AIM: To discuss a special type of skull lesion detected after delivery. We reviewed our experience on scalp swelling in term neonates to further investigate the relationship between cranial injuries and labor process. MATERIAL and METHODS: A total of 55 newborns with scalp swellings were assessed with medical records retrospectively between January 2007-July 2017. A radiologist and a pediatric neurosurgeon re-analyzed all skull X-ray images via picture archiving and communication system of the hospital. RESULTS: A special type of skull fracture, called Kanat (wing) fracture, was detected. The fractures appeared unique, were located in the midline parietal bone, and were difficult to detect by X-ray. Kanat fractures accounted for 12.7% of the 55 cases (n=7). Patients without (group-1) and patients with (group-2) Kanat fractures were compared based on the head circumference of the newborns (p=0.881), fetal birth weight (p=0.20), maternal age (p=0.04), duration of second stage of labor (p=0.217), maternal body mass index (p=0.278), total labor time (p=0.922) and parity (p=0.375). No statistically significant difference between the two groups was determined for the compared parameters. CONCLUSION: The present study is the first research describing and discussing the possible effects of maternal, fetal and delivery characteristics on Kanat fractures. Designing clinical and experimental researches to enhance awareness and acknowledgement of skull injuries and labor process could improve the clinical outcome of the newborns.
