Current applications of ultrasound-guided wire localization in head and neck surgery

Ultrasound-guided wire localisation: a GPS for hidden head and neck tumours? A case series

Objectives

Ultrasound-guided wire (USGW) localisation for small non-palpable tumours before a revision head and neck surgery is an attractive pre-operative option to facilitate tumour identification and decrease potential complications. We describe five cases of pre-operative USGW localisation of non-palpable head and neck lesions to facilitate surgical localisation and resection.

Methods

All patients undergoing pre-operative USGW localisation for non-palpable tumours of the head and neck region at London Health and Sciences Center, London, Ontario, Canada, were included. All the USGW localisations were performed by the same interventional radiologist, and the surgeries were performed by fellowship trained head and neck surgeons.

Results

Five patients were included. All patients were undergoing revision surgery for recurrent or persistent disease. All successfully underwent a pre-operative USGW localisation of the non-palpable lesion before revision surgery. All lesions were localised intra-operatively with no peri-operative complications.

Conclusions

USGW localisation is a safe and effective pre-operative technique for the identification of small non-palpable head and neck tumours.

Ultrasound-guided hookwire localization of non palpable cervical lymphadenopathy: A case-control study of operative time

OBJECTIVE

We aimed at evaluating the impact of ultrasound-guided (US) hookwire localization of nonpalpable cervical lymphadenopathy on operating time.

DESIGN AND METHODS

Retrospective case control study (January 2017 and May 2021) of 26 patients with lateral nonpalpable cervical lymphadenopathy undergoing surgery with (H+) and without (H-) per operative US-guided hook-wire localization. Operative time (general anesthesiology onset, hookwire placement, end of surgery) and surgery-related adverse events data were collected.

RESULTS

Mean operative time was significantly shorter in H+ group versus H- group (26 ± 16 min vs. 43 ± 22 min) (p = 0.02). Histopathological diagnosis accuracy was 100% versus 94% (H+ vs. H-, p = 0.1). No significant between group difference in surgery-related adverse events was reported (wound healing, p = 0.162; hematomas, p = 0.498; neoplasms removal failure, p = 1).

CONCLUSION

US-guided hookwire localization of lateral nonpalpable cervical lymphadenopathy allowed a significant reduction in operative time, comparable histopathological diagnosis accuracy and adverse events compared with H-.

OUP accepted manuscript

Prostate cancer is the second most frequent cancer type among men worldwide. With the development of Radiology and Nuclear Medicine technologies, early diagnosis is increasingly common, and the possibility of using new minimally invasive techniques increases. With a narrative review of the literature, this case report describes an alternative radioisotope-guided laparoscopy technique for tumors in the peritoneal cavity. There may be benefits in associating nuclear medicine techniques in the management of patients with non-palpable tumors that are difficult to locate in the peritoneal cavity, enabling the use of less invasive and safer surgical procedures for diagnosis, staging and treatment.

Preoperative Ultrasound-guided Wire Localization of Soft Tissue Masses Within the Musculoskeletal System

Ultrasound-guided hookwire localization was initially introduced to facilitate the excision of nonpalpable breast lesions by guiding surgical exploration, thereby reducing operative time and morbidity. The same technique has since found utility in a range of other applications outside breast and can be useful within the musculoskeletal system. Despite this, there remains limited literature with respect to its technical aspects and practical utility. We describe our technique and a series of preoperative ultrasound-guided wire localizations in the musculoskeletal system to assist surgical excision of 4 soft tissue masses.
