Minimally Invasive Neck Dissection (MIND) Using Standard Laparoscopic Equipment: a Preliminary Report and Description of Technique.

Neck dissection leaves behind an aesthetically unacceptable scar over front of the neck. Various techniques, both endoscopic and robotic, have been tried to avoid this scar. Though comparatively more cases of robotic surgery are reported than endoscopic neck dissection, the cost and availability of robot precludes many patients from getting the benefit of minimally invasive neck dissection (MIND). We performed minimally invasive neck dissection for two carefully selected patients with early oral cancer and cN0. We used standard endoscopic equipment and ubiquitously available laparoscopic ports. We used gas insufflation to create the working space. Our results show that MIND is feasible and oncologically safe. The scars produced are aesthetically better than that of conventional open neck dissection. This procedure leaves no scars in the anterior aspect of the neck. This technique can be replicated at any center with endoscopic equipments without need for purchasing specialised retractors or a robot.

Reconstructive Indications of Anterolateral Thigh Free Flaps in Head and Neck Reconstruction.

Anterolateral thigh (ALT) free flap is a common flap with multitude of indications. The purpose of this article is to review the reconstructive indications of the flap in head and neck defects. This is a retrospective study of 194 consecutive ALT flaps. Data including patient characteristics (age, sex, comorbidities), disease characteristics (histology, T stage), and flap characteristics (size of the flap, type of closure of ALT donor site) were collected. The outcome in terms of flap success rate, surgical, and donor site morbidity were studied. A total of 194 flaps were performed in 193 patients over a period of 10 years. Mean age of the patients was 55 years (range 16-80 years). Out of the 193 patients, 91 (47.1%) patients had oromandibular defects, 52 (26.9%) had tongue defects, 15 (7.7%) had pharyngeal defects, 17 (8.8%) had skull base defects, 4 (2%) had scalp defects, and 14 (7.2%) had contour defects of the neck. The overall flap success rate was 95.8% (8 total flap loss out of 194). Hypertrophic scar was the commonest donor site problem seen in 20 (10.3%) patients. This study shows the versatility of free ALT flap in head and neck reconstruction. It is a reliable and safe. Donor site morbidity is minimal.

Safety and efficacy of low molecular weight dextran (dextran 40) in head and neck free flap reconstruction.

BACKGROUND: Antithrombotic agents have been used in microvascular surgeries. Low molecular weight dextran (dextran 40), though used, is not without complications. METHODS: Retrospective analysis of 172 consecutive flaps. A comparison was made between two groups of patients (86 flaps each) with and without the use of dextran 40, in terms of safety and efficacy. RESULTS: The free flap survival rate was 95.9%. The flap survival rates were comparable between the groups. Total flap loss in Group A (patients who received dextran 40) was 3.5% compared with 2.3% in Group B (patients who did not receive dextran 40) (p = 1.00). There was no statistically significant difference in the incidence of thrombotic flap complications between the groups. None of the patients developed acute respiratory distress syndrome or required prolonged ventilator support. No patient had dextran-related anaphylactoid reactions. Thirty-eight patients (43.7%) in Group A had postoperative atelectasis and 21 (25.6%) patients in Group B had this complication (p = 0.01). Six patients in Group A developed postoperative pneumonia, and five patients in Group B developed this complication (p = 0.93). CONCLUSIONS: Though dextran 40 did not result in any significant adverse local or systemic complications, it is not useful as a postoperative antithrombotic agent in head and neck oncologic reconstruction with free tissue transfer.

Cricotracheal reconstruction with free radial forearm flap and titanium mesh.

BACKGROUND: Reconstruction after partial cricotracheal resection is technically demanding and is seldom reported in literature. The purpose of this study was to report a technique of reconstruction of such a defect with a radial forearm flap supported by a titanium mesh. METHODS: A 75-year-old man who was diagnosed with a case of papillary carcinoma thyroid, underwent excision of the tumor with a partial cricotracheal resection. The defect was reconstructed with a free radial forearm flap with fascia suspended on a titanium mesh. RESULTS: At a follow-up of 6 months after treatment, the patient has normal nasal breathing and an acceptable voice. CONCLUSION: This reconstructive technique enabled us to maintain the integrity of the subglottic airway. Our technique was unique in that we used the skin-lined part of the radial forearm flap to line the airway and the fascia to cover the titanium mesh outside, thereby preventing plate exposure.

Short-term augmentation of venous drainage with extra-corporeal shunt and simultaneous auto-transfusion, for salvaging a congested free flap.

Adequate drainage of venous blood is the most critical part of successful free tissue transfer. We report a case of anterolateral thigh flap used for covering open communited tibial fracture. The flap was salvaged with short term augmentation of venous drainage with external shunt. The drainage was continued for six days. It was confirmed that there is no more congestion after blocking the catheter and then the drainage was discontinued on seventh day. The flap was successfully salvaged. This method has potential applications in multiple situations for successful salvage of free tissue transfer.
