Application of anatomy unit resection surgery for lateral basicranial surgical approach in oral squamous carcinoma. BMC Oral Health 2023; 23:9. [PMID: 36611157 PMCID: PMC9826594 DOI: 10.1186/s12903-023-02708-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 01/03/2023] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND The basicranial region lacks definite boundaries and includes various anatomical units. We developed a novel concept of the posterior oral anatomical complex (POAC) to identify these anatomical units in the basicranial region. OSCC with POAC involvement is termed posterior oral squamous cell carcinoma (POSCC) with poor prognosis. The principal aim of this study was to evaluate the effect of anatomy unit resection surgery (AUSR) on patients with POSCC. METHODS A total of 120 POSCC patients who underwent radical surgical treatment were recruited for this study. These POSCC patients were treated with conventional surgery or AUSR. According to the extent of primary tumor resection in the AUSR group, the lateral basicranial surgical approach can be subdivided into four types: face-lateral approach I, face-lateral approach II, face-median approach or face-median and face-lateral combined approach. Facial nerve function was evaluated according to the House-Brackmann Facial Nerve Grading System. RESULTS The overall survival rate was 62.5% and 37.5% in the AURS group and conventional group (hazard ratio: 0.59; p < 0.0001), respectively. The disease-free survival rate was 62.5% and 34.3% in the AURS group and conventional group (hazard ratio: 0.43; p = 0.0008), respectively. The local disease control rate in the AURS group (71.4%) was significantly better than that in the conventional group (34.4%) in present study (p < 0.0001). Compared to the conventional group, all the patients undergoing AURS were classified as T4 stage and presented with more lymph node metastasis (71.4%). A total of 20 patients (face-lateral approach I and face-lateral combined approach) were temporarily disconnected from the temporofacial branch of the facial nerve. Fifteen patients exhibited slight paresis, and five patients presented with moderate or severe paresis. The survival rate of zygomatic arch disconnection was 94.6% (54 of 56 patients). CONCLUSION This lateral basicranial surgical approach based on AUSR improves the survival rate and enhances the local control rate while also preserving a good prognosis without damaging the nerve and zygomatic bone. This surgical approach based on AUSR provides a novel and effective surgical treatment to address POSCC with better prognosis, especially for patients without metastatic lymph nodes.

Abstract
OBJECTIVE Primary site is considered an important prognostic factor for cutaneous malignant melanoma (CMM); however, opinions vary regarding its influence on survival. This study compares overall survival between head and neck melanoma (HNM) and melanoma of other regions (MOR), as well as between melanoma of the scalp and neck (MSN) and melanoma of other head regions (MOHR). STUDY DESIGN Level III retrospective cohort study. SETTING Patients from Commission on Cancer-accredited cancer programs affiliated to the National Cancer Database (NCDB). METHODS Patients with HNM (MSN and MOHR included) and MOR, stages I to IV (n = 39,754), and their linked survival data using the NCDB were identified. Survival was analyzed using propensity score matching methods. RESULTS After matching using propensity scores, allowing this observational study to mimic a randomized controlled trial, subjects with HNM showed a 22% increased mortality when compared to MOR (P < .01). Among those with HNM, hazard was not proportional over time. Overall, subjects with MSN in the first 3.5 years of follow-up (75% of subjects) showed a 15% increased mortality when compared to MOHR (P < .01); however, after 3.5 years, no difference in survival was noted (P = .5). CONCLUSION Patients with HNM showed a higher mortality when compared to MOR. The risk of death of primary sites within the head and neck varies over time, showing a higher risk of mortality for scalp and neck during the first 3.5 years of follow-up. This increased risk was not evident after the 3.5-year threshold. Further research is needed to evaluate additional patient factors or differences in treatment approaches.

Abstract
Objectives Complex lateral skull base defects resulting from advanced or recurrent oral cancer resection are continuously challenging reconstructive surgeons. This study aimed to use reconstructive methods for lateral skull base defects, explore their feasibility, and evaluate the efficacy of defect reconstruction using anterolateral thigh (ALT) flaps. Patients and Methods We performed a retrospective case series of 37 patients who underwent lateral skull base defect reconstruction using the ALT/anteromedial thigh (AMT) flap between March 2016 and May 2021 at the Second Xiangya Hospital. The design and harvest of the flaps, methods for defect reconstruction, and reconstructive efficacy are described. Results Of the 37 patients, 3 were women and 34 were men, with a mean age of 51.7 years. Among the defects, 26 were through-and-through defects and were reconstructed using ALT chimeric flaps, double ALT flaps, folded ALT flap, combined ALT chimeric flaps and AMT flaps, or combined ALT chimeric flaps and pectoralis major flaps; the large lateral skull base dead spaces were filled with muscle tissues or fatty tissues. Postoperatively, 38 of the 39 ALT/AMT flaps survived completely, and the remaining flap experienced partial necrosis. Venous compromise occurred in one patient who was salvaged after operative exploration. Oral and maxillofacial wound infections occurred in two patients, salivary fistula in three patients, and thigh wound effusion in three patients. The wounds healed gradually in all patients after repeated dressing changes. Thirty-three patients were followed up for approximately 3–60 months; their oral functions and appearance were acceptable, and thigh motor dysfunction was not observed. Conclusions With the convenient flap design and muscle flap harvest, large and individualized tissue supply, feasible combination with other flaps, effective reduction or avoidance of wound complications, and acceptable donor site morbidity, the ALT flap is an appropriate choice for complex lateral skull base defect reconstruction.

Abstract
OBJECTIVES The aim of this study was to evaluate the feasibility and efficacy of the femoral artery (FA)-nourished anteromedial thigh (AMT) flap for reconstructing oral and maxillofacial defects. PATIENTS AND METHODS The authors analyzed a retrospective case series of 13 patients who underwent the reconstruction of oral and maxillofacial defects with the FA-nourished AMT flap. The flap design and the methods for defect reconstruction are described, and the reconstructive efficacy is reported. RESULTS Of the 13 patients, 12 were men, and 1 was woman, with an average age of 52.2 years. Of these FA-supplied AMT flaps, 7 were singly used, 5 were combined with the anterolateral thigh (ALT) flap or its chimeric flaps, and 1 was separately used with the ALT flap. Postoperatively, all flaps survived completely, without vascular compromise or major wound complications. CONCLUSIONS The FA-nourished AMT flap can also be used to reconstruct some common oral and maxillofacial defects, especially as a new alternative to the ALT flap. In addition, this flap can be combined with the ALT flap or its chimeric flaps or separately used with the ALT flap for the reconstruction of complex defects.

Abstract
The aim of this study was to better understand posterior oral cavity cancer (POCC) and its surgical treatment. This was a retrospective study of 76 patients who were diagnosed with POCC and underwent surgical treatment. Twenty-eight patients were treated with anatomical unit resection surgery (AURS) and 48 patients with conventional surgery. After initial treatment with curative intent, the patients were followed-up regularly with clinical examinations and imaging; the median duration of follow-up was 30.9 months (range 2-67 months). The 3-year overall survival was 64.3% in the experimental AURS group and 39.6% in the conventional surgery control group (hazard ratio 0.49, 95% confidence interval 0.26-0.93; P=0.031). The 3-year disease-free survival was 64.3% in the experimental group and 37.5% in the control group (hazard ratio 0.53, 95% confidence interval 0.27-1.02; P=0.114). In conclusion, AURS is an effective surgical treatment for POCC that can considerably improve patient survival rates.

Abstract
The objective of this study was to evaluate whether the extent of tumor resection and free flap reconstruction influences functional outcome and complications in patients with solid malignancies of the cheek. Therefore, we retrospectively assessed recipient site complications and functional outcomes in 47 patients with solid malignancies of the cheek who underwent either partial (n = 30; 63.8%) or full-thickness (n = 17; 36.2%) cheek resection with free flap reconstruction. Complications occurred in 12 (70.6%) patients after full thickness resections with creation of through-and-through defects compared to 14 (70.6%) patients with partial defects (p = 0.138). Among those 26 patients (55.3%), major recipient site complications, like development of salivary fistula or free flap loss, were observed in 10 (21.3%) and 2 (4.3%) cases, respectively, while minor complications, like wound dehiscence and local infections, were found in 14 (29.8%) and 9 (19.1%) patients. Complications were noticed particularly after reconstruction of suborbital defects (69.2%; p = 0.268), of which occurrence of salivary fistulae was the most common (46.2%; p = 0.035). Similarly, functional outcomes including oral incompetence, ectropion, and trismus were not affected by the extent of resection (p = 0.766). However, oral incompetence was higher in patients with tumors originating from the oral cavity (p = 0.020) and after the performance of mandibulectomy (p = 0.003). Overall, there was no difference in functional outcome or recipient site morbidity between tumor resections resulting in full-thickness and partial defects.

Abstract
PURPOSE Radical resection of buccal carcinoma frequently leads to intraoral or through-and-through buccal defects. Anterolateral thigh (ALT) flaps can be harvested to reconstruct different buccal defect subtypes. The purpose of this study was to investigate clinical outcomes after the application of personalized ALT flaps for the precise reconstruction of unilateral buccal defects. MATERIALS AND METHODS Patients with primary unilateral buccal carcinoma who underwent tumor ablation and simultaneous reconstruction of personalized ALT flaps from January 2015 to January 2018 were enrolled in this retrospective case series. Buccal defects were classified into 4 subtypes. Demographic features, defect range and reconstructive method, and perioperative characteristics were reviewed and recorded. Quality of life and mouth opening were assessed by the University of Washington Quality-of-Life questionnaire and interincisal distance (IID), respectively, during follow-up. Descriptive statistics were calculated for each study variable. RESULTS Four types of ALT flaps were harvested and used to reconstruct different buccal defects in 146 patients. Of the 193 skin paddles applied, 189 survived, and few recipient- and donor-site complications were observed. One hundred eight patients were assessed with the University of Washington Quality-of-Life questionnaire and followed until 12 months postoperatively. Our results showed that physical, functional, social, and emotional domain scores increased steadily during the follow-up period. Ninety-eight patients showed improvements in mouth opening when the IID before the operation was compared with the IID at 3 and 6 months postoperatively. CONCLUSIONS A personalized ALT flap is a suitable choice for reconstructing unilateral buccal defects after oncologic surgery given its high success rate, customizable and flexible design, low complication rate, and satisfactory esthetic and functional results.

Abstract
OBJECTIVES To evaluate the oncological safety and reliability of the submental island flap (SIF) technique in patients with pathologically node-negative (pN0) and node-positive (pN+) T1-2 oral squamous cell carcinoma (OSCC) undergoing surgical tumor resection and concurrent SIF reconstruction. PATIENTS AND METHODS Retrospectively, we reviewed patients with pN0 and pN+ T1-2 OSCC who underwent tumor resection and defect reconstruction with SIF from April 2008 to September 2016, focusing on flap viability, patterns and predictors of locoregional failure, salvage treatments, and oncologic prognosis. RESULTS Of 160 patients with primary T1-2 OSCC, 33 were pN+ and 127 were pN0. All SIFs beside two were successful (98.75%). During follow-up, 18 patients experienced locoregional tumor relapse, of which 14 were pN0 and four were pN+. The 5-year recurrence-free survival was 88.73% vs. 86.93% for the pN0 and pN+ groups, respectively (p = .847). The pN + patients had poorer prognosis than pN0 patients (5-year overall survival, 66.35% vs. 91.10% respectively [p = .005]; disease-specific survival, 74.87% vs. 91.88% respectively [p = .016]). Multivariate analyses indicated there was no independent predictor for locoregional recurrence, but pN+ was predictive for poor prognosis (p = .03). CONCLUSION SIF is a reliable flap for the reconstruction of OSCC-related small- and medium-sized soft tissue defect. With careful neck dissection and appropriate postoperative adjuvant treatment, the application of SIF did not increase the risk of locoregional tumor recurrence in patients with pN+ T1-2 OSCC compared with those with pN0 T1-2 OSCC.

Abstract
OBJECTIVE This study investigated the feasibility and clinical result of radical resection of posterior buccal carcinoma by using the facial nasolabial fold "smile" incision approach. METHODS From August 2016 to March 2017, 23 patients with posterior buccal carcinoma were included in this study and underwent radical surgery. Upon finishing the cervical lymph node dissection, an arc-shaped incision was made at 1 cm lateral to the ipsilateral angulus oris, extending along the nasolabial fold upward to the inferolateral margin of the nasal alar while downward in direct continuity with the neck dissection incision. RESULTS Satisfactory exposure and easy resection of the primary tumor with negative surgical margin were achieved in all 23 patients. After 12-22 months of follow-up (16.5 months on average), all patients recovered favorably, and no local recurrence or distant metastasis was observed. Mouth opening was restored to normal in all cases. The scars were hidden in the nasolabial fold, thus named "smile" incision. CONCLUSIONS For posterior buccal cancer patients, the facial "smile" incision approach can satisfy the need of surgical exposure, facilitate operative performance, and preserve the annular integrity of the lips without affecting the radical tumor ablation, thereby maintaining a favorable mouth opening. With these advantages, the "smile" incision approach is considered worthy of being popularized in clinical application.

Abstract
PURPOSE Studies on coagulation parameters (including activated partial thromboplastin time, prothrombin time, thrombin time, fibrinogen [FIB], platelet count, and D-dimer) in flap compromise are limited. The aim of the present study was to compare coagulation parameter variables in patients with and without flap compromise. MATERIALS AND METHODS In this retrospective cohort study, patients were recruited from the Department of Oral and Maxillofacial Surgery at the Second Xiangya Hospital (Changsha, Hunan, China) from July 2016 through July 2017. The primary predictor variable was a set of coagulation parameters. The primary outcome variable was flap compromise. The other variables were age, gender, tumor stage, smoking, and prior radiotherapy. Descriptive, bivariate, receiver operating characteristic (ROC) curves and regression statistics were computed. Statistical significance was set at less than .05 with 95% reliability. RESULTS A total of 503 patients with 42 compromised flaps were identified in this study. Venous thrombosis, arterial thrombosis, or no confirmed reason for compromise was observed in 28, 5, or 9 compromised flaps, respectively. Only FIB was associated with flap compromise or venous thrombosis at adjusted analyses, although the predictive values were low at ROC analysis. For patients with D-dimer lower than 0.4 μg/mL, the likelihood of venous thrombosis was greater than that for patients with D-dimer of at least 0.4 μg/mL (P = .0414). For patients with FIB lower than 3.5 g/L, the likelihood of venous thrombosis was greater than that for patients with FIB of at least 3.5 g/L (P = .0336). CONCLUSION Decreased FIB was associated with a higher rate of flap compromise. In patients with D-dimer lower than 0.4 μg/mL or FIB lower than 3.5 g/L, the risk of venous thrombosis was higher.
