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: From June 1982 to June 1992, 144 ethmoido-sphenoido-orbital tumors have been referred to the neurosurgical department of Ste Anne Hospital. One hundred five of them were malignant lesions, among which 83 were included into our therapeutic protocol (1) neo-adjuvant chemotherapy (CDDP + 5-FU), (2) combined surgical procedure (subfrontal and transfacial), (3) postoperative radiotherapy. Fifty nine percent of the patients had no response to chemotherapy; 19% had a partial response (reduction of the tumoral volume > 50% and < 100%), 22% had a complete response. One patient had an immediate and transient postoperative rhinorrhea responsible for meningitis (acinetobacter) that was cured after a 3-day treatment. Four patients had postoperative meningitis without any cerebrospinal fluid leakage; they were also cured. Five patients had a local suppuration that was treated by subcutaneous drainage (n = 1) or the removal of the cranial basis graft (n = 4). Oncologic results are presented for only adenocarcinomas (n = 63) because they represent the only population of this series large enough to assure significant statistical figures. The global actuarial survival rate was 53% at 3 years and 42.5% at 5 years. The 5-year actuarial survival rate was 80% for T1 tumors, 60% for T2, 40% for T3, and 25% for T4. Patients with an intracranial extension had a 3-year survival rate of 19%; none survived after 4-year follow-up. Neo-adjuvant chemotherapy seemed to influence the survival: 100% survival rate at 5 and 10 years for the complete responders. We discuss the opportunity of intraorbital exenteration, the indications, and the limits of combined surgery. We emphasize the importance of neo-adjuvant chemotherapy and of combined surgical procedures, even when the patients are complete responders to chemotherapy: complete responders who had only a transfacial approach have a 5-year actuarial survival rate of 80% (instead of 100% when a combined procedure was performed). Those who were not operated primarily recurred within 3 years and then had to be operated. We propose to follow such a combined surgery for all large ethmoidal cancers (T3 and T4) and for small tumors (T1 and T2) developed superiorly and posteriorly. Anterior T1 and T2 tumors should be operated through a single transfacial route.Surgical Neurology 08/1994; 42(2):98-104. DOI:10.1016/0090-3019(94)90367-0 · 1.67 Impact Factor

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.Acta Neurochirurgica 02/1995; 133(3-4):201-5. DOI:10.1007/BF01420075 · 1.77 Impact Factor
Article: Adenocarcinoma of the ethmoid sinus[Show abstract] [Hide abstract]
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.Head & Neck 07/1995; 17(4):303-11. DOI:10.1002/hed.2880170406 · 2.64 Impact Factor
