Successful replacement of the sound conducting mechanism of the ear has been hampered by infection, perforation, prosthesis instability and extrusion. In this animal study on thirty rats a silicone prosthesis was inserted between two layers of fascia as a total replacement of the tympanic membrane and ossicular chain. After four months the graft was found to be intact without evidence of infection or extrusion in all but one of the 30 rats. These results justify a trial of a similar silicone prosthesis in humans.

Comparative Evaluation of the Dimensional Accuracy of Silicone-Based Putty Reline Impressions with Different Spacer Acquisition Techniques in Fixed Partial Dentures.

BACKGROUND A tooth preparation's clinical requirements and geometric configurations should take precedence over material characteristics when advocating for putty reline impression techniques for permanent restorations, since they require a technically sensitive spacer for light body elastomer. We evaluated the linear dimensional accuracy of vinyl polysiloxane-based putty reline impressions with different spacer acquisition techniques in short-span and long-span fixed partial dentures (FPD). MATERIAL AND METHODS A typodont tooth set simulated a 3-unit (short-span) and a 5-unit (long-span) FPD.

Background: Penile implant surgery is the standard surgical treatment for end-stage erectile dysfunction. However, the growing complexity of modern high-tech penile prostheses has increased the demand for more practical training opportunities. The most advanced contemporary training methods involve simulation training using cadavers, with costs exceeding $5,000 per cadaver, inclusive of biohazard fees.

Expiratory central airway collapse is a degenerative tracheobronchial disease that is often overlooked because of its nonspecific clinical features. A man was admitted for evaluation of tracheal nodules. Following bronchoscopic biopsy, a significant increase in airway pressure occurred during anesthesia recovery.

The reverse scan technique offers several advantages, such as improvements of accuracy and visibility of critical anatomical structures, minimizing chair time, and providing better patient comfort. This was a case report successfully employing the reverse scan technique. A 72-year-old male patient desired to restore his teeth in both jaws, as he experienced difficulty eating and had never worn dentures.

We report a case of a woman in her late 40s with a history of breast implant surgery following breast cancer treatment. She presented with asymmetrical breast enlargement, palpable contralateral axillary lymph nodes and cutaneous nodules on both forearms. In addition, imaging evaluation revealed intracapsular implant rupture, ipsilateral internal mammary enlarged lymph nodes and multiple mediastinal lymphadenopathies.
