Congenital Aural Atresia- Our Experience with Three Distinct Cases
Congenital aural atresia, a rare entity, may be accompanied with variations in course of facial nerve and congenital cholesteatoma. In the present study, we describe three distinct cases of aural atresia, with successful management, according to the extent of atresia. Management of atresia is essentially a team work, comprising of otologist, plastic surgeon, radiologist and paediatrician, thus ...
متن کاملThe "boomerang" malleus-incus complex in congenital aural atresia.
"Boomerang" malleus-incus fusion deformity is identified on axial high-resolution CT in a subset of patients with congenital aural atresia, and it is associated with an absent incudostapedial joint and stapes capitulum and attachment of the incus to the tympanic segment of the facial nerve canal. Twelve patients with this deformity were identified on a retrospective review of imaging from a coh...
متن کاملAccelerating Virtual Surgery Simulation for Congenital Aural Atresia
In this paper, we proposed a new efficient implementation for simulation of surgery planning for congenital aural atresia. We first applied a 2-level image segmentation schema to classify the inner ear structures. Based on it, several 3D texture volumes were generated and sent to graphical pipeline on a PC platform. By exploiting the texturingmapping capability on the PC graphics/video board, a...
متن کاملComputer-aided virtual surgery for congenital aural atresia.
HYPOTHESIS Computer-enhanced three-dimensional (3D) computed tomography (CT) provides accurate spatial representation of the complex surgical anatomy of congenitally atretic ears, and is superior to conventional CT for surgical planning. BACKGROUND The surgical repair of congenital aural atresia is challenging. Conventional CT, routinely used for surgical planning, is limited in its ability t...
متن کاملComputer aided surgical planning for congenital aural atresia
We have designed and implemented a prototype system to aid in the surgical repair of congenital aural atresia. A two-level segmentation algorithm was first developed to separate tissues of similar intensity or low tissue contrast. Then an interactive visualization modular was built to display the labeled tissues. The system allows a 3-stage interactive planning in which positioning, marking and...
