Preliminary results from minimally invasive video-assisted thyroidectomy.

CONTEXT AND OBJECTIVE: Minimally invasive video-assisted gasless thyroidectomy (MIVAT) has mainly been described in Italy and has been demonstrated to be a safe procedure with additional advantages regarding cosmetic results and postoperative outcome. The aim of this work is to analyze our preliminary results from minimally invasive video-assisted thyroidectomy. DESIGN AND SETTING: Retrospective study at the Head and Neck Surgery Service of Hospital Ana Costa, Santos. METHODS: Twelve patients underwent hemithyroidectomy and another three underwent total thyroidectomy by means of minimally invasive video-assisted thyroidectomy between June and September 2004. Gender, age, goiter volume, major diameter of the dominant nodule, duration of surgery, pain complaints during the first postoperative day, length of hospital stay, cosmetic result and complications were retrospectively analyzed. RESULTS: All the patients were women, with median age of 34. The median goiter volume was 16.5 ml, and the median major diameter of the nodule was 2.3 cm. Ten patients reported mild pain at the surgical site. The median scar size was 2.0 cm and all patients considered the cosmetic results excellent. The median duration of surgery was 55 minutes, all patients were discharged on the first postoperative day, and there were no complications. CONCLUSIONS: The outcome from minimally invasive video-assisted thyroidectomy is good in terms of cosmetic results, analgesia and postoperative recovery. The scar is shorter than in the conventional procedure.

Quality of life and depression in patients undergoing total and partial laryngectomy.

PURPOSE: The surgical treatment of head and neck cancer, primarily laryngeal cancer, causes sequelae and can change the patient's quality of life. The purpose of this study was to investigate the impact of laryngectomy on the quality of life regarding the functional, physical, psychological, and social aspects. METHODS: Fourteen patients underwent total laryngectomy and 16 underwent vertical partial laryngectomy. The Quality of Life Core Questionnaire (QLQ-C30) and Head and Neck (H&N35) questionnaire from the European Organization for Research and Treatment of Cancer (EORTC) were used for quality of life evaluation, while the Beck Depression Inventory questionnaire was used for the depression screen. RESULTS: In the total laryngectomy group, reported adverse effects were worsened, social and emotional function (21.3%), olfaction and taste changes (85.6%), cough (71.3%), speech difficulty (100%), and dysphagia (64.3%). Most of the patients (85.5%) judged their quality of life to be reasonable. In the partial laryngectomy group, reported adverse effects were worsened, emotional function (71.4%), speech difficulty (100%), and dysphagia (31.3%). However, most of the patients judged their quality of life to be above the general average. CONCLUSION: Despite being different surgeries, both groups experienced similar difficulties but at different levels. The quality of life was judged worse in the patients who underwent total laryngectomy.

Multiple ectopic parathyroid adenomas.

CONTEXT: Primary hyperparathyroidism is the most common cause of hypercalcemia in unselected patients. The ectopic gland locations should be known for appropriate surgical exploration and for avoiding subsequent re-exploration that would represent higher morbidity. Multiple ectopic glands are rare and present a particular challenge in parathyroid surgery. CASE REPORT: A 65-year-old female presented with nephrolithiasis. Her serum total calcium was found to be elevated. The diagnosis of primary hyperparathyroidism was confirmed by the elevated serum intact parathyroid hormone levels. Ultrasound was only successful in localizing one adenoma in the lower right gland. Technetium sestamibi scanning correctly localized the same adenoma and showed another contralateral image, lateral to the thyroid cartilage. Fiber optic laryngoscopy showed an extrinsic mass pushing against the lateral and posterior walls of the left pyriform sinus. Resonance imaging revealed a soft tissue mass. RESULTS: The patient underwent bilateral neck exploration. Histopathological examination confirmed the diagnosis of parathyroid double adenomas. The late-stage postoperative checkups were normal. DISCUSSION: Routine bilateral neck surgery should be performed as a rule. We use ultrasound and technetium sestamibi scanning as a routine for preoperative localization studies. It is helpful to have an experienced surgeon for the localization.

Videolaryngostroboscopy following frontolateral laryngectomy with sternohyoid flap.

We conducted a retrospective study to analyze the videostroboscopic findings in a group of 21 patients who underwent vertical frontolateral laryngectomy with reconstruction by use of the sternohyoid muscle flap. They had T1b and T2 glottic tumors and a follow-up of more than 1 year. Three observers analyzed the recorded videostroboscopic data. The cases in which the stroboscopic evaluation of the vocal folds was incomplete were studied in regard to the clinical staging, the supraglottic hyperfunction, and the vibratory site; the Fisher exact test was applied. The glottic closure was complete in 15 individuals, and 6 had irregular vocal gaps. The site of vibration was glottic in 10 cases, supraglottic in 7, and mixed in 4. The amplitude was normal on 4 and slightly diminished on 9 preserved sides, whereas it was moderately or severely diminished on 16 and absent on 5 reconstructed sides. The mucosal wave vibratory pattern was always totally present on 15 preserved and 5 reconstructed sides: normal or slightly diminished in the preserved vocal folds, and moderately or severely diminished in the reconstructed ones. The reconstructed vocal folds had a nonvibrating portion in 5 cases. The movement extent of the preserved side was larger than that of the other side in 8 cases, and the sides were similar in 13 cases. The symmetry was regular in 18 cases. The periodicity was always or generally regular in 9 cases. There was supraglottic hyperadduction in 16 cases, with a lateral constriction predominance. The mucosal appearance was normal in 15 patients and wet in 6 patients. The epiglottis was straight in 14 cases and crescent in 7. Mucus formation was observed in 1 patient in the posterior vibratory portion. Videolaryngostroboscopy allowed thorough evaluation of the vibratory pattern of the vocal folds in 52.4% of the patients. The supraglottic hyperadduction component and the supraglottic vocal source presented difficulty for this evaluation. The site of vibration was glottic in 47.6%, supraglottic in 33.3%, and mixed in 19.1% of the cases. The vibratory pattern was diminished on both sides, but mainly on the reconstructed one.
