Chronic Pharyngitis

Chronic Pharyngitis

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,...

Area of Science:

Otolaryngology
Minimally Invasive Surgery
Surgical Technology

Background:

Previous audits in 2005 and 2006 indicated potential drawbacks of laser tonsillectomy, including increased postoperative pain and delayed healing.
Concerns were raised regarding postoperative hemorrhage and medium-term pain associated with laser techniques compared to traditional dissection.

Purpose of the Study:

To systematically review current literature on laser tonsil surgery.
To assess trends in postoperative pain, hemorrhage, and healing time compared to other tonsillectomy methods.

Main Methods:

A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted in July 2019.
Searched Embase, Medline, and Cochrane databases for randomized controlled trials comparing laser tonsil surgery with non-laser techniques.
Included studies used terms like 'laser,' 'tonsillectomy,' and 'tonsillotomy' for nonmalignant conditions; 14 articles were analyzed.

Main Results:

The review analyzed 1133 patients (2266 tonsil removals) using various laser (CO2, KTP, diode) and non-laser (dissection, diathermy, coblation) techniques.
Laser techniques demonstrated superiority in reducing intraoperative bleeding and procedure duration.
Outcomes for postoperative hemorrhage, pain, and healing time were equivocal or superior with laser methods.

Conclusions:

Recent outcomes suggest significant improvements in laser tonsil surgery.
Enhanced surgeon experience and routine performance in specialized centers likely contribute to better results.
Laser tonsillectomy appears to be a safe and effective option with evolving technique proficiency.
