Schneiderian papilloma of the nose and paranasal sinuses: the University of Ottawa experience.

Schneiderian papillomata of the nose and the paranasal sinuses are uncommon neoplasms. Although histologically benign, malignancy can occur. The likely etiologic agent is the human papilloma virus. We reviewed the cases treated at University of Ottawa-affiliated hospitals from 1969-1989. There were 35 patients consisting of 26 men and nine women with an average age of 55.8 years. The most common presenting symptom was unilateral nasal obstruction (71.4%). This was caused in most cases by an ipsilateral polypoid mass (82.9%). CT scan study was helpful in delineating the size and extent of the lesion. Four cases of malignancy were found (11.4%). Whether malignant transformation had occurred or whether a synchronous or metachronous malignancy had been serendipitously discovered is open to debate. Thorough examination with biopsy is mandatory to obtain a definitive histologic diagnosis. Intranasal papilloma-plucking (polypectomy) is useful for biopsy purposes but grossly inadequate as definitive treatment. The high recurrence rate is due to inadequate resection. Radical surgery consisting of medial maxillectomy via the lateral rhinotomy approach has the lowest recurrence rate (7.1%) and is the treatment of choice.

Otolaryngology-head and neck surgery in the Canadian military: practice trends.

The practice of medicine in the Canadian military is poorly publicized except in times of war. The specialty of otolaryngology-head and neck surgery is not well known, even in medical circles. To correct this deplorable ignorance, a review was conducted on the otolaryngologic activities within the Canadian Forces. This revealed a dynamic specialty whose many contributions warrant acknowledgment. Starting with Major-General M.J.C.E. Fiset, who was the first such specialist in Canada, military otolaryngologists have maintained excellent standards of medical practice for the benefit of the Canadian soldier. This paper traces the development of military otolaryngology in Canada. Trends in the practice of this versatile specialty are presented.

Percutaneous tracheostomy: ready or not?

A novel approach to tracheostomy has recently been introduced, based on the Seldinger guide-wire technique. A well-packaged percutaneous tracheostomy kit promises a rapid and safe alternative to the traditional surgical tracheostomy. At the National Defence Medical Centre, this percutaneous approach was tried on four patients. Deficiencies in the kit instruments were discovered which, with the expected "learning curve," led to unexpected difficulties. Thus, the promise of percutaneous tracheostomy remains as yet unfulfilled.

Surgery for snoring.

Snoring is a common obnoxious disturbance in human society. Although considered a mere nuisance by most, it can have significant social and medical effects. Snoring has caused marriage breakdown and murder. It can lead to hypertension, heart failure, and the obstructive sleep apnea syndrome. Since Ikematsu developed palatopharyngoplasty (PPP) in 1952 and Fujita introduced it to North America in 1981, numerous reports have alluded to its efficacy in the management of snoring. From June 1986 to February 1988, 110 PPP operations were performed at The Wellesley Hospital, University of Toronto. Of these, 58 patients responded to review and questionnaire. Elimination or improvement of their snoring was reported by 75.9% of patients. Complications encountered are discussed. We conclude that palatopharyngoplasty (PPP) is a safe and effective technique in the treatment of problematic snoring.

Fibrin glue in facial plastic and reconstructive surgery.

Fibrin glue has gained extensive use in Europe in the past decade but remains fairly new to North America. Fibrin glue physiology, its historical background, experimental findings, its present uses and the question of safety are addressed. Results of its use in facial plastic and reconstructive surgery at the Toronto Western Hospital are presented. The authors conclude that fibrin glue is a safe bioadhesive and sealant. It is an excellent adjunct but not a substitute for good surgical techniques.
