12. Basal cell carcinoma Radiation Therapy Postradiation – Note destruction of local structures Patient developed a recurrence several years later requiring extensive resection

22. Mucormycosis and aspergillosis This patient required removal of the orbital contents to control the infection resulting in facial disfigurement.

43. Alterations at Surgery to Enhance the Prosthetic Prognosis – Nasal Defects With ideal defects such as these an excellent cosmetic result can be obtained and the prosthesis will be well retained

53. Alterations at Surgery to Enhance the Prosthetic Prognosis Unfavorable Orbital Defects The lids were retained following orbital exenteration. There is insufficient space for an orbital prosthesis. If an orbital prosthesis is contemplated, they should be removed.

54. Alterations at Surgery to Enhance the Prosthetic Prognosis Unfavorable Orbital Defects This orbital defect was filled with a flap. As a result, there is insufficient space for a prosthesis.

55. Alterations at Surgery to Enhance the Prosthetic Prognosis Unfavorable Orbital Defects The eyebrow has been altered in this patient making it more difficult to restore facial symmetry with an orbital prosthesis

75. Form and Symmetry After recontouring the columella and tucking its margin beneath the tip of nose the appearance of the prosthesis is improved.
