Of the large variety of tumors that may occur in the parapharyngeal space, malignant fibrous histiocytoma is one of the most rare. We present such a case and discuss the diagnosis, classification, and treatment.
Glomus intravagale (paraganglioma of the nodose ganglion and/or vagus nerve) is an unusual tumor. There are approximately 45 cases reported in the literature; the authors report four more cases. This tumor may ba associated with other paragangliomas of the head and neck, such as carotid body tumors, and may metastasize to regional lymph nodes, although the histology always appears benign.
Nondelayed regional skin flaps for reconstruction following radical ablative surgery in the head and neck have become a significant advance. Radical extirpation of large, recurrent or postirradiation persistent cancer would be prohibitive without the use of regional skin flaps in reconstruction. The incorporation of portions of rib, clavicle or scapula within a skin flap has allowed reconstruction of the mandible for both functional and cosmetic improvement.
There is a variety of tumors which may occur in the parapharyngeal space; malignant Schwannoma is one of the rarer type. The authors present such a case and discuss the clinical and microscopic diagnosis. Treatment is wide surgical excision, as recurrence rates are high and the prognosis poor.
The authors describe the use of the infrahyoid ("strap") muscles as a muscle transposition flap to obliterate the "dead space" created during resection of the anterior floor of the mouth for carcinoma concomitant with suprahyoid neck dissection or radical neck dissection. The flap is particularly useful if the mandible is partially resected and immediately stabilized with a steel pin or bolt.
For hundreds of years various types of sutures and threads have been placed in the human body by surgeons. The technique of thread augmentation involves the use of colorless absorbable (Vicryl) and non-absorbable (Neurolon) suture material on a long, straight Keith needle tunneled subdermally beneath prominent facial wrinkles in an effort to make the deep grooves less severe and to augment atrophic areas about the lips and oral commissures. This may be done as an isolated procedure or as an ancillary procedure at the time of a blepharoplasty or cervicofacial rhytidectomy.
