Metastatic disease of the temporal bone.

This paper discusses metastatic disease of the temporal bone, and illustrates its discussion with a case history. The incidence, signs, symptoms, and treatment generally recorded are discussed. The histopathology of such lesions, as well as a documentation of those organ systems most likely to provide temporal bone metastatic spread, is noted. As the primary neoplasias of the temporal bone, metastatic disease may coexist with or mimic chronic otitis media. It is the wary surgeon who carefully analyzed his patient, the history, the intensity of recognizing neoplasia with or without associated chronic otitis media.

Clinical interpretations of transient otoacoustic emissions.

PURPOSE: The purpose of this study was to characterize the relation of different ordinal patterns of transient otoacoustic emissions (TEOAES) with respect to underlying otologic disorders and auditory status. PATIENTS AND METHODS: The results of TEOAEs in 225 patients with various auditory disorders were investigated and compared with normative data established from 90 subjects of various ages. TEOAEs were categorized according to four patterns: (1) normal (general response level within 90% of normative data, (2) reduced amplitude (general response level was > or =2 dB peak sound pressure level (pSPL), but less than the mean -1.64 SD of the normative data), (3) abnormal morphology of frequency spectrum (general response level was within normal limits, but reduced at > or =2 individual octave frequencies between 1,000 and 5,000 Hz), and (4) total absence (response level <2 dB pSPL). RESULTS: This study showed that the normal pattern of TEOAEs, in terms of response amplitude, varied with age. Our results further indicated that a reduced amplitude pattern of TEOAEs was noted in patients with a mild sensorineural hearing loss (SNHL), negative tympanometric pressure, a pressure-equalization tube, and Meniere's disease. TEOAEs provided good frequency-specific information for patients with a noise-induced hearing loss. All patients with ossicular chain abnormalities, more than moderate SNHL, and a middle ear mass or effusion had total absence of TEOAEs. Patients with acoustic neuroma and brainstem lesions presented a complex profile of TEOAEs. In the follow-up of auditory function in patients undergoing otologic surgery, different patterns of TEOAEs between the preoperative and postoperative recordings were evident, which correlated with the hearing thresholds and middle ear status. The abnormal findings of TEOAEs due to specific auditory diseases were discussed. CONCLUSION: The interpretation of TEOAEs can be facilitated through an analysis of specific patterns and in combination with other audiologic tests.

Radical combined treatment of locally extensive head and neck cancer in the elderly.

PURPOSE: Few studies have described the effects of aggressive combined therapy for locally extensive head and neck cancer in the elderly. Our study evaluated the outcome of this particular cohort of patients after such treatments. METHODS: Survival, failure, morbidity, and complication rates were determined retrospectively in 43 elderly patients with stage III or IV head and neck cancer who underwent curative surgery and postoperative radiotherapy (n = 33) or neoadjuvant, 3-drug chemotherapy plus radiotherapy (n = 10) between the years 1977 and 1992. RESULTS: The crude survival rate at 3 years was 27% in patients managed by surgery plus radiotherapy, and 30% in individuals treated with chemoradiation; the corresponding locoregional failure rates were 23% and 30%; and the distant failure rates were 13% and 0%, respectively. The acute toxicity rate was 12% in the surgery plus radiotherapy group and 30% in the chemoradiation patients; the corresponding late complication rates were 0% and 10%. There were no toxic deaths. CONCLUSION: Radical combined treatments can be performed safely and achieve long-term, disease-free survival in selected elderly patients with locally extensive head and neck cancer.

Laryngotracheoesophageal cleft: the anterior approach.

Laryngotracheoesophageal cleft was reported by Richter in 1792 after he examined an infant at autopsy and found a common lumen of esophagus and laryngotrachea. The next case was not noted until 1949 by Finlay. A recent review shows 40 cases in the world literature to date. Successful surgical approaches to some of these problems have basically employed a lateral pharyngotomy technique. In the case presented herein, the exact pathology was obscured by a severe tetralogy of Fallot and recurrent pneumonitis from a suspected high H-type tracheoesophageal fistula. The length of this cleft prompted an anterior approach with laryngo-fissure, cricoidotomy, and division of four tracheal rings for a complete and successful repair. Thorough endoscopy of all infants suspected of any laryngeal anomaly would yield an earlier diagnosis and opportunity for reconstruction of the cleft.

Lentigo maligna melanoma.

Lentigo maligna melanoma is a malignant melanoma with a recognizable clinical pattern. It is a slow-growing, pigmented tumor evolving from a premalignant lesion on the exposed cutaneous surface of an elderly patient. Histologically, it is marked by pleomorphism of melanocytes with evidence of invasion. A case is presented demonstrating the features of this malignant melanoma with an exceptionally good prognosis. The importance of the clinical and histologic correlation of emphasized to ensure proper diagnosis and treatment.

Synovial cell sarcoma.

Synovial sarcoma of the head and neck is a rare lesion. Based on previous literature reports, these lesions carry a poor prognosis. Case reports of two patients diagnosed and treated recently for head and neck lesions of this type are presented. A review of pathologic sections at the Armed Forces Institute of Pathology (AFIP) suggests that this lesion is more colmon than believed previously.

Cartilage regeneration: a clinical and experimental study.

Regeneration of the alar cartilage has been observed in patients undergoing revision rhinoplasty. Material preserved from the first procedure was compared to that removed at the secondary procedure. Microscopic findings confirm the cartilage regrowth. An experimental study was undertaken to determine if cartilage regeneration could be reproduced in animals. White New Zealand rabbits were utilized in the study. Gross and microscopic findings indicate that cartilage does regenerate if the perichondrium is not removed.
