Abstract

Background and Objectives : Acoustic rhinometry (AR) is a convenient method for
measurement of the cross-sectional area and volume in the nasal cavity, initially
described by Hilberg et al(1989). It is an objective method based on the reflection of an
acoustic signal entering the nasal cavity and has several advantages including
non-invasiveness, little requirement of patient's cooperation, cheap cost, high
reproducibility and ease to perform. It is presented as a 2-dimensional function of the
distance from the nostril and repressent the geometry of the nasal cavity. We evaluated
the effect of intranasal polypectomy on the nasal geometry using acoustic rhinometry.
Materials and Methods : We asked the presense of the nasal obstruction before and
after nasal polypectomy in 17 patients (including 33 nostrils) and perfomed pre- and
postoperative acoustic rhinimetry after decongestion. Preoperative predecongestive
rhinometry rhinometry was also performed.
Results : We detected significant increment of the cross-sectional area at 4cm from
the nostril(CA4.0) after decongestion compare to CA4.0 before decongestion in
preoperative state. CA4.0 and unilateral nasal volume after decongestion in postoperative
state were also increased significantly compared to preoperative state after decongestion.
These results were clinically correlated with improvement of subjective nasal
obstruction.
Conclusions : We suggest that acoustic rhinometery is a useful method for objective
evaluation of intranasal geometry after nasal polypectomy and has a good correlation
with the change of subjective symptom.
