Introduction. Surgery at the first stage has always been the gold-standard treatment for locally advanced head cancer of almost all locations. Such patients often have significant postoperative defects that cause serious functional and aesthetic disorders. This requires simultaneous defect repair. The technique of defect repair should be chosen carefully with the consideration of its benefits and potential consequences.Objective – to evaluate the efficacy of revascularized radial flaps for defect repair after combination extensive surgical excisions of head and neck tumors.Materials and methods. This study included 67 patients with head and neck cancers of different locations who had undergone surgical tumor excision followed by defect repair using a radial flap.Results. All patients had their defects repaired using radial autologous grafts. Since this study included primarily patients with oral and oropharyngeal tumors (53 patients), we also analyzed the survival in this cohort. patients were followed-up for 2 to 7 years. fourteen patients (26.4 %) developed progressive disease during this time, including 8 individuals with recurrent primary tumor and 6 individuals with regional metastases. The mean time to nasoesophageal probe removal and restored swallowing was 12.2 days; mean length of hospital stay was 13.5 days.Conclusion. Thus, radial flap is a reliable and multifunctional material that can be used to repair complex and combination defects in patients with head and neck tumors. In some cases, it is the method of choice, since it helps to achieve satisfactory quality of life. Repair of tongue defects with radial flaps ensures good functional results.
Introduction. Surgical treatment of malignant tumors of maxilla and midface results to a combined defects of the soft tissues of the face (upper lip, buccal, zygomatic regions), upper jaw, hard and soft palate, retromolar region, orbit, nasoethmoidal complex. This is one of the most difficult localizations in terms of both the possibility of performing radical surgery and reconstruction. The purpose of reconstruction is not only the elimination of cosmetic deformity, but also the restoration of such vital functions as breathing, swallowing, speech and binocular vision. Till that time, no algorithm has been developed for choosing a method for the reconstruction and there is no comparative analysis of the available methods.The study objective is to improve the functional and aesthetic results of treatment patients with malignant tumors of the upper jaw and midface.Materials and methods. For the period from 2014 to 2020 in the Department of Head and Neck Tumors of the N.N. Blokhin National Medical Research Center of Oncology, ministry of Health of Russia microsurgical reconstruction after resections of the upper jaw and midface was performed in 80 patients. most often (25 (31 %) patients) the primary tumor was localized in the maxillary sinus, then hard palate (16 (20 %) patients), soft palate (11 (14 %) patients), retromolar trigone (13 (16 %) patients). primary location at alveolar process of the upper jaw was in 3 (3 %) cases, nasal cavity and cells of the ethmoid labyrinth - in 4 (5 %), frontal sinus - in 5 (6 %), the skin of the cheek and lower eyelid - in 3 (3 %) patients. we defined 4 main types of resection. Type I - combined lower resections of the maxilla and mucosa of the retromolar region, soft palate, lateral wall of the oropharynx (47 (60 %) patients). Type II - total radical maxillectomy (resection of all walls of the upper jaw, including orbital wall) (12 (15 %) patients). In 5 (42 %) cases, the resection was combined and included, in addition to the upper jaw, the skin of the buccal and zygomatic regions. Type III - combined partial resections of the upper jaw (13 (17 %) cases). In 9 (69 %) cases, the block of tissues to be removed included a fragment of the skin of the buccal region, part of the external nose, and lower eyelid. Type Iv - orbitomaxillary resection with orbital exenteration (6 (8 %) patients), including exenteration of the orbit, cells of the ethmoid labyrinth, resection of the frontal bone, medial wall of the orbit, a fragment of the dura mater (4 (67 %) cases), skin of frontal, buccal, zygomatic areas, upper and lower eyelids. for reconstruction of defects in 80 patients we used 82 free flaps. In 76 (93 %) cases, simultaneous resections of the primary lesion and reconstructions were performed, in 6 (7 %) cases, delayed reconstruction after previously performed combined or complex treatment were performed.Results. In type I resection with limited defects excellent functional and aesthetic results were obtained in all cases of using a radialis fasciocutaneous free flap. In case of subtotal and total defects of the hard palate and the alveolar margin of the upper jaw, the best aesthetic (excellent in 5-46 % of patients, satisfactory in 3-27 %) and functional (excellent speech quality in 8 patients) results were obtained with use free scapula tip flap. In type II resections excellent aesthetic results were obtained in 6 (55 %) patients. In all cases, a chimeric free flap consists of tip of the scapula, fragment of serratus muscle and skin of parascapular region was used. In type III resections in patients with limited defects, 5 (71 %) had excellent aesthetic results, and 2 (29 %) had satisfactory aesthetic results. In all cases a radial free flap was used. In case of half defects of the upper jaw anterior-lateral thigh flap and thoracodorsal free flap was used. In all cases satisfactory aesthetic result was obtained. In type IV resections satisfactory aesthetic results were obtained in all patients.Conclusion. Preoperative computer 3D modeling is necessary in planning of reconstruction. This allows to determining the type and volume of the defect, plan optimal method of reconstruction, model the required flap geometry, making a template for harvesting flap, calculating the position and number of titanium plates for fixation, and, if necessary, print an individual mesh of the infraorbital wall.
Background. Orbitomaxillary resection includes exenteration of the orbital contents with resection of the inferior orbital and medial walls. The main goals are: reconstruction of soft tissue and bone structure defects, tamponade of the orbital cavity and/or its preparation for further ocular prosthetics, and reconstruction of the skull base defect. The purpose of the study to present the immediate results of orbitomaxillary resections in patients with malignant neoplasms of the skull base and midface. Material and methods. Between 2014 and 2020, 6 patients who previously underwent surgery for primary cancer (n=3) and recurrent cancer (n=3) were treated at the Head and Neck cancer department of N.N. Blokhin National medical Research center of oncology. To reconstruct defects after resection of bone structures (maxilla, frontal and nasal bones) and skin, a musculocutaneous alt-flap was used in 3 (50 %) cases and a fascial skin radial flap in 3 (50 %) cases. Results. The aesthetic result was assessed in 6 patients. In all cases, a satisfactory result was obtained. None of the patients who underwent resection of the dura mater followed by reconstruction had no symptoms of liquorrhea in the postoperative period. Conclusion. Flap selection depends on the defect size. In cases with a small defect size (up to 70 cm3), reconstruction with the radial fascial skin flap can be performed. If the defect size is more than 71 cm3, reconstruction with musculocutaneous alt flap can be the method of choice.
Background. Radial forearm free flap is one of the most frequently used in the head and neck reconstruction. A significant disadvantage is the appearance of the donor site. We have developed and introduced into clinical practice a V-shaped fabrication skin of the flap, which allows direct closure of the donor site and reduces morbidity. Aim. To assess the possibility of direct closure of the donor site and to reduce the morbidity of the donor site when performing the V-shaped fabrication of the skin area of the flap. Materials and methods. During the period from 2014 to 2020, the radial free flap was used in 43 cases. In 15 (35%) cases, a V-shaped fabrication of the skin area was used during flap harvest, which made it possible to carry out a direct closure of the donor site. The length of the skin area stretched from the top of the wrist, not reaching 34 cm to the elbow bend and varied from 715 cm, on average 12 cm. The width of the flap was determined by the elasticity of the forearm skin, was maximum in the middle third and varied from 2 up to 4 cm, averaging 3.3 cm. If necessary, the upper and lower edges of the skin area can be sutured together, as well as the entire medial edge of the flap. This technique increases the flap width by almost 2 times. This arrangement was applied in 8 cases. Results. When comparing the results of using the two techniques, the following data were obtained: "V-shaped" fabrication of the skin was used mainly in women (11/15 73%) for reconstruction limited defects in the retromolar region (5/15), soft (4/15) or hard palate (6/15). Most of the patients had localized T1-T2 (10/15) stage. None of the patients had any problems with the healing of the donor area. An excellent aesthetic result was obtained in all patients. In the group of standard harvest, the predominance of males was noted (17/28). Defects had a varied localization, most patients was with relapses after chemo-radiation treatment (10/28) or primary locally advanced T3-T4 stage process (6/28) 16, with a localized T1-T2 stage (11/28) 11, in one case, delayed reconstruction was performed. In all cases, the plastic of the donor site was performed with a split skin autograft. Partial necrosis of the donor site flap was observed in 9 patients (32%), in 4 cases with exposure of the flexor muscle tendon. Conclusion. As a result of the comparative analysis of the two methods, we concluded that the use of V-shaped fabrication of the skin area of the radial forearm flap allows to obtain better aesthetic results of the donor site, however, the use of this technique leads to a significant reduction in the length of the vascular pedicle and a decrease in the width of the flap.
