BACKGROUND: Nasal and paranasal cavities are supposed to contribute substantially to the vocal tract resonator properties. However, their acoustical effects as well as the effects of sinus surgery on the voice remain unclear. In this work we investigate resonance phenomena of paranasal sinuses prior to and after various rhinosurgical procedures in cadaveric human sinonasal tracts and corresponding 3D casts. METHODOLOGY: Nasal and paranasal cavities of formalin-preserved cadavers and corresponding 3D replicas were excited by sine-tone sweeps from an earphone placed in the epipharynx...

Balloon dilatation of sinus ostia (sinuplasty) was introduced in 2005 as a treatment for Chronic Rhinosinusitis (CRS).(1) It has been described as a 'transition space' tool for the ethmoidal infundibulum and frontal recess.(1) It can been used as a lone procedure or in combination with functional endoscopic sinus surgery (FESS) as a "hybrid" technique. Balloon sinuplasty applies the Seldinger technique to cannulate and dilate stenosed or occluded sinus ostia re-establishing drainage pathways and ventilation...

Sinonasal glomangiopericytoma is a benign rare tumour of pericytes that accounts for less than 0.5% of all sinonasal tumours. It is an indolent tumour with a macroscopic appearance of common inflammatory polyps. We report the case of a 55-year-old male who presented with right nasal obstruction. CT and MRI examinations demonstrated a soft-tissue mass that obstructed mainly the right nasal cavity. Biopsy revealed glomangiopericytoma. The tumour was treated with preoperative embolisation followed by complete endoscopic resection...

BACKGROUND: Resection of extensive skull base lesions often necessitates relatively large dural openings and arachnoid, resulting in skull base defects with the potential for a post-operative cerebrospinal fluid (CSF) leak. A nasoseptal flap (NSF) is a vascularized graft which has greatly diminished the incidence of CSF leak. Annealing of flaps against the ventral skull base can be tenuous within the first few days after surgery. We report the use of sphenoid sinus fat packing as a buttress to support the nasoseptal flap during skull base reconstruction...
