Original Article



The aim of this study was to show the difference between the pulmonary function of children with mild or severe types of pectus excavatum (PE) and post-operative changes in their predicted vital capacity (%VC) following Nuss procedure.

Patients and methods

One hundred and twenty-four of the 208 children who underwent Nuss procedure for PE between January 2007 and March 2016 were deemed eligible for this study and evaluated retrospectively. A spirometry was performed on these children on four occasions: before operation; pre-bar removal; and 1 month and 1 year after bar removal. Ninety-seven of the children who were more than 7 years of age were divided using the Haller Index (HI) into a mild group (n = 54) and a severe group (n = 43) and compared. The children were also divided into three groups based on their age and their %VC was compared at each follow-up occasion.


The severe group showed a significantly lower %VC and peak expiratory flow rate than the mild group. %VC change after bar removal showed significantly lower in group aged 11 or over. 43 of the children had spirometry data recorded 1 year after bar removal which, compared with 1 month after bar removal, showed a significant higher %VC in groups aged of 10 or under.


Nuss procedure in children aged of 10 or under proved to be an advantage in the post-operative pulmonary function.
