چکیده (انگلیسی):

Background: Surgical treatment for inferior turbinate (IT) is selected to treat severe allergic rhinitis (AR) that
is unresponsive to conservative treatment. This study aimed to determine the clinical effects of outpatient submucosal
IT surgery (OSITS) on patients with severe AR.
Methods: Between January 2008 and August 2012, 95 patients with severe AR who underwent OSITS at the
Department of Otolaryngology, Hyogo College of Medicine, were retrospectively analyzed. There were 53 men
and 42 women. Their mean age was 27 years (11-75 years). OSITS was bilaterally performed using a bipolar
radiofrequency electrocautery under local anesthesia. Symptoms, QOL, and physical findings were evaluated
using scores from both pre- and postoperative periods (average: 12.4 months), according to Practical Guideline
for the Management of AR in Japan 2009.
Results: In perennial AR, all mean scores of nasal symptoms, QOL, and physical findings significantly improved
after OSITS (p < 0.05, n = 83). Nasal obstruction, sleep problems, and IT congestion were the most
strongly affected. Eye symptoms were not influenced by OSITS. OSITS also showed significant effects on nasal
obstruction and IT congestion in seasonal AR (p < 0.05, n = 12), but not sneezing, nasal discharge, and
QOL. In terms of the efficacy, OSITS was beneficial in 90% of perennial AR cases and 75% of seasonal AR
cases. Epistaxis (1%), vestibulitis (1%), and IT atrophy (4%) were observed after OSITS.
Conclusions: These data indicate that OSITS using radiofrequency electrocautery could be a beneficial
therapeutic option in patients with severe AR
