Chronic Pharyngitis

Chronic Pharyngitis

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,...

Anatomy of Respiratory System I: Upper Respiratory Tract

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Summary

Cricopharyngeal dysfunction in an 80-year-old man caused significant piriform sinus expansion and dysphagia. A subsequent cricopharyngeal myotomy successfully resolved his swallowing difficulties.

Area of Science:

Otolaryngology
Gastroenterology
Neurology

Background:

Cricopharyngeal dysfunction can lead to significant swallowing difficulties.
Piriform sinus expansion is an uncommon sequela of cricopharyngeal dysfunction.

Observation:

An 80-year-old male presented with a 3-year history of dysphagia.
Electromyography revealed cricopharyngeal chalasis (dysfunction) with associated piriform sinus expansion.
Initial bougie widening provided minimal relief.

Findings:

Cricopharyngeal myotomy, performed after a 6-month recovery period, completely resolved the patient's dysphagia.
Histopathological findings suggested cricopharyngeal myopathy as the underlying cause.

Implications:

Cricopharyngeal myotomy is an effective treatment for dysphagia secondary to cricopharyngeal dysfunction and associated piriform sinus expansion.
This case highlights the importance of considering cricopharyngeal myopathy in patients with unexplained dysphagia and piriform sinus abnormalities.
