AbstractBackgroundTotally endoscopic ear surgery and endoscope-assisted microsurgery are still new concepts, with relatively few centres in the UK performing them. Advantages include better visualisation of difficult to reach areas, such as the sinus tympani, and limited external incisions. This paper reports our short-term outcomes for endoscopic middle-ear surgery.MethodsA prospective review was conducted of the first 103 consecutive patients undergoing totally endoscopic ear surgery or endoscope-assisted microsurgery in 1 centre performed by 1 operator. The outcomes assessed were: tympanic membrane healing, audiological data and complications.ResultsTwenty-five patients underwent endoscope-assisted microsurgery, while 78 had totally endoscopic ear surgery. There were no reported cases of dead ear or permanent facial nerve palsy. The average air–bone gap following stapedectomy was 7.38 dB. The tympanic membrane healing rate was 89 per cent.ConclusionOur results confirm that endoscopic middle-ear surgery is safe, and the short-term outcomes are comparable with conventional surgery.

Background: Endoscopic ear surgery has recently increased, but it is still inconvenient and time-consuming to place packing material in the middle ear with one hand. Poloxamer 407 (P407) is a thermo-reversible gel that can be easily administered with one hand into the middle ear cavity in liquid form. Upon warming to body temperature, the gel form of P407 can support the graft in the target position and is known to prevent postsurgical tissue adhesion. Objectives: We aim to investigate the feasibility of P407 as packing material in an animal model. Male Hartley guinea pigs (350 and 400 g) were utilized in this study. Method: The animals were randomly divided into 3 groups according to the packing material: the control group, the P407 group, and the gelatin group. To assess the role of packing material on bacterial colonization, left ears were inoculated with Streptococcus pneumoniae through the tympanic membrane using a 0° endoscope. Five days after inoculation, the middle ear cavity was packed through a transbullar approach using 18% P407 or gelatin in both ears. In the control group, no ear pack was inserted. The tympanic membrane was examined every week using a 0° 1.9-mm endoscope until 6 weeks. Half of the animals in each group were sacrificed 6 weeks after placement of the packing materials. Results: Compared with the absorbable gelatin sponge, the P407 group showed little inflammation or fibrosis in the tympanic membrane and middle ear mucosa regardless of bacterial inoculation. The gelatin group showed severe otorrhea or perforation until 2 weeks in the right ear (2 of 4) and the left ear (1 of 4). Even though the endoscopic findings were similar between both packing groups at 6 weeks, histological analysis showed persistent packing material, inflammatory cells, and fibrosis in the gelatin group compared to the P407 group. Conclusions: This study suggested that P407 is feasible as a packing material to handle with one hand and to prevent adhesion, especially in infected middle ear mucosa. Although there is a lack of data on how well P407 supports grafts, we suggest that P407 could be a candidate for packing material in endoscopic ear surgery.

Objectives: We evaluated the closure rate after fat-graft myringoplasty (FGM) of perforations differing in size and location. We explored whether patient’s factors and the FGM surgical technique influenced surgical outcomes. Methods: We retrospectively studied patients with tympanic membrane perforations who underwent FGM from March 2015 to March 2019. All procedures were performed by a single senior surgeon at our tertiary hospital. The patients who followed-up for at least 6 months after surgery were enrolled. We recorded hypertension and diabetes status, age, any prior ear surgery, any calcific plaques adjacent to the perforation, and perforation size and location. Results: A total of 150 patients were enrolled. Our success rate of FGM was 90%. Hypertension, diabetes, prior ear surgery history, and eardrum calcific plaques did not affect the surgical outcomes. There was no statistical difference in the surgical success rate according to the size (< 50%) or location of perforation. The closure rate was 97.2% in patients aged 1660 and 87.5% in patients aged > 60, respectively. However, FGM was successful in only two of six children (33.3%) aged ≤ 15 years, thus significantly less than in the other groups. Conclusion: FGM is a fast, safe, and efficient method for repairing tympanic membrane perforation. The surgical outcome is not significantly affected by underlying disease, perforation size or location, or by the condition of the tympanic membrane or older age. However, it may be poor in children with dysfunctional Eustachian tube.
