Andrea Achena, MD, is an Italian otolaryngologist with expertise in otology, rhinology, anterior and lateral skull-base surgery. After graduating summa cum laude from the University of Cagliari, he completed his ENT residency at the Universities of Milan (2019–2022), earning a final grade of 70/70 cum laude, with an experimental thesis on sinonasal intestinal-type adenocarcinoma. During residency he went on to a dedicated otology fellowship at Instituto de Otología García-Ibáñez, Bercelona.

Since 2022 he has served as Consultant ENT at ASST Grande Ospedale Metropolitano Niguarda in Milan. In this period has logged more than 2500 ENT operations, over half as primary surgeon, managing complex otologic, rhinologic, anterior and lateral skull-base cases with advanced endoscopic and micro-surgical approaches. He has further honed his surgical expertise through advanced dissection courses in otology (Piacenza, Barcelona), rhinology and anterior skull base surgery (University of Milan; Hospital Niguarda), and temporal bone dissection (Padua) and in 2025 earned an advanced master’s in Otoneurology from the University of Padua.

Dr Achena is an active member of SIOeChCF, the leading Italian society of Otolaryngology, and of its young-professionals section, GOS, where he serves on the executive board. As contributor to the research field, he has authored twelve peer-reviewed papers regarding different ENT topics. His work blends minimally invasive surgery with translational research to improve outcomes for patients with complex ear and sinus disease.
