目的 研究学龄前儿童鼓室图测试的正常值及其影响因素。 方法 2005年1月-2005年3月，对132名（223耳）学龄前儿童（4~6岁）进行单频率单成分鼓室图测试（Y-226），获取峰值处补偿静态声导纳（Ytm）、外耳道等效容积（Vea）、鼓室测量宽度（TW）和峰值处鼓室压（TPP）等数据，对不同年龄、性别及与国外研究的结果进行比较。 结果 不同年龄间只有TW存在差别；男童Vea大于女童，其他几项指标没有性别差异；Ytm、Vea、TW、TPP与国外正常值范围相比，有统计学意义（Plt;0.05）。 结论 单频率单成分鼓室图测试结果与国外研究相比有统计学意义，提示必须建立国人自己的正常鼓室图参考值标准。
目的:〖HT5”SS〗探讨原发性喉部恶性淋巴瘤的临床诊断治疗方案,提出早期诊断此类疾病的合理有效方法。〖HTH〗方法:〖HTSS〗对临床29例病理确诊原发于喉部的恶性淋巴瘤患者临床资料进行回顾性分析,并且与同时期原发于鼻腔鼻窦的恶性淋巴瘤患者临床资料对比分析。〖HTH〗结果:〖HTSS〗29例原发性喉部恶性淋巴瘤病例均进行了手术干预,在术中或术后病理明确诊断后进行了后继的放射及化学综合治疗,病员的平均住院日较原发于鼻腔鼻窦的恶性淋巴瘤患者为长。〖HTH〗结论:〖HTSS〗本病的合理有效的诊断治疗,需早期明确诊断和判定病变累及范围,在尽可能早期获取病理诊断基础上,提高对喉部影像学的认识,对于此类疾病及时制订合理有效的治疗方案,获得更好的预后有着重要意义。
Objective To explore the appl ication of submental island flaps in repairing pharyngeal fistula after total laryngectomy. Methods From July 2002 to February 2006, 9 cases of concomitant pharyngeal fistula (including 7 cases of laryngeal carcinoma and 2 cases of hypopharyngeal neoplasms) were repaired with submental island flaps after total laryngectomy. All patients were male and their ages were 52-71 years (mean 61.8 years). Pharyngeal fistula occurred 5-62 days (mean 14.7 days) after total laryngectomy. The diameter of medial pharyngeal fistula ranged from 1.9 cm to 4.1 cm. All patients failed to respond to conservative therapy for 25-46 days. The size of submental island flap was 2.5 cm × 2.4 cm to 4.6 cm × 4.0 cm. After the pharyngeal fistula were repaired with submental flap, the donor site were sutured directly. Results All of the nine submental flaps were survived and no local necrosis or wound infection occurred. Incision at donor site healed by first intention and no obvious scar formed. Fistula occurred 10 days after operation and was cured after symptomatic treatment in one patient who received radiotherapy before operation; other patients achieved the satisfactory results of one-stage repair. The gastric tube was pulled out 14 to 22 days after operation, all of the patients have no sense of swallow obstruction. Nine patients were followed up for 10-38 months (mean 27 months). The ppearance of neck was satisfactory. Conclusion Because of its short distance, abundant blood supply, convenient operation and minimal donor-site morbidity, the submental island flap is a good alternative mthod in repairing pharyngeal fistula.
This article carries out a comprehensive review on otorhinolaryngologic-head and neck informatics, focusing on the definition, content and characteristics of otorhinolaryngologic informatics as well as the application of computer, communication and information technology in otorhinolaryngology-head and neck surgery. Otorhinolaryngologic informatics is the future development direction of otorhinolaryngology-head and neck surgery.
