This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis is done using COMSOL Multiphysics. The maximum applied acceleration was considered 1g. Human temporal bones a...

Replacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the...

The fabrication of any extra oral maxillofacial prosthesis presents the prosthodontist with several phenomenal challenges. Foremost among them is the flawless recreation of the same anatomic form that was present preoperatively. The Challenge of recreating preoperative anatomic contour is sometimes complicated by the absence of a preoperative record. This is common when the loss is congenital o...

STATEMENT OF PROBLEM Although surgical reconstruction is the treatment of choice for auricular deformities that result from hemifacial microsomia, the implant-retained auricular prosthesis must be considered when surgical reconstruction is not possible. The competent and successful practitioner should be knowledgeable of the nature of this congenital disease. PURPOSE This article reviewed the...

Sculpting a wax ear cast for use when making a definitive prosthesis for a patient who has had auricle ablative surgery, is challenging. It requires a skilled anaplastologist along with complex instrumentation able to perform facial laser scans and reproduce anatomic details. The aim of this article is to present a technique to create a cast by laser scanning a stone cast of the existing ear. A...

Numerous attempts to deal surgically with otosclerosis were made before the current method of stapedectomy with stapes prosthesis was established. We report a case with unique CT findings of a patient who underwent fenestration surgery for otosclerosis in the early 1940s. Recognition of this old surgical procedure on the imaging scans may avoid misdiagnosis of labyrinthine fistulae or middle an...

Currently, patients with external ear deformities rely on hyaline cartilage grafts or silicone prosthesis to provide them with adequate external ear reconstruction. Scaffold-free auricular tissue engineering provides a means of creating patient specific cartilage constructs solely using their own cells, ensuring biocompatibility, long term stability, and reduced morbidity. Here, we have develop...
