Introduction:Carcinomas of the paranasal sinuses are uncommon,accounting for approximately 0.8% of all cancers and 3–5% of malignant tumors in the head and neck region.Among these,the maxillary sinus is the most frequent site for primary malignant tumors. Case:A 48 year-old male,presents with nasal congestion,headache,throbbing pain and tightness in the left cheek,swelling of the left gingivae. Examination:Swelling with tenderness observed in the left cheek,zygomatic,and mandibular regions.Rhinoscopy revealed deviation of the nasal septum towards the right and a mass in the left nasal passage.The left gingivae appeared red and swollen. Diagnosis CT:Mass measuring approximately 6.8×4.9×5.4 cm with an irregular structure and a soft tissue density of+35 to +40 HU is observed,occupying the entire left maxillary sinus. Core needle biopsy:Positive for malignancy,The possibility of squamous cell carcinoma is considered Biopsy:Squamous cell carcinoma,non-keratinizing.Moderately differentiated. Conclusion The free ALT flap with or without fascia lata to repair the orbital floor is safe, reliable, and acceptable for reconstructing total maxillectomy defects.
