[Discussion on the micro-plastic operative treatment of nasal-septum deviation combined with crooked nose].

OBJECTIVES: To explore the micro-plastic operative treatment of deviated nose combined with nasal septum deviation. METHODS: We designed the incision at the caudal side of the nasal septum. The three-line reduction method for correcting nasal septum deviation was performed. The connection of the caudal nasal septum and the anterior nasal spine was reposited. The micro-plastic surgery with fixed suture was used to correct the deviated nose. RESULTS: After the surgery, the nasal septum deviation was corrected, whose nasal function and symptoms improved without nasal adhesion, nasal septum perforation or other complications. Meanwhile, the nasal tips were in the middle place and nasal dorsums were straight. The aesthetic outcome was satisfactory. CONCLUSIONS: Compared to the traditional orthopedic technique, the micro-shaping technique can be used for the homochromous operation of crooked nose combined with nasal septum deviation with less injury and lower risk. We suggest this micro-shaping technique be used in a rational way.

[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.

[Endoscopic surgery using the low-temperature plasma radiofrequency for nasopharyngeal angiofibroma].

OBJECTIVE: To evaluate the feasibility of endoscopic surgery using the low-temperature plasma radiofrequency for nasopharyngeal angiofibroma (NA). METHODS: The clinical data of 4 patients treated between December 2005 and August 2009 were retrospectively analyzed. The tumor in one patient was at stage I and three patients were at stage II, all these patients were treated by endoscopic surgery using the low-temperature plasma radiofrequency under controlled hypotension anesthesia. Preoperative angiography and embolisation were underwent in all patients. Bipolar coagulation was used to help hemostasis during operation. RESULTS: The tumor in all 4 patients was completely removed. The operation time was 60, 80, 110, 90 min respectively. The blood loss was 250, 250, 320, 280 ml respectively. Neither blood transfusion nor complications were encountered perioperatively. Follow-up ranged from 6 months to 4 years, none of the patients recurred. CONCLUSIONS: Endoscopic surgery using low-temperature plasma radiofrequency for nasopharyngeal angiofibroma has many advantages such as less bleeding and total tumor removal. It is a minimally invasive surgical method for nasopharyngeal angiofibroma.

[Effect of snoring on facial growth in children].

OBJECTIVE: To evaluate the effect of snoring on facial growth in children and the changes after surgery. METHODS: Observations on facial growth were taken by X-ray 1.5 - 2 years before and after surgery on 40 children snorers aged between 2 - 5 years old, whose tonsils and (or) adenoids were completely removed. The data collected before surgery in the 2 - 3 years old snorers and in the 4 - 5 years old ones were compared with the data from healthy children at the same age respectively. RESULTS: The comparison of data between 21 children snorers aged from 2 - 3 and 17 healthy children of the same ages showed that there was no significant difference in the diameter of pharyngeal cavity at tongue base (PAS), the diameter of nasopharyngeal cavity (UPW-PNS) and the angle between mandibular plane and frankfort horizontal plane (FH-MP) within 2 - 3 years group by statistically (P > 0.05). There is no significance in UPW-PNS and FH-MP angle within 4 - 5 years group by statistics (P > 0.05). Others results is significance in all groups (P < 0.05 or P < 0.01). There was no significant difference in all groups expect Y-axis Angle 1.5 - 2 years after surgery (P > 0.05). CONCLUSIONS: Abnormal facial growth was caused by the consistent force from the changed way of breathing due to the increasing narrowness of upper airway obstruction and the long-existing obstructive sleep. Surgery done as soon as possible is helpful to reduce the force caused by the obstruction and helpful to the normal facial growth.
