The following should be noted on endoscopic examination:

• Location and extent of tumour involvement. This is particularly important for assessment of

posterior extent of tumour in the posterior tongue and oropharynx

• Laryngeal function including vocal cord mobility and supraglottic sensation

• Presence and location of synchronous lesions along the upper aerodigestive tract secondary to

field cancerisation

• Biopsy of tumour and any suspicious lesions for histological diagnosis
