Complications in the treatment of facial fractures.

The evaluation and treatment of the more common and severe complications of facial fractures are reviewed. This analysis includes such conditions as nonunion and malunion of the maxilla, mandible, and zygoma, temporomandibular ankylosis, diplopia, enophthalmos, hypertelorism, dacrocystitis, and cerebrospinal otorhinorrhea. The discussion attempts to stress the importance of diagnosis regarding cosmesis and functional abnormalities. When possible, the pathophysiology is elucidated and evaluated to decide about methods of prevention. Preferred traditional and improved techniques of management are noted and compared to some of the less satisfactory procedures.

Tongue mobility in speech after partial glossectomy.

Recovery of tongue mobility in speech was investigated in 5 partial glossectomy patients. Jaw range of motion used in speech, and tongue contour changes relative to the jaw, were assessed using sequential videofluoroscopic data recorded presurgery, postsurgery, and postradiotherapy. Data from 2 normal controls were included for comparison. Tongue mobility relative to the jaw was found to be restricted postsurgery. Approximately 4 months later, following radiotherapy, tongue mobility increased. Range of jaw motion used in speech was unchanged. Results are interpreted as preliminary evidence that in this small group of cancer patients, radiotherapy following surgery did not prevent continued recovery of tongue function for speech in the early postradiation period.

Objective assessment of swallowing function in head and neck cancer patients.

Swallowing function was evaluated with scintigraphy in 37 patients with head and neck cancer. The patients were examined before and during the course of either surgery, chemotherapy, and/or radiotherapy. A total of 118 scintigraphic studies were performed. Scintigraphic results of bolus flow and aspiration were correlated with clinical findings. Both scintigraphic and clinical studies indicated a worsened swallowing function in 12 patients. These same studies indicated improvement of swallowing in another 13 patients. In 11 patients, both studies revealed either no apparent change or mixed changes in swallowing function after the course of therapy. In only 1 patient was there disagreement between the scintigraphic and clinical assessment of swallowing function. It is our opinion that scintigraphy is a useful method for objective assessment of swallowing function during and after the course of treatment of head and neck cancer patients.

Swallowing of bolus types by postsurgical head and neck cancer patients.

BACKGROUND: Clinically, head and neck cancer patients with anterior resections have better postoperative outcomes than do patients with posterior resections. METHODS: Videofluoroscopy was used to study the swallowing characteristics in postsurgery head and neck cancer patients and normal controls. Most patients received post-operative radiotherapy and chemotherapy, and no cancer recurrence was noted at the time of study, 4-8 months posttreatment. Bolus types included: 3 mL and 10 mL liquid barium, barium paste, and barium-coated cookie. Temporal measurements and a count of the number of swallows required to ingest each material were made from the videotaped data. Statistical analysis using an unbalanced univariate repeated measures ANOVA was performed. RESULTS: The major differences were found between bolus types, with few differences noted between surgical groups (anterior vs posterior resections) and normal controls. Patients took longer to ingest viscous material, accomplishing this by multiple piecemeal and clearing swallows. Coordination of mastication and swallowing of the cookie was different between normal and patient groups. CONCLUSIONS: Patients who are able to swallow reasonably well postoperatively maintain normal coordination and timing of swallowing activity and do not vary these parameters to compensate for structural inadequacy. Instead, repeated swallows are used.

Temporal artery-based forehead flap.

The historical development of the forehead flap is reviewed, and an operative experience using delayed and nondelayed techniques in 30 cases is described. The reliability of the forehead flap is evaluated with regard to patient morbidity and correction of deformity and dysfunction in such sites as the cheek, lip, corner of the mouth, floor of the mouth, tongue, pharyngeal wall, and tonsil. Analyses include length of hospital stay and complications, as well as the relationship of these factors to the methods employed in the reconstructive processes. The advantages and disadvantages of the various techniques are illustrated using individual cases.
