Modified house tympanoplasty for successful closure of near-total tympanic membrane perforations.

Objective: To demonstrate the use of a modified House technique in the successful closure of near-total tympanic membrane perforations.

Methods: This is a retrospective analysis over a 25-year span of the senior author's experience with a particular technique of closing large tympanic membrane perforations. The charts of patients were reviewed and the data were analyzed.

Sinusitis. Diagnostic methods.

Sinusitis, which primarily involves the anterior ethmoid air cells, can spread to the larger sinus cavities to cause acute and chronic secondary infection. Endoscopic and computed tomographic techniques enable earlier diagnosis and treatment of sinusitis and permanent cure. Primary care physicians should try to identify the disease before it reaches a stage where endoscopic control becomes difficult.

Endoscopic diagnosis, treatment, and follow-up of tumours of the nose and sinuses.

In the last decade, a great deal of attention has been focused on functional endoscopic nasal surgery for chronic sinus disease. There has been less emphasis in regard to the obvious advantages of the endoscope for diagnosis, treatment, and follow-up of tumours of the nose and paranasal sinuses. This presentation discusses in detail the reasons that the endoscopic technique is useful when applied to diagnosis of benign or malignant lesions in these areas.

Ultrasound in the diagnosis and management of peritonsillar abscesses.

This study was conducted to determine the possibility of using an intracavitary ultrasound probe to differentiate between peritonsillar cellulitis and peritonsillar abscesses. Three volunteers and 11 of 12 patients were successfully scanned. The ultrasound method successfully demonstrated four cases of peritonsillar cellulitis and seven cases of peritonsillar abscesses.

Diagnosis of peritonsillar abscess: value of intraoral sonography.

Objective: Clinical differentiation of peritonsillar abscess from peritonsillar cellulitis can be difficult and often relies on blind needle aspiration of the tonsillar fossa to locate pus. The objective of this study was to establish a noninvasive and reliable sonographic technique for differentiating peritonsillar abscess from peritonsillar cellulitis in equivocal cases and to thereby avoid unnecessary needle aspiration.

Subjects And Methods: The study population included three healthy volunteers and 18 patients with clinically suspected peritonsillar abscess.

Long-term results of uvulopalatopharyngoplasty for snoring.

Snoring is a disease of listeners and one which can cause significant disruption in an otherwise peaceful household. Uvulopalatopharyngoplasty (UPPP) was initially described in 1981 for the treatment of obstructive sleep apnea, and since that time only one large series has evaluated it as a treatment for snoring. Various therapeutic strategies have been described for the treatment of snoring, but UPPP seems to hold the most promise.

Upper airway measurements predict response to uvulopalatopharyngoplasty in obstructive sleep apnea.

Although uvulopalatopharyngoplasty relieves obstructive sleep apnea in the majority of patients, the factors that determine a successful response are not well defined. To determine whether preoperative awake upper airway measurements predict the response to uvulopalatopharyngoplasty, presurgical lateral cephalometric radiographs were evaluated on 60 consecutive patients with symptomatic obstructive sleep apnea. Patients underwent overnight polysomnograms before uvulopalatopharyngoplasty and 3 months afterwards.

Treatment of obstructive sleep apnea by uvulopalatopharyngoplasty.

Although uvulopalatopharyngoplasty has been proposed as a treatment for obstructive sleep apnea, there is limited objective data concerning its efficacy. We have examined 40 patients with moderate to severe obstructive sleep apnea before and 3 months following uvulopalatopharyngoplasty. A standardized questionnaire and detailed overnight sleep study were performed before and after surgery.

Nasal septal perforations.

The etiology, symptoms, and size of 90 nasal septal perforations subjected to corrective surgery were assessed, indicating significant parameters of closure technique which should improve longterm prognosis. The use of bilateral nasal septal mucosal flaps in conjunction with an autogenous interposition graft provided for optimal results in small and medium sized (less than 20 mm) perforation closure.

Experiences with the homograft tympanic membrane.

Forty-three patients who underwent tympanoplasty with the use of a homograft tympanic membrane are reviewed. These procedures were performed by 10 different surgeons over a period of six years. The success rate of tympanic membrane closure, hearing results, and incidence of complication were studied.

T3 and T4 carcinoma of the larynx--a retrospective study.

T3 and T4 lesions of the larynx were reviewed and the five year survival figures compared for radiotherapy, surgery, and combined therapy. Glottic T3N0M0 lesions gave an acceptable five year survival figure of 66 per cent. Radiotherapy is advised as the modality of treatment for T3N0M0 lesions.

Tattoo removal with the carbon dioxide laser.

Our preliminary experience with tattoo removal utilizing the carbon dioxide laser at the Vancouver General Hospital is reviewed. We developed the method by trial and error until we produced a system yielding an acceptable procedure time with good results.

The pathogenesis, differential diagnosis, and treatment of malignant otitis externa.

Three cases of malignant external otitis with varied clinical causes are presented. It is most important to suspect the condition in any diabetic who has external otitis refractory to the usual treatment. Once the diagnosis is made, aggressive medical management is imperative to prevent progression of the disease.

Brown tumor of the maxilla due to secondary hyperparathyroidism.

The paper describes a patient with brown tumor of the maxilla caused by secondary hyperparathyroidism, and gives an account of pathophysiology and management.

British Columbia ear bank.

The B.C. Ear Bank was established in 1974 as a temporal bone laboratory devoted to the study of hearing loss and histological examination of temporal bones.
