Aim: To evaluate the role of newly created transcanal endoscopic antrostomy hole as a passage in restoring the aeration of epitympanum and mastoid antrum.Materials & Methods: Study design: Retrospective case series study. Study duration: From January 2013 to January 2014. Study place: Private tertiary care hospital. Patients: 27  ears of 23 adult patients (age ranging from 15years to 54years) underwent transcanal endoscopic tympanoplasty for their chronic middle ear diseases in presence of inflamed middle ear mucosa along with radiological shadows of stagnant fluid in their epitympanum and mastoid antrum. Structured three months follow-up was ensured in every case. Intervention: A hole was created at a selected site of posterior meatal wall purely through transcanal endoscopic approach that established direct communication between mastoid antrum and external auditory canal. Thereafter this newly created passage was used for three purposes- assessment of the condition of mastoid antrum, performing the water test for checking epitympanic patency and in few cases placement of temporary tube for postoperative ventilation and drainage of middle ear. Main out come measures: The feasibility, performance and management of transcanal endoscopic antrostomy hole as passage for reestablishing the aeration of epitympanum and mastoid antrum.Results: The chosen site for antrostomy hole was found effective and safe in providing convenient entrance into the mastoid antrum in every case in this study with out facing technical complexity and failure. Postoperative healing of skin over antrostomy hole was found complete in all ears without any inward growth of skin in to mastoid antrum. Available post operative CT scan imaging of temporal bones showed improved aeration in their epitympanum and mastoid antrum.Conclusions: The role of transcanal antrostomy hole has been proved worthy in restoring ventilation pathway to epitympanum and mastoid antrum during tympanoplasty. This antrostomy hole has the potentiality to be considered in future for placement of long term mastoid ventilation tube in order to treat persistent atelectatic middle ear.

AbstractThe first isolated case of agenesis of the mastoid antrum, previously only described in association with the congenital syndromes trisomy 13 and mandibulofacial dysostosis, is reported. The loss of this important surgical landmark may result in disorientation and iatrogenic trauma. The surgeon must be aware of its existence, and where it is suspected the middle fossa dura should be exposed and followed posteriorly until the lateral sinus is encountered.

AbstractA 53-year-old female patient who presented with recurrent meningitis as a result of a meningioma, is reported. The meningioma was found to be wholly contained within the left mastoid antrum. To our knowledge this is the first reported case of a meningioma localised to the mastoid antrum. The patient had been assessed in the ENT department on two separate occasions, 17 years and 19 years previously for nebulous symptoms related to the left ear which had cleared spontaneously. Following a second episode of pyogenic meningitis, both of which were associated with aural symptoms, radiological examination suggested an intramastoid pathology which prompted mastoid exploration. Histological examination of the mass confined to the mastoid antum provided the diagnosis of meningioma. There was no clinical or radiological evidence of extratemporal spread of tumour.

AbstractConjunctival innoculation is a previously unrecognized hazard for the otologist during mastoid surgery. This experiment assesses the spread of droplet contamination during temporal bone dissection. The results suggest that otologists and assistants should wear eye protection during exposure of the mastoid antrum by drilling.

Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood and adolescence. There are four histological types and among them the embryonic types are the most common. It can occur in any anatomic location, although when occurring in the head and neck region, it has an affinity to invade the cranial cavity. Patient was a 5 years old boy who was admitted with the complaints of pain and discharge from the ear, swelling on left side of the upper neck, and mastoid region and a fleshy mass protruding from the ear canal. The mass was confirmed to be Embryonal Rhabdomyosarcoma on histopathology. CT scan of the Head-Neck region, showed extension of the mass into infra-temporal fossa and in the mastoid antrum. After complete excision, the patient was referred to oncology deptt for consultation. The chemotherapy schedule comprised of Vincristine and Dactinomycine for 9-12 cycles. Otolaryngologists need to be aware of this rare condition as it may mimic the symptoms of CSOM or nasal polyp. And also long term followup is needed since recurrence can present several years after initial treatment.Bangladesh J Otorhinolaryngol; October 2015; 21(2): 127-131

We report on a female with oculo-auriculo-vertebral spectrum, low height, and on X-ray lambdoid suture synostosis, cerebral cyst/mild holoprosencephalia and cholesteatoma, and multiple abnormalities of bones of chondral origin. On the right side, maxillary, mandibular bones, external auditory canal, middle ear were hypoplastic as well as semicircular canal, cranial base, bones vestibule. On the left side, coclea, timpanic cavity, mastoid antrum were hypoplastic, while stapes was misshapen. Limbs bones were slender with thin metaphyses and some carpal bones were absent. Hand second phalanx was hypoplastic and fifth finger presented clynodactily. Lambdoid synostosis expressed membranous ossification abnormality. We hypothesize that during the blastogenesis a mutation of a factor responsible for abnormal generalized endochondral and connectival ossification (possibly fibroblast growth factor receptor) occurs.
