Abstract:
A review was made of 77 rigid esophagoscopies to remove a foreign body from the upper digestive tract. Mean age of patients was 59 years. Meat bones were the most frequent impacted foreign body and the cervical esophagus was the most frequent site of impactation. No foreign body was found in 22% of esophagoscopies, a high rate that could have been due to our lack of confidence in radiographic studies, which yield false positive and false negative information. Esophagoscopy is performed whenever patient-referred symptoms are clear. The only complications were three cases of major esophageal erosions without perforation and one pneumothorax. A case of intramural esophageal pseudodiverticulosis was found.

Pharynx
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...
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...
