An approach for the correction of cryptotia using a superiorly based superficial mastoid fascial flap and a skin paddle is introduced. The buried portion of the auricle was exposed through an incision made along the upper part of the helix, followed by an appropriate correction of the deformed cartilage. Protrusion of the upper portion of the auricle was accomplished using anchoring sutures. A ...

SUMMARY The reconstruction of mandibular defects has always been of great concern, and it still represents a challenge for head-and-neck reconstructive surgeons. The mandible plays a major role in mastication, articulation, swallowing, respiration, and facial contour. Thus, when undertaking mandibular reconstruction, restoration of both function and cosmetics should be considered as the measure...

Contour line is the main linear feature on topographic maps. Extraction of contour lines is tedious and time-consuming process, and is still an interesting problem. A novel method for extraction of contour lines from paper-based topographic maps is presented in this paper. In our approach, we firstly segment color topographic maps for achieving the binary image of brown color contour lines. The...

purpose: to evaluate the diagnostic signs, intraoperative complications and postoperative outcomes in children with congenital cataract and pre-existing posterior capsule defect (ppcd). methods: this interventional case series was conducted on 14 eyes of 7 patients who underwent lensectomy-anterior vitrectomy for congenital cataract with ppcd. all children had bilateral cataract. preoperative d...

Active contour is an effective technique for object boundary extraction in biomedical images such as blood vessel tracing or optic disc extraction in retinal images. The traditional serial realization of contour finding needs considerable processing time. This paper presents a parallel realization of the active contour model to speed up the contour convergence process. The initially drawn conto...

We present a method for the semi-automatic, model-driven segmentation of the Left Ventricle (LV) in cardiac SPECT data. Accurate segmentation of the LV allows computation of quantities that describe the degree of a perfusion defect. A 3D surface is initialised in the dataset and deforms to fit the shape of the LV. The model is chosen from a small number of prototypes. The behaviour of the dynam...

An unusual patient is described in whom electrophysiological studies strongly suggest the occurrence of Mahaim conduction. The patient whose electrocardiogram previously showed a left anterior hemiblock pattern then developed advanced atrioventricular (AV) block (AH block). Beats conducted through the atrioventricular node always had a short HV interval (20 ms) and QRS complexes of left anterio...

UNLABELLED Large defects of the nasal tip with exposure of the underlying cartilage pose a significant reconstructive challenge to the plastic surgeon. OBJECTIVE This article presents a case of a large nasal tip defect following basal cell excision that was successfully treated with Integra bilayer wound matrix and skin grafting. METHODS Following tumor excision, meshed Integra bilayer woun...
