  • Galeal pedicle flap of the occipital region for Pharynx Reconstruction: anatomic and clinical considerations.
    Plastic and reconstructive surgery, 1998
    Co-Authors: R. P. De Magalhaes, Lenine Garcia Brandão, Marina Helena Cury Gallottini Magalhães, Alberto Rossetti Ferraz
    Abstract:

    Surgeons are still searching for the ideal method for Pharynx Reconstruction after tumor ablation. The objective of this study was to prove the anatomic and clinical viability of an occipital galeal pedicle flap for hypoPharynx Reconstruction. We studied anatomic details in 50 fresh adult cadavers. The dissections were performed after posterior galea exposure, silicone injection in occipital vessels, and mobilization of the galeal flap with an 8 x 8 cm square of galea. We also used the proposed flap in three clinical cases after laryngopharyngectomy. The surgical technique and its problems are described. Some of the anatomic data obtained are as follows: occipital artery diameter, 2.69 mm (mean); occipital artery length, 134.25 mm; area of occipital vessels network on galea, 148.77 cm2; pedicle length, 116.63 mm; and success in rotation to Pharynx region (100 percent). The flap showed good functional and cosmetic results when used in three patients. A partial necrosis occurred in one case. The pedicled galeal occipital flap has favorable anatomic characteristics for use in head and neck Reconstruction. Additional studies are necessary to provide more substantial information about its clinical viability.

  • Galeal flap based on superficial temporal vessels for oral cavity and Pharynx Reconstruction: an anatomical study
    Clinics (Sao Paulo Brazil), 2008
    Co-Authors: Fábio Roberto Pinto, Lenine Garcia Brandão, Roberto P. Magalhães, Marcelo Doria Durazzo, Aldo Junqueira Rodrigues
    Abstract:

    PURPOSE: Despite the advances in microvascular free tissue transfer for intraoral Reconstruction, this surgery is not recommended for all patients. In specific cases, the pedicled temporoparietal galeal flap may be an option for reconstructive procedures in the head and neck regions. The objective of this paper is to present the anatomical aspects of a galeal flap based on the superficial temporal vessels and to test its potential for reconstructing diverse sites of the oral cavity and Pharynx. METHODS: We performed 40 dissections on 34 fresh adult cadavers. The flap vascular anatomy was studied by injecting latex into the superficial temporal vessels. A standardized square-shape flap measuring 10 x 10 cm2, pedicled on the superficial temporal vessels, was raised. Oral cavity and oroPharynx Reconstruction simulations were performed after flap transposition into the mouth by passing it under the zygomatic arch. Hypopharyngeal Reconstruction was tested by transposing the flap to the neck under the facial nerve. RESULTS: After latex injection, a rich vascular network over the temporoparietal galea was observed directly from the superficial temporal artery, and a well-vascularized flap based on this vessel was raised. In the Reconstruction simulations, the flap was shown to be suitable for the coverage of hypothetical defects in most oral cavity and pharyngeal sites, mainly the retromolar trigone, tonsil area, and buccal mucosa. CONCLUSIONS: A galeal flap based on the superficial temporal vessels presents favorable anatomical characteristics for oral cavity and pharyngeal Reconstruction.

  • Neurologic late effects associated with radiologic evidence of vertebral osteoradionecrosis after salvage laryngectomy: A syndrome associated with survivors of laryngeal and hypopharyngeal cancer.
    Head & neck, 2016
    Co-Authors: Andrew J. Rosko, Matthew E. Spector, Garrett R. Griffin, Jeffrey M. Vainshtein, Jae Y. Lee, Carol R. Bradford, Mark E. Prince, Jeffrey S. Moyer, Francis P. Worden, Avraham Eisbruch
    Abstract:

    Background Delayed nonspecific posterior neck pain after pharyngeal instrumentation can be associated with a syndrome of rapidly progressive neurologic embarrassment. We present this cohort to help define the syndrome and aid in early detection. Methods We conducted a retrospective case series of 6 patients presenting from 2003 to 2012 with a history of laryngeal or hypopharyngeal squamous cell carcinoma (SCC) who underwent radiotherapy (RT) or chemoradiotherapy (CRT) followed by salvage laryngectomy. Results Posterior neck and upper back pain developed a mean of 27.5 days after instrumentation of the Pharynx (Reconstruction after laryngectomy or pharyngeal dilation). Myelopathy developed an average of 21.5 days after the onset of posterior neck pain. Five patients required urgent decompression. Three patients developed quadriplegia. The disease-specific mortality was 50%. Conclusion There is a syndrome of late neurological effects after RT, salvage surgery, and pharyngeal instrumentation that is associated with high morbidity and mortality. © 2015 Wiley Periodicals, Inc.
