Introduction:
Dysphagia is a common presenting complaint and can often be due to pharyngoesophageal diverticulum, including Zenker's diverticulum. Iatrogenic pharyngeal diverticulum, occurring after anterior cervical spine surgery, is a rare cause of dysphagia.
Case Report:
We report the case of a 51-year-old man, with a history of anterior cervical fusion about ten years previously, who complained of chronic dysphagia and disabling episodes of aspiration. Anterolateral pharyngeal diverticulum in contact with the cervical screw plates was diagnosed on barium swallow and upper gastrointestinal endoscopy.
Discussion:
Pharyngeal diverticulum differs from Zenker's diverticulum in terms of its position and its origin. It may occur early or late after anterior cervical spine surgery. Treatment consists of endoscopic or open surgery via a neck incision. In our case, appropriate treatment allowed complete resolution of the patient's symptoms with no complications following rigorous postoperative surveillance.

Acute Pharyngitis
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:
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,...
