Summary
Patients with chronic cough often have swallowing difficulties and aspiration risks, even without subjective complaints. Swallowing maneuvers, like multiple swallowing, can be effective in managing these risks.
Area of Science:
- Otorhinolaryngology
- Pulmonology
- Speech and Language Pathology
Background:
- Swallowing and breathing share physiological structures, meaning respiratory issues can lead to dysphagia.
- Chronic cough is a common respiratory symptom that may be linked to impaired swallowing function.
Purpose of the Study:
- To evaluate the pharyngeal phase of swallowing in individuals diagnosed with chronic cough.
- To identify potential aspiration risks associated with chronic cough.
Main Methods:
- A retrospective analysis of 15 patients diagnosed with chronic cough and aspiration risk factors.
- Patient history included swallowing, chewing, breathing, and feeding complaints.
- Videofluoroscopic examination was used to assess swallowing function.
Main Results:
- 40% of patients had chronic cough, 20% had asthma.
- 33.3% exhibited normal swallowing; mild dysphagia was present in 20%, mild-to-moderate in 6.7%.
- 73.3% had a Rosenbek scale degree of 1; 13.3% had degree 8. Stasis was observed in 69.2% of patients, with multiple swallowing being 100% effective.
Conclusions:
- Individuals with chronic cough may have subtle swallowing abnormalities and aspiration risks.
- Altered breathing patterns in chronic cough can disrupt the crucial coordination between breathing and swallowing.
- Early identification and intervention for swallowing dysfunction are vital for airway protection in chronic cough patients.

01:23Chronic Pharyngitis
15.6K
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,...

01:25Deglutition
8.2K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:20Pharynx
9.5K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

6.7K
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

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

01:30Pneumonia I: Introduction
1.4K
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
