Background& Objective: Late – Stage Laryngeal Carcinoma (T3-T4 ) Has A High Incidence Of Cervical Metastasis . The Incidence Of Subclinical Metastasis Is Not Well Described In None Irradiation an‎d Irradiation Patients Initially Clinically T3,T4) With Negative Nodes Of The Neck ,And The Treatment Of These Patients Is Contraversal. Identify The Incidence Of Subclinical Metastatic Disease In (T3,T4) ) With Negative Nodes Of The Neck Undergoing Functional Neck Dissections With Laryngectomy. an‎d Identify The Incidence Of Subclinical Metastatic Disease In Those Patients Who Faild Radiotherapy. Are There Any Benefits Of Cts In Those Patients? .And What Is The Most Aproprait Therapy?. Materials & Methods: 48 (T3,T4) ) With Negative Nodes Of The Neck Patients Underwent Laryngectomy With Neck Dissection In Al Mowasat Hospital Between 1/1/2010-1/1/2012 . .Pathologic Study Of The Neck Dissection Specimens As Undertaken. Results: The Male To Female Ratio Was 9/1, With A Mean Age Of 62 Years ( Range ,47 To 92 Years ). ,Presence Of Subclinical Metastatic Disease In The Neck According To Stage Was As Follows : T3; 4 Out Of 27 ( 14.82 %), T4; 6 Out Of 21( 28.6 %). an‎d According To Radiation Was 5 Out Of 27 ( 18 % ), None Radiation Patients 5 Outof 21 ( 24 %). The Incidence Of Positive Node On Cts Was 6 Out Of 10( 37 %) In None Radiatin Patients , Subclinical Metastasis Was 3 Out Of 16 ( 18.75 % ) . The Incidence Of Positive Node On Cts Was 7 Out 0f 7 In Radiation Patients , Subclinical Metastasis Was 5 Out Of 7 (71.44 %). Conclusions: Subclinical Cervical Metastasis Present In T3,T4 With Negative Nodes Of The Neck Laryngeal Scc Patients Consequantly, (14.82 %-28.6% ). Radiation Has Small Affect On The Incedanse Subclinical Cervical Metastasis To Be Less.The Aproprait Therapy Of Patients Who Failed Radiotherapy an‎d There Is Node On Cts .The Functional Neck Dissection Should Be Done.. The Apropriat Therapy Of Those Patients Is Laryngectomy With Functional Neck Dissection Because There Are Subclinical Cervical Metastasis
