ABSTRACT: Although local anesthesia usually is used in surgical procedures, field or nerve blocks can provide more effective anesthesia in some situations. In a field block, local anesthetic is infiltrated around the border of the surgical field, leaving the operative area undisturbed. In field blocks, epinephrine may be added to the anesthetic to enhance vasoconstriction and prolong the duration of anesthesia. In a nerve block, anesthetic is injected directly adjacent to the nerve supplying the surgical field. A review of regional anatomy and the location of nerves and other important structures is essential before administering the injection. Systemic toxicity is rare with regional anesthesia and can be prevented by using the smallest dose possible and aspirating before the injection. Supraorbital, supratrochlear, infraorbital, and mental nerve blocks can provide adequate anesthesia in procedures on parts of the face. Field block also may be considered when operating on the ear or lips.

The Adult Neck Mass - Article
ABSTRACT: Family physicians frequently encounter neck masses in adult patients. A careful medical history should be obtained, and a thorough physical examination should be performed. The patient's age and the location, size, and duration of the mass are important pieces of information. Inflammatory and infectious causes of neck masses, such as cervical adenitis and cat-scratch disease, are common in young adults. Congenital masses, such as branchial anomalies and thyroglossal duct cysts, must be considered in the differential diagnosis. Neoplasms (benign and malignant) are more likely to be present in older adults. Fine-needle aspiration and biopsy and contrast-enhanced computed tomographic scanning are the best techniques for evaluating these masses. An otolaryngology consultation for endoscopy and possible excisional biopsy should be obtained when a neck mass persists beyond four to six weeks after a single course of a broad-spectrum antibiotic.
