patients and methods this retrospective cohort study included 405 renal transplant patients from kerman university of medical sciences hospital, kerman, iran from 2004 to 2010. kaplan-meier method was used to estimate survival rates of patients, and time-dependent cox regression was used to examine the effect of allograft failure on patient survival. results during 4.06 years (median) of follow...

introduction: reconstruction of intraoral soft tissue defects is important in restoring function and esthetic. in large defects, there will be demand for regional pedicle flaps or free flaps. hard palate separates nasal and oral cavities. due to the small surface area between flap and remaining palate after surgical resections, optimal blood supply of the flaps for hard palate reconstructions a...

introduction: the purpose of this study was to evaluate vertical facial and dental changes after orthodontic treatment with extraction of first four premolars, and to find whether long facial height could influence the treatment result. methods: fifty-six orthodontic patients with the minimum age of 15, whose treatment plan involved extracting four first premolars, participated in the study. th...

Several factors including cancer, malformations and traumas may cause large facial mutilation. These functional and aesthetic deformities negatively affect the psychological perspectives and quality of life of the mutilated patient. Conventional treatments are prone to fail aesthetically and functionally. The recent introduction of the composite tissue allotransplantation (CTA), which uses tran...

INTRODUCTION Complex injuries to the central part of the face are difficult to reconstruct with the current plastic surgery methods. The ultimate one-staged approach to restore anatomy and vital facial functions is to perform a vascularized composite allotransplantation (VCA). METHODS A 54-year-old man suffered from a high-energy ballistic injury, resulting in a large central facial defect. A...

background : facial harmony and beauty make people attractive. one of the important parts that has a significant role in esthetics is the position of maxillary and mandibular bones. this study aimed to evaluate the effect of different positions of both jaws on esthetic preferences among health professionals and laypersons. materials and methods : two colored photographs of e profile were select...

  Background :Soft tissue profile can be widely different in various populations. Furthermore, this profile can be also continues to change throughout life. However, there are few studies that quantitatively evaluate the soft tissue profile in Iranian population. In order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissu...

Face expression recognition is useful for designing new interactive devices offering the possibility of new ways for human to interact with computer systems. In this paper we develop a facial expressions analysis and synthesis system. The analysis part of the system is based on the facial features extracted from facial feature points (FFP) in frontal image sequences. Selected facial feature poi...

Primary frontal sinus lymphoma is a very uncommon disease. In all the previously reported cases, the presenting symptoms have been due to the tumor mass effect. We present an unusual case report of an immunocompetent patient who presented with facial palsy, and then progressively developed other cranial nerve palsies over several months. He was later diagnosed with diffuse large B cell lymphoma...
