In even more severe cases the infection may spread to the brain itself causing an "abscess", or collection of pus. These problems are life threatening and require prompt and aggressive treatment. Complications of sinusitis : Dr Nishit Shah Complications of sinusitis flare-ups of the sinusitis can lead to asthma attacks Sinusitis may diminish the senses of smell and taste Infections that involve either the carotid artery or cavernous sinus may lead to aneurysms or infected blood clots in the intracranial cavity, both of which are potentially fatal What is FESS : Dr Nishit Shah What is FESS Anatomy Physiology Aetiology Pathology Indications for ESS : Dr Nishit Shah Indications for ESS Chronic sinusitis Acute sinusitis Sphenoid pathology Polyposis Mucocoele/ Pyocoele Fungal sinusitis Allergic fungal sinusitis Septal spur Concha bullosa Asthma/ URTI Cystic fibrosis / AIDS Epistaxis Barotrauma FB, Rhinolith FESS : Dr Nishit Shah FESS Uncinectomy Ethmoidectomy Maxillary Sinus Frontal Sinus Sphenoid Sinus FESS - Sinusitis : Dr Nishit Shah FESS - Sinusitis Extended Endoscopic Surgery : Dr Nishit Shah Extended Endoscopic Surgery CSF rhinorrhoea Pituitary surgery Nasal tumours / mass Nasopharynx tumours Choanal atresia Anterior skull base Clivus tumours Endoscopic DCR Orbital decompression Orbital complications Optic nerve decompression Orbital tumours Vidian neurectomy Cavernous sinus Complications of FESS : Dr Nishit Shah Complications of FESS Bleeding Synechae Anosmia Diplopia Blindness CSF leak Epiphora Facial Pain Toothache Antrostomy Closure Subcutaneous Emphysema Nasal Polyps : Dr Nishit Shah Nasal Polyps 2% of the population They are fluid filled sacs composed of an edematous tissue with infiltrating cells, including mast cells, eosinophils, lymphocytes and plasma cells surrounded by a ciliated airway epithelium- no true evidence of seromucinous glands An enigma !!!
