Introduction: A New Era in ENT Care

Otolaryngology–head and neck surgery (ENT) encompasses the diagnosis and treatment of conditions affecting the ear, nose, throat, larynx, head, and neck. Artificial intelligence (AI) is emerging as a transformative force in this field, enhancing diagnostic accuracy, surgical planning, patient monitoring, and prognostic modeling through advanced analysis of imaging, voice, video, genetic, and neurophysiological data.¹ Despite growing research interest and compelling proof-of-concept studies—particularly in otology, neurotology, and head and neck oncology—the translation of AI into routine clinical practice remains limited, a gap often referred to as the “AI chasm.”²

Currently, only a small number of AI tools are specifically developed and FDA-cleared for ENT applications, highlighting the pressing need for clinical validation and integration strategies.³ Nonetheless, AI-driven tools—including automated image interpretation, speech and sleep disorder analysis, natural language processing for documentation, and patient triage systems—are beginning to enhance clinical workflows and education in ENT.⁴ Bridging the translational divide will require multidisciplinary collaboration focused on clinical utility, diverse data sources, and user-centered design to fully realize AI’s potential in improving outcomes and operational efficiency in otolaryngology.⁵

Diagnostic Advancements

AI is rapidly advancing diagnostic capabilities in ENT by improving imaging interpretation, pathology workflows, and voice analysis. Computer vision algorithms applied to otoscopic and endoscopic imaging can accurately identify ear infections, nasal polyps, tumors, and vocal fold abnormalities. AI-assisted flexible laryngoscopy, for instance, improves the detection of early glottic cancers and vocal cord lesions.⁶

In radiology, deep learning models enable precise segmentation and volumetric assessment of head and neck tumors on CT and MRI, aiding both diagnosis and treatment planning. Similarly, digital pathology tools powered by AI support rapid and accurate biopsy interpretation in thyroid and salivary gland tumors.^7,8

Beyond imaging, AI-based acoustic analysis of speech offers a promising avenue for early detection of vocal cord paralysis, spasmodic dysphonia, and neurodegenerative voice changes, such as those seen in Parkinson’s disease.⁹ Although these technologies show considerable potential, most remain in developmental stages, underscoring the need for robust validation studies and regulatory clearance to facilitate clinical deployment.

Surgical Applications

AI is also redefining surgical care in otolaryngology through enhanced planning, intraoperative navigation, and postoperative monitoring. Preoperatively, AI-driven 3D reconstructions of the sinuses, skull base, and airway improve visualization and allow for personalized surgical strategies. Predictive modeling using patient-specific imaging and clinical data further refines planning.¹⁰

Intraoperatively, AI supports real-time navigation and margin assessment, especially in high-risk procedures such as skull base and transoral robotic surgeries (TORS). The integration of robotics with AI augments precision, shortens operative time, and may reduce complications. Postoperatively, machine learning models trained on EHR data help predict complications such as bleeding, infections, or airway compromise, enabling earlier interventions.^11,12

Despite these benefits, challenges remain—particularly in workflow integration, data privacy, and regulatory oversight. Overcoming these hurdles is essential to safely and effectively implement AI tools in surgical ENT practice.

Personalized Oncology and Prognostic Modeling

AI is revolutionizing head and neck oncology by enabling truly personalized cancer care. Advanced algorithms synthesize genomics, histopathology, and imaging data to produce highly individualized risk profiles. Deep learning applications to CT, MRI, and PET imaging have achieved notable success in staging oropharyngeal and nasopharyngeal cancers, improving risk stratification and treatment planning.¹³

Machine learning models also guide therapeutic decisions, such as tailoring radiotherapy based on HPV status or predicting responses to chemoradiation. Decision-support systems help identify candidates for immunotherapy by integrating molecular and clinical data. In addition, AI tools quantify tumor-infiltrating lymphocytes (TILs) and tumor mutational burden (TMB), key biomarkers in immuno-oncology.¹⁴

These technologies also forecast recurrence, survival, and treatment-related toxicity, empowering clinicians to deliver adaptive, evidence-based care.¹⁴ However, widespread adoption depends on overcoming challenges like data standardization, interpretability, and integration into clinical workflows. Even so, the convergence of AI with precision oncology marks a critical frontier for improving outcomes in head and neck cancer management.
