Background: This study aims to investigate the demographic characteristics and familial inheritance of pectus deformities across Turkey.

Methods: Demographic characteristics of a total of 5,098 patients (5,028 males, 70 females, mean age 23.6 years; range, 1 to 56 years) with pectus excavatum and pectus carinatum admitted to our outpatient clinic between January 1996 and December 2018 were retrospectively analyzed. The distribution of the patients across the country was made according to seven regions and 81 provinces. Familial inheritance was investigated using patients" data obtained from the clinical records and telephone calls.

Results: Of all patients, 3,330 (65.3%) had pectus excavatum and 1,768 (34.7%) had pectus carinatum deformity with a pectus excavatum-to-pectus carinatum ratio of 1/1.9. In the Southeast Anatolia region, the rate of pectus excavatum was lower than the overall average and higher in the Marmara region (p=0.009 and p=0.037, respectively). In the Southeast Anatolia region, the rate of pectus carinatum was higher than the general average and lower in the Marmara region (p=0.001 and p=0.003, respectively). Kastamonu, Çankırı, Karabük, and Sinop were the most common provinces for pectus deformity cases. Family history was positive in 39% of pectus excavatum and 43% of pectus carinatum patients. All regions showed a similar distribution in terms of the presence of family history.

Conclusion: This is the first study to report the distribution of pectus deformities in Turkey and the high frequency of pectus deformities in certain regions and provinces of Turkey indicates familial inheritance.
