Facial osteomas: fourteen cases and a review of literature

OBJECTIVE

Osteomas are benign tumors that frequently affect the cranio-facial region, especially the temporal bones, jaw and sinus. This lesion very rarely involves the maxillary bones. The aim of our study is to describe our surgical case series and to evaluate the diagnosis and management of peripheral craniofacial osteomas with a review of the literature.

PATIENTS AND METHODS

We retrospectively analyzed a series of 14 patients that underwent surgery for the removal of a cranio-facial osteoma, 10 cases were peripheral osteoma of the lower jaw and 4 were peripheral osteomas of the upper jaw. The 14 patients included 8 females and 6 males, with a mean age of 42 years. The median follow up period was 48 months.

RESULTS

All patients received a total surgical removal and we did not have any intraoperative complications with optimal cosmetic and functional results. Pain resolved in all cases and a single case postoperative dysesthesia occurred. NO recurrence has been detected at last follow-up visit.

CONCLUSIONS

Osteomas must be well identified and differentiated from other solid diseases of the bone and should be treated if symptomatic. The elective treatment is surgical removal, resulting in a complete resolution of the pathology.

The Ilizarov method for the treatment of infected pseudarthrosis of the tibia: our experience in cases with severe lesion of the soft tissues

Between 1985 and 1990 a total of 35 cases of infected pseudarthrosis of the tibia were treated by radical resection of the pseudarthrosis and corticotomy-distraction-compression. In 5 patients there was severe lesion of the soft tissues with extensive loss of substance. It is the purpose of the present study to evaluate the effects of the use of this method on lesions of the soft tissues in these 5 patients.

Lumbosacral monolateral dislocation

The authors describe a case of traumatic monolateral dislocation of L5 on S1. It is a very rare lesion which involves serious diagnostic and therapeutic problems. Surgical treatment constituted by reduction and stabilization alone can obtain stable correction of the deformity and complete functional recovery.

Surgical treatment of poliomyelitic scoliosis

Between 1968 and 1973 forty nine patients suffering from poliomyelitic scoliosis were treated surgically at the Rizzoli Institute. They were due to asymmetrical paralysis and contracture in the muscles of the trunk and limbs. Associated pathological conditions were found, such as pelvic obliquity, and vascular and trophic changes due to ganglionic lesions. The differing incidence and combination of these factors gave rise to various clinical types of spinal deformity. The average severity of curve was 39 degrees, the localisation was predominantly central, the average extent was ten vertebrae, and there was a marked predominance of right convexity (twenty nine out of thirty six). The rate of progression was maximum during puberty and almost negligible after bony maturity. It was greater in males and was unfavourably affected by the severity and asymmetrical distribution of the paralysis, by the early appearance of the disease, by high localisation of the deformity, and by the erect posture in patients who were ambulant. The most frequent visceral complications were in the respiratory system (ten patients with a deficit over 50%), followed by cardiac changes. Surgical treatment was adopted in patients with progressive curves over 60 degrees, because of the inevitable deterioration in their general condition and the tendency of the deformity to become fixed. Pre-operative correction by Halo-traction results (52% correction) than Risser plasters (38%). Posterior arthrodesis by Harrington's method was carried out in all the more recent cases (forty four). Post-operative plaster was maintained for eight months and then replaced by an orthopaedic corset. At bony maturity there was an averaged improvement of 35% in the angle of curvature, and an average improvement of 6% in vital capacity. The best corrections were obtained in patients under fourteen (42%), in dorso-lumbar scoliosis (40%) and in patients with curves above 100 degrees (38%). There was an average increase in height of 9.1 cms and a reduction in the gibbus of 3.4 cms. The complications included one traumatic pneumothorax, eight pseudarthroses, and breakage of the distraction rod in two cases resulting in complete relapse of the deformity. In six cases the upper hooks became loos and there were two cases of postoperative staphylococcal infection. In the distally sited curves our present policy is towards combining posterior arthrodesis with Dwyer's anterior interbody fusion.
