    Abstract Epithelial-myoepithelial carcinoma (EMC) of the parotid gland is a comparatively rare tumor that accounts for less than 1% of all salivary gland tumors. A patient with EMC of the parotid gland that was initially diagnosed as pleomorphic adenoma and that recurred locally during the watchful waiting period but was controlled by surgery under local anesthesia is reported. An 80-year-old man had noticed a swelling in the left infra aural region. A left parotid gland tumor was suspected, and he was referred to our department. Magnetic resonance imaging (MRI) and fine-needle aspiration cytology findings were suggestive of pleomorphic adenoma of the superficial lobe of the parotid gland, and this was therefore resected under general anesthesia. Postoperative histopathological examination, immunostaining, and genetic tests resulted in a diagnosis of EMC. Postoperative pathological review showed that part of the resection margin was positive. The possibility of recurrence was explained to the patient, and additional treatment was recommended, but since the patient did not desire this, a policy of watchful waiting was adopted. Signs of cutaneous metastasis in the left infra aural region were detected at 13 months postoperatively, and this metastasis was excised under local anesthesia. The resection margin was negative, and the patient's course remains uneventful. EMC is classified as a low-grade malignant tumor, but it requires stringent monitoring because of its frequent local recurrence. Since local control can usually be achieved by surgical treatment alone, and postoperative adjuvant therapy may not necessarily warranted.

    Abstract When a tracheostoma is no longer needed, the opening normally closes spontaneously after cannula removal, but some cases require tracheostoma closure. This procedure has been well described, but must be performed in such a way as to minimize its invasiveness and complications while securing a high closure rate. Our procedure for conducting tracheostoma closure technique involves the creation of two hinge flaps and one cover flap to close the tracheostomy opening. We reviewed the medical records of 23 patients (12 men, 11 women; mean age 60.0 SD19.7 years) who underwent tracheostoma closure technique between 2001 and 2019. Surgery was indicated for patients in whom closure had not occurred after conservative monitoring for ≥ 2 months following cannula removal. The surgical procedure began by raising two hinge flaps on either side of the tracheostomy opening, turning the skin surface to the luminal side to form the anterior tracheal wall. Rather than a single layer of skin, multiple skin layers were sutured together to prevent air leakage from between hinge flaps. A further cover flap was produced to cover the anterior tracheal wall, closing the tracheostomy opening. Postoperatively, the tracheal lumen was observed via fiberscopy. No stenosis of the tracheal lumen occurred in any patients, and the tracheocutaneous fistula was successfully closed in all cases. Tracheostoma closure technique using hinge flaps to reconstruct the anterior tracheal wall and a cover flap as a skin flap to cover the skin defect appears useful for patients with failure of spontaneous tracheocutaneous fistula closure.

    Abstract Objective: Narrow-band imaging (NBI) is considered useful for detecting respiratory papillomatosis. However, the choice between preoperative and intraoperative NBI depends on the facility. We investigated the usefulness of NBI and determined whether preoperative NBI can replace intraoperative NBI with a comparable detection rate.
    Methods: In this retrospective cohort study conducted at single a tertiary care center, patients with respiratory papillomatosis treated between 2017 and 2022 were enrolled. We systematically compared preoperative white light imaging (WLI) with preoperative and intraoperative NBI. The primary endpoints were the papilloma detection rate and lesion site assessed by the Derkay scoring system. The secondary endpoints were the risk factors for increased Derkay scores.
    Results: The study included 127 patients with papilloma. Intraoperative NBI yielded significantly higher Derkay scores than preoperative WLI (p < 0.001) and preoperative NBI (p = 0.004). The papilloma detection rates of preoperative WLI and preoperative NBI were not significantly different. Intraoperative NBI detected more lesions than preoperative NBI in 37 of 127 (29%) patients; the overall number of additional lesions was 47 of 279 (17%). Compared with preoperative NBI, intraoperative NBI yielded significantly higher scores for the vocal cords (p = 0.005), false vocal cords (p = 0.010), and ventricle of the larynx (p < 0.001). Elevated Derkay scores were significantly associated with male sex (p = 0.012) and alcohol consumption (p = 0.007).
    Conclusion: Intraoperative NBI is more accurate in detecting papillomatous lesions, and preoperative NBI cannot replace intraoperative NBI.

    Abstract Schwannomas are benign soft tissue tumors derived from the Schwann cells of the peripheral nerves. An intramuscular schwannoma arising within the trapezius muscle in the posterior neck is rare. We report a case of a 31-year-old woman with an intramuscular schwannoma in the trapezius muscle. A painless and smooth-surfaced mass from 10 years ago was evident on palpation in the right posterior neck. Ultrasonography revealed an oval mass with clear borders and slight internal blood flow. No continuous hypoechoic lesions were noted at the tip of the mass. Magnetic resonance imaging of the neck revealed a mass in the right posterior cervical trapezius muscle with isointensity on T1-weighted imaging and heterointensity on T2-weighted imaging. Based on these findings, a schwannoma was suspected. Ultrasonography guided fine needle aspiration cytology revealed no significant findings. During surgery, a white-colored, encapsulated-tumor mass was found in the trapezius muscle. Histopathologically, hypocellular and hypercellular areas of fusiform cells were conspicuous, and nuclear palisading was observed in a part of the hypercellular region, confirming the diagnosis of schwannoma. To our knowledge, this is an extremely rare report of an intramuscular schwannoma within the trapezius muscle; herein, we report its clinical, radiological, and pathological features.

    Abstract Background: Tibial footprint of anterior cruciate ligament (ACL) is situated close to the anterior lateral meniscal root (ALMR) attachment.
    Purpose: To investigate the impact of the size and location of the tibial tunnel for ACL reconstruction on the ACL footprint coverage and overlap to the ALMR.
    Study design: Controlled laboratory study.
    Methods: Twenty knee MRI scans from twenty healthy subjects were recruited, and three-dimensional (3D) tibia models were created to show the tibial attachment sites of ACL and ALMR. Surgical simulation of the tibial tunnel drilling was performed on each 3D model, entering the joint at an angle set at 60 degrees from the tibial plateau plane and 55 degrees from the posterior tibial condylar axis, with analysis for six different drill sizes; 7.5, 8, 8.5, 9, 9.5 and 10 mm; and nine locations; the center of the ACL attachment and eight locations 2% of the tibial width apart surrounding it. The width of the tibial plateau, the distance between ACL and ALMR attachment centers, and the size and location of the potential tibial tunnel were evaluated to determine association with the area of the ACL footprint coverage and ALMR overlap using a linear mixed effects model.
    Results: A large tunnel (p <.001), a central and anterior location (p <.029), and small tibial width (p =.015) were all associated with larger coverage of the ACL footprint. A large tunnel (p <.001), posteriorly and laterally located (p ≤ 0.001), and a small distance between the ACL and ALMR centers (p =.001) were significantly associated with a larger ALMR overlap. The association of the tunnel size to ALMR overlap reduced with a medial tunnel location.
    Conclusions: The short distance between the centers of the ALMR attachment and native ACL footprint suggests that the ALMR will always be susceptible to overlap when the tibial tunnel is drilled in ACL reconstruction. Small alterations in tunnel location can lead to a statistically significant alteration with the amount of ALMR overlap. To minimize this overlap, whilst maintaining acceptable coverage of the ACL footprint, a tibial tunnel positioned in a medial or anteromedial location from the center of the ACL footprint is recommended.

    Abstract Background: With the standardization of surgical techniques and continuous development of plate fixators, medial open-wedge high tibial osteotomy (OWHTO) has become an option for the treatment of medial knee osteoarthritis. However, it is also associated with several complications. To reduce the risk of these complications, it is essential for surgeons to accurately understand the three-dimensional (3D) anatomical structures, including the surroundings of the surgical field. Gross dissection using a cadaver provides a large surgical field and is the best learning method for studying anatomical structures in three dimensions; however, it is not available at all medical institutions.
    Methods: One female cadaveric knee, fixed using the Thiel method, was used in this study, and OWHTO was performed. A series of photographs was taken from approximately 60 different angles at each stage of the autopsy for digital photogrammetry to ensure that there was at least a 60% overlap between photographs.
    Results: Each 3D object was created to be faithful to the original specimen and displayed on an augmented reality headset. It was created to capture the subtle nuances of irregular shapes and structures, highlighting the unique ability of photogrammetry to capture pathology. This method allows surgeons to visualize the location of neurovascular injuries in the intraoperative field of view.
    Conclusions: Using a technique that applies digital photogrammetry to create 3D objects from handheld photographs, this reports for the first time an educational tool that can reproduce the anatomy related to high tibial osteotomy in three dimensions.

    Abstract Purpose: This study aimed to compare the combination of a lateral femoral cutaneous nerve (LFCN) block with a femoral nerve block (FNB) and an adductor canal block (ACB) for postoperative pain control in patients undergoing anterior cruciate ligament (ACL) reconstruction with hamstring autograft.
    Methods: A non-randomized, prospective, controlled clinical trial was conducted. The FNB and ACB groups consisted of 41 and 40 patients, respectively. Thirty minutes prior to surgery, the patients received an ultrasound-guided LFCN block either with FNB or ACB. The following values were recorded and compared between the two groups: duration of surgery, pain management during surgery (including total amount of fentanyl administered), and numerical rating scale (NRS) scores at 30 min and 4, 8, 12, 24, 48, and 72 h after surgery. Factors affecting pain relief (NRS < 2) were evaluated, including block type, total amount of fentanyl administered, duration of surgery, age, sex, body mass index, and postoperative suppository use. Significant factors predicting pain relief were determined using the Cox proportional hazard regression model.
    Results: There were no significant differences in pain management during the surgery. Pain scores were significantly lower in the ACB group at 30 min, 4 h, 24 h, and 48 h after surgery. The Cox proportional hazard regression model identified ACB as a significant factor for pain relief (hazard ratio: 1.88; 95% confidence interval: 1.12-3.13; p = 0.018).
    Conclusion: The combination of ACB with LFCN block during ACL reconstruction significantly reduced pain in the early postoperative period compared to FNB with LFCN block.

    Abstract Objectives: This study aimed to identify vocal fold leukoplakia (VFL) lesions on the inferior surface as a risk factor for recurrence.
    Methods: This was a retrospective study with data collected from 2001 to 2018. The study comprised 37 patients with VFL, divided into the nonrecurrent and recurrent groups. We examined the clinicopathological characteristics and the surgical procedures performed in each patient.
    Results: Among the 37 patients, 15 (40.5%) had residual (3) or recurrent (12) VFL. Of those patients with and without recurrence, 8 of 12 (66.7%) and 6 of 22 (27.3%), respectively, had inferior surface lesions of the vocal fold at the initial operation (
    Conclusion: The presence of VFL lesions on the inferior surface is a significant risk factor for recurrence.

    Abstract Thyroid hyalinizing trabecular adenoma (HTA) is a rare and borderline tumor of follicular origin. It is characterized by a trabecular growth pattern and marked intratrabecular hyalinization. Excessively elevated thyroglobulin levels have not been reported previously in cases without bilateral lung metastases. Here, we present a case of a 54-year-old woman with chronic thyroiditis with a 50-mm tumor in the left lobe of the thyroid gland, which was observed on ultrasonography. Her thyroglobulin level was found to be elevated at 684 ng/ml. Since fine needle aspiration cytology could not exclude possible malignancy, she underwent thyroid lobectomy; the final diagnosis was thyroid HTA. Two weeks after resection, her thyroglobulin level showed negative conversion. To our knowledge, this is the first report of a patient with a thyroid HTA exhibiting a thyroglobulin level as high as that for a patient with hyalinizing trabecular carcinoma.
