In order to compare and evaluate bilateral inferior turbinectomy (BIT) and
submucosal diathermy (SMD), we retrospectively examined these two well-know
n techniques for treatment of nasal obstruction due to bilateral congestion
of the inferior turbinates. One hundred patients with bilateral nasal obst
ruction were divided into 4 groups according to their nasal airflow patency
. Forty-nine patients underwent BIT, and 51 patients underwent SMD. All 100
patients were followed for 2 months after surgery. Patients with difficult
postoperative courses were followed up to 1 year after surgery, in order t
o decide on the necessity of operative revision. Postoperative improvement
in nasal breathing after BIT was reported for 96% of patients 2 weeks after
surgery, and for 88% 2 months after surgery. Only 1 BIT patient had to und
ergo revision operation. Diathermy showed good results in 78% of cases 2 we
eks after surgery. The efficacy of the procedure was reduced to 76% 2 month
s after surgery. Twenty percent of SMD patients were advised to undergo ope
rative revision. Postoperative bleeding occurred in 20% of BIT patients and
in only 4% of SMD patients. We found that the extent of postoperative impr
ovement does not depend on preoperative conditions; therefore, it is imposs
ible to predict the extent of postoperative improvement on the basis of the
results of preoperative assessment. Both procedures can be performed under
local anesthesia, are relatively safe and effective, and do not need expen
sive instrumentation that may not be available in many medical centers.
