Encountering a nasopharyngeal polyp in a patient with submucous cleft palate (SMCP) is a difficult problem, as the lesion could support the weak palate. 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 septal 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 speech.
