Treatment for cases with midface hypoplasia such as Apert syndrome and Crouzon syndrome should aim to achieve well-harmonized occlusion and maxillofacial morphology. To date, orthodontic treatments using Le Fort Ⅲ osteotomy concomitant with Le Fort Ⅰ or Ⅱ osteotomy have been reported. In this paper, we present a case with Apert syndrome treated by...

Sec6 and Sec8, which are components of the exocyst complex, has been concerned with various roles independent of its role in secretion, such as cell migration, invadopodia formation, cytokinesis, glucose uptake, and neural development. Given the vital roles of the exocyst complex in cellular and developmental processes, the disruption of its functi...

Free vascularized fibula flaps are commonly used for mandibular reconstruction. However, when performing mandibular reconstruction using such flaps, it is necessary to consider the patient's general condition or tumor prognosis. From September 2009 to November 2013, mandibular reconstruction was performed on 25 patients in the Division of Dentistry...

Primary intraosseous squamous cell carcinoma is a rare jaw bone tumor defined as squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa and developing from residual odontogenic epithelium or from an odontogenic cyst or tumor. Solid type of this tumor arising in the maxilla is an even rarer presentation, be...

Unlabelled: The present report describes the application of a miniplate in the hard palate of a 36-year-old patient with a large anterior maxillary defect. The combination of orthodontic elastics with a titanium miniplate improved the stability of the prefabricated prosthesis. This structure retained the ointment gauze covering the wounds and main...

Myoepithelioma is a rare form of salivary gland tumor composed entirely of myoepithelial cells. This tumor was formerly considered to be a subtype of pleomorphic adenoma; however, in the 1991 World Health Organization classification, it is listed as an independent entity. The most favorable site of occurrence of myoepithelioma is the parotid gland....

Jeune syndrome, or asphyxiating thoracic dysplasia, is an autosomal recessive osteochondrodysplasia. Four forms of Jeune syndrome have been proposed: lethal, severe, mild, and latent. In the severe form, respiratory failure leads to death in early infancy. We present 2 cases of a mild variant of Jeune syndrome in a 14-year-old girl and her 9-year-o...

An 11-year-old boy with congenital radial head dislocation experienced painful snapping of his left elbow upon movement. He had no previous history of trauma. A plain radiograph of his left elbow showed anterior dislocation of the radial head and flexion deformity of the hypoplastic radial neck. Arthroscopy showed that the snapping of the elbow occ...

We describe a male neonate with congenital nasal pyriform aperture stenosis (CNPAS) with autosomal aberration. He was born at 38 weeks and 5 days gestation with a birth weight of 2,760 grams. The Apgar score was eight. He was the product of a normal pregnancy and delivery with no history of illness or exposure to teratogenic agents. He had congenit...

We describe the case of a newborn boy with acrosyndactyly and bilateral cleft lip. At birth around the distal of the affected fingers of the patient, strangulated living tissue was found. At 3 weeks of age, an infant was referred for evaluation of bilateral cleft lip and palate and an acrosyndactyly of the left hand. He was the first child of healt...

Five patients were reported in our congenital anomaly registry who had six hands in total with muscular hyperplasia, aberrant muscles, ulnar drift of the fingers in the metacarpophalangeal (MP) joints, flexion contractures of the MP joints, and enlargement of the metacarpal spaces. Thirty patients with unilateral involvement of this condition have...

Three previous studies have investigated the long-term outcome of radial osteotomy in the treatment of Kienböck disease. However, none used patient-based assessment. The purpose of this study was to investigate the long-term clinical and radiographic outcomes of this osteotomy, including the subjective evaluation of the patient with use of the Disa...

Central polydactyly, syndactyly, and cleft hand are categorized separately in the International Federation of Societies for Surgery of the Hand classification. However, some investigators have proposed that these malformations should be classified into a single category: abnormal induction of finger rays. In this article, we report 5 hands with cen...

De Quervain disease is caused by a stenosing tenosynovitis in the first dorsal compartment, and the main aetiology is extensor pollicis brevis (EPB) tenosynovitis. We encountered three cases in which EPB tenosynovitis was absent and abductor pollicis longus (APL) tenosynovitis was confirmed during operation. In the treatment of de Quervain disease,...

The aim of this study is to assess the postoperative outcome of the two reconstruction methods using both a free jejunal graft and a venous-reconstructed gastric tube or a gastric tube alone after total pharyngolaryngoesophagectomy. We reconstructed the pharyngoesophagus using both a free jejunal graft and a gastric tube in 5 cases (JG group), incl...

We describe a 5-year-old girl with features resembling Trichorhinophalangeal syndrome, type I (sparse scalp hair, bushy eyebrows, bulbous nose, long philtrum, cone-shaped epiphyses, clinobrachydactyly, epiphyseal changes in the femoral head and short stature), and appendicular exostoses similar to trichorhinophalangeal syndrome, type II. However, d...

Whether trigger thumb is congenital or acquired remains controversial. The purpose of this study was to identify whether trigger thumb is present at birth and to clarify whether trigger thumb represents a developmental condition. We examined 1,116 babies born at Yamagata Prefectural Nihonkai Hospital within 14 days after birth. All patients were ex...

SUMMARY Purpose: The purpose of this study is to propose a new classification for congenital longitudinal deficiency.Methods: Clinical cases and experimentally induced congenital limb anomalies by using busulfan were analyzed. Results: In radial and ulnar deficiencies, abnormalities occur in the hand, forearm and/or the elbow. The cause of missing...

Oculocutaneous albinism (OCA) is a complex genetic disease with great clinical heterogeneity. Four different types of OCA have been reported to date (OCA1, OCA2, OCA3, and OCA4). MATP was recently reported in a single Turkish OCA patient as the fourth pathological gene, but no other patients with OCA4 have been reported. Here, we report the mutatio...

Although abdominal perforator flaps based on a cutaneous branch of the deep inferior epigastric artery (DIEP flaps) have many advantages, preparing these flaps is technically difficult and requires great skill, especially as the portion of the artery running under the anterior rectus abdominis sheath must be operated upon "blind". To allow easier p...

SUMMARY Purpose: The purpose of this study is to report results of pollicization for congenital hypoplastic thumb.Method: Ni- neteen patients 24 hands with congenital hypoplastic thumb have been treated with pollicization and followed up for more than 2 years. In these cases, the right hand was affected in 10 cases, the left in 4 and both hands in...
