When pharmacological treatments are inadequate, facial nerve paralysis from various etiologies, including Bell\'s palsy, Hunt syndrome, and trauma, often requires surgical intervention. Facial nerve decompression surgery aims to relieve nerve compression and restore function, with preserving hearing function, especially in pediatric cases, being crucial. Conventional methods, like the transmastoid approach, risk affecting auditory function due to ossicle manipulation. Herein, we describe the case of a 12-year-old boy with left facial palsy diagnosed with zoster sine herpete (ZSH) syndrome. Despite medical treatment, the patient\'s condition did not improve, prompting facial nerve decompression surgery. Employing the intact transmastoid ossicle (ITO) swaying technique, we minimized ossicular manipulation, preserving auditory function while effectively achieving facial nerve decompression. The patient demonstrated improvement postoperatively in auditory and facial nerve functions. Furthermore, audiometric assessments demonstrated no substantial deterioration in hearing thresholds, and the facial nerve function improved from Grade V to Grade II on the House-Brackmann scale. The ITO technique provides a less invasive alternative compared to conventional approaches, lowering the chance of the ossicular chain and the risk of postoperative hearing loss. This case highlights the significance of customized surgical approaches in pediatric facial nerve decompression surgery, resulting in improved patient outcomes. Further research is required to validate the efficacy and safety of this method across various clinical contexts.

Objective:To summarize and analyze the effect of facial nerve decompression surgery for the treatment of Bell\'s palsy and Hunt syndrome. Methods:The clinical data of 65 patients with facial nerve palsy who underwent facial nerve decompression in our center from October 2015 to October 2022 were retrospectively analyzed, including 54 patients with Bell\'s palsy and 11 patients with Hunter syndrome. The degree of facial paralysis（HB grade） was evaluated before surgery, and ENoG, pure tone audiometry, temporal bone CT and other examinations were completed. All patients had facial palsy with HB grade V or above after conservative treatment for at least 1 month, and ENoG decreased by more than 90%. All patients underwent facial nerve decompression surgery through the transmastoid approach within 3 months after onset of symptoms. The recovery effect of facial nerve function after surgery in patients with Bell\'s palsy and Hunter syndrome was summarized and analyzed. In addition, 15 cases in group A（operated within 30-60 days after onset） and 50 cases in group B（operated within 61-90 days after onset） were grouped according to the course of the disease（the interval between onset of symptoms and surgery） to explore the effect of surgical timing on postoperative effect. Results:There was no significant difference between the two groups of patients with Chi-square test（P=0.54） in 42 patients（77.8%, 42/54） with Bell\'s palsy and 7 patients（63.6%, 7/11） in patients with Hunter syndrome who recovered to grade Ⅰ-Ⅱ. According to the course of the disease, 10 cases（66.7%, 10/15） in group A recovered to grade Ⅰ-Ⅱ after surgery. In group B, 39 patients（78.0%, 39/50） recovered to grade Ⅰ-Ⅱ after surgery, and there was no statistically significant difference between the two groups by Chi-square test（P=0.58）. Conclusion:Patients with Bell\'s palsy and Hunter syndrome can achieve good results after facial nerve decompression within 3 months of onset, and there is no significant difference in the surgical effect between the two types of patients.

Idiopathic bilateral facial nerve palsy is a rare condition and presents a diagnostic and prognostic challenge. Specifically, when bilateral nerves are damaged, it is difficult to predict the prognosis. We showcase the usefulness of contrast-enhanced magnetic resonance imaging (MRI) by providing information about localization and severity of degeneration of facial nerve. A 70-year-old Japanese man presented with bilateral simultaneous facial nerve palsy of House-Brackmann Grade VI on both sides. Contrast-enhanced MRI revealed bilateral intensity enhancement of intratemporal facial nerves. The signal intensity was higher on the left side than on the right side. Facial nerve decompression was performed on the left side. The left facial nerve palsy was finally improved eight months after the onset, while the right side was improved just under two months after the onset. Contrast-enhanced MRI for facial nerve palsy can provide valuable information for the evaluation of damaged facial nerves. In our patient\'s case, it was useful as a prognostic predictor of bilateral facial nerve palsy.

OBJECTIVE: To evaluate and compare the long-term results of patients who underwent facial nerve decompression surgery with either transmastoid-supralabyrinthine (TMSL) or combined transmastoid- middle cranial fossa (MCF) approach for traumatic facial nerve paralysis.
METHODS: This is a single-center retrospective case-control study. The medical records of traumatic facial paralysis patients with House Brackmann (HB) Grade 6 who underwent facial nerve decompression surgery at via either TMSL or MCF approach between January 2011 and December 2017 were reviewed. The patients who had otic capsule involvement and total sensorineural hearing loss, therefore underwent translabyrinthine facial nerve decompression, and the patients follow-up period has not yet reached four years were excluded from the study. Postoperative HB score and hearing status were compared.
RESULTS: Eleven patients were operated with MCF approach (group 1), while 9 patients with TMSL approach (group 2). Average age of patients was 20.04 + 15.2 (range:4-47) years. Three (15 %) patients were female, while 17 (85 %) was male. Geniculate ganglion (90 %) was the most affected segment of the facial nerve. Facial nerve edema was observed in all cases, while intraneural hematoma were encountered in 4 (20 %) cases. Statistically significant improvement in median HB scores were reached in both groups, and no significant difference was observed in post-operative HB scores between both techniques. No significant difference in median AC 0,5-4 khZ and BC 0,5-3 kHz thresholds was observed between both techniques.
CONCLUSIONS: Even middle fossa approach is the best surgical technique to explore geniculate ganglion and labyrinthine segment of facial nerve, the functional results of transmastoid supralabrynthine approach, which is not needed craniotomy with low complication rate are as successful as middle fossa approach in selected patients.

UNASSIGNED: To determine the frequency-specific benefits of ossicular chain preservation compared to performing disarticulations and reconstructions in transmastoid facial nerve decompression surgery in patients with an intact ossicular chain.
UNASSIGNED: A retrospective chart review (January 2007 and June 2018) of patients undergoing transmastoid facial nerve decompression on the intact middle ear for severe facial palsy at a tertiary referral center. Surgery was performed with ossicular chain disarticulation on an as-needed basis using either ossicular chain preservation (without ossicular disarticulation), incudostapedial separation, or incus disarticulation technique. Hearing outcomes were assessed.
UNASSIGNED: The 108 patients were included in this study. Among these, 89 patients underwent ossicular chain preservation, 5 underwent incudostapedial separation and 14 underwent incus repositioning. The proportion of patients with a change in the 4-frequency air conduction pure-tone average of less than 10 dB was 91%, 60%, and 50%, respectively, for the three surgical techniques; these were significantly different (Fisher\'s exact test, p < .001). Frequency-specific analysis showed that air conduction was significantly better following the ossicular chain preservation technique compared with the incus repositioning technique at stimulation frequencies lower than 250 Hz and higher than 2000 Hz, and compared with the incudostapedial separation technique at 4000 Hz. Analysis of biometric measures determined on CT images suggested that the feasibility of the ossicular chain preservation technique correlates with incus body thickness on coronal CT images.
UNASSIGNED: Ossicular chain preservation is an effective approach for hearing preservation in transmastoid facial nerve decompression or similar surgical procedures.

Facial nerve paralysis is one of the most common symptom an otology surgeon comes across. Aim of this article is to review the literature, to study the important causes, pathogenesis and to know the common sites of involvement in different types of facial paralysis with importance of imaging in identifying the site of lesion and role of surgery and outcome of conservative management in case of infranuclear facial paralysis. This is a prospective study of 23 cases of infranuclear facial paralysis in case of post-head injury, post-mastoidectomy and otitis media. Facial paralysis due to post head injury is more common in adult males due to their active life and road traffic accident is the main cause. Longitudinal Fracture of temporal bone is a common fracture and it accounts for more number of facial paralysis. Decompression of the Facial nerve has beneficial effects. HRCT delineates the status of facial nerve in intratemporal part. Cholesteatoma and granulation tissue both play equal causative role for facial paralysis in otitis media.

OBJECTIVE: Facial nerve decompression surgery is performed on patients with immediate, complete traumatic facial palsy. However, the clinical advantage of the surgical treatment has weak evidence because of lack of control groups in previous studies. Therefore, this study compared facial function outcomes between the patients who underwent surgery and those who did not. Furthermore, in cases of bilateral traumatic facial palsy, the outcomes of the surgical and nonsurgical sides were also discussed.
METHODS: A retrospective medical chart review of immediate and severe (House-Brackman [HB] grade V and VI) traumatic facial palsy was conducted. Twenty-five ears from the surgical group and eight ears from the conservative treatment group were enrolled. Among the patients, three with immediate and severe bilateral facial palsy underwent unilateral surgery.
RESULTS: The average HB grade after 1-year follow-up was 1.7 in the surgical group and 1.5 in the nonsurgical group. Four patients who have definite facial canal disruption in the imaging study have recovered to HB grades I-III without surgical intervention. In patients with bilateral facial palsy, the nonsurgical side showed the same or better facial functions than the surgical side.
CONCLUSIONS: Compared with nonsurgical conservative treatment, facial nerve decompression surgery did not show superior outcomes in immediate HB grade V-VI traumatic facial palsy. The clinical advantage of facial nerve decompression is questionable and should be re-evaluated in a prospectively designed study.

BACKGROUND: To evaluate patients with middle ear cholesteatoma presenting with facial palsy (FP).
METHODS: A total of 14 subjects (10 males and 4 females), with a mean age of 42.5 years, were included in our study. The majority of patients presented with incomplete FP (House-Brackmann HB II-IV, 11 cases) and the remaining 3 patients had complete facial paralysis (HB V-VI). A canal wall down mastoidectomy was performed in all the patients, followed by partial facial nerve decompression.
RESULTS: At the one-year follow-up, eleven (78.5%) patients demonstrated satisfactory recovery to HB I-II. Facial function recovered to HB grade I-II in 9 (100%) patients who were surgically treated within one month, and in 2 (40%) patients who underwent surgery after one month. The tympanic segment of facial nerve was the most common site of involvement (8 patients). The multiple regression analysis showed that a higher preoperative HB grade combined with a gradual than sudden onset of FP more likely resulted in worse postoperative HB grade.
CONCLUSIONS: Early surgical removal of cholesteatoma associated with FP is more likely to result in good facial nerve recovery (78.5% of cases), when it is performed within one month from the onset of FP. According to the literature, the tympanic segment of the facial nerve was more frequently damaged (77.7%), followed by the mastoid segment (22.9%), labyrinthine segment (11.1%), and geniculate ganglion (11.1%). Labyrinthine fistula, mainly of the lateral semicircular canal, can be expected in cases of facial nerve dehiscence. The canal wall down mastoidectomy combined with partial decompression surgery was the most preferred surgical treatment for the FP secondary to cholesteatoma.

OBJECTIVE: We aimed to present the management of the patients with necrotizing otitis externa (NOE) and its comorbidities in early and long-term follow-up.
METHODS: Between 2011 and 2022, 30 patients with the diagnose of NEO, who had cortical bone erosion or trabecular demineralization in temporal bone computed tomography and administered at least 6-week antimicrobial therapy were included in the study. Clinical, laboratory and imaging findings of patients, and comorbidities during follow-up were analysed. NOE extending further from the petro-occipital fissure on magnetic resonance imaging was accepted as medial skull base (MSB) involvement.
RESULTS: 30 patients, (8 women, 22 men, mean age 66.2 ± 1.7), with NOE were followed 36.4 ± 29.6 months. The mortality rate was 23.33% and the mean survival time was 12.37 ± 11.35 months. Repeated cultures reveal a new or second pathogen in 5 patients (20%). Severe and profound sensorineural hearing loss (SNHL) were observed in 4 and 12 patients, respectively. Labyrinthitis ossificans emerged in 3 of 6 surviving patients with profound SNHL during follow-up. Chronic disease anemia (CDA) (66.66%), cerebrovascular disease (CVD) (43.33%), chronic renal failure (CRF) (30%), and retinopathy (26.66%) were the most frequent comorbidities in patients with NOE. Cranial nerve paralysis (CNP) (P < 0.001), SNHL (P < 0.04), CDA (P < 0.005), and mortality (P < 0.022) were significantly associated with the presence of MSB involvement.
CONCLUSIONS: NOE is a disease that requires long-term follow-up, causes severe morbidity, and has a high mortality rate. MSB involvement is associated with CNP, SNHL and labyrinthitis ossificans. Moreover, CDA, CVD, CRF and retinopathy are the most common comorbitidies needed to be managed.
