13-cis-Retinoic acid has been reported to be effective in treating oral leukoplakia. We randomly assigned 44 patients with this disease to receive 13-cis-retinoic acid (24 patients) or placebo (20), 1 to 2 mg per kilogram of body weight per day for three months, and followed them for six months. There were major decreases in the size of the lesions in 67 percent (16 patients) of those given the drug and in 10 percent (2 patients) of those given placebo (P = 0.0002); dysplasia was reversed in 54 percent (13 patients) of the drug group and in 10 percent (2 patients) of the placebo group (P = 0.01). The clinical response to the drug correlated with the histologic response in 56 percent (9 of 16) of the patients evaluated. Relapse occurred in 9 of 16 patients two to three months after treatment ended. The toxic effects of the drug were acceptable in all but two patients. Cheilitis, facial erythema, and dryness and peeling of the skin were common; conjunctivitis and hypertriglyceridemia also occurred. All adverse reactions could be reversed by reducing the dose or temporarily discontinuing the drug. We conclude that 13-cis-retinoic acid, even in short-term use, appears to be an effective treatment for oral leukoplakia and has an acceptable level of toxicity.

A study was undertaken to explore the relationship between depression and tumor invasiveness in a group of 45 patients with cancer of the head and neck at different stages. Patients were assessed for depression at the time of their first visit to a tertiary care cancer center, before definitive diagnosis was made and treatment initiated. Depression was assessed by using the DSM-111 derived dysthymia scale of the Millon Clinical Multiaxial Inventory and by clinical interview which elicited symptoms of major depression. We hypothesized that if depression were related to the physical effects of the tumor then patients with more advanced cancer would be more depressed due to associated pain, discomfort and nutritional deficits. Contrary to expectations, results showed that depression scores were distributed equally throughout all stages. However, stage x gender analysis showed a significant effect with females having early stage (1 and 2) cancer being most depressed. Physical symptoms and nutritional factors were not associated with depressed affect but marital status (unmarried) and stress scores were. The high frequency of depression reported in head and neck cancer patients is not necessarily the result of the malignant process or a response to treatment but may be related to premorbid factors of which social support is one variable.

Reconstruction of soft tissue defects after temporal bone resection can vary from simple closure of the external auditory canal to complex flap coverage of extensive defects. Between 1987 and 1996, 34 patients underwent lateral skull base resections and reconstruction for invasive carcinoma of the temporal bone. Seven underwent sleeve resection and/or radical mastoidectomy. Sleeve resection was managed with tympanoplasty, canalplasty, or obliteration of the external auditory canal (10). There were 24 lateral temporal bone resections and four subtotal temporal bone resections. Larger defects created by lateral and subtotal temporal bone resections required closure with a combination of temporalis flaps and local rotational cutaneous flaps (13). Lower island trapezius flaps (five), free flaps (four), and pectoralis major flaps (two) were also used. Indications and efficacy of each method are discussed, and treatment outcomes are presented.

Infections of the deep spaces of the head and neck may still result in major consequences despite the advent of antibiotics. Abscesses in these areas merit special consideration by today's head and neck surgeon because of their relative rarity and the life‐threatening complications that may follow inadequate treatment. Diagnosis and management decisions are enhanced by use of computerized tomography (CT) as an adjunctive study. The EMI scan may demonstrate either cellulitis of the neck requiring no surgery or a space abscess displacing the adjacent structures thus requiring surgical drainage. Anatomy of the significant fascial planes and spaces of the neck will be reviewed employing CT utilizing 3 mm cuts. Specific case presentations feature early diagnosis and management.
