Wagner, who introduced a general surgery called temporary or osteoplastic resection of the skull, suggested that temporary resection of the eye socket is also possible by removing a wedge-shaped section of the ocular margin and the adjacent bones of the face. At the same time and independently of him, the famous Swiss surgeon R. Krnlein, for the removal of the dermoid cyst lying behind the eye socket, opened up access to it through the resection (temporary) of the external ocular roof. He removed the tumour and left the eyeball in place.</p>Kazan Medical archiveКазанский медицинский архив
