Insights
This study shows that using reusable bipolar forceps electrocautery (RBFE) with adenoidectomy effectively reduces tonsil size in children with obstructive sleep apnea (OSAS). The procedure is safe, quick, and minimizes bleeding risks.
Area of Science:
- Otolaryngology
- Pediatric Sleep Medicine
- Surgical Innovation
Background:
- Pediatric obstructive sleep apnea (OSAS) is often associated with tonsillar hypertrophy.
- Tonsillectomy is a common treatment, but alternative methods for tonsil size reduction are being explored.
Purpose of the Study:
- To introduce and evaluate the safety and efficacy of tonsil size reduction using reusable bipolar forceps electrocautery (RBFE) in children with OSAS.
- To assess the impact of RBFE tonsillotomy on polysomnographic parameters and quality of life.
Main Methods:
- A prospective study included 30 children (2-15 years) diagnosed with OSAS (Apnea-Hypopnea Index [AHI] > 5).
- Participants underwent adenoidectomy combined with RBFE tonsillotomy.
- Tonsil size, AHI, minimum oxygen saturation (SaO2 min), and Pediatric Sleep Questionnaire (PSQ) scores were assessed pre- and post-operatively.
Main Results:
- RBFE tonsillotomy was performed safely without intraoperative or postoperative complications like bleeding or dehydration.
- Significant reductions in AHI (10.9 to 1.8) and improvements in SaO2 min (86.1% to 93.2%) were observed (p<0.001).
- Tonsil size decreased significantly, and PSQ scores improved substantially one month and one year after surgery.
Conclusions:
- RBFE tonsillotomy combined with adenoidectomy is a safe and effective method for reducing tonsil size in pediatric OSAS.
- This technique offers an inexpensive, rapid, and low-bleeding alternative, potentially beneficial for patients with coagulation issues.
Objective:
To present, for the first time, tonsil size reduction using reusable bipolar forceps electrocautery (RBFE), as a treatment for pediatric OSAS and to assess the safety and efficacy of the procedure.
Methods:
A prospective interventional design study was performed. Thirty children aged 2-15 years with OSAS (AHI>5) diagnosed by means of polysomnography were included. All children were treated with adenoidectomy and RBFE tonsillotomy without dissection. Re-polysomnography was performed after 1 year. The size of the tonsils was blindly assessed by two ENT specialists and the parents were asked to fill out 'Pediatric Sleep Questionnaires' (PSQ), before surgery, and one month and one year after surgery.
Results:
There were no complications during or after surgery. There were no events involving postoperative bleeding or dehydration. The surgery mean time, including adenoidectomy, was 20.6min. The AHI was 10.9 before surgery and decreased to 1.8 after surgery (p<0.001), minimum saturation (SaO2 min) increased from 86.1% to 93.2% (p<0.001). The size of the tonsils decreased from a mean of +3.3 before surgery to +1.3 and +1.4 one month and one year after surgery, respectively. The mean of the PSQ scores went down from 23.6 to 5.5 and to 6.2 one month and one year after surgery, respectively.
Conclusion:
We demonstrated that simple cauterization of the tonsils using a RBFE device with an adenoidectomy is a safe and effective treatment to decrease tonsil size in OSAS. In addition, the method is inexpensive, rapid and does not cause bleeding, which may be particularly interesting in the presence of coagulation problems.

Etiology
Three primary contributing factors have been identified.
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,...
