Rare Group

Benign middle ear tumors represent a rare group of neoplasms that vary widely in their pathology, anatomy, and clinical findings. These factors have made it difficult to establish guidelines for the resection of such tumors. Here we present 7 unique cases of these rare and diverse tumors and draw from our experience to recommend optimal surgical management. Based on our experience, a postauricular incision is necessary in nearly all cases. Mastoidectomy is required for tumors that extend into the mastoid cavity. Whenever exposure or hemostasis is believed to be inadequate with simple mastoidectomy, canal-wall-down mastoidectomy should be performed. Finally, disarticulation of the ossicular chain greatly facilitates tumor excision and should be performed early in the procedure.

Abstract Aims The aim of this study was to evaluate the surgical outcome of cavity obliteration with bioactive glass in patients with cholesteatoma undergoing canal wall down mastoidectomy with reconstruction of the canal wall. Materials and Methods A prospective study was conducted over a period of 3 years on 25 patients who underwent mastoid obliteration with bioactive glass following canal wall down mastoidectomy for cholesteatoma. The primary outcome measure was the presence of a dry, low-maintenance mastoid cavity that was free of infection, assessed, and graded according to the grading system by Merchant et al at the end of 1 and 6 months postoperatively. Secondary outcome measures included presence of postoperative complications like wound infection, posterior canal wall bulge, and residual perforation. Results Out of the 25 patients on whom this study was conducted, at the end of 1 month 60% had a completely dry ear, 28% of patients had grade 1, and 12% had grade 2 otorrhea at the end of the first month. At the end of 6 months, 72% had a completely dry ear, while 20% had grade 1 and 8% had grade 2 otorrhea. There were no cases with grade 3 otorrhea during the entire follow-up period. Postoperative complications of the posterior canal bulge were noted in two patients (8%), and one patient (4%) had a residual perforation. Conclusion Mastoid cavity obliteration with bioactive glass is an effective technique to avoid cavity problems.

Canal Wall Down Mastoidectomy

Objectives: Mastoid reconstruction principle had been described to overcome problems of chronic discharging cavity. Different materials were used; nonbiologic materials seem to be less preferred. Platelet-rich plasma (PRP) could promote the regeneration of mineralized tissues. In this work, the authors present a simple and easy technique for mastoid reconstruction with PRP and cortical bone pate. Methods: The study design is a case series. Patients had mastoid reconstruction after canal wall down mastoidectomy using PRP and cortical bone pate. Results: This study included 21 patients: 9 males, and 12 females. Sixteen patients had left side disease. All surgical procedures were conducted smoothly within 90 to 135 minutes with no stressful events had been reported. At 12 to 16 months of follow-up, external canal stenosis and mastoid fistulas were not reported. Good healing of the tympanic membrane was seen in 18 patients. No radiological signs suggestive of recurrence were detected and the reconstructed mastoid cavity was smooth and well aerated. Residual tympanic membrane perforations were detected in 3 patients. Conclusion: Autologous materials (PRP and bone pate pate) after canal wall down mastoidectomy appear to be a reliable and effective choice for mastoid reconstruction.

AbstractObjectiveSafe cochlear implantation is challenging in patients with canal wall down mastoid cavities, and the presence of large meatoplasties increases the risk of external canal overclosure. This paper describes our results of obliteration of the mastoid cavity with conchal cartilage as an alternative procedure in cases of canal wall down mastoidectomy with very large meatoplasty.MethodsThe cases of seven patients with a canal wall down mastoidectomy cavity who underwent cochlear implantation were retrospectively reviewed. Post-operative complications were analysed. The mean follow-up duration was 4.5 years.ResultsThere was no hint of cholesteatoma recurrence and all patients have been free of symptoms during follow up. Only one patient showed cable extrusion six months after surgery, and implantation of the contralateral ear was needed.ConclusionPseudo-obliteration of the mastoid cavity with a cartilage multi-layered palisade reconstruction covering the electrode may be a safe alternative in selected patients with a large meatoplasty.

Background: Pre-operative and post-operative hearing status and status of mastoid cavity were compared in patients undergoing canal wall down mastoidectomy (CWDM) with tympanoplasty.Methods: Forty-three patients who underwent surgery and completed their follow up post-surgery were included in the study. Nineteen patients underwent CWDM with type III tympanoplasty with PORP, 7 patients underwent CWDM with type III tympanoplasty without PORP and 17 patients underwent CWDM with type IV tympanoplasty with TORP.Results: Among enrolled patients, 21 patients were females and 22 patients were male. Right ear (29) was commonly involved than left ear (14). Hearing loss was predominant symptom followed by recurrent ear discharge and other symptoms. Patients underwent three types of surgeries, type III tympanoplasty with PORP (19/43), type III tympanoplasty without PORP (7/43) and type IV tympanoplasty with TORP (17/43) by using Teflon prosthesis.Conclusions: Thirty seven percent (16/43) of patients had hearing threshold <25 dB post-surgery with maximum improvement in group A 47% (9/19). Forty seven percent (20/43) patients had hearing threshold between 26-40 dB with maximum improvement in group B 43% (3/7). Twelve percent (5/43) patients had hearing threshold between 41-60dB with almost equal improvement in all three groups. Five percent (2/43) of patients had >60dB hearing threshold, all belonging to group C. Anatomical results were assessed by examining the mastoid cavity showing 95%, 72%, 70% patients in group A, B and C had well epithelialized cavity.

Canal Wall Down Mastoidectomy

<p>Post aural fistula is one of the complications of squamous variety of chronic otitis media (COM-S). For decades together a lot of new surgical techniques have been introduced in the treatment of COM-S out of which canal wall down mastoidectomy is most commonly practised. Despite these efforts many patients presenting with COM-S end up in tertiary referral centers at a late stage with complications like fistulas and by this time a number of procedures have already been done on them. A 19 year old female presents with Postaural fistula as a complication of COM- S type. Due to the local scarring, newer flap options needed to be sought to obliterate the mastoid cavity. This article demonstrates the extra dimension for the usage of fasciocutaneous flap from neck region to treat patients of recurrent postaural fistula.</p>

Canal Wall Down Mastoidectomy

AbstractAim:(1) To assess hypersensitivity to bismuth iodoform paraffin paste impregnated ribbon gauze following its use in packing canal wall down mastoidectomy cavities; (2) to determine if isolation of the skin and mucosa from the pack, using thin Silastic sheeting and Cortisporin ointment, reduces hypersensitivity reactions, compared with a previous series; and (3) to review the literature and to determine if bismuth iodoform paraffin paste hypersensitivity precludes the consumption of seafood (due to its high iodine content).Materials and methods:All patients undergoing canal wall down mastoidectomy with intra-operative bismuth iodoform paraffin paste packing between 1985 and 2009 were identified and reviewed.Results:Of 587 patients identified, the overall bismuth iodoform paraffin paste reaction rate was 1 per cent. All reactions were in patients undergoing revision mastoidectomy procedures, giving a reaction rate for revision procedures of 2.4 per cent.Conclusion:Reactions are an uncommon event following post-operative mastoid cavity packing using bismuth iodoform paraffin paste. Reaction rates may be lowered by preparing the cavity with Silastic sheeting and Cortisporin ointment prior to packing, thus isolating the skin and mucosal surfaces. Development of such a reaction does not preclude the consumption of seafood.
