“…This manipulation may have led to poor performance in the FTTC group at 250 Hz. The tensor tympani tendon cut did not affect hearing at 0.5 Hz-4 kHz after tympanoplasty, 15 but tensor tympani tendon contraction is related to low-frequency hearing loss. 16 In addition, barred cartilage, which might result in decreased tension of drum, was placed under the malleus, which may be responsible for the poor performance at 4000 Hz in the FTTC group in their study.…”

Objective: Hearing performance after myringoplasty with full-thickness tragal cartilage (FTTC) has been questioned because a considerable difference exists between the graft and natural tympanum. This study aimed to analyze the air-bone gap (ABG) trends before and after myringoplasty and its interaction with risk factors in the FTTC group; further, it compared postoperative ABG in the FTTC group to that in the temporalis fascia (TF) and partial-thickness tragal cartilage (PTTC) groups. Design: A retrospective cohort study Setting: Tertiary care University Hospital Methods: The general linear model repeated measures was used to analyze ABG trends in the FTTC group and its influencing factors. Non-parametric tests were used to compare ABGs in the FTTC group and the other two groups. Propensity score matching was done to balance baseline characteristics between the TF and FTTC group. Results: The mean postoperative ABG in the FTTC group was 12.17±6.58 dB, and 90.9% of the patients had a mean ABG within 20 dB, which improved significantly after surgery (F(1,108)=38.707, P<.001). The tympanic perforation size and malleus handle exposure status, which significantly affected the preoperative ABG, did not affect postoperative hearing (P>.05). In the FTTC group, the mean ABG was comparable to that in the other two groups (P>.05). For all except 250 Hz, a similar audiological performance was observed in the FTTC and PTTC groups; FTTC had a better performance at 250 Hz (Z=-2.277, P=.023). Conclusions: Good hearing performance was achieved after myringoplasty with FTTC, irrespective of the preoperative perforation size and malleus handle exposure status.

“…According to Todd [ 5 ], orientation of manubrium is inexplicably widely variable. Deng et al [ 6 ] have concluded that the section of the tensor tympani muscle tendon in canal wall-down tympanoplasty with ossiculoplasty had no statistically significant influence on sound transmission and can be a safe maneuver in middle ear surgery.…”

The current study aims at observing effects of sacrificing the tensor tympani tendon when manubrium of malleus is foreshortened or retracted on graft uptake, hearing improvement, and occurrence of complications if any during type I tympanoplasty surgery for central perforations. 42 patients were included in group A where the tensor tendon was sectioned and 42 patients were included in group B where the tensor tympani tendon was retained and kept intact. Graft uptake rates are very good in both groups but hearing improvement was found significantly better in group A than group B. No unusual or undesired complications were seen in any of the cases. Sectioning of tensor tympani tendon is safe and effective procedure in cases where manubrium is foreshortened.
