Problem Unexplained persistent or recurrent bacterial pharyngitis in some patients who suffer from infected middle ear cleft. Methods Bacteriological swabs were obtained from both the ears and the pharynx of 37 cases with chronic otorrhea and perforation, whom complain of recurrent or persistent sore-throat. Then isolation and identification of the micro-organisms were done. This included examination of direct Gram stained films and cultures. Isolated Gram negative bacilli were subjected to further identification by the biochemical reactions and antibiotyping. Identical isolates from the same patient (ear and pharyngeal swabs) were subjected to further identification by genotyping using the pulsed field gel electrophoresis technique. Results 6 cases (16%) showed identity in phenotypes and genotypes for ear and pharyngeal samples from the same patient. All pharyngeal isolates were Gram negative organisms. 4 of them were Pseudomonas aeruginosa, 1 was Proteus sp., and 1 was Escherichia coli. All of these 3 species are not known to be among the primary organisms which may cause pharyngitis. Conclusion Bacterial pharyngitis in patients with chronically infected middle ear cleft may be attributed to the same organism invaded the middle ear mucosa. Also this study highlights some organisms as a pharyngeal invaders although they are not among the previously documented causatives of bacterial pharyngitis. But the study do not confirm the method of spread of these organisms and whether this was directly via the eustachian tube. Significance The study correlates the causative organism of the middle ear infection and that infected the pharyngeal mucosa utilizing the advanced bacteriological identification and genotyping techniques.

Carcinoid tumour is one of the rarest middle-ear neoplasms. We describe here a case of carcinoid tumour of the middle-ear cleft that presented with aural as well as systemic symptoms. Diagnostic difficulty was encountered using light microscopy, but electron microscopy revealed the neurosecretory granules.

Middle Ear Cleft

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.

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.

Petromastoid Canal

The embryology and anatomy of the petromastoid canal is reviewed. This structure may be responsible for the passage of some infections of the middle ear cleft into the posterior fossa. It also transmits important blood vessels to a portion of the bony labyrinth, to the facial canal, and to the mucosa of the mastoid air cell system.

AbstractA 64-year-old man with right aural discharge presented complaining of progressive deafness. Other otological symptoms were absent and specifically there was no seventh nerve paresis. A right aural polyp was identified and biopsied. Histology showed the polyp to be a schwannoma.Subsequent temporal bone computed tomography showed expansion of the distal facial canal. At operation, the schwannoma filled the middle ear cleft and extended from the genu to the region of the stylomastoid foramen. The floor of the middle ear had been eroded, exposing the jugular bulb.Facial paresis is the usual presenting feature of a facial schwannoma, while deafness, ageusia and reduced lacrimation are variable, dependent upon the site of the lesion. The absence of facial palsy as a presenting feature is very rare and this case illustrates the need for histological examination of all abnormal aural material.
