Effects of Carbogen Inhalation and Stellate Ganglion Block in the Treatment of Idiopathic Sudden Sensorineural Hearing Loss / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Impairment of inner ear circulation may be one of the pathophysiology of idiopathic sudden sensorineural hearing loss (ISSNHL). Carbogen inhalation therapy, in which patients breathe a gas mixture of 5% CO2 and 95% O2 by mask, and a stellate ganglion block (SGB) are potent vasodilatation and tissue oxygenation procedures widely used as treatment modalities in ISSNHL. The purpose of this study was to compare the effectiveness of each modality and to find out the differences in the effectiveness of carbogen inhalation therapy and SGB. MATERIALS AND METHOD: We reviewed the records of 313 patients who were admitted to the Masan Samsung Hospital from January 1995 to December 2000 for investigation of the efficacy of carbogen inhalation therapy and SGB. One hundred and thirty-one patients were treated with carbogen inhalation, SGB and drug medication, and 57 patients without SGB and 125 patients were treated with medication only. RESULTS: Therapeutic results of carbogen inhalation and SGB group was better than that of medication only group. But no statistical differences were found between the carbogen inhalation and SGB group. CONCLUSION: These results suggest that carbogen inhalation and SGB were effective treatment modalities of ISSNHL. We recommend that carbogen inhalation therapy and SGB could be utilized as the standard treatment of ISSNHL.

A Case of Mucocele of the Submandibular Gland / 대한이비인후과학회지

Cysts of the salivary gland are non-neoplastic, localized lesions of the duct system. They form about 6 % of lesions of the salivary glands. Mucoceles represent more than 70% of the salivary cysts and usually arise from minor salivary glands; however, major salivary glands, especially the sublingual glands, may also be involved. Characteristically, mucoceles consist of a soft fluctuant bluish or translucent swelling which contain mucus, varying in size. They are most commonly found on the lower lip, but may also occur on the buccal mucosa, floor of the mouth, palate, upper lip, and tongue. They are found in all age groups but are most frequent in children and young adults. There are two types of mucoceles-one in which mucus has extravasated into the tissues (extravasation cyst) and one which is lined with epithelium (retention cyst). Recently, we experienced an unusual case of huge extravasation mucocele arising from the submandibular gland. The mucocele and submandibular gland were completely excised surgically, which were confirmed by computed tomographic scanning and histopathologic examination.
