RESUMEN

Objective:Study on the value of quantitative measurement of key structures of inner ear by high resolution computer tomography(HRCT) in hearing evaluation of patients with congenital severe sensorineural hearing loss(SNHL). Methods:A total of 90 children with extremely severe SNHL diagnosed and treated in Beilun District People's Hospital from January 2018 to February 2021 were collected as the experimental group. In the same period, 90 children(180 ears) with normal inner ear structure and hearing were scanned because of head trauma and suspected temporal bone fracture. Logistic univariate and multivariate regression analysis were used to analyze the factors affecting the occurrence of extremely severe SNHL. Based on the results of multivariate analysis, a Nomogram prediction model was established. The model before and after internal correction was evaluated by the receiver working characteristic curve. Results:Inner ear malformation, SSCC bone island width, LSCC bone island width and cochlear height were independent risk factors for extremely severe SNHL. The results of Nomogram predictive model showed that cochlear height 34 points, LSCC bone island width 19 points, SSCC bone island width 22 points, inner ear malformation 37 points, the total score(112 points) corresponding to the incidence of extremely severe SNHL(0.3%). The actual C-index value of Nomogram prediction model is 0.858, the C-index of internal verification is 0.851, and the C-index of external verification is 0.847. The coincidence of the model is good. It is suggested that the model can effectively predict the risk factors of congenital extremely severe SNHL and has high prediction accuracy. Conclusion:The standardized measurement of SSCC bone island width, LSCC bone island width and cochlear height by HRCT is of great value in the diagnosis of microinner ear malformation in children with extremely severe SNHL.

RESUMEN

Objective:To identified the feasibility and normal range of cone beam computer tomography(CBCT) in the measurement of temporal bone. Methods:15 formalin fixed human cadaver head specimens were scanned by CBCT, high resolution CT, and Micro CT, respectively. Morphological parameter measurements of the middle and inner ear structures including ossicular chain, cochlea, semicircular canal and facial nerve were performed, and the results measured by the three scanning methods were compared. Results:None of the parameters measured by the three scanning methods were statistically significant except the thickness of stapes footplate(P<0.01) and the diameter of cochlear basal turn(P<0.01). CBCT was superior in detecting facial nerve bony canal dehiscence. Conclusion:CBCT has the advantages of short scanning time, low radiation dose and high resolution. It can accurately display the morphological characteristics of the temporal bone structures, and is a reliable evaluation method for otological surgery.

RESUMEN

Objective: To elucidate the clinical manifestations of temporal bone tympanic plate fracture and the correlation between treatment time after injury and its prognosis, and to discuss the importance of early treatment of tympanic fracture. Methods: Retrospective analysis was carried out on the clinical data of 15 patients(17 ears)with temporal bone tympanic plate fracture from March 2006 to July 2019. The course of disease was less than 1 month (initial stage) in 7 cases (7 ears), 1 month to 6 months (middle stage) in 2 cases (3 ears), and 6 months or more (late stage) in 6 cases (7 ears). The symptoms, signs, CT findings, pure tone audiometry results, surgical methods and clinical efficacy of each group were summarized. Results: Most patients with temporal bone tympanic plate fracture were referred to otology department by maxillofacial surgery. Fracture occured indirectly with the chin or zygomatic region as the direct stress point. Thirteen of the 15 patients had mental region wounds or scars, and 14 patients had external acoustic canal bleeding immediately after injury. In the initial-stage group, hearing was mostly unchanged, while in the middle and late-stage groups, hearing loss was mainly caused by conduction factors. In the initial stage group, 6 cases/7 cases were cured by external acoustic canal packing; External acoustic canal stenosis or atresia occurred in 2 cases in the middle-stage group and were cured by external acoustic canal plasty. All the 6 patients in the late-stage group had external acoustic canal stenosis or atresia, among whom 5 patients with external acoustic canal cholesteatoma were cured by external acoustic canal plasty, and the other one patient with middle ear cholesteatoma was cured by modified radical mastoidectomy and tympanoplasty after external acoustic canal plasty for three times. Conclusions: Temporal bone tympanic plate fracture is a special type of temporal bone fracture. In the early stage of temporal bone tympanic fracture, bleeding of the external acoustic canal is the main symptom, and hearing is normal mostly. Advanced conductive deafness may result from external acoustic canal stenosis and/or cholesteatoma formation later. Bleeding of the external acoustic canal and irregular bulge of the anterior wall of the external acoustic canal with mental region wound are important signs for early diagnosis of temporal bone fracture. Temporal bone tympanic fracture should be paid attention to, early detection and timely treatment can avoid external acoustic canal stenosis and atresia.

RESUMEN

INTRODUCTION: Eagle's syndrome is a poorly understood clinical entity that has variable presentations like recurrent throat pain or foreign body sensation, dysphagia, or facial pain. With a confirmed diagnosis, a surgical approach is considered appropriate for its treatment. This study aims to find out the prevalence of trans-oral extra tonsillar approach of styloidectomy among the operated cases of Department of Otolaryngology-Head and Neck Surgery at a tertiary care hospital. METHODS: A descriptive cross-sectional study was conducted among 1,475 who underwent surgery at the Department of Otolaryngology-Head and Neck Surgery in a tertiary care center of Nepal between July 2018 to September 2020 after receiving the ethical clearance from the Institutional Review Committee (Reference number: 0106201802). Convenience sampling was done and data was entered in Statistical Package for the Social Sciences version 20. Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. RESULTS: Among 1,475 patients enrolled in the study, 24 (1.62%) patients (95% Confidence Interval= 0.97-2.26) underwent trans-oral extra tonsillar approach of surgery for Eagle's syndrome during the study duration. CONCLUSIONS: The prevalence of styloidectomy among the operated cases of our study is low in comparison to other studies done in similar settings. Transoral extra tonsillar approach can be considered as a novel approach for surgical removal of the styloid process in Eagle's Syndrome.

RESUMEN

A very rare case of 46-yaer-old woman with chondromyxoid fibroma (CMF) of infralabyrinthine area of temporal bone was described in this article. The only manifestation of this disease was a severe temporary pain in the postauricular area with irradiation in the occipital bone and headache during the last 3 months. A detail description of the CT scan and MRI data was presented. Tumor removing was performed through the retrofacial approach with combination of the microscopic and endoscopic assistance technique, which allows to had a good visualization and controlling of tumor separation from the vital structures with hearing and facial nerve function preserve. Also, we presented a brief review of literature with differential diagnosis of the CMF of the temporal bone, which conducted to minimize the diagnosis mismatches in the otologic and head and neck practice and to optimize the treatment of patients with such tumor.

RESUMEN

Objective: Evaluation of the management and survival in patients treated for temporal bone squamous cell carcinoma (TBSCC) in a tertiary referral centre. Methods: Forty-nine patients underwent primary treatment for TBSCC. Thirty-six patients underwent a lateral temporal bone resection (LTBR) or subtotal temporal bone resection (STBR). Overall survival (OS) and disease-specific survival (DSS) analysis were assessed. Results: Five-year OS of the 49 patients was 39%. Five-year OS of the 36 patients who underwent LTBR or STBR was 46%. Tumour-free margins were achieved in all patients with T1 and T2 disease, in 59% patients with T3 tumours and 0% patients with T4 disease. Five-year DSS was 85% for all T1/T2 tumours, 53% for T3 tumours and 0% for T4 tumours. Clear resection margins was the only significant predictor of DSS in our cohort. Conclusions: The mainstay of treatment for TBSCC is temporal bone resection with tumour free resection margins, with or without adjuvant radiotherapy. Survival is negatively influenced by non-radical resection. T1 and T2 tumours can be managed safely with LTBR. More advanced disease requires a more extensive resection, with a higher likelihood of non-radical resections and decreased survival rates.

RESUMEN

BACKGROUND Eagle syndrome is a vascular compression syndrome that is caused by a very elongated styloid process and/or calcification of the stylohyoid ligament compressing the vascular or nerve structures of the neck, resulting in vascular congestion, thrombosis, or neurological symptoms (eg, dysphagia, neck pain, ear pain). Stylo-jugular venous compression syndrome is a subtype of Eagle syndrome and is caused by compression of the internal jugular vein. Treatment varies according to the symptoms and the severity of the compression, and it can be pharmacological or surgical, with vascular stenting and/or removal of the styloid process. We describe a rare case of left cerebral venous sinus thrombosis and ipsilateral internal jugular vein stenosis sustained by excessive length of the left styloid process. CASE REPORT A 36-year-old woman presented with recurrent episodes of drug-resistant headache and recent memory disturbances. She underwent cerebral and neck multidetector computed tomography-angiography and Doppler ultrasound of the epiaortic vessels that respectively revealed thrombosis of the left cerebral venous sinus and left internal jugular vein stenosis due to a very long styloid process. The patient was treated with anticoagulant drugs and experienced a gradual remission of symptoms. CONCLUSIONS Compression of the jugular vein by the styloid process is a rare entity, and it often goes undiagnosed when it is asymptomatic. Doppler ultrasound is a sensitive method for identifying jugular vein stenosis and can provide an estimated degree of stenosis, which is useful for treatment planning. Doppler ultrasound should be combined with multidetector computed tomography-angiography to rule out compression of other vascular structures and other causes of compression. Failure to treat these patients could have serious health consequences for them.

RESUMEN

BACKGROUND: It is extremely rare for primary non-Hodgkin's lymphomas to occur singly in the cranial vault. One case diagnosed as primary diffuse large B-cell lymphoma is reported, initially misdiagnosed as metastatic skull tumor, complicated with Trousseau syndrome. CASE DESCRIPTION: The patient was a 60-year-old Japanese woman with no particular previous medical history. In a head computed tomography examination for vertigo, bone destructive skull tumor covering the right frontal, parietal, and temporal bones was incidentally discovered. As positron emission tomography indicated an abnormal accumulation in the large intestine and multiple cerebral infarctions suspicious of Trousseau syndrome were observed on magnetic resonance images, a metastatic skull tumor due to colorectal cancer was first considered. However, various tumor markers were negative, and colonoscopic biopsy indicated no colorectal abnormality. After pathological examination of the resected tumor, it was diagnosed as diffuse large B-cell lymphoma. The tumor affected muscles and skin but did not develop in the brain or the dura mater. As further general examination revealed no other abnormalities, we considered that it was primary diffuse large B-cell lymphoma in the cranial vault associated with Trousseau syndrome. Treatment with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and high-dose methotrexate reduced the residual lesion; coagulation abnormalities, which are frequently associated with Trousseau syndrome, also improved. CONCLUSIONS: Skull tumors can result from a variety of malignancies, and their diagnosis may be complicated with Trousseau syndrome. However, even in cases of a single lesion in the cranial vault without invasion of the central nervous system, diffuse large B-cell lymphoma should be considered as a differential diagnosis.

RESUMEN

Eagle's syndrome was first described by Watt Eagle in 1937, as a syndrome of vague orofacial and cervical pain. He reported two variants, classic styloid and stylocarotid artery syndrome. Eagle's syndrome is a non-perceived and underdiagnosed clinical condition of the head and neck. This anomalous entity presents with neck pain, globus sensation, difficulty in turning the head, dysphagia, odynophagia and various other symptoms occurring as a result of irritation to the nearby structures. The surgical management of Eagle's syndrome consists of two major approaches: the transoral and the transcervical approaches. We report a case of classic bilateral elongated styloid process syndrome, treated with transcervical styloidectomy for painful left elongated styloid process. This gave permanent relief to the patient. The transcervical surgical approach for resection of elongated styloid process in patients with Eagle's syndrome appears to be safe and effective, although the risk for transient marginal mandibular nerve weakness is notable.

RESUMEN

A 52-year-old man with glottic-supraglottic tumour underwent open partial horizontal laryngectomy (OPHL) IIb. On the 12th day postoperative, laryngoscopy showed necrotic tissue at the level of pexy and an increased distance between tongue base and neoglottis; the neck CT showed cricoid arch rupture and rupture of the pexy. By re-examining the preoperative CT images, the ossification of stylohyoid ligament (Eagle syndrome) was detected and supposed as the possible cause of cricoid rupture due to its traction on the hyoid bone and therefore on the pexy. The stylohyoid ligaments were cut at their insertion on the hyoid bone and a tracheohyoidopexy was performed. Two months after surgery, the patient had only some swallowing impairments. This case represents a complication in OPHL II never reported in literature caused by an undiagnosed Eagle syndrome in preoperative, pointing out the importance to search for any anatomical anomaly that could jeopardise the success of the surgery.

RESUMEN

OBJECTIVE: The present study aimed to explore the relationship between the arcuate eminence (AE) and superior semicircular canal (SSC) using the constructive interference steady-state (CISS) sequence. PATIENTS AND METHODS: After conventional magnetic resonance imaging, a total of 71 patients underwent the CISS sequence in thin-sliced coronal sections. RESULTS: In all patients, the SSC was delineated on both sides. In contrast, the AE was identified only in 29 of 71 patients (40.8%) on both sides, varying in shape and relative location to the SSC in the mediolateral dimension. The shortest distance between the highest point of the SSC and middle fossa floor was 1.3 ± 1.1 mm on the right side and 1.3 ± 0.9 mm on the left with considerable variability. A dehiscent SSC with a distance less than 0.2 mm was found in 11.3% of 142 sides. On 22 sides (15.5%), the site on the middle fossa floor, reaching the SSC with the shortest distance (reference point) corresponded to the apex of the AE, equally on the right and left. On 36 sides (25.4%), the distance between the reference point and the apex of the AE was measured as 3.0 ± 1.1 mm on the 18 right sides and 3.7 ± 1.6 mm on the 18 left sides. CONCLUSIONS: The relationship between AE and SSC is highly variable. Arcuate eminence was not a reliable landmark of the SSC. High-resolution CISS sequence is useful for exploring these structures.

RESUMEN

Cochlear implant, as the most successful artificial auditory implant, brings tens of thousands of patients with severe or profound sensorineural hearing loss back to the world of sound every year. With the expansion of surgical indications, a large number of difficult cases bring new challenges for cochlear implantation. As a new technology, cone beam CT has the double advantages of high spatial resolution and low radiation. It is considered as the second revolution of CT technology, which shows unique value in the application of cochlear implantation. This article reviews the basic principles of cone beam CT and its application and research progress in cochlear implantation.

RESUMEN

HYPOTHESIS: In temporal bones with otitis media, fibrin and neutrophil extracellular traps (NETs) form a fibrous network with bacteria, which is involved in growth of bacterial clusters/biofilms and chronicity of disease. BACKGROUND: NETs and fibrin are important in host defense against pathogens; however, their role in otitis media is not well understood. METHODS: Eight human temporal bones with serous otitis media, 30 with serous-purulent otitis media, 7 with mucoid otitis media, 23 with mucoid-purulent otitis media (OM), 30 with purulent OM, and 30 with chronic otitis media were selected based on histopathologic findings. Fibrous material with bacteria was detected with hematoxylin-eosin, Gram-Weigert, and propidium iodide stains; and its composition was analyzed with immunohistochemistry. RESULTS: Extensive formations of fibrous material with bacteria were observed in 30% of temporal bones with serous-purulent otitis media, 29% with mucoid otitis media, 50% with mucoid-purulent OM, 57% with purulent OM, and 67% of temporal bones with histological evidence of chronic otitis media. Some of these formations showed large bacterial clusters or biofilms. Immunohistochemical analysis showed that fibrous structures were composed of fibrin or NETs. CONCLUSIONS: Formations of fibrous material with bacteria were detected in human temporal bones with different types of otitis media. Inflammatory cells were observed mostly in areas with low presence of fibrous structures. The network of fibrous material seems to prevent clearance of bacteria by phagocytic cells and thus influences growth of bacterial clusters or biofilms. Fibrin and NETs may be important for the recurrences and chronicity of disease, and contribute to clogging of tympanostomy tubes in children.

RESUMEN

BACKGROUND: Although many studies have suggested that air cells may play an important role in sigmoid sinus diverticulum and/or dehiscence (SSDD)-induced pulsatile tinnitus (PT), the exact effects remain unclear. This study aims to quantitatively investigate the effect of different degrees of pneumatization of temporal bone on sound transmission from the sigmoid sinus to the tympanic cavity. METHODS: In the clinical study, 25 patients were enrolled to measure the sound intensity and frequency of SSDD-induced PT. In the experimental study, sound inputs at different frequencies at the dehiscent sigmoid plate were measured and compared among realistic object models of different degrees of pneumatization, when sound intensity in the tympanic cavity was fixed as the level of the PT sound intensity sensed by patients. RESULTS: The sound intensity sensed by PT patients was 34.0 ± 13.0 dB SPL, which represented the sound intensity in the tympanic cavity transmitted from the dehiscent sigmoid plate. In the experimental study, when sound received in the tympanic cavity was fixed at 34 dB SPL, the mean inputs of sound intensity at the dehiscent sigmoid plate were 46.9, 46.2, 45.2, 47.1, 57, 57.4, and 74.1 dB SPL in a hypo-pneumatized model; 42.6, 43, 41.5, 43.2, 47.3, 58.2, and 78.8 dB SPL in a moderately pneumatized model; 52.6, 52.8, 48.1, 61, 64.2, 82.4, and >87.3 dB SPL in a well-pneumatized model; and 47.2, 46.2, 45.4, 49.4, 54.9, 66.6, and 77.7 dB SPL in hyper-pneumatized model, with increased sound frequencies (125-8000 Hz). The mean sound transmission distances were 41.7 mm, 45.2 mm, 47.6 mm, and 48.4 mm in successively better pneumatized models. CONCLUSION: Sound reduces while passing through air cells and attenuation is lowest in the moderately pneumatized temporal bone, followed by the hypo- and hyper-pneumatized temporal bones, and the highest in the well-pneumatized temporal bone. Lower-frequency sound attenuation (≤1000 Hz) is less than that of higher-frequency sound (>1000 Hz).

RESUMEN

INTRODUCTION: Orofacial and cervical pain are a frequent reason for neurology consultations and may be due to multiple pathological processes. These include Eagle syndrome (ES), a very rare entity whose origin is attributed to calcification of the stylohyoid ligament or elongation of the temporal styloid process. We present a series of five patients diagnosed with ES. METHODS: We describe the demographic and clinical characteristics and response to treatment of 5 patients who attended the headache units of 2 tertiary hospitals for symptoms compatible with Eagle syndrome. RESULTS: The patients were 3 men and 2 women aged between 24 and 51, presenting dull, intense pain, predominantly in the inner ear and the ipsilateral tonsillar fossa. All patients had chronic, continuous pain in the temporal region, with exacerbations triggered by swallowing. Four patients had previously consulted several specialists at otorhinolaryngology departments; one had been prescribed antibiotics for suspected Eustachian tube inflammation. In all cases, the palpation of the tonsillar fossa was painful. Computed tomography scans revealed an elongation of the styloid process and/or calcification of the stylohyoid ligament in 3 patients. Four patients improved with neuromodulatory therapy (duloxetine, gabapentin, pregabalin) and only one required surgical excision of the styloid process. CONCLUSIONS: Eagle syndrome is a rare and possibly underdiagnosed cause of craniofacial pain. We present 5 new cases that exemplify both the symptoms and the potential treatments of this entity.

RESUMEN

HYPOTHESIS/BACKGROUND: We hypothesize that following head trauma there is a difference in temporal bone (TB) pathology in cases with and without skull fracture. Although conductive, sensorineural, mixed hearing loss, and TB pathology following head trauma have been reported, to our knowledge, there are no studies that have compared the pathology of the TB in cases with and without skull fracture. METHODS: We analyzed 34 TBs from donors who had a history of head trauma (20 with skull fracture and 14 without fracture), and 25 age-matched controls without clinical or histological evidence of otologic disorders. We documented the presence and location of TB fracture, ossicular injury, and cochlear hemorrhage and evaluated the loss of spiral ganglion cells and sensory hair cells, damage to the stria vascularis, and the presence of endolymphatic hydrops. RESULTS: We found a significant loss of outer hair cells in the upper basal, lower, and upper middle turns of the cochlea (p = 0.009, =0.019, =0.040, respectively), a significant loss of spiral ganglion cells (p = 0.023), and cochlear hemorrhage predominantly in the basal turns secondary to head trauma. Interestingly, these findings were significantly observed in TBs from donors with a history of head trauma without skull fracture. CONCLUSION: The greatest damage was to the cochlear basal turn. Our findings suggest that head trauma may result in tonotopic high frequency sensorineural hearing loss. TBs from donors with skull fracture have less pathologic changes than those without.

RESUMEN

OBJECTIVES: The purpose of the study is to evaluate the audiological, radiological, and examination findings of patients who have been treated for hearing loss (HL) due to head trauma and evaluated in terms of causality to reveal current data, and to highlight the steps to be taken. METHODS: We retrospectively reviewed the reports of cases that had applied for disability with HL due to head injury and had been evaluated by the Forensic Medicine Institute between January 01, 2009 and January 01, 2019. RESULTS: Of the total cases of head trauma, 52.42% were not vehicle-related, and cases were observed to be concentrated in the age range of 19-40 (55.92%; n = 283). Although otorrhagia/otorrhea was the most common finding in all types of trauma, TM perforation was the most common finding in blast-type injuries. While the rate of newly developed unilateral HL was 84.2%, 72.7% of the patients had sensorineural hearing loss (SNHL) . Temporal bone fractures were detected in 59.3% of the cases, and 60.2% of them were of the longitudinal type. Facial paralysis (FP) was detected in 28.6% of the cases, and there was no statistically significant difference between the groups in terms of HL compared to those without FP. Other nerve palsy was detected in 4.9% of the cases, and N. Abducens paralysis was the most common. CONCLUSION: Accompanying intracranial nerve injury, temporal fracture, and intracranial pathologies are considerably high in patients who develop HL following head trauma. The first examination requires a multidisciplinary approach to guide future disability applications.
