Patients may have voicing abnormalities before thyroid surgery is performed. Surgery may improve or worsen the voice irrespective of the pre-operative voice status.

Background The plunging ranula is a relatively uncommon phenomenon which represents a mucus escape reaction occurring from disruption of the sublingual salivary gland. We present a series of 20 patients managed at Green Lane Hospital (Auckland, New Zealand) over a 9‐year period. Methods A retrospective review of 13 patients with this condition was undertaken, and a prospective study was conducted on 7 patients. Information was collected on age, sex, ethnic origin, history of onset, predisposing factors, treatment, and outcome of treatment. Results The patients were all young adults with a median age of 31 years. The sex distribution was relatively equal, with 11 men and 9 women. All patients were Maori or Pacific Island Polynesians. Six patients gave a clear history of preceding trauma to the neck or oral cavity. Two recurrences were seen, both in patients who had had the sublingual gland excised via a cervical approach. Five patients sustained lingual nerve damage during surgery. Full function recovered in four patients, but the complication was still present in the fifth patient at 2 years, after which he was lost to follow‐up. Conclusions Plunging ranulas appear to occur with greater incidence in the Maori and Pacific Island Polynesian populations. The precise etiology of their predisposition is unknown, although local trauma or inherent mylohyoid dehiscences may play important roles. Removal of the sublingual gland via either a cervical or intraoral approach is important in the management of this condition. Excision of the pseudocyst is probably unnecessary and places surrounding structures at risk of damage, but a biopsy of the pseudocyst wall is important to confirm the diagnosis. © 1998 John Wiley & Sons, Inc.

We advocate that patients be managed postoperatively according to the presence or absence of these given predictors to reduce occurrence of fistula formation in the high-risk group.

Selection bias, technique and tube type appeared to influence the complication rate in the present review. Percutaneous endoscopic gastrostomy will remain the authors' preferred method while PRG will be reserved for those cases for whom endoscopic placement is deemed to be impractical.

A head and neck ultrasound-guided fine-needle aspiration clinic was set up to determine the role of ultrasound and ultrasound-guided fine-needle aspiration in the evaluation of patients with lesions in this region. One hundred ninety-five lesions were biopsied by ultrasound-guided fine-needle aspiration in 203 patients. Ultrasound detected 2 or more lesions in 14 (48%) of 29 patients with a clinically solitary thyroid nodule. Three (8.8%) of 34 lesions thought to be within the parotid gland were determined to be external. A pronounced learning curve was evident in the technique of ultrasound-guided fine-needle aspiration, particularly for nonpalpable disease. Adequacy of sampling for each 3-month period was 71%, 89%, and 94%, respectively. Seventy-four percent of central aspirations were satisfactory compared to 54% of peripheral aspirations. Ultrasound-guided fine-needle aspiration did not alter the clinical staging of metastatic neck disease in 8 patients having 10 neck dissections but proved useful in detecting nodal recurrence in 3 irradiated necks that did not proceed to surgery. The smallest node to harbor malignancy had 4-mm maximal axial diameter. We conclude that ultrasound and ultrasound-guided fine-needle aspiration are valuable adjuncts to the clinical examination.
