Baro Baneswar | Rabha Gunamani | Sarma Tapan

Abstract: The temporal bone is a valuable piece of resource for the purpose of study of ear diseases and to teach its anatomy. Dissection of the middle ear is a complicated procedure. The most commonly used method is the Piece Meal Removal of the bone or chipping/snipping off the bone into pieces and the block method of harvesting human cadaveric temporal bones. Many of the medical professionals have ever seen the real ossicles in their life time. The methods adopted earlier were intricate and time consuming. The present study was conducted in the department of Anatomy, Assam Medical College, Dibrugarh, Assam in the year 2018 on 20 intact temporal bones of 10 base of skull. The jeweler’s cut method a new innovative method was performed and we tried to evaluate the efficacy and reasonability of the technique. By this method the temporal bone can be exposed to see the middle ear cavity as like the pictures in the textbook of Anatomy. The jeweler’s cut method proves to be the scientific, accurate and least destructive method of dissection as compared to the traditional methods of piece meal removal of bone as chipping away the roof (tegmen tympani) or snipping off done for exploring the middle ear cavity and mastoid air cells.
