چکیده (انگلیسی):

Background: The reliability of X-ray radiography for diagnosing nasal bone fractures
(NBFs) remains controversial. Recent studies show that, for determining the orientation
and location of the displaced/depressed fracture, nasal sonography is as accurate as facial
computed tomography. This retrospective study compared conductor-assisted nasal sonography
(CANS) to conventional diagnostic tools and reported subjective patient satisfaction and
discomfort after closed reduction combined with tube technique.
Methods: This retrospective study reports the results of 329 refinement treatments for
nasal bone fracture (including 199 men and 130 women) performed from 2005 to 2011.
All patients were assessed with CANS and completed a survey immediately prior to
removing the packing. Questionnaires were adapted from the nasal obstruction symptom
evaluation (NOSE) scale.
Results: The study found that CANS has a 97.2% rate of accuracy in diagnosing NBF. The visual
analog scale scores of nasal obstruction, nasal congestion, sleep disturbance, trouble
breathing, and inability to move air through the nose were analyzed. The experimental
group scores were significantly different from the control group for all scores (p < 0.001).
Conclusion: Compared to conventional methods, CANS is more accurate for detecting NBF.
We recommend its use as an alternative tool for diagnosing a nasal fracture. Because the tube technique balances pressure between the nasopharynx and middle ear during swallowing,
patient comfort is enhanced. Application of these modifications can improve accuracy
in diagnosing NBF and can improve the quality of NBF treatment.
