Postoperative malodorous smell in open septorhinoplasty: the effect of intradomal suturing with mucosal release

The aim of this study was to test a mucosal release method for decreasing the occurrence of malodourous smells after septorhinoplasty by preventing formation of debris pockets after surgery.

This study included 50 adult patients from 18 to 45 years of age who underwent open septorhinoplasty from January to May 2019. Patients were divided into two groups. The first group had intradomal (transdomal) sutures without submucosal release, while the second group had mucosal release. All patients had scheduled post-op visits at 1, 2, 4, and 8 weeks and 6 months.

The overall postoperative rate of malodorous smell in both mucosal release and non-mucosal release patients at 2 weeks, 8 weeks and 6 months was 43.1%, 31.4% and 5.9%, respectively. Patients 36-45 years of age had a higher rate of postoperative malodorous smell with 55.6% at 2 weeks, decreasing to 33.3% at 8 weeks, and to less than 1% at 6 months. At 2 weeks after surgery, only 20% of the mucosal release group reported a malodorous smell compared to 65.4% in the non-mucosal release group. The rate was 8% at 8 weeks, and less than 1% at 6 months in the mucosal release group compared to 53.8% at 8 weeks and 11.5% at 6 months in the non-mucosal release group.

Utilizing absorbable polydioxanone sutures and releasing the vestibular mucosa of the LLC significantly reduced the rate of postoperative malodorous smell for septorhinoplasty patients with intradomal (transdomal) single-dome suturing.
