Objective To explore better approach of resecting tumoraround the anterior skull base and reconstructing the anterior skull base.Methods In November 2004, a 49-years-old male patient with intracranial recrudescent adenoid cystic carcinoma in the anterior cranial fossa was treated using modified transcranial approach. Neurosurgeon and rhinolaryngologist cooperated to excise the tumour completely, and to reconstruct anterior skull base using the pedicle periosteum temproal musculofascial flap(15 cm×10 cm) andthe pedicle flap of aponeurosis of occipitofron talis muscle and muscular fasciae（10 cm×6 cm）.Results After operation, the wound healed by first intention. Complication, such as infection and cerebrospinal rhinorrhea, did not occur. The patient was discharged 10 days after operation, and was followed up for 8 months, no local recurrence were investigated and no scar formed over the face.Conclusion The modified transcranial approachis a relatively novel exposure that enables the skilled cranial base surgeon tosafely resect many malignant lesions previously and to reconstruct the defect of anterior skull base together.
Facial filling injection is one of the technologies to achieve facial rejuvenation in a non-surgical way. With the application of emerging cosmetic filler preparations and the development of new technologies, there are more and more options to achieve facial rejuvenation. Complications may result from the use of new materials whose safety has not been proven in studies. This article describes common facial filler choices, facial risk areas and vascular complications, and discusses how to improve the safety of facial injections. The purpose is to enable operators to fully understand the facial risk area, select the appropriate filling injection, and be able to identify the symptoms of vascular complications as early as possible, thereby improving the safety of facial filling injection.
Objective To investigate the procedures and effectiveness of platysma scar flap for reconstructing mentocervical appearance in patients with mentocervical cicatricial contracture deformity. Methods Between April 2004 and August 2011, 26 patients with mentocervical cicatricial contracture deformities were admitted. There were 15 males and 11 females, aged 12-31 years (mean, 18 years). The causes included scald injury in 19 cases and flame injury in 7 cases, including 23 cases of deep second degree burn and 3 cases of third degree burn. The time between injury and scar formation was 6-27 months (mean, 10 months). The mentocervical angle was (117.10 ± 14.46)°, and the cervicomental angle was (143.38 ± 15.68)°. The platysma scar flap transfer (8 cm × 7 cm to 10 cm × 8 cm in size) and skin grafting were performed to reconstruct mentocervical appearance. Results The flap and skin graft all survived and the incisions healed by first intention. All the patients were followed up 6 months-3 years (mean, 16 months). The mentocervical and cervicomental angles were significantly reduced to (89.31 ± 6.30)° and (117.83 ± 10.65)° respectively at 2 weeks after operation (P lt; 0.05), showing no significant difference when compared with normal mentocervical angle (90°) and cervicomental angle (120°) (P gt; 0.05). The satisfactory results of the mentocervical appearance and cervical extension function were obtained in 21 patients whose mentocervical and cervicomental angles were restored to normal. Conclusion Platysma scar flap transfer is an effective method to reconstruct mentocervical appearance and reduce mentocervical and cervicomental angles in patients with mentocervical cicatricial contracture deformity.
目的：探討N-乙酰半胱氨酸對燙傷大鼠炎癥反應的影響。方法：48只Wistar大鼠隨機分為實驗組和對照組，制作燙傷休克模型，傷后1小時腹腔注射生理鹽水40ml/kg抗休克，實驗組于抗休克鹽水中加入N-乙酰半胱氨酸160mg/kg，其后足量飲水。分別于燙傷前、燙傷后8小時、16小時及24小時，處死每組各6只大鼠并立即心臟取血，采用ELISA法檢測大鼠血清中TNF-a含量，于創周近頭側 0.5cm處取皮膚全層組織，在顯微鏡下進行中性粒細胞計數。 結果：兩組大鼠血清TNF-a含量傷后顯著升高，8小時達到高峰，其后逐漸下降，兩組各時點比較有顯著差異（P＜0.05）；創周組織中性粒細胞計數于傷后隨時間延長逐漸增多，兩組比較有顯著性差異（P＜0.05）。 結論：N-乙酰半胱氨酸有助于降低燙傷大鼠血漿中TNF-a含量及創周組織中的中性粒細胞計數量，減輕燙傷大鼠的全身及局部炎癥反應。
Objective To observe the effects of operation with large-dose of RoferonA for cutaneous malignant melanoma. Methods From January 1998 to December 2005, thirtythree patients with cutaneous malignant melanoma were treated. There were 20 males and 13 females, aging 17-79 years. The disease course was 2 months to 7 years. In 33 patients, nine patients identified as clinical-stage Ⅰ received singly enlargedresection to the primary lesion and performed split-thickness skin graft dermoplasty or adjacent skin flap repair; twenty-three patients identified as clinicalstage Ⅱ received enlargedresection to the primarylesion and performed proximal lymphaden scavenge as well as received split-thickness skin graft dermoplasty; and one patient identified as clinical-stage Ⅲ received palliative resection to the primary lesion. All patients received large dose of Roferon-A after operation. Results There are no recidivation in the 9 patients of clinicalstage Ⅰ. There are 1 recidivation and 1 quit in all the 23 patientsof clinicalstage Ⅱ. One patient of clinicalstage Ⅲ died after 18 months of operation. Conclusion The operation combined with large-dose of RoferonA after operation was a more effective way to treat cutaneous malignant melanoma.
Hemifacial microsomia (HFM) is a developmental hypoplasia of one side of face and ear due to congenital hypoplasia. At present, the causes of HFM have not been completely clarified, the classification methods are diverse, and the diagnosis and treatment methods are complex. Through reviewing the relevant study on the treatment of HFM domestic and overseas in recent years, the possible etiology and corresponding clinical manifestations of the disease are analyzed, and the existing clinical classification methods, treatment strategies and latest research results are summarized.
ObjectiveTo discuss a reliable and aesthetic surgery method for the reconstruction of large defects on the top of nose after giant nevi resection. MethodsBetween January 2011 and June 2015, 46 cases of nasal tip defects caused by giant nevi resection were treated. Of 46 cases, 22 were male and 24 were female, aged 15-59 years (median, 28 years). The right ala nasi was involved in 28 cases, the apex nasi in 8 cases, and the left ala nasi in 10 cases. The diameters of nevi were from 8 to 12 mm (mean, 9.75 mm); no alar cartilage was invaded. Hair growth was seen in 14 cases. The duration of nasal nevi was from 3 years to 49 years (mean, 9.8 years). There were 9 recurrent patients who received laser therapy before surgery. The defects sizes after excision were from 10 mm×10 mm to 14 mm×14 mm. The bilobed flaps were used for one-stage reconstruction, which sizes were from 11 mm×10 mm to 15 mm×14 mm and from 10 mm×10 mm to 15 mm×14 mm. ResultsAll the incisions healed by first intention, and the flaps survived. No complication of intracranial hemorrhage or subdural hemorrhage occurred. The patients were followed up 6 months to 5 years (mean, 18 months). The appearance of nasal tip and nasolabial fold was satisfactory, and no recurrence was found during follow-up. ConclusionOne-stage bilobed flap reconstruction for nasal tip defects after giant nevus resection is one of the effective, safe, and aesthetic surgery methods.
