Voice prosthesis insertion after endoscopic balloon-catheter dilatation in case of a stenotic hypopharyngo-oesophageal junction

Stenosis of the hypopharyngo-oesophageal junction can be a rare complication of laryngectomy and/or partial pharyngectomy and makes the insertion of voice prosthesis extremely difficult. This study describes the authors’ experiences gained by endoscopic balloon-catheter dilatation of hypopharyngo-oesophageal stenoses prior to implantation of voice prostheses in four cases. In two patients a single balloon-catheter dilatation resulted in wide enough pharyngo-oesophageal lumen on the long run. The average prosthesis wearing-times were 6.8 months in case 1 and 4.6 months in case 2, corresponding to the published literature data. In case 3, repeated dilatation of the pharyngo-oesophageal transition had proved to be unsuccessful despite taking every effort with the endoscopic balloon-catheter method. Having excised the stenotic segment, reconstruction with pectoralis major myocutaneous flap (PMMF) was indicated. Eighteen months later, a repeated restenosis was observed and a free jejunal flap needed to be performed as a final solution. In case 4, the insertion was carried out into a previously dilated jejunal free flap, which became gradually ischemic and stenotic since the major head-and neck procedure was carried out that resulted in prosthesis rejection after just 1 week. The authors emphasize that correct indication of pedicled and free flaps in head and neck reconstruction is a prerequisite from the aspect of prevention of pharyngo-oesophageal strictures. Endoscopic balloon-catheter dilatation is a safe and established method for dilatating hypopharyngo-oesophageal stenoses of different origin. The procedure provides maximum patient benefit with minimal trauma and morbidity; moreover, facilitates insertion of voice prostheses. However, a single balloon-catheter dilatation cannot always result in wide enough oesophageal lumen on the long run (case 3). Insertion of a voice prosthesis into a previously dilated ischemic jejunal segment is challenging and avoidable due to risks of complications.     

处女膜修补手术及麻醉方法的改进

目的；增大处女膜粘膜瓣的接触面，减少因麻醉造成的处女膜粘膜水肿，提高修复手术的成功率。方法：手术全部采用1％的卡因行粘膜表面麻醉。53例采用瓦合粘膜瓣法，3例用瓦合粘膜瓣联合阴道粘膜瓣修复法。结果：56例术后一月随访，53例处女膜孔径为一指，成功率94．64％。结论：采用1％的卡因粘膜表面麻醉，瓦合粘膜瓣法及瓦合粘膜联合阴道粘膜瓣修复法对处女膜修复是行之有效的。     

激光上皮下角膜磨镶术后角膜上皮瓣临床观察

目的 观察及探讨准分子激光上皮下角膜磨镶术(Laser subepithel ialkeratomileusis，LASEK)后，角膜上皮瓣的成活率及其影响因素。方法 对行LASEK治疗的42例(80眼)于术后1、2、3天，1、2、3、4周在裂隙灯显微镜下进行角膜上皮瓣的观察。结果 34例(68眼)，角膜上皮瓣成活，成活占85％(68／80)；未成活8例(12眼)，未成活占15％(12／80)。结论 LASEK术后角膜上皮瓣成活率的高低，决定着LASEK的临床疗效，影响其成活的因素是多方面的。其中角膜上皮瓣边缘不整齐、破裂、对位不良、操作时间过长可能是其主要原因。     

扇形额肌筋膜瓣悬吊治疗上睑下垂

目的：探计上睑下垂的较好治疗方法，以改进治疗效果方法：设计井应用扇形额肌筋膜瓣悬吊治疗上睑下垂，结果应用本方击治疗上睑下垂83倒，126只眼，致采满意。其中43例经3个月-10年随访，除3例(4只眼)下垂复发外，其余均取得了良好效果，未见其他并发症发生。结论：本方法的主要特点是扇形筋膜瓣有丰富的血供，并且能均衡覆盖在睑板上以充分上提上睑，符合生理和解音4的要求。     

Recurrent venous thrombosis following free flap surgery: The role of heparin-induced thrombocytopenia

Complications following free tissue transfer have been well established in the literature. Common and rare causes of free flap failure must be addressed by the treating surgeon when microvascular patency is threatened. With the evolution and prevalence of microsurgery, ‘rare’ causes of free flap failure will become increasingly frequent. A high index of suspicion must be established in patients with multiple failed operative interventions. A case of recurrent free flap failure secondary to heparin-induced thrombocytopenia is presented in a patient with a history of squamous cell carcinoma of the floor of the mouth, and a long-standing history of alcohol and tobacco consumption.     

Plastic surgical treatment of a chronic thoracic duct fistula using a sternocleidomastoid muscle flap — a case report

Thoracic duct fistula is a rare but potentially serious complication of head and neck surgery. Such fistulae may be difficult to treat, and several techniques, both operative and non-operative, have been advocated. A case of successful surgical treatment of a chronic thoracic duct fistula is presented. The fistula occurred in a 51-year-old female following treatment of a solitary supraclavicular breast metastasis by local excision and radiotherapy. The divided duct was ligated and the area was covered with the clavicular head of the sternocleidomastoid muscle.     

The rhomboid flap for pilonidal disease

Introduction There have been many surgical techniques described for the treatment of pilonidal sinuses. Recurrent disease causes significant morbidity particularly with time from work. Aim To assess the rhomboid flap's role in promoting one‐stage primary healing in pilonidal disease and to evaluate the morbidity and recurrence. Methods Fifty‐three patients were prospectively recruited of which 27 had previous multiple abscess formation requiring surgical drainage from their pilonidal disease, although none had acute disease at the time of surgery. By using the transposition flap, we were able to obliterate the natal cleft and therefore the rolling action of the buttocks between the cleft in these patients and thereby remove one of the factors involved in pilonidal disease. Hospital stay, healing time, wound infection, wound breakdown and recurrence were noted. Results There were 47 males and 6 females with a median age of 28 years (range 16–64 years). Median follow‐up was 24 months (range 3–36 months). Post‐operative morbidity involved superficial wound infection in 7 (13%) which settled with out‐patient dressings. There were four recurrences (7%), two occurred between the flap and the anal canal, and the other two in the flap margin needing intervention. All the patients healed their wounds and the median healing time was 14 days. Conclusion As this condition affects a predominantly young population causing significant time off from work, we feel that the Rhomboid Flap is useful for difficult cases in that it allows early return to full activity and does not necessitate prolonged postoperative care.     

头皮缺损颅骨外露的修复

我科1980～1991年收治外伤性或颅面部肿瘤切除后头皮缺损颅骨外露9例,分别应用吻合血管的游离大网膜结合中厚皮片移植、游离皮瓣或轴型皮瓣转位结合皮片移植修复。讨论了修复时机、修复方法以及手术注意事项。认为双侧股前外侧游离皮瓣是修复全头皮缺损颅骨外露的可取方法,而吻合血管的游离大网膜移植修复颅骨外露的方法应尽量避免。
