Palatal island flap for reconstruction of oral defects.

This communication describes the technique of the palatal island flap and its usefulness in intraoral reconstruction, with a modification for increasing its extension by means of the palatine foramen free-up procedure. The other modalities, with their attendent advantages and disadvantages for intra-oral reconstruction, are briefly reviewed.

Prevalence of Epstein-Barr virus in oral squamous cell carcinoma.

Forty-six samples of oral squamous cell carcinoma (OSCC) were evaluated for the prevalence of Epstein-Barr virus (EBV) infection by the polymerase chain reaction (PCR), Southern blot hybridization, and in situ hybridization (ISH). EBV DNA was detected in 7 (15.2 per cent) out of 46 samples by a combination of PCR and Southern blot hybridization methods. All seven positive samples showed well-differentiated carcinoma, thus suggesting a possible relationship between EBV infection and the degree of differentiation of carcinoma tissue. Latent infection membrane protein 1 (LMP1) was detected immunohistochemically in six of the EBV-positive OSCCs. However, no signal of the EBV-encoded small RNA (EBER)-1 was demonstrated by the ISH method. No significant relationship was observed between EBV infection and lymph node metastasis. A follow-up study (range from 4.4 to 79 months; mean 34.9 months) showed no recurrence or death to occur in the EBV-positive patients, which thus suggested a good prognosis for EBV-positive OSCC patients.

Functional outcome in soft palate reconstruction using a radial forearm free flap in conjunction with a superiorly based pharyngeal flap.

BACKGROUND: Speech and swallowing problems due to velopharyngeal incompetence may follow soft palate resection and reconstruction. Over the past 3 years, we have developed the use of a superiorly based pharyngeal flap in conjunction with a radial forearm flap for soft palate reconstruction. METHODS: This paper describes the technique in detail and compares the functional results in a study with patients undergoing soft palate resection for squamous cell carcinoma treated with or without a pharyngeal flap as an adjunct to a radial forearm free flap for soft palate reconstruction. Seven patients had one quarter or one half soft palate defects reconstructed with a radial forearm flap alone. Of the 11 patients undergoing three quarter or total soft palate resections, all were reconstructed with a radial forearm flap, but 5 were treated with an additional superiorly based pharyngeal flap. The functional outcome for all the patients was analyzed and compared. RESULTS: Our results show that the addition of the superiorly based pharyngeal to the radical forearm flap in soft palate reconstruction results in improved speech and swallowing. We recommend the use of the additional flap in resections in which more than one quarter of the soft palate is included.

STNMP: a new system for the clinico-pathological classification and identification of intra-oral carcinomata.

A new system for the notation of intra-oral carcinomata has been described. It differs from all previous TNM classifications in that both the site (S) and the pathology (P) have been taken into consideration in addition to the conventional tumour (T), node (N) and metastasis (M) generally used. Both of these additional features have been recognized as important factors in assessing the prognosis of the patient. This new system additionally functions as a means of disseminating the maximum of clinical information succinctly and in a readily communicable format. A further innovation has been the introduction of a means of quantitatively assessing the significance of particular clinical and pathological features and from these values predicting the prognosis. For comparative purposes we have defined four stages corresponding with the stages used in the conventional TNM classification. We have applied the STNMP classification to a random sample of 136 cases of intra-oral carcinomata with more than 5 years follow-up. Particularly in defining those patients with a good prognosis, i.e. 5 year plus survival, this system has proved to be considerably more accurate than the existing staging methods. We propose that for a trial period this system should be widely used in parallel with the conventional TNM classification and staging in order to evaluate its true worth in the clinical situation. With further use it will probably be necessary to adjust the numerical weighting given to particular features, but this can only be accurately assessed when a very large number of patients has been evaluated. Our figures support the clinical impression that patients with poorly differentiated squamous cell carcinomata have a shorter survival than those with well differentiated lesions and that the degree of differentiation of the tumour is directly proportional to the survival of the patient. When considering the site of the tumour we have based our grading on the known survival curves for squamous cell carcinomata at different sites.

Persistent carcinoma of the oropharynx and oral cavity re-treated by after-loading interstitial 192Ir implant.

After-loading implantation techniques apparently offer an effective alternative in the management of persistent (or recurrent) oropharynx and oral cavity carcinoma postirradiation. A total of 29 patients with such lesions was treated from February 1974, to July 1975, in the LAC/USC Radiation Medicine Section, using after-loading 192Ir implantation techniques. These patients all had extensive persistent cancer after "full tolerance" irradiation (with or without previous surgery) and were referred for palliation or for possible salvage. Additional doses administered ranged from 5000 to 7000 rads in three to five days. Eighteen of the 29 patients (63%) have had complete local control for 18 to 36 months. These patients have maintained a relatively satisfactory palliative status. Ten of the 29 are dead. Follow-up periods are short, but early indications are that problem patients with persistent cancer after "full tolerance irradiation" can be salvaged, or at least satisfactorily palliated, with after-loading interstitial implant techniques. Clinical details, sites of involvement, implantation techniques, dosimetry methodology, reactions and complications will be described.

Treatment-related esophageal stricture in pediatric patients with cancer.

BACKGROUND: Intensive antineoplastic regimens have enhanced long-term survival in pediatric patients with cancer, but can result in long-term complications. Esophageal stricture formation is one such complication. METHODS: We reviewed the experience with benign esophageal stricture in pediatric patients with cancer over the past 15 years in a major cancer center. Clinical course, along with endoscopic, radiologic, and manometric esophageal studies, was reviewed. RESULTS: Esophageal strictures formed in five pediatric patients who were treated with radiation and/or chemotherapy. Stricture formation was associated with abnormal esophageal motility in four out of the five patients. Repeated esophageal dilation was performed from 3-50 times and resulted in stricture resolution in only 2 of the 5 patients. CONCLUSIONS: Esophageal stricture formation in this population is rare, but is associated with long-term morbidity.

Primary neck management among patients with cancer of the oral cavity without clinical nodal metastases: A decision and sensitivity analysis.

BACKGROUND: A standardized neck management strategy for oral cancer patients without clinical nodal metastases remains to be established. Consequently, a decision and sensitivity analysis of two neck management protocols, involving either prophylactic neck dissection or careful observation, was conducted using the Oral Cancer Registry of Kyushu, Japan. METHODS: We calculated probabilities of subclinical nodal metastases and 5-year survival using the registry data. A two-way sensitive analysis was conducted using the probabilities and parameters of the complete nodal metastasis resection rate (x) and a utility rating that describes the health state induced by dissection (y) compared with the neck condition in a careful-observation group. RESULTS: We solved the threshold curve for y and x for the expected utility between the two groups. The results showed that prophylactic neck dissection must guarantee a complete resection of subclinical nodal metastases with no disadvantage to health state to be evaluated as equally satisfactory as careful observation. CONCLUSIONS: Careful observation involving standardized systematic preoperative and postoperative screening of the neck seems preferable to prophylactic neck dissection for oral cancer patients without subclinical nodal metastases.

Reconstruction of the hard palate using the radial forearm free flap: indications and outcomes.

BACKGROUND: Although prosthetic obturation is the "gold standard" for restoration of hard-palate defects, obturators can be problematic. We present 10 cases of palatal reconstruction with the radial forearm free flap and compare patient satisfaction with defect-matched patients rehabilitated with prosthetic obturation. METHODS: Twelve patients who underwent radial forearm free flap (RFFF) reconstruction of a hard-palate defect and eight patients, with similar-sized defects who were rehabilitated with a prosthetic obturator, were evaluated for donor site and recipient site complications, diet, and patient satisfaction. RESULTS: All the patients in both groups were able to resume an unrestricted diet with normal mastication and articulation. Both groups achieved equivalent satisfaction scores with regard to appearance, chewing, and taste; however, the patients reconstructed with an RFFF reported higher satisfaction scores in speech, comfort, convenience, and social interaction. CONCLUSIONS: RFFF reconstruction of hard-palate defects provides a functional alternative to conventional prosthetic obturators.
