  • Development of a patient-centered quality of life outcome measure after parotidectomy, Phase II Rochester, Minn.

    The purpose of this study is to explore the quality of life value of various surgical and functional outcomes after parotidectomy from a patient-centered perspective. Also, to develop a comprehensive patient-centered outcome measure after parotidectomy using a patient survey. Addittionally, to validate the content of the patient survey.

  • Oropharyngeal Human Papillomavirus Prevalence in Partners of Patients with Oropharyngeal Squamous Cell Carcinoma Rochester, Minn., Scottsdale/Phoenix, Ariz.

    We are doing this research study to find out if partners of subjects with oropharyngeal cancer are infected with human papillomavirus (HPV) in their mouth or throat. Human papillomavirus causes some types of oropharyngeal cancer. It is not known if sexual partners of patients are at higher risk of having oral or throat HPV infection. It is also unknown if certain sexual behaviors increase the risk of oral HPV infection

  • Post-parotidectomy Facial Paresis: Intraoperative and Postoperative Factors Scottsdale/Phoenix, Ariz., Rochester, Minn.

    This is a prospective trial of facial nerve monitoring in patients undergoing parotidectomy to see if the facial nerve monitor provides useful information to operating surgeons and if the information provided can predict degrees of postoperative facial nerve paresis. Additionally, the study will determine if performing daily facial rehabilitation exercises provides a benefit in reducing time to recovery of temporary post-parotidectomy paresis.

  • Use of Automatic Periodic Stimulation and Continuous EMG for Facial Nerve Monitoring During Parotidectomy Rochester, Minn.

    The purpose of this study is to document the safety of the Medtronic automatic periodic stimulating (APS) Electrode Stimulator during a parotidectomy and potentially prevent post-operative facial nerve weakness, which is a relatively common outcome after parotid surgery.
