The foramen of Huschke, or foramen tympanicum, is a developmental defect in the bony part of the external auditory canal (EAC) due to a defect in ossification of normal bone in the first 5 years of life. Seen in the anteroinferior part of the EAC, it can be asymptomatic or present with salivary discharge into the EAC during mastication or as soft tissue swelling in the EAC in the absence of any...

Objective: The aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy.Methods: A Siemens Primus linear accelerator and a phantom were simulated using MCNPX Monte Carlo code. In a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. The tissues included muscle (ske...

A 32-year-old male came to the emergency room with a crescentric 4x11 cm tissue defect at the right temporo-parietal region. Brain tomography showed a tissue defect in the right parietal region but bone integrity was preserved. A free flap procedure was performed to protect the cranial bones. Two months after discharge from the hospital, he presented with a draining dirty wound that appeared ne...

Reconstruction of large abdominal wall defects is a challenging problem. Various reconstructive techniques have been described in the surgical literature each with its advantages and disadvantages. In this report we describe our experience in treating a patient with large abdominal wall defect by staged abdominal wall reconstruction utilizing prosthetic mesh in conjunction with tissue expanders...

tissue-engineered gingival graft was used for regenerating facial gingiva around an implant at lower left first premolar area with insufficient attached gingiva. engineered gingival graft was produced by mixing 250 ml bovine skin collagen with 250 ml nutritional medium containing human gingival fibroblasts (2×105). 3 months post-surgery, there were gains in the attached gingiva compared to pre-...

INTRODUCTION Tibia fracture caused by high velocity missiles is mostly comminuted and followed by bone defect which makes their healing process extremely difficult and prone to numerous complications. CASE OUTLINE A 34-year-old male was wounded at close range by a semi-automatic gun missile. He was wounded in the distal area of the left tibia and suffered a massive defect of the bone and soft...

BACKGROUND AND AIM: Maxillofacial defects due to malignant or benign tumors or congenital defects often result in complications such as the impairment of facial aesthetic, mastication, speech, and swallowing. Remedy of these defects, especially in a dentate patient is an important challenge in prosthodontics. Maxillectomy can lead to severe anatomical changes f...

BACKGROUND The standard methods for reconstruction of soft tissue defects in the leg include gastrocnemius flap for proximal third defects, soleus flap for middle third and free flap in the distal third. However, there are problems with the use of free flap, like increased operative time, damage of major vessels and the need for experienced microsurgeon. METHODS This prospective study was und...

BACKGROUND Osteoradionecrosis is the most dreadful complication after head and neck irradiation. Orocutaneous fistula makes patients difficult to eat food. Fibular free flap is the choice of the flap for mandibular reconstruction. Osteocutaneous flap can reconstruct both hard and soft tissues simultaneously. This study was to investigate the success rate and results of the free fibular flap for...

Large soft tissue defects involve significant tissue loss, requiring surgical reconstruction. Autologous flaps are occasionally scant, demand prolonged transfer surgery, and induce donor site morbidity. The present work set out to fabricate an engineered muscle flap bearing its own functional vascular pedicle for repair of a large soft tissue defect in mice. Full-thickness abdominal wall defect...
