BACKGROUND: The endoscopic modified Lothrop procedure (EMLP) has become a frequently utilized procedure in rhinologic surgery. One of the most serious complications of the procedure is cerebrospinal fluid leak, which may occur due to lack of recognition of the anterior skull base in the region of the first olfactory filum (FOF), or direct injury to the FOF itself. OBJECTIVES: To evaluate the position of the head of the middle turbinate (MT) relative to the FOF, which is an important landmark in the EMLP...

Robotic-assisted surgery has gained popularity for otolaryngology procedures. It provides high-definition images and surgical precision to perform diverse procedures. It is an alternative to the operating microscope, endoscope, or exoscope when reaching hidden anatomical structures in the ear. In this proof-of-concept study, we aim to demonstrate the possibility of using a robotic-assisted device to perform ear surgery in conjunction with the microscope or the endoscope. In total, there were 9 ear and lateral skull base procedures performed with the use of robotic-assisted surgery...

During the last decades, neuro-otological surgery has progressively reduced functional morbidity, including facial nerve damage. However, the occurrence of this sequela may significantly impact on patients' quality of life. The aim of this narrative review is to provide an update on the patho-physiological and clinical issues related to facial nerve damage in oto-neurological and skull base surgery, in the light of a comprehensive therapeutic and rehabilitative approach to iatrogenic disfunctions. The narrative review is based on a search in the PubMed, Scopus, and Web of Science databases...

OBJECTIVES: We describe 10 new cases of otogenic (n = 8) and nonotogenic (n = 2) skull base osteomyelitis (SBO) in previously healthy children and review the literature on SBO in the pediatric population. METHODS: We retrospectively analyzed the medical records of 10 children (age range 0.9-12.8 years) discharged with a diagnosis of SBO between 2015 and 2020 in 2 children's hospitals in central Israel. RESULTS: Five patients presented with fever and 5 with otological signs and symptoms...

BACKGROUND: This study aimed to discuss 3 cases of congenital cholesteatoma located posterior to the sigmoid sinus, with no/minimal involvement of mastoid, and compare them with cases presented in the literature to better define this rare entity. METHODS: Retrospective chart analysis of 3 congenital cholesteatomas located posterior to the sigmoid sinus treated surgically in 2 skull-base centers and literature review. Though congenital cholesteatoma can arise outside the middle ear, only a few cases presenting in the retrosigmoid occipital bone have been described earlier...

OBJECTIVE: The timing for resuming continuous positive airway pressure (CPAP) postoperatively after skull base surgery remains controversial because of the risk of pneumocephalus. We determined the safety of immediate CPAP use after middle cranial fossa (MCF) spontaneous cerebrospinal fluid (sCSF) leak repair with bone cement. STUDY DESIGN: Prospective cohort study. SETTING: Tertiary academic medical center. PATIENTS: Thirteen consecutive patients with CPAP-treated obstructive sleep apnea and temporal bone sCSF leaks who underwent skull base repair with hydroxyapatite bone cement between July 2021 and October 2022...

PURPOSE: Middle and inner ear procedures target hearing loss, infections, and tumors of the temporal bone and lateral skull base. Despite the advances in surgical techniques, these procedures remain challenging due to limited haptic and visual feedback. Augmented reality (AR) may improve operative safety by allowing the 3D visualization of anatomical structures from preoperative computed tomography (CT) scans on real intraoperative microscope video feed. The purpose of this work was to develop a real-time CT-augmented stereo microscope system using camera calibration and electromagnetic (EM) tracking...

BACKGROUND: With a rising incidence of cerebrospinal fluid (CSF) leaks, endoscopic endonasal CSF leak repair is increasingly performed. Current approaches utilize a variety of materials including free mucosal grafts and vascularized flaps, but post-op leaks continue to be reported. Steroid-eluting bioabsorbable stents (SES) are used during functional endoscopic sinus surgery for chronic rhinosinusitis to reduce inflammation and scarring while maintaining patency of sinus ostia. OBJECTIVE: The aim of this study is to assess the feasibility of SES as a graft/flap bolster for endoscopic endonasal CSF leak repair...

Endolymphatic sac tumors (ELST) are low-grade papillary adenocarcinoma originating from the endolymphatic sac. Usually slow-growing, with local aggressiveness and a low risk of distant metastases, ELST can be sporadic but also frequently associated with von Hippel Lindau disease. The current treatment of ELST is primarily surgical resection. A 55-year-old woman accessed our otologic tertiary level referral center for a sudden worsening of hearing loss in her left ear and vertigo. A magnetic resonance (MRI) and computer tomography scan study subsequently showed a mass in the petrous bone; hence, the presence of an ELST was hypothesized...

PURPOSE: Robotic assistance in otologic surgery can reduce the task load of operating surgeons during the removal of bone around the critical structures in the lateral skull base. However, safe deployment into the anatomical passageways necessitates the development of advanced sensing capabilities to actively limit the interaction forces between the surgical tools and critical anatomy. METHODS: We introduce a surgical drill equipped with a force sensor that is capable of measuring accurate tool-tissue interaction forces to enable force control and feedback to surgeons...

OBJECTIVE: The "presigmoid corridor" covers a spectrum of approaches using the petrous temporal bone either as a target in treating intracanalicular lesions or as a route to access the internal auditory canal (IAC), jugular foramen, or brainstem. Complex presigmoid approaches have been continuously developed and refined over the years, leading to great heterogeneity in their definitions and descriptions. Owing to the common use of the presigmoid corridor in lateral skull base surgery, a simple anatomy-based and self-explanatory classification is needed to delineate the operative perspective of the different variants of the presigmoid route...

BACKGROUND: Exoscope has been used in otoneurologic surgery in several reports. However, most ear surgeries are performed using either microscope or endoscopy today. The purpose of this study is to present our subjective and objective experience of using this instrument in our institution. METHODS: 16 ears with different severity and condition in 15 consecutive patients were enrolled. A questionnaire with 12 questions was sent to different participants, including surgeons, residents, medical students, and scrub nurses in the operation room...

OBJECTIVE: Skull base osteomyelitis may rarely present in the sphenoid bone or clivus without an otologic source. This is referred to as central skull base osteomyelitis (CSBO). Knowledge regarding CSBO is limited to case reports and small case series. Here we present a case series to further describe typical patient characteristics, clinical presentation, and clinical course associated with this rare infection. METHODS: All patients treated at a single academic tertiary care institution for CSBO from 2016 through 2020 were identified...

OBJECTIVE: To assess the early outcomes of two types of proton therapy: passive scattering proton therapy (PSPT) and pencil beam proton therapy (PBPT). METHODS: The consecutive patients who had surgery in our facility were retrospectively reviewed. RESULTS: Thirty-two patients were identified (PBPT 22 patients [69%]). The mean (±standard deviation [SD]) tumor size was 3.8±1.8 cm, and the most common location was the upper clivus (41%)...
