Aim. The aim of our ­work was to ­study the ­space occu­py­ing ­lesions in the parapharyngeal ­space and how CT ­scan can ­help in selec­tion of appro­pri­ate sur­gi­cal approach­es, on the ­basis of the ana­tom­i­cal rela­tion of the ­tumour ­with the ­vital struc­tures, assess­ing its ­nature and to ­plan its sur­gi­cal ­approach.
Methods. The par­a­pha­ryn­geal ­space is a ­deep ­space sit­u­at­ed on ­either ­side of ­neck. Clinical assess­ment, radiological asso­ci­a­tion and sur­gi­cal approach­es ­have ­been dis­cussed in 26 ­patients ­worked up and oper­at­ed in the Depart­ment of Otorhinolaryn- gology and Head Neck Sur­gery of the Postgraduate insti­tute of med­i­cal edu­ca­tion and ­research, Chandigarh (India). This was a pros­pec­tive ­study con­duct­ed in our depart­ment ­over a period of 1 ­year. The cas­es ­were select­ed ­from the depart­ment ­from October 2000 and September 2001. The cas­es who had exten­sive inop­er­able malig­nant ­tumours ­with intra­cra­ni­al exten­sion, malig­nan­cies of nasoph­a­rynx extend­ing ­into PPS ­were not includ­ed in ­this ­study. Detailed ­work up of all the ­patients includ­ing radio­log­i­cal inves­ti­ga­tions was con­duct­ed. All ­patients under­went sur­gi­cal exci­sion of the ­tumour.
Results. Lesions in the par­a­pha­ryn­geal ­space are ­rare and com­prise ­only 0.5% of head and neck neo­pla­sia. The major­ity of ­lesions are ­benign and ­only a few are malig­nant. Tumours in ­this ­space orig­i­nate ­from var­i­ous tis­sues ­present in ­this ­space, occa­sion­al­ly exten­sion ­from neigh­bour­ing struc­tures and rare­ly ­through ­blood or lym­phat­ic.
