In the majority of patients, FBS develops post-operatively. However, in rare instances it may present in a preoperative setting. <strong>Case description: </strong>Two cases of FBS developing preoperatively secondary to parotid gland tumour are presented.&nbsp; The patients, 54 and 30 years old, presented with complaints of electric-shock like pain localized over the periauricular region. In each case the pain was triggered following first bite of the meal. In both cases, pain lasted for a few seconds and with subsequent bites subsided only to return at the beginning of next meal. <strong>Practical implications: </strong>Preoperative occurrence of FBS in the absence of a history of trauma or surgery should necessitate a thorough investigation and follow up for an underlying salivary gland tumour.</p&gt;}, number={1}, journal={Journal of Cancer & Allied Specialties}, author={Nasir, Khawaja Shehryar and Hussain, Raza and Jamshed, Arif}, year={2019}, month={Dec.} }
