RESUMO

OBJECTIVE: The study's purpose was to compare the quality of life (QoL) in oncologic patients treated with different rehabilitation protocols following maxillary tumor resections. PATIENTS AND METHODS: The patients were divided into three groups. Group A: 18 Patients with maxillary obturator prosthesis. Group B: 17 Patients with simultaneous autologous tissue reconstruction. Group C: 12 Patients with prosthesis on zygomatic implants. The post-operative QoL was compared using standard questionnaires, investigating items like pain, mood, social relations, and specific functions that could potentially compromise the post-operative QoL. A secondary analysis compared reconstructed vs. non-reconstructed patients. RESULTS: Most questionnaire items did not show significant differences among groups. Statistically significant outcomes were found in two parameters (social contact and sexuality), in which patients treated with zygomatic implants had the best satisfaction, and patients with obturator prostheses showed the lowest satisfaction. Patients belonging to the non-reconstructed group showed better moods than those in the reconstructed group, while taste problem complaints and pain were lower in the reconstructed group. CONCLUSIONS: Although the type of reconstruction procedure depends on the type of maxillectomy to be performed and on the general health situation of each patient, the impact of the rehabilitation protocol on the patients' QoL should be accounted for when planning the treatment.

RESUMO

BACKGROUND: The purpose of the current study was to report on the clinical presentation and radiologic features of 155 cases of ameloblastoma (AB), representing a detailed, large, single-centre radiologic study. METHODS: Histologically confirmed cases were reviewed over 11 years. Demographic and clinical data were retrieved from the patient's records. Radiologic information was analysed from available radiographs. The radiologic features of ABs were assessed according to the mean age of presentation and the mean duration of the lesion. The distinguishing radiologic features between adults/children and sex were also evaluated. RESULTS: A statistically significant correlation existed between loss of border demarcation and advanced mean age. Multilocular lesions were markedly more common in adults compared to children. Multilocular ABs were associated with increased lesion duration and advanced mean age. Radiologic signs of reactive bony changes associated with the tumour presented at the highest mean duration of all bony effects. Bony expansion and cortical destruction were statistically correlated with lesion duration. Tooth impaction was more common in children. Some mandibular lesions reached a significant size, resulting in impingement of the maxillary sinus, zygoma, orbit and pterygoid plates. CONCLUSION: Due to unfortunate healthcare access constraints, ABs grow to significant sizes and exhibit features not often reported in the literature. The findings of this analysis highlighted the radiologic features of ABs expressed through the mean age and duration of the lesion. This emphasises the significance of timely management of these lesions.

RESUMO

Neoplasms of the maxilla have multiple different origins and histology, and often extend towards the infratemporal fossa, orbit, or skull base. Extensive resection may be required, often leading to poor esthetic and functional results. Usually, these lesions are removed via a transfacial approach. The aim of this study was to compare the outcomes of the transoral versus transfacial approach for maxillary tumors. A single-institution retrospective study was conducted on patients with maxillary-midface tumors, treated between January 2009 and December 2019. The patients were divided into two groups according to the surgical approach, transfacial or transoral, and the following outcomes were assessed: extent of the resection based on Brown's classification; postoperative pathology margin assessment; reconstruction technique; esthetic/functional results. A total of 178 patients were included. A satisfactory resection was obtained in both groups, with the transoral cohort achieving a higher rate of clear oncological margins (positive margins: transoral group 3.7% versus transfacial group 6.8%, P = 0.389) and a significantly higher University of Washington Quality of Life score (mean 72.2 versus 67.8, P < 0.001). Even large and invasive tumors can be treated successfully with the transoral approach, avoiding unesthetic facial scars while still providing complete resection of the tumor.

RESUMO

A real-time 3D Telemedicine system - leveraging Microsoft's Holoportation™ communication technology - enabled an international multidisciplinary team meeting (MDT) to consult with complex reconstructive patients before, during, and after an overseas surgical collaboration. METHODS: A proof-of-concept international 3D MDT clinic took place in November 2022, between the Canniesburn Plastic Surgery Unit, UK, and the National Reconstructive Plastic Surgery and Burns Centre, Korle Bu Teaching Hospital, Ghana. The 3D system was utilised 1) previsit to assess patients and enable logistical planning, 2) on-site in Ghana to further allow patients to see themselves and proposed operations in 3D, and 3) post visit to debrief the team and patients. RESULTS: Four Ghana patients were followed through their patient journey (mandibular ameloblastoma, sarcoma thigh, maxillary tumour, sarcoma back). Thirteen participants (four patients, four Ghana clinicians, and five UK clinicians) completed feedback on the 3D MDT. Outcome measures were rated highly with satisfaction 84.31/100, perceived benefit 4.54/5, overall quality 127.3/147 (Telehealth Usability Questionnaire), and usability 83.2/100 (System Usability Scale). These data show close alignment with that previously published on high-income countries. CONCLUSIONS: This novel technology has the potential to enhance the delivery of overseas surgical visits to low-to-middle-income countries, by improving planning, informed discussion with patients, expert consensus on complex cases, and fostering engagement with professionals who may be thousands of miles away. This is the first demonstration that real-time 3D Telemedicine can both work, and enhance care within an international MDT clinic, and may thus enable change in the approach to overseas surgical collaborations.

RESUMO

Unilateral total maxillectomy is indicated for locally advanced maxillary tumors that require complete removal of the midface bony structure and inferior orbital rim. Reconstruction of this defect is challenging due to aesthetic and functional concerns. A retrospective review of patients at two tertiary-care institutions undergoing unilateral total maxillectomy reconstruction with a stacked fibula flap from 2018 to 2022 was performed. Each patient's clinical course was reviewed, and attention was focused on the demonstration of surgical steps with photos. Twenty patients underwent stacked fibula flap reconstruction for unilateral total maxillectomy orbital preservation defects. Surgical extirpation was performed for malignancy (80%, 16/20) and for osteoradionecrosis or benign tumor in 20% (4/20). The complication rate was 30% (6/20). Most flaps survived (95%, 19/20). We present a modified, reproducible method of fibula flap reconstruction for unilateral total maxillectomy with orbital preservation that only requires two segments and maintains positive aesthetic and functional results.

RESUMO

Objective: To analyze the long-term quality of life of patients with Brown Ⅱ maxillary defect repaired by tissue flap or prosthesis. Methods: Patients who underwent surgery for maxillary malignant tumors in the First Affiliated Hospital of Bengbu Medical College from 2014 to 2017 were selected to investigate the postoperative long-term (>5 years) quality of life using the fourth edition of the University of Washington quality of life questionnaire (UW-QOL). Mann Whitney U test was used to examine the differences between two groups. Results: In this study, 4 cases were lost to follow-up, 9 died, and a total of 46 valid questionnaires were collected, including 24 males and 22 females, aged 19-86 years. There were 26 cases of class Ⅱb/c and 20 cases of class Ⅱd. Tissue flap reconstruction was performed in 29 cases (tissue flap group) and prosthesis restoration in 17 cases (prosthesis group). The score of chewing QOL in the prosthesis group was higher than that in the tissue flap reconstruction group (Z=-2.787, P=0.005), but the scores of entertainment, swallowing, speech and emotion QOL in the former group were respectively lower than those in the latter group (Z=-3.185, -2.091, -2.556 and -1.996, respectively, all P values<0.05). In patients with Brown Ⅱb/c defect, the prosthesis repair could improve the chewing QOL score (Z=-2.830, P=0.005), but no statistically significant differences in other QOL scores between two groups. In patients with Brown Ⅱd defect, the tissue flap reconstruction could improve the scores of pain, entertainment, swallowing and speech QOL (Z=-2.741, -2.517, -2.320 and -2.843, respectively, all P values<0.05), and the average QOL score in tissue flap reconstruction group was also higher than that of the prosthesis group (Z=-2.276, P=0.023). Conclusion: For postoperative long-term quality of life, both prosthesis and tissue flap reconstruction can offer satisfactory results in patients with Brown Ⅱb/c defect, and patients with Brown Ⅱd defect repaired by tissue flap reconstruction have better speech and swallowing functions. Tissue flap reconstruction may bring more entertainment and emotional benefits.

RESUMO

OBJECTIVE: To describe a naso-facial reconstruction technique following bilateral rostral maxillectomy and its functional and cosmetic outcomes. ANIMALS: Two dogs. STUDY DESIGN: Clinical case series. METHODS: Two dogs were presented with a right rostral maxillary mass. Preoperative biopsy and staging revealed a biologically high-grade and histologically low-grade fibrosarcoma (Hi-Lo FSA). A combined nasal planectomy and radical bilateral rostral maxillectomy was performed sparing the labial/buccal mucocutaneous flaps bilaterally. Surgery resulted in asymmetry of the width of the flaps; the narrower flap was rotated medially to reconstruct the lip and create an oral vestibule. The wider flap was rotated medially to cover the remaining dorsolateral opening of the nasal conchae. The flaps overlapped in a parallel manner, discretely concealing the nasal passages, and separating them from the oral cavity. Hemorrhage occurred in both dogs, with one dog requiring a blood transfusion postoperatively. RESULTS: Oral Hi-Lo FSA with tumor-free margins was confirmed in both dogs. Both dogs recovered uneventfully within 4 weeks. Owners reported being very satisfied with the functional (return to normal exercise/activities and uncompromised respiration) and cosmetic outcomes. Based on the owners' telephone follow up, no tumor recurrence was noted at 15 (Dog 1) and 6 (Dog 2) months postoperatively. CONCLUSION: The full-thickness bilateral labial/buccal rotational flaps were used successfully to reconstruct the rostral maxilla, external nose and facial defects involving the nasal cavity. The technique resulted in acceptable functional and cosmetic outcomes and can be considered for naso-facial reconstruction in selected cases.

RESUMO

Skeletal grafts are usually required to reconstruct defects after maxillectomy for acceptable aesthetic and functional results. Postoperative infection is a serious complication; however, few studies have evaluated the vulnerability to infection of various skeletal reconstructive materials used for maxillary reconstruction. A retrospective study was conducted on 53 cases in which maxillary skeletal reconstruction was performed between 2010 and 2021. The postoperative infection rate was compared between various skeletal reconstructive materials, including costal cartilage, scapula, fibula, ilium, cranium, and titanium mesh. In addition, the risk factors for postoperative infection were evaluated using 2-group comparison tests. Of 53 patients, 14 (25.4%) contracted an infection postoperatively. No significant differences were observed in the infection rates among the materials used for skeletal reconstruction. Cases undergoing secondary reconstruction tended to have a higher infection rate (34.4%) than primary reconstruction (14.3%). For nonvascularized skeletal grafts (41 cases), the concomitant use of soft-tissue flaps decreased the infection rate from 30.8% to 17.9%. Costal cartilage was the most frequently used material (31 cases), primarily for orbital floor reconstruction. Regarding the costal cartilage, nasal wall reconstruction had a higher infection rate (100%) than reconstruction of other parts of the maxilla (0.0%-17.9%). Nonvascularized skeletal grafts, mainly costal cartilage grafts, were safely used for maxillary reconstruction. However, caution should be exercised for postoperative infection in secondary cases and in cases where costal cartilage is used for nasal wall reconstruction. Covering nonvascularized skeletal grafts with soft-tissue flaps may be an effective countermeasure.

RESUMO

We report a case of ultrasound-guided craniocervical nerve blocks performed with ropivacaine for perioperative local/regional anesthesia in a patient who underwent right partial maxillary resection and neck dissection under general anesthesia. The patient was an 85-year-old woman with multiple medical comorbidities in whom analgesia using nonsteroidal anti-inflammatory drugs and opioids was expected to increase the risk of postoperative complications. Bilateral ultrasound-guided maxillary (V2) nerve blocks and a right superficial cervical plexus block were performed, which provided adequate perioperative anesthesia and avoided postoperative complications. The use of ultrasound-guided craniocervical nerve blocks with ropivacaine can be an effective approach for providing prolonged perioperative local anesthesia and analgesia, minimizing the need for other potentially problematic analgesics.

RESUMO

Caracterizar las lesiones cervicofaciales tumorales y pseudotumorales en niños en Villa Clara es una necesidad creciente por las alteraciones físicas, estéticas y psicológicas que pueden ocasionar. Se realizó un estudio transversal y descriptivo en el Servicio de Cirugía Maxilofacial Pediátrico de esta provincia, en el período 2010-2019. La población estuvo constituida por 101 niños con estudio histológico concluyente de lesión tumoral benigna, maligna o pseudotumoral de la región cervicofacial. Se concluyó que los tumores y pseudotumores en la región cervicofacial no tuvieron relación con la edad, género, ni color de la piel, en los niños estudiados. En esta serie predominaron los tumores benignos. El tumor maligno de mayor prevalencia fue el Linfoma de Burkitt. Existió alta correlación entre los diagnósticos clínico e histológico.


Characterizing tumoral and pseudotumoral cervicofacial lesions in children in Villa Clara is a growing need due to the physical, aesthetic and psychological alterations that they can cause. A cross-sectional and descriptive study was carried out in the pediatric maxillofacial surgery service of this province from 2010 to 2019. The population consisted of 101 children with conclusive histological study of benign and malignant tumoral or pseudotumoral lesions of the cervicofacial region. We concluded that tumors and pseudotumors in the cervicofacial region were not related to age, gender or skin color in the studied children. In this series, benign tumors predominated. The most prevalent malignant tumor was Burkitt's lymphoma. There was a high correlation between clinical and histological diagnoses.

RESUMO

BACKGROUND: Reconstruction of the maxillary defects following tumor ablation remains to be a challenge for surgeons. Virtual surgical planning (VSP), intraoperative cutting guides and stereolithographic models provides the head and neck reconstructive surgeon with powerful tools for complex reconstruction planning. Despite its use in fibular osteocutaneous reconstruction, application to the scapular free flap has not been as widely reported. The aim of this study was to compare aesthetic results and operation time of free scapular flap, with and without computer-aided design and computer-aided manufacturing (CAD/CAM) customized osteotomy guide, for reconstruction of maxillary defects. METHODS: In this prospective randomized controlled clinical trial study, we randomly assigned 22 patients with maxillary defects who were scheduled to undergo maxillary reconstruction with either free scapular flap with CAD/CAM customized osteotomy guide; study group (n = 11) or free scapular flap without CAD/CAM customized osteotomy guide; control group (n = 11). All patients were followed up for 3 months. The aesthetic outcome, operation and ischemic times were evaluated and compared. RESULTS: Aesthetic outcomes were evaluated objectively by means of differential surface area (sagittal and axial) measurement, which showed improved aesthetic outcome (contour symmetry) in the study group with a mean of (241.39 ± 113.74 mm2), compared to patients in control group with a mean of (358.70 ± 143.99 mm2). There were significant differences between the two groups (P < 0.05). Aesthetic outcomes were also evaluated subjectively by means of visual analogue scale (VAS) and patient's satisfaction score (PSS). The postoperative aesthetic appearance was better in the study group with more patients satisfied than that in control group and there were statistically significant differences (P = 0.039). The mean total operative time was 678.81 min and 777.18 min in the study group and control group respectively (P < 0.05) and the mean ischemia time was 133.18 min and 195.72 min for study group and control group respectively (P < 0.05). The ischemia time and total operative time were shorter in the study group compared to those in the control group and there were no flap losses in both groups. CONCLUSION: The use of CAD/CAM prefabricated cutting guides facilitates scapular flap molding and placement, minimizes ischemic time and operating time as well as improves aesthetic outcomes.

RESUMO

Maxillary myxomas are rare benign odontogenic tumors with a high potential for infiltration and destruction. Clinical and radiological manifestations are variable and non-specific and often lead to confusion with other benign and malignant lesions. We present here two cases of odontogenic myxoma of different localization (maxilla and mandible). In both cases, the patient presented with a progressively enlarging facial swelling without any neurologic disturbance or lymph nodes. On computed tomography, the lesions appeared as a large unilocular, homogeneous image causing a cortical thinning and rupture along with repression of surrounding tissues. The clinical and radiological features were poorly suggestive of precise nature, and only histological examination of biopsy specimen was able to reveal the diagnosis of myxoma. Given the large size of the tumors and the locally aggressive pattern, we have opted for large maxillecetomy and marginal mandibulectomy. In conclusion, myxoma is a slow growing but locally aggressive tumor that the clinician should keep in mind. As there is a lack of consensus regarding their treatment, we can suggest a conservative treatment for small non-extensive lesions, which consists of enucleation and curettage of the tumor; and a radical excision in case of large tumors given the high risk of recurrence.

RESUMO

OBJECTIVE: The aim of this systematic review was to determine the computed tomographic (CT) imaging characteristics of maxillary and mandibular melanotic neuroectodermal tumor of infancy (MNTI). Two cases from our institution were also presented. STUDY DESIGN: Full-text case reports and case series of histopathologically proven gnathic MNTI with CT figures of diagnostic quality were searched in PubMed, Scopus, Web of Science, Ovid, and Google Scholar databases from July 2021 to February 2022. Descriptive statistics were used to determine the frequency of each CT feature of gnathic MNTI. RESULTS: Fifty-two published studies met the eligibility criteria, providing a total of 53 maxillary and mandibular MNTIs for analysis. In order of frequency, the CT features of gnathic MNTI that were present in over half of the study sample were bone expansion (53, 100%), a well-defined periphery (49, 92.5%), tooth displacement (45, 84.9%), and a bilocular radiolucent internal pattern (32, 60.4%). CONCLUSIONS: The bilocular radiolucent internal pattern has not been recognized as a common CT feature of gnathic MNTI. When associated with a well-defined, expansile mass in the infantile maxilla or mandible, this imaging characteristic can support a radiologic interpretation of MNTI.

RESUMO

INTRODUCTION: Benign intraosseous maxillary tumors, although uncommon among the adolescents, represent a major challenge to the maxillofacial surgeons. Treatment ranges from conservative surgery to radical resection and reconstruction. Maxillary defect reconstruction in adolescents is uncommon. it can be achieved by prosthetic obturators, local and regional flaps, and free-tissue transfer. AIM OF THE WORK: To investigate the clinical and pathological patterns, treatment, and outcome of benign intraosseous maxillary tumors in adolescents. PATIENTS AND METHODS: A 10-years prospective study included patients between 12-18 years who presented with benign intraosseous maxillary tumors and surgically treated (conservative surgery or radical resection) with immediate reconstruction. Cases were followed up to assess functional and aesthetic outcomes and detect complications. RESULTS: Study included 38 patients; 63.2% had non-odontogenic tumors and 36.8% had odontogenic tumors. The most common non-odontogenic tumor was central giant cell granuloma (31.6%). The most common odontogenic tumors were adenomatoid odontogenic tumor and ameloblastoma (10.5% each). Treatment included Conservative surgery (55.3%) and radical resection (44.7%). Reconstruction was performed in 17 cases by temporalis muscle flap (9.83%), obturator (2.46%), and free fibula flap (1.64%). All cases gained accepted functional and esthetic results. CONCLUSIONS: Non-odontogenic tumors were more common than odontogenic tumors. Central giant cell granulomas and ossifying fibromas were the most common non-odontogenic tumors. Ade-nomatoid odontogenic tumor and ameloblastoma were the most common odontogenic tumors. Maxillary reconstructions with tem-poralis muscle flap and obturator were simple and satisfactory. Microsurgical reconstruction had high success rates. Aesthetic, and functional results were satisfactory when appropriate reconstruction was performed.

RESUMO

La reconstrucción posterior a una cirugía oncológica resectiva maxilar es todo un desafío. Debido a esto, existen diversas técnicas quirúrgicas cuyo objetivo apunta a mantener no solo la funcionalidad, sino también la estética facial, especialmente en el área del reborde infraorbitario. El injerto de hueso calvarial es una opción segura y versátil para realizar una reconstrucción primaria en el reborde infraorbitario. Esta técnica está indicada en aquellos pacientes en los cuales la resección cutánea y exenteración orbitaria no son necesarias. Por este motivo, a continuación, analizaremos este tipo de injerto a propósito de un caso clínico en el que se usó asociado a un colgajo pediculado de fascia temporoparietal.


Reconstruction after maxillary resective oncological surgery is a challenge. Because of this, there are many surgical techniques whose objective is to maintain not only function but also facial aesthetics, especially in the infraorbital rim area. The calvarial bone graft is a safe and versatile option to perform a primary infraorbital rim reconstruction. This technique is indicated in those patients in whom skin resection and orbital exenteration are not necessary. For this reason, we will now analyze this type of graft in relation to a case in which it was used associated with a temporo-parietal fascia flap.
