Objectives:
Intracapsular tonsillectomy (tonsillotomy) has been used internationally, mainly in the management of obstructive sleep apnoea, rather than recurrent tonsillitis, with few published data evaluating its use for this latter indication. We present long-term prospective data from 500 paediatric cases undergoing Coblation® intracapsular tonsillectomy, for both obstructive and infective indications.
Design:
Prospective case series, March 2013-January 2016, all with completed follow-up.
Setting:
Tertiary paediatric otolaryngological practice.
Participants:
A total of 500 consecutive patients (6 months to 18 years, mean 5.1 years) undergoing Coblation® intracapsular tonsillectomy (with or without adenoidectomy), for obstructive and/ or infective indications, almost exclusively under the care of the senior author (DJT).
Main Outcome Measures:
Validated parent-reported T-14 tonsil symptom questionnaires were used in all cases pre- and postoperatively, including in the long term. Parents also recorded duration of analgesia, time to return to school, any complications and whether they would recommend the procedure.
Results:
With a mean follow-up 7.4 months, symptom control has been excellent (mean total T-14 score (/70) 31.01 preoperatively, 2.68 postoperatively, P<.0000001), with similar trends for obstructive and infective domains. Two small secondary haemorrhages required readmission and observation only (0.4%); otherwise, no complications, delayed discharges or readmissions occurred; 12/500 (2.4%) have since undergone revision tonsil surgery, 10 for obstructive and 2 for infective symptoms, the majority in very young children, with revision adenoidectomy at the same time. More than 99% of parents would recommend the surgery.
Conclusions:
Our experience of this technique has been very positive, with excellent control of both obstructive and infective symptoms, and exceptionally low rates of complications. Further work will be required to allow conclusive demonstration of its advantages over extracapsular tonsillectomy.

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,...
