Suction-assisted lipectomy is a valuable method of aesthetic recontouring of the neck. We report the successful use of suction-assisted lipectomy as an adjunctive procedure at the time of tracheostomy in the treatment of obese patients with severe obstructive sleep apnea. This functional procedure helps to maintain tracheostomy patency during sleep.

This study is a retrospective review between 1976 and 1986 of 12 patients with T1(1) and T2(11) NO supraglottic cancers which were managed by a method that utilized planned preoperative radiotherapy (45-51 Gy) to the primary and bilateral necks. If adequate tumor response (greater than 75% reduction in size) was noted by laryngoscopy, therapy was completed at levels of 65-70 Gy to the primary. If a lesser tumor response was noted, the patient underwent supraglottic laryngectomy. Six patients completed primary radiotherapy (RT-RT) and six patients underwent supraglottic laryngectomy (RT-SG). There was evidence of residual tumor in three of six RT-SG patients. No tumor recurred at any site. Laryngeal function was preserved in all patients. Absolute survival was 58% at 67 months. This approach is oncologically sound and permits maximal laryngeal conservation.
We report on the perioperative and postoperative course of 47 patients with severe obstructive sleep apnea, who underwent tracheostomy by use of a silicone tracheal cannula developed by Dr. William Montgomery. Our initial experience with the first 20 of these patients (presented in 1982) was quite favorable because of the ease of insertion and care, a high degree of patient acceptance, and infrequent complications. With our current sample, larger experience, and more prolonged follow-up, we noted that symptomatic granulation tissue formation, with or without wound infection, occurred more frequently than was initially appreciated. In 21% (10 of 47) of the cases, the only way to resolve this problem was to remove this device and replace it permanently with a metal (or other type) tracheostomy tube. Other complications included tracheal narrowing and cannula malpositioning and fragmentation. This full report lists in detail the incidence of complications associated with our use of this cannula and modifications which may lessen these.

Angiosarcoma (AS) is a rare malignant tumor of the skin and soft tissues. Due to this lesions's histopathologic similarity to other soft tissue and skin neoplasms, several names had been previously used to describe AS. In the following article, we present a comprehensive review of the literature and prior studies pertaining to AS. The purpose of this article is to provide the reader with a better understanding of the causative factors, clinical findings, and histological features of this uncommon but potentially lethal tumor. Furthermore, we discuss present therapeutic options and outcomes as well as summarize recent advances in AS tumor biology and cytogenetics.
