Assessment and Management of Difficult Airway Post Mandibulectomy: A Narrative Review

Mandibulectomy most commonly performed as surgical management of oropharyngeal carcinoma leads to a wide array of anatomical and physiological changes which result in an anticipated difficult airway. There may be posterosuperior displacement of hyoid bone and tongue leading to reduction of retropalatal space along with loss of structural support to the tongue predisposing it to prolapse and development of obstructive sleep apnoea. Bulky flap reconstruction, limited mouth opening, and radiotherapy limiting neck mobility further compound the difficulty in airway management. This leads to a wide spectrum of issues ranging from difficulty in face mask ventilation to laryngoscopy and intubation. It is essential to individualize each case with a preformulated strategy outlining the primary and alternative approaches. A literature search was carried out using search engines like PubMed, Embase, Medline, and Google scholar using the terms “Difficult airway”, “Post-mandibulectomy”, “Difficult laryngoscopy, and Intubation”. The available literature was thoroughly reviewed by the authors before the final drafting of this article. A multidisciplinary team approach, thorough assessment, meticulous preparation, and critical decision-making are essential for successfully managing a difficult airway post-mandibulectomy.
