Abstract

Objective: To determine the clinical, pathological of tumor and evaluate the results of treatment by surgery Primary maxillectomy defect Reconstruction with the Titanium Plate, scapula flap and PEEK (Polyether Ether Ketone) in maxillectomy defects. Patients and Methods: A Prospective cross-sectional descriptive study, performed on 29 patients with tumor whom were diagnosed and treated at The Otolaryntology Department of K Hospital from October 2020 to October 2022. Data Collected of patients including ages and gender as well as chracteristics of tumors such as location, size, clinical stages and surgical methods. The histological classification were types, grades, TNM stages according to the American Joint Committee on Cancer (AJCC), 9^th Edition (2021). About the Flaps status were evaluated post operative and follow-up theocclusion and immediate stability of the reconstructions. Results and Conclusions: maxillectomy  defects is frequent in old age patients with an everage of 53 ± 0,13 years old. The  ratio of male / female is 1,23, bad habits such as alcohol (72,4%), smokes (51,7%), maxillectomy  defects mainly located on: ablation class III (48,7%), class III (20,7%), class II+subclass f (17,2 %), class III+subclass z (10,4 %). Pathological mainly of squamous cell of oral cavity 51,8%, sarcom 24,1%. The surgical methods are mainly used with wide resection and recontruction the defects with Titan Plate +  perforator flaps and scapular flaps (51,7%);  TitanPlate (44,8 %); Implant PEEK (3,5%). About the Flaps status were evaluated post operative: good (89,7%), flap necrosis < 1/3 (0%), totalflap necrosis (6,7%), Incision status, good (93,3%), failure (10,3%). The follow up patient shows preserved occlusion (87,2%), little malocclusion (17,2%).
