A rare 'parotid tumour'.

Area of Science:

• Oral and Maxillofacial Surgery
• Head and Neck Surgery
• Dermoid Cyst Research

Background:

• Ganglions, typically found in joints, can rarely present as tumors in the parotid gland.
• Distinguishing parotid tumors from other cystic lesions is crucial for appropriate management.
• The deep lobe of the parotid gland poses unique surgical challenges due to its proximity to vital structures.

Observation:

• A case of a temporo-mandibular joint ganglion presenting as a deep parotid lobe tumor is described.
• The lesion was initially suspected to be a parotid gland tumor.
• The ganglion mimicked a neoplastic process within the parotid gland.

Findings:

• The ganglion was successfully managed via simple excision after mobilizing the superficial parotid lobe.
• Preserving the superficial lobe of the parotid gland resulted in a superior cosmetic outcome, avoiding pre-tragal depression.
• This conservative surgical approach is effective for deep parotid lobe cystic lesions.

Implications:

• This case highlights the importance of considering extraglandular cystic lesions in parotid tumor differential diagnoses.
• Conservative management of parotid cystic lesions can achieve excellent functional and aesthetic results.
• Further research into the presentation and management of rare cystic lesions in the head and neck region is warranted.
