Numerous methods for meatoplasty and conchoplasty have been introduced, but no clear V/S(the meatal cavity volume to the cross-sectional) was given and many patients have complained about poor cosmesis on follow-up. To explore the proper size, and cosmetic shape of the external auditory meatus and auditory canal for canal wall-down tympnomastoidectomy (CWD). In this observational case series study 36 patients undergone CWD with C-conchoplasty that uses a C-shape skin incision on the concha were reviewed. S and V/S of the preoperative, postoperative and contralateral normal ears were observed. We analyzed the relationship between the epithelialization time and postoperative V/S. Long-term efficacy observation and the shape of the meatus after the operation were observed. C-conchoplasty could effectively enlarge S and reduce V/S. The postoperative V/S were closer to the normal ear than that if we didn't do C-conchoplasty. The greater difference of V/S between the post-operative ears and the contralateral normal ears, the longer the epithelialization time will be. C-conchoplasty produced an excellent cosmetic result. No other complications were noted. The C-conchoplasty, which is a novel and easy technique in CWD, offers good functional and excellent cosmetic results with minimal risk of complications.
