, Seung-Sin Lee Obstructive sleep apnea syndrome (OSAS) is caused by repetitive upper-airway narrowing or collapse during sleep resulting in hypopneas and apneas. When a patient is diagnosed of OSAS with polysomnogram, he/she should receive upper airway evaluation to find the narrow site. The anatomic narrow site can be nasal cavity, nasopharynx, oropharynx, and/or hypopharynx. Surgical treatment for OSAS should be tailored to the anatomic narrow site. In this article, the authors describe surgical treatment options for OSAS.
The pathogenesis of fungus ball has been unclear yet. This study was performed to find a clue to the pathogenesis of fungus ball and to clarify the role of ostiomeatal unit(OMU) obstruction in the fungus ball through the comparative study of fungus ball and chronic bacterial sinusitis.
35 patients with fungus ball(fungus group) and 42 patients with chronic unilateral bacterial sinusitis(bacteria group) were analyzed in terms of radiologic findings and endoscopic findings.
Fungus ball was observed in older patients than chronic bacterial sinusitis(59.7 vs. 41.1). The total Lund scores of bacteria group were higher than those of fungus group(6.0 vs. 4.6)(
This study may suggest that fungus ball is not associated with the obstruction of OMU comparing with chronic bacterial sinusitis and that fungus ball has another pathogenic mechanism different from that of bacterial sinusitis.
