ABSTRACT
Oral submucous fibrosis [OSF] is a premalignant condition characterized by inflammation and progressive fibrosis of submucosal tissue, resulting in trismus. It is associated with chewing of areca nut in betel quid. Mortality rate is significant because it transforms into oral squamous cell carcinoma at a rate of 2.3%–7.6%. The aim of this article is to share our experience in managing a case of recurrent oral submucous fibrosis with nil mouth opening by surgical excision, coronoidotomy, and reconstruction of buccal defect using bilateral inferiorly based nasolabial flap, followed by active oral physiotherapy. The patient had reached an acceptable mouth opening with no further recurrence. The patient was observed closely for any malignant transformation. Surgical excision of bands and coronoidotomy followed by reconstruction with nasolabial flaps and active physiotherapy in the postoperative period remains a good option for recurrent and advanced cases of OSF with acceptable functional and cosmetic results.
ABSTRACT
Objective To investigate the methods and effects of nasolabial flaps for repair of defects after skin tumor removal on midface.Methods From Augest 2012 to March 2015,the different flaps from nasolabial fold were utilized to repair 22 skin defects due to surgical removal of skin tumors on midface.There were 12 flaps with subcutaneous pedicle and 10 flaps with skin pedicle in the group.The size of the defects ranged from0.5cm × 1.0cmto4.0cm × 5.0cm.Results After operation,all flaps survived with primary healing,cosmetic results were satisfactory with conceal scar and no facial organs distortion after 1 month to 2 years following-up.No tumor recurrence occurred.Conclusions Thenasolabial flaps with appropriate pedicles could obtain the satisfactory results for the reconstruction of medium-sized skin defects on midface,especially suitable for middle-aged and elderly patients.
