Laryngeal cyst is a cystic lesion occurring in the laryngeal cavity. Large laryngeal cyst in infants and young children can cause laryngeal wheezing and other upper airway obstruction symptoms. In severe cases, it can be even life-threatening and requires timely surgical treatment. Currently, there is a lack of unified clinical treatment strategy for this disease.This article summarizes the surgical methods, the advantages and disadvantages of various surgical methods for laryngeal cysts in recent years. It is recommended that needle aspiration, partial cyst wall resection, radical cyst dissection, transoral robotic surgery or external approach cyst resection should be selected through full communication and evaluation to clarify the extent of the lesion scope and the advantages and disadvantages of surgery.

The ex utero intrapartum treatment (EXIT) procedure was introduced to reduce fetal hypoxic damage while establishing an airway in fetuses with upper and lower airway obstruction. Delivery of the fetal head and shoulders while maintaining the uteroplacental circulation offers time to secure the fetal airway. Here, we report two cases of EXIT procedure for fetal airway obstruction, which were successfully managed with extensive preoperative planning by a professional multidisciplinary team.

BACKGROUND: Construction site supervisors are exposed to many chemicals, dusts, and metals including asbestos. Asbestos is a hazardous chemical that is carcinogenic. Laryngeal cancer is not a rare disease in Korea. The most common causes of this disease are tobacco and alcohol, and representative occupational cause is asbestos. However, up to now, no case of laryngeal cancer induced by asbestos has been reported in Korea. In this study, we report such a case in a construction site supervisor. CASE PRESENTATION: A 60-year-old man who had been experiencing hoarseness for 2 months was diagnosed with laryngeal cancer. The pathologic diagnosis was squamous cell carcinoma in situ, based on examination of a biopsy specimen obtained by resection of the lesion. The patient had been exposed to asbestos for 38 years at construction sites where he worked until diagnosed with laryngeal cancer. He had been exposed to asbestos when demolishing buildings and inspecting materials. CONCLUSION: The patient in this case worked with construction materials including asbestos and supervised construction for 38 years, and was thus exposed to asbestos at construction sites. Much of the asbestos was highly concentrated especially during demolition processes. We therefore consider the laryngeal cancer of this patient to be a work-related disease.

OBJECTIVE: To discuss the diagnosis and treatment method in children with mass in subglottic. METHOD: There were totally 35 patients with subglottic mass who complained with dyspnea in our department. All the patients got electronic laryngoscopy examination in order to get the preliminary judgment of the mass' property. Then they accepted ultrasound and CT scan to make the definite diagnosis. The patients with subglottic hemangioma accepted oral propranolol or intralesional Pingyangmycin injection. The other type of masses got the laryngoscope CO2 laser tumor resection. RESULT: There were 31 patients with subglottic hemangiomas, 2 patients with subglottic cysts, 1 patient with subglottic fibroma, 1 patient with subglottic granuloma. The substantial follow-up time was from 1 month to 3 years. 25 patients with subglottic hemangiomas were cured, 6 patients got improvement. The patients with non-hemangiomas were all cured. CONCLUSION There was a high incidence of hemangioma in children with subglottic mass. We suggested making a diagnosis by doing electronic laryngoscopy, ultrasound and CT scan step by step. Oral propranolol was a safe and effective method in treating subglottic hemangioma. For the patients with non-hemangiomas, we considered the laryngoscope CO2 laser tumor resection as the first choice of treatment.

OBJECTIVETo discuss the effect of electric coagulation through bronchoscopy in diagnosis and treatment of congenital vallecular cyst in children.

METHODTen cases of congenital vallecular cyst in the study with age ranged from 21 days to 4 years and 10 months were treated with electric coagulation through bronchoscopy. The therapeutic effect was evaluated by endoscopic and clinical manifestation. And all the patients were followed-up for 6-12 months.

RESULTAll the patients obtained 3-5 times electric coagulation. After the operation, the cyst decreased in size, epiglottis softening was subsided, uplift uncompression, dyspnea and laryngeal stridor were improved obviously. After follow-up periods of 6-12 months, no capsule wall were left, and the activity of the epiglottis resumed.No severe complication was found in any patient.

CONCLUSIONElectric coagulation through bronchoscopy is a simple, effective and safe method to treat congenital vallecular cyst in children.

OBJECTIVETo study the clinicopathologic features, histologic diagnosis and differential diagnosis of primary mucosal tuberculosis (TB) in the head and neck region.

METHODSForty-seven cases of primary mucosal TB of the head and neck region were studied by hematoxylin-eosin and Ziehl-Neelsen stains. The clinical and pathologic features were analyzed with review of the literature.

RESULTSThe patients included 26 male and 21 female, with mean age 47.1 years (range 14-84 years). There were three sinonasal TB, 19 nasopharyngeal TB, two oropharyngeal TB, 18 laryngeal TB, four middle ear TB, one salivary gland TB and one laryngeal TB complicating laryngeal cancer. The initial symptoms were nasal obstruction, mucopurulent rhinorrhea, epistaxis, snoring, hoarseness, dysphagia, odynophagia, serous otitis, hearing loss, tinnitus, and otalgia. Physical examination result was variable, from an apparently normal mucosa, to an evident mass, or a mucosa with an adenotic or swollen appearance, ulcers, leukoplakic areas, and various combinations thereof. CT and MRI findings included diffuse thickening, a soft-tissue mass, calcification within the mass and bone destruction resembling malignancy. Histologic examination showed granulomas with a central necrotic focus surrounded by epithelioid histiocytes and multinucleated Langhan's giant cells. Acid-fast bacilli were difficult to demonstrate but found in 13/45 cases. Follow-up data were available in 42 patients.

CONCLUSIONSPrimary TB arising in the head and neck mucosa is rare. It may mimic or co-exist with other conditions. The characteristic histopathology is a granuloma with central caseous necrosis and Langhans'giant cells. Identification of acid-fast bacilli and bacteriologic culture confirm the diagnosis of mycobacterial disease.

Although rare, vallecular cysts can have catastrophic consequences in an anaesthetised patient if airway management is inappropriate. We report a case of difficult intubation in a 46-year-old man with a vallecular cyst, and detail the methods and strategies for successful endotracheal tube insertion. Following a review of the current literature, we also discuss airway management options in adult patients with vallecular cysts.
