Management Of Calcified Cephalohematoma Of Infancy: The University Of Michigan 25-Year Experience

Background: Cephalohematoma of infancy is the result of a subperiosteal blood collection that usually forms during birth-related trauma. A small proportion of cephalohematomas can calcify over time, causing a permanent calvarial deformity that is only correctable with surgery. The authors present a technique for the excision and reconstruction of calcified cephalohematoma and their management experience over the past 25 years.Methods: All patients with a diagnosis of calcified cephalohematoma between 1994 and 2019 were identified. Patients were included if the diagnosis was confirmed by a pediatric plastic surgeon or a neurosurgeon. All patients underwent surgical evaluation followed by surgical intervention or observation. Patient demographics and potential risk factors for both surgical and nonsurgical groups were compared using chi-square or Fisher's exact test. Additional data were collected for the surgical cohort.Results: Of 160 infants diagnosed with cephalohematoma, 72 met inclusion criteria. Thirty patients underwent surgical treatment. There was no significant difference in demographics, baseline characteristics, or potential risk factors between the operative and nonoperative groups. Mean age at the time of surgery was 8.6 months. Twenty-one surgical patients (70 percent) required inlay bone grafting. All surgery patients had improvement in calvarial shape. The main risk of surgery was blood loss requiring transfusion [eight patients (26.7 percent)]. Thirteen percent of patients experienced minor complications.Conclusions: This series of 72 children with calcified cephalohematomas, 30 of whom required surgical intervention, is one of the largest to date. The technique presented herein demonstrated excellent surgical outcomes by restoring normal cranial contours and was associated with a low complication profile.CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
