The incidence of urethral strictures in the structure of genitourinary diseases is about 6%. Treatment effectiveness, according to the literature, accounts for only 30%. The article describes the authors’ early experience of urethroplasty with free flaps of oral mucosa. Similar operations were performed for the first time in the Samara region. The stages of the surgery are described, images of surgical stages and pre- and post-operative urethrography results are presented. From the oral cavity a full-thickness mucosal flap 4×1.5 cm in size was taken. Wounds in the oral cavity were sutured, whereby uniform epithelialization without forming rough scars occurred. Through perineal access bulbar urethra with cicatricial changes was approached and mobilized. Buccal flaps were separated from underlying fatty tissue and sequentially fixed to the cavernous bodies with the separate sutures. Dorsal wall of the mobilized urethra was incised along the stricture. Bladder was drained through silicone catheter 14 Ch, above which the edges of incised urethra were sutured with the edges of transplanted mucosa. Surgical wound was sutured in layers tightly. In the late postoperative period, patients underwent urethrocopy and uroflowmetry. Good functional results were achieved.

Methods Of Reconstruction

Introduction.Due to anatomical features, surgical treatment of oral cancer can lead to significant functional and esthetic defects. Main methods of reconstruction can be divided into groups of local and free flaps. There are lots of publications devoted to reconstruction of defects of oral cavity with the use of local and free flaps, but only few of them contain the comparison of these methods in the aspect of functional results.Materials and methods.A total of 58 patients with oral cancer were included in our study. All patients received surgical treatment with one-time reconstruction of defect. In 34 cases we used free radial flap and in 24 – submental local flap.Results.The use of submental flap has advantages in the intraoperative time, time of recovery, functional results, with the same locoregional control.Conclusions.We suggest submental local flap and radial free flap to be the method of choice in reconstruction of mucosa and soft tissues defects in patients with primary and recurrent oral cancer.

Lipomatous Tumors

The purpose of this study was to determine the clinicopathological and immunohistochemical features of lipoma/fibrolipoma with rare occasions as osseous and/or chondroid differentiation in the oral cavity. Two cases of the tumors, who presented with a painless, relatively hard mass on the oral mucosa, were studied. These were consisted of a well-circumscribed mass of fatty tissue with chondroid and significant fibrous component intermixed with the lobules of fat cells with chondroid and woven bone component, respectively. Immunohistochemical study revealed that peripheral spindle cells around chondroid tissue stained diffusely for S-100 & and Sox-9, though peripheral spindle cells around osteoid tissue only stained for RUNX-2. According to review of the literature, lipoma/fibrolipoma with osseous and/or chondroid differentiation was 18 cases. Also fibrolipoma with osseous and chondroid differentiation is the first to be reported here. These results indicated that the cartilage/bone is produced by differentiation of undifferentiated mesenchymal cells of stroma.

The male urethral stricture treatment is actual clinical issue with its resolution being increasingly frequently based on application of minimum invasive therapeutic interventional uroradiology methods. Since the methodology is applied over the last two decades, the most reasonable therapeutic algorithm has not been defined yet with respect to the correlation with the contemporary surgical treatment. The results of application of the temporary covered self-expandable nitinol Allium stents, which have been applied for the first time ever at our Institution in October 2003. Over the last 3 years, the method was applied in 40 males, averagely aged 54 years with urethral strictures previously treated by urological methods. In four cases, stent placement was performed after endourethral incision. The most common etiology of the stricture was the posttraumatic (55 %), post-inflammatory (32%) and iatrogenic (10%). In all the cases, stents were removed 12-14 months after their insertions. The results are evaluated using uroflowmetry and urethrocystography, revealing in 85% of the cases permanent recanalization free of dysuric complaints. Development of a stricture on the anterior stent end was evidenced in 15% of the cases.

The study objective is to assess immediate and long-term results of replacing complex defects with a free radial forearm flap in the multimodal treatment of patients with locally advanced oral cavity squamous cell carcinoma. Materials and methods. Twenty eight patients (20 women and 8 men aged 23 to 71 years) with locally advanced oral cavity squamous cell carcinoma (including 10 buccal cancers, 8 carcinomas of tongue, 6 carcinomas of the floor of the mouth, 2 retromolar area carcinomas, 1 carcinoma of the hard palate and 1 carcinoma of alveolar region of the lower jaw) underwent tumor surgery with simultaneous plastic reconstruction of the defect using radial forearm free flap at the department of head and neck tumors of N. N. Blokhin National Medical Research Center of Oncology within 2010–2018. Primary tumors were detected in 2 patients and 11 patients had residual (n = 7) or recurrent (n = 4) tumors after radiotherapy or chemoradiotherapy. Results. An overall success rate was 96.4 %. Postoperative histology revealed that there were no tumor cells at the resection edges. Postoperative complications included: complete flap necrosis in 1 patient with severe concomitant diseases, marginal flap necrosis in 2 patients (in both cases after the necrotic tissue had rejected, wounds were healed by secondary intention), sural veins thrombosis in 1 patient, acute peptic ulcer bleeding on the 6th day after surgery in 1 patient treated with emergency endoscopic hemostasis. No lethal outcomes were reported. Postoperative period lasted in average 14 days. Upon subsequent observation tumor relapse in the oral cavity occurred in 4 (14.3 %) patients, relapses of regional metastases – in 2 (7.1 %). Good aesthetic and functional results were noted. Adequate restoration of breathing, chewing, swallowing and speaking resulted in a full patients’ rehabilitation. In all cases, the radial flap adapted well to the oral cavity organs and corresponded to the surrounding tissues in thickness and consistency. Conclusion. Use of a radial forearm free flap makes it possible to successfully reconstruct extensive and complex defects after surgery of locally advanced primary and recurrent forms of oral cavity squamous cell cancer of various locations. Due to flap’s high regenerative capabilities, preoperative radiation therapy does not affect the frequency of local complications. It allows restoring vital functions of the oral cavity and achieving good aesthetic and functional results.

Precise Diagnosis

Hemangiomas are benign neoplasms that are common in the head and neck, but relatively rare in the oral cavity. They can cause esthetic and functional impairment, depending on location. The most common site is the upper lip, but they can occur in other areas, such as the tongue, buccal mucosa and palate. Treatment is primarily dependent on correct diagnosis of the lesion and on its anatomic location. The purpose of this article is to provide a description of a case of a hemangioma on the upper lip, treated by therapeutic sclerosis with monoethanolamine oleate (Ethamolin®), covering clinical characteristics and methods for diagnosing these lesions. Precise diagnosis and appropriate therapeutic management resulted in satisfactory esthetic and functional results, with total regression of the lesion and no signs of relapse at 1-year follow-up.

The reconstruction of finger flexor tendons with vascularized flexor digitorum superficialis (FDS) tendon grafts (flaps) based on the ulnar vessels as a single stage is not a popular technique. We reviewed 40 flexor tendon reconstructions (four flexor pollicis longus and 36 finger flexors) with vascularized FDS tendon grafts in 38 consecutive patients. The donor tendons were transferred based on the ulnar vessels as a single-stage procedure (37 pedicled flaps, three free flaps). Four patients required composite tendon and skin island transfer. Minimum follow-up was 12 months, and functional results were evaluated using a total active range of motion score. Multiple linear regression analysis was performed to evaluate the factors that could be associated with the postoperative total active range of motion. The average postoperative total active range of motion (excluding the thumbs) was 178.05° (SD 50°). The total active range of motion was significantly lower for patients who were reconstructed with free flaps and for those who required composite tendon and skin island flap. Age, right or left hand, donor/motor tendon and pulley reconstruction had no linear effect on total active range of motion. Overall results were comparable with a published series on staged tendon grafting but with a lower complication rate. Vascularized pedicled tendon grafts/flaps are useful in the reconstruction of defects of finger flexor tendons in a single stage, although its role in the reconstructive armamentarium remains to be clearly established.
