Study Finds Starion Instruments' Tissue Welding Technology Enhances Patient Recovery from Tonsillectomy Procedures

Sunnyvale, Ca. – August 23, 2011 – Starion Instruments, a Microline Surgical company, today announced that a study published in the European Archives of Otorhinolaryngology found the use of Starion’s proprietary tissue welding technology in adult tonsillectomy patients resulted in less pain, faster recovery times and fewer complications compared with conventional monopolar electrocautery.

The study was conducted at Paijat-Hame Central Hospital in Lahti, Finland by Drs. Juha Silvola, Aarre Salonen, Jouko Nieminen and Hannu Kokki. Silvola and his colleagues conducted a single-blind, randomized clinical trial with two parallel patient groups to evaluate whether tissue welding may improve recovery following tonsillectomy.

The trial included 60 healthy adult day-surgery patients, 31 of whom underwent tonsillectomies with Starion’s ENTceps, which features the company’s tissue welding technology, and 29 who underwent the procedure with a monopolar electrocautery device. The researchers recorded intraoperative events and short- and long-term recovery for two weeks post-operatively.

For the patients who underwent tonsillectomies with Starion’s ENTceps, researchers found that recovery was significantly faster, the duration of post-operative pain was two days shorter, normal daily activities were less affected, there was a lower incidence of post-operative bleeding, there was less need for hospital contact following discharge and patient satisfaction was significantly higher compared to patients in the monopolar electrocautery group. Furthermore, while three patients in the electrocautery group developed secondary hemorrhage and required electrocautery to control the bleeding, no patients in the ENTceps group experienced this post-operative complication.

The researchers concluded that Starion’s tissue welding technology provided an earlier return to normal activities and less affected sleep patterns compared with electrocautery tonsillectomy. They noted that if subsequent large studies confirm that tissue welding is associated with fewer bleeding complications after surgery, the technique “could be considered as a significant innovation in the field of ENT surgery.”

The study, Tissue welding tonsillectomy provides an enhanced recovery compared to that after monopolar electrocautery technique in adults: a prospective randomized clinical trial, which was published in the February 2011 edition of the journal, can be found on the publisher’s website:
