Cranioplasty by means of molded polymethylmethacrylate prosthetic reconstruction after radical excision of neoplasms of the skull in two dogs

J Am Vet Med Assoc. 2003 Jul 1;223(1):67-72, 59. doi: 10.2460/javma.2003.223.67.


Two dogs with osteoma or multilobulated tumor of bone of the skull were treated with large en bloc resections. The resections resulted in exposure of the brain above the horizon line of the remaining calvarium; in 1 dog, the removal of the dorsal orbital rims also exposed both orbits dorsally. Protection of the brain and exposed tissues and restoration of the cosmetic appearance of the skull were attempted by use of molded polymethylmethacrylate prosthetic reconstruction of the calvarium. The technique described involves cranioplasty by use of a preformed molded polymethylmethacrylate implant. Such prosthetic cranioplasty may benefit dogs undergoing radical excision of extensive tumors, and the usefulness and potential complications of its application are discussed.
