Emergency parotidectomy for expansile cavernous hemangioma.

A rare case of emergency parotidectomy in a boy of 12, necessitated by a sudden, rapid and marked increase in size of a parotid hemangioma is describe. The literature dealing with parotid hemangiomas in adults is reviewed; the number of cases reported is small. The histological differences and the natural history of parotid hemangioma in adults and in infants are described. The therapeutic approach is discussed.

Surgical correction of lateralized eardrum.

The complication of retraction and lateralization of the graft after a tympanoplasty operation is described, and the underlying mechanism discussed. This complication occurs mainly when using the overlay procedure and causes a severe conductive hearing loss. A surgical technique for correcting this problem is described. It consists of removing all of the former graft, positioning the new graft medial to the eardrum remnants and covering the denuded ear canal bone with split-thickness skin graft. The results of 7 cases successfully treated by the technique described are presented.

Characteristics of tinnitus in acoustic trauma.

Several parameters of tinnitus were investigated in a group fo 102 subjects suffering from acoustic trauma. These parameters were then compared to the results of the hearing tests and subjective complaints. The frequency and intensity of tinnitus were established by the usual matching technique with a clinical audiometer. The most effective masking of the tinnitus due to acoustic trauma was by pure tones. There seems to be a correlation between the tinnitus level and the hearing loss level at the frequency at which the hearing loss was most severe. A significant association was found between the matched tinnitus level and its description by the patient. There is also an association between the severity of the acoustic trauma and the perceived loudness of the tinnitus, as well as other subjective complaints.

Treatment of malignant external otitis in its initial stage.

A method of treating malignant external otitis in its initial stage is described. The treatment is based on repeated curettage with Epontol under light general anesthesia. This method requires no systemic antibiotic treatment, can be carried out as an office procedure, and effects a complete cure in a relatively short time.

Effectiveness of prophylactic antibiotic treatment in mastoid surgery.

This article describes a prospective study of the effectiveness of prophylactic antibiotic treatment in preventing infection following mastoid surgery. Seventy-two patients who underwent surgery for chronic middle ear disease served as the basis for this study. Bacteriologic findings from middle ear discharge, showing aerobic and anaerobic bacteria, are reported. The patients were randomly classified into two groups, one undergoing surgery with preventive antibiotic treatment with clindamycin and gentamycin and the other undergoing surgery without antibiotic therapy. The early postoperative inflammatory complications are presented. No significant differences were found in the incidence of these complications between the two groups. In view of the results, the effectiveness of preventive antibiotic treatment in mastoid surgery is questioned.

Ear injury caused by elevated intratympanic pressure during general anaesthesia.

Two cases of middle-ear injury, due to sharp fluctuations of intratympanic pressure as a result of general anaesthesia with nitrous oxide are presented. A study is reported indicating that the degree of these fluctuations is a function of the concentration of nitrous oxide. In order to reduce the risk of middle-ear injury due to nitrous oxide anaesthesia, it is suggested that the lowest concentration feasible should be used where there is a history of previous ear surgery.

Surgical reduction of the broad nose.

The successful surgical reduction of the broad nose encompasses special surgical techniques involving three nasal structures: the nasal bones, the nasal tip, and the nares. Surgical techniques for reduction of the broad nose are presented that produce a satisfactory esthetic result.

Benign course of juvenile laryngeal papillomata.

A 17 month-old child with laryngeal papillomata is presented. The symptoms were stridor and gradually developing dyspnea. He underwent two surgical procedures within 4 months, using microsurgical techniques, and eventually recovered. The etiological factors of this rare entity are discussed. The relatively benign course in our patient is stressed, in view of the usual protracted course which is reflected in the literature.
