1 Introduction

onsillectomy is the most common surgical procedure per-ormed in the ear nose and throat practice It is mostrequently perormed via cold dissection both in the pediatricandadult agegroup worldwide Many hotdissection methods

have been de1047297ned as an alternative to the cold dissectionHot dissection methods include bipolar andor monopolarelectrocautery radiorequency harmonic scalpel coblatorand thermal welding system (WS) [983089] Previous studieshave reported and compared the outcomes o radiorequencyWS cold knie or monopolar electrocautery in terms o posttonsillectomy bleeding and pain [983090] Termal welding isthe technique that simultaneously uses heat and pressure toprovide coagulation In a study conducted on adults ton-sillectomies perormed by WS and bipolar electrocautery werecompared in terms o intraoperative bleeding operationduration postoperative pain time to regain normal dietand postoperative bleeding [983091 983092] Multiparametric studies

comparing a ew methods have been conducted also in thepediatric age group [983093] However studies comparing adultand pediatric patients in terms o postoperative bleeding andpain ollowing tonsillectomy perormed by WS are limitedTe aim o the present study was to investigate and compare

the postoperative bleeding and pain ollowing tonsillectomy perormed by WS in the pediatric and adult patients

4 Discussion

onsillectomy techniques have been compared through var-ious parameters in the previous studies Tese comparisonshave been perormed only among pediatric andor adultage groups [983091ndash983093] Tere have also been studies comparing

various techniques in both age groups [983090 983097] However limitednumber o studies in the literature has compared adult andpediatric patients in terms o the same technique In thepresent study we compared the adult and pediatric patientsin terms o postoperative bleeding and pain ollowing tonsil-lectomy perormed WS

Karatzias et al [983097] reported no postoperative bleedingafer tonsillectomy perormed by WS in the adult andpediatric patients Moreover operation duration was shorterin the pediatric patients than in the adults In that particularstudy 983091 adult patients developed intraoperative bleedingrom the tonsillar artery in the inerior pole region andthe bleeding was controlled by bipolar electrocautery Inthe present study postoperative bleeding was developed in

both groups being signi1047297cantly more prevalent in the adultage group Karatzias et al [983097] mentioned that intraoperativebleeding requires additional coagulation o the large vesselsand additional suture techniques particularly in the adultpatients Tis result was consistent with the result o thepresent study which revealed more prevalent postoperativebleeding among adult patients

Stavroulaki et al [983089] compared cold dissection and WSin the adult patients and showed signi1047297cantly lower painscores in the WS group particularly within the 1047297rst ourpostoperative days In the present study pain scores wereound higher in the adult age group as compared to thepediatric age group Stavroulaki et al [983089] attributed this result

to the act that WS was simple and aster and producedmuch lower collateral thermal damage as compared to themonopolar or bipolar electrocautery Tey ound no signi-icant difference between these two techniques in terms o postoperative bleeding Postoperative bleeding was observedonly in 983091 patients in the cold dissection group o whom 983090 hada history o peritonsillar abscess

Karatzanis et al [983089983088] perormed a comparative study inthe adultsusing WS andLigaSuremethod andoundno di-erence between the techniques in terms o the intraoperativebleeding and mean operation duration On the other handthe mean pain score was signi1047297cantly lower in the WS groupon each postoperative day as compared to that in the LigaSure

group Moreover they noted late postoperative bleeding in 983089patient in the WS group and in 983090 patients in the LigaSuregroup Tus they concluded that both techniques provideadequate homeostasis in the adult patients Te present study showed higher incidence o postoperative bleeding amongadult patients as compared to that in the WS group o Karatzanis et al [983089983088]

In their comparative study conducted on adult patientsusing WS and bipolar electrocautery Karatzias et al [983091]reported that 983097 patients presented with late postoperativebleeding o whom 983092 were in the WS group and 983093 were inthe bipolar electrocautery group Tey noted no bleeding inthe mouths or pharynxes o 983090 patients in the WS group and

983091 patients in the bipolar electrocautery group andthe patientswere discharged Te remaining 983089 (983089983090) patient in the WSgroup and 983091 (983092983091) patients in the bipolar electrocautery group were hospitalized because o bleeding in the oral cavityBleeding was controlled under general anesthesia in 983089 patientin the bipolar electrocautery group In the present study

postoperative bleeding was observed in 983095 adult patients o whom 983092 (983089983089983092) were hospitalized due to bleeding in theoral cavity and were discharged without any interventionBleeding was controlled under general anesthesia in theremaining 983091 (983096983093) patients

In their multiparametric study Chimona et al [983093] com-pared cold knie radiorequency and WS in the childrenundergoing tonsillectomy and they reported that postopera-tive pain was signi1047297cantly lower in the cold knie procedureTey ound no signi1047297cant difference between these threemethods in terms o late postoperative bleeding In thatparticular study the incidence o postoperative bleeding was983090983090983091 whereas it was 983094983089983096 among pediatric age group inthe present study O the pediatric patients withpostoperativebleeding 983090 (983089983089983090) required bleeding control under generalanesthesia Chimona et al [983093] indicated that the incidence o posttonsillectomy bleeding was low in their study and they attributed this result to the experience o the surgeons whomperormed the procedure as well as to the time that they recommended to the children to start their normal diet andactivity

Michel et al [983090] conducted a study on 983089983088983088 patientsand divided them into two subgroups according to theirages patients between 983090 and 983089983090 years o age constitutedyounger group and patients between 983089983091 and 983092983095 years o ageconstituted older group Tis study which is the only study in the literature similar to the present study introduced thepreliminary results about saety efficacy and morbidity o WS used or tonsillectomy and compared the results withthose o other total tonsillectomy techniques in the literatureIn that particular study the mean pain score during healingwas 983090983088 in the younger group and 983091983089 in the older groupTeseresults were consistent with the results o the present studythe postoperative pain score was signi1047297cantly lower in thepediatric patients compared to that in the adults Moreoverin that particular study the incidence o late postoperativebleeding was the same both in the younger and older groups(983090) Te incidence o late postoperative bleeding in thepresent study was 983094983089983096 in the pediatric age group and 983090983088in the adult age group

In the literature Lee et al [983089983089] reported that there wasno difference between cold and hot dissections in termso the incidence o secondary bleeding in the pediatricage group Nevertheless in their study Michel et al [983090]perormed a literature review and reported the incidences o latepostoperative bleeding or different techniques as ollows983096983094 (1038389 = 1455) or electrodissection 983091983097 (1038389 = 1829) orcoblation 983090983096 (1038389 = 468) or harmonic scalpel and 983089983093(1038389 = 1610) or cold knie In the present study the incidenceo late postoperative bleeding was 983094983089983096 in the pediatric agegroup and 983090983088 in the adult age group

onsillectomy techniques have been compared through var-ious parameters in the previous studies Tese comparisonshave been perormed only among pediatric andor adultage groups [983091ndash983093] Tere have also been studies comparing

various techniques in both age groups [983090 983097] However limitednumber o studies in the literature has compared adult andpediatric patients in terms o the same technique In thepresent study we compared the adult and pediatric patientsin terms o postoperative bleeding and pain ollowing tonsil-lectomy perormed WS

Karatzias et al [983097] reported no postoperative bleedingafer tonsillectomy perormed by WS in the adult andpediatric patients Moreover operation duration was shorterin the pediatric patients than in the adults In that particularstudy 983091 adult patients developed intraoperative bleedingrom the tonsillar artery in the inerior pole region andthe bleeding was controlled by bipolar electrocautery Inthe present study postoperative bleeding was developed in

both groups being signi1047297cantly more prevalent in the adultage group Karatzias et al [983097] mentioned that intraoperativebleeding requires additional coagulation o the large vesselsand additional suture techniques particularly in the adultpatients Tis result was consistent with the result o thepresent study which revealed more prevalent postoperativebleeding among adult patients

Stavroulaki et al [983089] compared cold dissection and WSin the adult patients and showed signi1047297cantly lower painscores in the WS group particularly within the 1047297rst ourpostoperative days In the present study pain scores wereound higher in the adult age group as compared to thepediatric age group Stavroulaki et al [983089] attributed this result

to the act that WS was simple and aster and producedmuch lower collateral thermal damage as compared to themonopolar or bipolar electrocautery Tey ound no signi-icant difference between these two techniques in terms o postoperative bleeding Postoperative bleeding was observedonly in 983091 patients in the cold dissection group o whom 983090 hada history o peritonsillar abscess

Karatzanis et al [983089983088] perormed a comparative study inthe adultsusing WS andLigaSuremethod andoundno di-erence between the techniques in terms o the intraoperativebleeding and mean operation duration On the other handthe mean pain score was signi1047297cantly lower in the WS groupon each postoperative day as compared to that in the LigaSure

group Moreover they noted late postoperative bleeding in 983089patient in the WS group and in 983090 patients in the LigaSuregroup Tus they concluded that both techniques provideadequate homeostasis in the adult patients Te present study showed higher incidence o postoperative bleeding amongadult patients as compared to that in the WS group o Karatzanis et al [983089983088]

In their comparative study conducted on adult patientsusing WS and bipolar electrocautery Karatzias et al [983091]reported that 983097 patients presented with late postoperativebleeding o whom 983092 were in the WS group and 983093 were inthe bipolar electrocautery group Tey noted no bleeding inthe mouths or pharynxes o 983090 patients in the WS group and

983091 patients in the bipolar electrocautery group andthe patientswere discharged Te remaining 983089 (983089983090) patient in the WSgroup and 983091 (983092983091) patients in the bipolar electrocautery group were hospitalized because o bleeding in the oral cavityBleeding was controlled under general anesthesia in 983089 patientin the bipolar electrocautery group In the present study

postoperative bleeding was observed in 983095 adult patients o whom 983092 (983089983089983092) were hospitalized due to bleeding in theoral cavity and were discharged without any interventionBleeding was controlled under general anesthesia in theremaining 983091 (983096983093) patients

In their multiparametric study Chimona et al [983093] com-pared cold knie radiorequency and WS in the childrenundergoing tonsillectomy and they reported that postopera-tive pain was signi1047297cantly lower in the cold knie procedureTey ound no signi1047297cant difference between these threemethods in terms o late postoperative bleeding In thatparticular study the incidence o postoperative bleeding was983090983090983091 whereas it was 983094983089983096 among pediatric age group inthe present study O the pediatric patients withpostoperativebleeding 983090 (983089983089983090) required bleeding control under generalanesthesia Chimona et al [983093] indicated that the incidence o posttonsillectomy bleeding was low in their study and they attributed this result to the experience o the surgeons whomperormed the procedure as well as to the time that they recommended to the children to start their normal diet andactivity

Michel et al [983090] conducted a study on 983089983088983088 patientsand divided them into two subgroups according to theirages patients between 983090 and 983089983090 years o age constitutedyounger group and patients between 983089983091 and 983092983095 years o ageconstituted older group Tis study which is the only study in the literature similar to the present study introduced thepreliminary results about saety efficacy and morbidity o WS used or tonsillectomy and compared the results withthose o other total tonsillectomy techniques in the literatureIn that particular study the mean pain score during healingwas 983090983088 in the younger group and 983091983089 in the older groupTeseresults were consistent with the results o the present studythe postoperative pain score was signi1047297cantly lower in thepediatric patients compared to that in the adults Moreoverin that particular study the incidence o late postoperativebleeding was the same both in the younger and older groups(983090) Te incidence o late postoperative bleeding in thepresent study was 983094983089983096 in the pediatric age group and 983090983088in the adult age group

In the literature Lee et al [983089983089] reported that there wasno difference between cold and hot dissections in termso the incidence o secondary bleeding in the pediatricage group Nevertheless in their study Michel et al [983090]perormed a literature review and reported the incidences o latepostoperative bleeding or different techniques as ollows983096983094 (1038389 = 1455) or electrodissection 983091983097 (1038389 = 1829) orcoblation 983090983096 (1038389 = 468) or harmonic scalpel and 983089983093(1038389 = 1610) or cold knie In the present study the incidenceo late postoperative bleeding was 983094983089983096 in the pediatric agegroup and 983090983088 in the adult age group

In the literature Lee et al [983089983089] reported that there wasno difference between cold and hot dissections in termso the incidence o secondary bleeding in the pediatricage group Nevertheless in their study Michel et al [983090]perormed a literature review and reported the incidences o latepostoperative bleeding or different techniques as ollows983096983094 (1038389 = 1455) or electrodissection 983091983097 (1038389 = 1829) orcoblation 983090983096 (1038389 = 468) or harmonic scalpel and 983089983093(1038389 = 1610) or cold knie In the present study the incidenceo late postoperative bleeding was 983094983089983096 in the pediatric agegroup and 983090983088 in the adult age group
