Abstract
The excision of distal digital glomus tumors has traditionally been performed directly over the involved nail bed. This can lead to nail deformities that are often unacceptable for the surgeon and the patient. The authors describe their experience with successful excision of digital glomus tumors using a lateral subperiosteal approach, which creates a dorsal flap. In 29 years, 19 patients were diagnosed with digital glomus tumors. All patients underwent excision using the lateral subperiosteal approach. The mean tumor size was 0.52 cm. The tumors were located on the pulp of the distal phalanx in two patients (10.5 percent) and subungually in 17 patients (89.5 percent). In all patients, preoperative clinical diagnosis was confirmed postoperatively with the biopsy result. Complications occurred in only two patients and included one paronychia and one temporary nail loss. The overall recurrence rate was 15.7 percent. All patients remained asymptomatic after surgery and regained full active and passive range of motion. There were no nail deformities by this approach. This technique represents a safe and effective approach to excising digital glomus tumors.
