Application of a modified paramedian lower lip-submandibular approach in maxillary (subtotal) total resection / 华西口腔医学杂志

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of a modified paramedian lower lip-submandibular approach for maxillary (subtotal) total resection.@*METHODS@#Eleven patients of maxillary tumors underwent maxillary (subtotal) total resection through the modified paramedian lower lip-submandibular approach. Clinical follow-up visits were conducted to evaluate appearance restoration, facial nerve functional status, parotid gland functional status, and orbital region complication.@*RESULTS@#During the follow-up period of 6-36 months, the appearance of all 11 patients recovered well. All cases presented hidden scars. No facial nerve and parotid duct injury, lower eyelid edema, lower eyelid ectropion, or epiphora in all cases was observed.@*CONCLUSIONS@#Applying modified paramedian lower lip-submandibular approach to maxillary (subtotal) total resection effectively reduces incidence of orbital region complications including lower eyelid edema, lower eyelid ectropion, and epiphora, which often occur to traditional approach. The modified approach produces more subtle scars than other methods and should be applied to treatment of maxillary (subtotal) total resection.
