Sudden death after major head and neck surgery

PURPOSE OF REVIEW

This review will discuss the mortality after major ear, nose and throat surgery, particularly sudden death. It will also discuss the postoperative follow-up of patients.

RECENT FINDINGS

Sudden death is a rare event after major ear, nose and throat surgery, and occurs mainly during the first three postoperative days.

SUMMARY

In more recent studies, the mortality rate after neck dissection was below 4%, which is at a lower value than reported in previous studies. Sudden deaths have been described, however, mainly during the first three postoperative days. Alcoholism and perioperative hypotension are two predictive factors for cardiac complications. Careful follow-up of these patients during the early postoperative period should be performed to reduce the mortality by shortening the delay of care.

Sentinel node biopsy in squamous cell cancer of the oral cavity and oral pharynx: A diagnostic meta-analysis

BACKGROUND

The sentinel node biopsy concept has been gaining support in the head and neck cancer literature during only the last few years, and several pilot studies have been published. This procedure aims to avoid unnecessary treatment to the clinically negative neck by identifying the patients with occult neck disease.

METHODS

We performed a systematic review and a diagnostic meta-analysis of all published literature regarding sentinel node biopsies in head and neck cancer until December 2003 using established guidelines. Using the pooled sensitivity rates obtained from the meta-analysis and treatment outcomes from published literature, we created a decision analysis model to identify the treatment arm with better payoffs.

RESULTS

A total of 301 patients with oral cavity primary tumors and 46 patients with oropharyngeal primary tumors from 19 articles were included for the meta-analysis. The pooled sensitivity result using the random effects model was 0.926 (95% confidence interval, 0.852-0.964). The cumulative payoff for the sentinel node biopsy arm was lower than that for the elective node dissection arm by about 1%. The payoffs were assigned for the recurrence and mortality rates only and did not take into account the morbidity caused by the procedures.

CONCLUSIONS

The sentinel node biopsy procedure has shown high sensitivity rates in pilot studies for oral and oropharyngeal squamous cell cancer across the globe and is reliable and reproducible. This study provides a firm evidence base for forthcoming trials on the role of sentinel node biopsy in head and neck cancer.
