Objective:
To determine the evidence for efficacy of tonsillectomy in reducing the incidence of recurrent pharyngitis.
Data Sources:
Literature databases consisting of PUBMED, SCOPUS, CINHAL AND OVID EMBASE including all languages.
Review Methods:
Literature search of database by 2 authors with structured criteria using an online database. Selected studies evaluated with meta-analysis.
Results:
In four randomized, controlled trials tonsillectomy was favored over medical therapy in reducing pharyngitis. The difference was statistically significant in only one study. Overall meta-analysis results were significant, indicating that tonsillectomy results in a reduction of about 43% in the incidence of pharyngitis. The number needed to treat with tonsillectomy to prevent one sore throat per month for the first year after surgery was 11 (95% CI; 7-23).
Conclusion:
Tonsillectomy reduces the incidence of recurrent pharyngitis to a modest degree.

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,...
Tonsillitis II: Management
Tonsillitis I: Introduction
Etiology
Three primary contributing factors have been identified.
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:
Streptococcal Pharyngitis
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...
