Background: Anastomotic leakage (AL) following esophagectomy represents a serious complication that often results in prolonged hospitalization and necessitates repeated interventions, including nothing-by-mouth (NPO) restriction, endoscopic vacuum therapy (EVT), or surgical repair. In this study, we evaluated the patterns and outcomes of AL treatment. Methods: We retrospectively reviewed the medical records of patients who underwent esophagectomy for esophageal cancer at a single center between 2003 and 2020. Of 3,096 examined cases, 181 patients (5.8%) with AL were included in the study: 114 patients (63%) with cervical anastomosis (CA) and 67 (37%) with intrathoracic anastomosis (TA). Results: The incidence of AL was 11.9% in the CA and 3.2% in the TA group (p<0.001). Among patients with CA who developed AL, 87 (76.3%) were managed with NPO, 15 (13.2%) with EVT, and 12 (10.5%) with surgical repair. Over 90% of patients with cervical AL resumed an oral diet by the time of discharge, regardless of treatment method. Among patients with TA and AL, 36 (53.7%) received NPO, 25 (37.7%) underwent EVT, and 6 (9%) required surgery. Of these, 34 patients who were managed with NPO and 19 with EVT could resume an oral diet. However, only 2 patients who underwent surgery resumed an oral diet, and 2 patients required additional EVT. Conclusion: Although patients with CA displayed a higher incidence of AL, their rate of successful oral intake exceeded that of those with TA, regardless of treatment method. Among patients exhibiting AL with TA, EVT was more commonly employed than in CA cases, and it appears effective.

Objectives: This prospective observational study aimed to assess the clinical outcomes of perioperative airway and ventilatory management in patients undergoing surgery for oral cavity cancer. The study described the frequencies and types of procedures for securing the airway and the duration and types of postoperative ventilatory support. We compared the findings with those of the TRACHY study. Patients and Methods: One hundred patients undergoing oral cavity oncological surgeries were included. Airway assessment included inter-incisor gap, Mallampati class, neck movements, and radiological features. Surgical parameters, postoperative ventilatory support, and complications were documented. Results: The buccal mucosa was the most common cancer site (48.0%), and direct laryngoscopy was deemed difficult in 58.0% of patients. Awake fibreoptic intubation or elective tracheostomy was required in 43.0% of cases. Thirty-three patients were extubated on the table, and 34 patients were successfully managed with a delayed extubation strategy. In comparison with the TRACHY study, variations were observed in demographic parameters, tumour characteristics, and surgical interventions. Our mean TRACHY score was 1.38, and only five patients had a score ≥4. Prophylactic tracheostomy was performed in 2.0% of cases, in contrast to the TRACHY study in which 42.0% of patients underwent the procedure. Conclusion: The study emphasizes the challenges in airway management for oral cavity cancer surgery. While prophylactic tracheostomy may be necessary in specific cases, individualized approaches, including delayed extubation, are preferrable to maximize safety. Our findings contribute to better understanding and managing perioperative challenges in oral cancer patients and highlight the need for personalized strategies. Scoring systems like TRACHY should not be accepted as universally applicable.

Background Reconstruction of oropharyngeal defects after resection of oropharyngeal cancer is a significant challenge. The purpose of this study is to introduce reconstruction using a combination of a buccinator myomucosal flap and a buccal fat pad flap after cancer excision and to discuss the associated anatomy, surgical procedure, and clinical applications. Methods In our study, a combination of a buccinator myomucosal flap with a buccal fat pad flap was utilized for reconstruction after resection of oropharyngeal cancer, performed between 2013 and 2015. After oropharyngectomy, the defect with exposed vital structures was noted. A buccinator myomucosal flap was designed and elevated after an assessment of the flap pedicle. Without requiring an additional procedure, a buccal fat pad flap was easily harvested in the same field and gently pulled to obtain sufficient volume. The flaps were rotated and covered the defect. In addition, using cadaver dissections, we investigated the feasibility of transposing the flaps into the lateral oropharyngeal defect. Results The reconstruction was performed in patients with squamous cell carcinoma. The largest tumor size was $5cm{\times}2cm(length{\times}width)$. All donor sites were closed primarily. The flaps were completely epithelialized after four weeks, and the patients were followed up for at least six months. There were no flap failures or postoperative wound complications. All patients were without dietary restrictions, and no patient had problems related to mouth opening, swallowing, or speech. Conclusions A buccinator myomucosal flap with a buccal fat pad flap is a reliable and valuable option in the reconstruction of oropharyngeal defects after cancer resection for maintaining functionality.

Purpose: The result of all malignant neoplasms including oral cancer is decided by long-term prognosis. However, until now, there are only a few reports about long-term prognosis of cancer secluded in the oral cavity. So, we investigated all patients that visited our clinic for oral squamous cell carcinoma (SCCa) for the last 10 years. From this survey, we hope to find important factors that influence prognosis of the disease. Patients and Methods: A retrospective study was performed for patients that visited the oral oncology clinic for oral cancers from Jan. 2001 to Feb. 2010. We selected the patients that were diagnosed with SCCa and received curative treatment. In these patients, we investigated basic epidemiology, smoking history, body mass index, recurrence rate, treatment methods, pathologic data and 5-yr survival rate. Results: There was a total of 185 patients (115 males, 70 females and mean age: 57.3 years) that visited the oral oncology clinic for oral SCCa. Areas of primary lesion were tongue (105 cases, 57%), lower gum (19 cases, 10%), floor of mouth (16 caess, 8%), retromolar trigone (12 cases, 6.5%), and buccal cheek (11 cases, 6%). Other involved areas were upper gum, palate, lip, and salivary glands-of 1 case each. The overall 5-year survival rate was 63.7%. The factors that influenced prognosis of the disease were stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. Conclusion: The factors that influence prognosis of disease are stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. To point out a current trend, the mean age of patients that developed oral cancer was lower than that of before. Secondly, the prevalence of oral cancer in non-smoker are on the rise. Thus, further studies on etiology and epidemiology should be done.

Background: Reconstructive surgery is often required for tumors of the oral and maxillofacial region, irrespective of whether they are benign or malignant, the area involved, and the tumor size. Recently, three-dimensional (3D) models are increasingly used in reconstructive surgery. However, these models have rarely been adapted for the fabrication of custom-made reconstruction materials. In this report, we present a case of maxillary reconstruction using a laboratory-engineered, custom-made mesh plate from a 3D model. Case presentation: The patient was a 56-year-old female, who had undergone maxillary resection in 2011 for intraoral squamous cell carcinoma that presented as a swelling of the anterior maxillary gingiva. Five years later, there was no recurrence of the malignant tumor and a maxillary reconstruction was planned. Computed tomography (CT) revealed a large bony defect in the dental-alveolar area of the anterior maxilla. Using the CT data, a 3D model of the maxilla was prepared, and the site of reconstruction determined. A custom-made mesh plate was fabricated using the 3D model (Okada Medical Supply, Tokyo, Japan). We performed the reconstruction using the custom-made titanium mesh plate and the particulate cancellous bone and marrow graft from her iliac bone. We employed the tunneling flap technique without alveolar crest incision, to prevent surgical wound dehiscence, mesh exposure, and alveolar bone loss. Ten months later, three dental implants were inserted in the graft. Before the final crown setting, we performed a gingivoplasty with palate mucosal graft. The patient has expressed total satisfaction with both the functional and esthetic outcomes of the procedure. Conclusion: We have successfully performed a maxillary and dental reconstruction using a custom-made, pre-bent titanium mesh plate.

Objectives: Fluorine-18 fluorodeoxyglucose positron emission tomography ($^{18}F$-FDG PET) is a non-invasive diagnostic tool for many human cancers wherein glucose uptake transporter-1 (GLUT-1) acts as a main transporter in the uptake of $^{18}F$-FDG in cancer cells. Increased expression of glucose transporter-1 has been reported in many human cancers. In this study, we investigated the correlation between $^{18}F$-FDG accumulation and expression of GLUT-1 in oral cancer. Materials and Methods: We evaluated 42 patients diagnosed with oral squamous cell carcinoma (OSCC) and malignant salivary gland tumor as confirmed by histology. 42 patients underwent pre-operative $^{18}F$-FDG PET, with the maximum standardized uptake value ($SUV_{max}$) measured in each case. Immunohistochemical staining was done for each histological specimen, and results were evaluated post-operatively according to the percentage (%) of positive area, intensity, and staining score. Results: For OSCC, $SUV_{max}$ significantly increased as T stage of tumor classification increased. For malignant salivary gland tumor, $SUV_{max}$ significantly increased as T stage of tumor classification increased. For OSCC, GLUT-1 was expressed in all 36 cases. GLUT-1 staining score (GSS) increased as T stage of tumor classification increased, with the difference statistically significant. For malignant salivary gland tumor, GLUT-1 expression was observed in all 6 cases; average GSS was significantly higher in patients with cervical lymph node metastasis than that in patients without cervical lymph node metastasis. Average GSS was higher in OSCC ($11.11{\pm}1.75$) than in malignant salivary gland tumor ($5.33{\pm}3.50$). No statistically significant correlation between GSS and $SUV_{max}$ was observed in OSCC or in malignant salivary gland tumor. Conclusion: We found no statistically significant correlation between GSS and $SUV_{max}$ in OSCC or in malignant salivary gland tumor. Studies on the various uses of GLUT during $^{18}F$-FDG uptake and SUV and GLUT as tumor prognosis factor need to be conducted through further investigation with large samples.

Background and Objectives: Surgical ablation of tumors in the oral cavity and the oropharynx results in a three dimensional defect because of the needs to resect the adjacent area for the surgical margin. Although a variety of techniques are available, radial forearm free flap has been known as an effective method for this defect, which offers a thin, pliable, and relatively hairless skin and a long vascular pedicle. We report the clinical results of our 54 consecutive radial forearm free flaps used for oral cavity and oropharynx cancers. Materials and Methods: We reviewed the medical records of patients who were offered intraoral reconstruction with a radial forearm free flap after ablative surgery for oral cavity and oropharyngeal cancers from August 1994 to February 2003 and analyzed surgical methods, flap survival rate, complication, and functional results. Among these, 20 cases were examined with modified barium swallow to evaluate postoperative swallowing function and other 8 cases with articulation and resonance test for speech. We examined recovery of sensation with two-point discrimination test in 15 cases who were offered sensate flaps. Results: The primary sites were as follows : mobile tongue (18), tonsil (17), floor of mouth (4), base of tongue (2), soft palate (2), retromolar trigone (3), buccal mucosa (1), oro-hypopharynx (6), and lower lip (1). The paddles of flaps were tailored in multilobed designs from oval shape to tetralobed design and in variable size according to the defects after ablation. This procedures resulted in satisfactory flap success rate (96.3%) and showed good swallowing function and social speech. Eight of 15 cases (53.3%) who had offered sensate flap showed recovery of sensation between 1 and 6 postoperative months (average 2.6 month). Conclusion: The reconstruction with radial forearm free flap might be an excellent method for the maximal functional results after ablative surgery of oral cavity and oropharyngeal cancers that results in multidimensional defect.
