ENT Credentials 101: What “FACS” and “FAAO-HNS” Actually Mean
The ears, nose, and throat play vital roles in daily comfort, communication, and overall well-being. In medicine, including ENT, a physician’s credentials are a critical key in helping patients choose qualified healthcare providers and practices. They indicate that a physician has undergone rigorous specialty training and education in their field of specialty.
This guide was created by SoCal Breathe Free to help patients in Burbank, CA, understand the basics of ENT credentials, especially the terms “FACS” and “FAAO-HNS”, which are mostly seen with the titles of many ENT specialists.

What Is FACS?
In medicine, “FACS” stands for “Fellow of the American College of Surgeons”. It is a professional fellowship designation for surgeons who have passed a set of education, qualification, and ethics requirements to join the American College of Surgeons (ACS). The ACS is a professional medical association for surgeons and surgical team members.
An FACS fellowship indicates that a surgeon:
- Has been peer-reviewed and accepted into the ACS
- Has completed an accredited surgical program
- Has met the requirements of board certification in their field of surgical specialty (e.g., the Otolaryngology – Head and Neck Surgery), which is a requirement for FACS eligibility
- Showcases an ongoing commitment to surgical education, training, ethical practice, and high standards of medical care
While FACS is a respected professional designation, it is not the same as board certification.
What Is FAAO-HNS?
In ENT medicine, “FAAO-HNS” stands for “Fellow of the American Academy of Otolaryngology – Head and Neck Surgery”. It is a professional fellowship designation for ENT specialists who have met the requirements for education, training, and ethics to join the American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS). The AAO-HNS is the main professional organization for ENT specialists in the United States.
An FAAO-HNS fellowship indicates that an ENT specialist:
- Is in good standing with the AAO-HNS
- Is committed to professional engagement and involvement in ENT-specific research, training, best practices, and standards of care
- Showcases an ongoing commitment to ENT education, training, guidelines, and ethics of patient care
- Has completed training in otolaryngology – head and neck surgery and met the academy’s membership requirements (which are separate from board certification)
FACS vs FAAO-HNS: What Is the Difference?
Both FACS and FAAO-HNS are optional and voluntary professional society memberships. Neither is a board certification.
Here’s a quick summary of the differences between FACS and FAAO-HNS:
| FACS (American College of Surgeons) | FAAO-HNS (ENT-Specific Academy) | |
| American College of Surgeons (ACS) | Governing organization | American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS) |
| All surgical specialties | Specialty | ENT |
| Surgical competence and ethics | Focus | Professional engagement and involvement in ENT medicine |
| Required for eligibility by the ACS | Board certification | Not required, but common among members |
| MD, FACS | Credential line | MD, FAAO-HNS |
To put it simply:
- An FACS fellowship signifies that an ENT surgeon has the surgical competence and commitment to upholding professional and ethical standards as set by the ACS.
- An FAAO-HNS designation indicates the ENT specialist is actively engaged in ENT-specific research, training, and best practices.
- Board certification is required for FACS and commonly held by FAAO-HNS members, but neither is itself a board certification.
The Highly Recognized ENT Credential: Board Certification in Otolaryngology – Head and Neck Surgery
Many ENT healthcare providers have both the FACS and FAAO-HNS credentials. However, a board certification in Otolaryngology – Head and Neck Surgery remains a highly recognized credential in ENT care.
Being a board-certified ENT specialist means that a healthcare provider has undergone specialty training in ENT medicine and has met industry-wide professional standards as set by the American Board of Otolaryngology – Head and Neck Surgery (ABOHNS), the official certifying body for otolaryngologists practicing in the United States. ABOHNS is officially recognized by the American Board of Medical Specialties (ABMS).

What is an ENT?
An ENT doctor, formally known as an otolaryngologist or simply an ENT, is a healthcare provider who specializes in treating and diagnosing conditions affecting the ears, nose, and throat. Some ENT doctors take their specialty further by training in other subspecialties, including the more complex issues of the head, mouth, neck, and facial structures.
ENTs are trained to evaluate and manage a wide range of concerns, including allergies, sinusitis, hearing loss, tinnitus, and sleep-related breathing disorders, and may offer non-surgical and surgical treatment depending on the condition.
What does an ENT treat?
An ENT is equipped to treat a wide variety of ENT conditions and concerns, including:
- Recurring ear infections
- Hearing loss
- Tinnitus
- Chronic nasal congestion
- Chronic cough

Is ENT and otolaryngologist the same?
Yes, ENT and otolaryngologist refer to the same specialist.
ENT is the more common layman’s term because it’s easier to remember, while otolaryngologist is the official medical term. It recognizes that they treat more than ear, nose, and throat conditions, and the term is more consistent with the name of the governing board and certification.
What is the difference between a licensed and board-certified physician?
In the United States, physicians must obtain a medical license in the state where they work to legally practice, and this includes ENT care. A medical license is mandatory, while certification is a voluntary program that licensed physicians may choose to pursue.
Are all otolaryngologists licensed and board-certified?
All otolaryngologists must be state-licensed to legally practice. However, board certification is optional and not held by every ENT provider.
