      Clinically, Dr. Ryan is skilled in the care and management of patients with benign and malignant tumors of the head and neck and obstructive salivary disease with the appropriate application of robotic, endoscopic, minimally invasive, and traditional surgical techniques. He helps direct the Robotic Head and Neck Surgery program (for TORS: TransOral Robotic Surgery), the Thyroid and Parathyroid Surgery Center, and the Salivary Gland Surgery Center at UCSF. He has specific interests and expertise in thyroid and parathyroid surgery, sialendoscopy/salivary duct surgery, salivary tumor surgery, upper aerodigestive tract surgery (of the oral cavity, oropharynx, hypopharynx, larynx, upper esophagus, and trachea), skin cancer surgery, and regional facial, head and neck reconstruction. He regularly performs ultrasonography in clinic and in the operating room for his patients. He is a member of the Head and Neck Tumor Board, Thyroid Tumor Board, and Visible Tumor Board at UCSF.

      Dr. Ryan is committed to providing adequate information and being as accessible as possible for his patients.

      Over each of the last 2 years, the division of Head and Neck Oncologic/Endocrine Surgery consisting of Drs. Lisa A. Orloff, Steven J. Wang, P. Daniel Knott, and William R. Ryan and the nursing and administrative staff, together won the Pinnacle award, which is given to the medical or surgical specialty group at the UCSF medical center with the highest patient satisfaction scores.

      Academically, Dr. Ryan is actively involved in teaching and lecturing in the Otolaryngology-Head and Neck Surgery Residency-Training Program, the UCSF School of Medicine, and at academic conferences. His research interests include investigations of the salivary function in the setting of oncologic treatments and obstructive ductal disease, the impact of sialendoscopy and salivary duct surgery, head and neck surgery technique variance and commonalities, the use of integrative health care in head and neck oncology, and the benefits and drawbacks of cancer surveillance imaging. He is a committee member in the American Head and Neck Society and the American Academy of Otolaryngology-Head and Neck Surgery. He is a reviewer for the journals: Head and Neck and JAMA-Otolaryngology-Head and Neck Surgery. He also helps direct the annual UCSF/Tripler Otolaryngology-Head and Neck Surgery Update Course in Honolulu, HI.
