Comparison of natural ostiodilatation and endoscopic sinus surgery in the same patient with chronic sinusitis

INTRODUCTION

Chronic rhinosinusitis is a broad clinical syndrome characterized by mucosal inflammation of the nose and paranasal sinuses. In order for the paranasal sinuses to maintain their physiological functions; the ostiomeatal complex drainage pathways must be open. Surgical procedures are an important treatment option in patients who do not respond adequately to medical treatment. Although the methods and instruments used in functional endoscopic sinus surgery have continued to improve in recent years, the scar tissue formed during operation disrupts the drainage of the sinuses and reduces postoperative success. The natural ostiodilatation method, which is performed by balloon sinoplasty method, has become more and more popular in recent years.

OBJECTIVES

To compare the technique of balloon sinoplasty with the classical functional endoscopic sinus surgery method by considering the severity of chronic sinusitis on the same patient.

METHODS

Total of 61 chronic sinusitis patients was included in the study. Paranasal sinus tomography of the patients was taken and according to the Lund-Mackay scoring, chronic sinusitis levels were determined. Cases were divided into two groups: Group 1 (severe chronic sinusitis group) and Group 2 (mild chronic sinusitis).

RESULTS

There was no statistically significant difference in the results of comparison of sinuses which underwent balloon sinoplasty and classical functional endoscopic sinus surgery in Group 2 after Lund-Mackay scores. However in Group 1, the results of the comparison of postoperative Lund-Mackay scores of the balloon sinoplasty and the classical endoscopic operation were statistically significantly lower than those of the face half operated with the classical functional endoscopic sinus surgery.

CONCLUSION

The success of balloon sinoplasty in patients with mild sinusitis is the same as in classic functional endoscopic sinus surgery. However, as the severity of sinusitis increases, the efficacy of balloon sinoplasty decreases.

Isolated Inferior Rectus Muscle Entrapment following Endoscopic Sinus Surgery

Orbital complications are known risks of endoscopic sinus surgery (ESS). The lamina papyracea and medial rectus muscle are the most commonly injured structures during ESS. Inferior rectus injury is more rare, with only one reported case of isolated inferior rectus injury in the literature. Guidelines for managing ESS-induced inferior rectus injury do not exist, and delayed intervention and management of adjacent sinuses may affect long-term outcomes such as persistent diplopia and disfigurement. In this report, we present a case of a 67-year-old man with diplopia due to isolated left inferior rectus muscle entrapment and injury from violation of the orbital floor during previous ESS. We postulate that an incomplete maxillary antrostomy contributed to scar band formation and entrapment of the inferior rectus muscle after the orbital floor was violated, and advocate early intervention with a wide, complete maxillary antrostomy if the orbital floor is injured during ESS.

Correlation of Complications during Endoscopic Sinus Surgery with Surgeon Skill Level and Extent of Surgery

Background

Endoscopic sinus surgery (ESS) produces a great range of potential complications. Rough segregation into “minor” and “major” complications seems insufficient. This study uses a recently published new classification system that is based more on the patient's point of view, with a greater variety of options.

Methods

A retrospective review was undertaken of 421 ESS procedures. Both, the surgeon's experience and the extent of surgery were correlated with the complication rate.

Results

The overall complication rate was 39.7% (grades A–D) and did not correlate significantly with either the experience of the surgeon or with the extent of surgery.

Conclusion

The new classification is simple, precise, and takes complications into account that used to be neglected. ESS is even safe in the hands of less skilled surgeons as long as the degree of difficulty stays highly adapted to his/her ability. Some complications (grade A) seem to be inherent to the procedure.

Enhanced Irrigant Delivery to the Ethmoid Sinuses Directly Following Ethmoid Punch Sinusotomy

OBJECTIVES

Ethmoid punch sinusotomy (EPS) is a feasible treatment for ethmoid sinusitis in a subset of chronic rhinosinusitis (CRS) patients per a recent report. This adjunctive work investigates the technical characteristics of EPS and determines if EPS measurably alters the topical delivery of irrigant into the ethmoid sinuses in a cadaveric model.

METHODS

The sinonasal cavities of 10 human cadaver heads were irrigated with a solution containing methylene blue and radio-opaque contrast prior to and following EPS. Procedural characteristics and irrigant distribution were assessed by endoscopy and computed tomography.

RESULTS

Forty EPS procedures were performed through the ethmoid bulla and basal lamella. Compared to controls, EPS enhanced dye distribution into the anterior (90% vs 35%, P < .004) and posterior (90% vs 35%, P < .002) ethmoid sinuses, representing a 157% increase for each of these sites. Contrast was detected in a higher proportion of anterior (65% vs 5%, P < .001) and posterior (60% vs 0%, P < .001) ethmoid sinuses. Endoscopically guided catheter instillation of contrast through the EPS sites achieved radiotracer distribution throughout the ethmoid complex.

CONCLUSIONS

Ethmoid punch sinusotomy sites can be reliably created via micro-minimally invasive procedures. Ethmoid punch sinusotomy improves irrigant delivery to the ethmoid sinuses, providing mechanistic understanding for the clinical outcomes observed in CRS patients.

Safe treatment of ethmoid sinusitis utilizing minimally invasive ethmoid punch sinusotomy in chronic rhinosinusitis without polyposis patients

OBJECTIVES/HYPOTHESIS

Current rhinologic practice is devoid of minimally invasive procedures dedicated to the treatment of ethmoid sinusitis to improve ventilation and topical drug delivery. We have recently described a handheld spiral punch to create minimally invasive ethmoid punch sinusotomy (EPS) sites into the ethmoid bulla and basal lamella, which significantly increased irrigant access to the ethmoid sinuses in cadaver models. Here, we conducted a clinical feasibility study to determine the initial safety evaluation of EPS in chronic rhinosinusitis without polyposis (CRSsNP) patients with active ethmoid disease.

STUDY DESIGN

Single-arm, institutional review board-approved observational study.

METHODS

This study was performed in CRSsNP patients who failed medical management; were candidates for standard, traditional functional endoscopic sinus surgery; and were offered the option of EPS. EPS characteristics (patency, remucosalization) and complications (closure, mucus recirculation) were collected. Alterations in radiographic disease and symptoms after EPS were determined by Lund Mackay (LM) scoring and 22-item Sinonasal Outcome Test (SNOT-22) scoring, which was collected up to 6 months post-procedure.

RESULTS

Thirty-two of 40 possible ethmoid compartments (17 of 20 anterior, 15 of 20 posterior) underwent EPS. Twenty-nine of 32 EPS sites remained patent (n = 29, 90.6%), with a minority displaying evidence of restenosis (n = 9, 28.1%) or closure (n = 3, 9.3%). All patent EPS sites had complete remucosalization (n = 29, 100%) with no evidence of mucus recirculation (n = 0, 0%) or other complications secondary to healing or device use. Ethmoid sinus cavities with a pre-EPS LM score of 1 or 2 universally improved to an LM score of 0 following EPS (n = 30 of 30, 100%). SNOT-22 scores significantly improved, with a mean reduction of 33.1 (49.6 ± 7.5 pre-EPS vs 16.5 ± 7.7 post-EPS, p < .0001).

CONCLUSIONS

This feasibility study demonstrates that EPS appears to be a safe, minimally invasive procedure to treat ethmoid sinusitis in CRSsNP patients unresponsive to medical therapy that establishes ethmoid ventilation, and likely improves effective sinus irrigation. Conducting a clinical trial would be appropriate in assessing a potential role for EPS in the management of this condition.

A case report of unusual pneumomediastinum after endoscopic sinus surgery

INTRODUCTION

Endoscopic sinus surgery is a minimally invasive procedure used to restore normal sinus ventilation and mucociliary function. It is a routine otolaryngology procedure with a success rate of about 90% for symptomatic improvement in patients with refractory chronic rhinosinusitis. Because of the proximity of the paranasal sinuses to the brain and the orbit, it cannot be performed without a potential risk of complications. In our case, without early clinical suspicion, proper diagnosis and management, this unusual occurrence of pneumomediastinum after endoscopic sinus surgery may have led to major complications or even death.

PRESENTATION OF CASE

We report a case of unusual mediastinal emphysema in a 53-year-old man after removal of the nasal pack on the day after endoscopic sinus surgery.

DISCUSSION

To the best of our knowledge, there are only two reported cases of mediastinal emphysema after endoscopic sinus surgery. What made our case unique was the absence of smoking history, pulmonary disease or infection and normal preoperative chest CT scan. We investigated further with postoperative chest CT scan, bronchoscopy and esophagoscopy to rule out anesthesia related laryngotracheal injury. In our case, the pneumomediastinum was successfully treated conservatively; however, it could have proceeded to mediastinitis, septicemia and death if it had not been diagnosed and treated early.

CONCLUSION

Damage to the lamina papyracea can occur during endoscopic sinus surgery and presents as periorbital emphysema. Extension of the emphysema down to the mediastinum cannot be ignored as a possible etiology of the pneumomediastinum. Early diagnosis and proper management are important to avoid mortality.

Surgical management of rhinosinusitis in onco-hematological patients

Objectives

In onco-hematological diseases, the incidence of paranasal sinuses infection dramatically increase and requires a combination of medical and surgical therapy. Balloon dilatation surgery (DS) is a minimally invasive, tissue preserving procedure. The study evaluates the results of DS for rhinosinusitis in immunocompromised patients.

Methods

A retrospective chart review was conducted in 110 hematologic patients with rhinosinusitis. Twenty-five patients were treated with DS technique and 85 patients with endoscopic sinus surgery (ESS). We considered the type of anesthesia and the extent of intra- and postoperative bleeding. Patients underwent Sino-Nasal Outcome Test (SNOT-20) to evaluate changes in subjective symptoms and global patient assessment (GPA) questionnaire to value patient satisfaction.

Results

Local anesthesia was employed in 8 cases of DS and in 15 of ESS. In 50 ESS patients, an anterior nasal packing was placed and in 12 cases a repacking was necessary. In the DS group, nasal packing was required in 8 cases and in 2 cases a repacking was placed (P=0.019 and P=0.422, respectively). The SNOT-20 change score showed significant improvement of health status in both groups. However the DS group showed a major improvement in 3 voices: need to blow nose, runny nose, and facial pain/pressure. The 3-month follow-up GPA questionnaire showed an higher satisfaction of DS group.

Conclusion

Balloon DS represents a potentially low aggressive treatment and appears to be relatively safe and effective in onco-hematologic patients. All these remarks may lead the surgeon to consider a larger number of candidates for surgical procedure.

In-office functional endoscopic sinus surgery for chronic rhinosinusitis utilizing balloon catheter dilation technology

PURPOSE OF REVIEW

Balloon catheter dilation (BCD) technology was introduced in 2005 as a device employed to dilate maxillary, sphenoid, and frontal sinus outflow tracts in patients with chronic sinus disease. With the evolution of the technology, BCD has been utilized in the office setting. The purpose of this review is to discuss the safety, tolerability, and technical success of this change of venue and to consider the possible significant cost savings in the current healthcare environment.

RECENT FINDINGS

Recent studies have shown that BCD technology can be safely and successfully used in the office setting with high patient satisfaction and symptom improvement similar to that achieved in the operating room.

SUMMARY

In select patients with chronic sinus disease, BCD can be safely and effectively utilized to open compromised outflow tracts from the peripheral sinuses including the maxillary, sphenoid, and frontal sinuses. This has the potential to reduce the overall costs related to the surgical treatment of medically refractory sinus disease.

[Endoscopic sinus surgery complications a prospective multicenter study]

OBJECTIVE

Our objective was to determine the rate of complications in endoscopic sinus surgery (ESS) and associated risk factors.

METHODS

We prospectively studied 1,382 subjects undergoing ESS for rhinosinusitis and cystic sinus disease at 16 hospitals during 2007 and 2008. Surgeons provided information on peri-and postoperative complication occurrence.

RESULT

Results of complications were seen in 80 subjects (5.8%), the most frequent was perioperative lamina papyracea injury. Analysis showed the complication rate to be linked to gender, and anesthesia type, but not the grade of surgeon.

CONCLUSIONS

While care should be taken to avoid them, complications should be identified and treated in a timely and accurate manner.

Risk factors for complications of endoscopic sinus surgery for chronic rhinosinusitis

BACKGROUND

Patients undergoing endoscopic sinus surgery (ESS) are at risk of complications because of the close proximity of the sinuses to the orbit and anterior skull base. The aim of this study was to evaluate the complications of ESS and to identify patient characteristics that were risk factors for the complications.

METHODS

We conducted a prospective study of 706 patients who underwent ESS for chronic rhinosinusitis. Patients completed preoperative examinations that included computed tomography, endoscopic observation for nasal polyps, and tests for comorbidities including asthma and vascular disease. Perioperative complications were evaluated based on information provided by the surgeons. Multivariate analysis was performed to identify patient characteristics that were risk factors for complications.

RESULTS

Overall, perioperative complications occurred in 41 patients (5.8%). A major complication, cerebrospinal fluid leakage, occurred in one patient (0.1%). Minor complications occurred in 40 patients (5.7%), with the most common being intraoperative hemorrhage (n = 18). Multivariate analysis indicated that presence of asthma and the total polyp score correlated significantly with the occurrence of complications.

CONCLUSION

The risk factors for perioperative complications were asthma and the polyp score. We conclude that the surgeon should confirm whether the patient has lower airway disease, especially asthma, before operating. The surgeon should also determine the grade of nasal polyps.

Complications of hyoid suspension in the treatment of obstructive sleep apnea syndrome

The objectives of the study are to assess adverse events and complications of hyoid suspension (HS) as a treatment of obstructive sleep apnea syndrome (OSAS). The study design was cohort. Thirty-nine patients with OSAS and obstruction at tongue base level, as assessed by sleep endoscopy, underwent HS. Information about adverse events and complications were obtained by reviewing charts and patient-completed questionnaires. The mean follow-up period from surgery to last control visit was 13.1 months (range 2-38). The charts demonstrated mainly adverse events. Minor complications occurred in six patients. No major complications were observed. The mean admission duration was 3.3 days (range 2-5). Twenty-six patients (67%) returned their questionnaires. No association was found between completing questionnaires and the success of the intervention (p = 0.73). The questionnaires were completed on average 25.9 months (range 3.5-51.5) after surgery. VAS scores showed a fast decline in complaints regarding taste, speech, swallowing and pain. No significant long-term differences were found, when comparing the postoperative VAS scores with the preoperative VAS scores. Of the 26 evaluable questionnaires, 20 patients (77%) would recommend HS to an acquaintance if they suffered from sleep apnea syndrome, when only taking side effects into consideration. The intention to give a positive recommendation did not seem to be related to the therapeutic success of the intervention. In conclusion, this study demonstrates that the complication rate of HS is low and that the discomfort is very acceptable.

Is severe epistaxis associated with acetylsalicylic acid intake?

OBJECTIVES/HYPOTHESIS

Epistaxis represents a very common emergency in any ear, nose, and throat (ENT) department around the world. Despite other risk factors, acetylsalicylic acid (ASA) contributes to nosebleeds by its intrinsic ability to impair thrombocyte aggregation. The aim of this study was to investigate the influence of ASA on the severity of epistaxis and to compare it with other potential risk factors.

STUDY DESIGN

A prospective cohort study was performed at the ENT department of University Hospital Zurich.

METHODS

A total of 591 events were evaluated concerning surgical interventions and the length of in-hospital stay. Further analyses regarding recurrences and number of treatments and a specially designed severity score, as well as other outcome parameters, were performed.

RESULTS

Ninety-nine patients needed to stay in-hospital for at least 1 day. Nearly 30% of all patients had ASA intake, and only 18% were on vitamin K antagonist therapy. Patients on ASA showed significantly more surgical interventions, a higher recurrence rate, and a larger number of required treatments as well as an increased severity score. Duration of in-hospital stay and the complication rate, however, were not associated with drug intake.

CONCLUSIONS

We not only identified ASA to be one of the major risk factors in epistaxis, but also quantified its impact on the severity of nose bleeding. We emphasize the importance of a well-indicated antiaggregational therapy, and strongly discourage using ASA as a life-style drug for the elderly. ASA therapy needs to be discontinued whenever possible and reasonable.

Endoscopic Balloon Dilation Sinuplasty Including Ethmoidal Air Cells in Chronic Rhinosinusitis

Objectives:

We present the results of our experience with balloon catheter sinusotomy (BCS) in patients who had chronic rhinosinusitis.

Methods:

The medical records of 30 patients who were treated for chronic sinusitis with the BCS technique between April 2007 and February 2008 were reviewed retrospectively. Preoperative and postoperative assessments were performed by endoscopic endonasal examination and Lund-Mackay radiologic staging of paranasal sinus computed tomography scans. The symptom scoring was performed with the Sino-Nasal Outcome Test–20 (SNOT-20). The postoperative follow-up period was at least 12 months.

Results:

We performed BCS in 151 sinuses, excluding 2 maxillary and 2 frontal sinuses. No major complication attributable to BCS was observed. After operation, suctioning and crust removal was not needed in the area operated on in BCS patients. Revision surgery was needed in 2 patients after 6 months. From before to after operation, the SNOT-20 values and Lund-Mackay scores decreased significantly.

Conclusions:

We conclude that BCS helps to dilate the sinus ostia properly and effectively in the management of chronic rhinosinusitis. It can also be performed in the ethmoidal air cell area.

Safety in endoscopic sinus surgery

PURPOSE OF REVIEW

Endoscopic sinus surgery techniques and technologies have undergone rapid development over the past two decades. Recently, image guided systems have been implemented in endoscopic sinus surgery, carrying the promise of increased safety during surgery. This review compiles available data regarding the incidence of complications in endoscopic sinus surgery, the trends over time, and the impact of image guided surgery on complication rates.

RECENT FINDINGS

Reporting of complications in endoscopic sinus surgery is widely variable, confounding attempts to establish accurate data regarding complication rates. Few prospective, randomized trials exist comparing the safety of functional endoscopic sinus surgery with other surgical techniques. Major complications occur in 0-1.5% of cases and minor complications occur in 1.1-20.8% of functional endoscopic sinus surgery cases. Powered instrumentation does not appear to affect the incidence of complications, but may increase the severity of complications. It is unclear whether image guided surgery results in lower complication rates. Practical and ethical considerations make randomized trials to evaluate this issue problematic.

SUMMARY

In order to maximize safety, functional endoscopic sinus surgery surgeons must individually and collectively audit current practice, report complications in a systematic way, utilize available technology appropriately to support safe surgery, and diligently refine surgical technique as well as the systems supporting endoscopic surgical practice.

Multicenter Registry of Balloon Catheter Sinusotomy Outcomes for 1,036 Patients

Objectives:

This study assesses the safety and effectiveness of balloon catheters used as instruments in sinus surgery in a “real-world” multicenter registry of 1,036 patients across 27 US otolaryngology practices.

Methods:

Data were collected by standardized chart review with centralized database administration for all consecutive functional endoscopic sinus surgeries that included the use of balloon catheters across the 18-month time period from December 2005 to May 2007.

Results:

Balloon catheters were used in 3,276 peripheral (maxillary, frontal, and sphenoid) sinuses, for an average of 3.2 sinuses per patient. There were no major adverse events related to the use of balloon catheter instruments. The revision rate was 1.3% of sinuses treated with a balloon catheter after an average follow-up of 40.2 weeks. Sinus symptoms were improved in 95.2%, unchanged in 3.8%, and worse in 1.0% of patients. Postoperative sinus infections were significantly less frequent and less severe compared to infections before surgery. The results were consistent across all patient categories, including balloon-only patients and revision patients.

Conclusions:

Use of balloon catheters as instruments in sinus surgery appears to be relatively safe and effective and to improve the patient's quality of life. The results are consistent and generalizable across a wide range of sinusitis patients and physician practices. The complication rates, revision rates, and patient symptom improvement rates all compare favorably with previously reported results of functional endoscopic sinus surgery.

UPPP combined with radiofrequency thermotherapy of the tongue base for the treatment of obstructive sleep apnea syndrome

We investigated the outcome of uvulopalatopharyngoplasty (UPPP) combined with radiofrequency thermotherapy of the tongue base (RFTB) in patients with obstructive sleep apnea syndrome (OSAS) with both palatal and retroglossal obstruction, and we compared these results with the results of single level surgery (UPPP). A retrospective cohort study was performed in patients with mild to severe OSAS who underwent UPPP with or without RFTB. Seventy-five patients with both palatal and retroglossal obstruction underwent UPPP, 38 patients without RFTB (group 1) and 37 patients with RFTB (group 2). The outcome of the surgery was measured by both objective success (defined as a reduction of AHI >50% and AHI below 20) and subjective improvement. In group 1 the overall success rate was 42%, and in group 2 49%. Other polysomnographic values (AI, DI, mean SaO2) improved after surgery (not significant). No serious adverse events occurred. Surgical treatment of combined palatal and retroglossal obstruction remains a challenge. Adding RFTB to UPPP results in a mild improvement compared to UPPP alone. Although the addition of RFTB to UPPP seems to result in only a limited improvement, there is no major downside to it. RFTB is well tolerated and safe.

Steroid injection for sinonasal polyps: the University of Virginia experience

BACKGROUND

Sinonasal polyps are treated with topical steroids, systemic oral steroids, surgical excision, and intrapolyp steroid injection. Use of steroid injection is not widespread because of reported complications. The objective of this study was to evaluate the complications of intrapolyp steroid injections and compare it to the complications of surgical removal of polyps.

METHODS

All patients seen between 1994 and 2003 with a diagnosis of nasal polyps were reviewed retrospectively. Demographics, complications, follow-up, and comorbidities were collected. Frequency of each treatment modality used and complications of each treatment were compared.

RESULTS

Three hundred fifty-eight patients were in the study with a mean follow-up of 30 months. Respiratory comorbidities were asthma alone (35%), aspirin triad (16%), and cystic fibrosis (15%). Other comorbidities were smokers (21%). Treatment modalities were medical treatment alone (14%); medical treatment and steroid injections (19%); medical treatment and surgery (33%); and medical treatment, injections, and surgery (34%). Patients who underwent injection had fewer surgeries (p < 0.001). There was 1 minor complication associated with 1495 injections and 11 major and 16 minor complications associated with the 310 surgeries. The differences in complication rates were statistically significant (p < 0.001). There was no significant difference in demographics, follow-up, or comorbidities between patients who received injections and patients who underwent surgery.

CONCLUSION

Intrapolyp steroid injection is associated with a significantly lower rate of complication than is surgical excision of sinonasal polyps. Steroid injection also may decrease the need for further surgical intervention of polyps.

Bipolar radiofrequency induced thermotherapy of the tongue base: Its complications, acceptance and effectiveness under local anesthesia

We assessed adverse events and complications of bipolar radiofrequency induced thermotherapy of the tongue base (RFTB) in patients with socially unacceptable snoring (SUS) or obstructive sleep apnea syndrome (OSAS) and determine its acceptance and effectiveness when conducted under local anesthesia. This investigation consisted of (1) a prospective, open-enrollment study of 24 consecutive patients with snoring and OSAS at the tongue base level only (Fujita III), assessed by sleep endoscopy. Polysomnography, questionnaires, and visual analog scales (VAS) were used to assess outcome. (2) In addition, a retrospective review of 83 patients, who underwent RFTB (in 59 cases as part of a multilevel treatment), was performed to evaluate adverse events and complications. Twenty-two of the 24 patients completed postoperative questionnaires and VAS, and ten patients had postoperative polysomnography. Reduction in snoring (P = 0.0003), hypersomnolence (P = 0.002), and globus (P = 0.031) was significant. A positive trend in AHI (P = 0.001, n = 3) is shown in patients with moderate to severe OSAS. Concerning postoperative adverse events and complications, only two patients had a mild and transient tongue deviation directly after the procedure, which resolved within an hour postoperatively (adverse event rate 1.8%). No postoperative complications such as infections, abscesses, hematomas, or ulcerations of the tongue base occurred. This study demonstrates that bipolar RFTB in patients with obstruction at the tongue base only (Fujita type III) as visualized by sleep endoscopy is a safe and simple procedure under local anesthesia and can be effective in patients with SUS. No complications during this study were observed. Its effect on OSAS has been shown by other authors, although long-term effects are not stable. The RFTB can be considered as first choice treatment in case of snoring and mild OSAS in Fujita type III obstruction. In the case of moderate to severe sleep apnea, RFTB can be considered as an additional treatment.
