Previous anatomic concepts in cleft lip nose deformity have following characteristics: 1. Obtuse angle between medial and lateral crus in affected alar cartilage; and 2, Cleft side alar cartilage is hypoplastic. The purpose of this study was to review the anatomy of alar cartilage in cleft lip nose deformity and to find out the effects of removal of intercartilagenous soft tissue on the effects of removal of intercartilagenous soft tissue on relocation of alar cartilage. There were 97 cleft lip nose corrections from Oct. 1996 to March When the affected alar cartilage was dissected, redundant intercartilagenous fibro-fatty tissue was found. After removing this redundant soft tissue, we found that the cleft side alar cartilage was better adjusted to the normal position. In addition, the plicavestibularis was more improved. Alar cartilage suture fixation was subsequently performed. Alar cartilage suture fixation was subsequently performed. After this procedure, we found that subsequently performed. After this procedure, we found that the affected side of alar cartilage was more normally positioned than before. The summary of the author's view on affected alar cartilage is as follows: 1. An acute angle between the medial and lateral crus was noted in affected alar cartilage; 2. Redundant intercartilagenous fibro-fatty tissue was present in cleft lip nose deformity;3.The terminal portion of the lateral crus of alar cartilage makes a plica vestibularis in the cleft side; 4. The position of the medial crus of alar cartilage was lower in the cleft side with the lateral crus was lower and cephalic in the cleft side; 5. The cleft side of alar cartilage is not hypoplastic.

Median cleft of the lower lip and/or mandible is a rare congenital anomaly, first mentioned by Couronne in 1819. Monroe(1966), Fujino(1970), Ranta(1984) and Oostrom(1996) conducted comprehensive reviews and list cases in literature. Median cleft varies greatly, from a simple vermilion notch to a complete cleft of the lip involving the tongue, the chin, the mandible, the supporting structures of the median of the neck, and the manubrium sterni. The associated anomalies include ankyloglossia, cleft tongue, neck contraction, heart lesion, absence of hyoid bone, and so on. The etiology of median cleft is unknown. Various possibilities, such as failure of mesodermal penetration into the midline, failure of fusion of mandibular processes, external factors apart from the embryogenic pattern such as prensure, position in utero, circulatory failure caused placental adhesion, diseases in pregnancy, and so on, have been discussed. A 8-year-old girl was referred to the Dept. of Oral & Maxillofacial Surgery, Kyungpook National University Hospital and had been aware of the fact that at birth "she had something wrong with her mouth." Shortly after birth she had been examined by a plastic surgeon and at that time surgical procedure had been performed to release the tongue from the lower jaw and lip at local hospital. On admission, she had a slight notching of lower lip and two fibrous frenum ran from the lip along the ventral surface of the tongue, diastema between her mandibular central incisors, and slightly constricted bifid mandible associated independent movement of the two halves of mandible. The patient had autogenous iliac bone graft to reconstruct the mandibular midline defect. The postoperative result was uneventful. In future, the correction of the soft tissue deformities such as notching of the lower lip and partial ankyloglossia will be required for the esthetic and functional improvement.

To investigate epidermiologic trend in maxillofacial fractures, We retrospectively studied 934 patients with maxillofacial fractures between 1981∼1987 and 1995∼1999. The results were compared in the previous group (Group A, patients treated between 1981∼1987) with those in the recent group (Group B, 1995∼1999). Also, we studied 516 patient between 1995∼1999 for occupation, associated injuries, treatment and complications. The sex ratio of men to women decreased (5.6 : 1 in Group A vs. 3.5 : 1 in Group B), and the largest age group was 20 to 29 years. There was the highest incidence in September and Fall. The most frequent cause of maxillofacial fracture in both Group A and B was traffic accidents. The distribution of fracture site did not change appreciably, but the frequency of midfacial fracture increased. In the recent group, the largest occupational group was salaried men, and the largest associated injuries of maxillofacial fracture was head and neck injury. Open reduction was used in 91% of the cases, and post-operation complications were infection, neurologic problem, malocclusion, and mouth opening limitation etc. Our results suggest that the clinical features of patients with maxillofacial fractures have changed during the past decade.

Correlation between the Severity of Obstructive Sleep Apnea and Heart Rate Variability Indices

Park, Doo-Heum,Shin, Chul-Jin,Hong, Seok-Chan,Yu, Jaehak,Ryu, Seung-Ho,Kim, Eui-Joong,Shin, Hong-Beom,Shin, Byoung-Hak The Korean Academy of Medical Sciences 2008 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.23 No.2

<P>The risk of cardiovascular disease is known to be increased in obstructive sleep apnea syndrome (OSAS). Its mechanism can be explained by the observation that the sympathetic tone increases due to repetitive apneas accompanied by hypoxias and arousals during sleep. Heart rate variability (HRV) representing cardiac autonomic function is mediated by respiratory sinus arrhythmia, baroreflex-related fluctuation, and thermoregulation-related fluctuation. We evaluated the heart rate variability of OSAS patients during night to assess their relationship with the severity of the symptoms. We studied overnight polysomnographies of 59 male untreated OSAS patients with moderate to severe symptoms (mean age 45.4± 11.7 yr, apnea-hypopnea index [AHI]=43.2±23.4 events per hour, and AHI >15). Moderate (mean age 47.1±9.4 yr, AHI=15-30, n=22) and severe (mean age 44.5±12.9 yr, AHI >30, n=37) OSAS patients were compared for the indices derived from time and frequency domain analysis of HRV, AHI, oxygen desaturation event index (ODI), arousal index (ArI), and sleep parameters. As a result, the severe OSAS group showed higher mean powers of total frequency (TF) (<I>p</I>=0.012), very low frequency (VLF) (<I>p</I>= 0.038), and low frequency (LF) (<I>p</I>=0.002) than the moderate OSAS group. The LF/HF ratio (<I>p</I>=0.005) was higher in the severe group compared to that of the moderate group. On the time domain analysis, the HRV triangular index (<I>p</I>=0.026) of severe OSAS group was significantly higher. AHI was correlated best with the LF/HF ratio (r<SUB>p</SUB>=0.610, <I>p</I><0.001) of all the HRV indices. According to the results, the frequency domain indices tended to reveal the difference between the groups better than time domain indices. Especially the LF/HF ratio was thought to be the most useful parameter to estimate the degree of AHI in OSAS patients.</P>

Objective: Heart rate variability (HRV) reflects the regulation of the autonomic nervous system. Panic disorder is highly associated with autonomic dysfunction, and is often accompanied by depression. The aim of this study is to determine the association between depression and HRV indices in patients with panic disorder. Methods: A total of 110 outpatients diagnosed with panic disorder participated in this study. The medical records of patients with panic disorder who visited the outpatient clinic of Konkuk University Hospital between December 2018 and March 2020 were retrospectively reviewed. Measurements used in this study include the Panic Disorder Severity Scale-Self Report, Beck Depression Inventory (BDI-II), Insomnia Severity Index, and HRV. Patients were divided into depressive and non-depressive groups based on their BDI-II scores. The association between HRV indices and depressive symptoms was statistically analyzed. Results: The low frequency/high frequency (LF/HF) ratio was reduced in patients with depression (mean = −0.095, p = 0.004 in the above moderate depressive group, mean = −0.120, p = 0.020 in the severe depressive group). Significant correlations were found between depressive symptoms and standard deviation of NN interval (SDNN) (ms) (−0.19, p = 0.044), very low frequency (VLF) (ms2/Hz) (−0.22, p = 0.021), LF (−0.25, p = 0.008), HF (−0.19, p = 0.043), and LF/HF (−0.25, p = 0.009). Multiple linear regression analysis showed that BDI predicted SDNN (ms), VLF (ms2/Hz), LF, HF, and LF/HF. Conclusion: We confirmed that the LF/HF ratio decreases when depression is accompanied by panic disorder. HRV indices may be useful markers for detecting depressive symptoms in patients with panic disorder.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. Sedativehypnotics including benzodiazepine and non-benzodiazepine have been widely used in chronic insomniacs. It is widely accepted that current hypnotics are efficient in alleviating subjective symptoms of insomnia. Non-benzodiazepine hypnotics include zolpidem, zopiclone, and melatonin. These novel non-benzodiazepine hypnotics that have efficacy comparable to benzodiazepines were developed with more understanding of benzodiazepine receptor pharmacology. Their unique pharmacologic profiles may offer few significant advantages in terms of adverse effects of benzodiazepines. However, most of hypnotics including non-benzodiazepine have some of dependence, tolerance, impaired daytime function and rebound insomnia. Currently, it is accepted that combination therapy with pharmacologic and behavioral intervention is the most effective for chronic insomniacs.
