In the surgical treatment of otosclerosis, the coupling between the stapes prosthesis and the long process of the incus is critical. After surgery, connective tissue and mucosa may grow over the coupling area and thereby influence the sound transmission properties of the incus-prosthesis interface. It was the hypothesis of this study that tissue ongrowth in the incus-prosthesis interface has li...

BACKGROUND This study investigated the patient's self-report and clinician's confirmation of tracheoesophageal voice prosthesis leakage patterns (through or around) with or without the cough reflex and whether prosthesis diameter affected the leakage route. METHODS Sixty-six consecutive participants with a total of 200 patient-initiated reasons for prosthesis changes were enrolled prospective...

This report describes a different approach for diminishing the movements of orbital prosthesis during mimic movements and chewing function. Mechanical devices such as magnets are used to enhance the retention in case lack of the implants. However rigid fixation of obturator and orbital prosthesis can result in movements of the orbital prosthesis during mastication. In this case obturator and or...

BACKGROUND Use of the proximal part of the femur in total hip arthroplasty enables preservation of the distal femur for later revisions. To use this advantage, different types of short-stem prosthesis have been developed in recent years. Although cementless hip arthroplasty is not common in the treatment of canine osteoarthritis, the use of cementless short-stems might be an alternative therapy...

In vitro biomechanical analysis after cervical disc replacement (CDR) with a novel artificial disc prosthesis (mobile core) was conducted and compared with the intact model, simulated fusion, and CDR with a fixed-core prosthesis. The purpose of this experimental study was to analyze the biomechanical changes after CDR with a novel prosthesis and the differences between fixed- and mobile-core pr...

OBJECTIVES Secondary tracheoesophageal (TE) puncture standardly involves placement of a catheter at time of TE fistula creation. We explore the feasibility of placement of the prosthesis at the time of TE puncture (TEP) obviating the need for a subsequent procedure to place the prosthesis. We describe the technique and evaluate the success and potential advantages. STUDY DESIGN Retrospective ...

Objectives: This paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. The objective was to control the ankle hysteresis at slow and normal walking speeds. Methods: Inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for...

Introduction: Surgical procedures, especially total laryngectomy, have a profound adverse effect on the patient's physical, functional, as well as emotional health, and strongly decrease quality of life. Tracheoesophageal puncture is one of the most significant method that is widely performed successfully by physicians. Current valve technology enables long expiring duration; however, gen...

OBJECTIVE To compare the hearing results in patients with otosclerosis who underwent a stapedotomy with either a platinum wire prosthesis or a commercially available, heat-activated nitinol stapes piston prosthesis. DESIGN Retrospective medical chart review. SETTING Academic tertiary care medical center. PATIENTS Seventy-nine consecutive patients diagnosed as having otosclerosis who under...

conclusions pc-rplnd is one the major operations in the field of urology, which is associated with significant adjunctive surgeries. in appropriate cases, pc-rplnd was associated with good cancer specific survival in tertiary oncology center. results twenty-one patients underwent bilateral pc-rplnd. mean age was 26.3 years (ranged 16 - 47). mean size of retroperitoneal mass after chemotherapy w...
