Dynamic Surgical Restoration of Mid and Lower Facial Paralysis: A Single-Greek-Centre Experience.

Background Facial palsy detrimentally impacts an individual's quality of life due to its effects on function and appearance. There are several reconstructive surgical techniques available that aim to restore facial symmetry. Techniques such as direct neurorrhaphy, nerve grafts, dual reanimation, and reinnervation have the potential to enable varying motor functions, including the re-establishment of a dynamic smile. This study aimed to assess the outcomes of facial palsy reconstructive surgeries undertaken at a tertiary care centre for facial nerve reconstruction in Athens. Methods This study consisted of a comprehensive case series showcasing the outcomes of facial palsy reconstructive surgeries on 29 patients at our Tertiary General Oncological Anti-Cancer Hospital of Athens 'Agios Savvas'. The surgical procedures from October 2004 to December 2023 included reinnervation, nerve grafting, free muscle transfer, and myoplasties following our recommended algorithm. We categorized the patients into two groups: Group A and Group B based on the timing of the reconstruction: delayed or immediate. The House-Brackmann grading scale evaluated the degree and improvement of facial paralysis. Results In Group A, two of the seven patients exhibited activation of the mimetic musculature immediately postsurgery, while the remaining five experienced enhanced facial nerve function in the subsequent months. Adverse outcomes were temporalis dysfunction in one case and tongue atrophy in another. Conversely, in Group B, 21 of 22 patients demonstrated facial activation immediately postsurgery. Only one patient from this group did not show any facial nerve function postoperatively. Two of the 22 patients in Group B encountered complications: one with trismus and another with temporalis dysfunction. All patients were observed for a minimum of 12 months postsurgery. Conclusion With the exception of one patient, all participants showed improved postoperative results, which were satisfactory when weighed against the observed morbidity rate. While our case analysis did not reveal any clear indication of one particular technique being superior, the selection of methods should be based on several factors, and this algorithm could serve as a useful aid in that regard. A comprehensive and standardized clinical assessment of facial palsy, both before and after surgery, is crucial to establish a consensus and plan individualized therapy.

Anatomical Considerations and Plastic Surgery Reconstruction Options of Sacral Chordoma Resection.

Introduction Chordomas are slow-growing malignant bone tumors arising from remnant embryonic notochord cells with predilection for the sacrum. They rarely metastasize, and early surgical resection with clear margins is the treatment of choice followed by plastic surgery reconstruction supplemented with adjuvant radiotherapy based on the local treatment protocol or in cases with a contaminated surgical field. Aim The aim of the present study is to present our experience in surgical management of sacral chordomas and propose a surgical reconstruction algorithm considering anatomical parameters after partial or total sacrectomy. Materials and methods  Twenty-seven patients with sacral chordomas were treated in our Orthopaedic Surgery Department between January 1997 and September 2022, and 10 of them had plastic surgery reconstruction. Patients were divided into groups based on the type of sacrectomy, sacrum anatomical vascular or neural variations, partial or total, and the type of soft tissue reconstruction. The postoperative complications and the functional outcomes in each patient were assessed. Results  Bilateral gluteal advancement flaps or gluteal perforator flaps are the first choice in patients with partial sacrectomy, intact gluteal vessels, and without preoperative radiotherapy followed by transpelvic vertical rectus abdominis myocutaneous flap or free flaps in those patients with near total sacrectomy and preoperative radiation therapy. Conclusion  There are four reliable options for patients after sacral chordoma resection: direct closure, bilateral gluteal advancement flaps, transpelvic vertical rectus abdominis myocutaneous flaps, and free flaps. Each time, tumor-free margins and a good reconstructive plan according to the defect and patient characteristics are mandatory.

Free microvascular tissue transfer for the reconstruction of midfacial defects in oncological patients

This study reviews our experience with free microvascular tissue transfer for the repair of midfacial defects insurgical oncology.From 2000 to 2008, eight patients with maxillectomy defects were immediately reconstructed using free flaps.Their clinical charts were retrospectively reviewed to record demographic data, ablative and reconstructive procedures,complications and outcome. Free tissue transfer was successful in all patients, giving an overall success rate of 100%. The mean follow-uptime was 4 to 101 months (mr: 43.8). Three patients died from the disease giving a patient mortality of 30%, whilefive patients are alive, free of disease and back to their normal daily activities. The restoration of function and improvement of patients’ quality of life was a common feature in all our reconstructions.The development of free tissue transfer has made surgical treatment of oncological patients with maxillectomy defects previously considered inoperable possible, improving at the same time their quality of life (AU)

Functional results of speech and swallowing after oral microvascular free flap reconstruction.

PURPOSE: To study speech and swallowing in patients who underwent microvascular free flap reconstruction after major surgery of the oral cavity. PATIENTS AND METHODS: Twenty patients, 17 men and 3 women, with a mean age of 58.5 years (range 27-79 years) were included in the study. Squamous cell carcinoma was the most common malignancy. Swallowing assessment was performed through videofluoroscopy, using three consistencies of barium meal. The recorded swallows were assessed for the ability to hold the bolus during the oral phase, lip seal, tongue movement, residue in the floor of the mouth, laryngeal penetration and aspiration. Speech function regarding intelligibility and articulation was objectively assessed. RESULTS: Fifteen out of 20 patients (75%) had a good lip seal. Fourteen patients (73.6%) had adequate control of bolus, while in 89.4% the neotongue motility was satisfactory. Vallecular residue was noted in 25% of patients, laryngeal penetration in two (10%), while three patients (15%) continued to have significant aspiration, which necessitated continuous feeding through a gastrostomy. Postoperative speech intelligibility and articulation was satisfactory in 75 and 62.5% of the patients, respectively. CONCLUSIONS: Microvascular free flap reconstruction of major defects after oral resections rehabilitates the functions of swallowing and speech in acceptable levels, improving quality of life in these patients.

Giant Basal cell carcinoma: clinicopathological analysis of 51 cases and review of the literature.

BACKGROUND: Giant basal cell carcinoma (GBCC) is an aggressive malignant neoplasm. Because of the rarity of the tumor and its recognized high risk of recurrence, there are no guidelines for its treatment. PATIENTS AND METHODS: Published articles in PubMed Central were carefully reviewed. Data from 48 patients obtained from 30 individual articles were added to our 3 cases, producing a total number of 51 cases of GBCC. A clinical database was established in order to define the behavior of this tumor, prognostic factors and optimal treatment. RESULTS: GBCC mostly occurs in elderly male patients, with a peak incidence in the seventh decade of life. It develops as long-standing dermal tumor with mean disease duration of 14.5 years and is most commonly located on the back, followed by the face and upper extremity. The most common histological subtype is nodular. The average size at presentation is 14.77 cm in its largest diameter. The presence of metastasis at the time of presentation represents the most significant adverse prognostic factor. Local recurrence or metastasis develops in 38.3% of patients despite optimal therapy. The overall reported cure rate is 61.7% by a mean follow-up of 2 years. Wide local excision of the tumor with or without postoperative radiochemotherapy represents the optimal treatment. CONCLUSION: Optimal management of GBCC consists of wide local excision with histologically confirmed tumor-free margins, frequently followed by adjuvant therapy. In cases of lymphatic spread, a regional lymphadenectomy is also necessary. In addition, consideration should be given to a close and long-term follow-up because of the high rate of locoregional recurrence.

Mucoepidermoid carcinoma of the salivary glands. Review of the literature and clinicopathological analysis of 18 patients.

Salivary gland carcinomas are a rare and clinically diverse group of neoplasms among which mucoepidermoid carcinomas (MEC) are reported to be the most frequently encountered. During the years 1994-2004 18 patients with MEC were treated in our Department. All patients underwent surgery with a curative intent, and in 11 of them treatment was supplemented by radiotherapy. Follow up ranged from 6 to 120 months. Twelve (66.6%) MECs originated from the major salivary glands with the majority located in the parotid. Histologically, 50% of tumors were classified as low grade, 28% as intermediate and 22% as high-grade MECs. Positive surgical margins were documented in six cases (33%) and all in tumors of high or intermediate histological grade. All these patients received adjuvant radiotherapy and one developed local recurrence. Local recurrence occurred in two more patients with histologically free margins. Both received postoperative radiotherapy. Distant metastases were documented in four patients all between 14 and 24 months after surgical treatment. An association between local recurrence and distant metastasis might be suggested since all patients with local recurrences subsequently developed distant metastases. The 5-year overall disease specific survival rate was 85%. Statistical multivariate analysis demonstrated that the factor that significantly correlated with overall survival was the histological grade of tumors (Log Rank test: p=0.013). A trend towards poorer survival was observed in patients aged over 50 years. Our results also suggested a potential benefit of postoperative radiotherapy for patients with positive margins.

Adenoid cystic carcinoma of the head and neck. Clinicopathological analysis of 23 patients and review of the literature.

Adenoid cystic carcinoma (ACC) is a rare epithelial tumor with a distinct natural history characterized by an indolent but persistent growth, late onset of distant metastases and eventual death of patients. Between 1991 and 2003, 23 patients with ACC were treated in our Department. Surgery with a curative intent followed by radiotherapy (RT) was applied in 22 patients. Complete resection was achieved in 72.73% of patients. Local recurrence occurred in 26% of patients. Positive margins emerged as the only statistically significant parameter (p < 0.0001) influencing the development of local recurrence. Distant metastasis (DM) occurred in 47.8% of patients. In 54.5% of the patients developing DM, this occurred between 5 and 10 years after the initial treatment. DM was influenced by perineural invasion (p = 0.04) and was disassociated from local control of the tumor. The mean overall survival of our patients was 70.58 months and the mean disease free survival 61.85 months. Perineural invasion (p = 0.048) and DM (p = 0.001) had a statistically significant impact on final patients' outcome. The most important factor influencing survival was DM. Its late onset, irrespectively of local control, supports the hypothesis that ACC has a potential to develop DM in the very early phases of tumor growth.

Tumors of the submandibular gland: clinicopathologic analysis of 23 patients.

PURPOSE: Tumors of the submandibular gland are rare, comprising less than 2% of head and neck neoplasia. Both benign and malignant lesions show a mild symptomatology, resulting in late presentation and in advanced stage of disease. The purpose of this article was to report our experience in treating submandibular gland neoplasia during the last 10 years. PATIENTS AND METHODS: The medical records of all patients with histologically confirmed epithelial tumors of the submandibular gland were retrospectively reviewed. This review found 23 patients with 9 benign and 14 malignant tumors. The collection of data included demographic data, diagnostic procedures, operative and pathology reports, complications, additional treatment, and follow-up. RESULTS: There were 10 men and 13 women with a mean age of 60 years. Pleomorphic adenoma was the most frequently encountered benign tumor; adenocarcinoma and adenoid cystic carcinoma had an equal presentation in the malignant group of patients. Eleven of the 14 patients with malignant tumors presented in advanced stages of disease (stage III and IV). Surgery was the sole treatment for the benign tumors. There were no recurrences. In the majority of cases, patients with malignant tumors were treated with surgery and postoperative radiotherapy. Eight patients died during the follow-up period, giving a mortality rate of 61.5%. CONCLUSION: Benign submandibular gland tumors manifest a mild course of disease, and local excision along with the gland is a safe and effective method of treatment. Malignant tumors have a poor symptomatology that results in late diagnosis. Radical surgery and postoperative radiotherapy is the treatment of choice. Prognosis depends on the histopathology and biologic behavior of the specific type of malignant tumor.
