Masticatory efficiency before and after surgery in oral cancer patients: comparative study of glossectomy, marginal mandibulectomy and segmental mandibulectomy.

This study evaluated the effect of oral cancer surgery on masticatory efficiency. Masticatory efficiency was measured using the ATP absorption method. Eating ability was measured using a questionnaire. Two groups were employed as controls: The "normal occlusion group" consisted of subjects who had a complete set of natural maxillary teeth opposed to mandibular teeth, and the "unilateral occlusion group" consisted of subjects who had lost their molar and premolar teeth on one side of the mandible as a result of caries or periodontal diseases. Three treatment groups, each of 6 patients, were studied: a glossectomy group, a marginal mandibulectomy group and a segmental mandibulectomy group. There were no differences in masticatory efficiency between two control groups. Masticatory efficiencies of the three oral cancer treatment groups were lower than in the unilateral occlusion group, even 12 months after surgery. Masticatory efficiency of the glossectomy group was significantly higher 12 months after surgery compared with pre-surgery. Masticatory and eating abilities of the marginal mandibulectomy group and the segmental mandibulectomy were reduced at 3 and 6 months after surgery. The masticatory efficiency 12 months after surgery was higher in the marginal mandibulectomy group than the segmental mandibulectomy group, although the difference was not statistically significant. The self assessed eating ability 12 months after surgery was significantly higher in the marginal mandibulectomy group than the segmental mandibulectomy group. These results suggest that discontinuation of the mandible may lead patients to eat only foods that do not require a substantial amount of chewing. Hence, the quality of life of patients in the marginal mandibulectomy group was considered to be better than that in the segmental mandibulectomy group.

[Articulatory function in patients receiving glossectomy followed by reconstruction with a recto-abdominal myocutaneous free flap].

Postoperative articulatory functions of patients with tongue cancer have been improved by reconstructive surgery with a radial forearm or recto-abdominal myocutaneous free flap. We examined the postoperative articulatory functions of 10 patients who received reconstruction with a recto-abdominal myocutaneous free flap after glossectomy. The functions were investigated by standardized tests, i. e. a quentionnaires, the 100 Japanese monosyllable speech intelligibility test and a single-word intelligibility test. A confusion matrix was obtained from the results of the monosyllable test. On the basis of resection sites, the present cases were divided into two types: an anterior type and a lateral type. The results are summarized as follows. There was no significant difference in the results of the quentionnareis between the two types. The mean score of the 100 Japanese monosyllable speech intelligibility test in cases of the anterior type was 48% and in those of the lateral type it was 62%. The mean score of the single-word intellibibility test in cases of the anterior type was 75% and in those of the lateral type it was 83%. In cases of the anterior type, dental and alveolar sounds were often confused with fricatives, whereas in the lateral type, velars sounds were often confused with affricates or flaps. These results suggest that our classification based on resection site was useful for investigating postoperative articulatory functions after partial glossectomy.

[Total glossectomy without laryngectomy. Surgical techniques and its controversies].

UNLABELLED: Total glossectomy is the procedure for entire removal of the tongue, practice considered as one of the most mutilating possible done in head and neck surgery. Vital functions altered after tongue resection are: mastication, language and swallowing. It's controversial the role played by total laryngectomy considering the definitive split of respiratory and digestive tracts. Some AA. perform apart both ectomies pending of the suitable rehabilitation. OBJECTIVE: Report of a case of glossectomy recently operated maintaining the larynx and review the several operative steps, the complications until satisfactory swallow was achieved and perusal of literature on this controversial subject.

[Anatomic characteristics of lingual artery and midline glossectomy].

OBJECTIVE: To investigate the relationship between anatomic characteristics of lingual artery and midline glossectomy, for the purpose of increasing operative safety. METHODS: (1) 16 extraoral dissections of the submandibular region were performed on 8 human cadavers and to observe the origin and distribution of lingual artery. (3) The lingual artery was divided into three segments, and the length and adjacent organs were observed and measured. RESULTS: The whole length of lingual artery was (92.88 +/- 13.53) mm; At points of foramen cecum of the tongue, 5 mm and 10 mm prior to foramen cecum, 10 mm behind foramen cecum, and at adjacent part between root of the tongue and epiglotic vallecula, the distances between lingual artery and midline of the tongue were separately measured. The distances were (11.00 +/- 4.95) mm, (8.56 +/- 3.51) mm, (7.78 +/- 3.15) mm, (13.00 +/- 3.28) mm, (15.22 +/- 3.11) mm. The distances between lingual artery and the surface of tongue were (21.4 +/- 5.59) mm, (22.11 +/- 6.74) mm, (22.56 +/- 7.81) mm, (16.56 +/- 5.57) mm, (2.56 +/- 0.73) mm respectively. CONCLUSION: During the midline glossectomy, the lingual artery is easier to be damaged at the position where the root of tongue adjoining epiglottic vallecala. The operation should be done within 10 mm below the surface, 7 mm lateral to the midline, to avoid the damage of lingual artery.

Rehabilitation of a patient with limited oral opening following glossectomy.

Rehabilitation of the glossectomy patient is one of the most difficult and challenging problems for the prosthodontist and speech pathologist. The tongue plays an important role in articulation, control of secretions, formation of a bolus, propulsion of the bolus toward the pharynx, clearing the palate, and initiation of the swallow reflex. This paper presents speech and prosthodontic considerations for a patient who underwent a glossectomy and had the additional problem of reduced oral opening.

[Total glossectomy with laryngectomy].

Because local control of locally advanced cancer of base of tongue and larynx managed with combined chemotherapy and radiotherapy is poor, we proposed total glossectomy with total laryngectomy. Twenty-one patients underwent this operation over a period of 8 years. It was a salvage surgery for 15 patients, and an up-front surgery for the 6 others. Postoperative complications occurred in ten patients, and three patients died in the postoperative period. Mean total duration of hospitalisation was 40 days. Oral feeding could be achieved in 14 patients (mean delay: 46 days), but satisfactory oesophageal voice has never been obtained. We can conclude from the analysis of this series that total glossectomy with total laryngectomy is a heavy surgery, which leads to frequent complications, severe functional sequellae, and poor survival. However, control of pain can be obtained, that justifying this heavy procedure. We recommend that patients and relatives should be fully informed about the consequences of surgery before final decision.

Local recurrence of carcinoma of the tongue after glossectomy: patient prognosis.

We conducted a retrospective review of the prognosis for patients with local recurrence after surgical treatment of carcinoma of the tongue. Glossectomy for squamous cell carcinoma of the tongue was performed in 167 patients. Local recurrence developed in 32 patients including 21 with local recurrence alone, 10 with locoregional recurrence and one with locodistant recurrence. The incidence of local recurrence increased with tumor stage (from 16% of T1 tumors to 46% of T4 carcinomas). Eleven (34%) patients underwent surgical salvage for local recurrence, with only one (9%) patient surviving free of carcinoma at 43 months post-surgical salvage. All of the remaining 21 patients with local recurrence were treated palliatively and all died within one year. Patients who underwent surgical salvage had significantly higher survival rates compared to those treated palliatively. Close follow-up after glossectomy is important for early detection of local recurrence amenable to surgical salvage. However, the overall prognosis for patients with local recurrence was poor, with a three-year actuarial survival rate of only 3%. Therefore, prevention of local recurrence with adequate initial surgical treatment is essential.

Functional restoration after subtotal glossectomy and laryngectomy.

Extensive resection of carcinoma that involves the tongue base and supraglottic larynx is accompanied by significant potential morbidity and mortality. This is often indicated by poor rates of cure and the limited palliation afforded by radiotherapy alone. Removal of a significant portion of the posterior tongue frequently results in intractable aspiration. Techniques in reconstruction of the oropharyngeal defect and tongue base have included primary closure, random flaps, and myocutaneous flaps. Each of these techniques has been successful, to some degree, in resurfacing pharyngeal defects. However, the functional results in regard to deglutition are less than satisfactory as a result of aspiration. Frequently, simultaneous or delayed total laryngectomy is performed to deal with the pulmonary complications. Various types of laryngoplasty do not uniformly correct the problems of aspiration and deglutition associated with subtotal glossectomy. Our experience includes eight patients who had advanced squamous cell carcinoma of the tongue base, vallecula, and the supraglottic larynx. All patients underwent partial or subtotal glossectomy and laryngectomy. The mucosal defect was reconstructed with pectoralis myocutaneous flap. In order to reestablish voice, a primary tracheopharyngeal shunt was created with the use of a portion of cricoid and upper trachea. The majority of these patients have had successful rehabilitation of deglutition, mastication, and speech.

[Evaluation of the handicap by means of the EORTC scale in partial glossectomies].

OBJECTIVES: Different treatments for tongue cancer are more and more efficient but there are heavy functional and aesthetic sequels. The aim of this study was to evaluate the quality of life after partial glossectomy and to adapt the rehabilitation program after surgery. METHODS: Our population of 16 patients (5 females and 11 males), who underwent partial glossectomy, had to quote the auto questionnaire on quality of life (EORTC QOL-C30) and the specific head and neck cancer scale (H&N35). RESULTS: In our population, the patient's satisfaction for the global quality of life was 71%; the functioning scale was 83%, and the mean rate of generic symptoms was 13%. On the contrary, the specific Head & Neck symptom rate was high, with 76% of complains. CONCLUSIONS: The QOL scale could be considered as a good tool for patients to express their difficulties in daily life. It is a reliable and reproducible tool for a follow up study of patients. It allows proposing specific rehabilitation procedures in the post operative period.

Total glossectomy. A technique of reconstruction eliminating laryngectomy.

A series of 15 patients undergoing total glossectomy for advanced carcinoma of the tongue was analyzed with regard to operative management, oral reconstruction, rehabilitation of deglutition and speech, and survival. While patients often underwent elective total laryngectomy to prevent aspiration previously, a method of laryngoplasty has now been devised that permits retention of the larynx with preservation of swallowing and speech. This technique of laryngoplasty may be used for the management of chronic aspiration of any cause.

Recent experience with reconstructive surgery following major glossectomy.

In an attempt to monitor the impact of new reconstructive procedures and shifting interest away from routine preoperative radiotherapy, we have reviewed the 81 patients undergoing major glossectomy and reconstruction (MGR) at the Royal Marsden Hospital, London and Surrey, England, between 1975 and 1987. While there were four marginal and 13 major reconstructive failures, 11 of the latter were successfully managed with an alternative flap, thus providing a prompt and effective palliation for most of these patients. An evolution in our choice of reconstructive procedures as well as a recent trend toward using MGR as a primary therapeutic modality were noted. Data relating to speech following reconstruction and diet rehabilitation were encouraging, particularly with the use of the latissimus dorsi flap. Survival following MGR, however, was dismal due to early local and regional recurrence.

Total glossectomy with laryngeal preservation.

OBJECTIVE: To evaluate the results of a planned combined therapy with surgery and postoperative radiotherapy in the management of large (T3 to T4) squamous cell carcinomas of the tongue-tongue base in properly selected patients. PATIENTS AND METHODS: Twenty-one patients underwent this procedure in a 4-year period. The selection criteria were directed to identify those patients in whom laryngeal preservation was feasible and who were motivated. Five categories of patients were included: those with (1) large primary tumors of the tongue-tongue base; (2) recurrence after initial radiotherapy, brachytherapy, chemotherapy, or a combination of these modalities; (3) recurrence after initial surgery and radiotherapy; (4) double primary tumors; and (5) second or third primary tumors arising in the tongue or base of the tongue. Preoperative investigation included examination under anesthetic and magnetic resonance imaging. Depending on the proximity of the primary tumor to the mandible, a mandibular split, a marginal resection, or a segmental resection was carried out. Soft-tissue replacement was achieved by a myocutaneous or a muscle flap of the pectoralis muscle with split skin. Whenever possible tissues of the contralateral floor of the mouth were also used. Laryngeal suspension was performed in all cases. Postoperative radiotherapy consisted of megavolt therapy, 66 Gy in 6 weeks to the primary site and both sides of the neck. RESULTS: Resumption of swallowing and speech was achieved in all patients. External deformity was slight. Patients were able to return to their families. CONCLUSIONS: Total glossectomy with laryngeal preservation in properly selected patients provides local and regional control and preserves quality of life.

A systematic approach to functional reconstruction of the oral cavity following partial and total glossectomy.

Mobility, sensation, volume, and to a lesser extent, the shape of the tongue following partial glossectomy are critical elements to the successful rehabilitation of the patient with oral cancer. Our approach to tongue reconstruction is based on the extent and functional status of the residual tongue and whether there is an associated mandibulectomy. Despite the devastating effects of ablative surgery and radiation, the application of available reconstructive techniques can help to improve the quality of life of these patients. Herein, we present a revised classification scheme for tongue defects along with a discussion of the optimal method for reconstruction based on available techniques.

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.

Prosthodontic and speech rehabilitation after partial and complete glossectomy.

A multidisciplinary approach to the rehabilitation of four glossectomy patients has been presented. Points emphasized were the anatomic defects, their effect on the three oral functions of mastication, deglutition, and speech, and the various prosthetic modifications found most effective to restore the impaired oral functions.

A functional speech impression used to fabricate a maxillary speech prosthesis for a partial glossectomy patient.

Surgery for cancer of the floor of the mouth often results in alteration of the muscles of the tongue and floor of the mouth. Both primary and secondary surgical procedures often result in scar formation with reduced mobility of the tongue during speech and deglutition. Speech is often used as a diagnostic tool in the placement of the anterior teeth during fabrication of a prosthesis. Speech can similarly be used to help determine the proper placement of a speech portion of the prosthesis. The prosthetic rehabilitation approach described lowers the palatal vault with a false palate to enable the tongue to function against it during speech (Fig. 15). Group studies have shown that the design and fabrication of speech prostheses for partial glossectomy patients have significantly improved speech and swallowing for these patients. A speech pathologist is helpful during diagnosis, and speech therapy is necessary for significant speech improvement. Prosthetic rehabilitation alone cannot be expected to improve speech.

An interim prosthesis for the glossectomy patient.

The use of a simple patient-held prosthesis for improving speech in a patient with mandible and tongue resections has been described. As subjectively perceived and objectively verified, speech intelligibility improved in a test patient. There were no apparent risks or lengthy therapy. The ease of fabrication and low cost indicate that this prosthesis may be of value in aiding the speech of glossectomy patients.

Effect of a maxillary glossectomy prosthesis on articulation and swallowing.

Swallowing was found to be substantially improved with the prosthesis. Less aspiration, less time necessary to complete the swallow, and greater variation in food consistency tolerated were all positive results of the prosthesis. In addition, videofluoroscopic studies of tongue movements during speech revealed that tip-alveolar /t-d/ and back-velar /k-g/ productions were more normal with the prosthesis. With the prosthesis, the understandibility of /t/ and /d/ was improved 20% and that of /k/ and /g/, 33%. It is clear that compromises must be effected in prosthesis design to facilitate improvement in both speech and swallowing. A large prosthetic mass in the oral cavity can also negatively change speech resonance. These issues are being investigated, as are acoustic and perceptual studies of speech articulation. Future research should address whether a combination of maxillary and mandibular prostheses would result in better speech and swallowing function. A mandibular prosthesis could replace missing teeth and alveolar contour that might influence speech and swallowing. A mandibular prosthesis might also allow construction of a smaller maxillary glossectomy prosthesis to interact with the mandibular prosthesis.
