    • Classifications in ENT Dr. MTD Lakshan MBBS, MS(Oto), DOHNS (UK), FEB ORL-HNS, FRCSEd ORL-HNS Consultant ENT and Head and Neck Surgeon DGH Hambantota
    • General Points• Cannot include all the classifications in a 1 hour presentation• Details of T staging of tumour sub-sites from TNM document e.g. Larynx, nasopharynx, thyroid etc• Refer latest ENT UK guidelines on cancer managementhttps://entuk.org/docs/prof/publications/head_and_neck_cancer• Used key term “classification” on Scott-Browns to search classifications mentioned• Most useful ones included
    • Classifications - Uses• Stage a disease• Make management decisions• Predict outcome - Prognosticate• Monitor progress (treatment and natural)• Compare data
    • Classification of Classifications• Head and Neck Cancer TNM• Otology• Rhinology• Head and Neck Benign conditions (e.g Vascular lesions)• Paediatrics
    • Head and Neck Cancer
    • Squamous Cell Carcinoma
    • Regional NodesLip, oral cavity, oropharynx, hypopharynx, larynx, trachea,paranasal sinuses, major salivary glands, Nx Regional lymph nodes cannot be assessed Nasopharynx Nx nodes cannot be assessed N0 no regional lymph node metastasis N1 Unilateral metastasis in lymph nodes < 6 cm above the supraclavicular fossa N0 No regional lymph node metastasis N2 Bilateral metastasis in lymph nodes < 6 cm above the supraclavicular fossa N3 a Metastasis in a lymph node(s)> 6 cm b extension to the N1 Single ipsilateral lymph node 3-6 cm supraclavicular fossa N2 a Single ipsilateral lymph node 3-6 cm b Multiple ipsilateral nodes < 6 cm c Bilateral lymph nodes < 6 cm N3 Any node > 6 cm Thyroid Nx Regional lymph nodes cannot be assessed N0 No regional U upper neck – above cricoid lymph node metastasis N1 Regional lymph node metastasis a Metastasis in ipsilateral cervical lymph node(s) b Metastasis in bilateral, midline, or contralateral cervical / mediastinal node(s) L lower neck – below cricoid Nx Regional lymph nodes cannot be assessed N0 No regional lymph node metastasis N1 Regional lymph node metastasis a Metastasis in ipsilateral cervical lymph node(s) b Metastasis in bilateral, midline, or contralateral cervical / mediastinal node(s) Nx Regional lymph nodes cannot be assessed N0 No regional lymph node metastasis N1 Regional lymph node metastasis a Metastasis in ipsilateral cervical lymph node(s) b Metastasis in bilateral, midline, or contralateral cervical / mediastinal node(s)
    • Metastasis
    • Stage Grouping
    • Histopathological Grading
    • Definition of T stages• Definitions varies with the site• Refer Latest TNM• https://entuk.org/docs/prof/publications/head_and_neck_cancer
    • Lymph Node Levels
    • Neck Dissections
    • Melanoma ClassificationsBreslow 1 0.75mm 2 0.75 - 1.5mm 3 1.5mm - 4mm 4 >4mmClarks 1 Confined to epidermis 2 Extends to papillary dermis but not to reticulo-papillary junction 3 Extends to reticulo-papillary junction 4 Extends to reticular dermis 5 Extends to subcutaneous tissues
    • Otology
    • Chronic Otitis Media Classification
    • Tos Classification- Pars Flaccida RetractionsGrade 1 - Small attic dimpleGrade 2 - Pars flaccida retracted maximally and draped over neck of malleusGrade 3 - As grade 2 with erosion of outer attic wall (scutum)Grade 4 - Deep retraction with unreachable accumulated keratin
    • Sadé Classification of Pars Tensa RetractionGrade 1 - Slight retraction of TM over the annulusGrade 2 - Severe retraction - TM touches long process of the incusGrade 3 - Atelectasis - TM touches the promontoryGrade 4 - Adhesive otitis - TM adherent to the promontory
    • Tympanograms
    • TympanicumType A: Tumours localised to middle ear cleftType B : Tympano-mastoid tumours no destruction of bone in the infra- labyrinthine compartment of the temporal boneType C : Tumours invading the bone of bone in the infra-labyrinthine compartment of the temporal boneType D : Tumours with intracranial extension
    • Glassock-JacksonGlomus Jugulare TumoursClass I small tumour involving jugular bulb, middle ear and mastoid processClass II tumour extending under internal auditory canal; may extendintracraniallyClass III tumour extending into petrous apex; may extend intracraniallyClass IV tumour extending beyond petrous apex into clivus or infratemporalfossa;may extend intracraniallyGlomus Tympanicum TumoursClass I small mass confined to promontoryClass II tumour completely filling middle ear spaceClass III tumour filling middle ear and extending into mastoid processClass IV tumour filling middle ear, extending into mastoid process or through tympanicmembrane to fill external auditory canal; may also extend anteriorly to internal carotid artery
    • Tympanoplasty TypesType I Reconstruction of TM with intact, mobile ossicular chain (Myringoplasty)Type II Usually absent long process of incus. TM reconstruction and ossiculoplasty with reconstruction of ossiclelever mechanism (ISJ prosthesis)Type III Malleus head and incus absent or removed.i TM reconstructed to lie on stapes head to create columella (Myringostapediopexy)ii Minor colulella: strut from TM/graft to stapes head (PORP)iii Major columella: Stapes crura missing. Strut from TM/graft to footplate (TORP).Type IV only stapes footplate remains. Footplate exteriorised in mastoid cavity, round windowacoustically separated from oval using TM sup margin on promontoryType V fixed stapes footplate, lateral SCC fenestration performed
    • Presbyacusis classification SpeechType Pathology PTA Findings Discrimination Degeneration of the Organ of Corti, Precipitous Good as SpeechSensory Particularly at the drop at High frequencies are Basal Turn of Frequencies spared cochlea. Degeneration of neurones, outer hair PrecipitousNeural cells and inner hair drop at High Very Poor cells and central Frequencies connections Metabolic insult leading toStrial FLAT Good degeneration of stria vascularis GraduallyCochlear Stiffening of the sloping hearing Goodconductive basillar membrane loss
    • House-Brackmann facial nerve palsy grading system Description CharacteristicsI Normal Normal facial function in all areasII Mild dysfunction Slight weakness noticeable on close inspection; may have very slight synkinesis Normal symmetry and tone at rest Forehead: moderate to good function Eye: complete closure with minimum effort Mouth: slight asymmetry III Moderate dysfunctionObvious but not disfiguring difference between two sides; noticeable but not severe synkinesis, contracture, or hemifacial spasmNormal symmetry and tone at restForehead: slight to moderate movementEye: complete closure with effortMouth: slightly weak with maximum effort
