[Evaluation of shoulder function after repairing head and neck defects with supraclavicular flap].

Abstract

Objective: To evaluate the shoulder function in patients after repair of head and neck defects with supraclavicular flap. Methods: A retrospective analysis was performed on 56 patients (54 males, 2 females, aged 35-74 years old) who received the repair of head and neck defects with supraclavicular flaps at Department of Otorhinolaryngology Head and Neck Surgery of Beijing Tongren Hospital, Capital Medical University in January 2013-December 2020. The areas and types of flaps, disruption or infections of the incision at the donor sites and other postoperative complications were recorded. Quick disabilities of the arm, shoulder and hand (Quick-DASH) was used for evaluating the shoulder functions in 43 patients conforming to the standard for evaluation of the clinical functions of shoulders and upper limbs, to compare the postoperative upper limb functions between patients treated with clavicular flaps and patients with acromion flaps. Meanwhile, 30 patients who received bilateral neck lymph node dissection over the same period of time were selected for a comparative evaluation of the donor sides (observation group) and the opposite sides (control group). Data were processed with SPSS 22.0. Results: The areas of obtained supraclavicular flaps were (4-10) cm × (10-18) cm. Three patients (5%) showed the defect widths of 8-10 cm at the donor sites, which couldn t be sutured directly, received the repair of their shoulder defects with partial flaps. Defects in other patients were sutured directly. After surgery, 3 patients (5%) suffered from disruption of the acromion incision, which healed after 2 weeks of local dressing. The follow-up time was 6-43 (27±14) months. All patients expressed no dissatisfaction with the appearance. Among 43 patients, 28 (65%) were clavicular type and 15 (35%) were acromion type. The acromion type showed average motor ability and Quick-DASH scores higher than the clavicular type [(average motor ability: (14.4±4.7) vs. (11.8±3.1), t=2.105, P=0.048; Quick-DASH: (16.9±11.6) vs. (12.2±7.1), t=2.284, P=0.033]. Among 30 patients who received bilateral neck lymph node dissection over the same period of time, the observation group showed higher average motor ability, local symptoms and Quick-DASH scores than the control group [average motor ability: (13.4±5.8) vs. (9.8±4.2), t=3.024, P=0.004; average local symptoms: (4.1±1.0) vs. (3.4±1.0), t=2.537, P=0.014; Quick-DASH: (15.6±14.7) vs. (5.2±11.1), t=3.106, P=0.003]. Conclusion: Shoulder dysfunction exists after treatment with supraclavicular flap, which is related to the flap type.
