Pharyngeal and laryngeal foreign bodies are common problem at ENT clinic. Removal of a foreign body is mostly simple with the manipulation of endoscope and various instruments. Rarely, migration of swallowed sharp foreign body makes complication. We describe a 74-year-old patient diagnosed with foreign body in larynx involving thyroid. In this case, we present this disease and the treatment course which has been successfully treated by surgical removal and conservative treatment. Furthermore, we discuss its symptoms, physical examinations through literature review.

Esophageal foreign bodies are common problems in the part of otolaryngology department, and may cause severe complications such as esophageal ulceration, esophageal perforation, periesophagitis, tracheoesophageal fisula, pneumothorax and pyothorax. Therefore, early diagnosis and intervention is needed to reduce morbidity and motality. But, calcification of the laryngeal cartilages may masquerade as foreign body in some patients with a history of foreign body ingestion. Recently, We experienced a case of calcification of thyroid cartilage which was misunderstood as an esophageal foreign body and report this case with a review of literatures.

Background and Objectives : Globus pharyngeus is the feeling of a lump or foreign body in the throat. Otolaryngologists are often confronted with this condition, and some author reported that it represents 3 percent of all new clinic referral. The purpose of this study is to estimate the incidence of impalpable thyroid lesion in patients with globes pharyngeus and investigate possible association between globus pharyngeus and thyroid lesions. Material and Method : 146 patients with globus pharyngeus and 30 controls were prospectively examined by high resolution ultrasound. Results: Thyroid abnormalities were present in $75/146(51\%)$ patients with globus pharyngeus and in $7/30(23\%)$ controls. Of the patients with globus, 55 patients had a nodule or nodules, 11 patients had a cyst or cysts, 9 patients had diffuse abnormalities. Solitary nodule ranged from 4mm to 20mm. Conclusion : Impalpable, ultrasound detectable thyroid abnormailities are significantly more common in patients with globus pharyngeus than in controls. The thyroid abnormalities may be the cause of globus symptoms in some patients, and high resolution ultrasound is an important modality in patients presenting with globus.

Objectives : This study was aimed to investigate soft tissue reaction such as inflammation, immune reaction of rabbit larynx to implanted foley catheter. Methods : After 8 rabbits were anesthetized, their thyroid cartilage and trachea were exposed through a skin incision and a 6 French foley catheter was inserted into the thyroid cartilage via cricothyroid membrane and ballooned with normal saline (0.1 mL). The other end of catheters were ligated and cut. The wound was closed keeping catheter under the skin. Two rabbits were used as normal control Larynges were removed for pathologic examination at 4weeks and 8 weeks of the study respectively, Results : Ten rabbits were euthanized for gross and pathologic examination (5 rabbits after 4 weeks and 5 rabbits after 8 weeks). All rabbits survived the study periods and inflammations or foreign body reactions were minimally found on pathologic examinations. Conclusions : Foley catheter could be useful and safe material for vocal fold medialization in rabbit models.

A lingual thyroglossal duct cyst(LTGDC) is a rare congenital anomaly that account for only 0.5% to 2% of total thyroglossal duct cyst. LTGDC is frequently associated with respiratory problem in infants and pharyngeal foreign body sensation or dysphagia in adults. Because of its location and characteristics, lingual thyroid, dermoid cyst, and vallecular cyst should be included in differential diagnosis. Standard treatment for thyroglossal duct cyst is sistrunk's operation, but in terms of LTGDC, because of its location and cosmetic reasons, different kinds of treatments such as electrical cauterization, $CO_2$ laser, Robort surgery via transoral approach have been introduced. Recently authors encountered 21 years old woman with LTGDC and the mass was removed successfully via transoral approach using $CO_2$ laser. We report the clinical course with review of the literature.
