ABSTRACT
Objective@#To evaluate the usefulness of retroauricular hairline incision (RAHI) in partial superficial parotidectomy (PSP) by comparison with modified Blair incision (MBI).@*Methods@#A retrospective analysis of 64 medical records for patients with benign parotid tumors who underwent partial superficial parotidectomy was undertaken (28 were in MBI group, 36 in RAHI group). Size and location of tumors, operative time, occurrence of facial nerve paralysis and Frey′s syndrome, and cosmetic outcomes were compared between RAHI and MBI groups.@*Results@#Compared with MBI group, RAHI group showed better cosmetic results for benign parotid tumors in mean satisfaction score(P<0.001). There were no significant differences in size and location of tumors, operative time, incidence of transient or permanent facial nerve paralysis and Frey′s syndrome between two groups (P>0.05).@*Conclusions@#Partial superficial parotidectomy can be performed safely via RAHI in most cases of benign parotid tumors. Compared with MBI, RAHI for benign parotid tumorscan improve the cosmetic outcome, without increasing the operative time or operative morbidity.
ABSTRACT
BACKGROUND: Methods to effectively overcome re-stenosis or atresia following reconstruction of external auditory canal are explored.OBJECTIVE: To explore the effect of NiTi shape memory alloy netlike bracket to prevent the restenosis or atresia of newly constructed external ear canal in external canal atresia surgery. DESIGN, TIME AND SETTING: Case analysis of aural atresia patients from Department of Otorhinolaryngology Head and Neck Surgery, Third Hospital of Sun Yat-sen University was performed from January 2001 to June 2003. PARTICIPANTS: Eight cases of aural atresia were selected, including 5 patients with congenital aural atresia, and 3 with postnatal aural atresia. All cases had different degrees of conductive hearing loss. METHODS: All cases underwent external canals reconstruction by using NiTi shape memory alloy netlike brackets. MAIN OUTCOME MEASURES: Diameter of newly constructed aural canal and pure tone auditory threshold. RESULTS: All the eight ears had a smooth and wide external ear canal during follow up. No restenosis of canal or cicatricial contracture was found. Pure tone auditory threshold of 7 ears had improved postoperatively. CONCLUSION: NiTi shape memory alloy netlike bracket has definite effect to prevent the restenosis or atresia of new constructed external ear canal.
