Ectopic thyroid is defined as any thyroid tissues not located in the usual site of the thyroid gland, which is anterolateral to 2-4th tracheal rings in the lower neck. These tissues could be present anywhere along the descending tract of a developing thyroid primordium. It is rare for dual ectopic thyroid to have two ectopic foci simultaneously. Twenty-seven cases of dual ectopic thyroid have been reported in the English literature. Physical examinations are usually performed for oral cavity, oropharynx and anterior neck to test for thyroid function, and CT scanning and thyroid scintigraphy are usually performed for the diagnosis of these entities. We report a 19-year-old male with dual ectopic thyroid tissues in lingual and suprahyoid regions but without thyroid tissue in its normal area.

만성 비부비동염에서 Biofilm이 수술 후 경과에 미치는 영향

Background and ObjectivesZZBacterial biofilm is thought to contribute to the progression and persistence of chronic rhinosinusitis. There are many studies which demonstrate these structures on chronic rhinosinusitis (CRS), but the majority of the studies just focus on the documentation of their presence and the method for identification. There are also a few researches that show the impact of biofilm on postoperative surgical outcomes. In this study, we demonstrated bacterial biofilm in CRS patients and determined whether they affect clinical courses and outcomes after surgery. Subjects and MethodZZThe mucosa of ethmoid bulla was obtained during endoscopic sinus surgery from 21 CRS patients. Fluorescent microscope and scanning electron microscopy (SEM)were used for the determination of biofilm. The outcomes of the surgery were evaluated by endoscope every two weeks for 6 months. Preoperative symptom scores, CT scores, and the post operative results were compared between patients with biofilm and patients without biofilm. ResultsZZBacterial biofilm were seen in 13 (62%) of the 21 CRS patients. A statistical association existed between the presence of biofilm and the worsened preoperative symptom scores,but the preoperative CT scores were not related to the presence of biofilm. Patients with biofilm had long-lasting postoperative mucosal inflammation and a prolonged healing time, and these differences have statistical significance. ConclusionZZThis study showed that the presence of bacterial biofilm were significantly correlated with worsening preoperative symptom scores and the prolonged postoperative recovery time. Therefore, bacterial biofilm may play an important role in the recalcitrant and resistant nature of CRS. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:349-53
