目的 探讨外耳道腺样囊性癌的临床病理特点，总结疗效。方法 回顾性分析1985-2001年收治的8例外耳道腺样囊性癌患者的临床资料。结果 8例患者中行局部肿瘤切除2例；行外耳道袖状切除加腮腺浅叶切除2例；行肿瘤切除加扩大乳突根治3例（1例手术5次，最后1次行颞骨次全切除术）；行耳廓全切除加颞骨次全切除术1例。后4例术后辅以放疗。随访5～15年，2例健在，2例6年后肺转移带瘤生存，2例8年后死于肺转移，2例失访。结论 外耳道腺样囊性癌早期确诊和彻底手术是延长患者生命的关键。肿瘤易发生肺转移，远期预后不佳，提倡综合治疗。     

Temporal bone resection.

It must be emphasized that the greatest impact of survival can only be obtained through an early diagnosis and a radical treatment program. Any granulation tissue must be sent for biopsy to rule out the possibility of malignancy in the setting of chronic otitis media. Once carcinoma is diagnosed, imaging studies must be obtained to define the extent of the tumor. Under diagnosis is the rule with these malignancies. Tumors limited to the external auditory canal can be adequately resected with a lateral temporal bone resection. Extension into the middle ear and mastoid aircell systems requires either a subtotal temporal bone resection or a lateral temporal bone resection with a radical mastoidectomy and petrousectomy. The inclusion of the petrous apex with the resection, as in a temporal bone resection, does not add to survival but increases morbidity. Radical postoperative radiation therapy is essential for maximum local control and survival with these malignancies.

Carcinoma of the external auditory canal and middle ear: therapeutic strategy and follow up

BACKGROUND: Carcinomas of the external auditory canal (EAC) and the middle ear are rare and considered to have a poor prognosis. The recommended therapeutic strategy consists of surgical excision and postoperative radiotherapy. However, there are different opinions about the extend of the primary operation. PATIENTS AND METHODS: A series of 21 patients with carcinoma of the EAC and middle ear were treated at the ENT-Department of the Hospital Fulda from 1985 to 2003. Their records and radiologic findings were reviewed retrospectively with particular reference to tumor type and size, its relation to surrounding tissues, surgical procedures and radiation techniques. The tumors were staged according to the modified Pittburgh staging system for temporal bone carcinomas. The average follow-up time was 6.2 years (range 0.2 - 18.75). RESULTS: 17 patients suffered from carcinoma of the EAC, 4 carcinomas were primarily located in the middle ear. There were 15 squamous cell carcinomas, 3 adenoidcystic carcinomas, 2 adenocarcinomas and one mucoepidermoid carcinoma. 12 patients came primarily to our institution and were staged as follows: pT1 (n = 2), pT3 (n = 2), pT4 (n = 8). 8 patients showed up with recurrent or residual tumors (all of T3 or T4 stage). One patient could not be classified. In 5 cases the tumor was inoperable. These patients underwent combined chemoradiation therapy. All other 16 patients were operated and most of them received adjuvant radiation therapy. In the group of patients who were primarily operated overall 5-year survival rate was 100 %. In contrast, patients who's recurrent or residual tumors were resected had a 5-year survival rate of only 33 %. Patients who received combined chemoradiation therapy showed a 2-year survival rate of 75 %. CONCLUSION: Carcinoma of the EAC and middle ear should be treated primarily by a lateral or subtotal temporal bone resection stage dependent combined with a parotidectomy as well as a neck dissection. Local resection of the EAC is not sufficient, not even in T1 tumors. As from stage T2, in cases of recurrent tumor removal and questionable free margins as well as in cases with lymph node metastases an adjuvant radiation therapy should be added. The most important survival factor is removal of the primary tumor with histologically clear margins.     

中耳恶性肿瘤33例临床分析

目的探讨中耳恶性肿瘤的临床特点和治疗策略。方法回顾性分析解放军总医院1997～2007年经治的33例中耳恶性肿瘤患者,其病理类型分别是25例鳞状细胞癌．5例腺癌,2例粘液表皮样癌及1例横纹肌肉瘤。结果按照Stell分期为Ⅰ期2例,Ⅱ期12例,Ⅲ期19例。8例行扩大的乳突根治术,19例行颢骨次全切除术,6例接受颞骨全切除术。以阔筋膜修复缺损的硬脑膜,以胸大肌皮瓣、胸锁乳突肌瓣、颞肌瓣等单独或联合修复术腔缺损。1例患者单独接受手术治疗,32例患者接受手术＋放疗的综合治疗。全组总的3年、5年生存率分别是85．2％、74．7％。有血性耳漏患者与无血性耳漏患者的3年生存率分别是74．1％和89．1％（P=0．049）。结论对中耳恶性肿瘤的患者采取扩大切除加术后根治性放疗可提高生存率,持续的血性耳漏可能是预后不良的表现。     

A retrospective analysis of surgical operations on malignancies of the ear]

In the past 20 years from 1970 to 1990, 21 patients with malignancies of the ear were treated at Cancer Institute Hospital. The primary sites were the auricle and cartilaginous external auditory canal (group 1: n = 8), the bony external auditory canal (group 2: n = 6) and the middle ear (group 3:n = 7). In group 1, pathological types were squamous cell carcinoma in four patients and basal cell carcinoma in the other four patients. Seven patients were treated by surgery alone, and the remaining patient was treated by interstitial implant radiotherapy. No recurrence have been noted up to today in this group. In group 2, pathological types were squamous cell carcinoma in four patients and adenoid cystic carcinoma in the other two patients. All of the six patients underwent external canal resection or subtotal temporal resection. Two patients received postoperative radiotherapy. A five year survival rate of group 2 was 60%. In group 3, pathological types were squamous cell carcinoma in six patients and undifferentiated carcinoma in the remaining patient. Most of them underwent radical mastoidectomy followed by irradiation. However, all the patients died within two years after treatment. In group 2 and 3, cytodiagnosis was useful for early discovery. In group 2, temporomandibular joint seemed to be a key point in surgical treatment. In group 3, the combination of conservative surgery with radiotherapy was not a radical treatment. This suggested it necessary to perform subtotal temporal resection to treat malignancy of the middle ear.     

颞骨次全切除术治疗外耳道腺样囊性癌的疗效分析

目的 探讨颞骨次全切除术在外耳道腺样囊性癌的临床应用效果。方法 回顾性分析2015—2019年收治的8例外耳道腺样囊性癌患者的临床资料，其中男2例，女6例；年龄33~76岁，平均年龄55.6岁。耳痛7例，外耳道肿块、耳溢液、听力下降各6例，面瘫1例；从最初出现症状到确诊平均为2.75年，5例曾被误诊，3例曾被误治手术；6例行颞骨次全切除+腮腺浅叶切除术，2例行颞骨次全切除+全腮腺切除术。结果 围手术期内1例患者出现局部切口感染，1例出现脑脊液漏。全部患者平均随访4.34年；6例患者无瘤存活；1例复发患者于我院二次手术后3年再次出现局部复发伴肺转移，接受放射治疗，目前带瘤生存；1例患者术后随访3.5年死于其他疾病。结论 外耳道腺样囊性癌早期症状不典型，容易误诊；确诊后应实施颞骨次全切除术以达到彻底切除肿瘤目的，术中应同时处理腮腺；术后放疗也是一种可选择的补充治疗手段。

Rhabdomyosarcoma of the temporal bone. Is surgical resection necessary?

Three patients had embryonal rhabdomyosarcoma of the temporal bone. Their clinical appearances demonstrated the following characteristics: (1) symptoms of an acute process in the middle ear cleft and mastoid, (2) a rapidly growing polypoid mass that was visible in the middle ear and external auditory canal, and (3) seventh nerve involvement and destruction of bone. Definitive treatment with the use of systemic chemotherapy and radiation therapy to the invaded structures was followed by maintenance chemotherapy for up to 24 months. Surgical treatment was sufficient to obtain adequate biopsy material. All patients recovered variable degrees of motor nerve functions. One patient experienced a meningococcal meningitis years after treatment; this condition resulted in total deafness. The results suggest that multiple-drug chemotherapy and radiation therapy for all involved areas are the mainstay of treatment for this disease entity.     

Malignant neoplasms of the external auditory canal and temporal bone

In a review of 136 patients with squamous cell, basal cell, and salivary gland cancers involving the external auditory canal and temporal bone, the majority of patients had received prior treatment and came to us with recurrent tumor. Squamous cell carcinoma of the concha and cartilaginous ear canal behaved aggressively. Five-year survival in 35 patients with deep temporal bone involvement was 29%. The major reason for failure in this group was incomplete resection of disease. Postoperative irradiation was of no benefit when the cancer could not be completely excised. When compared with surgery alone, combined therapy with postoperative irradiation did improve local control in patients with completely resected lesions but did not demonstrate a corresponding increase in five-year survival.     

Bilateral inverted papilloma of the middle ear with intracranial involvement and malignant transformation: first reported case

Inverted (Schneiderian) papilloma (IP) is a benign but locally aggressive tumor that is typically located in the sinonasal tract. Middle ear involvement and intracranial extension are rare. We present a patient with a history of a completely resected right nasal cavity IP that returned 7 months later with hearing loss, bilateral aural fullness, and right-sided facial weakness. Work-up revealed middle ear IP, and the patient underwent bilateral mastoidectomies. On both sides, the disease caused erosion of the tegmen and was adherent to the underlying dura. There was dehiscence of the carotid canal wall on the left. On the right, the tumor was discovered to have recurred 3 months after initial resection, resulting in complete facial nerve paralysis and trigeminal paresthesias. A right temporal bone resection was undertaken along with neurosurgery. The IP was discovered to have invaded through the dura of the temporal lobe, incase the internal carotid artery, and infiltrate the trigeminal nerve. The facial and vestibulocochlear nerves were sacrificed on the right. Pathology of the right temporal bone revealed malignant transformation to squamous carcinoma. The patient was referred to radiation oncology for postoperative therapy. To our knowledge, this is the first case of bilateral IP of the middle ear with intracranial involvement and malignant transformation. Discussion points include: 1) management of middle ear IP, 2) carotid canal wall dehiscence in erosive middle ear disease, 3) aggressive surgical excision in locally destructive middle ear tumors, and 4) the role of radiation therapy in malignant transformation of IP.     

Bilateral middle ear squamous cell carcinoma and clinical review of an additional 5 cases of middle ear carcinomas

We reported a retrospective review of the clinical records for a 64 year old male patient with bilateral middle ear squamous cell carcinoma (MESCC), and for the five other patients with MESCC treated at our institution during the last 20 years. The patient with bilateral MESCC has survived and remained tumor free for more than 1.5 years after extended radical resection of the secondary tumor combined with intra-arterial and systemic chemotherapy, radiotherapy and immunotherapy. Four patients with unilateral MESCC were treated with multidisciplinary treatment (induction chemotherapy, surgery and radiotherapy), and the remaining patient was treated with radiotherapy and mastoidectomy. Five of the six patients are alive with no evidence of disease. The patient treated with radiotherapy and radical mastoidectomy died of local recurrence 3 years after diagnosis. We suggest that MESCC should be considered when refractory granulation, long-standing otorrhea, otalgia and facial paralysis are observed. Multidisciplinary treatment, including intra-arterial chemotherapy and en bloc resection of the temporal tumor is useful for the treatment of MESCC and will improve the prognosis of patients with this disease.     

Malignancies of the external ear canal and temporal bone: surgical techniques and results

A combined therapy approach to malignancies of the external auditory canal and middle ear has been developed. A technique of external canal resection and gross tumor removal from the middle ear, parotid gland, and superior cervical lymph nodes is followed by postoperative full-therapy irradiation. This combined approach has been used in 30 patients with malignancies involving the external auditory canal and temporal bone. The preoperative evaluation and surgical technique, including the intraoperative decision-making process, is described. Twenty-four patients had squamous cell carcinoma of the external auditory canal, and two patients had basal cell carcinoma. There was one patient each with adenocystic carcinoma, acinic cell carcinoma, high grade mucoepidermoid carcinoma, and a giant cell tumor of bone. This group of patients was broken down into three groups based on the extent of disease as determined at surgery. Overall control of disease, both locally and distant, for the 30 patients was 66%. There were 12 patients with disease limited to the ear canal. These patients had a 91% survival of this disease process. Seven patients were determined to have limited extension beyond the ear canal. These were treated with combined therapy with an overall control of disease of 72%. Eleven patients had extensive disease outside of middle ear into the carotid jugular spine, stylomastoid foramen, and skull base, with a survival rate of 45%. It is concluded that a step-wise removal of all gross tumor, as opposed to an en bloc dissection of the temporal bone and skull base, followed by full-therapy irradiation gives equally as good, or even better, long-term survival for this malignancy of the external auditory canal and middle ear.

Management of the temporal bone defect after resection of external auditory canal cancer

ObjectiveTo evaluate the surgical procedures used to treat external auditory canal cancer with respect to avoiding postoperative infection of the temporal bone defect.MethodsEnrolled in the study were 52 patients with external auditory canal cancer surgically treated between July 2015 and October 2020 (38 lateral temporal bone resections, 12 subtotal temporal bone resections and 2 partial resections, accompanied by various combined procedures). Retrospective chart review was conducted taking into consideration postoperative infection, and univariate analysis of prognostic factors was performed.ResultsIn cases managed with subtotal temporal bone resection, no postoperative infections occurred. Cases managed with subtotal temporal bone resection demonstrated increased use of free-flap reconstruction, and longer antibiotic infusion period. On the other hand, analysis of cases managed with lateral temporal bone resection revealed 10 out of 38 patients with postoperative infection (26.3%). However, we couldn't find out any factors that contributed significantly to the prevention of postoperative infection, including the surgical procedures used to manage the defected space, which included free-flap implantation, obliteration with fat tissue, muscular flap rotation, and leaving the space empty without obliteration or reconstruction.ConclusionIn cases managed with lateral temporal bone resection, leaving the resected space empty did not increase the risk of infection. On the other hand, in cases with subtotal temporal bone resection, filling the surgical defect with an autologous bulk, including the free-flap reconstruction and fat obliteration, seems to prevent the infection. Moreover, prolonged antibiotic infusion may suppress postoperative infection of the temporal bone defect.     

Bilateral primary carcinoma of the external auditory meatus]

We report an extremely rare case of bilateral primary carcinoma of the external auditory meatus. A 50-year-old man suffered 1 month from left-ear discharge and otalgia. Examination revealed a tumor of the left ear canal and a biopsy showed well-differentiated squamous cell carcinoma. The patient underwent 60 Gy radiotherapy and left subtotal temporal bone resection. A tumor with irregular swelling of the right external canal was found 8 months after the first diagnosis. Biopsy of the right external canal confirmed the same squamous cell carcinoma. Genetic examination that the carcinoma of the right ear was probably not a metastatic from the carcinoma of the left ear.     

Photofrin-mediated photodynamic therapy for treatment of aggressive head and neck nonmelanomatous skin tumors in elderly patients

OBJECTIVES/HYPOTHESIS: Aggressive nonmelanomatous skin tumors (basal cell carcinoma, squamous cell carcinoma, and Bowen's disease) of the head and neck often occur in Caucasian elderly patients because of prior history of radiation therapy for teenage acne and adenoid hypertrophy; severe solar-induced skin damage, basal cell nevus syndrome, and other genetic skin diseases; chemical carcinogen exposure; and drug-induced immunosuppression. In patients with large, multifocal recurrent tumors, standard therapy with acceptable cosmetic outcomes may be difficult. Photodynamic therapy (PDT) with photosensitizing agents selectively taken up by skin provides a primary or adjunct intraoperative option for treatment of this special group of cancer patients. STUDY DESIGN: Retrospective review. METHODS: Patients (age range, 60-92 y) were injected with 1.0 mg/kg PHOTOFRIN (dihematoporphyrin derivative) followed 60 hours later by intraoperative laser light activation. Light was delivered through microlens fiber by means of an argon dye laser at 630 nm at a light dose of 100 to 300 J/cm2 microlens delivery for PDT alone and 50 to 100 J/cm2 microlens delivery for tumor bed resection sites in the case of adjunct PDT combined with surgical resection. RESULTS: Twelve cases of aggressive recurrent nonmelanomatous cutaneous tumors of the head and neck were treated. Five patients received intraoperative PDT combined with surgical resection, including radical mastoidectomy, lateral temporal bone resection, partial maxillectomy with temporalis myofacial flap reconstruction, and wide local resection with secondary intention healing of exposed scalp wounds. Seven patients were treated with PDT alone for extensive multiple cutaneous lesions or wide-field primary or recurrent nonmelanomatous tumors. Ten patients achieved complete responses (follow-up, 6-60 mo) with excellent wound healing and cosmetic outcomes. CONCLUSIONS: PHOTOFRIN-mediated PDT is an excellent locoregional oncological modality for aggressive primary or recurrent basal cell carcinoma and squamous cell carcinoma, particularly in elderly patients who were previously treated with extensive Mohs microsurgery, surgical resection, and external-beam radiation therapy. Multiple repeat treatments are well tolerated, painless, without systemic morbidity, and amenable to local anesthesia or intravenous sedation for PDT alone, and wound healing and cosmetic outcomes are excellent.     

Management of Malignant Salivary Gland Tumors

A total of 54 patients with major salivary gland tumor were treated with radiation therapy at the University of Michigan from 1955 to 1975, inclusive. Fifteen had total resection and radiation, 16 had subtotal resection and radiation, and 23 were inoperable and received radiation only. Local control rate was different between these groups, 86.7%, 75%, 21.7% respectively, as was survival rate at 5 years, 78.4%, 59.8%, 29.9% In patients with facial nerve palsy, with combined surgery and radiation, 65.3% local control and 49.7% 5year survival was obtained. Regional neck node metastasis was noted in 25.5% and distant metastasis in 24.1%. Local tumor control was found to be a very important factor in survival: 70.2% survival in patients with local control and 28.7% without. The authors conclude that a combined radical surgery and postoperative radiation would improve the prognosis of these patients with major salivary gland tumors.
