Endoscopic sphenopalatine artery ligation is an effective method of treatment for posterior epistaxis

Endoscopic Sphenopalatine Artery Cauterization in the Management of Recurrent Posterior Epistaxis

Background and Objectives: Endoscopic sphenopalatine artery cauterization (ESPAC) has become a reliable and effective surgical procedure for managing posterior epistaxis. The objectives of our study were to evaluate the effectiveness of ESPAC in the management of posterior epistaxis and the possible factors that lead to the failure of the procedure. Materials and Methods: We performed a retrospective analysis of all patients who underwent ESPAC between 2018 and 2022. We retrospectively reviewed the demographic data, patients' co-morbidities, medical treatment conditions, whether other surgical procedures were performed in addition to the ESPAC, and the success rate of ESPAC. Results: 28 patients were included in our study. After ESPAC, epistaxis was successfully managed in 25 patients (89.28%). Of all patients undergoing ESPAC, three (10.7%) presented re-bleeding. In two patients, we performed an endoscopic revision surgery with re-cauterization of the sphenopalatine foramen area, together with anterior and posterior ethmoidectomy, followed by fat occlusion/obliteration of these sinuses. In one patient, fat obliteration of the anterior and posterior ethmoid was also unsuccessful, and we performed an external carotid artery ligation at the level of the neck with no recurrence afterwards. Conclusions: Endoscopic cauterization of the sphenopalatine artery remains a safe, effective, and reliable surgical procedure in the management of recurrent posterior epistaxis. The use of anticoagulant drugs and the association of hypertension and other heart and liver diseases do not materialize as factors influencing surgical failure.

The Quadrangular Space, Endonasal Access to the Meckel Cave: Technical Considerations and Clinical Series

OBJECTIVE

An anteromedial corridor via an expanded endoscopic endonasal approach to the Meckel cave (MC) was described more than a decade ago. However, few clinical series or endoscopic endonasal technical contributions exist concerning this type of approach to this complex region.

METHODS

We present a detailed description of the surgical technique for this approach reviewing the original technique and adding clarifying conceptual notions. We conducted a multicenter retrospective study selecting patients who underwent endonasal endoscopic surgery for lesions exclusively limited to the MC in the past 6 years. Intraoperative and postoperative complications were analyzed. The study of 10 cadaveric specimens provides additional information.

RESULTS

We performed a fully endoscopic anteromedial corridor to the MC in 18 patients. The most prevalent pathologic finding was schwannoma of the V nerve in 4 patients. Sixth cranial nerve palsy (13 patients) and trigeminal dysfunction (10 patients) were the predominant preoperative clinical signs. There were no remarkable intraoperative complications. Corneal keratopathy caused by dry eye syndrome affected 3 patients and V2 residual neuralgia appeared postoperatively in 2 patients. Six patients recovered from sixth cranial nerve palsy, and 2 showed improvement in preoperatively referred facial pain.

CONCLUSIONS

The front door to the MC via the endonasal anteromedial corridor could be a good option. Understanding of the anatomy and the concept of the quadrangular space is crucial to performing this technique safely, which has few complications in experienced hands. Recovery from sixth nerve palsy is possible with this approach. Corneal keratopathy in these patients is a potential complication.

Delayed Bleeding of Sphenopalatine Artery as a Complication in Le Fort I Osteotomy

ABSTRACT

Rates of severe complications in orthognathic surgery are low, but when they occur they can be fatal. This article reports a case of laceration of the junction of the posterior lateral nasal artery and the sphenopalatine artery, resulting in severe delayed bleeding. Patient undergoes a multiple segment Le Fort I osteotomy with no intraoperative or immediate postoperative complications. On the fourth postoperative day, he presents with epistaxis and intractable postnasal discharge, is admitted to emergency with signs of shock, and bleeding is detected endoscopically originating from the right sphenopalatine artery, which is treated with diathermocoagulation. The advantage of endoscopy in difficult areas is that bleeding complications can be solved with low morbidity.

An image-guided (CT) assessment of a new asymmetric balloon for the treatment of epistaxis

PURPOSE

The main objective was to perform an image-guided (CT) assessment of the efficacy of the CAVI-T™ balloon to compress the sphenopalatine artery (SPA) on cadaver heads, for the management of epistaxis. The secondary objectives were to analyse the deployment and stability of this balloon according to the volume injected into the nasal cavity, to optimise its use.

METHODS

A descriptive anatomical study was performed. The catheterization of the SPA was performed on four fresh-frozen heads with a SPA approach through the maxillary sinus, leaving the nasal cavity unscathed. Computed Tomography images were acquired without and with the balloon, inflated by injections of progressive volumes of diluted iodine, for optimal contrast with the surrounding tissues. We evaluated the positioning of the balloon according to two predetermined markers on the device.

RESULTS

Out of 68 image-guided acquisitions, the CAVI-T™ balloon compressed the SPA in 88% of cases. The other nasal cavity structures were compressed in 86% to 100% of the cases, depending on the positioning of the CAVI-T™ balloon, therefore allowing a complete obstruction of the nasal cavity. The device remained stable upon inflation and did not obstruct the nasopharynx.

CONCLUSION

The CAVI-T™ balloon provided effective compression of the SPA and the different structures of the nasal cavity.

Endoscopic sphenopalatine artery electrocoagulation for refractory epistaxis: a clinical study

BACKGROUND

The electrical coagulation of sphenopalatine artery(SPA) under nasal endoscopy has gradually become an important surgical intervention for epistaxis.

AIM

To investigate the effectiveness and complications of SPA electrocoagulation for epistaxis.

MATERIAL AND METHODS

The clinical data of 47 patients undergoing SPA electrocoagulation were analyzed, retrospectively.

RESULTS

Forty-seven patients were enrolled, with a male to female ratio of approximately 3:1. 11of 36 were under 45 years old, 25 of 36were 45 years old and above. Among female patients, one was under 45 years old, and the others were 45 years old and above, but there was no significant difference in gender composition between different age groups (χ ² = 1.069, p = .301). All patients were unilateral epistaxis. The effective control rates of epistaxis within 24 h after surgery, early postoperative, and late postoperative were 100%, 100%, and 97.9%, respectively. There were 6 patients with complications, including 3 patients with nasal dryness and ecdysis on the affected side, 2 patients with numbness on upper lip, 1 patient with nasal adhesion and pus on affected side.

CONCLUSION AND SIGNIFICANCE

Refractory epistaxis has no relationship with age and sex, SPA electrcoagulation can effectively control refractory epistaxis and is an effective surgical method.

Endovascular Embolization in the Treatment of Epistaxis

OBJECTIVE

The cost-effectiveness of endovascular embolization (EE) for intractable epistaxis has been questioned, especially as endoscopic surgical techniques have become standard of care at many institutions. Our objectives were to review the safety profile and effectiveness of EE for epistaxis.

STUDY DESIGN

Retrospective case series.

SETTING

Tertiary care hospital.

SUBJECTS

There were 54 patients and 64 unique encounters. Patients were 66.7% male, with a mean age of 64.5 years. Bleeding disorders were present in 18.8%, hypertension was present in 71.7%, and 61.1% were on anticoagulant/platelet drugs.

METHODS

Charts of patients undergoing EE for epistaxis between 2005 and 2015 were retrospectively reviewed.

RESULTS

The immediate bleeding control rate was 92.6%. Three patients died within 1 week of EE and were excluded from further analysis. Overall, 64.7% of the remaining patients had no further episodes of epistaxis. Thirteen patients (25.4%) rebled within 1 week, 11 of whom required repeat EE or operative control. Five patients (9.8%) rebled more than 1 week following the procedure with 4 requiring repeat EE or operative control. The major complication rate was 7.4% and included transient stroke, diplopia, facial skin necrosis, and extraperitoneal hemorrhage.

CONCLUSION

While the immediate success rate of EE for epistaxis was comparable to the literature, the overall short- and long-term rebleed rate was high in this selected population. The results suggest that patients who are referred for EE represent a high-risk group with increased risk of repeat hemorrhage and morbidity. Patients who undergo EE for epistaxis should be carefully monitored for complications, including repeat hemorrhage.

Sphenopalatine artery surgery for refractory idiopathic epistaxis: Systematic review and meta-analysis

OBJECTIVES

Epistaxis, especially posterior epistaxis, is occasionally refractory to treatment. In these cases, sphenopalatine artery surgeries, including cauterization and ligation, are required. Previous reports have demonstrated treatment results for these procedures but failed to provide high-level evidence. The aim of this study was to quantify the rates of failure and perioperative complications of these procedures by using a meta-analysis technique.

METHODS

We systematically searched electronic databases and identified articles regarding epistaxis, sphenopalatine artery ligation, or cauterization. Pooled rebleeding and complication rates were calculated by using a random effects model.

RESULTS

A total of 896 cases of sphenopalatine ligation or cauterization for epistaxis were analyzed. Pooled rebleeding rates for the entire cohort, cauterization group, and ligation group were 13.4% (95% confidence interval [CI] 10.0-17.8, P < 0.001), 7.2% (95% CI 4.6-11.0, P < 0.001), and 15.1% (95% CI 9.8-22.5, P < 0.001), respectively. Pooled perioperative complication rates for the entire cohort, cauterization group, and ligation group were 8.7% (95% CI 4.9-15.1, P < 0.001), 10.2% (95% CI 3.8-24.5, P < 0.001), and 6.4% (95% CI 1.8-20.9, P < 0.001), respectively.

CONCLUSION

Overall, sphenopalatine surgery for refractory epistaxis is an effective method because of its low rates of failure and complications. Cauterization is more effective than ligation, whereas complications are comparable between the two procedures. Laryngoscope, 129:1731-1736, 2019.

Endoscopic Anatomy of the Sphenopalatine and Posterior Nasal Arteries: Implications for the Endoscopic Management of Epistaxis

Background

Refractory posterior epistaxis is a challenge for otolaryngologists. Most algorithms for managing this condition ultimately call for interrupting the arterial blood supply to the nasal mucosa. Traditionally, this was accomplished either by transantral arterial ligation or by arteriographic-guided embolization. More recently, the endonasal endoscopic approach has also been described. Because the primary blood supply to the posterior nasal cavity is derived from the terminal branches of the sphenopalatine and the posterior nasal arteries, we conducted this anatomic study to examine and describe the anatomic relationship of these two arteries as they exit the pterygopalatine fossa and enter the nasal cavity.

Methods

We performed endoscopic dissections of this anatomic region in nine fresh and one formalin-preserved cadaver specimens. A total of 19 sides were examined.

Results

In 3 of 19 specimens (16%), the sphenopalatine artery branched from the sphenopalatine artery within the sphenopalatine canal, allowing the two arteries to exit together. In 8 of the 19 specimens (42%), the sphenopalatine artery exited much more posteriorly, yet from within a shared posteriorly elongated sphenopalatine foramen. In the remaining eight specimens (42%), the sphenopalatine artery exited through a distinct foramen directly posterior to the larger sphenopalatine foramen.

Conclusion

Understanding this anatomic relationship is important in performing endoscopic arterial ligation. If the sphenopalatine artery is not specifically identified and ligated, an important component of the posterior nasal circulation will not be addressed adequately by this surgical approach.

Embolization for the Treatment of Idiopathic Posterior Epistaxis

Background

The goal of this study was to examine safety and efficacy of transarterial embolization for the treatment of idiopathic posterior epistaxis.

Methods

A retrospective chart review was conducted to characterize the underlying conditions of eighty-one consecutive patients for whom complete records were available presenting with posterior epistaxis, the associated risk factors for patients with idiopathic posterior epistaxis, and the success rate of embolization in this patient population.

Results

One hundred consecutive patients undergoing embolization for epistaxis were identified and 81 patients were included in the analysis. Nineteen patients did not have sufficient and retrievable medical records to be included in the study. Idiopathic posterior epistaxis was the most common underlying etiology of patients with refractory posterior epistaxis (34%). Hypertension, vascular disease, and diabetes were frequently detected comorbid diseases. Patients were equally as likely to be hypertensive as normotensive at the time of presentation (45 and 55%, respectively). Most patients (83%) had failed at least one prior treatment modality. Few patients had a recurrence of epistaxis within 72 hours (three patients [12%]) or had an adverse effect associated with embolization (three patients [12%]).

Conclusion

Embolization for the treatment of posterior epistaxis is a safe and effective treatment modality.

An Endoscopic Study of the Greater Palatine Nerve

Background

Using an endoscopic approach, lateral sphenoid air cells and terminal branches of the internal maxillary artery often can be accessed through the pterygomaxillary fossa; however, injury to the greater palatine nerve (GPN) can occur if the anatomy of this region is not understood clearly. This study was undertaken to define the pathway of the GPN and to identify landmarks useful in preventing its injury.

Methods

Six cadaveric heads were used to endoscopically dissect and examine 11 pterygomaxillary fossae. An additional latex-injected cadaveric head was sectioned coronally and dissected bilaterally. The relationships between the vascular, neurological and bony structures and foramena were noted and described.

Results

All specimens studied maintained consistent relationships. The sphenopalatine and posterior nasal arteries cross nearly perpendicular and just superficial to the GPN. The GPN traveled anteriorly and inferiorly to reach the greater palatine foramen. The lateral wall of the canal ranged from a thin bony covering to complete dehiscence and was thinnest as it crossed the inferior turbinate and approached the foramen. The foramen rotundum was located lateral and superior to the sphenopalatine foramen near the roof of the maxillary sinus.

Conclusion

When surgically approaching the pterygomaxillary fossa, injury to the GPN is avoidable by thorough knowledge of anatomy and awareness of the described landmarks.

Successful Implementation of a Clinical Care Pathway for Management of Epistaxis at a Tertiary Care Center

OBJECTIVE

We compare the management of patients with severe epistaxis before and after the implementation a clinical care pathway (CCP) to standardize care, minimize hospital stay, and decrease cost.

STUDY DESIGN

Single prospective analysis with historical control.

SETTING

Tertiary academic hospital.

SUBJECTS AND METHODS

Patients treated for epistaxis between October 2012 to December 2013 were compared with a prospective analysis of patients treated for severe epistaxis after implementation of a CCP from June 2014 to February 2015. Severe epistaxis was defined as nasal bleeding not able to be controlled with local pressure, topical vasoconstrictors, or simple anterior packing.

RESULTS

Severe epistaxis was similar in the pre- and post-CCP cohorts: 24.7% (n = 42) vs 18.9% (n = 22), respectively. Implementation of early sphenopalatine artery ligation resulted in decreased number of days packed (3.2 ± 1.6 to 1.4 ± 1.6; P = .001), decreased hospital stay (5.2 ± 3.9 to 2.1 ± 1.3 days; P < .001), an increased percentage of sphenopalatine artery ligations (31.0% vs 54.5%; P = .035), admission to an appropriate hospital location with access to key resources (41.7% vs 83.3%; P = .007), and decreased overall cost of hospitalization by 66% ($9435 saved). No patients received embolization after the CCP was implemented.

CONCLUSIONS

Implementation of a CCP decreased hospital stay and days of packing, facilitated definitive care in patients with severe epistaxis, improved patient safety, and decreased cost. The results of this study can serve as a model for the management of severe epistaxis and for future quality improvement measures.

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Technical and surgical aspects of the sphenopalatine ganglion (SPG) microstimulator insertion procedure

Cluster headache (CH) is a debilitating, severe form of headache. A novel non-systemic therapy has been developed that produces therapeutic electrical stimulation to the sphenopalatine ganglion (SPG). A transoral surgical technique for inserting the Pulsante SPG Microstimulator into the pterygopalatine fossa (PPF) is presented herein. Technical aspects include detailed descriptions of the preoperative planning using computed tomography or cone beam computed tomography scans for presurgical digital microstimulator insertion into the patient-specific anatomy and intraoperative verification of microstimulator placement. Surgical aspects include techniques to insert the microstimulator into the proper midface location atraumatically. During the Pathway CH-1 and Pathway R-1 studies, 99 CH patients received an SPG microstimulator. Ninety-six had a microstimulator placed within the PPF during their initial procedure. Perioperative surgical sequelae included sensory disturbances, pain, and swelling. Follow-up procedures included placement of a second microstimulator on the opposite side (n=2), adjustment of the microstimulator lead location (n=13), re-placement after initial unsuccessful placement (n=1), and removal (n=5). This SPG microstimulator insertion procedure has sequelae comparable to other oral cavity procedures including tooth extractions, sinus surgery, and dental implant placement. Twenty-five of 29 subjects (86%) completing a self-assessment questionnaire indicated that the surgical effects were tolerable and 90% would make the same decision again.

The high rate of long-term recurrences and sequelae after epistaxis treatment

OBJECTIVE

Epistaxis is the most frequent rhinologic emergency with a high treatment morbidity. This study assessed the long-term outcome after epistaxis treatment with regard to patient comfort during the treatment, long-term complications and rate of recurrences.

METHODS

A questionnaire cohort study was performed at the ENT department of the University Hospital Zurich. In April 2014, 363 patients were contacted, who were treated between March 2007 and April 2008 for the reason of epistaxis using a written questionnaire to elucidate the patients' condition after the treatment. The type of treatment, subjective discomfort as well as degree of pain, complications, permanent sequelae and recurrences were assessed.

RESULTS

109 questionnaires were analyzed (response rate of 36%). The overall same-sided recurrence rate after successful treatment during the 6.4-year follow-up was 22%. Discomfort was reported in 48% after cautery, 86% after packing and in 11% after surgery. Strong or very strong pain was perceived in 8% after cautery, 26% after packing and in 0% after surgery alone. Complications consisted of nasal crusting in 15% after cautery and nasal breathing impairment in 24% after packing. Permanent harm was reported in 4% after cautery versus 20% after packing plus surgery.

CONCLUSIONS

The data confirm the high rate of recurrences despite adequate treatment in the long-term analysis. The rate of post-treatment complications is considerably high with nasal crusting being the main inconvenience. It further shows that patients keep a vivid memory of the treatment even many years later and that packing is extremely uncomfortable to patients.

Chapter 3: Epistaxis

Epistaxis is a common problem that may range in severity from a minor nuisance to hemodynamically significant bleeding. Vascular anatomy allows for predictable identification of suspicious bleeding sites. Historically, packing was the workhorse of management, but, currently, more directed interventions have become available. These modalities may result in improvements in both cost-effectiveness and patient comfort.

Anatomical and surgical study of the sphenopalatine artery branches

The sphenopalatine artery gives off two main branches: the posterior lateral nasal branch and the posterior septal branch. From 2007 to 2012 17 patients were treated with cauterization and/or ligature of the sphenopalatine artery with endonasal endoscopic approach. 90 nasal dissections were performed in 45 adult cadaveric heads. We evaluated the number of branches emerging from the sphenopalatine foramen and the presence of an accessory foramen. In the surgery group, we observed a single trunk in 76% of the patients (13/17) and a double trunk in 24% (4/17). We found an accessory foramen in four cases. We obtained a successful result in bleeding control in 88% of the cases. In the cadaver dissection group, 55 nasal cavities had a single arterial trunk (61%), 30 had 2 arterial trunks (33%) and in only 5 nasal fossae we observed 3 arterial trunks (6%). We were able to dissect four accessory foramina. We suggest that in most cases only one or two branches are found in the sphenopalatine foramen.

Endoscopic identification of the pharyngeal (palatovaginal) canal: an overlooked area

Objective The pharyngeal or palatovaginal canal (PC) is a small tunnel that lies between the sphenoid process of the palatine bone and the vaginal process of the sphenoid bone. Currently, little endoscopic information is available about this region. Design and Setting Endoscopic endonasal cadaveric study. Subjects and Methods Twenty sides in 10 adult cadaver heads were studied endoscopically. The sphenopalatine foramen (SPF) and the adjacent pterygopalatine fossa were exposed. Dissection medial to the vidian canal demonstrated a tunnel that runs posteromedially in the sphenoid floor. Endoscopic data were documented. Additionally, canal measurements were obtained on 20 sides from coronal CT scans of paranasal sinuses. Results The PC was identifiable in 85% of the sides, although thickness of its bony wall was variable. The endoscopic relationship of the canal and its artery with other landmarks is described. Radiologically, the diameter of the PC averaged 1.7 mm, and the mean distance from the PC to the vidian canal was 3.78 mm. Conclusion The current study provides a novel endoscopic identification of an overlooked canal. The pharyngeal artery can be a source of bleeding during extended endoscopic procedures. The PC itself could be a place for finger-like projections of anatomically related neoplasms.

Septal perforation and bilateral partial middle turbinate necrosis after bilateral sphenopalatine artery ligation

OBJECTIVE

To report previously unreported complications of bilateral sphenopalatine artery ligation.

SUBJECTS AND METHODS

We present the case of a 45-year-old man who underwent bilateral sphenopalatine artery ligation to control intractable posterior epistaxis. After four months, he re-presented with nasal obstruction and crusting.

RESULTS AND ANALYSIS

Examination under general anaesthesia showed posterior septal perforation and bilateral necrosis of the lower parts of the middle turbinates. The necrotic parts were excised. The patient had no more complaints.

CONCLUSION

Following sphenopalatine artery occlusion, ischaemic necrosis is a potential risk in anatomical areas that receive their only arterial supply from this artery. The staging of bilateral sphenopalatine artery occlusion needs to be studied.

National long-lasting effect of endonasal endoscopic sphenopalatine artery clipping for epistaxis

CONCLUSION

We consider sphenopalatine artery ligation to be a safe and effective treatment of posterior epistaxis as the long-term need for revision surgery and the complication rates are low. Surgery should be considered earlier in the treatment of posterior epistaxis.

OBJECTIVES

Posterior epistaxis is common and surgical endoscopic ligation of the sphenopalatine arteries is indicated in severe cases. Knowledge about long-term effects and complications is sparse.

METHODS

Within 2001-2006, 78 patients underwent endonasal endoscopic-guided surgery for posterior epistaxis in one of the eight ENT clinics in Denmark treating these patients. In 2011, 45 patients were still alive and eligible for the study. Patients were contacted by telephone and invited to complete an interview questionnaire on late adverse affects and recurrence.

RESULTS

In all, 42 of 45 patients participated in the mean follow-up. The mean follow-up was 6.7 years: 90% of patients (n = 38) obtained an effect of the treatment during follow-up; 78% (n = 33) had no recurrent epistaxis, 12% (n = 5) had recurrent epistaxis but only needed non-surgical specialized treatment; 10% (n = 4) required revision surgery due to recurrent epistaxis within the 6.7 mean years of follow-up; and 26% of the patients had minor postoperative complications, permanent nasal crusting being most persistent and frequent.

Cost-effectiveness of endoscopic sphenopalatine artery ligation versus nasal packing as first-line treatment for posterior epistaxis

BACKGROUND

The advent of endoscopic sphenopalatine artery ligation (ESPAL) for the control of posterior epistaxis provides an effective, low-morbidity treatment option. In the current practice algorithm, ESPAL is pursued after failure of posterior packing. Given the morbidity and limited effectiveness of posterior packing, we sought to determine the cost-effectiveness of first-line ESPAL compared to the current practice model.

METHODS

A standard decision analysis model was constructed comparing first-line ESPAL and current practice algorithms. A literature search was performed to determine event probabilities and published Medicare data largely provided cost parameters. The primary outcomes were cost of treatment and resolution of epistaxis. One-way sensitivity analysis was performed for key parameters.

RESULTS

Costs for the first-line ESPAL arm and the current practice arm were $6450 and $8246, respectively. One-way sensitivity analyses were performed for key variables including duration of packing. The baseline difference of $1796 in favor of the first-line ESPAL arm was increased to $6263 when the duration of nasal packing was increased from 3 to 5 days. Current practice was favored (cost savings of $437 per patient) if posterior packing duration was decreased from 3 to 2 days.

CONCLUSION

This study demonstrates that ESPAL is cost-saving as first-line therapy for posterior epistaxis. Given the improved effectiveness and patient comfort of ESPAL compared to posterior packing, ESPAL should be offered as an initial treatment option for medically stable patients with posterior epistaxis.

The Wexham Criteria: defining severe epistaxis to select patients requiring sphenopalatine artery ligation

This study aims to provide guidance regarding patient selection and timing of intervention with sphenopalatine artery (SPA) ligation by defining 'severe epistaxis'. An analysis of all patients undergoing SPA ligation (January 2002-2010) was performed. SPA ligation was deemed necessary if at least one of the four identified criteria was fulfilled. The same analysis was also performed on all patients admitted with epistaxis who did not undergo SPA ligation over a 6-month period. All 27 patients who underwent SPA ligation met at least one of the criteria selected. Uncontrolled epistaxis (21/27) was fulfilled most often. In comparison, only 4/71 patients admitted with epistaxis who did not undergo SPA ligation fulfilled any single criterion. All criteria were satisfied in a significantly higher number of cases in the SPA group (p < 0.001) The criteria studied proved helpful in identifying patients admitted to hospital with epistaxis who had failed conservative measures.

Management of intractable spontaneous epistaxis

BACKGROUND

Epistaxis is a common otolaryngology emergency and is often controlled with first-line interventions such as cautery, hemostatic agents, or anterior nasal packing. A subset of patients will continue to bleed and require more aggressive therapy.

METHODS

Intractable spontaneous epistaxis was traditionally managed with posterior nasal packing and prolonged hospital admission. In an effort to reduce patient morbidity and shorten hospital stay, surgical and endovascular techniques have gained popularity. A literature review was conducted.

RESULTS

Transnasal endoscopic sphenopalatine artery ligation and arterial embolization provide excellent control rates but the decision to choose one over the other can be challenging. The role of transnasal endoscopic anterior ethmoid artery ligation is unclear but may be considered in certain cases when bleeding localizes to the ethmoid region.

CONCLUSION

This article will focus on the management of intractable spontaneous epistaxis and discuss the role of endoscopic arterial ligation and embolization as it pertains to this challenging clinical scenario.

Outcomes of endoscopic sphenopalatine artery ligation for epistaxis: a five-year series from a single institution

Epistaxis is a common emergency seen by the otolaryngologist. A minority of cases require surgical intervention. Multiple surgical procedures have been tried in the past, including endoscopic ligation of the sphenopalatine artery (ELSPA), which is considered an effective surgical modality in the management of epistaxis. This study examines the outcome of 33 ELSPA procedures over a 5-year period. Three of 4 cases that were not controlled with ELSPA were successfully managed with subsequent anterior ethmoidal ligation. Failed ELSPA procedures may represent an incorrect choice of procedure rather than a failure of the procedure. High-resolution computed tomography can identify the position of the anterior ethmoidal artery; it may be possible to infer vulnerability to hemorrhage from this artery and hence target procedure selection.

Sphenopalatine artery ligation with nerve resection in patients with vasomotor rhinitis and polyposis: a prospective, randomized, double-blind investigation

CONCLUSIONS

Sphenopalatine artery ligation relieves symptoms of rhinorrhea, sneezing, and nasal itching in patients with vasomotor rhinitis associated with nasal polyps.

OBJECTIVES

Nasal polyps often arise in a setting of vasomotor rhinitis. Dysfunctions in nerve fiber activity of the sympathetic and parasympathetic systems are responsible for the accompanying symptoms of rhinorrhea, sneezing, and nasal itching. Sphenopalatine pedicle resection with autonomic denervation could potentially reduce related symptoms.

METHODS

In a prospective, double-blind setting, 60 patients with vasomotor rhinitis and bilateral nasal polyps randomly assigned to functional endoscopic surgery either with (group A) or without (group B) sphenopalatine artery ligation completed a 3-year follow-up. Preoperative and postoperative (at 1 and 3 years) evaluations included symptom score, fiberendoscopy, and active anterior rhinomanometry.

RESULTS

In both treatment groups nasal breathing had improved at 1-year and 3-year follow-up (p < 0.001), whereas an improvement in rhinorrhea (p < 0.001) and sneezing and itching (p < 0.01) was attained only in group A. The inter-group comparison showed that a statistically significant improvement in rhinorrhea and nasal itching (p = 0.002) and in sneezing (p < 0.001) was present in group A at both follow-up visits. Rhinomanometry improved in both treatment groups (p < 0.01). Inter-group comparison showed a significant difference only at the 3-year follow-up visit (p < 0.05).

Endoscopically guided chitosan nasal packing for intractable epistaxis

BACKGROUND

The purpose of this study was to evaluate the effectiveness and safety of endoscopically guided chitosan packing in controlling intractable epistaxis. A prospective case series was performed.

METHODS

This is a prospective clinical study conducted in a tertiary rhinology fellowship training hospital between January 2009 and November 2009. The study population consisted of patients with intractable epistaxis that failed to respond to traditional anterior-posterior nasal packing using either a 10-cm Pope PVA Merocel or a Rapid-Rhino. The bleeding site was identified using a nasal endoscope and controlled using a pack made of a ChitoFlex chitosan dressing wrapped around a polyvinyl acetal nasal sponge.

RESULTS

The intent-to-treat population consisted of 20 severe epistaxis subjects (8 men and 12 women) who continued to bleed despite traditional anterior-posterior nasal packing. The mean age was 67 years (±19 years). Sixteen subjects were on antiplatelets and/or anticoagulants. Eleven subjects (55%) presented with anterior epistaxis, and 7 subjects (35%) presented with posterior epistaxis. Chitosan nasal packing was performed on an outpatient basis and resulted in effective and immediate hemostasis in 19/20 subjects (95%). One subject had persistent bleeding after the first packing attempt and was successfully repacked within 30 minutes. Time to complete cessation of bleeding was 3.6 ± 2.2 minutes in the 19 subjects; the pack was removed after 48 hours, without any evidence of rebleeding or any serious side effects.

CONCLUSION

Endoscopically guided chitosan packing is a safe, effective, and well-tolerated outpatient treatment for the management of intractable epistaxis.

Endoscopic devascularisation of sphenopalatine bundle in intractable posterior epistaxis: technique, efficacy and safety

OBJECTIVE

To evaluate endoscopic cauterisation of the sphenopalatine neurovascular bundle, as treatment for intractable posterior epistaxis, with regard to efficacy, safety and post-operative sequelae.

PATIENTS AND METHODS

A prospective study reviewed 42 patients with severe posterior epistaxis who were treated with endoscopic cauterisation of the sphenopalatine neurovascular bundle, over a 17-month period.

RESULTS

Hypertension and hepatic disease were present as predisposing factors in 66.7 and 35.7 per cent of patients, respectively. Branching of the sphenopalatine artery at its foramen was present in more than 85 per cent of patients. The success rate was 100 per cent, with no recurrent epistaxis in the follow-up period. Severe nasal dryness was present in only four patients (9.5 per cent); hypoaesthesia was found in the nasal mucosa of eight patients, without any patient complaints.

CONCLUSION

Endoscopic sphenopalatine neurovascular bundle cauterisation is an effective treatment for refractory posterior epistaxis. In this study, neurovascular bundle cauterisation did not cause any neurological deficits or major complications.

[Ligation of the sphenopalatine artery in posterior epistaxis. Retrospective study of 50 patients]

OBJECTIVES

The aim of this study was to evaluate the efficacy of endoscopic ligation of the sphenopalatine artery in the treatment of severe posterior epistaxis.

METHODS

We have carried out a retrospective study on 50 patients hospitalised with posterior recurrent epistaxis, in whom posterior nasal packing was not effective. All of them underwent surgical treatment, with endoscopic ligation of the sphenopalatine artery to control the epistaxis.

RESULTS

Only seven patients had a new epistaxis after surgery. One of them is being studied for some kind of coagulopathy, another patient was controlled by ligation of the anterior ethmoidal artery and it was necessary to ligate the contralateral sphenopalatine artery in a third patient. The other four patients were controlled with posterior nasal packing and discharged two days after surgery, without any complications.

CONCLUSIONS

We believe that endoscopic ligation of the sphenopalatine artery is a safe technique, with fewer complications than other methods such as posterior packing or embolisation.

Endoscopic management of recurrent epistaxis: the experience of two metropolitan hospitals in Italy

CONCLUSION

Endoscopic cauterization of the sphenopalatine artery and anterior ethmoid artery is a first-line standard of care in managing intractable epistaxis, after the failure of previous packing. Epistaxis occurs in 12% of the population. Treatment is often based on nasal packing that could be poorly effective in the treatment of severe posterior epistaxis.

OBJECTIVE

To evaluate the effectiveness of the endoscopic approach for posterior epistaxis.

METHODS

We report the experience of endoscopic cauterization in two metropolitan hospitals in Italy: 48 patients with at least one nasal packing in the 3 weeks before hospital admission. They underwent endoscopic cauterization of the sphenopalatine artery or of the anterior ethmoid artery.

RESULTS

The patients' mean age was 58.7 years; the mean hospital stay was 2.97 days. In 42 cases (87.5%), cauterization of the sphenopalatine artery was performed, and 6 (12.5%) were subjected to anterior ethmoid artery treatment. Epistaxis control was achieved in 93% of cases; 3 patients had a recurrent nasal bleeding, and were treated with anterior nasal packing. Minor complications occurred in 27.1%. We achieved a shorter hospital stay compared with patients who underwent anteroposterior packing.

Sphenopalatine artery ligation under local anesthesia: A report of two cases and review of the literature

Epistaxis is the commonest emergency in otorhinolaryngology. Over the last decade endoscopic sphenopalatine artery (SPA) ligation has become a popular treatment option for posterior epistaxis and has been shown to be the most effective and cost-efficient definitive treatment for posterior epistaxis. SPA ligation is usually performed under general anesthesia. The majority of epistaxis patients are elderly, frail and have multiple medical conditions. These patients are therefore not always amenable to general anesthesia. In this article we describe two cases where posterior epistaxis was successfully treated with sphenopalatine artery ligation under local anesthesia and should be considered suitable for patients with severe posterior epistaxis who are not fit for a general anesthetic.

Sphenopalatine and anterior ethmoidal artery ligation for severe epistaxis

OBJECTIVES

We describe the surgical treatment of severe epistaxis and evaluate the recurrence of bleeding in a nonrandomized retrospective trial.

METHODS

We performed a retrospective study comparing bilateral endoscopic ligation of the sphenopalatine artery alone (ELSPA) and bilateral endoscopic ligation of the sphenopalatine artery with concomitant bilateral external ligation of the anterior ethmoidal artery (ELSPEA) in the management of persistent epistaxis. Clinical and hematologic information, preoperative and surgical care, and short- and long-term outcomes were analyzed. The main outcome measure was recurrence of epistaxis in the short- and long-term follow-up periods.

RESULTS

Forty-five patients were enrolled in the study. There were 20 patients in group A (ELSPA) and 25 in group B (ELSPEA). Three patients in group A and no patients in group B had long-term (more than 2 weeks after surgery) rebleeding. The difference between the two groups was not statistically significant (p > 0.05).

CONCLUSIONS

We conclude that ELSPA and ELSPEA are effective, well-tolerated, reliable procedures if performed by an experienced surgeon. Their failure can be explained by anatomic lateral nasal wall variations and perioperative technical difficulties. They can be appropriate methods to treat severe recurrent epistaxis refractory to repeated nasal packing.

Endovascular treatment of epistaxis

Epistaxis is a common condition that can be managed conservatively in most cases. When these measures, including anterior and posterior packing of the nasal cavity, are unsuccessful at controlling the bleeding, interruption of the blood supply to the sinonasal area can be performed, either by surgical ligation or by transarterial embolization. Embolization should be preceded by thorough diagnostic angiography. Aside from aiding with subsequent selective catheterization and embolization, such angiography may reveal significant anatomic anomalies, anastomoses, or an unsuspected cause of epistaxis. Taking these findings into account, the interventionalist may decide to refrain from embolization or adjust the technique to minimize the risk of adverse events, which are mostly related to inadvertent embolization of the internal carotid artery or ophthalmic artery. We present a review of the various causes of epistaxis and the treatment options, with emphasis on endovascular embolization. We also describe the protocol of our institution for endovascular management of this condition.

Endoscopic ligation of the sphenopalatine artery and the maxillary artery for the treatment of intractable posterior epistaxis

BACKGROUND

Intractable posterior epistaxis sometimes requires intensive treatment, such as surgery or embolization. Maxillary artery ligation has been widely used for the treatment of intractable posterior epistaxis. It is highly effective, but significant complications may occur, including an oroantral fistula and damage to the infraorbital nerve. Embolization is less invasive and can be performed in poor surgical candidates. However, it has more serious complications, such as facial nerve paralysis and hemiplegia. This investigation evaluates the effectiveness and complications of endoscopic ligation of the sphenopalatine or maxillary artery for the treatment of intractable posterior epistaxis.

METHODS

Between April 2003 and March 2007, 46 patients were hospitalized for the treatment of severe posterior epistaxis in our University Hospital. Thirty patients were successfully treated by anterior and/or posterior nasal packing, and five patients were treated by electrocoagulation. Endoscopic ligation was performed under general anesthesia in 11 patients (6 men and 5 women; age range, 50-80 years).

RESULTS

Eight patients underwent endoscopic ligation of the sphenopalatine artery, and three patients underwent endoscopic ligation of the maxillary artery through the middle meatus and posterior antral wall opening. There were no complications, and the patients' postoperative courses were uneventful. Recurrent epistaxis occurred in one patient on oral anticoagulants 15 months after ligation of the sphenopalatine artery, and it was successfully treated by anterior nasal packing.

CONCLUSION

Endoscopic ligation of the sphenopalatine or maxillary artery is safer than arterial embolization and is less invasive than transantral ligation of the maxillary artery. This technique appears to be a simple and highly effective surgical treatment for patients with intractable posterior epistaxis.

The nasal seromucinous glands after endoscopic sphenopalatine artery coagulation

Endoscopic coagulation of the sphenopalatine artery (SPA) is indicated in patients with recurrent or severe posterior epistaxis. The present work aimed at studying the effects of the sphenopalatine artery coagulation on the nasal seromucinous glands. The study was carried out on 30 patients who were scheduled for endoscopic SPA coagulation. All patients signed informed consents that were approved by the Committee of Medical Ethics. Minute punch biopsies were taken from the inferior turbinates, under local anesthesia, just before the procedure as well as 12 weeks and 1 year postoperatively. The biopsies were stained with hematoxylin and eosin and PAS Alcian blue. Histochemical examination was done for the activity of the succinic dehydrogenase, alkaline phosphatase and cholinesterase enzymes. Morphometric analysis as well as analysis of the histological and histochemical results showed that SPA coagulation was followed by an early decrease in the size, number and secretory activity of the nasal seromucinous glands, which was associated with decreased activity of the alkaline phosphatase enzyme in the endothelial cells of the nasal blood vessels and decreased activity of the cholinesterase enzyme in the cholinergic nerve fibers. These changes, however, were temporary and reversible since examination of the late postoperative biopsies, at 1 year, showed normalization of the number, appearance, and histochemical activity of the glandular acini as well as the surrounding blood vessels and cholinergic nerve fibers.

Severe posterior epistaxis-endoscopic surgical anatomy

OBJECTIVE

To describe the anatomy of the sphenopalatine foramen (SPF) region and possible anatomical variations.

STUDY DESIGN

Prospective study accomplished from September, 2006, to January, 2007.

METHODS

The sphenopalatine foramen (SPF) of 61 cadavers were carefully dissected. Presence of the ethmoidal crest, location of sphenopalatine and accessory foramens, and the number of arterial branches emerging through foramens were observed. Data were analyzed in relation to gender, racial group, and symmetry of the cadaver. Prediction of the presence of accessory foramen was evaluated.

RESULTS

Mixed race cadavers prevailed in 122 nasal fossae dissected (75% males). Ethmoidal crest was present in 100% of the cadavers, being anterior to the SPF in 98.4% of the cases. The most frequent SPF location was the transition of the middle and superior meatus (86.9%). Mean distance from the SPF and accessory foramen to anterior nasal spine was 6.6 cm and 6.7 cm, respectively. Accessory foramen was present in 9.83% of the cases. A single arterial stem emerged through the SPF in 67.2% of the cases, and 100% through accessory foramens. The prevalence analyses showed no differences that were statistically significant (P > 0.05) between gender and racial group. The symmetry analyses showed a strong conformity (P < 0.01) between nasal fossae in relation to the SPF location. There was no statistically significant conformity between nasal fossae and accessory foramen (P = 0.53). None of the variables of interest presents any statistically significant (P > 0.05) association with the presence of the accessory foramen.

CONCLUSIONS

There are anatomical variations in the lateral nose wall that should be considered for successful endoscopic surgical treatment of severe epistaxis.

Endoscopic anatomy of the pterygopalatine fossa

BACKGROUND

The pterygopalatine fossa can be involved with a variety of infectious and neoplastic processes. This region can be entered endoscopically, but endoscopic landmarks to localize the neurovascular structures in the pterygopalatine fossa have not yet been reported.

OBJECTIVES

The purpose of this study is to describe the location of the neurovascular structures in the pterygopalatine fossa in relation to consistent intranasal landmarks.

METHODS

Endoscopic dissections of cadaveric heads were performed. The locations of neurovascular structures in the region were defined.

RESULTS

The sphenopalatine foramen (SPF) served as the primary intranasal landmark to the pterygopalatine fossa (PPF). Mean distances from the SPF were measured with the following results: SPF to sphenopalatine ganglion (SPG), 4 mm medially and 6 mm laterally; SPF to foramen rotundum (FR), 7 mm; and SPF to vidian canal (VC), 2 mm. The internal maxillary artery followed an irregular and inconsistent course, making it difficult to define a reliable landmark for its location in the fossa.

CONCLUSION

Entering the PPF inferior to the horizontal plane of the SPF along a vertical line drawn inferiorly from the infraorbital canal will avoid injury to the major neural structures in the fossa. Because of the inconsistent course and location of the internal maxillary artery, this structure may be at risk no matter where the fossa is entered. These landmarks will allow the surgeon to enter the PPF with more accuracy and less patient morbidity.

Resection of a recurrent paraganglioma via an endoscopic transnasal approach to the jugular fossa

OBJECTIVE

To present a novel endoscopic, transnasal approach to a recurrent paraganglioma of the jugular fossa (glomus jugulare).

STUDY DESIGN

Case report and review of the literature.

SETTING

The study was carried out at the University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, U.S.A.

PATIENT

A 64-year-old woman presented to the University of Pittsburgh Medical Center with a 9-month history of left otalgia, occasional vertigo, facial pain, and recurrent epistaxis. She had undergone two previous procedures over the past 35 years for a glomus tympanicum. Physical examination revealed a mass in the left nasopharynx originating from the eustachian tube. A computed tomographic scan revealed an expansive mass in the left jugular foramen extending into the posterior parapharyngeal space suggestive of a large jugular paraganglioma.

INTERVENTION

The patient underwent preoperative embolization of the paraganglioma. An endoscopic, transnasal approach along the eustachian tube, the ascending parapharyngeal carotid artery, and into the jugular fossa was used to remove the tumor. Intraoperative image guidance assisted in the identification of key anatomic landmarks.

RESULTS

Postoperative magnetic resonance imaging revealed a thin rim of enhancement at the posterior aspect of the jugular fossa consistent with residual tumor. The patient was discharged to home on postoperative Day 1 in stable condition. There have been no complications with 4 months of follow-up, and the left facial paralysis secondary to preoperative embolization has resolved.

CONCLUSION

We report the successful subtotal resection of a recurrent paraganglioma via a novel endoscopic, transnasal, transclival, transpetrous approach with image guidance. This approach allowed the near-total resection of a recurrent glomus jugulare with minimal surgical morbidity. Technological advances and surgical experience with nasal endoscopy and image guidance allow minimally invasive surgical management of select extracranial lesions of the lateral cranial base.

[Practical aspects regarding endoscopic treatment for epistaxis]

INTRODUCTION

A prospective study is presented to evaluate some practical and financial aspects regarding surgical endoscopic ligation or cauterization of sphenopalatine (SP) and anterior ethmoidal (AE) arteries performed to control posterior nasal bleeding.

PATIENTS AND METHODS

35 patients admitted at the ENT ward between 2004 and 2006 were included in the study, and distributed into two groups depending on the protocol applied in each case. Until March 2005 the surgery was performed if there was failure or insecurity of the posterior packing, and since that date a substitutive surgical protocol (not including posterior packing) was applied.

RESULTS

82.9% of the patients were male, with a mean age of 55.74 years and a left bleeding in a 60% of the cases. Ligature/cauterization was performed on SP in 28 (80%) patients, on AE in 4 (11.4%), and on both arteries in 3 cases (8.6%). 38.7% of the SP approach only one sphenopalatine foramen was observed, through which an only branch of the artery passed; 42% of the cases two branches passed through an only foramen, and in 19.3% two or more branches were present, breaking into the nose through two or more independent clefts. AE was intradural in 3 cases, intranasal attached to the cranial base in other 3 and intranasal detached to the cranial base in 1 patient. Besides, highly significant differences were found between the two protocols, observing a mean reduction of hospital stay of 3.1 days, which throws up savings of 939.3 euros per patient.

DISCUSSION AND CONCLUSIONS

Surgical treatment for epistaxis has proved to be effective (91.2% in our experience) and safe, determining an important reduction in hospital stay and avoiding the morbility of posterior packing. Accurate knowledge of the anatomy of the arteries implied and specific actuation upon the correct bleeding territory are essential to perform this surgery.

The anatomy of the sphenopalatine artery for the endoscopic sinus surgeon

BACKGROUND

This study was performed to determine the variations in the branching pattern of the sphenopalatine artery medial to the crista ethmoidalis. Seventy-seven cadaver head sides that had been sectioned sagittally in the midline with their septum removed were used after injecting pink latex to highlight the arterial vessels.

METHODS

The mucosa from the middle meatus from the level of the basal lamella was removed until the artery and its branches were seen and then was examined under the microscope to identify the position of the arterial branches.

RESULTS

The sphenopalatine artery and its branches were identified in 75 specimens. Of these 75 specimens, 73 (97%) had 2 or more branches medial to the crista ethmoidalis, 49 (67%) had 3 or more branches, 26 (35%) had 4 or more branches, and 1 specimen had 10 branches. In two specimens the artery presented as a single trunk.

CONCLUSION

The sphenopalatine artery normally starts to branch lateral to the crista ethmoidalis and these branches vary widely. It is important that the surgeon who undertakes ligation or cautery of the artery is aware of these variations, otherwise they may overlook some of the branches. With an endoscopic approach, removal of the crista ethmoidalis helps visualize these branches.
