Introduction: It is generally believed that early postnatal wounds in neonates heal without scarring. We investigated skin injuries during delivery and subsequent scarring and healing in neonates delivered at Kanto Rosai Hospital.
 Methods: This retrospective study included 83 neonates with skin injury during delivery. We analyzed their medical records and clinical photographs and recorded the incidence of skin injuries by delivery method, site, and scarring status at 1 month of age.
 Results: Forceps deliveries carried a high incidence of skin injuries (14.29%), of which 19.35% occurred on both sides of the head and neck. Of the 83 neonates enrolled in this study, 80 were followed up to 1 month of age, of which two developed scarring.
 Discussion: Our findings suggest that neonates develop scarring of skin injuries during delivery if appropriate wound management is not provided.
 Conclusion: To avoid scarring of skin injuries during delivery, collaboration is required among obstetricians, pediatricians, nurses, and midwives to ensure that appropriate wound management starts immediately after birth.

 Nonsurgical treatments using various materials for congenital auricular deformities have been reported. However, there is no established standard treatment and material. At our institution, we use hydrocolloid dressing materials to correct auricular deformities. Herein, we report the effectiveness and safety of this method.
 We retrospectively investigated pretreatment classification of congenital auricular deformity, age at first visit, duration of treatment, and effect of treatments in 27 ears of 16 cases. Treatment was started at the first visit. To correct the auricular deformities, Duoactive^® CGF, a hydrocolloid material, was pasted to fill the scaphoid fossa and the auricle form was fixed. The effect of the treatment was evaluated by five plastic surgeons into three grades.
 Ears were classified as folded (n=12); constricted (n=7); cryptotia (n=5), and Stahl ear (n=3). Age at the first visit was 1-7 months, and the duration of treatment was 1-13 months. One case of contact dermatitis was observed as a complication. The effects of correction were marked as excellent in 22%, improvement in 56%, and no change in 22% of the cases.
 Our findings suggest that hydrocolloid dressing materials are an effective option for the treatment of congenital auricular deformity.

 Ossifying fasciitis is a relatively rare subtype of nodular fasciitis. Herein, we report a 48-year-old woman presenting with an occipital swelling, which had increased in size over a period of 2 years. Magnetic resonance imaging suggested a benign soft tissue tumor, and resection was attempted under local anesthesia. However, the surgery was not completed due to severe calcification. Computed tomography revealed a calcified tumor, and resection was performed again under general anesthesia. Histopathological examination revealed bone formation, and a diagnosis of ossifying fasciitis was made. As ossifying fasciitis is a reactive proliferative lesion characterized by bone formation, assessment of calcification by computed tomography may aid diagnosis.

 Secondary traumatic optic neuropathy is difficult to treat because there are no clear guidelines for treatment, and it is therapeutically challenging. We report a case of secondary visual impairment that persisted despite treatment for trauma-induced optic neuropathy. A 42-year-old man presented to our hospital following facial trauma sustained in a traffic accident. Computed tomography of the facial bones revealed significant displacement of the ethmoid bone to the left, with compression of the left orbital tissue including the optic nerve. Although the patient suffered an intracranial injury, he exhibited no apparent visual impairment. Therefore, it was decided that he was ineligible for emergency surgery. Unexpectedly, on the second day of hospitalization, the patient developed left visual impairment and was diagnosed with traumatic optic neuropathy. After undergoing facial bone fracture reduction surgery and orbital tissue compression, he was released postoperatively. Steroids were also initiated as adjunctive therapy; however, he did not recover vision in his left eye.
 Our findings suggest that appropriate selection of timing and treatment method for traumatic optic neuropathy in patients with other trauma-induced injuries is important.

 Bone hemangioma is a rare type of bone tumor. Herein, we report a rare case with multiple occurrences in the zygomatic and frontal bones.
 A 45-year-old woman presented with a smooth subcutaneous mass with elastic firmness and poor mobility in the right lower eyelid and left frontal area. Plain computed tomography of the head revealed two well-defined oval lesions in the right zygomatic and left frontal bones. These lesions had a polka-dot-like high-density area, characteristic of bone hemangioma, extending from the outer plate into the bone marrow cavity. The imaging diagnosis was bone hemangioma, and the patient underwent excisional surgery. Histopathological examination showed a cluster of dilated vascular wall structures within a slightly thickened bone ridge, confirming the diagnosis of bone hemangioma. Although asymptomatic bone hemangiomas can be monitored without intervention, patients may show recurrence after removal; therefore, further surgical removal is recommended.

 Calcified cephalhematoma is a rare condition wherein hematoma that develops between the infant's skull and periosteum due to passage through the birth canal during childbirth is not absorbed spontaneously and remains, subsequently ossifying. Surgical treatment is often chosen to improve the cosmetic appearance or relieve cerebral compression.
 A 4-month-old boy presented to our department with a left parietal mass. We diagnosed calcified cephalhematoma. His family requested surgery to improve his appearance; thus, surgical treatment was performed at 1 year of age. We created a three-dimensional model, performed model surgery preoperatively, and used navigation intraoperatively. These methods facilitated the determination of the surgical site and shortened the operation time.
 One year postoperatively, the cranial morphology is well maintained, and the family is satisfied with the surgery results.
