Removal of this lesion may unmask the SMCP with consequent worsening of speech nasality. Nasal septal polyp protruding to the nasopharynx in a patient with SMCP has not been reported before in the literature. This report describes a septa! polyp arising from the posterior border of the nasal septum and protruding in the nasopharynx in a 16-year-old girl with submucous cleft palate. The polyp appeared to support the weak palate, and they acted as a ball and socket during speech articulation. Removal of this polyp may result in velopharyngeal insufficiency. Trans-nasal endoscopic removal of the polyp with obturation of the velopharyngeal port with a superiorly-based pharyngeal flap was performed in the same sitting. Pre- and postoperative speech evaluation using auditory perceptual assessment and nasometry revealed no worsening of nasality, also the patient reported improvement of her nasal breathing. We concluded that, the presence of a nasopharyngeal polyp in a patient with SMCP may compensate the speech problem. Removal of the polyp and treatment of SMCP by a pharyngeal flap in one-sitting is an effective procedure without adverse effect on patient's speechen-USnasal septal polypnasopharyngeal polypsubmucous cleft palatehypernasalitypharyngeal flapArticlehttps://doi.org/10.7759/cureus.14787
