RESUMEN
BACKGROUND: This study investigated the effects of reconstruction of hypopharyngeal non-circumferential defects with a submental island flap after ablation of hypopharyngeal carcinoma. OBJECTIVES: The purpose of our study was to identify advantages and limitations of the submental flap for reconstruction of non-circumferential hypopharyngeal defects. METHODS: A total of 27 patients who had stage II-IV hypopharyngeal cancer and underwent pharyngeal reconstruction with a submental flap by the senior author in both Department of Otolaryngology Head Neck Surgery, Chinese PLA General Hospital and Department of Otolaryngology Head Neck Surgery, Beijing Friendship Hospital, Capital Medical University. RESULTS: 96.3% (26/27) cases of submental island flap survived. There were two pharyngocutaneous fistulas, one recovered spontaneously, and the other was associated with flap necrosis, underwent neck debridement and flap removal. All except for one patient had decannulation of their nasogastric tube 2 weeks postoperatively. There was no evidence of a stricture or stenosis of the laryngopharynx, nor any sign of aspiration, except for one with esophageal inlet stricture caused by radiotherapy. There were two cases of obvious paraesthesia pharynges due to beard growth at the submental flap after reconstruction. 63.0% (17/27) patients are alive and 37% (10/27) have died of disease. The 3-year survival rate is 56.3% and the 5-year survival rate is 50.0%. CONCLUSION: The submental flap reconstruction for moderately sized non-circumferential hypopharyngeal defects is a recommended treatment option.

Parathyroid surgery is the acceptable definitive treatment for primary hyperparathyroidism (pHPT) due to parathyroid adenoma. Open mini-incision parathyroidectomy (O-MIP) has an excellent cure rate and minimal morbidity. We aim to demonstrate the safety, efficacy and subjective patient satisfaction of O-MIP and investigate the accuracy of pre-operative radiological localisation in relation to operative findings. A retrospective review of patients who underwent O-MIP for pHPT due to solitary parathyroid adenoma from April 2006 to August 2012 was performed. All patients were initially investigated by an endocrinologist to confirm pHPT with pre-operative localisation imaging using ultrasound scan (USS) and 99mTc-sestamibi (MIBI). One hundred and fifty consecutive patients were included with a median age of 62 years. Pre-operative USS and MIBI scans were concordant in 71 % of cases. In combined modality (USS and MIBI), localisation was 94.8 % accurate. There was 95.5 % identification of parathyroid tissue confirmed by intra-operative frozen section. Ninety-one percent of patients were treated as a day case. The median operative time was 60 min. The mean pre-operative calcium level was 2.98 mmol/l, and the short-to-medium term mean calcium level was 2.49 (Paired t test, p < 0.001). There was no significant complication. O-MIP confers significant advantages over the traditional gold standard treatment of bilateral neck exploration. Accurate localisation is the key to successful O-MIP. In experienced hands, ultrasound and MIBI may be the only pre-operative investigations required for accurate localisation.
