RESUMEN
Chronic Otitis Media-Squamosal type is an erosive process, which when confined to ossicular chain causes varying degrees of hearing impairment. As the disease progresses to involve surrounding vital structures, it causes various complications like facial palsy, vertigo, mastoid abscess, which are more common than the other intracranial complications, and require a definitive surgical intervention i.e., mastoidectomy at the earliest. A retrospective study on 60 patients who had been operated for squamosal type were analysed for the demographics, symptomatology, intraoperative extent of cholesteatoma, type of mastoidectomy done, various graft materials used for reconstruction, post operatively for graft uptake, hearing improvement and the results were analysed using ChOLE classification of cholesteatoma. Although Intact Canal Wall mastoidectomy had improved post op PTA values, there was no significant difference in the Air-Bone gap closure when Intact Canal Wall mastoidectomy was compared to Canal Wall Down Mastoidectomy.
RESUMEN
Vertigo is an illusion of motion, either of one self or of the environment. Vertigo in BPPV is a very devastating experience for the patient who experiences it. However, it can be reversible with vestibular rehabilitation, with very good results. A study on 72 patients attending Otoneurology clinic in our hospital, diagnosed as BPPV with history and examination were subjected to DHI (Dizziness Handicap Index) questionnaire prior to and after intervention and results were analyzed. BPPV is more commonly seen in elderly individuals above 45 yrs, females and posterior semi circular canal. A significant improvement was noted in all the three components of DHI index in patients treated with CRM (Canalolith Repositioning Manoeuver) when compared to the patients who received only reassurance. CRM is a very safe and effective treatment of BPPV which has the added advantage of being noninvasive procedure, with excellent results.
