BACKGROUND Head and neck oncologists are often confronted with the difficult challenge of balancing cancer cure with the preservation of function when deciding the patient's best treatment protocol. This task is especially difficult in cancer of the base of tongue. The purpose of this manuscript is to describe the beavertail modification of the radial forearm-free flap in base of tongue reconst...

A new nematode species, Bursaphelenchus sycophilus n. sp. is described. The species was found in syconia of a fig species, Ficus variegata during a field survey of fig-associated nematodes in Japan. Because it has a well-developed stylet and pharyngeal glands, the species is considered an obligate plant parasite, and is easily distinguished from all other fungal-feeding species in the genus bas...

Migratory birds have been suspected as playing a central role in transmission of various trematodes, but few surveys have been undertaken in the Republic of Korea. In the present study, we describe new fauna of microphallid flukes in Korea. Two species of microphallids were found in the intestines of 2 migratory bird species, namely the red necked stints (Calidris ruficollis) and the terek sand...

The purpose of clinical crown lengthening is to increase the extent of supragingival tooth structure for restorative or esthetic purposes. The present article aims at comparing three different crown lengthening techniques. This study was conducted in department of periodontics. It included 30 patients, 15 males and 15 females. Patients were equally and randomly divided into three groups. Group ...

OBJECTIVE To develop a computational model of cutaneous wound closures comparing variations of the rhombic transposition flap. STUDY DESIGN A nonlinear hyperelastic finite element model of human skin was developed and used to assess flap biomechanics in simulated rhombic flap wound closures as flap geometric parameters were varied. SETTING In silico. METHODS The simulation incorporated va...

The human gene for the recently identified 5-lipoxy-genase-activating protein (FLAP) has been cloned. The gene was isolated from two different genomic libraries and is contained within four overlapping bacteriophage clones. The gene spans greater than 31 kilobases and consists of five small exons and four large introns. Southern blot analysis of human genomic DNA suggests the presence of a sing...

Maxillary reconstruction still remains challenging for surgeons despite the fact that maxilla is a static structure. The correct shape and volume of the reconstruction can guarantee the best result in terms of soft tissue support and functional outcome for the patients restoring three-dimensional support of the mid third. The fibula free flap seems to be the best free flap to apply in this type...

BACKGROUND Tissue expansion is a widely used technique to create skin flaps for the correction of sizable defects in reconstructive plastic surgery. Major complications following the inset of expanded flaps include breakdown and uncontrolled scarring secondary to excessive tissue tension. Although it is recognized that mechanical forces may significantly impact the success of defect repair with...

Introduction. Submammary adipofascial flap (SMAF) is a valuable option for replacement of the inferior portion of the breast. It is particularly useful for reconstruction of partial mastectomy defects. It is also used to cover breast implants. Most surgeons base this flap cranially on the submammary skin crease, reflecting it back onto the breast. The blood vessels supplying this flap are not w...
