Thermal Analysis of an Ultrasonic Aspirator Micro Claw Tool Compared With Standard High-Speed Drilling During Internal Auditory Canal Opening in a Cadaveric Model.

Background: The ultrasonic aspirator micro claw tool (UAmCT) can be used to remove the bone of the internal auditory canal (IAC) during vestibular schwannoma resection via the retrosigmoid approach (RSA) without the risk of a spinning drill shaft. However, the thermal profile of the UAmCT during IAC removal has not been reported.

Objective: To compare the thermal profile of the UAmCT during access of the IAC to that of a conventional high-speed drill (HSD) and to present an illustrative case of this application.

Otolaryngologic manifestations of Mpox: the Atlanta outbreak.

Background: In 2022, Mpox (MPX) has become clinically relevant as otolaryngologists are evaluating this exotic disease process due to its many otolaryngologic manifestations.

Aims/objective: To characterize our cohort of otolaryngology-relevant MPX confirmed cases.

Materials And Methods: A descriptive case series was performed retrospective review.

Contralateral Transmaxillary Approach to Petrous Apex Granuloma with Lateral Maxillotomy: 2-Dimensional Operative Video.

The endoscopic endonasal approach (EEA) has proven to be a valuable tool to access the petrous apex (PA). Although lesions located medial to the PA can be easily accessed through an EEA with minimal risk to the internal carotid artery (ICA), more laterally seated lesions represent a surgical challenge. The contralateral transmaxillary approach is an effective extension of the normal EEA to the PA, allowing a more lateral trajectory and thereby reducing the risks connected to paraclival ICA manipulation.

Exoscope-Assisted Middle Cranial Fossa Approach for Repair of Tegmental Defects: A Cadaveric and Clinical Study.

Background: Recent studies highlighted how exoscopes may be employed to approach the lateral skull base. The use of exoscope-assisted procedures to repair middle cranial fossa (MCF) defects has not been fully explored. The surgical microscope in the same circumstances has been associated with relevant limitations, such as its physical obstruction, among others.

Retrosigmoid Vestibular Neurectomy for Meniere Disease: A Technical Note.

Background: Meniere disease (MD) is an idiopathic peripheral pathology involving the acoustic apparatus. One of the most critical challenges in managing MD is intractable vertigo. In this context, retrosigmoid vestibular neurectomy has been described as a safe and effective technique to manage this symptom when it is resistant to first- and second-line treatments.

Objective: To compare rates of cochlear implant referral and cochlear implantation across different races and to compare audiometric profiles of these patients.

Study Design: Retrospective study.

Setting: Academic tertiary care institution.

Spontaneous Skull Base Cerebrospinal Fluid Leaks and Their Relationship to Idiopathic Intracranial Hypertension.

Background: The association between spontaneous skull base cerebrospinal fluid (CSF) leaks and idiopathic intracranial hypertension (IIH) has been suggested, but its significance remains unclear.

Objective: To estimate the prevalence of IIH in spontaneous skull base CSF leak patients.

Methods: Systematic collection of demographics, neuro-ophthalmic and magnetic resonance imaging evaluation of spontaneous skull base CSF leak patients seen pre- and post-leak repair in one neuro-ophthalmology service.

The Prevalence of Superior Semicircular Canal Dehiscence in Patients With Mastoid Encephalocele or Cerebrospinal Fluid Otorrhea.

Objective: To evaluate the association between mastoid encephalocele or cerebrospinal fluid (CSF) otorrhea and concurrent superior semicircular canal dehiscence (SSCD).

Study Design: Retrospective case-control study with chart and imaging review.

Setting: University-affiliated tertiary referral center.

Landmarks for the preservation of the middle temporal artery during mastoid surgery: Cadaveric dissection study.

Importance: The middle temporal artery flap is a vascularized periosteal flap that is highly useful for otologic reconstruction including the middle cranial fossa, mastoidectomy defect, and external auditory canal. The course of the artery is close to the external auditory canal and is easily injured during preliminary exposure and elevation of flaps.

Objectives: To describe the course of the middle temporal artery in relation to the external auditory canal and the superficial temporal artery in order to enhance preservation and use in otologic reconstruction.

Review of a single surgeon's stapedotomy cases performed with a nickel titanium prosthesis over a 14-year period.

Conclusion: Stapes surgery with a nickel titanium prosthesis is a safe and well-tolerated procedure that leads to a significant improvement in hearing outcomes.

Objective: To identify the efficacy and safety of stapedotomy procedures performed with a nickel titanium prosthesis for patients with otosclerosis.

Methods: A review of 431 unique stapedotomies performed over 14 years by a single surgeon at an academic tertiary care center yielded 312 cases with nickel titanium prosthesis that met inclusion criteria of otosclerosis diagnosis, initial surgery in operative ear, and presence of pre-operative and post-operative audiograms.

Diagnostic Challenges in a Case of IgG4-RD Affecting the Temporal Bone.

Introduction: Immunoglobulin G4-related disease (IgG4-RD) is a recently described fibroinflammatory condition with a characteristic histology. While IgG4-RD can affect a great variety of anatomical sites, it has been seldom described in the temporal bone.

Methods: Herein, a case IgG4-RD occurring in the temporal bone of a 35-year-old woman is reported.

Spontaneous defects between the mastoid and posterior cranial fossa.

Conclusions Spontaneous defects between the mastoid and the posterior cranial fossa are exceedingly rare. Patients with these lesions may have a lower BMI compared to those with middle cranial fossa encephaloceles, but are otherwise demographically similar. This study recommends repair via a transtemporal approach to allow for examination of the entire posterior face of the temporal bone.

Cerebrospinal fluid leaks following septoplasty.

We conducted a retrospective review to identify the characteristics of cerebrospinal fluid (CSF) leak in patients who had undergone septoplasty and in selected patients who had experienced a spontaneous CSF leak. CSF leak is a known but infrequently reported complication of septoplasty; to the best of our knowledge, only 4 cases have been previously published in the literature. A review of our institution's database revealed 3 cases of postseptoplasty CSF leak.

Slide tracheoplasty applied to acquired subglottic and upper tracheal stenosis: an experimental study in a canine model.

Objective: To assess the applicability and complications of slide tracheoplasty in the management of subglottic and upper tracheal stenosis in experimental animals.

Design: Subglottic stenosis was induced in 10 dogs by cauterizing the subglottic area and the upper 3 to 4 cm of the trachea. After 21 days, the severity of stenosis ranged from 30% to 60%.

Sigmoid sinus diverticulum: a new surgical approach to the correction of pulsatile tinnitus.

Objective: Tinnitus represents a bothersome symptom not infrequently encountered in an otology practice. Tinnitus can be the harbinger of identifiable middle or inner ear abnormality; but more frequently, tinnitus stands alone as a subjective symptom with no easy treatment. When a patient complains of tinnitus that is pulsatile in nature, a thorough workup is indicated to rule out vascular abnormality.
