Online training for hearing implant surgery : A new approach to otological training.

OBJECTIVE: Education in microsurgery of the ear includes staged training to allow for mastering of the complex microsurgical procedures, particularly in the context of middle ear reconstruction and cochlear implantation. Traditional surgical training includes temporal bone preparations by cadaver dissection and supervised operating room practice. As these on-site trainings are limited, there is a need to broaden education facilities in an on-line format. Therefore, a first basic on-line training for otosurgery was developed. MATERIALS AND METHODS: The system consists of an artificial temporal bone model together with a set of basic surgical instruments and implant dummies. As an essential part of the training kit, a high-resolution camera set is included that allows for connection to a video streaming platform and enables remote supervision of the trainees' surgical steps by experienced otological surgeons. In addition, a pre-learning platform covering temporal bone anatomy and instrumentation and pre-recorded lectures and instructional videos has been developed to allow trainees to review and reinforce their understanding before hands-on practice. RESULTS: Over the three courses held to date, 28 participants with varying levels of prior surgical experience took part in this otological surgical training program. The immediate feedback of the participants was evaluated by means of a questionnaire. On this basis, the high value of the program became apparent and specific areas could by identified where further refinements could lead to an even more robust training experience. CONCLUSION: The presented program of an otosurgical online training allows for basal education in practical exercises on a remote system. In this way, trainees who have no direct access to on-site instruction facilities in ear surgery now have the chance to start their otosurgical training in an educational setting adapted to modern technologies.

[Increasing incidence of mastoidectomies in children : Result of reduced antibiotic therapy or late COVID-19 sequela?] / Steigende Inzidenzen bei Mastoidektomien im Kindesalter : Folge geringeren Antibiotikaeinsatzes oder eine COVID-19-Spätfolge?

BACKGROUND: An increasing number of pediatric patients with mastoiditis and a consequent increase in mastoidectomy rates was noted in 2022 and 2023. OBJECTIVE: This study aimed to analyze the increase in the number of children presenting with mastoiditis and subsequent mastoidectomy, to assess correlations with prior antibiotic treatment or COVID-19 infection, and to provide an overview of involved pathogens, treatment, and disease course. MATERIALS AND METHODS: A retrospective analysis of all patients with mastoidectomy since 2012 was conducted. Data collected comprised type and duration symptoms, prior antibiotic therapy, diagnostic tests and disease course, causal pathogens, length of hospitalization, and complications. RESULTS: A highly significant increase in mastoidectomies in children could be demonstrated from 2022. Neither the pathogens involved nor the course of disease or complications showed differences. An increase in the number of patients with prior outpatient antibiotic therapy could be shown. About a half of the patients becoming ill after fall 2022 had a positive history of COVID. Hyperplasia of adenoid tissue was a far less frequent causal mechanism than in the years before COVID. CONCLUSION: No clear correlation with reduced outpatient antibiotic therapy could be found. Whether there exists an association with prior COVID infection cannot be judged at this time, due to the high number of asymptomatic and therefore unknown COVID infections.

An unusual presentation: temporomandibular tissue herniation through congenital foramen of Huschke.

BACKGROUND: The herniation of temporomandibular tissue through the foramen of Huschke into the external auditory canal is a rare clinical anomaly. This paper describes one such case and provides an overview of the relevant literature. This paper elaborates upon the aetiology, clinical assessment, management and associated complications. CASE REPORT: A 54-year-old woman presented with a 3-month history of right ear pain and a polypoid lesion in her right ear canal. This lesion expanded during a Valsalva manoeuvre, and imaging demonstrated a defect in the antero-superior aspect of the canal with herniation of soft tissue. The patient was managed conservatively as the symptoms resided. CONCLUSION: Ear canal lesions that protrude or change in size with a Valsalva manoeuvre could be due to a persistent foramen of Huschke. In symptomatic cases needing surgical intervention, a variety of materials may be used to close the defect. Titanium mesh, with or without cartilage overlay, appears to be the most popular choice.

Quantifying the effect of shoulder size on operation duration: an analysis of stapes surgery outcomes.

OBJECTIVE: To investigate the effect of body mass index on hearing outcomes, operative time and complication rates following stapes surgery. METHOD: This is a five-year retrospective review of 402 charts from a single tertiary otology referral centre from 2015 to 2020. RESULTS: When the patient's shoulder was adjacent to the surgeon's dominant hand, the average operative time of 40 minutes increased to 70 minutes because of a significant positive association between higher body mass index and longer operative times (normal body mass index group (<25 kg/m2) r = 0.273, p = 0.032; overweight body mass index group (25-30 kg/m2) r = 0.265, p = 0.019). Operative times were not significantly longer upon comparison of low and high body mass index groups without stratification by laterality (54.9 ± 19.6 minutes vs 57.8 ± 19.2 minutes, p = 0.127). CONCLUSION: There is a clinically significant relationship between body mass index and operating times. This may be due to access limitations imposed by shoulder size.

Total Transcanal Endoscopic Ear Surgery for Cholesteatoma.

Objective: This study aimed to evaluate the outcomes of total transcanal endoscopic cholesteatoma surgery. Methods: Twenty-seven cholesteatoma patients that had undergone transcanal endoscopic ear surgery (TEES) were included in the study. Age, sex, operation date of patients, operated side, need for ossiculoplasty, graft material, and surgical technique were recorded. All patients were evaluated through otoscopic, endoscopic, and audiological examinations and followed up for at least five months after surgery. All patients were staged using the European Academy of Otology and Neurotology/Japan Otological Society (EAONO/JOS) Staging System on Middle Ear Cholesteatoma. Results: Mean age of the patients was 36.4 years (range, 4-67 years). According to the EAONO/JOS Staging System, 11 patients were stage 1, while 11 were stage 2, and five were stage 3. Two had lateral semicircular canal defect, one had facial canal dehiscence, and one had oval window defect. The average follow-up period was 19 months (range, 5-41 months), during which two patients experienced retraction pocket and hearing loss and one patient had perforation. One patient underwent revision surgery during follow-up and no recurrence or residual cholesteatoma was observed. The preoperative and postoperative air-bone gaps were 25.14±13.93 dB and 22.22±12.64 dB with no significant difference. Conclusion: TEES is a minimally invasive and safe procedure with low complication and recurrence rates. As with all surgical procedures, experience is essential, and as experience increases, the capability to perform endoscopic otologic surgery on more complex cases may become possible.

[Revision surgery after stapedectomy]. / Revisionsoperationen nach Stapesplastik.

Revision stapes surgery is considered to be significantly more demanding than primary stapes surgery, both in terms of the indication and the surgical approach. This article reviews common indications for revision after stapedectomy as well as the surgical approaches and intraoperative findings. A distinction is made between revision surgeries, which are usually carried out because of conductive hearing loss a long time after stapes surgery, and acute or subacute revisions that become necessary in the immediate postoperative course. With the shortening of postoperative observation times under inpatient conditions as a result of increasing economization and the associated shift of the immediate postoperative phase to the outpatient setting, the recognition of postoperative irregularities is also becoming increasingly important for otorhinolaryngologists in private practice, even if they do not perform these highly specialized interventions themselves.

PROPELLER diffusion weighted imaging for diagnosis of cholesteatoma in comparison with surgical and histopathological results: emphasis on false positivity and false negativity.

PURPOSE: To investigate the role of non-echo planar diffusion weighted imaging (DWI) using "periodically rotated overlapping parallel lines with enhanced reconstruction" (PROPELLER) sequence for the diagnosis of cholesteatoma compared to surgical and histopathological results in an attempt to determine the factors causing false negative and false positive diagnoses. METHODS: Patients who had PROPELLER DWI before ear surgery were retrospectively reviewed. The presence of a lesion with diffusion restriction on PROPELLER DWI was accepted as positive for cholesteatoma, and the results were compared to the intraoperative and histopathological findings. RESULTS: A total of 112 ears in 109 patients were reviewed. On PROPELLER DWI, a lesion with diffusion restriction was found in 101 (90.2%) ears, while in 11 (9.8%) of the patients, no diffusion restriction was found. Surgery and histopathological analysis revealed a cholesteatoma in 100 (89.3%) ears, while in 12 (10.7%) ears, no cholesteatoma was found surgically. There were 96 (85.7%) true positives, 7 (6.2%) true negatives, 5 (4.5%) false positives and 4 (3.6%) false negatives. The accuracy, sensitivity, specificity, positive predictive and negative predictive values of non-echo planar DWI were calculated to be 91.96%, 96%, 58.33%, 95.05%, and 63.64%, respectively. CONCLUSION: Non-echo planar DWI using PROPELLER sequence has high accuracy, sensitivity and positive predictive value and can be used for the detection of cholesteatoma. The external auditory canal, postoperative ears and small lesions should be evaluated with caution to avoid false results.

Improved Bone Conduction Hearing After Middle Ear Surgery: Investigation of the Improvement Mechanism.

OBJECTIVES: When performing middle ear operations, such as ossiculoplasty or stapes surgery, patients and surgeons expect an improvement in air conduction (AC) hearing, but generally not in bone conduction (BC). However, BC improvement has often been observed after surgery, and the present study investigated this phenomenon. METHODS: We reviewed the preoperative and postoperative surgical outcomes of 583 patients who underwent middle ear surgery. BC improvement was defined as a BC threshold decrease of >15 dB at two or more frequencies. Subjects in group A underwent staged ossiculoplasty after canal wall up mastoidectomy (CWUM), group B underwent staged ossiculoplasty after canal wall down mastoidectomy (CWDM), group C underwent ossiculoplasty only (thus, they had no prior history of CWUM or CWDM), and group D received stapes surgery. We created a hypothetical circuit model to explain this phenomenon. RESULTS: BC improvement was detected in 12.8% of group A, 9.1% of group B, and 8.5% of group C. The improvement was more pronounced in group D (27.0%). A larger gain in AC hearing was weakly correlated with greater BC improvement (Pearson's r=0.395 in group A, P<0.001; r=0.375 in group B, P<0.001; r=0.296 in group C, P<0.001; r=0.422 in group D, P=0.009). Notably, patients with otosclerosis even experienced postoperative BC improvements as large as 10.0 dB, from a mean value of 30.3 dB (standard error [SE], 3.2) preoperatively to 20.3 dB (SE, 3.2) postoperatively, at 1,000 Hz, as well as an improvement of 9.2 dB at 2,000 Hz, from 37.8 dB (SE, 2.6) to 28.6 dB (SE, 3.1). CONCLUSION: BC improvement may be explained by a hypothetical circuit model applying the third window theory. Surgeons should keep in mind the possibility of BC improvement when making a management plan.

A novel imaging scoring method for identifying facial canal dehiscence: an ultra-high-resolution CT study.

OBJECTIVES: Facial canal dehiscence (FCD), typically found in the tympanic segment, is a risk factor for facial nerve injury. An imaging scoring method was proposed to identify FCD based on ultra-high-resolution CT. METHODS: Forty patients (21 females and 19 males, mean age 44.3 ± 17.4 years), whose tympanic facial canal (FC) was examined during otological surgery, were divided into the FCD group (n = 29) and the control group (n = 11) based on surgical findings. Imaging appearance of tympanic FC was scored 0-3: 0 = no evident bony covering, 1 = discontinuous bony covering with linear deficiency, 2 = discontinuous bony covering with dotted deficiency, and 3 = continuous bony covering. Both lateral and inferior walls were assigned a score as LFCD and IFCD, respectively. An FCD score was calculated as LFCD + IFCD. The diagnostic value of the FCD score was tested using the ROC curve. RESULTS: The inter-observer agreement was moderate for the lateral wall (Cohen's κ coefficient 0.416, 95% CI 0.193-0.639), and good for the inferior wall (Cohen's κ coefficient 0.702, 95% CI 0.516-0.888). In the FCD group, the most common appearance for both walls was discontinuous bony covering with linear deficiency (LFCD = 1, 22/29, 75.9%; IFCD = 1, 15/29, 51.7%). An FCD score of less than 4 was associated with high sensitivity (0.82) and specificity (0.93) for identifying FCD, with an AUC of 0.928. CONCLUSIONS: Using the proposed scoring method, FCD score < 4 could identify FCD of the tympanic segment with high concordance with surgical findings. KEY POINTS: • Imaging appearance of the tympanic facial canal (FC) is divided into four types based on ultra-high-resolution CT images. • The most common appearance of FC with facial canal dehiscence (FCD) is discontinuous bony covering with linear deficiency. • An FCD score, consisting of scores of the lateral and inferior walls, less than 4 is highly indicative of FCD.

Focal meato-mastoid fistula closure using bony sigmoid sinus plate.

OBJECTIVE: This study aimed to analyse the effectiveness of using the bony sigmoid sinus plate for repair of meato-mastoid fistulae. METHOD: A retrospective study of all cases between January 2013 and December 2019 at our secondary-tertiary centre was conducted. Inclusion criteria for study were: (1) cases with focal meato-mastoid fistulae and (2) focal meato-mastoid fistulae that were repaired by using bony sigmoid sinus plate using the bony sigmoid sinus plate technique. There were 13 cases that fulfilled these criteria. RESULTS: The outcome of the repair of meato-mastoid fistulae with bony sigmoid sinus plate was very encouraging. All 13 cases did well. Two patients had delayed epithelialisation at 9 and 12 months after surgery. CONCLUSION: The technique of repairing meato-mastoid fistulae by using bony sigmoid sinus plate is simple, repeatable and provides effective physiological reconstruction of the posterior canal wall. Bony sigmoid sinus plate is easily and locally available in all cases undergoing cortical mastoidectomy. This plate of bone has a curvature, consistency and structure that match well with that of the posterior or superior canal wall. In addition, this technique is cost-effective with good patient compliance.

Recessive Dystrophic Epidermolysis Bullosa: Rare Bilateral External Auditory Canal Stenosis and Surgical Treatment.

Epidermolysis bullosa (EB) is a family of rare genetic disorders affecting the skin and mucous membranes, causing blisters and lesions. Its treatment is based on the prevention of traumatic events that could favor the onset of blisters as well as careful wound care. New therapies, including gene therapy, are under investigation. In the case described here, a rare localization of EB at the level of the ear canal is described. To our knowledge, no surgical option for treatment has previously been described in the literature. The clinical features observed and the therapeutic modalities adopted are presented and discussed. A 56-year-old female patient came to our attention for bilateral progressive hearing loss. The patient was suffering from Dystrophic EB. Surgical correction of the stenosis through a retroauricular approach was planned, with the simultaneous reconstruction of the right external auditory canal using the canaloplasty technique combined with Thiersch skin grafting. The case we report here is, to our knowledge, the second describing the surgical treatment of ear canal stenosis secondary to EB. As a result of surgical correction of the stenosis, the ear regained its physiological function and there was an improvement in hearing. In the subsequent post-operative controls, there was no recurrence of the disease, from which the patient is still free 36 months after surgery. Although conservative treatment is a solid choice, our experience seems to indicate that the surgical option allows better management of the Dystrophic EB in the external auditory canal.

Subtotal Petrosectomy and Cochlear Implantation in Children With Chronic Suppurative Otitis Media: A Single Institutional Experience.

BACKGROUND AND OBJECTIVES: Chronic suppurative otitis media (CSOM) with or without cholesteatoma is a frequent chronic inflammatory condition in children, which may lead to severe hearing loss that affects speech development. Treatment of recurrent CSOM associated with unserviceable hearing requires a specialized approach with regard to disease eradication and hearing rehabilitation. In this study, we investigated the advantages of subtotal petrosectomy (SP) combined with cochlear implantation (CI) in children with CSOM associated with unserviceable hearing and describe our experience with regard to the efficacy of this method, together with a literature review. SUBJECTS AND METHODS: SP with sequential or simultaneous CI was performed in three children (four ears), and postoperative audiometric data were recorded. RESULTS: The study included two male and one female patient. Mean age at the time of SP was 10.75 years (7-13 years). Sequential implantation was performed in three ears. Facial nerve palsy occurred after SP in one patient. The latest word recognition scores of Cases 1, 2, and 3 were 80% (at 60 dB), 75% (at 60 dB), and 70% (at 50 dB) and 90% (at 50 dB), respectively. CONCLUSIONS: SP with CI may be safe and reliable in children with CSOM associated with unserviceable hearing.

Superior semi-circular canal dehiscence syndrome: quantifying the effectiveness of treatment from the patient's perspective.

BACKGROUND: Superior semi-circular canal dehiscence syndrome is a disorder characterised by auditory and vestibular symptoms that can significantly impact quality of life, and yet it has no disease-specific quality of life instrument. METHOD: Thirty-six patients who underwent transmastoid superior semicircular canal resurfacing and plugging were included from an initial cohort of 60 surgically managed patients. A sub-cohort of 19 consecutive patients completed validated symptom and quality of life questionnaires before and after surgery. Of the 36 patients, 31 participated in a telephone semi-structured interview post-operatively. RESULTS: Following surgery, there was a statistically significant improvement in autophony index score (p = 0.02), symptom severity score (p < 0.001) and sound hypersensitivity (p = 0.01). Thematic analysis of telephone interviews suggested three main symptom themes: auditory hypersensitivity, dysequilibrium, headache and concentration difficulties. Dysequilibrium was found to persist post-operatively. CONCLUSION: Surgery improves overall symptoms and quality of life. However, important symptom themes may be overlooked using the outcome measures that are currently available. A unified disease-specific outcome measure is urgently required to better understand the impact of symptoms and measure treatment effects.

Audiological characteristics and effect of endoscopic surgery for simple congenital malformation of ossicular chain.

OBJECTIVE: To analyze the audiological characteristics and surgical results in patients undergoing surgery for simple congenital ossicular chain malformation, and the effect of endoscopic surgery. METHODS: A retrospective review was performed on 86 patients who underwent surgery for the congenital malformation of the ossicular chain. Clinical characteristics and audiometric data were analyzed. Fifty-eight patients had detailed postoperative data, and the preoperative and postoperative audiometric results were compared. The subjects were further divided into endoscopic and microscopic groups, and their surgical effects were examined. RESULTS: The preoperative audiometry results in the low-frequency group were worse than those in the high-frequency group (P < 0.05). A postoperative air-bone gap closure to 20 dB or less was achieved in 73.33% of the 60 ears of patients postoperatively. The postoperative air conduction and air-bone gap were significantly better than the preoperative ones (P < 0.05), and the improvement effect was the best in class III patients (P < 0.05). Postoperative hearing had no significant differences between the endoscopic and microscopic groups. However, endoscopic surgery also was more advantageous in terms of operating time (P < 0.05). CONCLUSIONS: Preoperative pure tone audiometric results showed moderate or moderate-severe hearing loss, especially in the low-frequency area. The reconstruction of the auditory ossicle chain can achieve satisfactory results, especially in class III patients. Endoscopic and microscopic surgery in the treatment of simple congenital ossicular chain malformations can effectively improve postoperative hearing.

Validation of the novel Deep Reality Viewer (DRV) 3D digital stereo viewer in otology surgery.

PURPOSE: Magnification with accurate optic reproduction of the surgical field is essential in otology surgery, but current technologies are subject to specific disadvantages. This study aims to evaluate a novel 3D digital stereo viewer, the Deep Reality Viewer (DRV), in otology surgery, in comparison to both a 2D monitor and the gold standard of microscopy. METHODS: In this prospective clinical research study, ENT consultants and trainees evaluated visual and practical applications of the DRV. In visual assessment, participants (n = 11) viewed pre-recorded in vivo mastoid exploration displayed on a 2D monitor and the DRV screen. In practical assessment, participants (n = 9) performed otology surgical tasks on a cadaveric human head using both the microscope and DRV. Face, task-specific (TSV) and global content (GCV) outcomes were assessed using 5-point Likert scale questionnaires. Construct validity was assessed separately. RESULTS: The DRV achieved the pre-determined validation threshold of 4 for all validation parameters in both visual and practical assessment. The DRV significantly outperformed the 2D monitor in fourteen of 16 parameters. In comparison to microscopy, there was no significant difference in 13 of 16 parameters, with the DRV significantly outperforming in the remaining 3: defining anatomy (GCV), assessing middle ear anatomy (TSV) and overall TSV. Construct validity was not demonstrated for either technology. CONCLUSION: The DRV achieved the validation threshold for all parameters, and outperformed the 2D monitor and microscopy in several parameters. This validates the DRV for performing otological procedures, and suggests that it would be a useful alternative to the gold standard of microscopy in otology surgery. LEVEL OF EVIDENCE: N/A.

Determinants influencing cholesteatoma recurrence in daily practice: a retrospective analysis.

BACKGROUND: Cholesteatoma is a benign but destructive epithelial lesion in the middle ear and/or mastoid. It is hard to translate data from previous research to daily clinical practice. In this study, factors influencing recurrence rates in daily clinical practice were identified. METHOD: The study included 67 patients who were treated for a cholesteatoma with combined approach tympanoplasty. The average follow-up time was 35 months. RESULTS: The recurrence rate was 23.3 per cent in adults and 45.5 per cent in children. Predictors of recurrence were younger age and a low tegmen. A cholesteatoma in a child and the simultaneous presence of a low tegmen led to recurrence in 82.8 per cent of the patients. CONCLUSION: Patients - especially children - with a low tegmen have an increased risk of recurrence. It is recommended that ENT surgeons be aware of recurrence in children, particularly in the case of a low tegmen.

[Low-grade (polymorphous) adenocarcinoma of the middle ear mimicking a jugulotympanic paraganglioma. German version]. / (Polymorphes) Low-Grade-Adenokarzinom des Mittelohrs als Imitator eines jugulotympanalen Paraganglioms.

A 64-year-old female patient presented with otalgia and hearing loss in the right ear. On otoscopy, the right tympanic membrane was highly vascularized and bulged into the anteroinferior quadrant. High-resolution computed tomography revealed an osteolytic lesion with occupation of the hypotympanum extending into the petrous apex and right parapharyngeal space as well as infiltration of the wall of the right internal carotid artery. MRI strengthened the suspicion of a jugulotympanic paraganglioma. The biopsy material obtained through exploratory tympanotomy was assessed as a low-grade polymorphic adenocarcinoma. The tumor was treated with definitive chemoradiotherapy. Posttherapeutic imaging after 4 months did not show any evidence of tumor progression.

Automated summative feedback improves performance and retention in simulation training of mastoidectomy: a randomised controlled trial.

OBJECTIVE: This study aimed to investigate the effects of automated metrics-based summative feedback on performance, retention and cognitive load in distributed virtual reality simulation training of mastoidectomy. METHOD: Twenty-four medical students were randomised in two groups and performed 15 mastoidectomies on a distributed virtual reality simulator as practice. The intervention group received additional summative metrics-based feedback; the control group followed standard instructions. Two to three months after training, participants performed a retention test without learning supports. RESULTS: The intervention group had a better final-product score (mean difference = 1.0 points; p = 0.001) and metrics-based score (mean difference = 12.7; p < 0.001). At retention, the metrics-based score for the intervention group remained superior (mean difference = 6.9 per cent; p = 0.02). Also at the retention, cognitive load was higher in the intervention group (mean difference = 10.0 per cent; p < 0.001). CONCLUSION: Summative metrics-based feedback improved performance and lead to a safer and faster performance compared with standard instructions and seems a valuable educational tool in the early acquisition of temporal bone skills.

Laceration of Aberrant Internal Carotid Artery Following Myringotomy: A Case Report and Review of Literature.

INTRODUCTION: The presence of an aberrant internal carotid artery (ICA) in the middle ear is rare. Patients may be asymptomatic or complain of conductive hearing loss, otalgia, pulsatile tinnitus, or aural fullness. Otoscopic exam findings can include a pulsating erythematous lesion on the tympanic membrane (TM). It may be misdiagnosed as a glomus tumor, hemangioma, or serous otitis media, or go unrecognized until surgical exploration. Early recognition is important as intraoperative discovery carries risk of iatrogenic injury, hemorrhage and subsequent neurologic sequelae. Prevention requires adequate preoperative suspicion and can be confirmed with radiologic examination via computed tomography (CT) scan or magnetic resonance angiography (MRA). Management of iatrogenic injury of an aberrant ICA can include packing, vessel embolization and/or surgical ligation. PATIENT CASE: We report the case of an aberrant ICA injury in a pediatric patient undergoing a myringotomy with tube placement, who sustained neurologic deficits that eventually resolved following treatment with packing and coil embolization. DISCUSSION AND CONCLUSIONS: An aberrant ICA can cause life-threatening complications without prior diagnosis in a routine myringotomy. Suspicious exam findings should prompt temporal bone CT to rule out aberrant ICA or other vascular pathology of the middle ear prior to surgery. In the case of iatrogenic injury of an aberrant ICA, there is no consensus in existing literature on optimal management. We reviewed 37 studies to compare therapeutic options and subsequent outcomes. Though complications are rare regardless of management, cases in which solely packing was utilized demonstrated an increased incidence of hemiparesis, aphasia, hearing loss, re-bleeding, and delayed pseudoaneurysm, as compared to an approach coupling packing with embolization or ligation, both of which have comparable outcomes.
