A Cadaveric Study of Anatomical and Radiological Correlation of Mastoid Air Cells System in Relation to its Morphology.

A cadaveric study to know the anatomical and radiological correlation between the mastoid air cell system in relation to its volume and morphology. This is a rare and one of its kind of cadaveric study on temporal bone in which comparison of pre dissection and post cortical mastoidectomy dissection on x-ray mastoid in relation to their dimensions. To study the anatomical and radiological correlation of mastoid air cell system in relation to its morphology using pre and post dissection x-ray measurements and dissection method. 30 adult cadaveric, temporal bone cortical mastoidectomy dissections were performed and X-ray mastoid with a pre and post mastoid dissection measurements using vernier caliper was done. Further 3-D analysis of volume of mastoid cavity compared with a post dissection digital radiographic measurements was carried out. On statistical analysis, mean surface area of MACS, shortest length between sigmoidsinus and posterior wall of EAC, also shortest distance between dural plate and mastoid tip, in pre and post dissection x-ray mastoid and in direct mastoid cavity measurements were not found to be significant. Mastoidectomy being the treatment of choice in day to day practise in many cases this study hopes to add up to the present understanding for the MACS dynamics and assesses the possible anatomical variations that can exist. This study helps us to find the approximate time required for surgery to perform cortical mastoidectomy.

Disparate Presentations of Retropharyngeal Abscess: An Experience From a Tertiary Care Centre.

To discuss the varied presentations, diagnosis, and prompt management of retropharyngeal abscess for academic importance. A retrospective study was conducted in the Department of Otorhinolaryngology and Head and Neck Surgery in Belagavi district of Karnataka. Six cases of varied age group with diagnosis of retropharyngeal abscess were studied during two-year period from January 2019 to January 2021. Thorough assessment of all cases was done which included symptoms at the time of presentation, clinical examination findings, imaging studies and laboratory results, medical and surgical interventions. Six patients (4 males, 2 females) were diagnosed as having Retropharyngeal abscess. Youngest age of presentation was 2 month infant. The most common symptoms at presentation included fever and odynophagia seen in all six patients. The clinical examination revealed bulge in posterior pharyngeal wall in all cases, cervical lymphadenopathy in one case, drooling of saliva in three and stridor in one patient, diffuse neck swelling in two ptatients, and trismus in two patients. Contrast Enhanced Computerized Tomographic (CECT) scanning was performed in five patients and one patient underwent Magnetic Resonance Imaging (MRI). The abscess was surgically drained in all patients and received intravenous antibiotics after which there was significant improvement. Retropharyngeal space infection if left untreated, they carry the potential to cause life-threatening complications and death. Although with availability of broad-spectrum antibiotics, the mortality rate is low, appropriate and successful management requires a thorough understanding of the anatomy of the neck, knowledge of usual causative organisms and appropriate medical and surgical management.
