incidence of concha bullosa and its association with chronic rhinosinusitis deviated nasal septum and osteomeatal complex obstruction

To determine the incidence of concha bullosa and its association with deviated nasal septum, obstruction of osteomeatal complex and chronic rhinosinusitis. Retrospective study. Otorhinolaryngology, head and neck surgery department. Nine hundred thirty-one consecutive paranasal sinus CTs taken between 2008 and 2010 were reviewed; 347 cases of concha bullosa [CB] were identified. Those cases were reviewed radiologically for the presence and severity of deviated nasal septum, obstruction of the osteomeatal complex and sinus disease. The significance of associations was tested using chi-square or Fischer exact tests. Patient's age ranged from 8 to 84 years with a mean age of 32.6 years. Two hundred twenty-nine [66%] were females. Three hundred forty-seven [37.3%] had CB and 224 [64.6%] had deviated nasal septum with CB. No association between a unilateral or dominant CB and ipsilateral or contralateral DNS and ipsilateral or contralateral maxillary, ethmoid and sphenoid sinus involvement was found. Similarly, there was no association with disease in the ipsilateral or contralateral osteomeatal complex. Although concha bullosa is a common occurrence in the nasal cavity, no statistically significant relationships between the presence of concha bullosa, deviated nasal septum, obstruction of osteomeatal complex and sinus disease was found

role of nasal allergy in otitis media with effusion

To evaluate the association of allergy and otitis media with effusion [OME], in children. Case-control. King Abdul-Aziz University Hospital, Saudi Arabia. Fifty-two children aged 1 to 15 years with diagnoses of recurrent or persistent secretory otitis media admitted for myringotomy and Grommet insertion from January 2008 to June 2009 [OME group] were included in the study. Children of similar age who attended the pediatric surgical unit during the same period for different pediatric surgical procedures other than ENT surgeries were matched using gender and age [control group]. History of allergic rhinitis and results of RAST [radioallergosorbent test] were documented. Fifty-two children had OME, all [100%] had positive history of allergic rhinitis and 31 [81.6%] had RAST positive, the test was performed in 38 children. In the control group, no allergic rhinitis history was obtained and only seven [23%] were RAST positive, the test was performed in 31 children. This study shows that RAST positive is higher in OME group compared to control. In addition, history of allergy is higher in OME group compared to the controls
