In 75 patients with glomus tumors in the head and neck region, 57 tumors arose from the jugular bulb region, 11 from the middle ear, and seven from the vagus nerve. Thirty-seven percent (28 patients) had cranial nerve paralysis, and 14.6% (11) had intracranial tumor extension. The jugular foramen syndrome was associated with a 50% (two of four patients) incidence, and hypoglossal nerve paralysis with a 75% (three of four) incidence of posterior fossa tumor invasion. Horner syndrome and labyrinthine destruction had a 50% (two of four) incidence of a middle cranial fossa tumor invasion. The incidence of central nervous system (CNS) invasion with cranial nerve paralysis (excluding the seventh nerve) was 52% (11 of 21). Otologic findings and seventh nerve paralysis did not correlate with CNS tumor extension.

Increased mortality and arterial hypoxemia have long been associated with posterior nasal packs placed for control of severe epistaxis. Several authors have postulated a nasopulmonary reflex to partially explain this clinically observed phenomenon. In ten young, healthy subjects, using a multiparameter pulmonary evaluation, posterior nasal packs were placed and no significant changes were observed in lung volumes, flow and alveolar gas exchange, especially oxygenation. These findings suggest that aspiration, sedation, and degeneration of pulmonary function with age, not a nasopulmonary reflex, have not been adequately emphasized in previously performed studies.

Reexamination of the anterior commissure from the perspective of semantics, the anatomy of tumor spread, and connective tissue histology and embryology has reaffirmed previously published findings. In addition, this investigation of the convergence of the various structures toward the anterior commissure has led to the hypothesis that the anterior subglottic larynx may have a midline embryological origin. Whether this area should be included in the “anterior commissure” or possibly better considered as an area to which anterior commissure tumors spread is as yet undetermined.

Autogenous hyoid bone grafts for the repair of subglottic stenosis have been used successfully in canine experiments. This technique was subsequently modified for human use, and the experience in six patients over the past year at Washington University is reported. In five of the six patients, satisfactory results were obtained. Several case reports are included, and the surgical procedure is described in detail.
