Imaging diagnostics strategy in maxillary sinus neoplasms.

Malignant neoplasms of maxillary sinuses are a serious diagnostic and therapeutic challenge, so the objective of a clinician is the planning of a cost-effective strategy promptly leading to proper diagnosis and the onset of treatment. Thus the aim of the paper was the elaboration of diagnostic strategy in maxillary neoplasms. There were analyzed 163 case records of 78 patients with maxillofacial neoplasms. The number and sequence of the conventional radiograms as well as diagnostic imaging methods were registered. There was proposed an algorithm of application of imaging techniques in diagnostics of neoplasms of maxillary antra. It was found that conventional X-rays are still valuable in screening for sinus pathology and as indication of the necessity of performing other imaging examinations. Computed tomography and magnetic resonance are complementary in visualization of pathologic masses and bone tissue destruction.

[History of treatment and classification of maxillary sinus neoplasms].

History of treatment of maxillary malignant neoplasms goes back to the middle of 19th century, when Gensoul and Lizzard performed their first maxillectomy. However the development of maxillar surgery is connected with achivements of Moure, who as the first one characterized and applied innovative skin cut on the face. Author presents the history of other surgical procedures in therapy of maxillary tumors and describes methods which are apply nowaday. Attention is paid to the Polish contributions and accomplishments in diagnostics and treatment of tumors localized in this area. The classification of maxillary tumors from Sebileau dissertation till the newest TNM classification from 2001 is described.

[Prognostic analysis of 151 patients with maxillary sinus malignant neoplasms].

BACKGROUND & OBJECTIVE: Five-year survival rate of patients with maxillary malignant neoplasms is low, the prognostic factors of these neoplasms were unclear. This study was to investigate prognostic factors of maxillary sinus malignant neoplasms. METHODS: Records of 151 inpatients with malignant neoplasms of maxillary sinus initially treated at Cancer Center of Sun Yat-sen University from Sep. 1983 to Mar. 1999 were reviewed. Of 151 cases, 72 were squamous cell carcinoma (SCC), 44 were adenocarcinoma, 16 were sarcoma, and 19 were other histological types; according to 1997 UICC classification, 7 were stage II, 55 were stage III, and 89 were stage IV; 66 patients received combined therapy of surgery and radiotherapy, 14 received surgery alone, 25 received radiotherapy alone, 39 received other treatments, and 7 gave up treatment. All patients were followed up for more than 5 years. Influences of clinicopathologic factors on prognosis of patients with maxillary sinus malignant neoplasms were analyzed by Kaplan-Meier method, and Cox regression model with SPSS10.0 software. RESULTS: Five-year overall survival rate of patients of </=40 years old was 55.7%, that of patients of >40 years old was 33.3%(P=0.030); that of patients with SCC was 30.2%, of patients with adenocarcinoma was 57.5%, of patients with sarcoma was 24.3%, of patients with tumor of other histological types was 50.7% (P=0.011); that of patients with tumor of stage II, III, and IV were 85.7%, 45.8%, and 32.7%, respectively (P=0.029); that of patients with cervical metastases was 14.4%, of patients without cervical metastases was 44.1% (P=0.005); that of patients with distant metastases was 14.3%, of patients without distant metastases was 41.1% (P=0.011); that of patients without treatment was 14.3%, of patients treated with surgery alone was 42.9%, of patients treated with radiotherapy alone was 32.3%, of patients treated with combined therapy of surgery and radiotherapy was 50.8%, of patients treated with other treatments was 29.1% (P=0.004). Univariate survival analysis showed that the above 6 factors were prognostic factors of patients with maxillary sinus malignant neoplasms. Multivariate analysis showed that combination of surgery and radiotherapy (P=0.004, OR< 1), clinical stage (P=0.025, OR >1), SCC (P=0.016, OR >1), and sarcoma (P=0.003, OR >1) were independent prognostic factors of patients with maxillary sinus malignant neoplasms. CONCLUSION: For maxillary sinus malignant neoplasms, patients with SCC or sarcoma had poorer survival than patients with adenocarcinoma or other histological types of tumor; patients with sarcoma had poorer survival than patients with SCC. The higher the patient's clinical stage was, the worse his prognosis was. Combination of surgery and radiotherapy may be the best treatment for patients with maxillary sinus malignant neoplasms.

Non-Hodgkin's lymphoma of the paranasal sinuses. Report of two cases.

Lymphoma of the paranasal sinuses is relatively rare compared to the occurrence of carcinoma in the same region. The diagnosis is often missed at the early stages of the disease. Two cases of primary extranodal lymphoma of the maxillary sinus are reported. The diagnosis of these malignancies is emphasized.

Exposure-response relationships between woodworking, smoking or passive smoking, and squamous cell neoplasms of the maxillary sinus.

A case-control study of squamous cell neoplasms of the maxillary sinus was performed in Hokkaido during 1982-86, with 169 cases and 338 controls matched for sex, age, and residence. The data were analyzed by a stepwise forward-selection method based on a conditional logistic-regression model without interaction terms, log-likelihood ratio tests, and chi-square tests for trend. Statistically significant linear trends were observed for associations between the risk of squamous-cell maxillary-sinus neoplasms and the duration of woodworking among men, the daily or lifetime amount of smoking among men, and the number of smokers in the household as an index of domestic exposure to cigarette smoke among women.

Beware of malignant lymphoma masquerading as facial inflammatory processes.

Considerable difficulty exists in diagnosing some sarcomas, lymphomas, and carcinomas that develop in the head and neck. Frequently these malignancies appear clinically as masquerading inflammatory disease processes. Recognition of these rare lesions usually occurs only after the inflammatory-like symptoms have failed to respond to conventional management, necessitating a more extensive evaluation and even repeated biopsies. The use of special stains, immunohistochemical studies, electron microscopy, and immunofluorescence techniques may still produce an inconclusive histopathologic diagnosis. This case report documents a rare extranodal malignant lymphoma of the right maxillary sinus that mimicked an odontogenic infection with superimposed chronic rhinosinusitis in a 19-year-old sailor. The cause of his chief complaint and presenting symptoms challenged the astuteness of clinicians, surgeons, and histopathologists on two continents and the high seas. Clinicians should maintain a high index of suspicion for malignancy when inflammatory-like lesions fail to respond to the usual appropriate management. Indications for early biopsy of suspect lesions and aggressive follow-up are emphasized.

The unilateral opaque maxillary sinus on computed tomography.

Computed tomography (CT) is the imaging method of choice for conditions that affect the paranasal sinuses. We reviewed all paranasal CT scans in the ear nose and throat (ENT) and maxillofacial surgery departments in 1 year. Of these 372 scans, unilateral opacity of the maxillary sinus was seen in 20 cases. Neoplastic disease was diagnosed in six of these, four of which were malignant. We describe the cases of neoplastic disease, particularly features of the history, examination, and scans that should alert the clinician to the possibility of sinister pathology. We emphasise the importance of nasendoscopic examination in the accurate assessment of sinonasal disease.

Maxillary sinus inflammatory disease: ultrasound compared to computed tomography.

Fifty-six patients (age range, 15-79 yr, average, 37.0+/-18.5 yr), with a clinical and/or radiological diagnosis of acute maxillary sinusitis, were prospectively studied with ultrasound (US) and computed tomography (CT). The imaging finding which supported the diagnosis of acute sinusitis with US was the identification of the hyperechoic posterior antral wall through the hypoechoic inflammation. The findings were compared to CT (3 mm axial sections). The sensitivity of US for maxillary sinus disease was found to be 66.7% and the specificity was 94.9%, which were similar to the plain film ones (65.2 and 96.8%, respectively). The results of the present study suggest US as the method of first choice for acute sinusitis of the maxillary antra, particularly for children and pregnant women.

The use of micro-titanium mesh for maxillary sinus wall reconstruction.

Operations on the maxillary sinus can lead to extensive bony defects of the facial and laterodorsal walls of the sinus. If there is no autogenous bone material available, the problem is to find a suitable substitute for reconstruction. We examined the suitability of micro-titanium mesh for reconstruction of the walls of the maxillary sinus. In 13 adult patients large defects of the walls of the maxillary sinus were reconstructed using micro-titanium mesh. Indications for operation were tumours, large dental-type cysts, traumatic bone loss and chronic inflammation in sinuses which had been previously operated on. Clinical and radiological examinations were carried out immediately after surgery and after a 3 months interval. Control by sinuscopy was performed in all patients. Great importance was attached to the following aspects: 1. correctly shaped reconstruction of the maxillary sinus 2. prevention of soft tissue prolapse into the sinus 3. aeration of the maxillary sinus 4. preservation of the facial contour

A-mode ultrasound in the diagnosis of chronic polypous sinusitis.

A-mode ultrasound (A-US) is a simple, non-invasive and non-ionizing method for detecting fluid or even mucosal swelling in inflamed maxillary and frontal sinuses. A-US has been shown to be a quite reliable tool in the diagnosis of acute maxillary sinusitis. However, controversy still exists over the reliability of A-US in detecting fluid retention or mucosal swelling in patients suffering from chronic polypous rhinosinusitis or in transantrally operated maxillary sinuses. We have compared the results of maxillary sinus A-US with computed tomography (CT) images in a selected series of chronic polypous rhinosinusitis comprising 40 patients. Fluid retention was seen in 20 of 79 maxillary sinuses on CT scanning. Only 6 of these 20 retentions were detected with A-US. There were 11 false positive findings. In six of these cases a back-wall echo was received through polypoid masses in the sinus. Mucosal swelling was also difficult to diagnose. The results of A-US were not easily reproduced; only in 50% of cases were identical results obtained by two investigators. We do not recommend the use of A-US to diagnose fluid retention or mucosal swelling in a patient with chronic mucosal changes in the maxillary sinus or if surgery has been performed on the anterior wall of the maxillary sinus.

Chronic maxillary sinusitis associated with the mushroom Schizophyllum commune in a patient with AIDS.

Invasive infection with fungi of the Basidiomycota (rusts, smuts, toadstools, mushrooms, and puffballs) is extremely rare. We report such an infection in a patient with human immunodeficiency virus disease who presented with chronic maxillary sinusitis associated with the mushroom Schizophyllum commune. The organism was isolated from the surgical drainage material, and septate hyphae were seen invading the maxillary submucosa. The limited literature on this subject is reviewed.
