Dilemmas in the management of chronic nasal and sinus inflammatory diseases of unknown etiology.

The diagnostic criteria and therapeutic regimens for upper airway necrotizing diseases such as Wegener's granulomatosis, polymorphic reticulosis, and the recently described idiopathic midline destructive disease have been better defined and clarified in the past decades. Despite an improved understanding of the various disease processes, there continues to be difficulty in establishing an early diagnosis before proceeding with prompt treatment to minimize loss of function and cosmetic deformity. To achieve these goals, we have expanded the indications for the use of the cytotoxic drug, cyclophosphamide, in those patients whose clinical and histologic presentations are suggestive of Wegener's granulomatosis, but in whom a specific diagnosis has not been confirmed by biopsy specimen. We have seen ten patients with upper airway lesions of a chronic inflammatory nature over the past six years at the Medical College of Wisconsin affiliated hospitals. Only three of these have had a definitive histopathologic diagnosis of Wegener's granulomatosis made prior to the initiation of cytotoxic therapy. Six have undergone treatment under our expanded criteria without a prior definitive diagnosis. Five of these have had arrest of the disease process, and one has had no response to therapy. One patient was not treated. There have been no serious side-effects from cyclophosphamide therapy in these patients.

Sudden sensorineural hearing loss: operative complication in non-otologic surgery.

Sudden sensorineural hearing loss is a well recognized phenomenon in otologic practice with both viral and vascular etiologies being supported. However, sudden hearing loss as a complication of non-otologic surgical procedure is a seldom reported and rare phenomenon. Five cases of unilateral sudden sensorineural hearing loss which are time related and probably causally related to non-otologic surgery are presented. Two cases underwent open heart surgery and support previous reports of hearing loss secondary to cardiopulmonary bypass procedures. Three noncardiac cases are also reviewed. None of these patients had prior otologic disease which would predispose to a sudden hearing loss, and no intraoperative or postoperative complication was specifically noted as a cause of the hearing loss. The literature is reviewed and attention is drawn to the problem. We wish to encourage further reports and to recommend early identification and treatment in those cases related to cardiopulmonary bypass.

Adenoid cystic carcinoma of the submaxillary gland.

A review of submaxillary gland neoplasms over a 21 year period revealed 15 malignancies and 7 benign tumors. All of the malignancies occurred in females, and 11 of these were adenoid cystic carcinoma. Two of the 11 were found to have infiltrating ductal carcinoma of the breast (1 pre and 1 postdiagnosis of the submaxillary carcinoma) and 3 had benign breast disease. While previous reports have suggested an association of parotid gland neoplasia and breast cancer, this is the first known report of an association between adenoid cystic carcinoma of the submaxillary gland and cancer of the breast. The discussion of adenoid cystic carcinoma of the submaxillary gland emphasizes the increased frequency of this disease in females, its association with breast disease, and also experimental submaxillary gland neoplasia.

Rhinitis medicamentosa.

The diagnosis of rhinitis medicamentosa was made in 130 patients seen over a 10 year period from July 1967 to June 1977. There was an incidence of 1% in our otolaryngological practice. Patients had been taking the causal medication for an average of 21.4 months. There were 73 males and 57 females with the peak incidence in young and middle-age adults. The primary offending medications were decongestant nasal sprays in 85 patients, decongestant drops in 33, and a combination of these drugs in 12 patients. The major reasons for self-medication were 1. deviated nasal septum in 40 patients, 2. an acute upper respiratory infection in 33, 3. allergy in 18, 4. miscellaneous causes in 24 and 5. unknown in 15 patients. The initial management in addition to avoidance of the medication consisted of systemic antibiotics, decongestants, antihistamines, and sedatives depending on the severity of the rhinitis and the presence of secondary infection. Later treatment consisted of correction of the deviated septums, allergic management, and supportive care. Eight patients were considered to have complications of the disease by development of chronic ethmoiditis and nasal polyposis. The pharmacologic properties of the causal agents are thoroughly reviewed as they relate to the pathogenesis of this disease. It is felt that the ready commercial availability and limited clinical value of the topical nasal sprays and drops represents a certain risk to all patients using them.

Bone and liver scans in patients with head and neck carcinoma.

The initial evaluation of patients with malignant tumors of the head and neck must include an attempt to determine the presence or absence of distant metastases so that the patient's tumor can be accurately staged and appropriate treatment planned. To determine the value of routine bone and liver scans in detecting distant metastases, the records of 169 patients with head and neck carcinoma, on whom such scans were performed, were reviewed retrospectively. No true positive liver scans were found and the incidence of true positive bone scans was only 2%. It is felt, therefore, that routine scanning is not a worthwhile procedure and we recommend that liver and bone scans be reserved for those patients with advanced primary tumors, with regional node metastases or with clinical or laboratory evidence of liver or bone involvement.

Vocal cord fixation in laryngeal carcinoma.

The 1962 TNM classification (T, tumor and extent; N, regional lymph node metastasis, M, distant metastasis) did not emphasize vocal cord fixation in staging. In the revision of 1972, lesions with partial fixation were classified T2, stage II, and those causing fixation were T3, stage III. The therapeutic results in 39 patients with fixed cords revealed a determinante five-year survival of 41% and an absolute of 23%. These statistics support the validity of the 1972 classification. Careful evaluation of vocal cord mobility prior to selection of therapy is stressed.

Stomal recurrence following laryngectomy.

The extent of subglottic involvement and preoperative tracheostomy, appear to be the most important causative factors in peristomal carcinoma. Our case histories have demonstrated tumor foci in a tracheopstomy tract and in pretracheal lymphatics. Once established, the prognosis of the lesion is grave. Radiation and chemotherapy offer only limited palliation, and extensive resection offers the best chance of cure at the present time. Prophylactic measures such as avoiding a preliminary tracheostomy, meticulous paratracheal dissection, and microscopic control of the resected margins of the surgical specimen may reduce the incidence of peristomal carcinoma.
