Our results suggest that clinical signs of infection are lacking in patients with secondary tonsillectomy bleeding. Correspondingly the routine use of antibiotics should be questioned for secondary tonsillectomy haemorrhage.

demonstrated asymmetric extension. Either one or both anterior ethmoidal arteries were exposed in 65.4% of the cases with supraorbital ethmoidal cells. Since more posterior extension of supraorbital ethmoidal cells is rare, the posterior ethmoidal artery was exposed in only 15 of the cases.Conclusions: The presence of supraorbital ethmoidal cells is not rare and evaluation of their extension is especially important to avoid complications during endoscopic sinus surgery. When the cells extend beyond the ethmoidal arteries, the high ethmoid roof will make these vessels open to laceration during surgical procedure. In order to avoid complications during endoscopic sinus surgery, thorough investigation of paranasal sinus CT scans is crucial.

Malignant perip heral nerv e shea th tumors of the nos e and paranasal sinuses are extreme ly uncomm on. We report the case ofa 65-y ear-old woman who presented with a rapid emergence of "nasal polyps " that comp letely obstructed her nasalpassag es. Six years earliet; she hadbeen asse ssed else where f or nasal polyps. A t presentation, the patient exhibited grosspolypo sis, with lesionsprotrudingfrom both nostrils. Histology confirmed a diagnosis ofa malignant periph eralnerve sheath tumor: This case demonstrates that symp toms ofnasal obstruction are not always secondary to simp le causes. We discuss the clinical pi cture ofnasal and paranasalmalignant p eriph eralnerve shea th tumor; its pathology, and its treatm ent.

Ectopic cervical thymus should always be considered in the differential diagnosis of a paediatric neck lump. The diagnosis can often be confirmed by cytology and radiology prior to surgical excision.
