Abstract
Summary Nasal turbinates are important anatomical and physiological landmark of the lateral nasal wall. Concha Bullosa (pneumatized turbinate) is a phenomenon which is considered one of the most common anatomical variants of the sinonasal region usually occurring at the middle turbinates more than other nasal turbinates. The exact reason of the pneumatization of the middle turbinate in some people but not in others, is still unclear, but this phenomenon has been shown to be of clinical importance as its incidence was about 38% of people who had been prepared for radiological nasal examination, according to somestudies. The vast majority of cases are asymptomatic, but the excessive enlargement of the middle turbinate pneumatization can lead to persistent nasal symptoms not responding to various medications. It may also impair the access of intraoperative nasoendoscopy. The definitive treatment of these cases ismainly surgical by various techniques as ; lateral laminectomy (partial turbinectomy), conchoplasty (turbinoplasty) and othertechniques. The aim of this study was to compare between lateral laminectomy and conchoplasty , as regard their outcome results . This prospective study was carried out on 50 patients aged over 18 years who have clinical and radiological evidence of symptomatic middle turbinate concha bullosa when they presented to the outpatient clinic of Otorhinolaryngology department of Tanta university hospital from August 2020 till January 2022. Patients were divided equally into group A for lateral laminectomy and group B for conchoplasty.
