Many methods have been devised to repair cranial defects. Here, we report the use of a simple technique for the repair of a congenital cranial defect associated with aplasia cutis congenita (ACC). A newborn baby at 39 weeks of gestation was consulted with a scalp and cranial defect at the vertex measuring 3 × 1.5 cm. A 3-D CT scan of the skull confirmed the presence of a cranial defect at the sagittal suture and a normal brain structure. On the 13th day of life, the newborn was taken to an operating room. An autologous bone graft was harvested from adjacent normal parietal bone and grafted into the debrided congenital cranial defect. The soft tissue defect was then covered by rotation flaps. The postoperative 3-D CT scan presented a well-positioned autologous bone graft. At 1 month postoperatively, the skull contour was normal and there was no palpable defect. We report a successful surgical outcome for a congenital cranial and soft tissue defect in ACC treated using an autologous bone graft and rotation flaps. Although conservative therapy may be an alternative option, we recommend appropriate surgical reconstruction in patients at risk of potentially fatal complications.

Meningioma is the most common intracranial benign tumor in adults. Hyperostosis accompanies about 4.5% of meningiomas. The authors report a rare case of hyperostotic meningioma that may have been misdiagnosed as giant osteoma. A 42-year male visited our clinic due to an egg-sized, hard mass on his left forehead. The mass suspected to be giant osteoma was about 4.2 × 4.0 cm sized, hard, non-movable, and non-tender. But based on radiologic findings, the mass was diagnosed as meningioma with extensive hyperostosis. Without neurologic symptoms, the diagnosis of meningioma associated with hyperostosis can be challenging and be misdiagnosed as fibrous dysplasia and osteoma by simple examination without enhanced CT and MRI. Therefore, although osseous lesions are strongly suspected to be osteomas, surgeons should consider other diagnoses, and if necessary, use contrast enhanced CT or MRI to differentiate these bony lesions.

The authors compared facial scars after split-thickness skin grafts (STSGs) performed with a dermal substitute or after fullthickness skin grafts (FTSGs) in facial defect. Materials and Methods: The medical records of patients who had undergone FTSG or STSG with dermal substitute after skin cancer surgery between March 2016 and December 2018 were retrospectively reviewed. The scars resulting from skin grafts were assessed using the patient and observer scar assessment scales (PSAS and OSAS) in our clinic after a minimum of 6 months postoperatively. Results: Of the 50 study subjects, 35 patients (FTSG group) received FTSG only and 15 patients (STSG group) received STSG with the dermal substitute. The total scores of PSAS and OSAS were significantly lower in the FTSG group and it is suggested that both patients and observers thought that better scar outcomes were achieved when FTSGs were used. However, for defects smaller than 1.8 cm 2 and defects located in the periorbital area, there was no statistically significant difference in the scores of PSAS and OSAS in the 2 groups. Interestingly, for defects located in the periorbital area, although there was no significant difference, PSAS and OSAS scores were lower in the STSG group than in the FTSG group. In other word, scar outcomes in the STSG group were better. Conclusions: Although there was no significant difference, unlike what we usually know, our result shows that STSG with dermal substitute tended to produce comparable or rather better results than FTSG under some conditions.
