Combined Techniques for Bilateral Maxillary and Nasal Reconstruction After Ablative Surgery for Adenoid Cystic Carcinoma

Abstract

Indolent tumor growth up to large tumor masses and broad infiltration of surrounding tissue are the most typical characteristics of malignant tumors of the nasal cavity and paranasal sinuses. If surgery is a therapeutic option, extended resections and complex reconstruction modalities have to be taken into account. We present a combination of different reconstruction techniques to restore midface integrity after bilateral maxillectomy, including parts of the nasal skeleton, for adenoid cystic carcinoma. After obtaining tumor-free margins, reconstruction was performed using a microvascular double-flap technique to achieve a neo-maxilla and soft tissue lining of the oral cavity, dental implantology with prosthetic restoration and the insertion of a patient-specific implant for nasal re-shaping and stability. In cases of extended maxillary resection, a combination of different techniques can achieve sufficient functional and aesthetic rehabilitation, and restore quality of life. Further studies are warranted to evaluate the long-term stability of such complex reconstructions. However, local tumor control remains the highest priority and will be essential for years.
