Malignant tumours of the maxillary sinus usually presents at an advanced stage due to the surrounding bony walls of maxilla. So by the time the patients reaches an oto-rhino-laryngologist, the condition is advanced making treatment difficult. The malignant tumours of maxillary sinus occurs in only one in 2,00,000 persons per year. This emphasizes the importance of clinical features, in detecting the disease at an earlier stage and to improve the prognosis of the patients. Hence this study was conducted to evaluate the importance of symptoms and signs in facilitating early diagnosis and in predicting the appropriate extent of disease. The aim of the study is to study the age and sex incidence of the tumours, to find the incidence of different symptoms, to correlate the clinical findings and stage of the disease, to compare the clinical staging and radiological staging with preoperative involvement and to determine the prognostic factors in malignant tumours of maxilla particularly in relation with staging of the lesion. Malignant tumours of maxillary sinus present in a quite advanced stage, even though the duration symptoms may be less. The tumour is usually more extensive than the symptomatology and clinical examination suggests. The low success rate may be due to advanced tumour at the time of diagnosis. Symptoms and signs have important role in detecting malignant tumours of maxillary sinus earlier and in improving the outcome of the treatment. Nasal symptoms are the commonest symptom and majority of the patients presenting with nasal symptoms belong to T3 and above even at initial presentation. Clinical staging tends to understage and radiological staging tends to over stage the tumour. Complete surgical removal of tumour with postoperative radiation therapy remains the gold standard for resectable lesions. Maintaining a high suspicion while treating patients with prolonged unexplained nasal problems could help in improving the success rate in malignant tumours of maxillary sinus.
