Reconstruction of intraoral mucosal defects following tumor ablative surgery can be a challenging problem. The objective of this study was to evaluate the use of the palatal island mucoperiosteal flap (PIMPF) in reconstructing intraoral defects resulting from ablative tumor resections. The study included eight consecutive patients who underwent primary reconstruction using the PIMPF following intraoral tumor resections in a 5-year period by a single surgeon at a tertiary referral institute. Patients included five men and three women ranging in age from 32 to 69 years. Four patients were smokers (averaging 40 pack-years). None had received prior irradiation therapy. Resultant surgical defects ranged in size from 6 to 16.5 cm (mean 12.3 ± 3.9) and included areas of soft/hard palate, lateral pharyngeal wall, retromolar trigone and inner cheek. Final pathological findings revealed three benign and five malignant tumors, mostly from minor salivary gland origin. All patients began oral diet between postoperative days 1 and 4 (mean 2 days). All flaps survived well with good postoperative wound healing except one minor flap dehiscence that eventually healed by granulation tissue with no further surgery needed. All donor sites were completely healed by remucosalization within 5-13 weeks. No patients manifested permanent velopharyngeal insufficiency, speech impairment, or airway compromise after a follow-up period ranging from 13 to 56 months (mean 31.3 ± 15.9). The PIMPF was found to be an attractive single-staged versatile and reliable reconstructive option for postero-lateral oral cavity/oropharyngeal defects that provides well-vascularized, sensate mucosa with minimal morbidity.

    Many methods of cleft palate repair have been described. Two effective methods are commonly used for repair of soft palate clefts: the Wardill-Kilner V-Y push back and the Furlow double opposing Z-plasty; each has advantages and disadvantages. The aim of this study was to compare between the V-Y...
