Pharyngostoma reconstruction after laryngectomy and radiotherapy: A retrospective study and literature review.

BACKGROUND: The occurrence of pharyngocutaneous fistula or pharyngostoma after oncologic head and neck surgery is a serious complication. It is the most common complication after major hypopharyngeal and laryngeal ablative surgery. AIM: The purpose of this study is to review the surgical approach and evaluate the results regarding reconstruction methods of pharyngostoma, caused after laryngectomy and radiotherapy. PATIENTS AND METHODS: The total number of patients is 15. Pharyngostoma caused swallowing difficulties, as well as frequent aspiration pneumonia. The intervention interval from laryngectomy to pharyngeal reconstruction varied between one and three years, depending on the severity of symptoms and after the complete failure of conservative rehabilitation methods. Pharyngostoma reconstruction was performed mainly with pectoralis major myocutaneous flap in 11 cases. The radial forearm free flap and the anterolateral thigh free flap were also used in the remaining four cases. RESULTS: The post-operative course was uncomplicated, and in most cases, the feeding with soft food started after a barium meal between 15 and 20 days post-operatively. Complications include wound dehiscence and leak treated conservatively and one case of carotid rupture. CONCLUSIONS: The gold standard for pharyngostoma reconstruction, after laryngectomy and cervical radiotherapy, remains the use of pectoralis major myocutaneous flap. In cases of extensive neck radionecrosis, free flaps are preferable. Reliable and stable cover of the large vessels of the neck, along with the reconstruction of the digestive tract and the restoration of swallowing function are issues that are analysed in correlation with the avoidance of stenosis and swallowing difficulties.

Hemifacial Microsomia Surgical Approach and Anotia Reconstruction: A Case Report.

BACKGROUND/AIM: Hemifacial microsomia (HFM) is the second most common congenital anomaly of the craniomaxillofacial region after the cleft lip and palate. This malformation is characterized by unilateral mandible and ear hypoplasia. Treatment varies and depends on different phenotypes. Severe deficiencies require multiple reconstructive surgeries to address facial asymmetries. This study aimed to review the surgical approach and evaluate the postoperative results of a case with right hemifacial microsomia and anotia. CASE REPORT: This is the case of a 35-year-old female patient who, after multiple graft operations in the right mandible due to hemifacial microsomia, was operated for auricle reconstruction. Initially, a three-dimensional custom made Medpor (porex) was used, covered by the superficial temporal fascia. Subsequently, due to inflammation and partial exposure of this porous polyethylene implant (PPI), a temporalis muscular flap along with the deep temporal fascia were used as a salvage operation. Ten months later, the patient underwent deep plane face lift combined with open rhinoplasty. Lefort I osteotomies and transoral lip lengthening through a transection of the levator nasi septi muscle were also performed. Ear helix reconstruction was completed with a rotation scalp flap after tissue expansion. The patient had an uncomplicated postoperative course with an aesthetically acceptable result. CONCLUSION: As a congenital disorder, hemifacial microsomia is present at birth and successful reconstruction is of fundamental importance for the smooth integration of these individuals into society. The multiple asymmetries, the affected topographic area of the face, as well as the onset in neonatal age constitute a challenge for reconstructive surgery.

Tumor ablation including carotid artery resection and simultaneous reconstruction: A retrospective study.

The study purpose is to review the surgical approach and evaluate the results in cases of head and neck malignancies with internal carotid artery invasion. The anatomical site of the primary tumor varied including a fixed massive metastatic neck disease of an occult intraoral carcinoma of the right tonsil, a recurrent metastatic neck tumor after laryngectomy for glottic primary carcinoma and a metastatic malignant melanoma of an unknown primary origin. In all cases carotid artery was invaded and therefore resected. An extended Javid shunt was performed between common carotid artery (CCA) and internal carotid artery (ICA) followed by CCA grafting with an interposition saphenous vein graft. In one case the vagus nerve was also grafted with an interposition sural graft. The total patient number was three. By clinical examination, follow-up and duplex scanning, the patency of the carotid grafts, vascular and non-vascular complications, disease recurrence and survival were analysed. Additionally, there was a double metachronous reconstruction for recurrence, giving the opportunity to study the graft adoption and response to disease. Internal carotid artery invasion portends a poor prognosis. The results show that carotid artery resection followed by the appropriate reconstruction yields a chance for cure or can provide reasonable palliation.

Management of head & neck sarcomas in adults: A retrospective study.

The research purpose is to review the surgical approach and evaluate the results in adult patients with head and neck sarcomas. The histopathology varied, including two leiomyosarcomas, six malignant fibrous histiocytomas, two malignant peripheral nerve sheath tumors, four dermatofibrosarcomas protuberans, three osteosarcomas, two angiosarcomas, one liposarcoma, one Ewing sarcoma, one synovial sarcoma, two unclassified/non-differentiated sarcomas and one solitary fibrous tumor. Surgical resection included maxillectomy, mandibulectomy, craniectomy, parotidectomy, scalp resection, face skin resection and laminectomy. The reconstruction was performed with one rectus abdominis flap, four radial forearm flaps, two latissimus dorsi flaps, two vascularized fibula flaps, two pectoralis major myocutaneous flaps, two trapezius flaps, two temporalis flaps, seven scalp flaps and two nasolabial flaps. The total patient number was 24. The hospitalization was uncomplicated, followed by postoperative radiotherapy in the majority of cases. In a mean 15-year follow-up period, 11 patients are still alive and disease-free. There were four recurrences treated with palliative radiotherapy. The surgical approach for head and neck sarcomas, including the achievement of a functionally acceptable result by organ sparing techniques, remains challenging. Wide resection combined with the appropriate reconstruction, particularly with microsurgical techniques, and followed by adjuvant radiotherapy or chemotherapy offer improved prognosis and quality of life.

Midface microvascular reconstruction after maxillary complex tumor resection: A retrospective study.

The study purpose is to review the surgical approach and evaluate the results in managing patients with advanced midface and maxillary complex tumors. The most common anatomical site of the primary tumor was the maxilla, sometimes with extension to the orbit and anterior fossa, parotid and middle ear or even the lip. Surgical resection included maxillectomy in the majority of cases, combined with orbital exenteration or orbitectomy and anterior fossa resection. Parotidectomy and mastoidectomy/core petrosectomy were also performed. Reconstruction was performed with radial forearm osteocutaneous free flap, latissimus dorsi myocutaneous flap with scapular bone flap, lengthening temporalis myoplasty, rectus abdominis free flap, anterolateral thigh flap, in combination with temporalis and vastus lateralis, as well as pectoralis major myocutaneous flap. A total of 36 midface tumor excisions were performed, followed by the appropriate reconstruction. The average follow-up period was 15 years. To date, 23 patients are disease free, while 6 patients presented disease recurrence and 7 patients died during the 15-year follow-up period. Surgical resection remains the gold standard for midface tumors management. When safely performed, combined with microvascular and dynamic face reconstruction, surgery can offer improvement in quality of life and prolong the overall survival.
