During the past 25 years many variations have emerged in stapedectomy, most of which centered around either a change in the prosthesis itself or in the type of oval window seal. The small fenestra stapedectomy technique (SFT) represents a change in surgical procedure rather than in prosthetic design. This technique offers the opportunity to improve hearing results while reducing risks in stapedectomy surgery. Four areas of significant improvement are seen in patients in whom the SFT was used: (1) improved hearing in the high frequencies of 2000, 4000, and 8000 Hz, (2) improved speech discrimination scores, (3) a significant reduction in the number of reported vestibular complaints, and (4) a reduction in the number of serious postoperative sensorineural hearing losses.
The small fenestra stapedectomy is based on a rationale of creating a more effective acoustical mechanical transmission system, while reducing potential labyrinthine disturbance. Surgical technique for the small fenestra stapedectomy is described, including the creation of the fenestra and the use of McGee stainless steel piston prosthesis with loose areolar tissue around the piston. Postoperative results are compared in a series of 100 cases, 50 having the small fenestra technique, SFT, and 50 having partial or total footplate removal procedure. Vestibular results demonstrate a noticeable reduction in postoperative complaints of balance disorders in the SFT patients. Hearing results, when compared between the two groups, show a statistically significant advantage for the SFT patients in postoperative high frequency threshold sensitivity and speech discrimination scores. Technical difficulties in creating the fenestra without fracturing the entire footplate are discussed and suggestions made for their avoidance. The advantages of lowered risk, based on reduced trauma to and contamination of the labyrinth, as well as improved high frequency hearing sensitivity and speech discrimination, support the use of this procedure and call for further investigation and development of its clinical potential.
A brief history of the surgical technique of tympanoplasty is provided, emphasizing the underlying principles and goals as defined by Wullstein. Based on clinical and surgical experience, a list of absolute and relative contraindications to tympanoplasty surgery is presented according to the presence or absence of active pathology.
The postoperative formation of attic retraction pockets following tympanoplasty, with or without mastoidectomy, has often been a significant cause of recurrent disease accompanied by decreased hearing levels. Nasal septal cartilage is recommended as a successful homograft material for attic support. The basis and indications for its use are discussed. Preparation and storage of the homograft materials and surgical technique are described. Long‐term results are reported, including a special group in which the status of the homograft material was assessed during revision surgery. Minimal complications have been encountered.
Conclusions support the overall advantages of this technique utilizing homograft septal cartilage as an effective means of posterosuperior canal wall support, an aid in preventing retraction pocket formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
