The successful employment of free fat grafts elsewhere in the body has suggested this method of closing postauricular openings resulting from mastoid operations. Dr. Wells P. Eagleton1 used bone chips during the war as a filling substance in closing old mastoid wounds, and it was due to his proposal that we first used fat for this purpose.
Fat placed in the orbit after the enucleation of an acutely infected eye shows great resistance to infection, and will practically always remain, in part, to form a satisfactory stump. Depressed and adherent scars may be excised and the cut edges elevated into proper position by the insertion of fat beneath the skin.
It is a clinical fact that skin heals more readily where a layer of adipose tissue is present under the corium. The experiments of Hartwell2 demonstrated the importance of fat in the healing of surgical wounds.
