Peribiliary Gland Hyperplasia That Required Differentiation from Extrahepatic Bile Duct Cancer: A Case Report.

Introduction: The peribiliary gland is an accessory bile duct gland. Hyperplasia of these tissues may lead to elevation of the mucosa in the bile ducts and bile duct stenosis. We herein report a case of peribiliary gland hyperplasia that required preoperative differentiation from bile duct cancer, with a discussion of the literature. Case Presentation: The patient had an adenomatous lesion in the ascending colon that was difficult to treat endoscopically; therefore, surgery was planned. Preoperative abdominal ultrasonography revealed a bile duct tumor, and endoscopic ultrasonography revealed a mass lesion around the confluence of the cystic duct. Computed tomography revealed localized wall thickening in the middle bile duct, and the upstream bile ducts were slightly dilated. In addition, continuous thickening of the bile duct wall from the gallbladder to the confluence of the cystic duct was observed. No distant metastases, such as liver metastases, or nearby enlarged lymph nodes were observed. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed a papillary-like elevated lesion in the bile duct near the confluence of the cystic duct, and a biopsy and bile cytology from the same area showed no malignant findings. As a result, the possibility that the patient had gallbladder or bile duct cancer could not be ruled out; therefore, a policy of surgery together with the ascending colon tumor was decided after receiving sufficient informed consent. During surgery, the patient underwent extrahepatic bile duct resection, reconstruction of the biliary tract using the Roux-en-Y method, and right hemicolectomy. Both duodenal and hilar bile duct transects were subjected to a fast frozen section analysis during surgery, and the results were negative for cancer. A histopathological examination of the resected specimen revealed no malignant findings in the bile duct lesions, and a diagnosis of peribiliary gland hyperplasia with chronic inflammatory cell infiltration and fibrosis of the extrahepatic bile duct wall was made. Conclusions: We encountered a case of peribiliary gland hyperplasia that was difficult to distinguish from bile duct cancer.

[Cardiac Tamponade After Left Upper Lobectomy:Report of Two Cases].

We report two rare cases of cardiac tamponade after left upper lobectomy. Case 1:A 76-year-old man underwent thoracoscopic left upper lobectomy and lymph node dissection for lung cancer. The patient suddenly developed cardiac tamponade the day after surgery. Emergency surgery was performed to stop bleeding and confirm the source of bleeding, and dark red pericardial fluid and hematoma were observed in the pericardial sac. There was no postoperative recurrence of cardiac tamponade. He died 1 year and 2 months after the operation. Case 2:A 77-year-old woman underwent thoracoscopic left upper lobectomy and lymph node dissection for lung cancer. The patient did well until the 6th postoperative day. On the 7th postoperative day, she complained of sudden severe back pain, immediately after which she lost consciousness and went into cardiopulmonary arrest. The echocardiography revealed cardiac tamponade, and emergency pericardiocentesis was performed. The patient died without circulatory improvement despite drainage of approximately 200 ml of bloody pericardial fluid. The pathological findings of autopsy revealed penetrating atherosclerotic ulcer at the descending aorta. We speculated that severe back pain caused the afterload of left ventricle and the increase in left atrial pressure through mitral regurgitation, which might result in a bleeding from the staple-line of superior pulmonary vein in the pericardium.

Neutral selection and clonal expansion during the development of colon cancer metastasis.

Intratumor heterogeneity has been shown to play a role in the malignant progression of cancer. Although clonal evolution in primary cancer has been well studied, that in metastatic tumorigenesis is not fully understood. In this study, we established human colon cancer-derived organoids and investigated clonal dynamics during liver metastasis development by tracking barcode-labelled subclones. Long-term subclone co-cultures showed clonal drift, with a single subclone becoming dominant in the cell population. Interestingly, the selected subclones were not always the same, suggesting that clonal selection was not based on cell intrinsic properties. Furthermore, liver tumors developed by co-transplantation of organoid subclones into the immunodeficient mouse spleen showed a progressive drastic reduction in clonal diversity, and only one or two subclones predominated in the majority of large metastatic tumors. Importantly, selections were not limited to particular subclones but appeared to be random. A trend towards a reduction in clonal diversity was also found in liver metastases of multiple color-labeled organoids of mouse intestinal tumors. Based on these results, we propose a novel mechanism of metastasis development, i.e. a subclone population of the disseminated tumor cells in the liver is selected by neutral selection during colonization and constitutes large metastatic tumors.

Decreased oral function in Japanese inpatients with schizophrenia.

AIM: Oral function in patients with schizophrenia has not been well-characterized. To address this, we performed a cross-sectional study of oral function in Japanese inpatients with schizophrenia. METHODS: We measured oral function, including occlusal force, tongue-lip motor function, tongue pressure, and masticatory function in 130 Japanese inpatients with schizophrenia. We then compared the frequency of clinical signs of oral hypofunction among 63 non-elderly and 67 elderly inpatients with schizophrenia, as well as data from 98 elderly control participants from a previous Japanese study. RESULTS: The frequency of reduced occlusal force was significantly higher in the elderly inpatients (76.2%) than in the non-elderly inpatients (43.9%) and elderly controls (43.9%). The frequency of decreased tongue-lip motor function in non-elderly inpatients (96.8%) and elderly inpatients (97.0%) was significantly higher than that in elderly controls (56.1%). The frequency of decreased tongue pressure in non-elderly inpatients (66.1%) and elderly inpatients (80.7%) was significantly higher than that in elderly controls (43.9%). Finally, the frequency of decreased masticatory function was highest in elderly inpatients (76.5%), followed by non-elderly inpatients (54.8%) and elderly controls (15.3%). CONCLUSION: Oral function was decreased in both non-elderly and elderly Japanese inpatients with schizophrenia compared with elderly controls.

Basal differentiation and expression status of SOX2 and KLF4 in basal layers are prognostic factors for disease-specific survival in oral squamous cell carcinoma.

BACKGROUND: Basal differentiation in oral squamous cell carcinoma is usually detected at invasive sites. However, its significance as a prognostic value has been poorly investigated. METHODS: COL17 was selected as a basal differentiation marker because of its stable expression in the basal-like cells of oral squamous cell carcinoma. Sixty-five cases of oral squamous cell carcinoma were subclassified into COL17-high (30 cases) and -low (35 cases) types, and the prognostic value was analyzed by Cox regression analysis. In addition, the stem cell markers such as SOX2, KLF4, MYC as well as the stem cell-related markers BMI1, EZH2, and YAP and its paralog TAZ, were immunohistochemically analyzed. Their prognostic values were investigated along with their COL17 status by Cox regression analysis. RESULTS: No significant difference was observed between the COL17-high and -low groups in the disease-specific survival and recurrence-free survival in oral squamous cell carcinoma. When the COL17-high and -low categories were combined with the SOX2, KLF4, EZH2, or YAP/TAZ status in the basal layers, together with gender and age as covariates, the hazard ratios reached 3.3, 3.7, 2.8, and 3.1, respectively. In addition, multivariate analysis, including COL17, SOX2, and KLF4, with gender and age as covariates, showed a significantly poor prognosis for disease-specific survival. CONCLUSION: Based on the relatively high hazard ratios, it is indicated that basal differentiation and the expression status of SOX2 and KLF4 in the basal layers are prognostic factors for oral squamous cell carcinoma.

Masseter and digastric muscle activity evaluation using a novel electromyogram that utilizes elastic sheet electrodes.

PURPOSE: To evaluate the reproducibility and reliability of a novel electromyogram (EMG) device with a flexible sheet sensor for measuring muscle activity related to mastication and swallowing. METHODS: We developed a new EMG device made of elastic sheet electrodes to measure the masseter and digastric muscle activities for evaluating mastication and swallowing. To examine the measurement reproducibility of the new EMG device, masseter muscle activity was analyzed using the intraclass correlation coefficient (ICC). Further, we measured the maximum amplitude, duration, integrated value, and signal-to-noise ratio (SNR) using the new EMG device and conventional EMG devices and evaluated the reliability using ICC and Bland-Altman analysis. RESULTS: We confirmed high ICC (1,1) and ICC (2,1) scores (0.92 and 0.88, respectively) while measuring the reproducibility of the new EMG device. When compared to the active electrode EMG device, we found a high correlation for the maximum amplitude (0.90), duration (0.99), integrated values (0.90), and SNR (0.75), with no observation of significant fixed errors. Moreover, the regression coefficient was not significant for any of the evaluation items and no proportional error was observed. Compared with the passive electrode EMG device, the maximum amplitude and duration were highly correlated (0.73 and 0.89). In addition, the SNR exhibited a significant fixed error. In contrast, the regression coefficient was not significant for any of the evaluation items and no proportional error was observed. CONCLUSIONS: Our results suggest that the new EMG device can be used to reliably and reproducibly evaluate muscle activity during mastication and swallowing.

Expression of Periostin in Benign Salivary Gland Tumors.

Parotid tumors present a wide range of histological features, from benign to malignant. Periostin, an extracellular matrix protein specifically expressed in the periosteum and periodontal ligament, is isolated from osteoblast cell lines. It regulates fibrosis and collagen deposition and plays an important role in myocardial repair after myocardial infarction. It is also known to be involved in otorhinolaryngological-diseases. This study included 36 patients [38 specimens; 16 men and 20 women, mean age 59.2 (range 26-82) years] who underwent parotid tumor resection at the Division of Otorhinolaryngology, Tohoku Medical and Pharmaceutical University, between April 2017 and March 2022 and were clinically and pathologically diagnosed as having benign parotid tumors. Formalin-fixed, paraffin-embedded sections from the surgical specimens were autoclaved and immunostained with anti-periostin antibodies to evaluate the expression and distribution of periostin. Histologically, the tumors were diagnosed as pleomorphic adenomas in 15 cases (15 specimens), Warthin's tumors in 13 cases (15 specimens), basal cell adenomas in 2 cases (2 specimens), oncocytomas in 4 cases (4 specimens), and myoepitheliomas in 2 cases (2 specimens). An increased expression of periostin was found in 32 of 38 samples (84.2%) in the stroma of benign parotid tumors. Four distinct patterns of periostin expression were observed in benign parotid gland tumors: negative, superficial, infiltrative, and diffuse. Statistically significant differences were found between periostin expression patterns and histological classification of the tumors. Our results suggest that periostin may be involved in the pathogenesis of benign parotid tumors and could serve as a new biomarker for these tumors.

Relationship between maximal isometric tongue pressure and limit of fracture force of gels in tongue squeezing.

BACKGROUND: There is no clear objective indicator for selecting soft foods that are required for food bolus formation in older people with impaired oral function. OBJECTIVE: This study aimed to investigate the relationship between maximal isometric tongue pressure (MITP) and the mechanical properties of gels that can be crushed by the tongue. METHODS: This study included 65 healthy participants aged 22-96 (young group; 15 males, 15 females; older dentate group; 7 males, 8 females; older edentulous group; 10 males, 10 females). MITP was measured by the balloon-probe device. Agar gel with 10 different kinds of fracture force from 10N to 100N was used. The limit of fracture force of gels (LFFG) that were crushed by the tongue was measured by the up-and-down method. In the older edentulous group, two items were measured with and without dentures. Spearman's rank correlation coefficient was used to evaluate the relationship between MITP and LFFG in each group (p < .05). RESULTS: There were positive correlations between MITP and LFFG in all groups (overall groups: rs = .66, young group: rs = .46, older dentate group: rs = .61, older edentulous group with dentures: rs = .60, older edentulous group without dentures: rs = .47). CONCLUSION: MITP and LFFG were positively correlated in young, older dentate and older edentulous groups, suggesting that MITP has the potential to be an objective indicator of the range of mechanical properties of soft food that can be crushed by the tongue.

Detection Rates of Non-Cavitary Epithelioid Cell Granuloma by Gastrointestinal Biopsy in Patients with Treatment-Naïve Crohn's Disease.

Introduction: Detecting non-cavitary epithelioid cell granuloma by gastrointestinal biopsy is important in the initial diagnosis of Crohn's disease (CD). In the present study, we aimed to determine the rate of granuloma detection by gastrointestinal biopsy according to the number of biopsies performed. Methods: The present study included patients newly diagnosed with CD at our hospital between April 2017 and March 2023. During endoscopic examinations, biopsy specimens were taken from affected lesions. Initially, one section per biopsy was examined to detect granuloma. In cases where no granulomas were detected, step sections were additionally prepared and examined. The rate of granuloma detection by gastrointestinal biopsy was retrospectively examined. Results: A total of 30 patients with a new diagnosis of CD were included in this study. In total, 284 gastrointestinal biopsies were performed in 29 cases. The rate of granuloma detection by gastrointestinal biopsy per case was 58.6% (17 out of 29 cases). The rate of granuloma detection by gastrointestinal biopsy per biopsy was 6.0% (17 out of 284 biopsies) on initial histological examination and 11.6% (33 out of 284 biopsies) following examination of step sections. The rate of granuloma detection was significantly improved by performing histological examination of step sections compared with initial examinations (p < 0.05). Conclusion: The rate of granuloma detection per biopsy was 11.6%, even after histological examination of step sections. These results indicate that performing multiple intestinal biopsies and assessing for the presence of granuloma using multiple section examinations are required in the initial diagnosis of CD.

Renal pelvis cancer with initial symptoms of malignant gastric outlet obstruction.

Introduction: Gastric outlet obstruction caused by upper tract urothelial carcinoma is rare. Case presentation: A 78-year-old man presented to the hospital with nausea and vomiting. No hematuria was observed. Computed tomography revealed a tumor in the right renal pelvis and duodenal stenosis. Gastrojejunostomy was performed to treat the symptoms of the gastric outlet obstruction so that the patient could resume oral intake and outpatient chemotherapy. Chemotherapy was unsuccessful, and the patient died 9 months after the gastrojejunostomy. Histological assessment of an autopsy specimen revealed plasmacytoid urothelial carcinoma with direct infiltration of the duodenal wall, which caused the stenosis. Conclusion: Autopsy revealed a right renal pelvis cancer causing gastric outlet obstruction. Early gastrojejunostomy enabled oral intake and outpatient visits.

A Case of Primary Angiitis of the Central Nervous System with Pathological Findings of Eosinophilic Granulomatosis with Polyangiitis.

A 79-year-old woman presented with difficulty walking and disturbance of consciousness. Magnetic resonance imaging revealed diffuse white matter lesions and abnormal signals along the surface of the brain and sulci. A brain biopsy revealed granulomatous vasculitis with eosinophil infiltration. There was no peripheral blood eosinophilia or evidence of angiitis in other organs, and primary angiitis of the central nervous system (PACNS) with pathological findings of eosinophilic granulomatosis with polyangiitis (EGPA) was diagnosed. Steroids and other immunosuppressant therapies showed only limited effects. PACNS with pathological findings of EGPA is extremely rare, and a prompt brain biopsy is necessary for a diagnosis.

Pericyte detachment and renal congestion involve interstitial injury and fibrosis in Dahl salt-sensitive rats and humans with heart failure.

Congestive heart failure produces fluid volume overload, central and renal venous pressure elevation, and consequently renal congestion, which results in worsening renal function. Pericyte detachment and pericyte-myofibroblast transition (PMT) were linked to renal interstitial fibrosis. Dahl salt-sensitive hypertensive (DahlS) rats are a non-surgical renal congestion model. The relation, however, between renal interstitial damage, pericyte morphology, and PMT in the renal congestion of DahlS rats has not been reported. DahlS rats (8-week-old) were fed normal salt (NS, 0.4% NaCl) or high salt (HS, 4% NaCl), and the left kidney was decapsulated to reduce renal interstitial hydrostatic pressure (RIHP) at 9 weeks old. One week after capsulotomy, both kidneys were analyzed by molecular and histological techniques. Renal pericyte structure was assessed in the body donors with/without venous stasis. Markers of tubulointerstitial damage, interstitial fibrosis, and PMT were upregulated in the right non-decapsulated kidney of DahlS rats fed HS. Renal tubular injury and fibrosis were detected in the HS diet groups in histological analysis. Pericyte detachment was observed in the right non-decapsulated kidney of DahlS rats fed HS by low vacuum-scanning electron microscopy. Decapsulation in DahlS rats fed HS attenuated these findings. Also, renal pericytes detached from the vascular wall in patients with heart failure. These results suggest that pericyte detachment and PMT induced by increased RIHP are responsible for tubulointerstitial injury and fibrosis in DahlS rats and humans with renal congestion. Renal venous congestion and subsequent physiological changes could be therapeutic targets for renal damage in cardiorenal syndrome.

Immunohistochemical localization of CD31, CD34, and periostin in vocal fold polyps.

BACKGROUND: Long-term voice-abuse or sudden vocal fold microvascular disruption can lead to injury and subsequent repair/remodeling of the vocal fold mucosa. Periostin is known to be involved in airway remodeling and in various otolaryngological diseases. In ischemic heart disease, increased CD31 expression has been observed around cardiomyocytes during remodeling, and endothelial proliferation has been reported to occur at these sites. OBJECTIVES: We investigated the expression and the roles of CD31, CD34, and periostin in the formation of vocal fold polyps. MATERIALS AND METHODS: Fifty-seven samples of vocal fold polyps were investigate histopathologically and immunohistochemically. RESULT: Expression of CD31 and CD34 was detected in 41 (71.9%) and 53 (93.0%) samples, respectively, obtained from patients with vocal fold polyp. Expression of periostin was detected in 41 (71.9%) samples obtained from patients with vocal polyps. The vocal polyp samples could be classified into three histological subtypes. Three patterns of CD31 and CD34 expression were observed in the vocal polyp. Four patterns of periostin expression were observed in vocal polyps. An association was observed between the CD31 expression pattern and the histological subtype of vocal fold polyps. CONCLUSION AND SIGNIFICANCE: In vocal fold polyps, evaluation of vascular endothelial markers may be useful for staging.

Isolated metastases to the common iliac and mesorectal lymph nodes suggesting an atypical metastatic route in upper rectal cancer: A case report.

INTRODUCTION: Most lymphatic vessels in the upper rectum run parallel to the superior rectal artery and up to the inferior mesenteric artery. Here, we report a rare case of upper rectal cancer with atypical lymphatic spread. PRESENTATION OF CASE: A 39-year-old woman was diagnosed with upper rectal cancer and isolated lymph node (LN) metastases to the mesorectal and right common iliac LNs. The patient underwent laparoscopic low anterior resection with targeted dissection of the right common iliac LNs. The pathological diagnosis was T3N2M0, and the patient received postoperative adjuvant chemotherapy. One year later, local recurrence was found at the sacral promontory level, where the targeted lymphadenectomy had been performed previously. The recurrent tumor was surgically resected together with the attached presacral fascia. The patient subsequently received postoperative adjuvant chemotherapy, and there was no recurrence one year after the last surgery. DISCUSSION: Isolated metastases were observed in the right common iliac and mesorectal LNs. The locally recurrent tumor included lymphatic vessels running along the median sacral artery. No metastatic tumor was found in the internal iliac area at the time of the initial diagnosis nor during recurrence. Thus, this case suggests the presence of a rare metastatic route from the mesorectal LN to the common iliac LN via the median sacral lymphatics. CONCLUSION: Lymphatic spread of rectal cancer may be predictable; however, rare patterns of LN metastasis can exist. The assessment of lymphatic flow is crucial for improving the oncological outcomes of rectal cancer surgery.

Diffuse pancreatic parenchymal atrophy, an imaging finding predictive of the development of pancreatic ductal adenocarcinoma: A case-control study.

Background and Aim: Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer, partly because its early detection is difficult. This study aimed to identify computed tomography (CT) findings associated with PDAC prior to diagnosis. Methods: Past CT images were retrospectively collected from the PDAC group (n = 54) and the control group (n = 90). The following imaging findings were compared: pancreatic mass, main pancreatic duct (MPD) dilatation with or without cutoff, cyst, chronic pancreatitis with calcification, partial parenchymal atrophy (PPA), and diffuse parenchymal atrophy (DPA). In the PDAC group, CT findings were examined during the pre-diagnostic period and 6-36 months and 36-60 months before diagnosis. Multivariate analyses were performed using logistic regression. Results: MPD dilatation with cutoff (P < 0.0001) and PPA (P = 0.023) were identified as significant imaging findings 6-36 months before diagnosis. DPA was identified as a novel imaging finding at 6-36 months (P = 0.003) and 36-60 months (P = 0.009) before diagnosis. Conclusion: DPA, MPD dilatation with cutoff, and PPA were identified as imaging findings associated with pre-diagnostic PDAC.

Immunohistochemical Localization of D-ß-Aspartic Acid and Periostin in Vocal Fold Polyps.

Long-term voice abuse or sudden vocal fold microvascular disruption may lead to injury and subsequent repair/remodeling in the vocal fold mucosa. Periostin is known to be involved in airway remodeling and also in various otolaryngological diseases. D-ß-aspartic acid is the major isomer of D-aspartic acid found in elderly tissue. In this study we investigated the expression and the role of D-ß-aspartic acid and periostin in the formation of vocal fold polyps. The expression patterns of D-ß-aspartic acid and periostin in 36 surgical specimens of vocal fold polyps from 36 patients were investigated immunohistochemically. In the epithelium of vocal polyps, D-ß-aspartic acid was expressed in all cases. Expression of D-ß-aspartic acid was detected in 25 samples obtained from patients with vocal fold polyps stroma. Expression of periostin was detected in 28 samples obtained from patients with vocal fold polyps. Two patterns of D-ß-aspartic acid expression were observed in vocal fold polyps stroma: positive type and negative type. The following four patterns of periostin expression were observed in vocal fold polyps: negative type, superficial type, infiltrative type, and diffuse type. An association was observed between D-ß-aspartic acid expression patterns and periostin expression patterns. From these findings we speculate that periostin and D-ß-aspartic acid participate in certain pathological changes in vocal fold polyps, such as extracellular matrix accumulation, local fibrosis, and the formation and development of vocal fold polyps.

Masticatory Performance Test Using a Gummy Jelly for Older People with Low Masticatory Ability.

Evaluation of masticatory ability has become more important in an aging society because decreased masticatory ability has the potential to affect the general health of older people. A new masticatory performance test, intended for older people with low masticatory ability, has been developed using gummy jelly half the size of that used in the conventional masticatory performance test. This study aimed to investigate the compatibility between the new and conventional tests and the adaptation of the new test. The new test using the 8-grade visual score with half-size gummy jelly was performed among 137 removable denture wearers (mean age 75.8 ± 9.0 years) with low masticatory performance (a score of ≤4 on a conventional test). The correlation between the scores of half-size gummy jelly (VS-H) in the new test and those of full-size gummy jelly (VS) in the conventional test was evaluated. VS-H among the groups divided by VS were also compared. A strong positive correlation was detected between VS-H and VS (rs = 0.70). In groups with VS of 0 and 1, VS-H values were widely distributed from 0 to 7. There were significant differences in VS-H between the groups with VS of 0-2 but no significant differences in VS-H between the groups with VS of 2-4. Therefore, the masticatory performance test using half-size gummy jelly is suitable for a detailed evaluation of masticatory ability in older people with low masticatory ability when their visual score of full-size gummy jelly in the conventional test is 2 or less.

Changes in strain energy density in the temporomandibular joint disk after sagittal split ramus osteotomy using a computed tomography-based finite element model.

PURPOSE: We evaluated the changes in the strain energy density (SED) in the temporomandibular joint (TMJ) disk after sagittal split ramus osteotomy (SSRO) at three time points. A finite element model (FEM) based on real patient-based computed tomography (CT) data was used to examine the effect of SSRO on the TMJ. METHODS: Measurements of the condylar position and angulation in CT images and FEM analyses were performed for 17 patients scheduled to undergo SSROs at the following time points: before surgery, immediately after surgery, and 1 year after surgery. SED on the entire disk was calculated at each of the three time points using FEM. Furthermore, the relationship between individual SED values and the corresponding condylar position was also evaluated. RESULTS: No significant change was observed in the condylar position at the three time points. The FEM analysis showed that SED was the highest and lowest immediately after and 1 year after surgery, respectively. A possible SED distribution imbalance between the left and right joints was improved 1 year after SSRO. Concerning the effect of fossa morphometry and condylar position, wide and deep glenoid fossae and a more posterior condylar position tended to show lower SED. CONCLUSION: SED in the articular disk temporarily increased after surgery and significantly decreased 1 year after surgery compared with that before surgery. SSRO generally improved the imbalance between the left and right joints. Thus, SSRO, which improves maxillofacial morphology, may also improve components of temporomandibular disorders.

A facelift procedure for resection of a branchial cleft cysts.

OBJECTIVES: Branchial cleft cysts (BCCs) are common in daily practice, however, BCC patients suffer aesthetic problems due to postoperative scars on visible parts after surgery. To analyze the feasibility, surgical outcomes and possible risks and complications encountered during a facelift procedure for patients with BCC. METHODS: This retrospective analysis examined patients who had undergone surgery for branchial cleft cyst using a facelift procedure (n = 16) or conventional transcervical resection (n = 20) at our institutes between April 2015 and August 2021. RESULTS: There was no significant difference between the groups that underwent the facelift procedure or conventional transcervical resection as to the average size of the cysts, operating time, bleeding, drain out, or recurrence. None of the patients needed to switch from the facelift procedure to conventional transcervical resection. In all the patients in the facelift procedure group, postoperative scars were fully concealed by the auricle and hair. However, four patients in the facelift procedure group experienced a transient auricular complication after surgery. CONCLUSION: The facelift procedure provides adequate visualization, workspace and excellent cosmetic results in suitably selected cases with BCC.
