RESUMEN
Packing the nose after septoplasty is common practice. The use of postoperative packing has been proposed to reduce the dead space between the subperichondrial flaps and minimize postoperative complications such as hemorrhage, septal hematoma, and formation of synechiae. Additionally, postoperative packing is thought to stabilize the remaining cartilaginous septum and minimize persistence or recurrence of septal deviation. Despite these theoretic advantages, evidence to support the use of postoperative packing is lacking. Additionally, nasal packing is not an innocuous procedure. The use of nasal packing actually cause these complications such as postop- erative pain, mucosal injury, bleeding, worsening of breathing due to sleep disorders, and postoperative infections. Routine use of anterior nasal packing after septoplasty should be challenged for not presenting proven benefit. As alternatives to traditional packing, septal suturing, septal stapler and fibrin glue have been used recently. The purpose of this article is to summarize the progress of traditional packing to no packing after septoplasty.

BACKGROUND:The auditory ossicle chain reconstruction is stil an important method to treat conductive deafness. Although a great variety of materials have been applied, the blood supply of otosteon after the implantation is ignored. Moreover, there is no real bone formed. OBJECTIVE:To observe the angiogenesis of vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold which is implanted into the otocyst of guinea pig. METHODS:Total y 60 guinea pigs were randomly divided into experimental group (vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold), col agen I control group (col agen I modifiedβ-tricalcium phosphate porous scaffold) and blank control group (β-tricalcium phosphate porous scaffold). The guinea pigs were executed under anesthesia at weeks 1, 2, 3, 4 respectively. The surface of scaffolds was observed by scanning electron microscopy. The angiogenesis of scaffolds were observed by hematoxylin-eosin staining and CD34 immunohistochemistry staining, and then the microvascular density was counted. The osteogenesis of the scaffolds was observed by toluidine blue staining. RESULTS AND CONCLUSION:Endothelial cel proliferation and lumen formation could be observed after 1 week in the experimental group, and the angiogenesis reach the peak after 3 weeks with traffic branches formedbetween micropores. In the other two groups, the lumen formed at 2 weeks but no traffic branches were visible. The sprouting of new blood vessels in the pores were observed more in the experimental group than the other two groups (P<0.05). The adherence and proliferation of cel s could be examined in the surface and pores of the scaffold by scanning electron microscope. After 4 weeks, the osteogenesis could be observed by toluidine blue staining, especial y in the experimental group. These findings suggest that the vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold can realize an effective vascularization in the environment of guinea pigs’ middle ear. What’s more, the scaffold also can promote bone formation.
RESUMEN
OBJECTIVE@#To investigate the clinical features and treatment options of ossifying fibroma of paranasal sinuses.@*METHOD@#A retrospective evaluation of twenty-three patients with ossifying fibroma of paranasal sinuses was presented. The choice of surgical operations on ossifying fibroma of paranasal sinuses was mainly decided by the location and area of ossifying fibroma. Radical operations were performed in twenty-one patients, ten of them through a lateral rhinotomy approach, eight through nasal endoscopic approach, four through Caldwell-Luc approach, one through coronal approach.@*RESULT@#Two patients were performed partial resection by nasal endoscopic surgery. Diagnoses of all cases were confirmed by pathology. All patients outcomes were successful, no serious complication from the surgical technique occurred. Twenty cases were followed-up for six months to nineteen years. Two patients recurred.@*CONCLUSION@#Earlier diagnosis, CT scan, proper surgery, and radical resection are the keys to the treatment of ossifying fibroma of paranasal sinuses.

A male patient of 71 years old was admitted due to repeated hoarseness for two years which got worse accompanied with dyspnea so that to receive tracheotomy in another hospital more than one month ago. The two vocal cord biopsies carried out in the other hospital before showed vocal keratosis and squamous cell hyperplasia. Electronic laryngoscopy result showed normal epiglottis. a lot of saliva at hypopharynx, and rough arytenoid mucosa. The supraglottic area was remarkably swollen and the glottal area can not be observed clearly. The biopsy of throat was unable to conduct. Barium swallow examination revealed no obvious space-occupying lesion in piri form fossa or esophagus. Larynx CT scan showed a space-occupying lesion in the laryngeal cavity on the right side of the neck involving the thyroid cartilage. The patient was finally treated by total laryngectomy. cervical infected tissue resection. grafting transposition with pectoralis major flap and tracheostomy. The postoperative pathology showed laryngeal verrucous carcinoma.

OBJECTIVE@#To evaluate the effect of the combined application of dissociate skin flap and vacuum sealing drainage (VSD) for the repairing for defect after surgical management of huge neck neoplasms.@*METHOD@#Nineteen patients with huge neck malignant tumor involving the skin of the neck were given radical operation, making use of VSD covering the wound surface. After giving 6.65-7.98 mm Hg continuous negative pressure drainage for 72 h, the patients turned to be treated by intermittent negative pressure therapy with 2 min free interval after each treatment period for 5 min. After dismantling the VSD at 7th to 10th day postoperatively, the good wounds covered by granulation tissue were treated by the skin graft operation with dissociate skin flap from thighs; as for the wounds of which the granulation tissue didn't grow well and important cervical tissues was not fully covered by the granulation tissue, VSD was applied again for 1 week, followed by the skin graft operation.@*RESULT@#Nineteen patients have received a total of 23 times of VSD wound treatment, one-stage operation time was significantly shortened. The granulation tissue grew faster on the wound after VSD treatment, and the important cervical tissues such as great vessels could be well covered. The infection and tumor recurrence were observed directly after dismantling the VSD. The skin graft transplantation would be performed after 1-3 weeks.@*CONCLUSION@#The treatment by vacuum sealing drainage combined with skin graft for surgical wounds of huge neck tumor postoperatively has the advantages of simple operation, little injury and promotion of the wound healing, which is an effective way for treatment of neck skin defect by surgical operation for the huge tumor.
