Atrial fibrillation is the most common postoperative arrhythmia and can cause an increased length of stay, costs, morbidity, and mortality. Little information exists about postoperative Atrial fibrillation after major head and neck surgery, but it is thought to occur more frequently than after surgery at other extra-thoracic sites. A retrospective cohort study was implemented, including patients who had undergone major head and neck surgery and who had follow-up records covering a minimum of 60 days postoperative. The main outcome was the incidence of new-onset postoperative Atrial fibrillation after major head and neck surgery; secondary outcomes were the incidence of any Atrial fibrillation, the role of cardiology, predictors of Atrial fibrillation postoperatively, and clinical outcomes.

A total of 337 patients were included. Twenty-four patients experienced Atrial fibrillation postoperatively (7.1%), of whom 12 (3.6%) had new-onset Atrial fibrillation. New-onset Atrial fibrillation was associated with the advanced age of ?65 years and having a laryngectomy. Postoperative Atrial fibrillation following major head and neck surgery is not a rare phenomenon and can be associated with considerable morbidity and costs due to the need for intensive care, specialty consultations, additional testing, and laboratory studies, and cardiology follow-up.

7.2 \% of atrial fibrillation is not a significant factor as it can be also associated with age and its related comorbidities like hypertension and laryngectomy post radiation as carotid blow out may occur leading to mortality and manipulation of tracheooesophaheal groove may cause atrial fibrillation intra or post operatively.
