The aim of this work is the evaluation of the feasibility and outcome of levator anguli oris muscle based flaps. Methods Ninety patients of malignant nasal skin tumours were included in this study. Age was ranged from four to 78 years. For small unilateral defects affecting only one side ala nasi levator anguli oris myocautaneous LAOMC flap was used in 45 patients. For unilateral compound loss of skin and mucus membrane levator anguli oris myocautaneous mucosal LAOMCM flap was used in 23 patients. Very large defects bilateral either LAOMC or LAOMCM flaps combined with forehead glabellar flaps were used to reconstruct the defect in 22 patients. Results Wound dehiscence was the commonest complication. Minor complications in the form of haematoma and minor flap loss were managed conservatively. Partial flap loss was encountered in 6 patients with relatively larger tumours or diabetic co-morbidity three of whom were required operative re-intervention in the form of debridement and flap refashioning while total flap loss was not occurred at all. Conclusions Immediate nasal reconstruction for nasal skin and mucosal tumours with levator anguli oris muscle based flaps LAOMC LAOMCM is feasible and spares the patient the psychic trauma due to organ loss. Introduction The skin is the most common site of cancer development in humans. More than one million new skin cancer cases are diagnosed in the United States annually compared with about million
