title: Donor site morbidity in buccinator-based myomucosal flaps: A retrospective study.
abstract: BACKGROUND
  Buccinator-based myomucosal flaps can be used as a lining in oral cavity, pharyngeal, esophageal, and nasal reconstructions. Donor site morbidity is an important factor in selecting a flap, therefore, it was decided that donor site morbidity of this type of flap should be evaluated.
  
  
  METHODS
  In a retrospective study, patients for whom this flap had been used for oral, nasal, or pharyngeal reconstruction in 2008-2012 were recalled. Donor site morbidity including reduction in maximal interincisal opening (MIO), obliteration of the mandibular vestibule, injury to the Stensen duct, and vertical fibrous band in buccal mucosa were evaluated.
  
  
  RESULTS
  Twenty-two buccinator-based myomucosal flaps (20 patients) had been used for oral, nasal, or oropharyngeal reconstruction. The most common flap used was the Facial Artery Musculomucosal (FAMM) flap (50%), and the commonest cause for flap use was the presence of a cleft lip/palate sequel in patients (45%). Four patients had developed complications (minimal reduction in MIO) related to the donor site.
  
  
  CONCLUSIONS
  Donor site morbidity associated with buccinator-based myomucosal flaps is low. However, minimal reduction of mouth opening occurred in 20% of the patients.
