Hypopharyngeal perforation following minor trauma: a case report and literature review
Abstract:
Hypopharyngeal perforation is mainly reported in association with high velocity road traffic accidents, or with low velocity direct blows to the neck. We report a case of hypopharyngeal perforation following a low velocity motorcycle accident where neither of these mechanisms of injury was apparent. A 52 year old man was referred from the emergency department (ED) with a sore throat and dysphagia, following a low speed side impact accident. A gastrograffin swallow demonstrated a posterior pharyngeal wall tear. After 11 days of conservative hospital treatment, he recovered and was discharged. The presumed mechanism of injury in this case was cervical spine hyperextension without cervical compression.

Esophageal Perforation-II: Clinical Manifestations and Management
Clinical Manifestations:
Peptic Ulcer
Chronic Pharyngitis
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,...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
