METHODS USED IN OBTAINING AND PREPARING 

 SPECIMENS 



(a) Method Used in Removing the Nasal Accessory 

 Sinus Areas en Masse at Postmortem Examinations With- 

 out Producing Marked Disfigurement of the Face. The 

 skull having been opened by the usual circumferential saw- 

 cut and the brain removed, further detach the skin and sub- 

 cutaneous structures from the frontal area to the level of 

 the nasion. With the saw make in the sagittal direction 

 cuts through the frontal bone just lateral to each supra- 

 orbital notch, and extending through the supra-orbital 

 plates. Remove with bone-forceps the portion of supra- 

 orbital plates lying lateral to the sagittal cuts, thus obtaining 

 room to detach the eyeballs posteriorly and turn them for- 

 ward. Dissect the skin and muscles from the nasal, lacrimal, 

 and maxillary bones; then from the anterior end of the nasal 

 bones cut through the nasal septum and lateral nasal 

 cartilages to the anterior nasal spine of the maxilla. With 

 a chisel cut through the basi-occipital bone; thence lateral 

 to the body of the sphenoid extend the cuts to the spheno- 

 maxillary fissure. With a saw or with a costotome cut 

 through the maxillary processes of the malar bones and 

 remove the specimen en masse. 



To reconstruct the face, fill the oral cavity and the space 

 previously occupied by the specimen with cotton packed 

 firmly to the level of the orbital floor. Turn the eyeballs 

 back into place, and pass two sutures through the sub- 

 is
