Sialadenoma papilliferum (SP) is a rare benign salivary gland neoplasm. SP comprises 0.4–1.2 % of minor salivary grand tumors. Age at diagnosis peaked in 60 s and an average age of 56.4 years. SP cases are somewhat more common in males(female/male=1:1.5). Herein, we present a rare case of a SP occurred in 80 s female. The patient underwent surgical resection and had no regrowth 10 months later. Although regrowth of SPs is rare, there have been reports of regrowth or malignant transformation of them, so we will follow up carefully.

Chylothorax following neck dissection rarely occurs on the contralateral side and typically develops ipsilaterally or bilaterally. Herein, we report an unusual case of bilateral pleural effusion and right-sided chylothorax after left neck dissection in an 81-year-old man. The patient presented with contact pain on the left tongue edge, which was caused by an ill-defined 12 × 6 mm ulcerative lesion with induration. His medical history included polio, and preoperative tests showed restrictive ventilatory impairment. The patient was diagnosed with left-sided tongue cancer (squamous cell carcinoma, T2N1M0) and underwent partial left glossectomy, left neck dissection, and tracheostomy. Postoperatively, pale-yellow fluid draining from the neck suggested chyle leakage, prompting supraclavicular fossa compression. By the seventh day, the bilateral pleural effusion had caused respiratory failure, and the patient required positive-pressure ventilation. Tube feeding was replaced with central venous nutrition on the tenth day. Right chylothorax was confirmed on the eleventh day. Low-fat tube feeding was resumed on Day 27, without chylothorax recurrence. The etiology of the right-sided chylothorax after left neck dissection was attributed to increased intralymphatic pressure from thoracic duct ligation and neck compression, causing duct rupture and lymph fluid spreading to the thoracic cavity via the mediastinum. This case highlights the need for careful post-neck dissection management because of the risk of severe respiratory failure due to chyle leakage.

Rhabdomyosarcoma is a malignant soft-tissue tumor of mesenchymal origin, that mainly occurs in children. The current World Health Organization classification recognizes four distinct subtypes of rhabdomyosarcoma based on clinicopathological and molecular genetic features. The sclerosing type is less common with no standard treatment. The prognosis of rhabdomyosarcoma in adults and in patients with sclerosing subtypes is poor. A 31-year-old woman was referred to our hospital because of swelling of the right cheek and trismus. Clinical examination revealed a maximum mouth opening of 10 mm, and an elastic hard mass was palpated under the right buccal mucosa. Contrast enhanced computed tomography revealed a well-defined mass, approximately 30 mm in size, with heterogeneous contrast effect, in the right infratemporal fossa with bone resorption. Magnetic resonance imaging revealed low signal intensity on T1-weighted images, a heterogeneous contrast effect, and partially high signal intensity on T2-weighted images. Histopathological examination of a biopsy specimen revealed sclerosing rhabdomyosarcoma. Clinical examination indicated that complete surgical resection was possible. Accordingly, tumor resection and latissimus dorsi flap reconstruction were performed, followed by postoperative chemoradiotherapy, comprising vincristine, actinomycin D, and cyclophosphamide therapy and radiation therapy (36 Gy/20 fractions). No recurrence or metastasis was observed 45 months after surgery.

Glomus tumor is a benign tumor developing from the glomus cells at the arteriovenous anastomosis. It most frequently occurs in the skin of the fingers and toes and in the nail beds, and rarely in the oral region. An 85-year-old female patient presented to our department with a chief complaint of swelling of her upper lip. She was aware of the mass, and requested further treatment upon gradual growth of the lesion. Clinical examination revealed the mass in the center of upper lip beneath the mucosa. The lesion was an elastic soft mass measuring 16 × 14 mm in size. The mass was smooth and dark purplish in color. Magnetic resonance imaging revealed the low signal intensity in the T1 weighted image and high signal intensity in the T2 image, and mixed high and low signals within the mass. Ultrasound imaging revealed a uniform mass with a clear border, abundant blood flow signals, and enhanced posterior echoes. Histopathology confirmed the diagnosis of a glomus tumor. Since few papers have reported on the imaging findings of glomus tumors, our case findings will aid in the diagnosis of glomus tumors.

Objective
This study aims to determine whether inflammatory and nutritional indices are associated with the formation of salivary fistula or sialocele following parotid benign tumor resection.
Methods
Retrospective analysis of 373 parotid tumor resection patients evaluated preoperative inflammatory or nutritional indices for predicting postoperative salivary fistula or sialocele. Binary logistic regression identified independent risk factors to construct a nomogram.
Results
Salivary fistula or sialocele occurred in 115 patients, yielding an incidence rate of 30.8 %. Binary logistic regression analysis demonstrated that postoperative duration of drainage, HALP score (Hemoglobin-Albumin-Lymphocyte-Platelet score) ≥ 49.2, and PNI (Prognostic Nutritional Index) ≥ 52.68 served as protective factors against salivary fistula or sialocele formation. Conversely, smoking was identified as a risk factor for salivary fistula or sialocele development, with all P-values < 0.05. Conclusions: HALP score, PNI, smoking, and duration of drainage are independent predictors of the occurrence of salivary fistula or sialocele after parotid benign tumor resection. The nomogram incorporating the indicators mentioned above can serve as a reference for clinicians to assess the occurrence of salivary fistula or sialocele following parotid benign tumor resection.

Bone has a natural self-healing ability through the interaction of osteoblasts and osteoclasts under physiological conditions. However, when defects exceed the critical size due to congenital anomalies, trauma, inflammation, periodontal diseases, tumor resection, or surgical interventions, alveolar bone regeneration becomes challenging. Autologous bone grafting is the gold standard for alveolar bone defects but has drawbacks such as donor site morbidity and infection risks. Allografts also pose challenges, including immune responses and limited bone formation. Tissue engineering presents an alternative, utilizing bioactive scaffolds, osteogenic cells, and growth factors to create a biomimetic environment that enhances regeneration. This review explores the fundamentals of tissue engineering and its application in bone reconstruction. It first discusses the key components of tissue engineering, including cells, scaffolds, and growth factors in bone tissue engineering. This is followed by an overview of their integration with recent advancements in 3D-printed scaffolds for alveolar bone regeneration.

Carcinoma ex pleomorphic adenoma (CXPA) is a malignant tumor that develops from pleomorphic adenoma (PA) and rarely occurs in the minor salivary glands. The malignant components are most frequently classified as adenocarcinoma not otherwise specified or salivary duct carcinoma. A search of the literature revealed only one previous report of myoepithelial carcinoma ex pleomorphic adenoma (MEC-exPA) in the upper lip. In this report, we present a second case. A 74-year-old man presented with a 15-year history of a mass in the left upper lip. The tumor was resected under general anesthesia. Histopathological examination of the resected specimen showed a biphasic composition with PA areas and malignant changes. The carcinoma comprised atypical myoepithelial cells expressing both myoepithelial and epithelial markers. Based on these findings supported by immunohistochemical results, the final diagnosis was MEC-exPA. No signs of recurrence or metastasis have been observed as of two years after surgery.

To perform a comprehensive analysis of the three-dimensional effects of Le Fort I osteotomy (LFI) on the nasolabial region in skeletal class III patients by evaluating the three-dimensional movement of the maxilla and assessing its relationship with three-dimensional changes in nasolabial soft tissues.
Methods
This retrospective study included 20 skeletal class III patients (8 men and 12 women; mean age: 25.0 ± 8.2 years) who underwent LFI using SuperFIXSORB-MX®. We investigated the correlation between maxillary movement and nasolabial soft tissue changes following LFI with detailed three-dimensional computed tomography by surface superimposition preoperatively (T0), 4 days postoperatively (T1), and 1 year postoperatively (T2). The “surgical maxillary movement” was evaluated by surface superimposition of virtual LFI segments at T0 and T1. The “soft tissue change” was evaluated by superimposing an unchanged cranial section of T0 and T2 and measuring the soft tissue reference points set on the soft tissue sections of T0 and T2.
Results
The upward movement of the pronasale and the anterior movement of the subnasale, labiale superior, and alare creases were significantly positively correlated with the anterior movement of point-A; only the labiale superior was significantly positively correlated with the upward movement of point-A. However, the external nasal morphology was not significantly correlated with the movement of point-A.
Conclusions
Using the preoperative virtual skull section as a reference enabled a highly detailed evaluation of maxillary movement and corresponding soft tissue changes. This method is expected to contribute to more effective surgical planning and improved patient informed consent.
目的通过评价上颌骨的三维运动及其与鼻唇区软组织三维变化的关系，综合分析Le Fort I型截骨术（LFI）对骨骼III类患者鼻唇区的三维效果。方法本回顾性研究纳入20例骨骼III级患者（8男12女，平均年龄：25.0 ± 8.2岁），均采用SuperFIXSORB-MX®进行LFI治疗。我们通过术前（T0）、术后4天（T1）和术后1年（T2）的详细三维计算机断层扫描（表面叠加）研究了LFI后上颌运动与鼻唇软组织变化的相关性。通过虚拟LFI节段在T0和T1的表面叠加来评估“手术上颌运动”。通过叠加T0和T2不变的颅骨切片，测量T0和T2软组织切片上设置的软组织参考点来评估“软组织改变”。结果鼻前、鼻下、唇上、鼻翼皱褶的前运动与a点的前运动呈显著正相关；只有上唇与a点的上移呈显著正相关。外鼻形态与a点运动无显著相关。结论术前虚拟颅骨切面作为参考，可以非常详细地评估上颌运动和相应的软组织变化。该方法有望有助于更有效的手术计划和改善患者知情同意。

Ductal papilloma is a rare benign tumor that occurs in the oral cavity. Intraductal papilloma has been classified as a subtype of ductal papilloma in the WHO classification since 2024. We report the case of a patient who developed intraductal papilloma of the left buccal mucosa. The patient was a 45-year-old female, who was referred to our department for a mass on her left buccal mucosa. The mass measured 10 mm in diameter. Color Doppler ultrasonography revealed internal blood flow and a well-demarcated internal spotty hypoechoic region. Therefore, tumor resection was performed under local anesthesia. The histopathological diagnosis was intraductal papilloma. There has been no recurrence for 2 years since the operation.

Objective
The Neutrophil-Lymphocyte Ratio (NLR), Platelet-Lymphocyte Ratio (PLR) and C-reactive protein (CRP) ratio are employed as prognostic indicators in a range of surgical procedures. The utilisation of these biomarkers as prognostic indicators in various surgeries suggest that they may also be usefull in oral surgeries. This study aims to determine whether NLR, PLR and CRP may be utilized as prognostic markers to predict post-operative sequelae after mandibular third molar surgery.
Methods
NLR, PLR, and CRP were obtained from routine hemogram, and biochemistry tests of the patients. Edema, trismus, pain with Visual Analog Scale (VAS), analgesic consumption (AC), and Quality of Life (QoL) were measured before and after surgery. Edema and trismus on the 2nd and 7th days, VAS scores, AC up to 7th day, and QoL on 7th day were measured post-operatively.
Results
Forty-six patients were included. Significant correlations were found between pain and NLR, and CRP during first 6, and PLR first 4 days. Significant positive correlations were found between AC and NLR and CRP on all days. Significant relations were found between PLR and AC on the 3rd and 4th days. Significant positive correlations were found between operation time and trismus, edema, and QoL. NLR and CRP were found more successful in predicting AC and pain than PLR.
Conclusion
These results suggest that NLR, PLR, and CRP are useful predictors that can be utilized to improve pain management, augment patient comfort throughout the healing process, and implement the required adjustments to treatment approaches.
