The area for medical consultation and examination is located on the third floor of Policlínica Gipuzkoa in San Sebastián.


The centre has a hospitalisation area with 142 beds in single and double rooms and suites, with excellent care from our highly qualified nursing team.


The radiology service collaborates in the diagnosis with ultrasound techniques, computerised axial tomography (CAT) and with a new high-precision 3T nuclear magnetic resonance (NMR) device for salivary gland pathology.


The surgical block is an extension of the main building with 12 state-of-the-art operating theatres, 15 post-anaesthesia resuscitation units and 14 intensive surveillance boxes.

Most of the surgeries performed by the SIALOSS team are carried out in the Day Hospital, within the surgical block, where patients spend a few hours in one of the 18 individual rooms before being discharged.
