Introduction:
Patients who undergo oncological surgery due to midface neoplasms require postoperative team care in order to restore the proper functions of chewing, swallowing and speech. The damage to the natural barrier between the oral and nasal cavities causes the passage of air between these spaces leading to deterioration in articulation and speech understanding. The aim of prosthetic treatment is to restore the continuity of the missing structures through denture with an obturator. Its tightness improves speech and swallowing, and thus increases the quality of life. Complementing the prosthetic treatment with speech therapy care provides patients with easier adaptation to new articulation conditions.

Aim of the study:
To evaluate the speech in a patient who underwent partial resection of the upper jaw and was fitted with a complete denture with an obturator.

Methods:
Speech assessment was performed by a speech therapist on the basis of the Speech Disorders Diagnostic Questionnaire with particular emphasis on aphasia and dysarthria. The study was conducted before and after prosthetic treatment.

Case report:
The paper presents a clinical case of a patient a few years after maxillary resection in the anterior region. In addition, the patient was edentate in the maxilla and the mandible. The patient was fitted with an upper late post-resection denture with an obturator and a complete lower denture.

Conclusions:
The use of a denture with an obturator significantly improved the quality of the patient’s speech. In this patient the speech pathology was defined as postoperative oncogenic dyslalia. The patient was recommended speech therapy.
