The anterior fontanelle is fibrous connective tissue continuous with frontal, coronal, and sagittal sutures. Its premature closure or narrowing may indicate craniosynostosis, and patients are often referred from obstetric or pediatric departments. Here, we report a retrospective observational study, based on medical records of patients who were referred with the complaint of premature closure or narrowing of the anterior fontanelle. The study subjects were 41 patients who visited our plastic surgery or neurosurgery department with the complaint of premature closure or narrowing of the anterior fontanelle between April 1, X year and September 30, X+11 year and were followed-up for more than 6 months. There were 26 boys and 15 girls. The ages of patients ranged from 1 to 14 months, with an average of 5.8 months. All patients underwent X-ray examinations, and CT and MRI were added as necessary. Seventeen patients（41.5%）were diagnosed with craniosynostosis, and treatment was performed for 14 patients（34.1%）. Surgery is often carried out by the age of 1 year, but even in cases where it is not conducted, follow-up observation until the age of 6 years is considered necessary.

　　Photoimmunotherapy has recently been applied in the treatment of unresectable, locally advanced, or locally recurrent head and neck cancer. One of its associated adverse events is skin damage, and the development of fistulas and ulcers of skin and mucosa after photoimmunotherapy has been reported. Herein, we report a case of oral maxillary cutaneous fistula caused by photoimmunotherapy after recurrence of maxillary cancer following radiotherapy, with concomitant intra-arterial cisplatin administration, tumor resection, and reconstruction. The fistula was successfully closed with free anterolateral thigh flap reconstruction. Although the ulcer and fistula in this case were directly caused by photoimmunotherapy, we also considered the effects of radiotherapy during the previous treatment process when reconstructing the free flap in terms of the debridement technique, reconstruction approach, and wound healing. More than one year has passed since surgery and there has been no fistula or tumor recurrence.

　　Cleft lip and palate are common congenital anomalies of the maxillofacial region. They often impair oral functions such as feeding, swallowing, and articulation, as well as affect esthetics and psychosocial well-being. Early, multidisciplinary intervention and continuous care from a specialized medical team are important. However, in rare cases, patients may reach adulthood without having received timely or appropriate treatment.
　　This case report describes a 22-year-and-3-month-old female patient with untreated bilateral cleft lip and palate since early childhood, presenting with severe maxillary constriction, alveolar bone defects, malocclusion, and significant esthetic and psychological problems. Pre-surgical orthodontic treatment required approximately 15-mm maxillary expansion in the canine region, which was successfully achieved despite the patient’s age. Subsequent alveolar bone grafting resulted in successful bone bridge formation. This grafting enabled postoperative orthodontic treatment, resulting in favorable tooth alignment and occlusal function.
　　Comprehensive interdisciplinary management led to marked improvements in oral function, esthetics, and psychological well-being, with marked patient satisfaction.

　　Osteoma is a benign tumor characterized by slow proliferation of compact and cancellous bone. Reports of osteomas originating in occipital bone are rare. We report a case of solitary osteoma arising near the foramen magnum. The patient was a 42-year-old woman who presented to our department with a palpable hard mass in the right occipital region, accompanied by neck pain and headache. Non-contrast computed tomography（CT）revealed a bony tumor protruding from the occipital bone toward foramen magnum. Contrast-enhanced CT demonstrated that the shortest distance between the osteoma and the right vertebral artery was 3.0 mm. The tumor was surgically resected, and histopathological examination confirmed the diagnosis of osteoma. At 6 months postoperatively, both the neck pain and headache had resolved, with no evidence of recurrence. To our knowledge, there are no reports in the literature of an osteoma arising adjacent to the foramen magnum. In the present case, the tumor was located near the foramen magnum, where several critical neurovascular structures pass. Considering the patient’s symptoms and potential for symptom progression or increased surgical risk with continued observation, early surgical intervention was selected. Postoperative symptom relief in this case suggests that, even for osteomas, thorough neurological assessment prior to surgery is essential when the lesion is located near critical anatomical structures.
