Objective: The objective of this study was to report an original method of malleus relocation allowing for better placement of both partial and total prostheses in ossicular reconstruction.
Study Design: We conducted a retrospective review of clinical and audiometric findings.
Setting: A tertiary referral center.
Materials And Methods: This is a study of 268 patients who underwent ossiculoplasty surgery from October 1997 to October 2000 for chronic otitis media, noninflammatory disease, and otosclerosis revision. Malleus relocation with total and partial ossicular replacement prostheses was used in all cases. Audiometric assessment included pre- and postoperative audiometric evaluation using conventional audiometry. Air-bone gap, bone-conduction thresholds, and air-conduction thresholds were measured.
Results: A postoperative air-bone gap closed to within 10 dB was achieved in 56% of cases. An air-bone gap smaller than 20 dB was obtained in 78% of cases. Postoperative improvement of air-conduction thresholds superior to 20 dB was found in 41.5% of cases. The postoperative bone-conduction thresholds were unchanged in 98% of cases. One case of total postoperative sensorineural hearing loss was seen in this series (0.4%). Extrusion of the protheses was not observed in this series. Follow up ranged from 6 to 36 months (mean, 12.4 months).
Conclusion: This study shows that malleus relocation is a safe and efficient technique for ossicular reconstruction. The ideal position of the relocated malleus allows easier and more stable placement of middle ear prostheses.

Ossicular Reconstruction with TORP: Does Malleus has a Role?
Indian J Otolaryngol Head Neck Surg
December 2024
Sri Guru Ram Das University Of Health Sciences, House No.653 Block-I BRS Nagar, Ludhiana, Amritsar, Punjab India.
Article Synopsis
- - The study investigates the role of the malleus in hearing restoration through a prosthesis, comparing outcomes in patients where the malleus was preserved versus those where it was removed during ossiculoplasty.
- - It included 60 patients, showing significant hearing improvement in both groups post-surgery, with an emphasis on how the malleus affects auditory outcomes and implant stability.
- - Results indicated that while both groups achieved similar levels of post-operative hearing improvement, preserving the malleus (M +) led to a greater average reduction in air-bone gap compared to its removal (M-).
TORP Versus PORP in Austin Type A Ossicular Defects: Which is the Right Choice?
Indian J Otolaryngol Head Neck Surg
December 2024
Patiala, Punjab 147001 India.
Article Synopsis
- - Chronic ear diseases often lead to ossicular defects, requiring the use of ossicular reconstruction prostheses like TORP (total ossicular replacement prosthesis) and PORP (partial ossicular replacement prosthesis) to restore hearing continuity.
- - Research shows that using a malleus to footplate reconstruction yields better mechanical outcomes than malleus to stapes superstructure, but long-term effectiveness of TORP versus PORP remains unclear.
- - A study involving 60 patients with Austin type A defects found significant post-operative improvements in hearing for both TORP and PORP groups, with 90% of patients showing mild hearing loss after surgery compared to their pre-operative condition.
Manubrio-incudo-stapedioplasty for reconstruction of Austin-Kartush type B ossicular defects.
J Laryngol Otol
June 2019
Department of Otorhinolaryngology,Faculty of Medicine, Van Yüzüncü Yıl University,Van,Turkey.
Objective: Manubrio-incudo-stapedioplasty functional outcomes were compared to those of other methods for reconstructing Austin-Kartush type B ossicular defects.
Methods: Forty-two patients underwent Austin-Kartush type B ossicular defect reconstruction using: manubrio-incudo-stapedioplasty (13 patients), an autologous incus (19 patients) or a titanium ossicular replacement prosthesis (10 patients). For manubrio-incudo-stapedioplasty reconstruction, the malleus head was removed, the manubrium was relocated posteriorly and the incus short process was placed on the mobile footplate.
Revision Stapedectomy with Necrosis of the Long Process of the Incus: Does the Degree of Necrosis Matter? A Retrospective Clinical Study.
J Int Adv Otol
April 2017
Department of Otolaryngology, Mansoura University, Mansoura, Egypt.
Objective: To discuss the different modalities for managing necrosis of the long process of the incus in revision stapedectomy on the basis of the degree of necrosis and compare the results with those reported in the literature.
Materials And Methods: Thirty-six patients underwent revision stapedectomy with the necrosis of the long process of the incus from 2009 to 2016. The patients were divided into three groups on the basis of the degree of necrosis.
A Comparison Study of Partial Ossicular Reconstruction Prosthesis (PORP) Placement under the Malleus or Tympanic Membrane Graft in the Presence of the Malleus.
J Int Adv Otol
August 2017
Department of Otorhinolaryngology, Üsküdar State Hospital, İstanbul, Turkey.
Objective: The aim of this study was to compare the hearing results of embedding the partial ossicular reconstruction prosthesis (PORP) underneath the malleus with the malleus relocation technique and tympanic membrane graft in the presence of the malleus.
Materials And Methods: A retrospective review of patient charts and audiometric results in a tertiary referral center was conducted. In total, 83 patients who underwent intact canal tympanoplasty with mastoidectomy between 2010 and 2015 were included and divided into two different groups: malleus assembly to the stapes head (MASH) and tympanic membrane assembly to the stapes head (TASH).
