[Aneurysmal bone cyst of the frontal bone (author's transl)].

A six year-old boy. He complained of a swelling of the left forehead since October of 1971, the region of his upper eyelid has then been gradually swollen. He was admitted to our institute on the 24th of February, 1973, without the past history of head trauma. We found that the swollen region had a diameter of about 4 centimeters covered from the left upper eyelid to the forehead with a slight tenderness on pressure. We had no neurological findings. According to the results of skull X rays, the superior margin of left orbit and zygomatic process of frontal bone were swollen and like honey combs. An irregular, long and narrow osteolytic legion was found, which was about 4 centimeters long and 5 centimeters wide. According to the results of the left selective external carotid angiography, after injection of 60% Urografin, for more than 2.5- 10 seconds, at the left frontal bone an abnormal shadow (patchy contrast filling) was noted, which was about 4 centimeters long and 5 centimeters wide. After the direct injection of Urografid into the lesion, the cyst of one centimeter long and 3 centimeters wide was observed at the zygomatic process of the frontal bone. Operation was performed to excise the outer plate of the swollen bone and to curette the lesion after the ligature of the left external carotid artery. Histological examination showed many blood lakes and some multinuclear giant cells in the specimens and we diagnosed it was an aneurysmall bone cyst. This case is the first one of aneurysmall bone cyst confirmed by the selective external carotid angiography and the direct puncture of lesion.

Frontal bone defect with frontal sinus mucopyocele.

For this patient's treatment, all three consultants advise against the Lynch-type frontoethmoidectomy procedure, with or without mucoperiosteal flap reconstruction of the nasofrontal duct. Treatment plan: Culture and sensitivity of pus; 2-3 weeks of intravenous antibiotics followed by osteoplastic flap fat obliteration of frontal sinus; delayed defect repair with methyl methacrylate (Montgomery). Trephination followed by treatment with local and systemic antibiotics (Donald); removal of infected bone and soft tissue (sinus collapse) and delayed defect repair in 6-12 months (Donald, Calcaterra) with metylmethacrylate (Donald) or in situ cured silicone elastomer (Calcaterra).

Aneurysmal bone cyst of the frontal bone.

Aneurysmal bone cyst rarely affects the skull. We report two cases of aneurysmal bone cyst of the frontal bone. One of the cases is associated with pregnancy. The association of pregnancy with aneurysmal bone cyst and enlargement of the aneurysmal bone cyst during the pregnancy have been discussed.

[Surgical treatment of osteomyelitis of the frontal bone and the walls of the frontal sinus].

Having in view observations made during surgical treatment of 21 patients with frontal bone osteomyelitis of traumatic (18 patients) and rhinogenic (3 patients) origin, three varieties of osteomyelitis can be distinguished, viz. osteomyelitis of frontal squama, osteomyelitis of frontal sinus wall, and mixed osteomyelitis involving nasal bones. Three therapeutic approaches are recommended: closed healing of the wound after dissecting the fistula and removal of osteomyelitic bone lesions, drainage of frontal sinuses via the frontonasal anastomosis, and tamponade of the cavity, that developed after the resection of the pathological focus, with the host muscle tissue. In advanced osteomyelitis of the frontal sinus walls, preference should be given to the neurosurgical approach with a wide revision of the pathological focus, removal of the mucosa, suppurative epidural layers and further formation of an enlarged frontonasal anastomosis and prolonged drainage of the cavity for 24 to 30 days. When treating osteomyelitis of frontal squama with its significant enlargement, the most efficient method is tamponade of the cavity formed by the hard membrane, skin and bone with the host muscle. Small osteomyelitic lesions of the frontal bone can be removed by dissecting the fistula, 3-4 day draining and suturing the wound.

Osteomyelitis of the frontal bone.

Osteomyelitis of the frontal bone and its complications remain a diagnostic and therapeutic challenge to the head and neck surgeon. This paper will deal with the etiology, pathogenesis, diagnosis, and treatment of osteomyelitis of the frontal bone, and its complications and sequelae. Special emphasis is placed on techniques for repair of forehead defects.

Chondromyxoid fibroma of the frontal bone.

Chondromyxoid fibroma of frontal bone is a rare lesion. Plain skull films showed a round radiolucent mass with a sclerotic margin. It was dense on plain CT scan and showed no convincing contrast enhancement. MR imaging showed low signal intensity relative to gray matter on T1-weighted image (500/20), isointensity on proton-density image (2000/30), high intensity on T2-weighted image, and marked peripheral enhancement on postcontrast (gadopentetate dimeglumine) study.

Cholesterol granuloma of the frontal bone: CT diagnosis.

Cholesterol granuloma of the frontal bone is a distinct clinical entity. This expanding lesion grows slowly within the diploe of the frontal bone until it extends into the orbit and causes globe displacement. We report the clinical and the CT findings in 11 patients with cholesterol granuloma of the orbit. The CT characteristics of cholesterol granuloma of the frontal bone appear to enable a correct preoperative diagnosis.

[Can one speak of the "recession" of the frontal bone?].

The receding aspect of the frontal bone in Primates and fossil men, comes primarily from the orientation adopted and the nature of the point chosen, the ontogenic shift of which is important. There is a confusion between shape and position notions. A study in the "vestibular" axes demonstrate that the inclination of the squamous portion of the frontal bone is significantly less variable then has been claimed, especially if one considers the endocranium.
