Experimentally transposed homograft ossicles in rats showed behaviour less stables than autografts, all being resorbed within 48 weeks. Using information derived from this and other experimental work in both animals and humans it is predicted that homografts will be unstable in humans in the long term.

Mastoid obliteration can be performed after canal wall down (CWD) mastoidectomy with various materials. Homologous bone tissue harvested from cadaver donor represents a feasible option with advantages. The purpose of the study is to describe the case of a patient diagnosed with middle ear cholesteatoma treated with mastoidectomy of the CWD and mastoid obliteration with homologous freeze-dried corticocancellous bone particulate in the Cittadella Hospital Ear, Nose, Throat (ENT) unit.

Chronic Otitis Media is a global health problem causing significant morbidity of life. Various medical and surgical treatment modalities are being used for the treatment of Chronic Otitis Media. Surgical treatment is the definitive option which includes different surgical procedures, all of which have been designed to attain the same goals of eradicating disease and achieve a safe and dry ear with closure of tympanic membrane perforations.

Introduction: The tactics of treating patients with retraction pockets of the tympanic membrane is still debatable. When choosing surgical treatment, preference is given to the removal of the retraction pocket with simultaneous reconstruction of the posterior-upper wall of the external auditory canal (retraction area) with a cartilage or fascial flap, autologous bone, or a combination of the above tissues. Considering the well-known negative aspects of the use of all the mentioned grafts, there is a need to find new types of tissues to strengthen the retraction pocket.

Objective: Surgical repair of tympanic membrane perforations has been traditionally performed with autologous soft-tissue grafts with high success rates. Newer allografts such as porcine small intestine submucosa (pSIS) have been employed as alternatives to minimize donor morbidity and surgical time, and in cases where autologous tissue may not be available. The comparative anatomic and audiometric success rates of these tissues is still unclear.
