Although osteomas of the paranasal sinuses are slowly growing bony benign neoplasms, they can cause very important orbital or neurological complications. A 58 year old man's osteoma with sinusitis, abscess and proptosis is reported. A review of the literature is presented and the importance of CT scanner, to appraise the enlargement of the tumor and so to select the best surgical approach, is defined.
Ceruminoma is a rare form of tumor in man. Most of them are found in the external ear, rarely in the middle ear. The authors review the relevant literature and report a case of ceruminal adenoma arising in the middle ear. The prognosis of these tumors is relatively bad because of their potential malignancy and the tendency for recidivation. Recommendations for treatment are deep excision, postoperative irradiation in malignant types and regular follow-up visits.

The authors related a case of high osteoplasic tracheopathy in a women, 79 years old. The semiology and the different etiopathogenic theories are reviewed. The affection is characterized by the presence in the tracheal sub-mucosa or sometimes the bronchial sub-mucosa of cartilagenous and often bony spaces, which cuases the stenosis of the respiratory lumen. In this related case, the lesions are situated at the level of a tracheal segment compressed by an important goitre. It seems to be caused by a local metaplasia induced by the compression.
