Otologists who prefer intact canal wall surgery for removal of cholesteatoma recognize a 12.25% return rate. Revisions often indicated to correct hearing loss are frequently negative for recurrent cholesteatoma. To determine the reliabiity of a noninvasive method of diagnosing recurrent disease and possible complications, 40 patients previously operated on for cholesteatoma using the intact canal wall technique were scanned with a General Electric 8800 scanner. Second procedures were performed on 24 patients and findings compared with preoperative film interpretations. Scans correctly predicted no significant masses in 6 patients and cholesteatoma recurrence in 11; the remaining 6 with diffuse soft tissue changes were incorrectly diagnosed. Focal areas of bone erosion were detectable in 3 cases, indicating active or potential complications. Scans were reliable in detecting cholesteatoma depending upon the pathology.

The tympanic membrane forms an impenetrable barrier between the ear canal and the air-filled middle ear, protecting it from fluid, pathogens, and foreign material entry. We previously screened a phage display library and discovered peptides that mediate transport across the intact membrane. The route by which transport occurs is not certain, but possibilities include paracellular transport through loosened intercellular junctions and transcellular transport through the cells that comprise the various tympanic membrane layers.

Objectives: Femtosecond laser image guided high precision trabeculotomy (FLigHT) is a novel open-angle glaucoma treatment. The procedure non-invasively creates aqueous humor (AH) drainage channel from the anterior chamber (AC) to Schlemm's canal (SC) through the trabecular meshwork (TM) to decrease intraocular pressure (IOP). The purpose of this study was to develop a 3D finite element model (FEM) of the FLigHT procedure and to simulate clinical results for different drainage channel cross-sectional areas.

Background: Endodontic file fractures are common complications of root canal treatment, and requires removal via specialized techniques such as endodontic microsurgery when the file beyond the apical foramen. It is often challenging to precisely and minimally remove a fractured file. Recently the use of dental autonomous robotic system (ATR) has shown promise in precisely and minimally in dental surgery.
