ABSTRACT
BACKGROUND AND OBJECTIVES: Drug-induced sedation endoscopy (DISE) has recently gained popularity among otolaryngologists because it can provide direct information of upper airway obstruction in patients with obstructive sleep apnea (OSA). In that regard, we examined how DISE examination affected the decision of clinician's treatment plan and the consequent patient's compliance in OSA patients. SUBJECTS AND METHOD: All enrolled patients were classified into two groups according to the method of upper airway evaluation employed: a physical examination only group and a physical examination combined with DISE group. The clinician's treatment plan was categorized into the following four groups: sleep surgery, positive airway pressure, oral appliance, and sleep surgery combined with oral appliance. The change of patient's compliance was also evaluated. RESULTS: There were several differences in how DISE evaluation affected the decision of clinician's treatment plan and patient's compliance between the two groups. The rate for sleep surgery fell from 69.6% to 15.9%; on the other hand, the rate for positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 13.0% to 36.2%, 14.5% to 26.6%, and 2.9% to 21.3%, respectively. The patient's compliance also changed after DISE evaluation: sleep surgery, positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 78.1% to 87.9%, 16.7% to 76.0%, 25.0% to 87.3%, and 50.0% to 91.03%, respectively. CONCLUSION: We found that DISE examination influences the decision of clinician's treatment plan and patient's compliance. We suggest additional cohort studies to confirm these findings.

Sebaceous carcinoma of the salivary gland is an extremely unordinary malignancy occurring mainly in the parotid gland. Sebaceous carcinoma arising in the submandibular gland is exceptional and only three cases have been reported in the literature. We herein present a unique case of sebaceous carcinoma of the submandibular gland, the first to be reported in literature in South Korea. An 85-year-old man visited our hospital complaining of a progressively enlarging submandibular mass with tenderness and ipsilateral facial palsy. We performed a wide excision of the mass with superficial parotidectomy and modified neck dissection. Microscopic and immunohistochemical examinations demonstrated sebaceous carcinoma of low grade differentiation. Further adjuvant radiotherapy was rejected and the patient was followed up for five months. The optimal treatment of sebaceous carcinoma of the salivary gland is still not established due to the rarity of the disease. When more cases are reported, the clinicopathologic characteristics will be better understood.

Removing of foreign bodies in the external auditory canal is commonly observed in the otorhinolaryngologic field. Sometimes the size of some materials might change after being embedded in the canal; in such situation, debulking procedures are usually performed to reduce the size of the materials stuck there. But if it is hard to shrink the materials' size, we should consider other procedures. Here we present a minimized procedure utilized to remove nettlesome fragments of industrial cement via 3-dimensional reconstruction of temporal bone computed tomography and partial canaloplasty through transcanal approach.

OBJECTIVES: Pediatric sleep-disordered breathing (SDB) is a common debilitating disorder that can adversely affect the attention and academic performance of school-age children. Unfortunately, only a few studies have examined the effect of SDB treatment on attention in pediatric populations. Therefore, the aim of this study was to prospectively investigate the effect of SDB treatment on attention in children. METHODS: This study consecutively enrolled SDB children with adenotonsillar hypertrophy. All subjects underwent standard-of-care treatment (adenotonsillectomy or close observation) and were evaluated using a computerized comprehensive attention test at the initial visit. Comprehensive attention tests consisted of both sustained and divided attention tasks. Each completed task was assigned an attention score, which was based on the number of omission or commission errors. The comprehension attention test was repeated 1 year later. RESULTS: A total of 171 children who underwent adenotonsillectomy and 32 children who did not undergo adenotonsillectomy were included in this study. At baseline, there was no significant difference according to the score of all type comprehension attention tests between children in the adenotonsillectomy group and in the observation group. One year after treatment, children in the adenotonsillectomy group had significantly improved scores in all attention tasks. Children in the observation group had only significant improvement in omission errors on sustained attention tasks. Meanwhile, the attention score based on commission errors of divided attention tasks was significantly worse than at baseline for those. CONCLUSION: Our study showed that adenotonsillectomy may be helpful in improving attention in children with SDB.

BACKGROUND AND OBJECTIVES: Recently, mandibular advancement device (MAD) has been used widely used for the treatment of obstructive sleep apnea (OSA) because it can effectively reduce the collapsibility of upper airway during sleep. Although MAD is widely prescribed by otorhinolaryngologists, several studies described its complications arising from the anterior placement of the mandible with long-term use. However, there is still a lack of studies on long-term complications in Korean patients. SUBJECTS AND METHOD: Retrospectively, we included a total of 57 OSA patients in the study. In this study, all enrolled OSA patients had used MAD over two years with more than 4 hours/day. Dental consulting and cephalometric analysis were conducted to identify the change of dental and skeletal findings at two different times (baseline and after 2 year). RESULTS: The dental findings showed that the overbite and overjet were significantly decreased. Additionally, the proclination of the lower incisors were increased significantly, whereas there was no significant change on the retroclination of the upper incisors. Three patients showed a change of malocclusion type. On the analysis of skeletal findings, we found a significant increase in the sella turcica central point-nasion-supramental point angle and a decrease in the subspinal point-nasion-supramental point angle. Moreover, the anterior lower facial height and anterior facial height were significant increased. CONCLUSION: Consistent with Western studies, our findings suggest that the long-term use of MAD could induce changes in dental and skeletal morphologies in Korean OSA patients. Therefore, clinicians should thoroughly evaluate potential changes in dental and skeletal morphologies when they prescribe MAD to patients with OSA.

BACKGROUND AND OBJECTIVES: Application of automatic positive airway pressure (APAP) is regarded as the primary therapy for patients with obstructive sleep apnea syndrome (OSAS). However, a low adherence rate is a major problem with APAP treatment in OSAS patients. Therefore, the aim of the present study is to assess factors related to good adherence of APAP therapy in OSAS Korean patients. MATERIALS AND METHOD: Of 112 consecutive newly diagnosed moderate to severe OSAS patients, 70 were enrolled in this study. All patients received APAP therapy for 2 weeks, along with reinforcing intervention, consisting of motivational reinforcement and technical support. All APAP therapy involved a device rental service. After 2 weeks of treatment, patients had to choose the kind of treatment for OSAS [APAP therapy (good adherence) or alternative treatment options (poor adherence)]. RESULTS: After 6 months, the adherence rate to APAP therapy was 35.7% (n=25). No statistically significant difference was observed between the good and poor adherence groups with regard to snoring intensity, apnea-hypopnea index, and mean O2 saturation after adjusting for age, sex, body mass index, marital status, and socioeconomic status. However, we found that excessive daytime sleepiness and lowest O2 saturation were significantly associated with good adherence [adjusted odds ratios (ORs)=9.515 and 2.327] after adjusting for age, sex, body mass index, marital status, and socioeconomic status. CONCLUSION: Our findings suggest that excessive daytime sleepiness and lowest O2 saturation are important factors to identify good adherence to APAP treatment in Korean OSAS patients.
