Abstract:

Introduction: The inferiorly and laterally based platysma myocutaneous flap contains hair in some ethnics; therefore, it is required to change the myocutaneous flap to myofascial flap to prevent the hair growth after its transfer to the oral cavity.   Materials and Methods: Five male mongrel dogs were selected for this study. De-epithelialized laterally based platysma flap, muscle part facing the oral cavity, was used for buccal reconstruction. The clinical healing process was photographed every week. After 40 days, biopsy specimens were obtained from the transferred flap.   Results: According to the results, all flaps survived. At the end of the first week, the flap was covered with fibrinous exudate. On the third week, only the center of the transferred flap was not covered with mucosa. Within 40 days, the flap was distinguishable clinically from the adjacent buccal mucosa just by hypopigmentation. Hematoxylin and eosin staining of the biopsy specimens taken on day 40 showed thin stratified squamous epithelium covered with a tiny parakeratin layer.   Conclusion: Myofascial platysma flap, muscle part faced oral cavity, survives and undergoes mucosalization after adaptation to the recipient oral tissue.

Vertical platysma myocutaneous flap reconstruction for T2-staged oral carcinoma.

The surgical resection of tumour-affected oral soft tissue structures often leads to tissue defects. Various techniques can be used for reconstruction. Our experience of using a vertical platysma myocutaneous flap in a group of patients who underwent reconstruction after T2-staged oral cancer surgical resection associated with neck dissection is described. Only one patient required a surgical r...

Oral cavity reconstruction with the masseter flap

The purpose of this report is to highlight how an unusual, outdated, unpopular and overlooked reconstructive method such as the masseter flap can be a reliable, straightforward and effective solution for oral reconstruction in selected cases. We report the transposition of the masseter crossover flap in two previously pre-treated patients presenting a second primary oral squamous cell carcinoma...

[Buccal flap in reconstruction of mucosal defects in oral cavity].

INTRODUCTION The buccal flaps are an effective alternative in treatment patients with small defects of the oral cavity due to: the small size of the flap, the lack of donor site, less risk of postoperative complications and short procedure time. MATERIAL AND METHODS In the Department of Otolaryngology and Laryngological Oncology in Poznan in the years 2005-2008 was performed 7 resections of o...

Laryngeal reconstruction by platysma myofascial flap after vertical partial laryngectomy.

BACKGROUND Many methods of glottic reconstruction have been described for patients undergoing vertical partial laryngectomy to reestablish the glottic integrity. METHODS Fifteen patients with T2 squamous cell carcinoma of the glottis were included in this prospective clinical trial. All patients were treated by vertical partial laryngectomy with laryngeal reconstruction by platysma myofascial...

Myodermal flap for reconstruction of oral mucosa.

Purpose Myocutaneous flaps were commonly used to repair the mucosal defect that results from ablative tumor surgery. However, skin is not a perfect substitute for the oral mucosa because it can lead to poor hygiene due to hair growth and desquamation. The myodermal flaps used for the reconstruction of mucosa in oncologic surgery of the oral cavity. Material and method Pectoralis major and platy...
