An interventional study of Blunt Dissection and Bipolar Radiofrequency in Tonsillitis Chronic and Tonsillitis Recurrent, sponsored by Tanta University. Completed at 1 site in Egypt. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Tanta University · Not applicable, Interventional, and Treatment
The aim of this study is to assess the effectiveness of bipolar radiofrequency techniques of tonsillectomy in adults.
Tonsillectomy is one of the commonest procedures performed in otorhinolaryngology, accounting 20%-40% of surgical procedures performed in this field.
The techniques of tonsillectomy can be broadly divided into 2 major categories: extracapsular (total tonsillectomy, subcapsular) and intracapsular (partial tonsillectomy). Intracapsular is also known as "subtotal," and this procedure is also referred to as tonsillotomy.
103 studies on the registry are indexed under Tonsillitis; 12 are open to participants now.
This study's enrollment of 56 is below the median of 100 across 87 interventional studies indexed under Tonsillitis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Patients underwent blunt dissection tonsillectomy.

Procedure: Bipolar Radiofrequency
Patients underwent blunt dissection tonsillectomy.
Patients underwent bipolar radiofrequency tonsillectomy.
Intraoperative bleeding
Intraoperative bleeding was evaluated by the amount of blood loss calculated by the following method: * Number of cotton balls used = a * Approximate amount of blood in a cotton ball = 2.5 ml * Amount of blood in cotton balls (b) = 2.5 X a * Amount of fluid (blood and known amount of used saline) collected from the suction bottle = c * Amount of used saline = d * Amount of blood in suction bottle (e) = (c-d) * Total amount of blood loss = (b+e)
Time frame: From the start to the end of surgery (Up to 60 minutes)
Intraoperative time
Intraoperative time was measured using a stopwatch from the start of incision till removal of the mouth gag.
Time frame: During surgery, from the first incision until removal of the mouth gag (Up to 60 minutes)
Degree of pain
Degree of pain was assessed using the visual analogue scale (VAS). The distance was measured in millimetres and interpreted as follows: * 0 to 4 mm - No Pain * 5 to 44 mm - Mild Pain * 45 to 74 mm - Moderate Pain * 75 to 100 mm - Severe Pain VAS was also more convenient in monitoring pain progression; the patient could indicate the level of increased or decreased pain on the scale which could be compared with the earlier level of pain
Time frame: 2 weeks postoperatively
