A new lateral cervical approach for salvage total laryngo-pharyngectomy

Prevention of fistulas after salvage laryngectomy using temporoparietal fascia free flap

We conducted a retrospective review to assess the role of the temporoparietalis fascia flap (TPFF), comparing rates of postoperative pharyngocutaneous fistula (PCF) and functional outcomes with those of pectoralis major myocutaneous flap (PMMF) and primary closure of the pharynx, in a population of patients treated with salvage total laryngectomy (STL). Patients were divided in three groups depending on the pharynx reconstruction technique after primary closure: no vascularised tissue augmentation (group 1), PMMF patch (group 2), or TPFF patch (group 3). The main outcomes analysed were overall fistula rate, fistula requiring reoperation and speech and swallowing function at 6 months. Factors influencing the incidence of fistulas were also evaluated. 39 patients respected inclusion criteria: 14, 11 and 14 patients in the three groups, respectively. Nine patients of 39 (23.1%) experienced a PCF. No statistically significant differences were noted between the three groups, except for a longer surgical operation time and a trend for better functional results in group 3. None of the factors analysed significantly influenced the overall rate of fistula. TPFF patch thus represents a reliable alternative to PMMF in preventing PCF in the setting of STL, with minor donor-site morbidity and good functional outcomes.

Lateral conservative approach for recurrent/persistent hypopharyngeal carcinoma: a case series

PURPOSE

Early persistent/recurrent hypopharyngeal tumours represent a challenge for surgeons who have to balance the need for oncological radicality and the desire to maintain a functioning larynx with preservation of the patient's quality of life. The aim of this study was primarily to understand the technical feasibility, functional outcomes, and the possibility of obtaining oncological radicality using lateral hypopharyngectomy with laryngeal preservation in early recurrent post-radio/(chemo)therapy hypopharyngeal tumours.

METHODS

Patients with recurrent T1 hypopharyngeal squamous cell carcinoma were retrospectively selected from our institutional database. The external lateral approach according to Spriano and a modified lateral hypopharyngectomy with laryngeal preservation were used to resect tumours of the lateral pyriform sinus wall. Reconstruction was obtained by direct approximation of the posterior border of the sectioned thyroid cartilage to the posterior hypopharyngeal wall, and this was reinforced with a second layer of vascularised and non-irradiated tissue that was provided by a microvascular fascial anterobrachial flap. Swallowing was assessed 3 weeks after surgery using videoendoscopic evaluation.

RESULTS

The surgical procedure was technically feasible, and complete resection was obtained in all patients. None of the patients experienced major post-operative complications (salivary fistula, bleeding, aspiration pneumonia). Mild dysphagia was observed in one patient who underwent swallowing rehabilitation. Tracheostomy was closed in all patients. No recurrence was recorded after a median follow-up of 20 months.

CONCLUSION

The reported experience shows that, in selected cases, it is possible to radically remove lateral hypopharyngeal cancer with acceptable functional results.

Lateral cervical approach for salvage total laryngectomy without pharyngeal reinforcement with pedicled or free flaps: our preliminary experience in six patients

PURPOSE

To analyze the surgical outcomes in terms of postoperative wound complications in a small case series of six patients treated with lateral cervical approach (LCA) for salvage total laryngectomy (STL) without prophylactic use of the pectoralis major myocutaneous flap (PMMF) or free flaps.

METHODS

Between September 2018 and August 2019, six patients with recurrent/residual squamous-cell carcinoma after (chemo)radiotherapy [(C)RT] underwent STL with minimally invasive LCA with the anterior myocutaneous flap (AMCF), sparing the prelaryngeal tissue. Clinical records were retrospectively reviewed.

RESULTS

Wound dehiscence and local complications were prevented in five cases. Pharyngocutaneous fistula (PCF) occurred in one case and the closure was achieved by medical dressing with spontaneous healing within 15 days. Oral intake of liquids started 2 weeks after surgery in the five patients without local complications, after 24 days in the patient with PCF.

CONCLUSION

STL through the LCA after [(C)RT] failure seems to be feasible and effective in terms of prevention of local complications as wound dehiscence and fistula. More large clinical series are needed to confirm whether the use of LCA reduced the rate of postoperative wound complications following STL without the prophylactic use of pedicled or free flaps.
