Carlos O'Connor Reina is an ENT physician with a career focused on the diagnosis and treatment of sleep disordered breathing. His passion for innovation led him to develop Airway Gym, the first medical application dedicated to upper airway myofunctional training, with the aim of offering an effective, accessible and evidence-based therapeutic alternative for patients with obstructive sleep apnoea.

He has introduced for the first time in Spain new procedures that treat snoring, sleep apnoea and sinusitis. Of particular note are the new diagnostic procedures using induced sleep endoscopy together with new pharyngoplasty techniques. He is a specialist in respiratory sleep disorders (snoring and apnoea) and is the first Spanish ENT specialist to be recognised as an EXPERT SOMNOLOGIST by the European Sleep Research Society.

His work marks a before and after in the integration of myofunctional therapy into modern clinical practice by combining technology, science and a patient-centred approach. He has actively contributed to breaking down barriers in sleep medicine, positioning functional treatment as a first-line tool.
