Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2013;27(19):1092-1094
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.

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.

OBJECTIVE:
To Summary the experience of surgical treatment for many times in 1 case of maxillofacial huge dermatofibrosarcoma protuberans.
METHOD:
The patient was diagnosed with dermatofibrosarcoma protuberans according to the pathological examination. From 2004 to 2011, the patient underwent extensive surgical resection, Mohs micrographic surgery(MMS) and free flap grafting method as surgical treatment for many times, and was closely followed-up after operation.
RESULT:
The tumor was completely removed in each operation, with wound skin graft survived. But relapse occured repeatedly, recurrence interval was from 7 months up to five years and eight months,recurrence interval gradually extended, all of the recurrence occurred at Mohs microsurgery cut edge.
CONCLUSION
Eexpanded resection is the preferred treatment for the early stage maxillofacial huge dermatofibrosarcoma protuberans. For advanced stage tumor, expanded resection should be combined with Mohs microsurgery. Free flap grafting was suggested in primary repair insteading of myocutaneous flap. At the same time, postoperative assistant radiotherapy, strengthen follow-up and early intervention were suggested.

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.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2012;26(16):739-746
OBJECTIVE:
To investigate the expression and concentration of lipopolysaccharide (LPS) and matrix metalloproteinase-9 (MMP-9) in middle ear cholesteatoma and discuss their relations.
METHOD:
Twenty-nine cases of middle ear cholesteatoma tissue, 18 cases of external auditory canal tissue were detected by limulus amebocyte lysate assay (LAL-assay), and expression of MMP-9 protein in formalin-fixed, paraffin-embedded tissues was detected by immunohistochemical method.
RESULT:
The concentrations of LPS in cholesteatoma were higher than that in external auditory canal tissues. In group of cholesteatoma: M = 0.739 0, IQR = 0.6203, and in group of external auditory canal tissues: M = -0.2538, IQR = 1.1692 (P < 0.01). In cholesteatoma groups, in extensive type: M = 0.8403, IQR = 0.5254; in localized type: M = 0.4048, IQR = 0.6139, the concentrations of LPS were higher in extensive cholesteatoma in comparison with localized cholesteatoma (P < 00.05). In cholesteatoma epithelium samples, MMP-9 were 79.3%. Compared with external auditory canal epithelium, the expression of MMP-9 was higher in middle ear cholesteatoma epithelium (P < 0.05). There was no significant difference in the expression of MMP-9 between two types of cholesteatoma epithelium (P > 0.05). LPS, MMP-9 weren't significantly correlated by Spearman test.
CONCLUSION
LPS was responsible for middle ear cholesteatoma and its related bone erosion. MMP-9 was related to the development of middle ear cholesteatoma. There's no correlation between LPS and MMP-9.
