    The problems faced by patients with cleft lip and/or cleft palate are extremely multifaceted: they include aesthetic concerns, problems with milk consumption, speech impediment, ear disease, discrepancy in the upper alveolar arch, malocclusion, maxillary retrusion, mastication disorder, sever dental caries, and psychophysiological problems. Furthermore, such patients require long-term post surgical follow-up. In such cases, interdisciplinary care is required in order that optimal functional and esthetic results can be obtained. In addition, such care should be systematic and directed by consistent policy.
    Primary treatment through interdisciplinary care is the most importance, as primary lip surgery will influence aesthetic outcomes throughout the patient’s lifetime, and primary palatoplasty for infants will affect speech function for life. Recently, cleft teams have been joined by midwives, counselor and clinical geneticists, reflecting a new current in primary treatment. However, the basic concept and need of interdisciplinary cooperation remain the same.
    The purpose of this paper is to describe the general approach to and our policy on primary therapy for cleft lip and/or cleft palate, and report a part of the questionnaire-based survey and analysis for current trends in interdisciplinary care in Japan conducted by the Japanese Cleft Palate Association.

    Traumatic optic neuropathy (TON) involves various grades of vision loss or deterioration without ocular injury following facial trauma. Causes of TON include direct optic nerve injury, fractured bone fragments, optic nerve ischemia, and optic nerve compression by hematoma or edema. We treated a 78-year-old woman with impaired left visual acuity caused by optic nerve compression by the fragments of a left zygomatic bone fracture.After detailed optic examinations by an ophthalmologist and neurosurgeon in the departments of ophthalmology and neurosurgery, open reduction and fixation were performed about 27 hours after injury. The patient gradually recoved from TON and had no severe complications after the operation. Although the management of TON remains controversial, many reports suggest that there is no significant difference in outcomes between surgical treatment and non-surgical treatment. However, zygomatic bone fracture with clinically significant dislocation or nerve impairment is generally an indication for surgical reduction. Since few reports have documented exacerbation of visual acuity after open reduction and fixation, operation should not be delayed in patients with no systemic problems. Consideration of optic functions and consultation with related departments are essential when treating patients with mid-facial fractures.

    Hereditary angioedema (HAE) causes life-threatening laryngeal edema. The attack can be triggered,in general, by trauma, drugs, and infection. The risk after dental treatment and oral surgery is higher than that after other surgical procedures.We report on a 41-year-old woman with psoriasis arthropica and HAE who required tooth extraction and a cystectomy. To prevent angioedema, we injected tranexamic acid and C1 inhibitor before surgery. She underwent tooth extraction and a cystectomy under intravenous sedation. She was closely monitored during the night and was discharged from the hospital on the 4th day after operation. The patient received surgery successfully without any complications.The use of tranexamic acid, C1 inhibitor, and intravenous sedation is effective for preventing attacks of angioedema in HAE patients.

    Ameloblastic fibrosarcoma is a very rare malignant odontogenic tumor. Ameloblastic fibrosarcoma consists of benign epithelial components with the same features as those of ameloblastic fibroma, as well as malignant mesenchymal components. We report a case of ameloblastic fibrosarcoma arising in the mandible. A 32-year-old woman underwent left hemimandiblectomy, supraomohyoid neck dissection, and reconstruction. Immunohistochemically, the Ki-67 labeling index was low in the epithelial components of the tumor (1.6 %), but high in the malignant mesenchymal components (19.8 %). After operation, adjuvant chemotherapy was administered. There was no recurrence or metastasis 3 years after surgery.
