ABSTRACT The external auditory canal (EAC) is formed by lateral cartilaginous and medial bony part. The stenosis of EAC is narrowing of the width of the EAC, i.e. either caused by congenital or acquired causes. Myringosclerosis is a condition caused by calcification of tissues in the tympanic membrane and ossification is a special form of fibrosis due to the long-term, irreversible continued inflammation in the middle ear cleft. We are presenting rare case of idiopathic tympanic membrane ossification with generalized stenosis of EAC in 29-year-old patient. How to cite this article Verma H, Dass A, Singhal SK, Gupta N.

Bilateral congenital mesotympanic cholesteatoma is a very rare disease. It can present differently from ordinary congenital cholesteatoma. We report a case of bilateral congenital cholesteatoma diagnosed at age of 22 years old. She presented with bilateral intermittent ear discharge since 10 years old that worsening two weeks prior to her presentation to our clinic and associated with bilateral reduced hearing. Clinically there was intact tympanic membrane with retraction of the mesotympanic area with present of mass medial to tympanic membrane. CT scan imaging showed there was soft tissue in the bilateral middle ear cavity with intact scutum and ossicles. Patient undergone canal wall down procedure and the diagnosis of congenital mesotympanic cholesteatoma was confirmed with present of cholesteatoma sac at the posterosuperior part, as opposed to anterosuperior quadrant, where the common site for congenital cholesteatoma.Bangladesh Journal of Medical Science Vol.17(2) 2018 p.307-310

Endaural incisions provide a cosmetic approach to the middle-ear cleft, tympanic membrane for myringoplasty, and attic and antrum for small cavity mastoidectomy. These wounds have traditionally been closed with sutures, but platelet or fibrin adhesives provide an alternative. However, discomfort at the time of suture removal, particularly in children, and the risk of transmission of blood-borne infections in gels are limitations to these wound closure techniques. This paper describes our experience with Histoacryl® glue (butyl-2-cyanoacrylate) in closing endaural incisions.

Abstract Background Simple closure of tympanic membrane perforation is not a successful myringoplasty. It has to obey a lot of functional aspects of the middle ear cleft. Certain factors play a role in failure cases. The endoscopic functional myringoplasty or tympanoplasty is a clear visualization of all the parts of the middle ear; examination and removal of the disease from the hidden parts of the middle ear, examination of inter-attico-tympanic diaphragm; and removal of blocks, if any, in isthmus, to reestablish the gas exchange pathways and finally preserve the middle ear mucosa at maximum to further restore the ventilation. Methods Endoscopic tympanoplasty was performed in 100 patients with large tympanic membrane perforations and patent eustachian tube, using 4-mm “0” and “45” degree endoscopes by proper visualization of the tympanic diaphragm and isthmus in every patient and clearing its blockage if present. Results Among the 100 patients, 78 had epitympanic diaphragm blockage at the level of isthmus, 5 patients were found with closed tensor tympani folds, both vertical and horizontal without any ventilatory routes in them. Although in all the patients the eustachian tube was patent, we found majority of them had a dysventilation at the level of the epitympanic diaphragm. Thus, by performing endoscopic ventilatory pathway clearance and tympanoplasty, we achieved 94% positive results. Conclusion Epitympanic diaphragm is a functional barrier between upper and lower compartments of the middle ear cleft, which play important role in the ventilation and partial pressure regulation, blockage of its isthmus may lead to tympanic membrane retractions and perforations. With the aid of endoscopes of various degrees, removing any pathological blocks, recreating proper ventilation, reestablishing gas exchange mechanism, and maximum preservation of normal mucosa for the gas exchange are the aims of an endoscopic functional tympanoplasty procedure.

Objective. We report an extremely rare case of ganglioneuroma involving the external auditory canal and middle ear. Case Report. Ganglioneuromas are rare benign mature tumors thought to originate from sympathetic ganglions, with the highest incidence in the retroperitoneum, adrenal medulla, and posterior mediastinum. We present a case of ganglioneuroma of the external auditory canal and middle ear. At the age of 12 months, the patient was diagnosed with neuroblastoma stage IV with metastasis to the squamous temporal bone, bone marrow, and skull base. He received a high-risk protocol regimen resulting in complete remission. The patient later presented with recurrent right ear discharge at the age of six years and was diagnosed with ganglioneuroma of external auditory canal and middle ear after appropriate investigations. We report in this article the clinical presentation, investigations, surgical intervention, and follow-up. Conclusion. After the literature review and to our knowledge, this is the first reported case of its kind. Ganglioneuroma maturing from neuroblastoma is one of the theories describing pathophysiology of the disease. Ganglioneuroma should be considered in the differential diagnosis of patients presenting with recurrent ear discharge and decreased hearing in treated cases of neuroblastoma with metastases to temporal bone.

ABSTRACT The external auditory canal is less susceptible to infections than the sensitive middle-ear cavity. Since recent research has provided insight to the production of potent antimicrobial peptides from various surface epithelia, we wanted to investigate whether protection of the external auditory canal in part could be explained by the production of human β-defensin-1 (HBD-1). This particular peptide is known to be constitutively expressed in various surface epithelia, such as airway, skin, and urogenital tissues. By reverse transcriptase PCR we demonstrate HBD-1 mRNA in the pars tensa and pars flaccida of the tympanic membrane and in the meatal skin. In situ hybridization studies localized the HBD-1 mRNA to the epidermal layer of these tissues. The HBD-1 transcripts were also evident in the sebaceous glands and in hair follicles of the meatal skin. In contrast, HBD-1 mRNA was not detected in the tympanal epithelium of the eardrum. The widespread presence of mRNA encoding for this broad-spectrum antimicrobial peptide in the meatal skin and tympanic membrane suggests that HBD-1 participates in the innate antimicrobial defense of the external auditory canal and middle-ear cavity.
