The Invention provides a three"dimensional model (1) of at least & portion of a human head or a skull for training pituitary gland surgery by transnasal access. The model (1) includes a nasal cavity portion (2) imitating the nasal cavity region, of the head/skull and a pituitary gland portion (3) imitating the. pituitary gland region of the head/skull. The pituitary gland portion (3) can be accessed from the outside of the model (1) by surgical instruments extending along the nasal cavity portion (2) from the outside of the model (1) to the pituitary gland portion (3). The pituitary gland portion (3) of the model (1) comprises a first portion (3a) having a first texture imitating unhealthy/ abnormal pituitary gland tissue to be resected, and a second portion (3b) having a second texture imitating healthy/normaI optic nerve, brain and pituitary gland tissue not to be resected. |
