RESUMO

AIM: The main aim of the present report is to describe a modified technique of tip scapular flap harvesting to allow 2 surgical teams to work at the same time and to shorten surgical times. MATERIALS AND METHODS: The medical records of 25 patients that had undergone maxillary or mandibular reconstruction by using a free scapular tip flap were retrospectively reviewed to identify the possible advantages and disadvantages of this type of flap. RESULTS: Thirteen patients analyzed in this series underwent maxillary reconstruction with tip scapular flap, while the other 12 patients underwent mandibular reconstruction. No failures, partial failures, or infections were evidenced in this series. Scapular tip flap allowed for acceptable esthetic and functional outcomes. In all cases, the patient was placed supine. No major complications were observed at the donor site during follow-up. CONCLUSION: Scapular tip flap might be extremely useful for head and neck reconstruction. Pedicle length, versatility, and reliability represent the major advantages of this reconstructive recourse. Moreover, the resistance of the scapular vascular system to atherosclerosis could be helpful in patients showing contraindications to free fibula flaps.

RESUMO

Many different flaps have been used for reconstruction of the oral mucosa and the maxilla and mandible after tumor resection. These flaps might contain bone and might be free or locoregional. This study presents 2 cases of intraoral reconstruction using a submental osteocutaneous perforator flap to reconstruct the maxilla in one case and the mandible in the other. A reverse-flow flap was used for maxillary reconstruction In these cases, the functional, esthetic, and oncologic outcomes were favorable at 9 and 12 months of follow-up.

RESUMO

The treatment of early-stage oral squamous cell carcinoma (OSCC) is still a controversial issue. Thanks to the 8th edition of TNM by AJCC there is a better distinction between the stages of OSCC. However, Stages I and II still share the same treatment protocol, even if the prognosis is radically different. A retrospective study has been conducted including 70 previously untreated patients with Stage I or II OSCC, treated with tumorectomy and selective neck dissection. The study focuses on the link between pT1/2 and various other factors, particularly histological grading, vascular and perineural invasion, local and cervical recurrence, surgical margins and overall survival. These data reveal significant differences between pT1 and pT2 in histological grade, perineural invasion, cervical recurrence, surgical margins, and overall survival, emphasizing the necessity of different treatment protocols for T1 and T2 OSCC. Distinct strategies should be proposed to treat Stage I and II OSCC, with Stage II patients possibly benefitting from more aggressive treatments: following these data, a wait-and-see strategy should only be considered in Stage I, while certain treatments at the cervical level - such as prophylactic neck dissection and sentinel node biopsy - should always be considered for Stage II tumors.

RESUMO

INTRODUCTION: Unlike other types of cancers, the prognostic value of histological tumor grade is not well determined for oral squamous cell carcinoma (OSCC). This study therefore aimed to evaluate the impact of tumor differentiation on prognosis and overall survival of patients affected by squamous cell carcinoma of the oral cavity. MATERIALS AND METHOD: A retrospective analysis was conducted using the records of patients diagnosed with squamous cell carcinoma of the oral cavity between 2010 and 2015. The study included 162 patients treated with a tumorectomy and selective neck dissection. The influence of histological tumor grade on several prognostic factors such as T-Stage, N-stage, recurrence rate, perineural invasion, vascular invasion, surgical margins, and overall survival was analyzed. RESULTS: Histological grade strongly correlated with N-stage, recurrence rate, perineural invasion, vascular invasion, surgical margins, and overall survival. Overall survival was 71.6% in patients with well-differentiated tumors and 43.2% in those with moderately and poorly differentiated tumors. CONCLUSIONS: Histological grade represents an important prognostic factor for OSCC. Therefore, various treatment strategies based on this histological parameter could improve the overall survival rate of patients affected by oral squamous cell carcinoma.

RESUMO

OBJECTIVES: The main aim of the present study is to analyze the differences in the clinical behavior of pT1 and pT2 oral squamous cell carcinoma of the oral cavity and the importance of tumor thickness in these groups of patients. METHODS: A retrospective analysis was conducted using the records of patients diagnosed with pT1 and pT2 oral squamous cell carcinoma between 2006 and 2015 to identify significant differences between these two groups of patients. Several pathological features such as T-stage, N-stage, tumor thickness, surgical margins, and locoregional failure were analyzed. RESULTS: 194 patients were included in this study. Tumor thickness >0.4 cm was significantly related with nodal involvement and overall survival (p < 0.001). T and N stage, tumor thickness, extracapsular spread and surgical margins were associated with poorer outcomes in terms of overall survival (p < 0.001). CONCLUSION: Tumor thickness represents an extremely important prognostic factor and to include depth of invasion (DOI) in the staging of oral squamous cell carcinoma will help in the choice of better treatment strategies and to improve overall survival.

RESUMO

Peripheral ossifying fibroma (POF) is a lesion of the gingival tissues that predominantly affects women and is usually located in the maxilla anterior to the molars. The definitive diagnosis is established by histological examination, which reveals the presence of cellular connective tissue with focal calcifications. Surgery is the treatment of choice, though the recurrence rate can reach 20%. We present a clinical and histological review - including a detailed immunohistochemical analysis - of four cases of POF diagnosed and treated at our hospital. All four patients were women, and two were pregnant. The immunohistochemical study revealed that the proliferating cells showed myofibroblastic characteristics and did not express estrogen or progesterone receptors. The lesions showed clinically benign behavior. Our results indicate that POF should be considered as a myofibroblastic proliferation, and although the clinical characteristics suggest hormonal influence, we were unable to demonstrate the expression of hormone receptors in the proliferating cellular component.

RESUMO

INTRODUCTION: Basal cell nevus syndrome (BCNS), also known as Gorlin-Goltz syndrome, comprises five main pathological features: nevoid basal cell carcinomas, keratocystic odontogenic tumors, congenital skeletal anomalies, calcification of the falx cerebri, and point skin depressions on the palms and/or soles. The disease exhibits a dominant autosomal hereditary trait, with implication of the human homologue of the Drosophila segment polarity Patched (PTCH) gene. BCNS is diagnosed on the basis of clinical and radiological criteria and can be confirmed by genetic study. The patient prognosis is very good, with normal life expectancy in most cases. METHODS: The present study reports two cases of BCNS with the presence of maxillo-mandibular keratocystic odontogenic tumors. RESULTS: One case was diagnosed according to clinical criteria, while the other required genetic confirmation that revealed a germ line mutation in exon 17 (c.2868delC), not previously described in the databases, which was considered to be responsible for the disease.
