A parotidectomy is the surgical excision (removal) of the parotid gland, the major and largest of the salivary glands. The procedure is most typically performed due to neoplasms [ 1 ] (tumors), which are growths of rapidly and abnormally dividing cells.
After the time of enucleations, pleomorphic adenomas of parotid gland were recommended to be routinely treated with superficial or total parotidectomy. [13] These procedures combine complete tumor removal and identification of the main trunk of facial nerve during surgery to avoid any lesions to the nerve.
The parotid duct, a long excretory duct, emerges from the front of each gland, superficial to the masseter muscle. The duct pierces the buccinator muscle, then opens into the mouth on the inner surface of the cheek, usually opposite the maxillary second molar. The parotid papilla is a small elevation of tissue that marks the opening of the ...
They are a relatively common complication following surgery to the salivary glands, [4] commonly parotidectomy (removal of the parotid gland). [5] In this case the sialocele is the result of saliva draining out of remaining parotid tissue, and occurs about 5 to 10% of cases of superficial (partial) parotidectomy. [5] [6]
The auriculotemporal nerve is a sensory branch of the mandibular nerve (CN V 3) that runs with the superficial temporal artery and vein, and provides sensory innervation to parts of the external ear, scalp, and temporomandibular joint. The nerve also conveys post-ganglionic parasympathetic fibres from the otic ganglion to the parotid gland. [1]
Treatment of individual infections may prevent injury to the gland parenchyma. In the past, the disease was treated with aggressive surgical interventions such as Stensen’s duct ligation, superficial or total parotidectomy, and tympanic neurectomy. Nowadays, the disease is managed with sialendoscopic procedure.
The neck dissection is a surgical procedure for control of neck lymph node metastasis from squamous cell carcinoma (SCC) of the head and neck. [1] The aim of the procedure is to remove lymph nodes from one side of the neck into which cancer cells may have migrated.
Following this, the surgeon can use the endoscopic method. The first step in this is anesthetizing and laving the duct with 2 percent lidocaine and saline. If there is no improvement, the surgeon then can insert a dilation balloon, which can be inflated up to 3 mm. The pressure created by the inflation can be sufficient to dilate most strictures.
