Training in functional endoscopic sinus surgery (FESS) is an essential part of each ENT resident and it takes place on a very fragile area. This study focus on showing the learning curve of FESS, using an anatomical model such as the sheep's head. Four residents in our centre performed dissections. Each of these residents operated eight sheep's head. They performed an endoscopic septoplasty followed by maxillary antrostomy, total ethmoidectomy and frontal sinusotomy on every head. A staff member guided all procedures and checked for the appropriate dissection and complications occurred. Analysis was made upon the residents’ performance of their first four septoplasties and eight nasal sides against their subsequent performance of the same. Final procedures presented better outcomes than the initial ones on every step of them. Results were measured by means of decrease of time ( P
