I use an SA (surgical assistants is what we call them) or my PA. When I first went into practice, it was just SAs. Going into practice is an adjustment because you have to figure out how to get the view you need with the help you have. Experienced assistants will usually know and are good, but they also have to figure you and your style out too. You also have to learn the local instrumentation or ask them to order certain things for you, as it can vary slightly by region and hospital and the SAs can tell you what others use. You already are aware that your attendings are doing excellent retraction for you, so you are already self aware. If you scrub in with just a med student or junior resident, can you get them to expose things properly for you? It's good practice for the future.
Echo this. I have an NP and I'm considering changing jobs and am bringing her with me if I move as a condition of employment because I have zero desire to repeat this process. Anyone can be taught to do anything in surgery and you do not need a medical degree to reproduce reliable technical skills *ON A TEAM*. What is more important is consistency and the same people/team. Some places can provide that and some can't. For some specialties (general surgery) its a luxury, and others (CV, surg-onc, ENT oncology, microvascular plastics) its a requirement depending on the complexity of what you're doing.
Anywhere you go you'll have to train said person and it will take time but most seasoned (even just ~3 years or more) RNFAs don't need to be taught tissue handling, they just need to be taught the routines.
Find out what you realistically need and put some hard thought into it. If you're good at your skill and your surgery is not overly complex be honest with yourself - you could probably do a thyroid or a para with anyone. If you're doing repeat thyroids with tracheal invasion then... well, yea. You need someone who knows what is going on. If that happens once every other month you probably want another surgeon assisting you. If that happens every single day then you need an NP or PA. If it happens once every 10-20 cases but you think you can handle it an RNFA who knows what to do during 'normal' cases would probably be totally fine.
Personally, I *need* someone who has workable knowledge of retroperitoneal and hepatic anatomy, knows how the iron intern works for retracting and can place it independently, is confident and has steady hands in the face of massive bleeding with retraction and knows without being told what instrument needs to be in my hand, and can close fascia/skin. I am very slowly and very carefully working on low risk anastomoses mostly so that if/when we have residents she can guide them with me scrubbed out to give them autonomy on the GJ of a whipple which is a good anastomosis for a resident to do with low supervision and me physically not present. There are programatic goals I have to comply with and achieve as well as personal time management of a soul crushingly big service and I needed that. Part of that is also that the list of people I can call for help are 1) out of my discipline and 2) far away at any given moment and I need someone who can help me safely temporize a problem intra-operatively until my help arrives. Most people honestly do not need that. It is also a huge expense. My NP generates zero non-surgical RVUs and assistant RVUs, while not negligible, probably don't cover her salary. RNFAs way cheaper.
If you're doing primarily thyroid/para/neck dissections and not more complicated stuff a dedicated scrub tech would absolutely be fine and you do not necessarily even need an RNFA. But dedicated and consistent is key. If you *can't* get a dedicated scrub tech, I would start with an RNFA to see how that suits your needs. After a month on ENT oncology, I would never be an ENT oncologist unless you had an NP or PA *and* a partner available for when the **** turns into the stinky ****.
