Summary
Foreign objects are a risk during dental procedures. This case highlights impression material lodged in the hypopharynx, which was not visible on X-rays.
Area of Science:
- Dental Surgery
- Medical Imaging
- Otolaryngology
Background:
- Foreign object ingestion/aspiration is a known complication of dental procedures.
- Commonly ingested/aspirated items include endodontic instruments and metallic materials.
- These materials are often identifiable via radiography due to radiodensity.
Purpose of the Study:
- To report an unusual case of foreign body impaction in the hypopharynx.
- To highlight a case where the foreign body was not radiographically detectable.
Main Methods:
- Case report of a patient presenting with a lodged foreign object.
- Clinical and radiographic examination of the hypopharynx.
- Surgical removal of the foreign object.
Main Results:
- Impression material was found lodged in the hypopharynx.
- The impression material was not detectable using standard radiographic imaging.
- The foreign body was successfully removed.
Conclusions:
- Impression materials pose a risk for aspiration during dental procedures.
- Radiographic detection of aspirated foreign bodies is not always possible.
- Clinical vigilance is crucial for diagnosing non-radiopaque foreign body impactions.

01:23Chronic Pharyngitis
6.9K
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,...

367
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

203
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:28Esophageal Perforation-II: Clinical Manifestations and Management
205
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
