Parotid space tumors of non-salivary origin.

A review of 700 parotidectomies showed that 98 procedures were performed for parotid space tumors of non-salivary origin. The clinical presentation in this group of patients did not differ significantly from the larger group of salivary tumors except for a higher incidence (12%) of the former in the younger age group. Of the 98 cases, 54 proved to be lymph node tumors, both neoplastic and inflammatory and 44 were tumors of various somatic origins. Among the latter group, bone and joint tumors, vascular lesions and some connective tissue tumors may be recognized preoperatively. Generally, however, the entire group of non-salivary tumors can be distinguished only intra-operatively, if at all. Correct recognition may lead to variations in operative techniques and extent of resection.

Hemangiomas of the salivary glands.

Five salivary gland hemangiomas in adults are reported. The feasibility of preoperative diagnosis on clinical and radiologic grounds is emphasized. Adult hemangiomas are of the cavernous type and can be differentiated from infantile capillary hemangiomas clinically as well as histologically. Cavernous hemangiomas in the adult should be treated by surgical excision.

Repair of extended laryngotracheal stenosis.

The most challenging laryngotracheal stenosis are those that exceed 5 cm in length and involve more than one area of the larynx and trachea contiguously. A successful technique for the repair of these injuries with a three-stage laryngotracheal trough was created followed by anterior tracheal wall replacement with a skin-Marlex-muscle pedicle flap.

Vertical partial laryngectomy for glottic carcinoma with posterior subglottic extension.

Posterior subglottic extension of glottic carcinoma has been a contraindication for partial laryngectomy because of the proximity of the cricoid cartilage. Resection of the upper portion of the posterior aspect of the cricoid is necessary for adequate tumor resection but is complicated by persistent aspiration. This paper presents a method of reconstruction following partial posterior cricoid resection.

Laryngeal nerve crush for spastic dysphonia.

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.

Olfactory groove meningioma with paranasal sinus and nasal cavity extension: a combined approach.

A 58-year-old man had an enlarging right fronto-orbital mass. A biopsy specimen of a right nasal cavity tumor was reported as meningioma. Preoperative evaluation including skull roentgenograms, tomograms of the paranasal sinuses, brain scan, computerized axial tomography, and carotid angiography substantiated a large subfrontal mass with paranasal sinus and orbital extension. A combined approach through a right frontal craniotomy and right lateral rhinotomy was used for a complete removal of this tumor. A review of the literature is contained herein.

Thyroid carcinoma in a patient with a coexisting functional adenoma.

Fourteen case reports have been published in which "hot" nodules have been documented as carcinoma, with or without coexisting adenomas. The diagnosis of these lesions is difficult, since hot nodules usually represent benign disease. These carcinomas are not functional, but represent coexistence of a functional area or a malignant degeneration. Hot nodule carcinomas should be suspected in high-risk patients. A euthyroid, 31-year-old woman who, as a teenager, had radiotherapy for acne is reported. She was followed up with yearly scans for a hot nodule in the right lower lobe of her thyroid. When she was 36, a node was discovered in the right side of her neck, and carcinoma was suspected. Surgical excision revealed a papillary-follicular carcinoma adjacent to an adenoma with metastases to regional lymph nodes.

Delayed tracheal reconstruction.

An extended area of stenosis of the upper mediastinal trachea, which normally would require extensive thoracic mobilization for primary anastomosis, was corrected by resection of the manubrium with the creation of a trough. This was closed in several stages utilizing embedded Marlex mesh and regional skin flaps. The development and modifications of this technique are discussed.
