Osteomyelitis of the frontal bone secondary to frontal sinusitis.

Osteomyelitis of the frontal bone is becoming an increasingly rare complication of frontal sinusitis. We present seven cases that represent the largest series published in the last 50 years. Three cases were associated with intracranial involvement. Osteomyelitis should enter the differential diagnosis when there is a fluctuant swelling on the scalp, or if there is a discharging fistula. Treatment requires aggressive surgery to remove all sequestra in combination with long-term antibiotic therapy. Intracranial complications should be excluded by imaging and treated simultaneously if present.

Epidermoid cyst of the frontal bone masquerading as frontal sinusitis.

Epidermoid cysts occur whenever two epidermal surfaces fuse together during early intrauterine life and an ectodermal implant is retained deep to the surface. They are very slow growing and symptoms may not occur till middle age. The authors present a patient whose symptoms of frontal headache were mistaken for frontal sinusitis for over 10 years. The patient's symptoms were completely relieved by surgical excision of an epidermoid cyst of the frontal bone.

[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).

[Reconstruction of the frontal bone with individual titanium implants after surgical therapy of osteomyelitis of the frontal bone].

Individually prefabricated titanium implants enable the reconstruction of the frontal bone after surgical therapy of osteomyelitis without compromising mechanical stability or aesthetic results. Primarily the infected bone tissue is removed. Helical computed tomographic systems are used for the aquisition of patient data. After being transmitted to a computer aided design system (CAD-system) this data is used for construction of the implant geometry using freeform-surfaces. The outer surface contour is derived from the contours of the bone defect. The completed computer-based implant design is finally transformed into control data to run the milling machine which produces the implant from a block of titanium. Modern industrial CAD/CAM-technology allows standardized prefabrication using data from CT-scans. The precision of all implants was predictable and duration of the reconstructive procedure could be reduced. During postoperative follow-up (5-24 months) no loss of implant or recurrence of the osteomyelitis could be observed.

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.

[Clinical examination in open fractures of the frontal bone].

INTRODUCTION: Fractures of the frontal bone most often occur with injuries: in traffic accidents, at work, at home, falls on stairs or slippery surfaces, in sport accidents, hoof injuries, etc. They are mostly seen within combined injuries, much less often as isolated. METHODS AND RESULTS: There were no patients under the age of 20; two were in their thirties, three each in their forties and fifties, and one patient in his sixties. Sex distribution: seven males and two females. Seven patients were injured in traffic accidents, and two working at home. DISCUSSION: Four of nine X-rays, although technically valid, did not reveal fracture lines on the frontal bones. In these cases the fracture was diagnosed by surgical exploration during the treatment of the soft tissue injuries of the frontal region. We must therefore point to the importance of surgical exploration of each, even the slightest injury of the soft tissues of the frontal region, so that the fractures of the frontal bone are not overlooked. Standard X-rays must be interpreted as a supplementary diagnostic procedure, but cannot be considered as absolutely reliable, since the lines can be obscured due to the thickness of the bone structures. The revision was made via the fronto-orbital passage. The mucosae of the posterior wall was intact in five cases, while four cases had a fracture of the interior wall as well, without dislocation of fragments. We preserved the sinus cavities of five patients with only frontal wall injuries, while obliteration was performed in four cases due to the fracture of the interior wall. CONCLUSION: We have ascertained that standard radiography is an unreliable diagnostic procedure and, especially in case of minor injuries of the frontal bone, surgical exploration of the injured region is an imperative, as the only reliable method of excluding fracture of the frontal bone, and this long-established principle cannot be abandoned in these cases either.

[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.
