Ultrasonic tonsillectomy: rationale and technique.
Dissection using ultrasonic aspiration is characterized by its unique tendency to spare fibrous and vascular structures during removal of parenchymal lesions. This preliminary study was undertaken to evaluate the feasibility and efficiency of tonsillectomy using the ultrasonic aspirator. Tonsillectomy was performed on 23 patients using the ultrasonic aspirator. Pericapsular removal of the tonsil was easily accomplished with complete preservation of the tonsillar pillars and minimal peritonsillar trauma. The ability to identify significant vasculature before transection, and the constant aspiration integrated into the ultrasonic aspirator allowed excellent visualization of the operative field at all times. No postoperative complications were noted and recovery was typical for tonsillectomy patients. The ultrasonic aspirator may increase the efficiency and margin of safety of tonsillectomy.
