RESUMEN

Objective: To explore the imaging evaluation of cerebrospinal fluid (CSF) otorrhea associated with inner ear malformation (IEM) in children. Methods: The clinical data of 28 children with CSF otorrhea associated with IEM confirmed by surgical exploration in Beijing Children's Hospital, from Nov, 2016 to Jan, 2021, were analyzed retrospectively,including 16 boys and 12 girls, aged from 8-month to 15-year and 8-month old, with a median age of 4-year old. The shapes of stapes were observed during the exploration surgery, and the imaging features of temporal bone high resolution CT(HRCT) and inner ear MRI pre- and post-operation were analyzed. Results: In 28 children with CSF otorrhea, 89.3%(25/28) had stapes footplates defect during exploration. Preoperative CT showed indirect signs such as IEM, tympanic membrane bulging, soft tissue in the tympanum and mastoid cavity. IEM included four kinds: incomplete partition type I (IP-Ⅰ), common cavity (CC), incomplete partition type Ⅱ (IP-Ⅱ), and cochlear aplasia (CA); 100%(28/28) presented with vestibule dilation; 85.7%(24/28) with a defect in the lamina cribrosa of the internal auditory canal. The direct diagnostic sign of CSF otorrrhea could be seen in 73.9%(17/23) pre-operative MRI: two T2-weighted hyperintense signals between vestibule and middle ear cavity were connected by slightly lower or mixed intense T2-weighted signals, and obvious in the coronal-plane; 100%(23/23) hyperintense T2-weighted signals in the tympanum connected with those in the Eustachian tube.In post-operative CT, the soft tissues in the tympanum and mastoid cavity decreased or disappeared as early as one week. In post-operative MRI, the hyperintense T2-weighted signals of tympanum and mastoid decreased or disappeared in 3 days to 1 month,soft tissues tamponade with moderate intense T2-weighted signal were seen in the vestibule in 1-4 months. Conclusions: IP-Ⅰ, CC, IP-Ⅱ and CA with dilated vestibule can lead to CSF otorrhea. Combined with special medical history, T2-weighted signal of inner ear MRI can provide diagnostic basie for most children with IEM and CSF otorrhea.HRCT and MRI of inner ear can also be used to evaluate the effect of surgery.

RESUMEN

BACKGROUND: Patulous Eustachian tube (pET) is a rare dysfunction of the Eustachian tube described in humans. It is characterized by failure of the ET to close, resulting in unrestricted passage of air, sound and material between the nasopharynx and the middle ear. OBJECTIVE: To report a case of pET associated with otitis in a dog. ANIMAL: A 6-year old-female spayed Dachshund dog. METHODS AND MATERIALS: Otoscopic examination, cytological evaluation, culture and susceptibility, computerized tomography (CT), video-otoscopic flushing and surgery. RESULTS: Left ear otoscopic examination revealed erythema, purulent frothy discharge, ceruminous gland hyperplasia, stenosis and a partial tear of the tympanum. Cytological evaluation from the left external canal showed neutrophils, macrophages, rods and cocci. Aerobic culture showed predominantly multidrug-resistant Pseudomonas aeruginosa. The CT findings of the left ear included chronic changes in the external canal, marked lysis of the tympanic bulla and marked dilation of the ET. During video-otoscope flushing, saline drained through the mouth. Bilateral incomplete hypoplasia of the soft palate was noted. Total ear canal ablation and bulla osteotomy with ET dissection were curative. Histopathological findings were compatible with chronic otitis externa (OE) and media. CONCLUSION AND CLINICAL IMPORTANCE: To the best of the authors' knowledge, this is the first case of pET described in animals. The ET dysfunction and palatine defect were likely the cause of the otitis in this dog. Clinicians should investigate pET in animals with signs of OE characterized by frothy liquid and food fragments in the ear canal in addition to sneezing after drinking water.

RESUMEN

The Prolactin Inducible Protein (PIP) is a 15 kDa protein secreted by normal apocrine glands, including salivary, lacrimal and sweat glands. PIP levels are normally low in the mammary glands of healthy individuals, but high levels have been observed in pathological conditions of the breast such as benign breast cystic disease and breast cancer. While the function of PIP is not well elucidated, accumulating evidence strongly point to a role in both innate and adaptive immunity. Using PIP deficient mice (Pip-/- mice) our laboratory demonstrated that loss of PIP function led to impaired T helper type 1 response and cell mediated immunity. In the present study we provide additional supporting evidence showing abnormal lymphocytic distribution in primary and secondary lymphoid organs of Pip-/- mice. Significant morphological changes in the Eustachian tube, an immune-protected site where PIP is normally found, were also associated with the absence of PIP. Collectively, these results further support an immuno-regulatory role for PIP and have implications for a spectrum of immune-related illnesses including otitis media and hearing loss as well as breast cancer.

RESUMEN

BACKGROUND: Paper patching, a method that places cigarette paper over the most mobile quadrants of the tympanic membrane, is one of the treatment options for patulous eustachian tube (PET). AIMS/OBJECTIVES: The objective of this study was to compare the outcomes of two different treatment strategies for PET. MATERIAL AND METHODS: Twenty-three patients underwent paper patching of the tympanic membrane and 16 patients were treated with nasal saline irrigation with or without ipratropium bromide nasal spray. Medical records were reviewed for resolution of PET symptoms as categorical variables (complete remission, partial remission, or no improvement) with a minimum follow-up of 3 months. RESULTS: Immediately after undergoing paper patching, 20 of the 23 patients (87.0%) reported complete remission (CR). The percentage of CR after paper patching was 82.6% at 1 month and 65.2% at 3 months. A greater percentage of patients reported CR of aural symptoms in the paper patching group than in the nasal irrigation group at both 1 and 3 months after treatment (p < .05). CONCLUSIONS AND SIGNIFICANCE: Repetitive paper patching resolves aural discomfort in most PET patients for at least 3 months and can be considered as a first-line treatment option for PET in the outpatient setting.

RESUMEN

INTRODUCTION: Patients with Turner syndrome (TS) have craniofacial malformations, such as Eustachian tube hypoplasia and dysfunction and velar dysfunction, which foster acute otitis media. The aim of this study was to inventory pediatric otologic disorders in patients with TS at their first ENT consultation in our center. PATIENTS AND METHODS: We reviewed the ENT consultation data of pediatric TS patients followed in our center between 2005 and 2015: otoscopy, hearing threshold, and history of acute otitis media or ENT surgery. Data were compared according to karyotype: X monosomy (45,X), mosaic (45,X/46,XX), isochromosome (46,Xi [Xq]), X ring chromosome X (XrX), with Y material, and "other". RESULTS: Ninety patients, with mean age 11.9years (±4.8years) at first ENT consultation, were included: 29% showed tympanic abnormality on otoscopy, 21% had hearing loss, 24% had history of recurrent acute otitis media; 18% had undergone adenoidectomy, 24% T-tube insertion, and 5.6% tympanoplasty. No particular karyotype was associated with higher risk of hearing loss or acute otitis media. CONCLUSION: Patients with TS showed high prevalence of pediatric otologic disorders; they therefore require close and prolonged ENT follow-up.

RESUMEN

OBJECTIVE: To assess the acoustic transmission characteristics of the Eustachian tube (ET) in living subjects in verified patent and closed ET states to facilitate the detection and quantification of ET function using acoustic measures such as sonotubometry. PATIENTS: The two subjects in this study had no history of ear disease nor previous ear surgery and were capable of volitionally opening and closing their ET. INTERVENTIONS: Tympanometry and otologic examinations were used to confirm ET patent and closed states by observing tympanic membrane movement with respiration and by acoustic immitance measurements during forced respiration. A series of 500-ms long chirps containing frequencies from 100 Hz to 10 kHz were introduced into the nasal cavity during both ET states and recorded by microphones in both the contralateral naris and external auditory canal. MAIN OUTCOME MEASURES: Acoustic energy transmission through the ET across the 0.1 to 10 kHz frequency range in the closed state versus the patent state. RESULTS: An increase in acoustic energy transmission occurs across the frequencies of 1 to 4 kHz between the closed and patent ET states, particularly in frequencies below 2.5 kHz. CONCLUSIONS: Results support sonotubometry as a potential diagnostic tool for ET dysfunction. Acoustic differences between the ET states manifest as a general increase in transmitted signal amplitude. Characterizing the acoustic properties in the verified patent and closed ET states allows investigators to more reliably interpret sonotubometric tests of ET function.

RESUMEN

Objetivo Caracterizar o sistema auditivo periférico de indivíduos com síndrome de Down, por meio da audiometria convencional e de altas frequências. Métodos Estudo do tipo transversal e observacional. Participaram 15 indivíduos com síndrome de Down, de ambos os gêneros, entre 7 e 15 anos de idade. Foram realizados os seguintes procedimentos: Meatoscopia, Timpanometria com pesquisa do reflexo acústico ipsilateral e contralateral, Audiometria Tonal, Audiometria Vocal e Audiometria de Altas Frequências. Resultados Houve predomínio de perda auditiva condutiva de grau leve, em uma ou ambas as orelhas. As médias dos limiares auditivos para a audiometria convencional ficaram abaixo de 20 dBNA e, para a audiometria de altas frequências, ficaram entre 20 e 40 dBNA. O coeficiente de correlação de Pearson revelou correlação moderada positiva, entre os limiares de 9 a 14 kHz e a idade. Conclusão De forma geral, não foram observadas diferenças significativas, quando comparadas as orelhas direita e esquerda de indivíduos com síndrome de Down, na audiometria tonal, imitanciometria e logoaudiometria. A maioria das crianças apresentou alteração de orelha média e perda auditiva condutiva. A audiometria de altas frequências sugere o início de prejuízo da função coclear, que pode estar associado às otites médias frequentes e/ou à degeneração coclear precoce. .


Purpose This study sought to characterize the peripheral auditory system of individuals with Down syndrome (DS) using conventional and high-frequency audiometry. Methods We performed a cross-sectional and observational study. Fifteen individuals with DS, who were of both genders and between 7 and 15 years of age, participated in this study. The following procedures were performed: otoscopy, tympanometry with ipsilateral and contralateral acoustic reflex, pure-tone audiometry, vocal audiometry and high-frequency audiometry. Results There was a predominance of mild conductive hearing loss in one or both ears. The mean hearing thresholds for conventional audiometry were below 20 dB HL and between 20 and 40 dB HL for high-frequency audiometry. The Pearson correlation coefficient indicated a moderate positive correlation between the 9-14 kHz thresholds and age. Conclusion Overall, no significant differences were observed when comparing the right and left ears of individuals with DS, in regards to pure-tone audiometry, immittance testing and speech audiometry. Most children showed middle ear abnormalities and conductive hearing loss. Moreover, high-frequency audiometry suggested the onset of impaired cochlear function, which may be associated with frequent otitis media episodes and/or early cochlear degeneration. .

RESUMEN

BACKGROUND: Patulous eustachian tube (pET) can result in transmission of sound from the pharynx to the middle ear (ME) via an abnormally patent ET. The objective of this study was to evaluate the technical feasibility of a reversible transnasal procedure for pET using an occluded silastic catheter to close the ET. METHODS: Ten sides were evaluated in five cadaver heads. Size 14, 16, and 18G catheters were occluded with bone wax to create a semirigid solid tube. They were placed transnasally, under endoscopic guidance through the ET orifice to span the entire ET length. Proper placement in the ME was confirmed by tympanotomy. Each attempt was graded on a four-point scale based on ease of placement: 3+, 2+, 1+, and 0. RESULTS: The 16G was the easiest to place with the best fit and was confirmed in the ME in eight cases. The 14G catheter was next easiest to place and was observed in the ME in seven cases. It generally had an extremely tight fit and propensity to impart mucosal trauma. The 18G was the most difficult to place and was observed in the ME in six cases. The catheter was noted to displace easily because of a loose fit. Tympanic membrane or ossicular injury was not noted in any trial. CONCLUSION: These cadaveric data suggest that a semirigid catheter provides the technical capability to reversibly occlude the ET via the transnasal endoscopic route. Further confirmation is necessary in human studies to determine its effectiveness for management of pET.

RESUMEN

A Tessier no. 7 cleft is a lateral facial cleft which originates from the oral cavity and extends towards the tragus, involving both soft-tissue and skeletal components. A male patient presenting with both maxillary jaw duplication and bilateral Tessier no. 7 clefts, which has been reported only twice in the literature, is described. Bilateral facial clefts, macrostomia and chondro-cutaneous remnants were noted, which were repaired and resected. With further growth, facial asymmetry and asymmetric facial nerve dysfunction became apparent. Radiographic examination showed an accessory maxillary jaw and a flattened and hypoplastic right coronoid process. A maxillary alveolar cleft was also present between the left second bicuspid and the second permanent molar. This case may represent an under-recognized phenotype with an unusual combination of maxillary jaw duplication, macrostomia, Tessier no. 7 clefts, and chondro-cutaneous remnants. A long-term follow-up of these patients is recommended as they often develop craniofacial deformities later in life.

RESUMEN

OBJECTIVES/HYPOTHESIS: Patulous eustachian tube remains a challenging management problem in otolaryngology. The autophony experienced by this patient population can be severe, and as yet no reliable surgical method exists to reduce or eliminate this annoying symptom. Our objective was to develop a novel endoscopic technique to assist these patients. STUDY DESIGN: Longitudinal case series. METHODS: A prospective longitudinal study was conducted of a series of consecutive patients undergoing surgery for patulous eustachian tube. Under transnasal endoscopic guidance, using a combination of fat plugging, endoluminal cauterization, and suture ligation, 14 ears underwent surgical treatment during a 4-year period. The main outcome measure assessed was the level of autophony present after surgery as compared to baseline. Audiometric outcomes, surgical time, and complications were also recorded. RESULTS: There was sustained satisfactory subjective improvement in the autophony in 12 of the 14 ears (85.7%) at primary surgery, with nine of these 12 ears (75%) demonstrating full autophony cessation. Wilcoxon signed rank test showed a significant improvement in autophony in the study population compared to baseline (z = 3.16, P < .001). The mean operating length of time per ear over the full duration of our series was approximately 45 minutes. Postoperative audiometry showed that surgery had no impact on hearing. CONCLUSIONS: Multilayer endoscopic ligation of the patulous eustachian tube resulted in a high autophony improvement rate. The procedure is technically straightforward, and results were sustained at 6-month follow-up.

RESUMEN

Genetic predisposition is recognized as an important pathogenetic factor in otitis media (OM) and associated diseases. Mutant Lmna mice heterozygous for the disheveled hair and ears allele (Lmna(Dhe/+)) exhibit early-onset, profound hearing deficits and other pathological features mimicking human laminopathy associated with the LMNA mutation. We assessed the effects of the Lmna(Dhe/+) mutation on development of OM and pathological abnormalities characteristic of laminopathy. Malformation and abnormal positioning of the eustachian tube, accompanied by OM, were observed in all of the Lmna(Dhe/+) mice (100% penetrance) as early as postnatal day P12. Scanning electronic microscopy revealed ultrastructural damage to the cilia in middle ears that exhibited OM. Hearing assessment revealed significant hearing loss, paralleling that in human OM. Expression of NF-κB, TNF-α, and TGF-ß, which correlated with inflammation and/or bony development, was up-regulated in the ears or in the peritoneal macrophages of Lmna(Dhe/+) mice. Rugous, disintegrative, and enlarged nuclear morphology of peritoneal macrophages and hyperphosphatemia were found in Lmna(Dhe/+) mutant mice. Taken together, these features resemble the pathology of human laminopathies, possibly revealing some profound pathology, beyond OM, associated with the mutation. The Lmna(Dhe/+) mutant mouse provides a novel model of human OM and laminopathy.

RESUMEN

OBJECTIVES: Evaluation of the effect of conservative and surgical treatment in patients with patulous Eustachian tube (PET) associated with habitual sniffing. STUDY DESIGN: Retrospective case review. SETTING: University hospital otolaryngology department. PATIENTS: Ninety-seven (23.4%) of 414 PET patients were found to have habitual sniffing to alleviate uncomfortable aural symptoms. Of these, 38 PET patients with sniffing habit were selected. INTERVENTIONS: Conservative intervention included instructions to stop sniffing and nasal instillation of saline. Surgical interventions used ventilation tube (VT) insertion to the eardrum and/or transmyringeal insertion of the PET plug (PEP). MAIN OUTCOME MEASURES: Relief of uncomfortable symptoms and stopping sniffing. RESULTS: In 52 (53.6%) of the 97 sniff-positive cases, retraction-type eardrum abnormalities or operated ear due to cholesteatoma were identified, whereas normal bilateral eardrums were observed in 34 (87.2%) of 39 sniff (-) cases. Abnormal findings in the eardrum were significantly more common in the sniff-positive group than in the sniff-negative group (p < 0.0001). Twenty-three patients (65.7%) stopped sniffing with conservative treatment. VT insertion was performed in 8 ears. Subsequent PEP was necessary in 2 of the 8 ears because of PET symptoms. PEP was successful in the other 11 ears, including one ear which needed additional VT insertion because of middle ear effusion. CONCLUSION: The management of habitual sniffing is difficult, but blocking the Eustachian tube by nasal instillation of saline and/or PEP could help PET patients to stop sniffing.

RESUMEN

La trompa patulosa es aquella trompa de Eustaquio que permanece permanentemente abierta y se asocia a ciertas condiciones como baja de peso y embarazo, entre otras, que tienen como denominador común la pérdida de tejido en la porción cartilaginosa de la tuba auditiva (trompa de Eustaquio). Tiene manifestaciones clínicas diversas, siendo la autofonía la principal de ellas. El diagnóstico se basa en la historia clínica, examen físico y un alto grado de sospecha por parte del examinador. Para esto, es indispensable el examen clínico mediante otoscopía e idealmente endoscopía nasal, eventualmente se requiere de otras técnicas, cuya utilidad está aún en investigación. Desde su reconocimiento como entidad clínica se han intentado diversos tratamientos médico-quirúrgicos, con resultados también diversos. Por este motivo, se requiere una evaluación de cada paciente en particular para definir su manejo específico. Esperamos con este artículo, presentar una revisión actualizada de la literatura acerca de una patología de importancia creciente, con énfasis en las alternativas de tratamiento que han demostrado mayor efectividad.


A patulous auditory tube is a condition in which the Eustachian tube remains constantly open, and it is associated to certain conditions such as weight loss and pregnancy, among others, which have in common tissue loss in the cartilaginous portion of the Eustachian tube. Its clinical manifestations are varied, the main one being autophony Diagnosis is based on clinical history and physical examination. For the health professional to suspect the condition, an otoscopy and ideally a nasal endoscopy are necessary. Eventually, other diagnosing techniques may be required, but their usefulness is still under discussion. Since its acceptance as a clinical entity, several surgical and medical treatments have been tried, with varied results. For this reason, each patient should be individually evaluated in order to decide a specific management. We present an updated literature review of a pathology of increasing importance, emphasizing the treatment alternatives that have demonstrated to be more effective.

RESUMEN

This report presents a 55-year-old woman who underwent 2 Teflon injections in 1971 for a patulous eustachian tube. The patient returned in 2006 with a bloody left otorrhea. A positron-emission tomography-CT scan demonstrated a 2-cm hypermetabolic parapharyngeal mass, initially interpreted as a skull base tumor. Repeat neck CT confirmed a 2-cm hyperattenuated left parapharyngeal granulomatous mass. This is the first reported case of a Teflon granuloma presenting as a false-positive parapharyngeal mass.

RESUMEN

OBJECTIVE: The patulous eustachian tube (ET) seems to be caused by a longitudinal concave defect in the mucosal valve at the superior aspect of its anterolateral wall and causes troublesome autophony of one's own voice and breathing sounds. Patulous ET reconstruction was evaluated to analyze whether submucosal graft implantation to fill in the concavity within the patulous tubal valve may produce lasting relief of symptoms. STUDY DESIGN: Prospective trial. SETTING: Tertiary referral center, ambulatory surgery. PATIENTS: Fourteen ETs in 11 adults with 1 or more years of confirmed continuous patulous ET symptoms refractory to medical care. INTERVENTION: Endoluminal patulous ET reconstruction was performed in 14 separate cases using a combined endoscopic transnasal and transoral approach under general anesthesia. A submucosal flap was raised along the anterolateral wall of the tubal lumen up to the valve and mobilized superiorly off of the basisphenoid. The pocket was filled with autologous cartilage graft or Alloderm implant, restoring the normal convexity and competence to the mucosal lumen valve. MAIN OUTCOME MEASURE: Autophony symptoms were scored as 1) complete relief; 2) significant improvement, satisfied; 3)significant improvement, dissatisfied; 4) unchanged; or 5)worse. RESULTS: All 14 cases reported immediate complete relief of autophony. Results with an average follow-up of 15.8 months are as follows: 1 (7%) case had complete relief; 5 (36%) had significant improvement, satisfied; 7 (50%) had significant improvement, dissatisfied; and 1 (7%) was unchanged. There were no complications. Correlation between patulous ET and other conditions was strongest with previous tubal dysfunction. Autophony of voice, but not breathing sounds, was also found to be experienced by 17 (94%) of 18 patients with superior semicircular canal dehiscence syndrome and could be easily mistaken for patulous ET autophony. CONCLUSION: Patulous ET seems to be caused by a concave defect in the tubal valve's anterolateral wall. Submucosal graft implantation to restore the normal convexity to the valve wall seems to provide lasting relief of symptoms. Long-term study is needed. It is important to differentiate between the autophony of semicircular canal dehiscence syndrome and patulous ET.

RESUMEN

First branchial cleft is the only branchial structure that persists as the external ear canal, while all other clefts are resorbed. Incomplete obliteration and the degree of closure cause the varied types of first branchial cleft anomalies. They were classified based on the anatomical and histological features. We present an unusual type of first branchial cleft anomaly involving the external auditory canal, the middle ear and the nasopharynx through the eustachian tube.

RESUMEN

Otite média secretora (OMS) unilateral em adultos é uma doença pouco comum e que deve ser rigorosamente investigada devido à possível associação com afecções benignas e malignas da nasofaringe.
