This Week in Otolaryngology — Sep 10, 2026

Welcome to This Week in Otolaryngology. This week we're covering 10 notable papers spanning facial nerve prognosis and surgery, hearing and balance rehabilitation, head and neck cancer decision-making, and the epidemiology of smell loss. Let's dive in.

We start with the facial nerve, where two papers ask when to escalate from observation to testing and then to surgery. In JAMA Otolaryngology-Head and Neck Surgery, Chang and colleagues report a single-centre cohort of more than three thousand five hundred adults with acute Bell palsy who underwent standardized four-branch electroneuronography and needle electromyography at about two weeks after onset [1]. Among the roughly nineteen hundred patients with complete six-month follow-up, just over half had incomplete recovery, defined as a final House-Brackmann grade of two or worse. A degeneration index of ninety percent or more in any branch raised the odds of incomplete recovery roughly fivefold, complete denervation on electromyography did much the same, and when both findings co-occurred in the same muscle the odds of incomplete recovery rose roughly eightfold. The clinically important part is the subgroup analysis: current guidelines steer electrodiagnostic testing towards patients with complete or near-complete paralysis, but in patients presenting at grade four, moderate paralysis, both markers still roughly tripled the odds of incomplete recovery. Adding the degeneration index to the initial House-Brackmann grade improved discrimination by about six points, to just under 0.80. That is a real but modest gain, in a cohort where nearly half of patients did not complete follow-up, and the authors themselves call for prospective validation before widening indications. Still, if you counsel Bell palsy patients, this argues that grade four is not automatically a group in whom testing adds nothing.

At the other end of the facial nerve spectrum, Otology and Neurotology publishes a retrospective case series from Pollaers and colleagues on elective facial nerve decompression for recurrent inflammatory palsy [2]. Seventeen nerves were decompressed in patients with three or more ipsilateral episodes from recurrent idiopathic Bell palsy or Melkersson-Rosenthal syndrome, and sixteen of those seventeen nerves derived benefit, with the time spent with facial weakness falling from roughly eight weeks per year to only a few days per year. This is a small uncontrolled series from a quaternary centre, so selection matters enormously, but it gives you something concrete to offer the patient who keeps returning with the same side dropping.

Moving to hearing rehabilitation, two papers push on the boundaries of cochlear implant candidacy. In The Laryngoscope, Patel and colleagues report a five-centre retrospective cohort of 68 adults implanted after prolonged unilateral severe to profound hearing loss, with a median duration of deafness of seventeen years [3]. Just over half of patients gained at least twenty percentage points in word recognition, about a third gained fifty points or more, and the mean improvement was around 28 percentage points. Daily device use averaged more than eight hours in the first year and remained around seven hours beyond a year, which tells you these were not drawer devices. Critically, on multivariable analysis the duration of deafness did not predict post-implant word recognition. The authors' conclusion is that duration of auditory deprivation alone should not be an absolute exclusion criterion, and candidacy should be individualized. Alongside that, Otology and Neurotology publishes a systematic review from Paouris and colleagues on labyrinthectomy combined with cochlear implantation in Meniere disease, pooling eight studies and 123 implanted ears, mostly case series [4]. Reporting was heterogeneous across audiological measures, but most studies showed measurable auditory benefit, with low to mild residual dizziness handicap and low to mild residual tinnitus burden. In the patient with disabling vertigo and non-serviceable hearing, ablating the labyrinth and implanting the same ear, either simultaneously or sequentially, looks like a defensible option in carefully selected cases, though the evidence base remains low-level.

Staying in the ear, one paper this week directly challenges a routine habit. Chen and colleagues, also in Otology and Neurotology, present a systematic review and meta-analysis of pressure dressings after otologic surgery, covering eleven studies and more than thirteen hundred operated ears [5]. The odds of haematoma or seroma did not differ between ears that received a pressure dressing and those that did not. What did differ was harm: dressing-related headache occurred in about a third of dressed patients versus roughly one in eleven undressed, skin erythema occurred in about a fifth of dressed ears versus well under one percent without, and auricular bruising was also more common with dressing. The conclusion is straightforward — with adequate haemostasis, routine pressure dressing after otologic surgery may simply be unnecessary morbidity. That is a low-cost change to your postoperative order set.

Two papers address the dizzy and the refractory ear diagnostically. Booth and colleagues, in Otology and Neurotology, meta-analyzed vestibular rehabilitation in vestibular migraine across seven studies and 272 adults [6]. The pooled reduction in the Dizziness Handicap Inventory was roughly 24 points, which is clinically meaningful, and every included study showed improvement. Two caveats deserve airtime: improvements in the Activity-Specific Balance Confidence scale did not reach clinically significant thresholds, so this is about handicap rather than measured balance confidence, and heterogeneity was extremely high with funnel plot asymmetry suggesting small-study effects. Vestibular rehabilitation remains a reasonable adjunct in vestibular migraine, but the effect size should be quoted cautiously. Then Oi and colleagues report a small single-centre study on distinguishing otitis media with ANCA-associated vasculitis from ordinary refractory effusion in elderly patients [7]. Comparing 21 patients with the effusion-type presentation of vasculitic otitis media against nine with genuinely refractory effusion, a tympanic membrane scoring system was higher in the vasculitis group, driven by vascular dilatation and posterior wall swelling, and while three-frequency pure-tone averages did not separate the groups, low-frequency bone conduction thresholds did. Combining the membrane score with the 500 hertz bone conduction threshold gave an area under the curve of about 0.95 with perfect sensitivity in this small sample. With only thirty patients total this is a signal, not a validated rule, but the practical message is that an elderly patient with refractory effusion, an inflamed vascular-looking drum and a low-frequency sensorineural component deserves ANCA testing.

In head and neck oncology, two papers deal with choosing and surviving treatment. The American Journal of Otolaryngology reports a prospective randomized pilot trial from Ye and colleagues comparing transoral laser microsurgery against definitive radiotherapy with or without concurrent chemotherapy in early T-stage hypopharyngeal cancer [8]. Only seventeen patients were randomized, so treat this as hypothesis-generating. Functional laryngeal preservation at one year was 100 percent in the radiation-based arm versus about 44 percent in the surgical arm, and voice quality measures favoured radiation. The mechanism the authors propose is instructive: more than half of the surgical patients needed adjuvant chemoradiation for adverse pathology, so they absorbed the cumulative morbidity of trimodality therapy. Disease-free survival showed only a non-significant trend favouring radiation, and oncological control appeared broadly comparable. Complementing that, Otolaryngology-Head and Neck Surgery publishes a systematic review by Metpally and colleagues on frailty and recovery after microvascular free flap reconstruction, covering eleven studies [9]. Frailty was consistently associated with more medical complications, longer hospital stay, higher likelihood of non-home discharge, impaired swallowing recovery and longer enteral nutrition dependence. Associations with surgical complications and short-term mortality were inconsistent, and measures incorporating nutrition or sarcopenia outperformed frailty indices alone. Use frailty screening to shape counselling and discharge planning, not to deny surgery.

Finally, on olfaction, JAMA Otolaryngology-Head and Neck Surgery reports a survey study from the Agricultural Health Study in which Song and colleagues examined high pesticide exposure events in more than two thousand five hundred farmers [10]. Self-reported olfactory dysfunction was about a third more common among farmers with a history of high-exposure events, around 21 percent versus 15 percent. But measured performance on the twelve-item Brief Smell Identification Test showed no association at all, and neither did perceived difficulty with the test. The honest reading is that exposure tracked subjective complaint but not objective identification — a reminder that self-report and psychophysical testing are measuring different things, and that epidemiologic work on smell needs both.

If you only have time for one paper this week, make it the JAMA Otolaryngology cohort on electrodiagnostic testing in Bell palsy [1]. It is the largest dataset of its kind and it directly questions where we currently draw the line for testing, with immediate implications for how you prognosticate for the patient sitting in front of you.

Here are the key takeaways from this week in Otolaryngology. First, in Bell palsy, severe degeneration on electroneuronography and complete denervation predict incomplete recovery even in moderate, grade four paralysis, so consider testing a wider group while awaiting prospective validation. Second, recurrent inflammatory facial palsy after three or more episodes may respond well to targeted decompression in selected patients. Third, prolonged unilateral deafness, even beyond a decade, should not by itself exclude a patient from cochlear implantation, and labyrinthectomy with implantation is an option in end-stage Meniere disease. Fourth, routine pressure dressings after otologic surgery do not reduce haematoma but do increase headache and skin complications. And fifth, in early hypopharyngeal cancer, a surgery-first pathway frequently ends in trimodality therapy, which in this small randomized pilot came at a cost to laryngeal function.
