An Unusually Large Submandibular Sialolith: A Case Report.

Sialolithiasis is among the most common pathological conditions of the salivary glands. It is characterized by blockage of the salivary gland excretory duct or by the formation of calcareous concretions, resulting in salivary stasis and causing salivary gland swelling. Most sialoliths generally arise in the submandibular gland and duct.

Periapical Cyst Forming Cutaneous Sinus Tract: Unusual Presentation-Case Report.

A cutaneous sinus tract due to periapical cyst being very rare may easily be misdiagnosed, leading to incorrect treatment. Identifying the etiology is difficult, but it is the key to effective therapy. The case presented here is a cutaneous sinus tract in the nasolabial region of odontogenic origin.

Comparison of Otoacoustic Emission (OAE) and Brainstem Evoked Response Audiometry (BERA) in High Risk Infants and Children under 5 Years of Age for Hearing Assessment in Western India: A Modification in Screening Protocol.

There are very few studies from India, which have compared Otoacoustic Emission (OAE) and Brainstem Evoked Response Audiometry (BERA) as a screening modality for detection of hearing loss in children. With the aim of establishing some guidelines regarding the protocols for hearing loss assessment and preventive measures, the present study has been undertaken to compare OAE with BERA done simultaneously, in the diagnosis of paediatric hearing loss, and also to study associated risk factors for hearing loss in children of Rural Central India. Prospective observational study was carried out on 100 children (200ears) in age group of 0-5 years.

Supra-Threshold Hearing Sensitivity Disorders and Mild Permanent Hearing Loss: Neglected Cause of Hidden Hearing Loss and Speech Defects.

Supra-threshold disorders in the form of auditory neuropathy (AN)/auditory dys-synchrony (AD) or central auditory processing disorders (CAPD), a special type of retrocochlear hearing loss; and also children with mild permanent hearing loss (PHL), may be missed on current hearing protocols. Otoacoustic emissions (OAE) and Brain stem evoked response audiometry (BERA), are tests, when used in combination, can indirectly help diagnose the different types of hearing loss. To correlate the parental awareness and the pattern of hearing loss (HL) in children with/without auditory and/or speech problems, using both OAE and BERA as hearing tests for indirect identification of suprathreshold disorders and mild PHL.

Role of Eustachian Dysfunction and Primary Sclerotic Mastoid Pneumatisation Pattern in Aetiology of Squamous Chronic Otitis Media: A Correlative Study.

Squamous chronic otitis media (COM) implies formation of a retraction pocket (inactive form) or frank cholesteatoma (active form) in pars tensa or pars flaccida of tympanic membrane. A retraction pocket or frank cholesteatoma are believed to occur due to tubal dysfunction. The present study was undertaken to investigate the pattern of mastoid pneumatisation and Eustachian dysfunction by dynamic slow motion videoendoscopy (DSVE) in cases of both, active and inactive type of squamous chronic otitis media (COM).

Anatomical Study of the Facial Recess with Implications in Round Window Visibility for Cochlear Implantation: Personal Observations and Review of the Literature.

 Posterior tympanotomy through facial recess (FR) is the conventional and most preferred approach to facilitate cochlear implantation, especially when the electrode is inserted through the round window. The complications of the FR approach can be minimized by proper understanding of the anatomy of the FR.  The present study was undertaken to assess the various parameters of FR and round window visibility, which may be of relevance for cochlear implant surgery.

Study of Correlation of Pre-Operative Findings with Intra-Operative Ossicular Status in Patients with Chronic Otitis Media.

Introduction: Chronic otitis media (COM) has been broadly classified into mucosal and squamous subtypes. COM types are associated with erosion of the ossicular chain. The aim of the present study was to correlate the type of COM, the site of perforation/retraction, and the type of disease pathology with the pattern and degree of ossicular chain necrosis.

Applied anatomy of round window and adjacent structures of tympanum related to cochlear implantation.

Introduction: Various aspects of the round window anatomy and anatomy of posterior tympanum have relevant implications for designing cochlear implant electrodes and visualizing the round window through facial recess. Preoperative information about possible anatomical variations of the round window and its relationships to the adjacent neurovascular structures can help reduce complications in cochlear implant surgery.

Objective: The present study was undertaken to assess the common variations in round window anatomy and the relationships to structures of the tympanum that may be relevant for cochlear implant surgery.
