[Cancer of the ethmoid sinus].

Ethmoid sinuses are located at the level of the anterior skull base. Seventy to 80% of the ethmoid sinus malignant tumors are adenocarcinomas. Wood dust exposure is a carcinogen agent to ethmoid adenocarcinoma. More than 90% of patients with ethmoid adenocarcinoma are woodworkers. Craniofacial computed tomography scan and magnetic resonance imaging are always performed before treatment. It is always a multidisciplinary treatment including surgical resection followed by external radiation therapy. Some authors recommend a neoadjuvant chemotherapy. A total ethmoidectomy including the cribriform plate through a transcranial subfrontal approach is the best surgical technique. Local recurrence is the most frequent cause of failure; 5-year survival of patients with ethmoid adenocarcinoma is around 50%. A regular follow-up including clinical and radiological examination is always required.

[Enophthalmos following radical operation of the maxillary sinus and ethmoidal sinus].

Enophthalmos is usually a consequence of orbital trauma resulting in a blowout fracture of the orbital floor. We report here the case of a 35-year-old male who had a radical operation of the maxillary sinus and the ethmoidal sinus, and 2 months after the operation, developed spontaneous enophthalmos and ocular pain. The left orbit was enophthalmic by 5mm according to Hertel enophthalmometry. Surgical correction was performed under general anesthesia. The left orbit was explored through a transcutaneous incision of the left lower lid which revealed marked periosteal adhesions and absence of the bony floor of the orbit. A rib cartilage graft was used to reconstruct the floor of the orbit, and the globe was brought forward by means of retrobulbar placement. Enophthalmos and ocular pain disappeared postoperatively.

Study of ethmoid sinus involvement in multibacillary leprosy.

The nasal mucosal involvement in lepromatous leprosy is well recognized. Currently interest has centred around the involvement of paranasal sinuses in leprosy. They act as a reservoir and constant source of reinfection to the nasal mucosa. In the present prospective study 25 untreated patients with multi-bacillary leprosy were included. Clinical examination, computed tomography (CT) scan of paranasal sinuses, ethmoid sinus endoscopy and biopsy were carried out in all patients, to investigate the involvement of the paranasal sinuses in leprosy. Ethmoid sinus involvement was noted in 20 patients on CT scan. Bilateral involvement was more common (65 per cent). Anterior ethmoids were more commonly affected (65 per cent). On ethmoid sinus endoscopy abnormal mucosa was noted in 17 patients (68 per cent). Ethmoid sinus biopsy was confirmative in 16 patients (64 per cent). Statistically significant correlation was found between CT findings, sinus endoscopy and sinus biopsy findings.

Endoscopic sinus surgery for ethmoid sinus meningioma.

Meningiomas in the ethmoid sinuses are a challenge to manage. A 50-year-old man suffered from a left olfactory groove meningioma. He underwent a bilateral craniotomy to remove the tumor mass in August, 1997. During the follow-up period, a tumor was found in the right posterior ethmoid sinus. Endoscopic sinus surgery was performed to remove the tumor mass in August, 1998. Pathologic examination of the mass revealed a meningioma. No intraoperative or postoperative complications occurred, except for an episode of seizure.

Paranasal sinus radiology, Part 2A: Ethmoidal sinuses.

The clinician must have a high level of suspicion in order to detect ethmoidal sinus disease. Survey plain film radiographic examination may provide information about gross changes in ethmoidal sinus transparency and the sinus walls. Conventional tomographic study will often aid evaluation of the ethmoidal sinus walls which may be obscured by overlying structures on plain films. Computerized tomography adds a new dimension to ethmoidal sinus study. By revealing not only bone changes but soft-tissue abnormality as well, more complete understanding of the disease process is gained. Computerized tomography is particularly useful in evaluating orbital structural change due to ethmoidal sinus abnormality

[Clinical aspects and treatment of purulent anaerobic non-Clostridium ethmoid sinusitis].

The ethmoidal sinus was punctured for pus samples in 120 patients with purulent ethmoiditis. The sinus of 47.5% of the patients contained non-clostridial anaerobic infection. The species of the microflora and its sensitivity to antibiotics were defined. An effective system of examination and treatment of purulent ethmoiditis caused by anaerobic infection is proposed. The essential elements of this system are: aeration of the paranasal sinuses, immunostimulation and immunomodulation. For non-responders and subjects with frequent recurrences surgical intervention is indicated.

Orbital presentation of ethmoid sinus adenocarcinoma.

Ethmoid sinus adenocarcinoma with orbital invasion is distinctly uncommon. This case presented with epiphora, whereas proptosis and decreased ocular motility were later signs. Treatment was delayed for 4 months, while misdiagnoses like dacryocystitis and thyroid eye disease were entertained. Even an incisional biopsy was not sufficient for a conclusive diagnosis and adenomatous differentiation was only present in a small proportion of tissue available after an excisional attempt. The aggressive behaviour including this patient's death of metastatic disease, underlines the importance of considering secondary invasion from a sino-nasal malignancy in uncharacteristic orbital disease.

Carcinoma of the ethmoid sinus.

Cancer of the ethmoid sinus is a rare tumor in the head and neck, accounting for less than 1 per cent of all such malignancies. This paper examines squamous cell carcinoma arising in the ethmoid sinus, the most common form of ethmoidal malignancy in a series reviewed at the University of Michigan. Sixteen cases diagnosed between 1964 and 1974 (inclusive) were included in this study. Peak incidence of the disease occurred in the seventh decade of life. All patients had a minimum follow-up of at least five years. The patients had relatively common nasal complaints that unfortunately represented an unusual and frequently fatal disease. The symptoms of ethmoid sinus cancer are reviewed, and the many modalities of treatment that can be used are discussed. The problems of staging ethmoid sinus cancer are elucidated, and difficulties with the suggested classification systems are discussed. Ultimately, only 29 per cent of the patients survived five years.

Relationship between pediatric sinusitis and middle turbinate pneumatization--ethmoidal sinus pyocele thought to be caused by middle turbinate pneumatization.

OBJECTIVE: To investigate whether the presence of pediatric middle turbinate pneumatization causes narrowing of the ostiomeatal complex (OMC) and is associated with the development of paranasal sinusitis. METHODS: CT scans of 190 nasal sides of 95 children (1-15 years old) were analyzed for the presence of middle turbinate pneumatization and mucosal thickness in the paranasal sinus. RESULTS: Middle turbinate pneumatization was detected in nine (4.6%) of the nasal cavities. Only one of these sides was in a patient younger than 10 years of age, while the other eight sides were in patients at least 13 years old. In six of those nine sides with pneumatization, paranasal sinusitis was also found. However, the images showed that in five sides the middle turbinate pneumatization itself did not obstruct the OMC. In addition, the mean +/- standard deviation (S.D.) of the total score for the paranasal sinus opacification on the side which had the middle turbinate pneumatization was 5.67 +/- 2.95. The corresponding value for the 76 sides without pneumatization was 5.29 +/- 2.53, and the difference between these mean total scores was not statistically significant. However, in one side, the OMC was obstructed or narrowed due to the middle turbinate pneumatization, and an ethmoidal sinus pyocele formed on this side. CONCLUSION: A causal relationship was not found between middle turbinate pneumatization and the mechanism of development of paranasal sinusitis in children. However, in the event that the OMU becomes obstructed at some time, frequent cycles of improvement and aggravation of pediatric paranasal sinusitis may occur and lead to the development of a serious condition.

The frequency of entry into an ethmoidal sinus when performing a dacryocystorhinostomy.

Ethmoidal sinuses intervening between the lacrimal sac and the nose can cause confusion when performing a dacryocystorhinostomy (DCR). This study aimed to assess the frequency of entry into ethmoidal sinuses when performing a DCR and to identify any helpful distinguishing features, at surgery, between the ethmoidal and nasal spaces. Ethmoidal sinuses were initially entered in 23 of 50 standard DCRs (46%) in which the ostium was performed via the standard lacrimal fissure. Nasal mucosa was found to be 2 to 3 times thicker than ethmoidal sinus mucosa and less friable. Being aware of the risk of entering an ethmoidal sinus and of the anatomical differences between ethmoidal and nasal tissue greatly aids location during surgery and allows edge-to-edge suturing of sac mucosa to nasal mucosa in all cases.

Giant cell tumor of the ethmoid sinuses: diagnostic dilemma.

Tumors originating in the ethmoid sinuses are rare. Carcinomas of the ethmoid sinus, for example, comprise only 2-3% of all head and neck malignancies. Of this small sample, the ethmoid sinuses as the primary site varies from 5-30%. This paper presents the 14th documented case of giant cell tumor originating in the ethmoid sinuses. The pathology became the diagnostic dilemma; the case was originally diagnosed as an angiofibroma, later a reparative granuloma, and finally accepted as a giant cell tumor. The rationale for diagnosis and therapy is discussed.
