The study objective – to evaluate the feasibility of correcting eating disorders in patients undergoing surgery for oral and oropharyngeal cancers using various reconstructive techniques to restore postoperative defects.Materials and methods. Between 2012 and 2019, a total of 56 patients with stage II–IV oral and oropharyngeal cancer underwent reconstructive surgery after either hemiglossectomy or glossectomy. The patients ranged in age from 26 to 70 years. The patients were divided into two groups. Group I consisted of 36 (64.3 %) patients who underwent tongue reconstruction using rotation flaps. For reconstruction of hemiglossectomy defects, a chin flap was used, and for reconstruction of glossectomy defects, a pectoral flap was used. Group II comprised 20 (35.7 %) patients who underwent tongue reconstruction using free revascularized flaps. For the tongue reconstruction after hemiglossectomy, the radial flap, medial sural perforator flap and fasciocutaneous anterolateral thigh flap were used. For the tongue reconstruction after glossectomy, the fasciocutaneous anterolateral thigh flap was used. The acts of chewing and swallowing were restored during speech rehabilitation due to the activation and coordination of the work of the muscles of the cheeks, lips, soft palate, pharynx, and the reconstructed tongue. Eating disorders were assessed by interviewing patients. A comparative analysis of eating disorders included mobility and coordination of facial muscles and reconstructed tongue, increased sensitive in the oral cavity, the presence of aspiration and nasal regurgitation, and subjective difficulties of patients. The time before the start of rehabilitation and its duration were taken into account. Patients were interviewed before the start of the combined treatment, at the beginning and after the completion of rehabilitation.Results. After the completion of rehabilitation, all patients received food by the oral route. The best outcomes were achieved in group 2a patients, who underwent tongue reconstruction with free revascularized flaps. This group of patients had a lower percentage of the asymmetry of facial muscles and limited mobility of the tongue compared to other groups of patients.In the subgroups of patients undergoing glosssectomy, most of the studied parameters did not have statistically significant differences in values. However, it should be noted that in group 2b, the period from the date of surgical treatment to the beginning of rehabilitation was significantly longer than in group 1b.Conclusion. The use of the microvascular surgical techniques using various donor flaps creates the basis for a more complete functional recovery and expands the rehabilitation potential of patients after surgical treatment of oral and oropharyngeal cancer.
The research Institute of Oncology of the Tomsk Research Center for Voice Rehabilitation of patients with cancer of the larynx and laryngopharynx after laryngectomy has developed a method for restoring voice function Ьу forming an esophageal voice using the method of biofeedback. The method of biofeedback speeds up the formation of voice skills due to the fact that the patient gets the opportunity during voice training consciously manage such parameters of the voice being formed as the duration of phonation, pitch frequency, frequency stability of the pitch. In order to study the effectiveness of the method developed by us, a study was conducted of the results of voice rehabilitation of 80 patients with cancer of the larynx and hypopharynx. Voice function was restored in 71 (88.75%) patients in the period from 8 to 22 days.
Currently accepted standard of surgical treatment of patients with locally advanced stage III and IV laryngeal and laryngopharyngeal cancer is laryngectomy which leads to loss of vocal function. Therefore, vocal rehabilitation is one of the most important tasks of the doctor. It allows to increase quality of life of patients after treatment. Currently used techniques of vocal rehabilitation have their advantages and disadvantages. The article considers various techniques of vocal rehabilitation, primarily, subtotal laryngectomy with laryngotracheal shunt as a promising method of surgical rehabilitation of patients with locally advanced caner of the larynx and laryngopharynx.
