  Purpose

The most common benign tumor of the parotid gland is the so called pleomorphic adenoma. Although benign, this tumor may recur after surgical removal due to tumor cells left behind during the surgical operation. Thus, pleomorphic adenomas have been treated with wide resection similar to malignant tumors. This extensive surgery often leads to injury to the motor nerves responsible for facial expression and eye protection. The investigators propose less extensive surgery which should be thorough enough to prevent tumor recurrence while keeping the facial nerve out of risk.

Primary Outcome Measures:
  • Incidence of facial nerve palsy [ Time Frame: at six months after surgery ] [ Designated as safety issue: No ]
    using clinical neurological examination


Secondary Outcome Measures:
  • Temporary facial nerve palsy [ Time Frame: at three months after surgery. ] [ Designated as safety issue: No ]
    using clinical neurological examination

  • Cosmetic results [ Time Frame: at three weeks after surgery ] [ Designated as safety issue: No ]
    The patient subjective cosmetic scoring and an objective observer cosmetic score will be recorded for each patient to evaluate the appearance of the parotid area after surgery

  • Operative timing [ Time Frame: at the date of surgery ] [ Designated as safety issue: No ]
    Median and range of operative time per intervention arm willl be recorded

  • Temporary facial nerve palsy [ Time Frame: at day one after surgery ] [ Designated as safety issue: No ]
    using clinical neurological examination


Estimated Enrollment: 116
Study Start Date: September 2012
Estimated Study Completion Date: February 2016
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Quadrant parotidectomy
Patients in this arm will receive excision of the parotid gland quadrant harboring the tumor
Procedure: Quadrant parotidectomy
Excision of one quadrant of the parotid gland which is comparable to half of the superficial lobe of the gland
Active Comparator: Superficial parotidectomy
Patients in this group will receive superficial parotidectomy
Procedure: Superficial parotidectomy
Excision of the whole superficial lobe of the parotid gland

Detailed Description:

Pleomorphic adenoma is notorious of its propensity to local recurrence due to the microscopic extracapsular extension of the tumor. Superficial parotidectomy (SP) is the standard treatment. Extracapsular dissection (ED) has been proposed to minimize the risk of facial nerve palsy. However, the oncologic safety of ED is controversial in the literature. We propose quadrant parotidectomy (QP) which is less radical than SP and less conservative than ED. QP entails dissection overlying one primary division of the facial nerve leaving the other division undisturbed while the resection safety margin is still generous.

Surgery for pleomorphic adenoma is a compromise between radicality and facial nerve morbidity. Risk of local recurrence is imprecisely described in the literature and is universally regarded as infrequent and remote. Many studies did not report recurrent cases. Thus, Facial nerve injury is the main concern of parotid surgeons and is considered the primary end point of this study.
