BackgroundThe literature contains diverse and sometimes contradicting results about wound seroma following thyroidectomy. This is probably due to the subjective clinical estimation of seroma, or due to failure to differentiate between the occurrence of subcutaneous (SC) and deep wound collections. This work aimed at objectively investigating the factors affecting subcutaneous and deep wound seroma after thyroidectomy.MethodsThe relation between various operative and clinico-pathological factors and the collection formation was prospectively analyzed in a cohort of 100 patients after conventional thyroidectomy. Wound seroma was assessed clinically and via high-resolution ultrasonography at 24 h, 48 h and two weeks postoperatively. Sonographically detected collections were expressed as SC and/or deep wound collections according to the relation to strap muscles.ResultsOperative duration was the only independent factor significantly affecting the incidence of clinical seroma. Older patients (>40ys) showed significantly larger volumes of early SC collections. Early postoperative pain was significantly related to drain insertion, to the occurrence of clinical seroma and to the volume of SC collections.Sonographically, suction drains and shorter operative durations resulted in significantly less amount of deep collections. Suction drains did not result in less amount of SC collections or in a lower incidence of clinical seroma.ConclusionsOperative duration is the only independent factor significantly related to clinically-detected postoperative seroma with its subsequent postoperative pain. Especially in elderly patients, a flapless technique would be recommended as these patients developed larger volumes of SC collections with subsequent higher pain scores, even if seroma was not clinically detected.

Eleven patients were referred with fTC, eight of whom had undergone subtotal thyroidectomy for an undiagnosed well-differentiated thyroid cancer (DTC) in another institution. The final pathological diagnosis showed (DTC, n = 3), poorly differentiated thyroid cancer (n = 5), anaplastic cancer (n = 2), and medullary thyroid cancer (n = 1). Extensive resections and reconstruction using flaps (pectoralis major, n = 6; deltopectoral, n = 1; sternocleidomastoid, n = 1) were undertaken. Complete tumor clearance (R0) was achieved in one patient and the others had microscopic (R1, n = 6) or macroscopic (R2, n = 1) residual disease. The three patients who did not undergo operation died within one month of presentation. The latest review of the eight patients who did undergo operation ranged from 3 to 6 months, but their survival remains unknown as access for follow-up was limited.

Drain insertion in parotid surgery doesn't affect seroma or haematoma formation post-operatively. Drainless parotidectomy patients' experienced less post-operative pain and less post-operative hospital stay. The usage of a scalpel in raising the skin flap in parotid surgery resulted in more intraoperative blood loss than utilizing electrocautary in raising the skin flap. However, both techniques did not affect, flap integrity, post-operative seroma or hematoma formation .
