During its course, the STA gives off the middle temporal artery just above the zygomatic arch: It perforates the deep temporal fascia, giving branches to the temporalis muscle.The zygomatico-orbital branch runs between the two layers of deep temporal fascia, parallel to the zygomatic arch, to the lateral orbital angle.

Tympanoplasty refers to any operation involving reconstruction of the tympanic membrane and/or the ossicular chain. Myringoplasty is a tympanoplasty without ossicular reconstruction. Over the years many methods have been used for closing perforations. The most widely used and accepted method is underlay graft of temporalis fascia or sometimes perichondrium. Cartilage has become increasingly popular as a graft material, particularly when the tympanic membrane is retracted (see discussion of myringoplasty in ‘Inactive squamous chronic otitis media’ below). The basic procedure is to excise the rim of the perforation so that there is a raw surface from which new tissue will grow. The mucosa on the undersurface of the remaining tympanic membrane near to the perforation is removed or scraped with a sickle knife or similar instrument to provide a bed for the graft. This is then placed under the tympanic membrane remnant and acts as a scaffold for new growth of the squamous epithelial layer. The mucosa over the promontory should be carefully preserved to reduce the likelihood of post-operative adhesions between the graft and the promontory.
How to master MCQs

Branches of posterior ciliary artery supply the optic nerve head. Ischaemia causes optic nerve head swelling. Compared with the non-arteritic form, the visual loss in giant cell arteritis is usually profound and more often bilateral, unless steroid treatment is carried out early. C-reactive protein is a better indicator of response to treatment because its concentration changes more quickly with the amount of inflammation. The temporal artery lies on the temporalis fascia. Skip lesion may give a negative temporal artery biopsy but does not correlate with the severity of the disease.
Reconstruction of necrotizing soft tissue infection in the auricle and temporal region: a case report

An emergency debridement was performed. The necrotic skin was excised, and additional skin incisions were made so that the necrosis of the subcutaneous tissues could be confirmed. The necrotic subcutaneous tissue and temporal fascia were excised one layer at a time. Visually, the temporalis muscle did not appear to have obvious necrosis. Furthermore, the upper portion of the auricle was detached by debridement, and a color change occurred due to insufficient blood flow. To salvage the auricle, the temporalis muscle flap was elevated above the periosteum and inverted to cover the auricle (Figure 2). A second debridement was performed 12 days later, and the necrotic skin and periosteum were excised. Negative-pressure wound therapy (NPWT) was started at the end of surgery (Figure 3). A third debridement was performed 26 days after. Because of the exposed temporal bone, the extracranial plate was shaved until petechial hemorrhage could occur, and the artificial dermis was applied (Figure 4). NPWT was used for 9 days to fix the artificial dermis. When purulent exudation and edematous granulation increased, local treatment consisted of washing and dressing to achieve wound bed preparation and good granulation of the ulcer surface. The artificial dermis was successfully applied, and the skull was no longer exposed due to granulation.

From June 2016 to July 2018, 53 patients with a confirmed diagnosis of CSOM in the Department of Otolaryngology at Chinese PLA General Hospital received type I tympanoplasty described by Wullstein (type I–V) [5]. They were aged 16 years old and above. Those with recurrent ear drainage before surgery and preoperative air–bone gap (ABG) above 30 dB or combined with diabetes, hepatitis B and tumors were excluded. Before surgery. All patients received a high-resolution thin-slice CT scan of the temporal bone, hearing test, otoscopy, and ETS evaluation before surgery. All surgeries were performed under general anesthesia by a senior surgeon who had at least 10 years of working experience and had performed tympanoplasty for over 500 cases. Temporalis fascia was used as graft materials under a similar microscopically assisted procedure.

First, the posterosuperior incision is made, and the posterior meatal skin is elevated from the bony canal (Figure 1(A)). The stenotic bony ear canal is widened by drilling in the posterior bony ear canal, and a new large EAC is created (Figures 1(B) and 2). In cases with a well-pneumatized mastoid, complete mastoidectomy is not performed, and Korner’s septum is preserved as much as possible. Then, the reconstructed TM and EAC are placed on the septum, in order to maintain the tract from the antrum to the peripheral mastoid structures with preservation of the pneumatized mastoid air cells (Figures 3 and 4). Though LTM is not associated with a stenotic bony ear canal, the same surgical procedure is performed, and a functional (well mobilized), wide TM is made. The attic is exposed widely (Figure 1(C)). After assessing the ossicular chain, tympanoplasty is performed according to the status of the middle ear. The exposed mastoid air cells are covered with bone pate (paste) and soft-tissue or muscle flaps. The meatal skin is opened like a double door (Figure 1(D)), which creates a large opening of the EAC (Figure 5). The temporalis fascia is used as a graft material and placed over the exposed middle ear space and ossicular chain. The temporalis fascia is laid by the underlying method, and a new, wide TM is created (Figure 1(E)).
