Chronic Pharyngitis01:23

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,...

Summary
This summary is machine-generated.

The harmonic scalpel tonsillectomy (HST) shows reduced intraoperative blood loss and less postoperative pain compared to conventional steel tonsillectomy (CST). HST also significantly lowers the risk of secondary hemorrhage after tonsillectomy.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Minimally Invasive Surgery

Background:

  • The harmonic scalpel tonsillectomy (HST) has been utilized for 5-6 years in Western Europe and North America.
  • Despite some studies indicating superiority, its adoption in tonsillectomy remains limited.
  • Conventional steel tonsillectomy (CST) often involves bipolar diathermy or ligatures for hemostasis.

Purpose of the Study:

  • To evaluate intraoperative events and postoperative morbidity associated with harmonic scalpel tonsillectomy (HST).
  • To compare HST with conventional steel tonsillectomy (CST) regarding operative time, blood loss, and pain.
  • To assess the efficacy of HST in reducing secondary hemorrhage post-tonsillectomy.

Main Methods:

  • A single-blinded prospective study involving 180 patients undergoing HST and 100 patients undergoing CST across two hospitals.
  • Patients were randomized regardless of age, sex, medical history, or surgical indication.
  • Comparison focused on surgical duration, intraoperative blood loss, and postoperative pain in subgroups (120 HST, 70 CST).

Main Results:

  • Mean operative time for HST was comparable to CST.
  • Intraoperative blood loss was significantly lower in the HST group.
  • Postoperative pain was less severe in the HST group, with no major hemorrhages requiring surgical intervention.

Conclusions:

  • Harmonic scalpel tonsillectomy (HST) demonstrates a significant advantage over conventional steel tonsillectomy (CST) in reducing secondary hemorrhage.
  • HST is a safe and effective alternative, potentially superior to conventional methods for minimizing post-tonsillectomy bleeding.
  • While CST with disposable blades mitigates Creutzfeldt-Jakob disease transmission risk, HST offers superior hemorrhage control.
