Summary
Vessel sealing systems (VSS) significantly reduce operative time, bleeding, and pain during tonsillectomy compared to conventional methods. Harmonic Scalpel (HS) and Coblation showed no significant advantages over conventional tonsillectomy.
Area of Science:
- Otolaryngology
- Surgical Technology
- Evidence-Based Medicine
Background:
- Tonsillectomy is a common surgical procedure.
- Minimally invasive techniques aim to improve outcomes.
- Comparison of new technologies with conventional methods is essential.
Purpose of the Study:
- To systematically review evidence on technology-assisted tonsillectomy.
- To compare operative time, bleeding, and pain with conventional techniques.
Main Methods:
- Systematic search of randomized controlled trials.
- Comparison of vessel sealing systems (VSS), Harmonic Scalpel (HS), and Coblation against cold steel/electrocautery (CS/EC).
- Meta-analysis of 33 trials with 3139 patients.
Main Results:
- Vessel sealing systems (VSS) significantly reduced operative time, perioperative bleeding, postoperative bleeding, and pain compared to CS/EC.
- Harmonic Scalpel (HS) significantly reduced perioperative bleeding but showed no other advantages.
- Coblation demonstrated no significant differences compared to CS/EC.
Conclusions:
- Coblation and HS offer no significant benefits over conventional tonsillectomy.
- Vessel sealing systems (VSS) show significant advantages in reducing operative time, bleeding, and pain.
- Further research on VSS is warranted due to limited and heterogeneous data.

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
01:23Chronic 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,...
