Transoral Approach to the Giant Deep Lobe Parotid Gland Pleomorphic Adenoma.

Parapharyngeal space tumors are rare tumors that make up about 0.5% to 1% of all head and neck neoplasms. The majority of parapharyngeal space tumors, which are usually benign, consist of salivary gland tumors and neurogenic tumors. Although the transcervical, transparotid or transmandibular approach is generally preferred for the excision of these tumors, the transoral approach, which is more advantageous in terms of cosmetics and function, can be applied in selected cases. This article presents a case in which the giant pleomorphic adenoma originating from the deep lobe of the parotid gland is removed by transoral approach.
