Objective:To compare the differences in postoperative healing rates, hearing improvement, and complication rates between endoscopic butterfly inlay cartilage tympanoplasty and underlay cartilage tympanoplasty in Small-to-Medium-Sized Tympanic Membrane Perforations, and to provide clinical basis for indication of the butterfly inlay cartilage tympanoplasty. Methods:This study enrolled patients with chronic suppurative otitis media or traumatic tympanic membrane perforations who were treated at the Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Chongqing Medical University, between January 2022 and May 2023. Inclusion criteria comprised a dry ear period exceeding 3 months, absence of middle ear or mastoid pathology confirmed by temporal bone CT, and an air-bone gap of less than 40 dB. All surgeries were performed by the same surgeon using tympanoplasty techniques. Based on the surgical approach and perforation size, patients were categorized into four groups: Group A（butterfly cartilage tympanoplasty, perforation ≤3 mm）: 23 cases. Group B（butterfly cartilage tympanoplasty, perforation 3-5 mm）: 17 cases. Group C（full-thickness cartilage underlay tympanoplasty, perforation ≤3 mm）: 12 cases. Group D（full-thickness cartilage underlay tympanoplasty, perforation 3-5 mm）: 22 cases. Data collected included perforation duration, preoperative Eustachian Tube Score（ETS）, pure-tone audiometry, otoscopic findings, and postoperative follow-up data on pure-tone thresholds, otoscopic outcomes, and complications such as graft infection and otorrhea. Results: The mean postoperative follow-up period was 4 months （range: 3-12 months）. A total of 74 patients were enrolled, including 40 undergoing butterfly cartilage tympanoplasty and 34 receiving full-thickness cartilage inlay tympanoplasty. In the <3 mm perforation subgroup, the patients receiving butterfly technique （23 cases） exhibited a postoperative air-bone gap （ABG） improvement of （2.33±8.21） dB, and those receiving the inlay technique （12 cases） showed an ABG improvement of （2.49±7.9） dB, with no statistically significant difference between the two groups （P>0.05）. In the 3-5 mm perforation subgroup, the patients receiving butterfly technique （17 cases） demonstrated an ABG improvement of （8.16±5.69） dB, and those receiving the inlay technique （22 cases） achieved an ABG improvement of （8.08±10.42） dB, which were not significantly different （P>0.05）. Tympanic membrane healing rates across the four subgroups were 95.65%, 94.12%, 100%, and 95.45%, respectively, with no statistically significant differences （P>0.05）. Conclusion:In patients with tympanic membrane perforations ≤3 mm and 3-5 mm, butterfly cartilage tympanoplasty achieves comparable audiological outcomes to full-thickness cartilage underlay tympanoplasty. Compared with the underlay technique, the butterfly method is less invasive, preserves the normal anatomical structure of the tympanic membrane, requires a shorter dry ear period, and yields higher patient satisfaction. Therefore, it can be safely recommended for perforations ≤5 mm that do not require tympanotomy exploration.

OBJECTIVE: To explore the effect of the canalplasty for inlay myringoplasty. METHOD: A retrospective study was performed on 125 patients (130 ears) who underwent canalplasty and myringoplasty for the treatment of the chronic otitis media. The postauricular incisions was made, then the separation of the flap of posterior canal skin and the tympanic membrane epithelium, mill addition to part of the canal bone of the top, bottom, behind. Lift forward on the anterior canal skin, until the formation of the external auditory canal skin tube. Metal sheets was used to protect the skin tube, mill addition to the prominent bone of the anterior canal, reveal the tympanic anulus fully. Explore the ossicular chain activities, fascia covering the canal and fiber layer surface of the drum remnant was used as an inlay graft, and the canal skin was replaced. The canal was filled with hemostatic gauze and hemostatic sponge. Stitches a week after surgery. Removal of filling material in the external auditory canal two weeks after surgery, and re-filling with sterile gauze until healed. RESULT: All 125 patients had successful grafts with 100% survival rate and healed in stage I. Average improvement in air-bone gap for all patients was 8.9 dB. Stenosis of the external auditory canal and lateralization of the grafted drum did not occur. Follow-up was conducted for 1-3 years. Three ears had reperforation and eight ears had late atelectasis. Fifteen ears had myringitis and healed by halometasone cream. CONCLUSION Canalplasty is an important surgical procedure on inlay myringoplasty. It can make the narrow and curved canal to large, eliminate the prominent bone of the anterior wall, expose the perforation edge fully, further facilitate the survival of the graft and post-operative care.

OBJECTIVE: To explore the clinical effectiveness of endoscopic myringoplasty with homoplastic amniotic membrane. METHOD: A retrospective study in 43 patients underwent endoscopic myringoplasty with homoplastic amniotic membrane was observed at the wound healing of tympanic membrane perforation and the hearing improve-threshold audiometry in 43 patients after surgery. RESULT: The tympanic membrane's perforation healing rate was 95.3% (41/43), and air conduction threshold audiometry in language frequency improved average 10 dB. The follow up was 1--4 years, and no recurrence or complications had occurred. CONCLUSION The endoscopic myringoplasty could be able to simple myringoplasty whose air conduction threshold audiometry in language frequency was less than 40 dB. It could be used to repair not only the central perforation in tympanic membrane, but also the marginal perforation which has residual tympanic membrane in most of the regional. Human amniotic membrane is an ideal materials for repair of tympanic membrane.

OBJECTIVE: To explore the curative effect of endoscopic myringoplasty with modified sandwich technique. METHOD: Endoscopic myringoplasty was performed with modified sandwich technique for traumatic perforation of tympanic membrane and chronic suppurative otitis media (simple type) of 43 patients. RESULT: All the perforating tympanic membranes were repaired successfully in one time. Six months after the operation, 1 case was out of follow-up and 2 cases were failed: one got a small perforation when the transplantation shifted and the transplantation of the other one was lost because of infection. The closure rate of tympanic membrane perforations was 95.2%. The air-bone gap of speech frequency of 28 ears increased by > 15-20 dB, 8 ears were enhanced by 10-15 dB, while 6 ears (including 2 failed cases) without improvement. The acoustic immittance test showed that "Type A", "Type As", "Type Ad", "Type B" and "Type C" tympanogram were in 30 ears,12, 4, 6 and 4, respectively. CONCLUSION The endoscopic myringoplasty with modified sandwich technique has the advantages of simple operation, better security, less trauma and better efficacy, and it is worth popularizing.

OBJECTIVE: To evaluate the effect of over-under myringoplasty technique on repairing tympanic membrane perforation regarding with the rate of perforation closure, the frequency of postoperative complications occurrence and the level of hearing improvement. METHOD: In this retrospective study, a total of 74 patients (77 ears) underwent myringoplasty and had been followed up for over 6 months, which was performed by means of the underlay technique in 44 patients (45 ears) and over-under technique in 30 patients (32 ears) from Jan 2002 to Jan 2007. In the underlay group, the grafted membrane was placed medial to the remaining drum and the manubrium of the malleus. In the over-under group, the grafted membrane was placed under the remaining drum and over the malleus. Comparatively evaluate the effect of the underlay technique and that of the over-underlay technique on repairing tympanic membrane perforation. RESULT: The rate of perforation closure and hearing improvement in the underlay group of 45 ears was 89.0% and 57.5% respectively, while that in the over-under group of 32 ears were 87.5% and 71.9% respectively. The air-bone gap decreased by 4.9 dB in the underlay group, while it decreased by 9.7 dB in over-under group. After more than 6 months of following-up, the frequency of postoperative atelectasis of the underlay group and the over-under group was 17.8% and 6.25% respectively. Meanwhile, the frequency of postoperative reperforation of these two groups was 5.9% and 6.25% respectively. Blunting of the anterior angle of the tympanic membrane occurred in 3 ears in the over-under group. Lateralization of the graft was not observed in either group. CONCLUSION Over-under technique could reduce the occurrence of the adhesions between the grafted membrane and promontorium tympani by placing the grafted membrane between the remaining drum and the malleus. Furthermore, the level of hearing improvement in over-under group was higher than that in underlay group. Over-under myringoplasty is a more effective technique as comparison to underlay myringoplasty for repairing middle to large tympanic membrane perforations.
