGs) are benign lesions that can cause significant voice impairment.
- Conservative treatments, including acid suppression, vocal rest, and voice therapy, are often the first line of management for VPGs.
Purpose of the Study:
- To evaluate the efficacy of conservative treatments, microsurgical resection with suturing, and microsurgery combined with botulinum toxin type A (BTA) injections for VPGs.
Main Methods:
- A retrospective analysis of 168 VPG cases was conducted.
- Patients initially received conservative treatment; non-responders underwent microsurgical resection with suturing or microsurgery with BTA injections.
Main Results:
- Conservative treatments led to lesion disappearance in 41.3% and reduction in 10.7% of patients.
- Microsurgical resection achieved a 78.4% cure rate.
- The combination of microsurgery and BTA injections resulted in a 95.2% cure rate with low recurrence.
Conclusions:
- Combining laryngeal microsurgery with local botulinum toxin type A (BTA) injections significantly improves cure rates for vocal process granulomas (VPGs).
- This combined approach offers a highly effective treatment option for VPGs, particularly for cases refractory to conservative management.

2.5K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

01:23Chronic Pharyngitis
15.9K
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,...

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

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,...

3.6K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
