A Comparative Study on Outcome of Tonsillectomy by Coblation and Conventional Dissection Technique at a Tertiary Care Centre
摘要
Tonsillectomy is a commonly performed surgical procedure in the field of Otorhinolaryngology. Although commonly performed it is associated with significant morbidity. There are various techniques for tonsillectomy based on the instrument used for surgery. Each method has its own advantages and drawbacks in terms of intraoperative blood loss, postoperative pain, recovery time and complications. To compare the outcome of coblation and conventional dissection method for tonsillectomy in terms of intraoperative blood loss, postoperative pain and incidence of reactionary and secondary haemorrhage and also to evaluate return to normal diet, healing time of tonsillar fossa and incidence of complications. A prospective observational study was conducted from September 5, 2023, to March 4, 2025, on a total of 60 patients who met the inclusion criteria. After acquiring Institutional Research Committee and ethics Committee approval, patients who met the eligibility criteria were enrolled in the study after obtaining written informed consent and assent. The patients were categorized into two groups based on the method of tonsillectomy. Data were collected on intraoperative blood loss, postoperative pain, postoperative haemorrhage, slough formation, time taken to return to a normal diet and daily activities, as well as other complications. Coblation tonsillectomy resulted in significantly less intraoperative blood loss than conventional dissection tonsillectomy (p = 0.002). Postoperative pain was significantly more in coblation tonsillectomy. Slough formation was similar in both techniques postoperatively, but conventional dissection tonsillectomy showed faster slough resolution, indicating early healing of fossa. Coblation tonsillectomy minimizes blood loss but may delay healing, while dissection tonsillectomy, despite higher blood loss, promotes faster recovery. The choice of technique should consider patient needs, surgeon’s experience and availability of equipment.
