Background: In order to facilitate measurement and reduce radiation exposure,
we developed a simple method to replace the Haller method for evaluating the severity of pectus
excavatum (PE).
Methods: We retrospectively reviewed medical records of patients diagnosed with PE (ICD9
code 754.81) from April 2005 to November 2010 at Tri-service General Hospital, Taipei, Taiwan.
The patients were divided into two groups: an adult group (>20 years old) and a pediatric
group (20 years old). The sternum index (SI) was calculated according to the anterioposterior
diameter of the chest cavity, from the sternum to the spine, divided by the patient’s height
(SI Z anterioposterior diameter of the chest cavity/the patient’s height × 100). We compared
these values with the Haller index (HI Z the transverse diameter of the chest cavity/the anterioposterior
diameter) using coefficients of variation, Pearson’s correlation, and multiple
linear regression analyses.
Results: A total of 109 patients (97 males and 12 females) who underwent the Nuss procedure
for correction of PE were included in the study. Both groups showed a smaller coefficient of
variation for the preoperative SI than that of the HI, Pearson’s correlation showed a good relationship
between the HI and the preoperative SI, and multiple linear regression analyses
revealed that the preoperative SI was a good predictor of the HI. |
