Tumors of the nasal cavity and paranasal sinuses present a challenge to treat them. A combination of surgery and radiation therapy can improve treatment outcomes in 49-56% of patients with locally advanced nasal cavity and paranasal sinus cancer.  The midface reconstruction poses a formidable challenge to the reconstructive surgeon due to the region’s complex skeletal and soft-tissue anatomy. The rehabilitation program including the reconstruction of the resected orbital walls using the porous and mesh implants from titanium nickelid (TiNi) was developed at the Cancer Research institute jointly with the Research Institute of Medical Materials. The technique was proven effective, allowing the natural position of the eye and visual function to be preserved in 90% of patients.  A long period of reparative processes and risk of developing inflammation in the implant area, as well as the need to decrease length of surgery, contributed to the development of a novel approach to repairing the midface bone structures using the implant based on the microporous wire and TiNi mesh. Eighteen patients with nasal cavity and paranasal sinus cancer were treated using the combined thin implants. The novel technique allowed the time of the implant installation to be reduced to 5-10 minutes. The structure of the implant contributed to prevention of inflammatory processes in 97% of cases. Thus, the natural position of the eyeball and visual function were preserved in 100% of patients. The use of the TiNi implants in reconstructive surgery for patients with nasal cavity and paranasal sinus cancer led to reduced time of surgery and rehabilitation, increased level of social adaptation of patients and improved cosmetic and functional results.

Background. The majority of tumors of the nasal cavity and paranasal sinus are diagnosed at an advanced stage, requiring invasive and mutilating surgery, and therefore, the reconstruction of post-surgical craniofacial bone defects using various implants is necessary.Purpose of the study: to evaluate the effectiveness of the use of the thin-profile implants made of titanium nickelide in the surgical treatment of nasal cavity and paranasal sinus cancers.Material and Methods. From 2002 to 2020, a total of 60 patients with stage Т3–4n0–1M0 nasal cavity and paranasal sinus cancer were treated at the Cancer Research institute (tomsk). All patients received radiation therapy followed by surgery with reconstruction of bone structures of the subcranial region and orbital walls. In the study group (n=30), the orbital walls were restored with individual thin-profile shape memory titanium nickelide implants. In the control group (n=30), typical porous and tissue titanium nickelide implants were used. They required adjustment during surgery and complicated reparative processes in the postoperative period due to their thickness. Tissue implants did not allow accurate restoration of the orbital walls due to their structure.Results. Surgical rehabilitation with orbital wall reconstruction using thin-profile titanium nickelide implants makes it possible to shorten the duration of surgery and improve the precision of surgical repair. Features of the architectonics of implants do not interfere with the growth of tissues of the recipient zone, thus preventing the development of inflammation in the implantation site. The technique allows adequate restoration of the natural position and function of the eye.
