Exclusive endoscopic tympanoplasty efficacy in the treatment of cholesteatoma without mastoid involvement.

PURPOSE: The purpose of this study is to determine the recurrence rate of cholesteatoma in patients who have undergone exclusive endoscopic tympanoplasty at our tertiary referral institution. A secondary objective is to analyze different clinical aspects that could be considered risk factors for recurrence to establish if it is possible to determine when a second-look procedure is indicated instead of a clinical follow-up. METHODS: A retrospective study was performed on patients who had undergone exclusive endoscopic tympanoplasty for cholesteatoma in the last eight years and who were followed up for at least one year. The efficacy of the treatment performed only with the exclusive endoscopic technique was analyzed. Then, the anamnestic and intraoperative data were studied to identify possible factors that could increase the risk of recurrence. RESULTS: The recurrence rate (14.5%) in patients (164) who underwent primary surgery with the exclusive endoscopic technique between January 2014 and January 2022 was similar to that in patients who underwent the microscopic technique with mastoidectomy in literature. In addition, we analyzed several clinical factors such as age, ossicular chain erosion, extension and localization of the cholesteatoma finding that only the last one could potentially be a risk factor for recurrence in this selected population. CONCLUSION: Exclusive endoscopic tympanoplasty has been shown to be effective in removing cholesteatoma in patients without evidence of mastoid involvement, with recurrence rates comparable to traditional microscopic technique and a minimally invasive approach, even considering the patient's age, ossicular chain erosion and extension of the disease.

Personal experience with the remote check telehealth in cochlear implant users: from COVID-19 emergency to routine service.

PURPOSE: To critically illustrate the personal experience with using the "Remote Check" application which remotely monitors the hearing rehabilitation level of cochlear implant users at home and further allows clinicians to schedule in-clinic sessions according to the patients' needs. METHODS: 12-month prospective study. Eighty adult cochlear implant users (females n = 37, males n = 43; age range 20-77 years) with ≥ 36 months of cochlear implant experience and ≥ 12 months of stable auditory and speech recognition level volunteered for this 12-month long prospective study. For each patient, at the beginning of the study during the in-clinic session to assess the stable aided hearing thresholds and the cochlear implant integrity and patient's usage, the "Remote Check" assessment baseline values were obtained. "Remote Check" outcomes were collected at different times in the subsequent at-home sessions, to identify the patients that had to reach the Center. Chi-square test has been used for statistical analysis of the comparison of the "Remote Check" outcomes and in-clinic session results. RESULTS: "Remote Check" application outcomes demonstrated minimal or no differences between all sessions. The at-home Remote Check application reached the same clinical outcomes as the in-clinic sessions in 79 out 80 of participants (99%) with high statistical significance (p < 0.05). CONCLUSIONS: "Remote Check" application supported hearing monitoring in cochlear implant users that were not able to attend the in-clinic review during COVID-19 pandemic time. This study demonstrates that the application can be a useful routine tool also for clinical follow-up of cochlear implant users with stable aided hearing.

Transcanal infrapromontorial approach for internal auditory canal surgery and cochlear implantation.

OBJECTIVE: To demonstrate the feasibility of a transcanal infrapromontorial approach for vestibular schwannoma surgery through an anatomical dissection study and the description of a clinical case. METHODS: A microscopic and endoscopic dissection of cadaveric heads was undertaken through a transcanal infrapromontorial approach to the internal auditory canal (IAC), preserving the cochlea and the cochlear nerve. Description of the anatomy and surgical steps is reported as well as presentation of a clinical case in which a transcanal infrapromontorial approach was performed. RESULTS: In all of the cadaveric dissections, a transcanal infrapromontorial route with near total cochlea preservation was performed, removing only the most posterior portion of the basal turn of the cochlea. The IAC was opened through removal of "cochlear-vestibular bone". At the end of the dissection a cochlear implant array was placed. A transcanal infrapromontorial approach was also performed in a patient to allow a concurrent cochlear implant placement, with good postoperative results. CONCLUSION: The transcanal infrapromontorial approach permits the preservation of the cochlea and the cochlear nerve. This approach may be considered as an option in case of a small intracanalicular schwannoma removal (< 0.5 cm cerebellopontine angle spread), when concurrent cochlear implantation is indicated.

Endoscopic stapedotomy: safety and audiological results in 150 patients.

OBJECTIVE: The most widely accepted treatment for otosclerosis is currently microscopic stapes surgery under either local or general anesthesia. The aim of the study is to describe the surgical steps in endoscopic stapes surgery and to evaluate the audiologic and surgical outcomes. MATERIALS AND METHODS: All patients who underwent exclusive endoscopic stapes surgery or revision surgery for previous stapedotomy between November 2014 and September 2018 were enrolled in this study. Demographic data, surgical information, preoperative and postoperative pure tone averages and air bone gaps, intraoperative and postoperative complications and follow-up data were summarized and gathered in a database for further consideration and analysis. RESULTS: In the period examined, 181 stapes surgical procedures were performed and out of these 150 met the inclusion criteria. There were no cases of major intraoperative complications. Sensorineural hearing loss was observed in one case. In one patient a gusher effect occurred during surgery. The postoperative air-bone gap improved significantly compared to the preoperative gap (8 vs 29 dB HL, respectively), and the mean air-bone gap closure was 20 dB HL. In 78.7% of cases, the observed postoperative air-bone gap was less than 10 dB HL and in 14% it was between 11 dB HL and 20 dB HL. An ABG closure lower than 20 dB HL was achieved in a total of 92.7% of patients. CONCLUSIONS: Endoscopic stapes surgery is a safe procedure with a low risk of peri- or postoperative complications and is a possible alternative to the traditional microscopic surgical procedure in the treatment of otosclerosis.

Endoscopic Assisted Lateral Skull Base Surgery.

Pathology of the lateral skull base poses a unique challenge for the surgeon. An intimate knowledge of the anatomy and the various approaches used for accessing pathology of the lateral skull base is critical. Three novel, minimally invasive, transcanal approaches for the management of lateral skull base pathology are described herein along with their respective indications, advantages, and disadvantages.

Facial Nerve Neurophysiologic Assessment in Vestibular Schwannoma Removal with Transcanal Approach: A Pilot Clinical Study.

BACKGROUND: The transcanal transpromontorial approach has been introduced to remove vestibular schwannomas. As with other techniques, preservation of the facial nerve (FN) is challenging. This pilot study described FN outcomes of patients preoperatively and postoperatively assessed with electromyography (EMG) and blink reflex (BR). METHODS: Between September 2017 and December 2018, 10 patients (5 men; 5 women; mean age, 59.8 years; age range, 25-77 years) underwent removal of vestibular schwannoma via the transcanal transpromontorial approach. FN assessment using EMG/BR and clinical evaluation with the House-Brackmann (HB) grading scale was performed preoperatively and 2 months postoperatively. If facial impairment was present postoperatively, further analysis was performed 6 months after surgery. RESULTS: All 10 patients had normal FN function on preoperative EMG/BR. After 2 months, 4 patients had normal FN function on EMG/BR, 4 patients showed a slight delay of FN responses, 1 patient had moderate dysfunction, and 1 patient had consistent damage. After 6 months, among the 6 patients with a pathologic neurophysiologic study, consistent EMG/BR improvement was shown, with complete recovery in 3 cases. At the last follow-up, 8 patients had HB grade I, 1 patient had HB grade II, and 1 patient had HB grade III in 1, showing progression toward healing in 9 of 10 cases. CONCLUSIONS: The transcanal transpromontorial approach is an effective procedure for vestibular schwannoma removal. EMG/BR represents an objective evaluation method to verify FN recovery after surgery and confirms the low impact of this surgical procedure on the FN.

The Management of Tympanic Membrane Perforation With Endoscopic Type I Tympanoplasty.

OBJECTIVE: The objective of this study is to describe what we consider to be the state-of-the-art procedure for the treatment of tympanic membrane perforations, and to present the results attained in our institution. STUDY DESIGN: A retrospective cohort study, using data of Verona University Hospital, Italy. This medical record includes the data of 98 patients who underwent 100 transcanal endoscopic type I tympanoplasties from November 2014 to October 2017. SETTING: Tertiary referral center University Hospital of Verona, Italy. PATIENTS: Were enrolled 109 patients, that underwent endoscopic type I tympanoplasty in the period considered. Out of the selected patients, 11 (10.1%) were lost to long-term follow-up, and were therefore excluded from our study. Other exclusion criteria were surgical approaches that included other procedures. Patients whose follow-up was shorter than 6 months were excluded from this study. INTERVENTION: The technique is based on an endoscopic placement of underlay graft of temporal fascia or tragal cartilage. We consider the data of four surgeons from Verona University ENT department. MAIN OUTCOME MEASURE: In the study we considered the reduction of the Air Bone Gap as functional outcome and the integrity of the reconstruction as anatomical outcome of success. RESULTS: No major intraoperative complications were observed. The closure rate was 86%. The mean surgery time was 48.6 minutes. The air bone gap was improved within 20 DB HL in 89% of patient. Only 8% of patients needed revision surgery, and none needed a third surgical evaluation. CONCLUSION: Endoscopic ear surgery is by now a reality that has replaced in many cases exclusive microscopic ear surgery. Transcanal endoscopic type I tympanoplasty can be considered nowadays as an alternative technique for tympanic membrane perforations.

FrailSafe: An ICT Platform for Unobtrusive Sensing of Multi-Domain Frailty for Personalized Interventions.

The implications of frailty in older adults' health status and autonomy necessitates the understanding and effective management of this widespread condition as a priority for modern societies. Despite its importance, we still stand far from early detection, effective management and prevention of frailty. One of the most important reasons for this is the lack of sensitive instruments able to early identify frailty and pre-frailty conditions. The FrailSafe system provides a novel approach to this complex, medical, social and public health problem. It aspires to identify the most important components of frailty, construct cumulative metrics serving as biomarkers, and apply this knowledge and expertise for self-management and prevention. This paper presents a high-level overview of the FrailSafe system architecture providing details on the monitoring sensors and devices, the software front-ends for the interaction of the users with the system, as well as the back-end part including the data analysis and decision support modules. Data storage, remote processing and security issues are also discussed. The evaluation of the system by older individuals from 3 different countries highlighted the potential of frailty prediction strategies based on information and communication technology (ICT).

Endoscopic-Assisted Cochlear Implantation in Children with Malformed Ears.

OBJECTIVE: Complex middle and inner ear malformations are considered an important limitation for cochlear implant (CI) with traditional microscopic techniques. The aim of the present study is to describe the results of the endoscopic-assisted CI procedure in children with malformed ears. STUDY DESIGN: Case series with chart review of consecutive patients. SETTING: Two tertiary referral centers: University Hospital of Verona and University Hospital of Modena, Italy. SUBJECTS AND METHODS: In total, 25 children underwent endoscopic-assisted cochlear implantation between January 2013 and January 2018. The audiologic and neuroradiologic assessment showed profound hearing loss and malformation of the middle and inner ear in all children. A complete review of anatomic features, surgical results, and audiologic outcomes was performed. The surgical technique is described step-by-step, and the outcomes are detailed. RESULTS: All patients (mean age, 3.6 years; range, 2.8-9 years) underwent a transattical/endoscopic-assisted CI procedure. All children showed varying degrees of auditory benefit, as measured by routine audiometry, speech perception tests, and Categories of Auditory Performance scores (mean, 6). No immediate or late postoperative complications were noted. CONCLUSION: The endoscopic-assisted approach proved to be successful in cochlear implantation. The direct visualization and magnification allow (1) exploration of the tympanic cavity; (2) confirmation of all anatomic features, with strict control of the course of the facial nerve, round window area, and inner ear; and (3) performance of the cochleostomy with adequate insertion of the array.

Hearing Restoration During Vestibular Schwannoma Surgery With Transcanal Approach: Anatomical and Functional Preliminary Report.

OBJECTIVE: Hearing restoration has always been a dream in vestibular schwannoma (VS) surgery. The aim of this study is to describe an endoscopic assisted transcanal retrocochlear approach to the internal auditory canal (IAC) with total removal of the VS; simultaneously we assessed the anatomical and functional aspects of hearing restoration with cochlear implant (CI). STUDY DESIGN: A retrospective case series. SETTING: Tertiary referral center. PATIENTS: Six patients affected by VS involving the fundus of the IAC (Koos stage I-II) were included in this study. The patients already demonstrated symptoms of IAC involvement by the neuroma, with severe to profound hearing loss. INTERVENTIONS: Transcanal microscopic, endoscopic assisted, approach was chosen for total tumor removal. Preoperative and intraoperative electrophysiological monitoring was performed using electrically evoked auditory brainstem responses (EABR) to evaluate preservation of cochlear function. MAIN OUTCOME AND MEASURES: A retrospective evaluation of electrophysiological data collected during surgeries has been conducted; clinical outcomes, surgical complications, and postoperative radiological evaluations were also considered. RESULTS: Total tumor removal was achieved in all patients with no major complications. One patient showed temporary facial palsy (HB stage II). We were able to preserve cochlear function in five out of six patients. In those patients intraoperative monitoring with EABR was performed after tumor removal with good responses. CONCLUSIONS: Transcanal retrocochlear approach for VS removal allows preservation of cochlea and cochlear nerve function. This is the first step towards developing an effective surgical technique for VS removal and hearing rehabilitation with CI.

Expanded Transcanal Transpromontorial Approach: A Novel Surgical Technique for Cerebellopontine Angle Vestibular Schwannoma Removal.

Objective Vestibular schwannoma (VS) is a benign tumor of the lateral skull base. Different microscopic surgical techniques are described in literature: the retrosigmoid and translabyrinthine approaches are used to treat big tumors located in the cerebellopontine angle, and the middle cranial fossa approach is utilized for small tumors with good hearing preservation. The expanded transcanal transpromontorial (ExpTT) approach is a combined microscopic-endoscopic technique previously indicated for Koos stage I and II VS and now proposed for larger VS, up to 3 cm in diameter, with linear progression into the cerebellopontine angle and touching the brainstem. Study Design The study was a retrospective case series of patients who underwent ExpTT surgery for VS in our ear, nose, and throat department. Setting We reviewed the surgical videos and electrophysiologic data recorded during the surgical operations. Subjects and Methods From January 2015 to January 2017, 20 patients affected by Koos stage II and III VS underwent surgery in our department with the ExpTT approach. This novel technique is described step by step, with a focus on the surgical procedure and anatomic landmarks; outcomes are detailed in terms of early and late complications. The mean follow-up was 15 months. Results The ExpTT approach permitted, in all patients, gross total resection of the tumor without any complication and with preservation of facial nerve function. All patients had a good postoperative recovery. Conclusion The ExpTT technique is a new approach that combines the advantages of a microscopic technique with the ones offered by the endoscope in removal of VS.

Endoscopic approach for cochlear implantation in advanced otosclerosis: A case report.

HYPOTHESIS: Ossification of the cochlea was once considered to be a contraindication for cochlear implantation. Advances in cochlear implant technology and coding strategies have led to developments in different surgical procedures to manage cochlear ossification. The endoscopic technique allows a direct approach to the round window and the cochlea, especially in remodeled labyrinth, allowing a better vision of scala tympani. BACKGROUND: Tertiary referral ENT center. METHODS: Between January 2011 and February 2015 three patients with far advanced otosclerosis with partial obliteration of the cochlea were selected and underwent endoscopic-assisted cochlear implantation. RESULTS: In far advanced otosclerosis, endoscopy allowed a magnification of the anatomy of the round window, permitting the surrounding anatomical structures forming the anatomy of the niche to be identified, and avoiding a blind dissection. No postoperative complications were noted, in particular, no surgical site infection, no vertigo, and no facial nerve injuries. Implant activation was routinely performed 1 month after surgery. All monitoring till date has indicated that the external auditory ducts are well ventilated and there are no signs of extrusion. CONCLUSIONS: Ossification may occur as a consequence of the pathology of meningitis, chronic otitis media, severe otosclerosis, autoimmune inner ear diseases, temporal bone traumas, and other diseases. Advances in cochlear implant technology and coding strategies have led to developments in different surgical procedures to manage cochlear ossification. Supported by a number of years of experience in the field of otoendoscopic surgery, we propose a technique for cochlear implantation under unfavorable conditions using endoscopic-assisted surgery, especially in advanced otosclerosis. This technique permits us to extend the indication for cochlear implantation, and in our opinion will reduce the morbidity associated with this surgical procedure.

Traumatic Intraconal Foreign Body: Report of an Injury Corrected With Combined Surgical and Endoscopic Treatment.

BACKGROUND: Management of penetrating ocular splinter injuries is very controversial. Penetrating wounds of the orbit represent a complex therapeutic problem that requires a multidisciplinary approach. Endoscopic approaches to the orbit are currently performed through the lamina papyracea to access the medial part, or through large orbitotomies to access the lateral part. OBJECTIVE: To describe a novel combined approach to the lateral part of the orbit. METHODS: Clinical and surgical findings of intraorbital foreign body removal are presented. A minimal supraorbital osteotomy was performed, combined with endoscopic intraorbital dissection. RESULTS: The foreign body was removed, no postoperative complications were reported, and visual acuity increased from 2/10 preoperatively, to 8/10 one month after surgery. CONCLUSION: The present technique can be considered a safe and novel surgical approach to access the retrobulbar space and to treat the pathology of this anatomic region.
