Surgical treatment of parotid tumor involving the deep lobe is:-
Correct Answer: Deep lobe parotidectomy with facial nerve preservation
Description: Management of salivary gland tumors1) Surgery (principle Rx) - Surgical excision alone or in combination with radiotherapy- For Parotid tumor: depending on the involvement* Superficial parotidectomy* Deep lobe parotidectomy* Total parotidectomy* Radical parotidectomy- Other salivary gland tumors - En block excision of tumor + gland 2) Neck dissection: performed in- Clinically palpable nodes- High grade malignancies3) Radio therapy - Indications* High Grade tumor* Large primary tumor* Perineural invasion* Invasion of Lymph node* Positive margins* Cervical lymph node metastasis 4) No role of chemotherapy- In salivary gland tumors due to* Incomplete & sho-lived response* No survival advantages Types of Parotidectomy1. Superficial or lateral or classical parotidectomy:* For benign and malignant tumors involving superficial lobe* Salivary tissue lateral to facial nerve is removed2. Deep lobe parotidectomy:* For benign and malignant tumor involving deep lobe* Salivary tissue deep to facial nerve is removed3. Total conservative parotidectomy* For benign and malignant tumor involving both superficial + deep lobe* All salivary tissue is removed* Facial nerve is preserved4. Radical parotidectomy* For tumors invading facial nerve* All salivary tissue is removed + excision of facial nerve5. Extended radical parotidectomy* Radical parotidectomy + removal of adjacent structures (mandible, temporal bone,muscles)
