Objective To study the reason of concurrent styloid process syndrome after tonsillectomy and the clinical effect of styloidectomy.Methods Twelve patients with styloid process syndrome after tonsillectomy receiving styloidectomy were retrospectively analyzed.The clinical effect was evaluated.Results Ten patients were operated on unilateral styloid,two patient was operated on bilateral styloid.All patients were followed -up for 6 months to 5 years after operation.All of them were cured.Conclusion The mechanism of styloid process syndrome after tonsillectomy might be related to the stimulation of scar formation in the tonsillar fossa.Styloidectomy ia an effective method of treatment.

Objective: To explore the safety and efficacy of dezocine preemptive analgesia in the reconstruction of nasal bone fracture. Methods: From September 2016 to May 2018, 63 patients with simple nasal bone fracture admitted to the 908th Hospital of PLA Joint Logistics Support Force were selected in the study.The patients were divided into two groups by random number table method: dezocine group(n=32) and control group(n=31). The dezocine group was injected with dezocine before surgery, while the control group was injected with 0.9% sodium chloride solution.The differences of MAP, HR, SpO₂ at different time points between the two groups were observed.And the difference of VAS/RSS during operation and 2 hours after surgery were also observed. Results: There were no statistically significant differences in MAP, HR and SpO₂ between the two groups at different time points(10 min before and 10 min after intramuscular injection) (all P>0.05). During operation and 20 min after operation, the MAP values of the control group were (110.1±16.38)mmHg and (105.28±14.81)mmHg, respectively, which were higher than those of the dezocine group [(102.35±14.25)mmHg and (101.25±13.12)mmHg)], the differences were statistically significant(t=2.259, 2.153, all P<0.05). There were no statistically significant difference in HR between the two groups at 10 min before and 10 min after intramuscular injection(all P>0.05). The HR in the control group during operation and at 20min after operation were (90.81±19.52)times/min, (77.25±18.25)times/min, respectively, which were faster than those in the dezocine group [(85.16±17.25)times/min, (71.36±16.15)times/min], the differences were statistically significant(t=2.074, 2.047, all P<0.05). There were no statistically significant differences in SpO₂ between the two groups at different time points(all P>0.05). In the surgery, the RSS score of dezocine group[(4.3±0.6)points] was better than that in control group[(2.1±0.4)points], the difference was statistically significant(t=17.008, P<0.05). The VAS scores in the control group during operation and 20 min after operation were (2.3±0.5)points, (1.5±0.8)points, respectively, , which were lower than those in the control group [(5.5±0.7)points, (2.1±0.6)points](t=20.572, 3.277, all P<0.05). Conclusion Application of dezocine preemptive analgesia in the reconstruction of nasal bone fracture is effective and safe, the hemodynamics is stable and the analgesic effect is definite in the surgery.
