Masseter and temporalis muscle transpositions may be considered in cases of longstanding facial paralysis and in the congenital absence of the facial nerve or muscles. The basic advantage of this technique is the introduction of a large volume of living and dynamic muscle into the face. Additional advantages include simplicity, the support provided, enhancement of the possibility of myoneurotization, and no loss of other significant function. In many instances, facial movement improves for a period of approximately two years, and the long-range effect would suggest some degree of rehabilitation of the facial muscles. Our combined experience with over 100 muscle transpositions indicates the efficacy and success of this technique in selected patients.

Histologic development of the mammalian cochlea has been studied by many investigators. In 1978, Li reported on a preliminary scanning electron microscopic study of hair cell development in the embryonic mouse cochlea. The present study further examines the surface morphology of the embryonic cochlea.

Four patients with spastic dysphonia refractory to speech and phychiatric therapy were treated by crushing the recurrent laryngeal nerve. Vocal cord paralysis was produced in all patients. Vocal spasticity subsided in all patients. Vocal cord motion returned in four to six months. Three of four patients remained free of spasticity for a minimum of 24 months.

The clinical manifestations of 29 recently encountered sarcomas of the head and neck were analyzed in an attempt to define more accurately the diagnostic characteristics and therapeutic responses of these unusual tumors. The host factors of age, sex distribution, race, habits and associated features differ sufficiently to distinguish the sarcoma from the carcinoma population. In addition, the clinical course of sarcoma patients as monitored by mode of presentation, site of involvement, tumor histology, diagnostic features and certain elements of management and outcome, further indicates that these tumors can be defined and managed as a distinct group of lesions. A review of the recent literature supports the major conclusions of this study

Olfactory neuroblastoma is an uncommon malignant tumor arising from olfactory epithelium. Generally considered to be a tumor of slow growth, it varies in aggressiveness and may cause death by distant metastasis or local invasion. The pathologic diagnosis is difficult, and this tumor is often erroneously diagnosed. Nine previously unreported cases are presented, and a review of the various treatment modalities and course of the disease is given. Maximum therapeutic succes is best achieved by radical excision followed by a full course of radiation. Because of the high incidence of local recurrence (46%) and slow growth, patients should be followed up closely for life.

We describe a technique of tracheostoma construction utilizing a deltopectoral flap. This method can be used when entry into the superior mediastinum and low tracheal resection is required.

An improved fiberoptic laryngoscope is connected to Timcke's stroboscope. The laryngoscope gives a magnified view of 2x and is prefocused from 5 cm to infinity. The combination of the stroboscope and the laryngoscope gives an excellent slow-motion view of the vocal fold movement.

We have successfully treated two patients with symptomatic pneumatosis cystoides intestinalis using a high FIO2 delivered by face mask, with administration interrupted at meal times. While we advocate oxygen therapy for this disease, caution must be taken to avoid the complications of high PaO2, namely proliferative and fibrotic lung changes. Close attention should be paid to the development of increasing cough, dyspnea and shortness of breath. As the frequency of the diagnosis of pneumatosis cystoides intestinalis increases, the success of high inspired oxygen as therapy should be recognized
