Postoperative care following endoscopic sinus surgery

Postoperative care is very important in the global management of the patient undergoing ESS. Postoperative tamponnade, packing, splinting or stenting is advocated by many surgeons, but its clinical beneficial effects have not clearly been demonstrated. Postoperative rinsing/washing of the surgical cavity offers advantages in healing: high volume, low pressure is to be preferred. Suction cleaning is advocated on a weekly basis starting one week after ESS and continues until secretions, blood, crusts have disappeared. Topical medications have not been the subject of randomized clinical trials. Of the various classes of systemic (oral) medications, only steroids resulted in better short term outcome when using higher doses compared to lower doses. Antibiotics have not shown clinical effects and should not routinely be given.

CT扫描对前筛窦及其毗邻结构的研究

将40具完整成人尸头进行冠状位及横断位CT扫描，其中部分尸头还运用横断位CT扫描重建矢状位CT扫描，对前筛窦及其毗邻结构进行观察。结果示：根据CT扫描，可将前筛窦气房分为4组：即漏斗前筛房（出现率87．5％）、漏斗外气房（出现率82．7％）、漏斗后气房（出现率86．3％）、筛泡筛房（出现率100．0％）；同时又可将前筛窦分为筛内型（出现率71．2％）和筛外型（出现率28．8％）。表明CT扫描能充分显示前筛窦气房的气化变异及其邻近结构的影像学特征。这对于提高鼻内窥镜手术的疗效，减少严重并发症的发生，具有重要的指导意义。     

Pre-vertebral surgical emphysema following functional endoscopic sinus surgery

Functional endoscopic sinus surgery (FESS) is a widely practiced technique in the UK. This procedure has variable complication rates and can have some serious consequences. We present a case of surgical emphysema of the neck, face and the pre-vertebral space following FESS. Emphysema of the face and neck has been previously reported. However, to our knowledge, emphysema of the pre-vertebral space following FESS has not been documented. Pre-vertebral emphysema following FESS is an unusual and potentially serious complication.     

Clinical analysis of delayed epistaxis following endoscopic sinus surgery

ObjectiveTo investigate the clinical characteristics and treatment methods associated with delayed epistaxis following endoscopic sinus surgery.MethodsThe clinical data of 46 patients with delayed epistaxis following endoscopic sinus surgery were retrospectively analyzed. To explore the clinical features, pathogenesis, and treatment plan for delayed epistaxis, the postoperative bleeding time, bleeding inducements, systemic complications, surgical approach, the hemorrhage locations and responsible vessels, and treatment methods were analyzed.ResultsThe average bleeding time was 16.34 ± 9.05 days after the operation, and 76.6% of the cases occurred 6–20 days after the operation. Sphenopalatal artery hemorrhage accounted for 69.6% (32/46), the most common of which was a posterior nasal septal artery hemorrhage (17/32). A total of 45 patients received endoscopic low-temperature plasma hemostasis following ineffective nasal packing, and no rebleeding in the ipsilateral nasal cavity was observed during the postoperative follow-up for 3 to 6 months.ConclusionsThe peak of hemorrhaging in delayed epistaxis following endoscopic sinus surgery occurred at 6–20 days post-operatively. Bleeding of the posterior nasal septal artery from the sphenopalatine artery was the most common. Surgical methods were closely related to delayed postoperative hemorrhage. Treatment with low temperature plasma hemostasis under nasal endoscope was found to be effective.

目的 前瞻性比较新型鼻腔填塞材料Rhino凝胶与传统填塞物用于内镜鼻窦手术后填塞的效果.方法 对双侧病变基本对称,手术范围基本相同的24例慢性鼻窦炎患者行内镜鼻窦手术,术后右侧鼻腔以Rhino凝胶填塞(观察组),左侧鼻腔以藻酸钙+油纱条填塞(对照组).术后1日抽取对照侧填充物,观察侧凝胶保留至术后1周第1次内镜复查时清理,鼻腔冲洗、鼻喷糖皮质激素等其他局部处理双侧鼻腔相同.采用视觉模拟量表(visual analog scale,VAS)记录两侧鼻腔术后当天(填塞期)、术后第1天(抽取左侧填充物时)、术后第2天(抽取左侧填充物后)患者鼻痛、鼻堵程度,分泌物、渗血、流泪量,以及术后内镜复查术腔恢复情况(干痂、分泌物、反应膜、黏膜水肿、囊泡、窦口阻塞),并对两组上述11项观察项目评分和上皮化时间进行比较.结果 苏醒时因血压过高,凝胶侧鼻腔出血改用纱条填塞1例;外地患者失访2例.余21例完成2～20个月的随访.术后当天、术后第1天鼻痛,术后当天流泪评分,Rhino组<对照组(Z值分别为-3.575、-3.546、-2.736,P值均<0.05);术后第1天渗血评分,Rhino组<对照组(Z=-3.075,P<0.05);术后1周术腔干痂评分,Rhino组<对照组(Z=-2.103,P<0.05);其余各项评分差异无统计学意义;凝胶侧术腔平均上皮化时间为(10.7±2.6)周,对照侧为(10.6±2.9)周,两组差异无统计学意义(t=-0.146,P=0.886).结论 Rhino凝胶可减轻患者鼻腔填塞期的不适,并可避免专门撤除填充物造成的痛苦和出血,较传统方法有明显的优越性.在促进术腔恢复方面与传统方式相当.     

Impact of residual ethmoid cells on postoperative course after endoscopic sinus surgery for chronic rhinosinusitis

Objective

Endoscopic sinus surgery (ESS) is a worldwide standard surgical procedure for chronic rhinosinusitis (CRS). Residual ethmoid cells (RECs), which result from failure to completely remove them, have been thought to be a cause of recurrence of CRS. Our objective was to investigate the relationship between the REC score and post ESS recurrence of CRS.

Methods

From January 2002 through December 2003, a total of 138 consecutive CRS patients (86 men and 52 women; mean age: 44 years) underwent ESS at the Department of Otorhinolaryngology, Ota General Hospital. CT was performed at 6 or more months post ESS for all patients. The left and right ethmoid sinuses were each divided into superior-anterior, inferior-anterior and posterior parts. The extent of RECs in each part was assessed using a 3-grade scoring system. The outcome of CRS was classified into a satisfactory outcome group and a poor outcome group based on the improvement rate determined from the pre ESS and post ESS CT image findings. The two groups were then compared for the age, gender, presence/absence of nasal polyps, presence/absence of allergic rhinitis, presence/absence of asthma, the peripheral eosinophil count (%) and the total REC score. In addition, the individual correlations between the above variables and the poor outcome group were analyzed by logistic regression analysis.

Results

The total REC score was 0 in only 35 (25.4%) of the total patients. The most common total REC scores were 1–6 in 85 (61.6%) patients. The superior-anterior part had the largest number of patients with an REC score of 1 or more. The satisfactory outcome group comprised 97 patients (70.3%), while the poor outcome group comprised 41 patients (29.7%). Comparison of these two groups found that the peripheral eosinophil count, the prevalence rate of asthma and the total REC score were each significantly higher in the poor outcome group than in the satisfactory outcome group. Logistic regression analysis identified a peripheral eosinophil count of ≥9.5%, the presence of asthma and a total REC score of ≥4 as factors that correlated significantly with a poor outcome.

Conclusion

The findings of this study indicate that RECs are involved in the recurrence of CRS following ESS. It can be thought that how to achieve full opening of the superior-anterior part of the ethmoid sinus, which includes the frontal recess, will be an issue in the future.     

Nuclear medicine studies of the regenerative behavior of paranasal sinus mucosa after functional endoscopic ethmoid bone surgery

The mucociliary clearance of the maxillary sinus mucosa was studied before and 6-18 months after functional sinus surgery using 99mTc-SC in 34 sinuses of 22 patients with chronic inflammation of the ethmoid and maxillary sinus. Before operation the mucociliary transport was very slow and sometimes absent. In the postoperative interval between 6 and 18 months we saw a significant return of the mucosal function. In 56% of the sinuses investigated the postoperative clearance rate was within the normal range. We also recorded a similar trend in allergic patients, although there was not such a clear return to normal of the mucociliary clearance, and the rates were not within the normal range. We found no recovery of the mucociliary function in 11 sinuses of 7 patients with impaired healing. Decisions on subsequent treatment were based on postoperative nasal endoscopy and functional mucosal repair.

An endoscopic study of tubal function and the diseased ethmoid sinus

Diseases of the paranasal sinuses--especially of the anterior ethmoid sinus--may affect tubal function. Acute and chronic sinus inflammations cause alterations in the normal pathways for secretions out of the sinus system. The normal secretion pathways usually bypass the orifice of the eustachian tube in the nasopharynx. Excessive or infected mucus can then be transported directly over the tubal orifice to cause its obstruction and promote ascending infections into the middle ear. We have found that nasal endoscopy proves to be very helpful in detecting even "hidden" pathologies due to sinus disease in key areas in the middle meatus, and furthermore allows a direct visualization of the tubal orifice. Functional endoscopic surgery has also enabled us to clear diseased and stenotic areas involving the sinus ostia with minimal procedures. Normal drainage and ventilation are reestablished via the physiologic sinus ostia and thus help to normalize tubal function.

Revision endoscopic sinus surgery

Patients with recurrent chronic sinusitis after prior surgical intervention pose a particular challenge to the otorhinolaryngologist. Establishing a correct diagnosis is the first step and requires review of the original presurgical symptoms and imaging; review of the more recent symptoms and images;and reevaluation of environmental, general, and local host factors that may contribute to persistent disease. Although primary chronic rhinosinusitis is typically a medical disease, postsurgical persistent disease may result directly from iatrogenic causes, requiring early surgical revision. Even in this setting, however, proper preoperative medical therapy is essential.Diagnostic evaluation should include meticulous endoscopic evaluation and appropriate radiologic studies. CT typically is required in the coronal and axial planes and ideally is performed using a computer-assisted surgical navigation protocol and with reconstructions in the sagittal plane, allowing for "scrolling" through the altered anatomy and conceptualizing the surgical issues at hand.When the decision to undergo revision surgery is made, the patient and the physician need to comprehend the rigorous and prolonged schedule of postoperative care and débridements that may be required for long-term success. Appropriate surgical technique emphasizing mucosal preservation and complete dissection must be adhered to. The surgeon must be aware that bony thickening is likely to be present and to make the dissection significantly more difficult than in the primary case. Medical management and endoscopic surveillance postoperatively is continued until a stable cavity is achieved.

Computer-aided endoscopic sinus surgery

Objectives: To examine four different types of computer-aided endoscopic sinus surgical devices—the ISG Viewing Wand, the ISG infrared OptoTrak, the IGT FlashPoint 5000, and the VTI InstaTrak—with emphasis on their accuracy and ease of use. Study Design: Prospective study utilizing laboratory experiments and intraoperative data collection. Methods: A review of the literature is presented. Patients undergoing endoscopic sinus surgery during the study period were enlisted under FDA protocols with IRB consent. Groups of patients had surgery performed with each of the above devices—except the FlashPoint 5000. Accuracy measurements were recorded, and user and operating staff comments about ease of use were collected. The FlashPoint 5000 was used exclusively in the laboratory setting, where accuracy measurements were obtained on a cadaver skull. Results: The systems all demonstrated accuracy to within 2.00 mm. Ease of use was somewhat variable, but following a learning curve by the surgeon and operating department personnel, all of the units were considered to be relatively user friendly. Conclusions: Computer-aided endoscopic sinus surgery appears to be the wave of the future. Nevertheless, the modern endoscopic sinus surgeon must have thorough training in the basic anatomy of the paranasal sinuses as well as the various surgical techniques.
