Transoral Surgical Excision Of A Parapharyngeal Space Tumour: Case Report And Literature Review.

Background: The parapharyngeal tumour is a rare case of head and neck tumour. Benign and malignant tumours can arise from any of the structures contained within the parapharyngeal space. Pleomorphic adenoma is the most typical salivary gland tumour that is found in this space and surgical resection is the main treatment for this tumour. Since the modern era of the medicine, different kinds of diagnostic imaging and surgical approaches have been introduced to evaluate this tumour.

Case presentation: We present a case report of a parapharyngeal space mass that was found to be pleomorphic adenoma of minor salivary gland, their clinical presentation, radiological imaging and literature review of the transoral surgical approaches for parapharyngeal tumour.

Discussion and conclusion: The transoral approach remains one of the classical and effective methods for the resection of the benign prestyloid parapharyngeal tumour. The surgeons need to have a good knowledge of diagnostic imaging and surgical techniques to determine which surgical procedure is the best for the patients in order to eradicate the diseases and minimize the complications ultimately.
