Experience of low-temperature plasma radiofrequency treatment of 53 patients with tongue hemangioma.

BACKGROUND: The main treatments of hemangioma of the tongueare are injection of sclerotherapy, freezing, surgical resection or combined application of the above methods. It is extremely difficult to remove it completely. Even if combined with multiple methods, it is often unable to control its continued growth, and many important physiological functions of the tongue will be affected, resulting in poor quality of life for patients. OBJECTIVE: To probe into the therapeutic effect of low-temperature plasma on hemangioma of the tongue. METHODS: The clinical data of 53 patients with hemangioma of the tongue admitted to our department from July 2013 to July 2019 were retrospectively analyzed and studied. RESULTS: Low-temperature plasma radiofrequency to treat hemangioma of the tongue might have advantages of simple operation, wide vision, fewer postoperative complications and quick recovery. SIGNIFICANCE: The low-temperature plasma system possesses advantages of precise location, light collateral damage, non­carbonization of the wound surface, light postoperative response, fewer complications and faster recovery. Combined with the endoscopic system with different angles, it can fully expose the surgical field and is especially suitable for the surgical treatment of patients with tumor of the tongue, which is worth popularizing application in clinic.

[Analysis of monitoring results of Mattress-type of sleep monitoring system in elderly patients with OSAHS].

OBJECTIVE: To investigate the sleep monitoring feature of the MSMS in elderly patients with OSAHS. METHOD: One hundred and ninety patients diagnosed with OSAHS were divided into elderly group and non elderly group according to age, then the results of MSMS were analyzed. RESULT: Majority elderly patients were with mild to moderate OSAHS. The nocturnal mean blood oxygen and the lowest oxygen were higher than non elderly group, coupled with higher percentage of the total oxygen saturation < 90% monitoring time (TS90). There was no significant difference in sleep structure between two groups, but the total sleep time of elderly group is lower than the non elderly group, the difference is statistically significant. CONCLUSION: The elderly patients with OSAHS were less severe in nature, but the nocturnal hypoxia last longer in the elderly group. There is no significant difference in the sleep structure between the two groups. But the total sleep time decrease in elderly group. With smaller interference, the MSMS is closer to the natural sleep stustus of the subjects.

[The application of micro-sensitive mattress type sleep monitor in the diagnosis of OSAHS in children].

OBJECTIVE: To investigate the result of child-type micro-sensitive mattress sleep monitor on obstructive sleep apnea-hypopnea syndrome in children. METHOD: The PSG and child-type micro-sensitive mattress sleep monitor were synchronously performed on 58 cases of children with OSAHS. The breathing and sleep metrics were compared. RESULT: By PSG monitoring, 41 cases were diagnosed as mild OSAHS, 14 cases were moderate and 3 cases were severe. The results of mattress system monitoring showed mild OSAHS in 37 cases, 16 cases of moderate and severe OSAHS in 5 cases. Seven patients diagnosed as mild OSAHS monitored by PSG were classified as moderate by mattress system monitoring; three cases diagnosed as mild OSAHS by mattress system monitoring system were diagnosed as moderate by PSG. Among 14 cases of children diagnosed as moderate by PSG, three cases were diagnosed as mild by mattress system monitor and two cases as severe. Children diagnosed as severe by PSG got the same result by mattress system monitor. Two kinds of sleep monitoring methods were compared and there were no statistically significant difference in AHI (t = 2.316, P > 0.05), deep and shallow sleep constituent ratio (t = 2.280, t = 2.388, PF > 0.05). while there was significant difference in REM period Sleep constituent ratio (t = 3.135, P < 0.01). CONCLUSION: Child-type micro-sensitive mattress is in good agreement with the PSG for diagnosing OSAHS in children, which can be used as a monitoring method in clinical work.

[Coblation-assisting uvulopalatopharyngoplasty combining coblation-channeling of the tongue for patients with severe OSAHS].

OBJECTIVE: To investigate the therapeutic efficacy of coblation-assisting uvulopalatopharyngoplasty (CAUPPP) combining with coblation-channeling of the tongue (CCT) for patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: A retrospective analysis was made on patients with severe OSAHS treated by CAUPPP combining with CCT. The adult with severe OSAHS were involved in the study and the apnea-hypopnea index (AHI) were beyond 40/h and lowest arterial oxygen saturation (LSaO2) were under or equal to 80%. Surgical approach: The UPPP was performed to decrease the size of soft palate with coblation and coblation-channeling in the soft palate and decrease the size of tongue by CCT. All patients were followed up for 6 to 12 months and underwent polysomnography (PSG). RESULT: Subjective symptoms of patients improved more significantly than that of preoperation. The function of soft palate is normal without significant nasopharyngeal regurgitation. Compared with the preoperative data, AHI values were significantly decreased (P<0.01) and the lowest oxygen saturations increased significantly (P<0.01) and the effective rate was 91.7%. CONCLUSION: There are usually multiple obstruction levels in patients with severe OSAHS and the traditional surgical treatment is not ideal. This study demonstrated that with the assistance of coblation, combining CAUPPP with CCT for patients with severe OSAHS is an effective surgical method. It has less blood loss, minimally invasive, retained the normal function of the soft palate, etc., should be widely applied.

[Comparative analysis of polysomnography and micro-sensitive mattress-sleep monitor used for obstructive sleep apnea hypopnea syndrome].

OBJECTIVE: To assess the efficiency of mattress-type micro sensitive monitor (MMSM) in sleep monitoring. METHODS: Forty patients diagnosed as obstructive sleep apnea-hypopnea syndrome (OSAHS) by polysomnography (PSG) were randomly chosen, then received MMSM examination within 2 - 5 days. The results of both methods were compared, using the respiratory disturbance index, sleep efficiency, and obstructive factors as indicators. RESULTS: All 40 patients were diagnosed as OSAHS, which were consistent with the results of PSG. There was no statistical difference when comparing the apnea hypopnea index (AHI, x(-) ± s, 35.6 ± 21.3 and 37.6 ± 18.8, respectively) and the ratio of rapid eyes movement (REM) stage (15.0 ± 4.5)% and (15.8 ± 6.3)%, respectively (t were 1.867 and 1.014, P > 0.01). Some statistical sense was found when patients'deep sleep, shallow sleep and sleep efficiency were compared (P < 0.01). According to the severity diagnosed by PSG, patients with mild, moderate and severe OSAHS were 11, 7 and 22 cases, respectively, Comparing by MMSM, 2, 19 and 19 cases, respectively. Among seventeen volunteers diagnosed by PSG as normal subjects, 2 of them were diagnosed as mild OSAHS. The sensitivity of MMSM was 100.0% and the specificity was 88.2%. CONCLUSIONS: With regard to the diagnosis of OSAHS, MMSM is well consistent with PSG. The MMSM can be applied clinically as a monitor technique.

[Value of pulse transit time in detecting respiratory drive].

OBJECTIVE: To assess the accuracy of pulse transit time (PTT) in classification of apnea events, and collect data for clinical application reference. METHODS: Thirty-two obstructive sleep apnea-hypopnea syndrome (OSAHS) patients included in the research had Polysomnography (PSG), and 10 305 apnea events were recorded. All the events were analyzed by PTT and esophageal pressure (Pes) respectively. The results were analyzed to assess the accuracy of PTT and compare the accuracy of pulse transit time between REM stage and NREM stage, and analyze the correlation between age, body mass index (BMI), apnea hypopnea index (AHI) and concordance rate in every patient. RESULTS: The total concordance rate between PTT and Pes in classification of apnea was 96.7% (9970/10305). The sensitivities of PTT in detecting central, mixed and obstructive apnea were 88.0%, 91.3% and 97.8% respectively and the specificities were 99.8%, 97.8% and 92.8% respectively. The false determinations of apnea events mainly concentrated on the false determinations between the obstructive and mixed apnea. There was no statistical significant between the accuracy of PTT in different sleep stages. There was a negative relationship between the age, BMI, Lowest SaO2, AHI and the concordance rate. CONCLUSIONS: There was good concordance between PTT and Pes in classification of apnea. PTT had very high sensitivity and specificity in detecting all kinds of apnea. This study showed that PTT can detect respiratory drive noninvasively with high accuracy.
