ABSTRACT New therapeutic modalities for Ethmoidal Adenocarcinomas are presented. Thirty three patients harbouring such a tumour have been treated during the last four years. Twenty three were included in the following protocol:--the first step consisted in inductive chemotherapy based on a four-day course of continuous cisplatine (CDDP) and 5-fluoro-uracyl (5-FU infusion)--the second step was the tumour removal, which was performed through a combined transfacial and subfrontal approach. A contralateral ethmoidectomy was always performed. The integrity of the sphenoidal sinus was systematically checked. The cranial base was reconstructed with madreporic coral grafts; then a large extra-dural pediculated galea flap was placed onto the anterior base to line the sub-frontal dura. The authors discuss the results of this series of rare tumours.

    ABSTRACT: The authors, since 1985, have used 587 Madreporic Coral grafts as bone substitute in a total of 183 patients, among them in 80 cases for repair of cranial base bone defects. They report their long-term results. Partial resorption to about 40% of the initial volume occurred in almost all cases within 8 to 10 months, with complete resorption after about one year. 20% of the coral blocks moved spontaneously or split into pieces, but could easily be withdrawn rhinoscopically through the nostrils. No CSF leakage was noticed afterwards. The local infection rate was only 4%, always close to the basal coral graft. This is lower than the infection rate after using autologous bone harvested from the inner table of the bone flap (20%). Infections were cured by removal of the coral graft. Despite the mentioned draw backs, Madreporic Coral graft implants can be recommended as bone substitute in cranial base surgery: 1. The material simplifies the surgical procedure; 2. Harvesting of autologous bone is no longer necessary; 3. Transmission of infections like AIDS, Hepatitis C or Creutzfeld-Jacob-disease can be avoided with certainty.

    ABSTRACT: Objective: To determine risk factors and evaluate the treatment of ethmoid adenocarcinoma. Epidemiologic data were recorded and compared with the literature.Materials and Methods: A multicenter and retrospective study. The medical records of 418 patients who had presented with ethmoid adenocarcinoma at 11 French hospitals from 1976 to 2001 were analyzed to determine the clinical characteristics and treatment of the disease.Results: The gender ratio was 2.8 men per 1 woman. Toxic exposure was classic for this lesion, exposure to wood and leather for most cases. The mean age was 63 years (range 31–91). Symptoms were nonspecific and based on clinical rhinologic signs. Nasal endoscopy after mucosal retraction was found useful to evaluate the extension of the lesion and to perform biopsies. Computed tomography scan and magnetic resonance imagery must be carried out prior to treatment to define extra nasal extension. The survival rate was significantly influenced by the size of the lesion (T4, N+) and extension to brain or dura. Surgery with postoperative radiotherapy remains the treatment of choice. Total excision must be a major priority, as confirmed in our series.Conclusion: This retrospective study was, to our knowledge, the largest ever reported in the literature. This series confirmed the risk factor of this lesion as well as the lesion's influence on the survival rate. Surgery is the most important part of the treatment. Local recurrences were responsible for the poor prognosis of this lesion.

    ABSTRACT: Carcinoma of the paranasal sinuses is rare. The majority of these originate in the maxillary sinus with primary ethmoid carcinomas occurring in up to 20% of cases. Adenocarcinomas comprise up to 50% of the ethmoid malignancy. The relative rarity of tumors originating in this area has led to their inclusion in series that consist mainly of maxillary antral tumors. A retrospective chart review of all patients presenting with primary ethmoid adenocarcinoma at West Virginia University Hospitals between 1988 and 1993 was undertaken. Only patients whose epicenter was believed to be in the ethmoids were included in this analysis. CT scans, MRIs, operative notes, pathology, and final outcome were all analyzed. Eight patients with primary ethmoid adenocarcinoma were treated during this time span. The male to female ratio was 1:1 with a mean age of 50 years. Symptoms had been present from 3 to 18 months (mean 8 months). All patients underwent craniofacial resection with 5 patients receiving postoperative radiotherapy. Pathologically 4 patients had cribriform plate erosion, 2 had dural involvement, and 1 had extension into the sphenoid sinus. With a mean follow-up of 45 months (9-71 months) 7 patients are disease free and 1 patient has died of disease. Obtaining clear margins by craniofacial resection is essential to the management of adenocarcinoma of the ethmoid sinuses. Radiotherapy is reserved for positive margins, cribriform plate penetration, dural invasion, and high-grade lesions that are close to the cribriform plate. Local control was obtained in 87% of our patients.
