Rhinosinusitis affects up to 15% of the adult population. Surgery is warranted if non-surgical options do not give satisfactory results. First-step surgical options include balloon sinuplasty or functional endoscopic sinus surgery (FESS). A basic FESS includes removal of the uncinate process and opening of the maxillary ostium. 


The Eustachian tube (ET) equalizes pressure between the middle ear and the nasopharynx. Eustachian tube dysfunction (ETD) may lead to otitis and hearing loss. ET balloon dilatation Eustachian aims to widen the medial cartilaginous part of the ET, hence improving its function.

Surgical task trainers enjoy wide use in medical training. Time spent using trainers leads to improved confidence and higher success rates.

Tommy Ess is designed for training the basic manual skills needed in basic FESS and balloon dilatation (maxillary, frontal, Eustachian tube). It is suitable for learning endoscopic surgical instruments and techniques. In addition, the trainees learn the importance of the ergonomic working conditions and the stability of the arms.

key features

  • Designed by ENT surgeon and clinical teacher with more than 20 years of experience
  • Enables unlimited repetitions: uncinatus and the maxillary wall are made from cardboard and can be replaced in seconds
  • Uncinectomy, opening of the maxillary ostium, inferior antrostomy
  • Maxillary sinus, frontal sinus, Eustachian tube

Maxillary wall and the uncinatus are formed by cardboard strips. Templates for the strips can be found from the side of the Tommy. You can change the ”feel” of the operations by using different types of cardboard (a toilet paper roll works fine, although a bit too hard). Fix the cardboards with tape.


Suitable for both right- ….

…and left-handed surgeons.


Eustachian tube dilatation feels even more natural if you put a small amount of ultrasound gel (or something similar) to this small orifice

Endoscopic sinus surgery (ESS) training with ”Tommy Ess”. Back-biter uncinectomy and identification of the ostium.

Widening of the maxillary ostium. Uncinatus and the maxillary wall are made from cardboard and can be replaced in seconds.

Illumination can be used to confirm correct entry into the frontal recess and provides transcutaneous confirmation prior to frontal sinus procedures such as balloon dilatation. Demonstrated nicely by ”Tommy Ess” (and Stryker XprESS).
