Effect of Preoperative Mastoid Ventilation on Tympanoplasty Success

Abstract

Purpose. This study was conducted with the aim of investigating the relationship between mastoid air cell volumes and graft success after tympanoplasty. Material and Methods. This study was performed retrospectively with patients undergoing type I tympanoplasty and antrostomy. A total of 57 patients (20–35.09% female and 37–64.91% male) with a mean age of 29.69 ± SD (range 12–56 years) were included in the study. The patients were invited for a control at the 1st, 3rd, and 12th months, and otoscopic examinations and audiometric tests were performed. The temporal bone computed tomography images were screened with the 4800 Dpi optic resolution scanner and transferred to the computer environment in JPG format in order to calculate the mastoid air cell volume, and the volumes were calculated using the Autocad 2007 program. Results. Although, the graft success was determined to be better in the well-ventilated group, no significant difference could be found between the groups in terms of graft success at the 1st, 3rd, and 12th months (P > 0.05). No statistically significant difference could be found between the three groups in terms of the preoperative and postoperative hearing gains (P > 0.05).

Effect of pre-operative mastoid pneumatisation on tympanoplasty success

“…Our study showed no significance difference between the two groups (well pneumatised group vs sclerotic mastoid group) in the graft uptake rate in tympanoplasty, although the well pneumatised group had a higher success rate. Our result agreed with Amer et al 5 (2017), Metin et al 6 (2014), Sethi et al 8 (2005), Toros et al 9 (2010) and Yegin et al 24 (2016). However, Mohan et al 7 (2015) found that graft uptake rate in cases of tubotympanic chronic suppurative otitis media was better and statistically significant in well pneumatised mastoids when compared with sclerotic mastoids.…”

“…8 Also, according to Metin et al , there was no statistically significant difference between the well and poorly pneumatised groups in terms of audiometry results after one year of follow up. 6…”

“…In terms of ABG change, there was no significant difference between the well pneumatised group and the sclerotic mastoid group concerning ABG improvement in studies performed by Metin et al , Sethi et al and Toros et al . 6,8,9…”

Effects of mastoid and middle-ear volume on graft success and hearing outcomes in paediatric tympanoplasty

“…In contrast, Metin et al . 25 found no significant relationship between mastoid pneumatisation and graft success and hearing gain in patients undergoing type 1 tympanoplasty and antrostomy. Yegin et al .…”

“…Takahashi et al 24 showed that the lack of mastoid pneumatisation and Eustachian tube mechanical obstruction on high-resolution CT imaging negatively affected tympanoplasty results. In contrast, Metin et al 25 found no significant relationship between mastoid pneumatisation and graft success and hearing gain in patients undergoing type 1 tympanoplasty and antrostomy. Yegin et al 2 examined the effect of mastoid pneumatisation on graft success in type 1 tympanoplasty in adult patients and concluded that the degree of mastoid pneumatisation did not affect the operation's success.…”
