RESUMO

OBJECTIVE: To describe clinical observations of patients with syndromic deafness. RESULTS: Deaf patients with CHARGE, Crouzon, and Wildervanck syndromes were monitored at the Russian Research Clinical Center for Audiology and Hearing Rehabilitation (Moscow) in different years. All of them were diagnosed having bilateral congenital deafness. After collecting anamnesis, evaluating the results of computed tomography of the temporal bones, and audiological examination, it was decided to conduct the cochlear implantation. CONCLUSION: The only method that allows patients with bilateral congenital deafness to gain hearing is the cochlear implantation. The malformations of the tympanic cavity structures, an abnormal course of the facial nerve canal lead to technical difficulties during the surgical stage of cochlear implantation. The navigation equipment, monitoring of the facial nerve makes it easier to find anatomical structures, as well as to avoid injuries.

RESUMO

Objective: To investigate the efficacy of CT-guided percutaneous mandibular angle radiofrequency thermocoagulation (RFT) of facial nerve through stylomastoid foramen for the treatment of hemifacial spasm. Methods: A total of 82 patients with primary facial spasm who underwent CT-guided RFT in the Department of Pain Medicine of Zhejiang Integrated Traditional Chinese and Western Medicine Hospital and Department of Pain Medicine of the First Hospital of Jiaxing from January 2019 to June 2021 were retrospectively analyzed, including 27 males and 55 females, aged 24-85 (59±11) years. All patients were divided into three groups according to the different puncture approaches: anterior mastoid approach group (Group A, n=35), posterior mastoid approach group (Group P, n=25) and mandibular angle approach group (Group M, n=22). The puncture time, the minimum stimulating current inducing the twitch of facial muscles on the affected side, the temperature at the end of RFT and the duration of RFT at this temperature, the total treatment time, as well as the degree of facial paralysis and complications 1 day after operation were compared among the three groups. Results: The puncture time of the Group A, Group P and Group M was (31.0±4.9) min, (31.9±6.5) min and (35.3±5.9) min, respectively, and the difference was statistically significant (P=0.020). The puncture time of the Group M was longer than that of the Group A and P (both P<0.05). The minimum stimulation current inducing the twitch of the affected facial muscle in the three groups was (0.5±0.2) mA, (0.4±0.1) mA and (0.3±0.1) mA, respectively, with a statistically significant difference (P=0.000). The minimum stimulation current in the Group M was less than that in the Group A and P (both P<0.05). The temperature at the end of RFT of the three groups was (78.6±8.1) ℃, (76.6±8.3) ℃ and (67.0±8.4) ℃, respectively, and the difference was statistically significant (P<0.001). The temperature of the Group M was lower than that of the Group A and P (both P<0.05). There were no significant differences among the three groups in the duration of RFT at the final temperature, the total treatment time, and the degree of facial paralysis 1 day after operation (all P>0.05). No hematoma, infection, hearing impairment and other complications occurred in all patients. Conclusion: CT-guided percutaneous RFT through stylomastoid foramen is efficacious in the treatment of hemifacial spasm, and the mandibular angle approach provides better performance.

RESUMO

<b>Introduction:</b> Patients often suffer from an elongated styloid process. This clinical entity is well known and is described as Eagle syndrome. The presence of this anatomical variation is not always associated with symptoms. However, there is a strong correlation between the elongated styloid process and Eagle syndrome </br></br> <b>Aim:</b> This study aims to calculate the incidence of elongated styloid processes in the Greek population, to analyze the morphometric characteristics of styloid processes, and to compare these among sexes. </br></br> <b>Material and methods:</b> This is a single-center retrospective study. All skulls were donated to the Department of Anatomy, the Ari-stotle University of Thessaloniki from January 2013 to May 2019 for research purposes. A styloid process longer than 30 mm was considered elongated. We used Welch's t-test for the statistical analysis of the data. </br></br> <b>Results:</b> The prevalence of elongated styloid processes was 35%. The average diameter was 3.32 mm and the average total length was 25.02 mm. There was no statistically significant difference between male and female skulls, though the female styloid processes were slightly longer and the male ones were slightly wider. Symmetry was recorded in 31% of skulls. Average axial angle was 650 but in 4% of cases it was less than 20<sup>0</sup>. </br></br> <b>Conclusions:</b> The elongated styloid process is not a rare entity. Eagle syndrome should always be considered in the differential diagnosis when patients report chronic sore throat. Our anatomical findings add a new dimension to the etiopathogenesis of Eagle syndrome.

RESUMO

INTRODUCTION: Internal auditory canal (IAC) diverticula, also known as IAC cavitary lesions or anterior cupping of the IAC, observed in otopathologic specimens and high-resolution computed tomography (CT) scans of the temporal bone are thought to be related to otosclerosis. Herein, we examined the usefulness of CT scans in identifying diverticula and determined whether IAC diverticula are associated with otosclerosis on otopathology. METHODS: One hundred five consecutive specimens were identified from the National Temporal Bone Hearing and Balance Pathology Resource Registry. Inclusion criteria included the availability of histologic slides and postmortem specimen CT scans. Exclusion criteria included cases with severe postmortem changes or lesions causing bony destruction of the IAC. RESULTS: Ninety-seven specimens met criteria for study. Of these, 42% of the specimens were from male patients, and the average age of death was 77 years (SD = 18 yr). IAC diverticula were found in 48 specimens, of which 46% were identified in the CT scans. The mean area of the IAC diverticula was 0.34 mm 2 . The sensitivity and specificity of detecting IAC diverticula based on CT were 77% and 63%, respectively. Overall, 27% of specimens had otosclerosis. Histologic IAC diverticula were more common in specimens with otosclerosis than those without (37.5% versus 16%; p = 0.019). Cases with otosclerosis had a greater mean histologic diverticula area compared with nonotosclerosis cases (0.69 mm 2 versus 0.14 mm 2 ; p = 0.001). CONCLUSION: IAC diverticula are commonly found in otopathologic specimens with varied etiologies, but larger diverticula are more likely to be associated with otosclerosis. The sensitivity and specificity of CT scans to detect IAC diverticula are limited.

RESUMO

The most common cause of lateral skull base fractures are still road traffic accidents, followed by falls. The radiologic classification into otic capsule-sparing or otic capsule-violating fractures correlates well with an increased risk of injury to the sensitive structures of the middle ear with otic capsule-violating fractures. In case of immediate onset complete facial nerve paralysis, decompression surgery is generally recommended if bony impingement can be demonstrated on high-resolution CT of the temporal bone. For many other facials nerve complications, recent publications have achieved good to excellent facial nerve recovery rates with watchful waiting under conservative treatment with prednisolone administration.

RESUMO

OBJECTIVE: This study aimed to describe the spatial distribution of osteocyte-depleted areas, so-called cellular voids, in the human otic capsule and compare it with that of otosclerosis. BACKGROUND: Systematic histological studies of the bony otic capsule have revealed an osteoprotegerin (OPG)-mediated inhibition of normal bone remodeling around the inner ear. The resulting accumulation of bony degeneration and dead osteocytes has been thoroughly documented, and the spatial distribution of dead osteocytes and matrix microcracks resembles that of the human ear disease otosclerosis. Clusters of dead osteocytes that may interfere with osteocyte connectivity and thereby the OPG signaling pathway have been described in human temporal bones. It is possible that these cellular voids create disruptions in the antiresorptive OPG signal that may give rise to local pathological remodeling. METHODS: Recently, a method of detecting cellular voids was developed. This study uses unbiased stereology to document the spatial distribution of cellular voids in bulk-stained undecalcified human temporal bone. RESULTS: Cellular voids accumulate around the inner ear and increase in number and size with age. Furthermore, cellular voids are more frequently found in the anterior and lateral regions of the otic capsule, which are known predilection sites of otosclerosis. CONCLUSION: This colocalization of cellular voids and otosclerosis suggests a causal relationship between focal degeneration and otosclerotic remodeling.

RESUMO

OBJECTIVE: IgG4-related disease (IgG4-RD) involving the temporal bone is an uncommon and underrecognized pathology often mistaken for malignancy. This systematic review is the first that aims to thoroughly analyze IgG4-RD of the temporal bone. DATABASES REVIEWED: Ovid MEDLINE, EMBASE, Cochrane Library, and Google Scholar. METHODS: We used the following search keywords: "lgG4-RD," "skull," "skull base," "cranial," "temporal bone," "inner ear." We additionally manually searched the bibliographies of relevant articles. The JBI Critical Appraisal Checklist for Case Reports and Case Series was used to assess the risk of bias; because of the scarcity of the reports, data were available through limited case series and reports; thus, data synthesis was not possible. RESULTS: We identified 17 studies with 22 cases with temporal bone involvement. The most common presenting symptoms were hearing loss, otalgia, and headache. The mastoid and petrous bone were the most affected anatomical areas. Both computed tomography and magnetic resonance imaging were used. Biopsies showed the characteristic lymphoplasmacytic infiltrate in all cases, with histopathology being the diagnostic modality that set the diagnosis. Most patients were treated with corticosteroids ± surgery or a combination of corticosteroids and immunosuppressants with 95.5% symptomatic response and disease control. CONCLUSION: IgG4-RD of the temporal bone radiologically manifests as space-occupying, lytic lesions; clinically, it presents with vague otological symptoms. Diagnosis involves a thorough workup, with histopathology being crucial in setting a definite diagnosis. IgG4-RD tends to respond well to systemic corticosteroids, whereas surgery is mostly required for diagnostic purposes.

RESUMO

BACKGROUND: The piezoelectric instrument (PEI) offers a novel technique for bone removal in ear surgery with a combination of micro-oscillation and cavitation. The aim of this review is to explore the advantages, disadvantages, and limitations of this instrument in comparison to the drill. MATERIALS AND METHODS: We conducted a search of PubMed/MEDLINE and Google Scholar in accordance with the PRISMA recommendations. The primary selection included all studies reporting on the use of PEI in ear surgery or its effect on the inner ear. Only studies with a control group were included in the secondary selection. RESULTS: The first search identified 49 studies between 2003 and 2022. These reported on a total of 1162 ear operations, during which PEI was used for various indications. Most data were based on uncontrolled retrospective studies or case reports (76%). Only one of the five controlled clinical studies was prospective and randomized. The advantages of PEI weighed against its limitations and disadvantages were critically analyzed in comparison to the drill. CONCLUSION: Piezoelectric surgery is an innovative and promising surgical technique in the temporal bone. PEI appears to enable safer and more precise bone removal in close proximity to soft tissue when compared to the drill. The slower bone removal and cost factors represent current limitations to its wider use in ear surgery.

RESUMO

ABSTRACT: The extraoral approach with the risk of facial nerve injury and the visible scar is commonly performed for an elongated styloid process, because intraoral styloidectomy is challenging for the deep and limited surgical field. The authors report minimally invasive intraoral styloidectomy using an endoscope with tissue retractor. A 57-year-old female was referred to our department with a left pharyngeal foreign body sensation and pharyngeal pain after head turning and neck compression. Clinical and radiological diagnosis was an elongated styloid process (Eagle syndrome). Because the styloid process could be palpated intraorally, the patient underwent endoscopically-assisted intraoral styloidectomy without tonsillectomy under general anesthesia as minimally invasive surgery. The styloid process was resected safely with a piezoelectric surgical device under endoscopic guidance. The postoperative course was uneventful without complications.

RESUMO

Background: The endolymphatic sac is an organ devoid of sensory receptors. It is connected with the endolymphatic compartment and contains endolymph. Endolymphatic sac tumor (ELST) is a rare neoplasm involving the middle and inner ear described in humans and dogs that does not show cellular characteristics of malignancy, but can be locally invasive and involve destruction of the temporal bone and adjacent structures. Case Description: An 8-month-old female cat was referred because of sudden onset of vestibular signs starting 3 days prior to referral. On clinical examination, the patient showed depression, right head tilt, left-sided facial paralysis, and horizontal nystagmus with fast phase to the left. The magnetic resonance images showed a voluminous extra-axial lesion, with irregular morphology and well-defined margins, with intracranial extension in the region of the pons, rostral medulla oblongata, cerebellar vermis, floccule, and left cerebellar hemisphere. Due to progressive clinical deterioration, the cat was euthanized 2 weeks later. A necropsy was then performed and histological samples were taken. The necropsy revealed the presence of a voluminous dark red irregular mass extending from the tympanic bulla to the posterior cranial fossa following the left glossopharyngeal nerve. The histopathological exam of the extra-axial lesion featured a nonencapsulated, moderately cellular, rather loose, proliferation of cuboidal to columnar epithelium breaching through chunks of an otherwise normal appearing dura mater and invading some cranial nerves. Sections of the cerebellum and brainstem revealed moderate, focal, impingement of the parenchyma with a very mild extension of the proliferating cells into the ventral left side of the medulla oblongata. Based on these histological characteristics, the lesion was defined as ELST, a rare neoplasm described in human beings and with two reports in dogs. Conclusion: To our knowledge, this is the first report describing an ELST in a cat.

RESUMO

OBJECTIVES: This study assessed the impact of the location of the chorda tympani nerve (CTN) origin on the round window (RW) accessibility during pediatric cochlear implantation (CI). We also tried to validate the radiologic method to measure the length between the origin of the CTN from the facial nerve to the stylomastoid foramen (CF-SM). STUDY DESIGN: It was a prospective observational case-series study. SETTINGS: The included CI surgeries were performed at tertiary referral institutions from November 2018 to August 2021. SUBJECTS: We included 146 pediatric patients who were candidates for CI. INTERVENTION: We measured the CF-SM length in the parasagittal cut of the preoperative high-resolution computed tomography. We also classified the intraoperative RW according to the accessibility through the ordinary posterior tympanotomy approach into accessible or inaccessible. MAIN OUTCOME MEASURE: We correlated the preoperative radiologic CF-SM length with the intraoperative RW accessibility. RESULTS: The radiologic CF-SM length ranged from 2.9 to 7.4 mm with a mean of 4.9 ± 1.03 mm. The RW was accessible in 107 patients and inaccessible in 39 patients. Spearman's correlation coefficient revealed a significant relationship between the location of CTN origin and the RW accessibility as the p value was less than 0.0001. CONCLUSIONS: We found a precise method to measure the CF-SM length in the parasagittal cut of the high-resolution computed tomography. We also found a significant impact of the location of the CTN origin on intraoperative RW accessibility. The radiologic CF-SM length of more than 5.4 mm had a powerful prediction capability of the RW inaccessibility.

RESUMO

BACKGROUND: Giant cell tumors (GCTs) and giant cell granulomas (GCGs) are giant cell-rich lesions that occur extremely rarely in the temporal bone and have similar clinical presentations. OBJECTIVES: We aimed to analyze the clinical features and introduce our staging system and surgical treatment. METHODS: Forty-six patients pathologically diagnosed with a giant cell lesion involving the temporal bone between October 2001 and October 2020 were reviewed retrospectively. The clinical characteristics, surgical approaches, and risk factors for recurrence were analyzed. RESULTS: GCTs and GCGs presented as masses centered on the temporomandibular joint with similar imaging features, including a thin, calcified shell and central scattered calcifications on a computed tomography scan. Differences were detected on magnetic resonance imaging in 29.6% (4/14) of GCG and 50% (16/32) of GCT cases; the remaining cases were not distinguishable. Based on our staging system and surgical strategy, 31.8% (7/22) of GCT and 10% (1/10) of GCG cases experienced recurrence, which compares to recurrence rates of 60% in GCT cases and 20% in GCG cases in previous studies. CONCLUSIONS: Specific clinical and preoperative imaging features help to make a diagnosis of temporal giant cell-rich lesions. Our staging system and surgical strategy could help surgeons tailor the surgical strategy.

RESUMO

BACKGROUND: An anomalous subarcuate loop (SL) of the anteroinferior cerebellar artery (AICA) is a rare anatomic variation, which increases the complexity and risk of vestibular schwannoma (VS) removal. However, preoperative diagnosis of this anomaly remains difficult. The aim of this study was to report three types of anomalous SLs encountered during VS removal and to describe the "Deep Subarcuate Fossa (SF)" sign and its significance in the diagnosis and treatment of an osseous-penetrating SL. METHODS: We prospectively observed 963 patients with newly/recently diagnosed VS who underwent surgical treatment performed by the senior author (P.Z.) from 2012 to 2021 and identified 16 patients with an anomalous SL. The SF was retrospectively measured on preoperative thin-slice temporal bone computed tomography in 963 patients. RESULTS: Three types of anomalous SLs were encountered during VS removal: the apex of the SL was embedded in the dorsal tumor capsule (type I, 1 case), the dura (type II, 8 cases), or the dura and bone (type III, 7 cases) surrounding the SF. The depth of the SF in 7 patients with a type III anomalous SL ranged from 2.3 to 7.0 mm (3.56 ± 1.56 mm), which was significantly larger than that in 845 patients without an osseous-penetrating SL (1.23 ± 0.43 mm) (p = 0.008). When the depth of the SF exceeded 2 mm, the sensitivity and precision of the diagnosis of a type III anomalous SL were 100% (7/7) and 31.8% (7/22), respectively. CONCLUSION: Three types of anomalous SLs may be encountered during VS removal, and AICA displacement is recommended before tumor removal. The "Deep SF" sign may indicate the existence of a type III anomalous SL and it can predict the depth of the AICA in the bone and guide the drilling of the bone around the vessel loop.

RESUMO

OBJECTIVE: This paper presents the inner ear modifications in Dar-es-Soltane II H5, an Aterian fossil possibly dated to 100 ka. MATERIAL: The remains consist of a large portion of the cranium including the face, the left frontal and temporal bones, part of the left parietal bone and greater wing of the sphenoid. METHODS: The bony labyrinth anatomy was investigated on existing micro-CT data acquired by the MPI-EVA. RESULTS: The observation of micro-CT sections revealed a partial filling of the semi-circular canals that raises question about its origin. A careful examination of the micro-CT sections shows that the elements present in the semicircular canals were denser than the sediments observed in other regions and cavities of the temporal bone. CONCLUSIONS: The current evidence suggests a pathological origin of this condition with partial ossification of the membranous labyrinth. The differential diagnosis indicates a case of labyrinthitis ossificans in its early stages. SIGNIFICANCE: This pathological condition can be responsible for permanent hearing loss and is associated with dizziness and vertigo. Along with the Singa skull, Dar-es-Soltane II H5 represents one of the oldest known cases of labyrinthitis ossificans. LIMITATIONS: The early stage of disease and the absence of the right temporal bone limit conclusions about the degree of disability of the individual and their dependence on the rest of the group. SUGGESTIONS FOR FURTHER RESEARCH: To carry out a paleopathological study of all the fossils from Dar-es-Soltane II.
