Abstract
Infrastructure maxillectomy is a surgical procedure to remove the lower part of the maxilla and hard palate. The objective of the present study was to analyze clinical data and treatment outcome of patients who underwent infrastructure maxillectomy between 2011 and 2019. A total of 13 patients who underwent infrastructure maxillectomy for maxillary sinus and hard palate neoplasms between 2011 and 2019 were analyzed. These patients were subdivided into maxillary sinus neoplasm (n=5) and hard palate neoplasm (n=8) groups. All patients except one underwent infrastructure maxillectomy using the sublabial approach. One patient underwent an external approach through lateral rhinotomy. Postoperative reconstruction was performed for 11 patients using obturator, 6 patients using skin grafts and 3 patients using free flaps. A total of 6 patients had radiotherapy (RT), 3 had concurrent chemoradiotherapy (CCRT) and 2 had chemotherapy after surgery. The survival rate and recurrence rate were 61.5% (8/13) and 46.2% (6/13), respectively. The current results suggested that infrastructure maxillectomy may be an effective treatment for maxillary sinus neoplasms in the lower part of the maxillary sinus and hard palate neoplasms without causing marked functional or cosmetic morbidity. Postoperative RT or CCRT may be recommended to decrease the recurrence after infrastructure maxillectomy.
