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.
