Objective:This article explores the diagnosis and treatment of a special type of laryngeal foreign body with granuloma in children, providing a clinical reference for standardized diagnosis and treatment. Methods:This article retrospectively analyzes one case admitted to our department and five other cases reported in relevant literature involving a special type of laryngeal foreign body with granuloma in children. It summarizes the clinical characteristics of this disease and explores its diagnosis and treatment. Results:①A total of 6 cases were misdiagnosed and had a long course of illness. Five cases had no clear history of foreign body at the first visit. One case had foreign body history but no foreign body was found. ②The clinical symptoms were diverse, which could be hoarseness, cough, wheezing, dyspnea, or no symptoms. ③A total of 3 cases were diagnosed by laryngoscopy, and 3 cases were diagnosed by laryngoscopy and imaging examination. ④Foreign bodies that were not wrapped in granulomas, were removed first and then the granulomas were treated; foreign bodies wrapped in granulomas were removed after the removal of granulomas. Conclusion:A special type of laryngeal foreign body with granuloma may lack of accurate foreign body history, resulting in long-term retention of foreign bodies, leading to granuloma formation and misdiagnosis. Electronic laryngoscopy combined with CT examination contribute to early diagnosis. Low temperature plasma under endoscope and anesthetic laryngoscope is conducive to the exposure and precise removal of foreign bodies and avoids tracheotomy to a certain extent.

Infantile hemangiomas are relatively common soft tissue tumors in infants and young children, with a prevalence of about 4.5% in full-term newborns. Subglottic Hemangioma （SGH） is a relatively rare type of hemangioma, and its special location often causes respiratory distress and potentially life-threatening conditions in infants. Therefore, it is necessary for clinicians to make an accurate diagnosis and formulate a detailed treatment plan based on the clinical manifestations, the auxiliary examinations, the medical history and the vital signs evaluation of patients.This review describes the pathophysiological mechanism of infantile hemangioma and provides a detailed discussion on commonly used treatment methods in detail.

Objective:To explore the clinical manifestations,the type of pathology, treatment and prognosis of laryngeal rhabdomyosarcoma, and to enhance the understanding of the clinical characteristics of the disease, while improving the diagnosis rateand reducing the misdiagnosis rate, in order to explore effective diagnosis and treatment methods. Methods:A retrospective analysis was conducted on the clinical data of 5 cases of laryngeal rhabdomyosarcoma treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2021. Results:All 5 cases of laryngeal rhabdomyosarcoma were misdiagnosed in the early stage. with tumors mostly occurring in the vocal cords and appearing as smooth mass. The clinical symptoms were mostly hoarseness. According to pathological classification, three cases were embryonic type, one case was polymorphic type, and one case was spindle type.Three patients died due to tumor recurrence, one patient had multiple systemic metastases, and another patient who underwent surgical resection in the early stage and supplemented with postoperative radiotherapy and chemotherapyhas been followed up to date without recurrence. Conclusion:Laryngeal rhabdomyosarcoma has low incidence rate, high malignancy degree and poor prognosis. It is easy to be misdiagnosed as a benign mass. Extensive surgical resection combined with radiotherapy and chemotherapy should be performed as soon as possible after diagnosis.

Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.

Neuroendocrine carcinoma(NEC) is a malignant tumor derived from neuroendocrine cells, with distinct clinical, morphological and immunohistochemical characteristics. Neuroendocrine carcinoma of the head and neck is very rare in clinic. Larynx is the most common affected site, and the root of the tongue is extremely rare. The clinical manifestations are mainly eating pain, cauliflower like mass in the mouth, and ulcerative lesions that have not healed for a long time. Maxillofacial MRI and contrastenhanced CT are the most commonly used examination tools for such diseases, which can detect the spaceoccupying lesions of tumors. Neuroendocrine granules found in the cytoplasm under pathological light microscope can be diagnosed as neuroendocrine carcinoma. However, for most cases, it is difficult to make a diagnosis only under light microscope, and it is often necessary to make a diagnosis by means of immunohistochemistry and other technical means. This paper reports a case of neuroendocrine carcinoma of the root of the tongue, introduces its characteristics, diagnosis and treatment, and reviews the relevant literature of this case.

Objective: To establish a rat model for laryngeal precancerous lesions histologically and pathologically comparable to the human counterpart. Methods: Thirty-six Wistar rats were randomly divided into experimental group and control group, with 18 rats in each group, and 1% 4-nitroquinoline-1-oxide (4NQO) solution and saline were respectively applied to the laryngeal mucosas of rats in two groups. During subsequent 20 weeks, the changes of laryngeal mucosas were regularly observed with naked eyes and endoscope and lesions were determined by histology. SPSS 22.0 software was used for statistical analysis. Results: The food intake, water intake and body weight of the rats in the experimental group were lower than those in the control group, with statistically significant differences (all P<0.05). White plaque, superficial ulcer, erosion and miliary particles were present in the larynxes of rats in the experimental group, with histological manifestations of atypical hyperplasia or carcinoma in situ, and normal epitheliums were shown in the control group. The number of Ki67 positive cells in the laryngeal mucosas of rats in the experimental group at the 4 th, 8 th, 12 th, 16 th, and 20 th weeks were 13.5±2.4, 35.6±5.8, 53.4±8.3, 78.8±11.6, 80.6±12.4, respectively, no Ki67 positive cells were found in the control group at individual time points, and the differences were statistically significant (t=9.74, 10.63, 11.14, 11.77, 11.26, respectively, all P<0.01). Conclusion: 4NQO can credibly cause rats laryngeal precancerous lesions, which morphologically and histologically mimic laryngeal carcinnogenesis. This method is practical, easy and reliable to prepare the animal model of laryngeal precancerous lesions.

Objective: To evaluate the efficacy of surgical treatment of papillary thyroid carcinoma (PTC) involving larynx and trachea. Methods: A total of 1 436 cases of thyroid malignant tumors were admitted to the Department of Otolaryngology, Qilu Hospital of Shandong University from 2004 to 2019, including 110 cases of PTC involving larynx and trachea, and of which 105 cases with complete follow-up data were retrospectively analyzed. There were 42 males and 63 females, with a male/female ratio of 1∶1.5, aged from 28 to 81 years. All lesions involved trachea, including 11 cases involving both trachea and larynx. Of those 83 cases underwent laryngeal and airway wall tumor excision, and 22 cases underwent radical tumor excision plus laryngeal and trachea repair. Extubation rate was analyzed and the postoperative survival curve of patients was analyzed by Kaplan-Meier method. Results: Among 105 cases, 16 cases underwent tracheotomy and 12 cases were successfully extubated. The overall 3- 5- and 10-year survival rates were 100.0%, 86.4% and 72.5%, and the disease-free survival rates were 93.1%, 81.6% and 57.7%, respectively. There was significant difference in survival curve between the two groups (χ²=4.21, P=0.040). The 5-year and 10-year survival rates were 94.6% and 77.3% in laryngeal and tracheal tumor exclusion group, and 85.7% and 51.4% in the radical tumor resection group. There was no significant difference in the survival curves between the two groups (χ²=3.50, P=0.061). Conclusion: PTC patients with laryngeal and tracheal involvement can achieve long survival and good quality of life through reasonable surgical treatment.
