5. Study Description

Brief Summary
Patients 13-years-or older who undergo tonsillectomy operation (without another additional surgery) will be enrolled in the study. Randomly, one side is going to be operated with conventional cold-knife technique and hemostasis will be maintained with bipolar diathermy (25-30w). Contralateral tonsil is going to be operated with needle-tip monopolar electrocautery (10-12w) at Blend 1 mode and hemostasis will also be maintained with needle-tip monopolar cautery. Postoperative tonsillar fossa healing and pain is going to be evaluated for both sides separately with Visual Analogue Scale. All operations are going to be performed by a single surgeon and all evaluations are going to be carried out by another surgeon in a totally blinded fashion to avoid possible bias.
Detailed Description
Comparison of cold and hot tonsillectomy carried out with needle-point tip monopolar electrocautery: a prospective, randomized, blinded, controlled (paired design) : A Randomized Clinical Trial Tonsillectomy surgery techniques are basically divided into cold steel knife dissection and other (hot) techniques where surgeons use electrocautery and other contemporary technological devices. Pros / cons of hot and cold techniques have been long researched in the literature. Parameters are: cost, postoperative bleeding rate, postoperative pain. (Leinbach RF) Latest research proved that monopolar electrocautery (EC) is ideal when cost/postoperative bleeding rate ratio is concerned. (Cunningham LC) Although EC presents as a viable option, hot techniques - although providing good advantages - result with a more painful postoperative period. Trade-off with electrosurgery is the heat generated to cut/coagulate the tissue also causes a variable amount of tissue necrosis consequent to thermal injury. This pain is associated with the thermal injury and consequent tissue necrosis. (Hetzler D) Needle electrocautery tips are thinner compared to conventional bovie tip. Their surface area is smaller and according to the study carried out by Farnworth et al. (Farnworth TK) cause reduced thermal injury compared to conventional blade tip. The investigators' aim in this study is to compare cold-knife dissection + bipolar diathermy tonsillectomy with needle tip EC monopolar cautery. Study design was prospective, randomised, single-blinded and controlled (paired). Either right tonsil was operated with standard-needle electrocautery, contralateral side was operated with cold-technique; or vice-versa. Which side received which treatment was randomly assigned (Aksoy F) Surgical Technique Both tonsils were injected with lidocaine and epinephrine infiltration to anterior tonsillar plica before the operation. All surgeries were performed by the primary investigator (BO) under x2.5 loupes. Force 2 Electrosurgical Generator (The Valley Lab, Boulder,CO) was used to power both the monopolar and bipolar electrocautery. Bipolar cautery was used (25-30 Watts) in accordance with the literature. Monopolar electrocautery settings were adjusted to 'Blend 1' which is a summation of the coagluation and cutting waveforms (75% cutting, 25% coagulation). Cut power was adjusted to 10W, whereas coagulation power was set to 12 Watts. Results and Evaluations Postoperative tonsillar fossa healing and pain is going to be evaluated for both sides separately with Visual Analogue Scale. All operations are going to be performed by a single investigator and all evaluations are going to be carried out by another investigator in a totally blinded fashion to avoid possible bias. These evaluations are going to be carried out for 10 postoperative days. Tonsillar fossa healing will be evaluated according to scale reported by Magdy EA et al. on first, fifth and tenth postoperative day (Magdy EA). Patients will evaluate their pain 10 (maximum) , 0 (none) based on a Visual Analogue Scale. Results will be calculated as (mean+-SD) and compared statistically for significance with SPSS. Discussion A finer tip can give greater precision in dissection and can also affect the dispersion characteristics of the energy used to perform the dissection. The implication of this for tonsillectomy is that greater precision in dissecting the tonsil from the underlying muscle can potentially lead to less post-operative discomfort. For those surgeons who choose to use an electrocautery technique for tonsillectomy, the greater precision of the needle-tip EC may enhance the results.
