Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2010;(1):8-10,15. doi:10.3969/j.issn.1001-1781.2010.01.003

Objective:To analyze the result of smooth pursuit test(SPT) in unilateral vestibular peripheral vertigo and investigate its influencing factors.Method:Smooth pursuit test (SPT) and spontaneous nystagmus (SN)were examined in one hundred and eighty-five patients with unilateral peripheral vertigo(case group) and 51 normal persons(control group) by Video-Nystagmography (Synapsys, France), and the gain of SPT and SN were selected as the observation parameters in order to analyze the waveform and gain of SPT and the relativity between SN and the gain of SPT.Result:Of the 185 patients, 105(56.8%),72(38.9%) and 8(4.3%) cases producedⅠ,Ⅱ and Ⅲ waveforms respectively. Of these patients, 58(31.4%) demonstrated SN and none had Ⅳ waveform. While of 51 normal persons, 38(74.5%), 13(25.5%) persons producedⅠand Ⅱwaveforms repectively and there were no Ⅲ, Ⅳ waveforms or SN. There was statistical significance between the stong and weak gain of SPT in these two groups. Weak gain was significantly different between two groups. The stong and weak gain of SPT in case group were 0.86±0.06,0.80±0.06; 0.78±0.09, 0.65±0.1; 0.68±0.13, 0.45±0.12. The relativity between SN and the gain of SPT was positive when they had same direction(r_s=-0.63,P＜0.05)and negative when opposite (r_s=0.34,P＜0.05).Conclusion:Ⅰ,Ⅱ,Ⅲ three waveforms of SPT could appear in unilateral vestibular peripheral vertigo and the corresponding gains are gradually decreasing.SN is the influencing factor of SPT.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2009;(18):828-831. doi:10.3969/j.issn.1001-1781.2009.18.005

Objective:To investigate the recurrence of the neck and survival incidence of clinically possible pos-itive lateral cervical nodes in patients with well-differentiated papillary thyroid cancer and the essentiality of the performation of modified radical neck dissection. Method: Retrospective datum of 267 cases of papillary thyroid car-cinoma were collected and ananlyzed. They were divided into two groups with time; selective neck dissection with VI area was performed in 151 cases of group A and selective neck dissection was performed without VI area in 116 cased of group B. They were received the same treatment in the thyroid-total thyroidectomy on initial part and subtotal thyrodectomy on the other, and total thyroidectomy on both parts if both were invated. Incidence of posi-tive lateral cerivcal nodes of VI area in group A and the recurrence in the neck and survival incidence in groups B were analyzed. Result: Fiftynine patients in group A were treated with the modified radical neck dissection, and 22 patients of them were found metastasis in lateral cervical nodes with Ⅵ area. The other 92 patients were treated with neck dissection of Ⅱ,Ⅲ,Ⅳ,Ⅵ VI area, and 31 patients weren't metastasis, 33 patients were metastasis in both Ⅵ area and the others(35.8%), 17 patients were metastasis only in Ⅵ area(18.4%), 11 patients weren't metastasis only in Ⅵ area(11.9%). Thus, the incident of metastasis in Ⅵ area was 47.70% in group A(72/151). 47 patients in group B had metastasis in lateral cervical nodes though without performing VI area neck dissection (40.5%), and the survival rate of 5 years was 99.3%. The recurrence rate in the neck of group two was 6.0% (7/116). The metastasis rate of neck lymph node was higher in group A (54.9%) than group B(40.5%). Conclu-sion : Pretracheal and peripheral recurrent nerve lymph node are very susceptible to the metastasis of well-differenti-ated papillary thyroid cancer. The neck dissection of VI area could be performed as routine.

Objective:To investigate the effect of the musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum on the reconstruction of extensiveness laryngotracheal defect. Method: Retrospectively studied 49 patients, who admited in our department from 1996 to 2005 years for severe laryngotracheal defect. There were 28 males and 21 females aged from 15 to 69 years old (mean age was 47 years old). The causes of laryngotracheal defect were laryngotracheal stenosis(31 cases) and surgery for thyroid carcinoma invading trachea (18 cases). All of 49 cases were treated with the graft of musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum and placed a silicon T-tube stenting for 3 to 6 months. Result; All of 49 cases were successfully decannulated with recuperative normal airway patency and effective phonation. The follow up ranged from 2 to 10 years, and the effect of operation was steady. Conclusion:The musculo-periosteum flap of the sternocleidomastoideus with clavicular periosteum is an ideal graft for the reconstruction of cervical extensiveness tracheal defect.

Objective:To study the clinical manifestations and treatment of the primary cervical tracheal malig-nant tumor of children. Method:Five cases diagnosed as primary tracheal malignant tumor with fibrolaryngoscopy, CT scan and pathology were retrospectively analyzed and reviewed. Extraction of malignant tumor was performed with tracheoscope and nasal endoscope after emergent tracheotomy below the tumor in 4 cases, and tracheotomy after intubation in 1 case. After operation, 4 children received radiotherapy, and 1 case received laser therapy add radiotherapy. Result:Five cases were followed up for three to eight years, and no recurrence was found. Conclu-sion: There was no specific manifestation in early tracheal malignant tumor, but it was critical and emergent during symptoms appear. Imaging examination was a very invaluable dignosis method. Optimal and effective therapeutic protocol is tracheostomy under local anesthesia to keep upper airway patency followed by surgical extraction and radiotherapy. It was not appropriate to have tracheal wall resection for children.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2009;(15):693-696. doi:10.3969/j.issn.1001-1781.2009.15.008

Objective: To discuss the diagnosis and treatment of infantile congenital subglottic hemangioma. Method:Nine patients with recurrent stridor,feeding difficulties and laryngeal obstruction were diagnosed as con-genital subglottic hemangioma with bronchia endoscopy. The lesions were unilateral in 7 cases and bilateral in 2 ca-ses. Eight cases were treated by intralesional Pingyangmycin injection after tracheotomy. Patients were discharged with metal trachea and were followed up endoscopically 2 weeks thereafter. A second treatment would be required if the tumor reduced in size but not disappeared completely. Plugging tubes and extubation would be done when the tumor disappeared completely. One case with unilateral lesion underwent power-assisted tumor resection with-out tracheotomy. Result: Hemangioma vanished completely in 6 patients with unilateral subglottic hemangioma who were treated with single stage procedure. Tumor size was found reduced significantly after one procedure and van-ished completely after a second procedure in 2 cases with bilateral subglottic hemangioma. All of the 8 cases were extubated successfully. The patient recovered thoroughly in two weeks after power-assisted tumor resection. Con-clusion: Intralesional Pingyangmycin injection after tracheotomy can relief the airway obstruction quickly, shorten the nature course of hemangioma, shorten the period of wearing trachea, has no complication such as subglottic stenosis and is thought to be a safe and effective therapy for large size hemangioma. Power-assisted tumor resec-tion under good total anesthesia without tracheotomy combined with well hemostasis is effective, less injure, and suitable for small size hemangioma.

He YU ; Xiaotian LI ; Yan WANG ; Huaian YANG ; Xing GUO ; Zimin PAN ; Xuejun JIANG

Journal of Clinical Otorhinolaryngology Head and Neck Surgery.2009;(15):688-689. doi:10.3969/j.issn.1001-1781.2009.15.006

Objective: To study the clinic and pathological features of leukoplakia of the larynx, and reduce canceration rate. Method: Seventy-four postoperative patients of leukoplakia of the larynx were followed up for four years by telephone or clinic service. Result: None of eighteen cases of pure leukoplakia was recurrence. Fifty-six ca-ses were leukoplakia with epithelial dysplasia histologically. Seven out of fifty-six postoperative cases occurred hoarseness; three out of fifty-six postoperative cases recured, and accepted twice or more operations successively; three out of fifty-six postoperative cases occurred canceration. Conclusion:Operation is the main means for the treatment of leukoplakia of the larynx, and the effect is comparatively well. The patients with histological epitheli-al dysplasia should be pay great attention because of their higher canceration rate, and enlarged operation ranges appropriately with the patient consent could effectually prevent recurrence or canceration during the early lesions. Close observation is important for these patients.
