We report the case of a 19-year-old man with neurofibromatosis type 1 who presented for evaluation of odynophagia, left-sided hemiparesis, multiple café au lait spots all over his body, and numerous subcutaneous and cutaneous neurofibromas. Imaging revealed the presence of two large neurofibromas-a 60 x 50 x 35-mm tumor in the left parapharyngeal space and an intradural tumor measuring 25 mm in diameter. We removed the larger tumor via a transoral route with the Harmonic Scalpel. The size of this tumor far exceeded the size of any other reported tumor removed in this manner. Various approaches to the parapharyngeal space have been described in the literature. To the best of our knowledge, this case represents the first report of a transoral removal of a huge parapharyngeal space neurofibroma with a Harmonic Scalpel.
