Microdebrider-assisted partial tonsillectomy: short- and long-term outcomes.
Microdebrider-assisted partial tonsillectomy has gained popularity in recent years. However, no prospective long-term follow-up exists in the literature and the risk of increase in tonsillitis is still a concern. We conducted a prospective randomized controlled study to assess the short-term benefits of microdebrider-assisted partial tonsillectomy (group 1) compared to electrocautery-assisted total tonsillectomy (group 2), to monitor the durability of the improvement and watch for any change in the rate of tonsillitis. Patients with symptomatic tonsillar hyperplasia were included and underwent either technique of tonsillar surgery. Duration of operation, amount of intra-operative blood loss, immediate and late complications, postoperative pain, return to normal activity and diet, and relief of obstructive symptoms were measured. Recurrence of symptoms and change in rate of tonsillitis in group 1 were monitored. We studied 143 patients, 77 in group 1 and 66 in group 2. There was no significant difference in the surgical time (P>0.05) or postoperative bleeding (P>0.05) but more blood loss in group 1 (P<0.05) and more dehydration in group 2 (P<0.05) were encountered. All patients had complete relief of symptoms. Group 1 returned earlier to normal activity (2.19 vs. 5.71 days; P<0.05), to normal diet (5.28 vs. 8.16 days; P<0.05) and needed less frequent analgesics (2.14 vs. 6.1 days; P<0.05). More than two-thirds of group 1 and less than one-third of group 2 were pain free after day 3. Most group 1 parents (96.1%) were highly satisfied, at initial follow-up, regarding the decision to perform the surgery in contrast to group 2 parents (19.7%). No recurrence of symptoms and no increase in rate of tonsillitis were noticed among group 1 after 20 months mean follow-up (median 20.6, range 1-36.2 months). Group 1 showed short-term benefits over group 2 and maintained the resultant improvement on the long-term with no infectious drawbacks.
