- Diagnostic Accuracy of Ocular Vestibular Evoked Myogenic Potentials for Superior Canal Dehiscence Syndrome in a Large Cohort of Dizzy Patients. [Journal Article]
- EHEar Hear 2018 Jun 07
- CONCLUSIONS: oVEMP was able to identify all subjects affected by SCDS, according to our diagnostic criteria, in a large cohort of unselected dizzy patients. The AC oVEMP amplitude parameter showed optimal sensitivity and high specificity for SCDS and may represent an ideal screening test for SCDS among dizzy patients. This is noteworthy when considering that not all SCDS patients express the clinical key features of vestibular hypersensitivity to sound or pressure change, even though most complain of dizziness.
- External auditory canal cholesteatoma and benign necrotising otitis externa: clinical study of 95 cases in the Capital Region of Denmark. [Journal Article]
- JLJ Laryngol Otol 2018 Jun 11; :1-5
- CONCLUSIONS: It is suggested that external auditory canal cholesteatoma and benign necrotising otitis externa are in fact the same disease, and therefore the diagnosis of external auditory canal cholesteatoma should be changed to benign necrotising otitis externa. Microangiopathy has a leading role in the aetiology. Surgery should be conducted in most cases.

Ticks are obligate parasites on animals and sometimes humans. They usually suck the blood of the hosts and can carry various infectious diseases as a vector. Otoacariasis is the presence of ticks and mites within the ear canal and relatively common in domestic and wild animals. However, tick infestations of human ear canals are rarely reported in the scientific literature and hardly occur in developed countries. Herein, we report a rare case of otoaracariasis involving Haemaphysalis longicornis . A 9-year-old girl living in a suburb presented with otalgia of left ear for 1 day. Otoscopic examination revealed a huge insect occluding the tympanic membrane. Tick removal and washing of external auditory canal was done successfully. The causative tick was identified as the H. longicornis. To our knowledge, this is the first reported case of human otoacariasis by a H. longicornis in Korea.

Ceruminous adenoma is an extremely rare condition that arises in the external auditory canal. The right ear canal in a 32-year-old man was obstructed by a ceruminous adenoma mimicking otitis externa and its symptoms. The lesion was resected under microscopic view using a transcanal approach. There were no tumor-related symptoms postoperatively and he has been disease free for 1 year after surgery.
- Retrobulbar steatitis and meningitis/empyema secondary to right otitis media, right otitis interna and an inflammatory polyp in a cat. [Journal Article]

The purpose was to describe a case of retrobulbar steatitis and meningitis in a cat caused by otitis media, otitis interna and an inflammatory polyp in the middle ear. Investigations included ophthalmic and neurological examinations, haematology and biochemistry, magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) analysis and aerobic, anaerobic bacterial and fungal culture of material from the middle ear. A 6-year-old female neutered domestic-short-haired cat presented with right-sided exophthalmos and resistance to retropulsion. Anisocoria, reduced corneal sensation and oculocephalic movements and low Schirmer tear test (STT1) were found. An MRI revealed the right external ear canal and tympanic bulla to be fluid filled with presence of a thickened contrast-enhancing mucosa. Contrast enhancement extended into the calvarium, as marked thickening and contrast enhancement of the pachymeninges, and further rostrally through the right orbital fissure into the orbit. The retrobulbar tissues were swollen, resulting in mild exophthalmos. Enrichment culture of material from the middle ear revealed Klebsiella pneumonia susceptible to marbofloxacin. The cat underwent a total ear canal ablation with removal of the cartilaginous cuff at the external auditory meatus and local debridement and curettage. A polypoid structure was removed from the middle ear. No bulla osteotomy was performed. Horner's syndrome was present immediately following surgery. The cat received a course of systemic dexamethasone (1mg/cat SID/3 weeks) tapered off and marbofloxacin (2mg/kg SID/2 weeks). Follow up at 120 days showed no recurrence of the symptoms. The Horner's syndrome and low STT1 had resolved and returned to normal values respectively. This case highlights the importance of MRI in the investigation of retrobulbar diseases. MRI is a useful tool for the evaluation of the extent of the lesion and the appearance of adjacent structures in which additional potentially life-threatening abnormalities, such as meningitis, can be seen.
- High-Frequency Horizontal Semicircular Canal Function in Certain Menière's Disease. [Journal Article]
- EHEar Hear 2018 May 14
- CONCLUSIONS: Pathological low vHIT gain values are rarely observed in patients with certain Menière's disease, while refixation saccades occur very frequently. In the majority of patients, saccades occur bilaterally. In Menière's disease, in contrast to vestibular neuritis, there is no compensatory decrease of saccade latency over time.
- Functional and Anatomical Outcome of Inside Out Technique For Cholesteatoma Surgery. [Journal Article]
- AJAm J Otolaryngol 2018 Jul - Aug; 39(4):423-430
- CONCLUSIONS: Inside out mastoidectomy is a better alternative in canal wall down procedures as it not only clears the disease from the middle ear cleft, but also leaves behind a small postoperative cavity, which will preserve the hearing, decrease the cavity problems and increase the quality of life of such patients.

The external auditory canal (EAC) is an osseocartilaginous structure extending from the auricle to the eardrum, which can be affected by congenital, inflammatory, and neoplastic diseases, thus reconstructive materials are needed. Current biomaterial-based approaches for the surgical reconstruction of EAC posterior wall still suffer from resorption (biological) and extrusion (synthetic). In this study, 3D fiber deposited scaffolds based on poly(ethylene oxide terephthalate)/poly(butylene terephthalate) were designed and fabricated to replace the EAC wall. Fiber diameter and scaffold porosity were optimized, leading to 200 ± 33 µm and 55% ± 5%, respectively. The mechanical properties were evaluated, resulting in a Young's modulus of 25.1 ± 7.0 MPa. Finally, the EAC scaffolds were tested in vitro with osteo-differentiated human mesenchymal stromal cells (hMSCs) with different seeding methods to produce homogeneously colonized replacements of interest for otologic surgery. This study demonstrated the fabrication feasibility of EAC wall scaffolds aimed to match several important requirements for biomaterial application to the ear under the Tissue Engineering paradigm, including shape, porosity, surface area, mechanical properties and favorable in vitro interaction with osteoinduced hMSCs. This study demonstrated the fabrication feasibility of outer ear canal wall scaffolds via additive manufacturing. Aimed to match several important requirements for biomaterial application to ear replacements under the Tissue Engineering paradigm, including shape, porosity and pore size, surface area, mechanical properties and favorable in vitro interaction with osteo-differentiated mesenchymal stromal cells.

The incidence of intradermal nevus in the external auditory canal is uncommon. We herein are describing a case of 60-year-old lady who presented with foreign body sensation in the right external ear canal (EAC) with mild discomfort and ear bleed during ear picking. Otoscopic examination revealed hyperpigmented mass on the floor of the outer two third of EAC. Complete excisional biopsy of the mass resulted in histopathology findings of intradermal nevus. Despite the fact that the disease is not alarming, the possibilities of benign melanocytic nevi transformation into malignant lesions such as melanoma need to be ruled out.
