Aetiopathology of maxillary swelling--a 3-year prospective study

A wide variety of lesions and not necessarily a malignant tumour can cause maxillary swelling. Non-specificity of clinical and radiological features of these maxillary lesions makes their diagnosis difficult. Review of literature adds a little regarding the aetiopathological distribution of the various lesions causing maxillary swelling. We present our finding regarding the relative distribution of various conditions causing maxillary swelling. The awareness of the spectrum of pathology related to maxillary swelling is essential for correct diagnosis and treatment. Forty-eight patients who presented with a swelling of the maxilla to our hospital between May 1998 and April 2001 were prospectively studied regarding the clinical presentations, radiological features and histological findings. Maxillary swelling was found to be caused by malignant tumours in 54.2%, benign neoplasms in 22.9% and non-neoplastic lesions in 22.9%. Overall squamous cell carcinoma (22.9%) was the commonest lesion, tumour of vascular origin was the commonest benign neoplasm and odontogenic cyst was the commonest among the non-neoplastic lesions.
