ABSTRACT
Objective To investigate the effects of three-dimensional titanium mesh repair on cerebral perfusion,intracranial pressure and nerve function after decompression with bone flap.Methods From October 2015 to October 2018,132 hypertensive cerebral hemorrhage patients of bone disc decompression in the Fifth People's Hospital of Jinan were selected and divided into observation group (66 cases) and control group(66 cases) by double blind random method.The observation group received three-dimensional titanium mesh repair at 24 ～ 42 d after bone disc decompression surgery.The control group received three-dimensional titanium mesh repair at 90 ～ 150 d(3 ～ 5 months) after surgery.The changes of operation,cerebral perfusion,intracranial pressure and nerve function were compared between the two groups.Results The operative time,blood loss and free time of the flap in the observation group were (92.5 ± 12.4) min,(354.3 ± 17.5) mL and (13.2 ± 3.1) min,respectively,which were shorter or less than those in the control group [(142.8 ± 15.3) min,(518.3 ± 22.3) mL and (38.3 ± 4.3) min],the differences between the two groups were statistically significant (t=4.745,6.831,4.963,all P ＜ 0.05).After treatment,the abnormal indices of intracranial pressure and cerebral perfusion in the observation group were (0.1 ±0.0) and(0.2 ± 0.1),respectively,which were lower than those in the control group [(0.2 ± 0.1),(0.3 ± 0.1)] (t =3.657,2.579,all P ＜0.05).There were statistically significant differences in neurological deficit scores between the two groups at different time points(all P ＜0.05).The incidence of treatment complications in the observation group was 10.94％ (7/64),which was significantly lower than that in the control group [38.7％ (24/62)] (x2 =14.094,P ＜ 0.05).Conclusion Three-dimensional titanium mesh repair is helpful to shorten the operation time,restore the intracranial pressure on the affected side,improve the abnormal cerebral perfusion,and reduce the neurological damage in patients with hypertensive cerebral hemorrhage.
ABSTRACT
Objective To investigate the therapeutic methods for hypertrophy of nasal tip so as to create an aesthetic shape of nasal tip. Methods The “seagull-wing incision”was used in all patients. According to various nasal tip contours, trimming of soft tissues and reconstruction of alar cartilage were preformed simultaneously. Excessive soft tissue between skin and alar cartilage was removed; after exposing the domal segment of the alar cartilage, cartilage was resected from lateral crus to middle crus with a width of 0.2 cm marginal lateral crus was left. The shape of nasal tip was recontoured by middle crus suture technique. Others deformities of nose were corrected then: 10 patients with flat and low nasal tip were operated for nasal augmentation; 9 patients with thickening nasal wing were operated for thinning rim; 3 patients with wide bases of nasal wing were operated for shortening width through intraoral approach and one patient with broad nasal bone was operated with osteotome, infractured and displaced in the midline. An exteral splint was placed over the tape for 5-7 days postoperatively. Results Since 1995, follow-up for 3 to 24 months showed that 25 cases had achieved satisfactory cosmetic effects without secondary deformity except 3 early cases. Conclusion Trimming of soft tissues and reconstruction of alar cartilage are effective methods for correction of hypertrophy of nasal tip.
ABSTRACT
Objective To investigate the method and influencing factors of laser treatment in the removal of complicated tattoos.Methods 1280 patients with tattoos were treated by Versapulse four wavelength laser system.According to different colors,we selected different energy parameters and wavelength.Results All the 1280 patients got satisfied results after the therapy. The response was mainly related with the composition of their tattoos' color, as well as the proper choosing of laser wavelength and parameter.Conclusions According to feature of different tattoos,selecting reasonable wavelength and therapeutic parameters to treat the complicated tattoos can obtain better efficacy.
