Introduction: The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratoryepitheliumin the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery....

background sphenoid sinus is surrounded by many vital vascular and nervous structures. in more than 20% of patients with chronic sinusitis, involvement of sphenoid sinus has been observed. besides, sphenoid sinus is an appropriate route to access anterior and middle cranial fossa in surgery. therefore, it is important to have an adequate knowledge about the contents of sphenoid sinus and its pr...

introduction:bleeding is a common concern during functional endoscopic sinus surgery (fess) that can increase the risk of damage to adjacent vital elements by reducing the surgeon’s field of view. this study aimed to explore the efficacy of topical tranexamic acid in reducing intraoperative bleeding. materials and methods:this double-blind, randomized clinical trial was conducted in 60 patients...

introduction: the aim of this study was to determine which technique of uncinectomy, classical or swing door technique.  materials and methods: four hundred eighty cases of sinusitis were selected and operated for functional endoscopic sinus surgery (fess). out of these, in 240 uncinectomies classical uncinectomy was done whereas in another 240 uncinectomies swing door technique was used. initi...

background and objective : given the importance of rapid diagnosis for fungal rhinosinusitis, this study aimed to evaluate the use of nested pcr to identify aspergillus and mucor species in clinical samples from patients with suspected fungal rhinosinusitis. methods : functional endoscopic sinus surgery specimens were collected from 98 patients with rhinosinusitis from 2012 to 2013. all samples...

  Chronic suppurative otitis media (CSOM) is a common childhood infectious disease in developing countries. It may be associated with various life threatening intra-cranial or extra-cranial complications. We report a 10 year-male child with a rare combination of right sided unsafe CSOM, mastoiditis, Bezold abscess, sigmoid and transverse sinus thrombosis, and bilateral abducens nerve palsy and ...
