Objective: To analyze the clinical characteristics of pediatric external auditory canalkeratosis obturans(KO). Method: Retrospective analyze the clinical data of twenty-three patients were diagnosed with external auditory canal cholesteatoma(EACC). Their chief complaint, the course of the disease, clinical characteristics,CT manifestations,surgical procedure and prognosis were retrospectively analyzed. The clinical characteristics between EACC and KO were compared.Result: Twenty cases(22 ears) were eventually diagnosed as KO. Among them, 2 cases were bilaterally involved. In the remaining unilateral cases, right ear was involved in 11 cases and left ear in 7 cases. All patients complained otalgia(100%). Purulent otorrhea was found in 17 ears(77.3%), and hearing loss withpurulent otorrhea in 3 ears(13.6%). Otoscopic examination found 17 ear with granulation(77.3%).CT scan found deformation of the osseous ear canal and displacement of the tympanic membrane because of compression in 18 ears(81.8%), and the bony canal was absorpt because of pression in 7 cases(38.9%).All patients underwent otoendoscopic operation,and tympanic membrane perforation was found in 4 cases.Postoperative pathologic examination results were keratin epithelial. Conclusion: EACC is easily confused with KO. KO should be considered in the following circumstances: patient who complained of ear pain, ear granulation with purulent discharge, or circinate deformation of the osseous ear canal and displacement of the tympanic membrane in CT scan.

Objective: To summarize the clinical characteristics and clinical treatment of congenital cholesteatoma (CC) of the middle ear in children, provide early diagnosis methods and explore standardized diagnosis and treatment plan.Method:A retrospective chart review of 94 patients with a diagnosis of middle ear cholesteatoma, in Beijing Children's Hospital, between 2009 and 2015 was carried on. 14 patients with CC were identified using the criteria proposed by Levenson, and were divided into two groups according to the course of disease. The course of disease in group A was less than 3 months, and group B was more than 3 months. The main complains, diagnostic methods and Potsic's stage of temporal bone CT findings were recorded.Result:①The age of 14 cases of congenital cholesteatoma of the middle ear ranged from 3.33 to 10.17 years, with the median age of 7.20 years. ②Hearing loss (13/14, 92.86%) was the most common complain. Finding methods included hearing screening and CT scan (11/14, 78.57%), tympanotomy (2/14, 14.28%) and otoscopic examination (1/14, 7.14%). ③There were 6 people in group A and 8 in group B. According to Potsic's grading standard, the difference between the two groups was statistically significant (P=0.043). ④The preoperative Air-Bone conduction threshold Gap (ABG) in A and B two groups were (38.10±7.43) dB and (42.09±9.96) dB, respectively, and there was no significant difference in analysis (P=0.427). ⑤The difference between pre-ABG and post-ABG ［(36.26±5.56）dB and （21.70±3.80）dB, P=0.004］ was significant. Canal wall up mastoidectomy was the preferred procedure and 11/14 (78.57%) patients had this surgery done.Conclusion: The shorter the course of disease, the lower the stage of cholesteatoma of the middle ear indicates the importance of early detection. But congenital cholesteatoma is more occult, and even within 3 months, cholesteatoma can cause severe damage to the hearing and middle ear structure. Early screening programs can recommend hearing screening and CT scan to facilitate early intervention.
- FDG-PET/CT for diagnosis and follow-up of necrotizing (malignant) external otitis. [Journal Article]
- LLaryngoscope 2018 Dec 14
- CONCLUSIONS: 18F-FDG-PET/CT is a reliable imaging modality for diagnosis, disease localization, and decision making regarding treatment cessation. 18F-FDG-PET/CT should be considered as the imaging modality of choice for initial diagnosis and follow-up in NEO patients. Larger, controlled studies are warranted.

- LLaryngoscope 2018 Dec 11
- CONCLUSIONS: Angiosarcoma of the temporal bone can arise in the setting of chronic otitis media. In this case, postmortem temporal bone sections demonstrated viable cancer despite chemoradiation. Inflammatory infiltrates crossing from the middle ear/mastoid into the labyrinth and central nervous system illustrate pathways for the development of otogenic meningitis.

Surfer’s ear, or exostoses of the external auditory canal, is a slowly progressive disease from benign bone growth as a result of chronic cold water exposure. It is a condition most commonly associated with surfing but seen in anyone repeatedly exposed to cold water such as swimmers, divers, kayakers, and participants of other maritime activities. Usually asymptomatic, external auditory exostoses (EAE) can cause symptoms such as hearing loss, repeated infections, otorrhea, ear fullness, and cerumen impaction. Treatment usually involves medical management but may include surgery if symptoms become severe.

- CONCLUSIONS: The contradictory reaction of VOR in MD patients may result from the high specificity but low sensitivity of CP in the horizontal vHIT. EH volume in the vestibule affects the caloric response but does not affect the vHIT response.

Disorders of the inner-ear balance organs can be grouped by their manner of presentation into acute, episodic, or chronic vestibular syndromes. A sudden unilateral vestibular injury produces severe vertigo, nausea, and imbalance lasting days, known as the acute vestibular syndrome (AVS). A bedside head impulse and oculomotor examination helps separate vestibular neuritis, the more common and innocuous cause of AVS, from stroke. Benign positional vertigo, a common cause of episodic positional vertigo, occurs when otoconia overlying the otolith membrane falls into the semicircular canals, producing brief spells of spinning vertigo triggered by head movement. Benign positional vertigo is diagnosed by a positional test, which triggers paroxysmal positional nystagmus in the plane of the affected semicircular canal. Episodic spontaneous vertigo caused by vestibular migraine and Ménière's disease can sometimes prove hard to separate. Typically, Ménière's disease is associated with spinning vertigo lasting hours, aural fullness, tinnitus, and fluctuating hearing loss while VM can produce spinning, rocking, or tilting sensations and light-headedness lasting minutes to days, sometimes but not always associated with migraine headaches or photophobia. Injury to both vestibular end-organs results in ataxia and oscillopsia rather than vertigo. Head impulse testing, dynamic visual acuity, and matted Romberg tests are abnormal while conventional neurologic assessments are normal. A defect in the bony roof overlying the superior semicircular canal produces vertigo and oscillopsia provoked by loud sound and pressure (when coughing or sneezing). Three-dimensional temporal bone computed tomography scan and vestibular evoked myogenic potential testing help confirm the diagnosis of superior canal dehiscence. Collectively, these clinical syndromes account for a large proportion of dizzy and unbalanced patients.

- Prevalence of Arnold nerve reflex in subjects with and without chronic cough: Relevance to Cough Hypersensitivity Syndrome. [Journal Article]
- PPPulm Pharmacol Ther 2018 Nov 13
- CONCLUSIONS: The greater than 11-fold prevalence of the Arnold nerve reflex in adults with chronic cough compared with healthy volunteers and adults with respiratory disease but without chronic cough, supports the concept of the Cough Hypersensitivity Syndrome (CHS), in which vagal hypersensitivity is proposed to underlie chronic refractory cough. The absence of increased prevalence among children with chronic cough suggests that CHS is an acquired condition, perhaps triggered by viral respiratory infection or other environmental factor.
