“…6 And the study by Schmidt et al reported that the auriculotemporal nerve produced numbness, pain, or both in the temporomandibular joint region. 13,16 Rather surprisingly, we found that periotic pain could improve significantly or fully resolve within 4.07 months compared to that of numbness, which occurred within 7.36 months (P < 0.01). This suggested that periotic pain was functionally more resilient, relative to other sensory dysfunctions, especially tactile hypoaesthesia/numbness.…”

“…Ryan and Fee found that the impairment of the great auricular nerve, demonstrated by the results of the sensory testing, was able to induce periotic sensory symptoms, particularly numbness, during parotidectomy . And the study by Schmidt et al reported that the auriculotemporal nerve produced numbness, pain, or both in the temporomandibular joint region …”

“…To our knowledge, it is the first study to evaluate the recovery from periotic sensory disturbance and discomfort after tympanoplasty via a postauricular approach. For the intriguing result, it was explained that periotic sensory dysfunction was not a disease but rather a symptom and sign caused by the multiple cutaneous nerves trunk in the auricular area with overlapping distributions . Huang and Sengupta et al explained that the recovery of pain was sooner than numbness because the sense of pain mainly originated from smaller diameter unmyelinated C fibers, while the sense of numbness was involved in A‐delta fibers .…”

Objectives/Hypothesis To assess the somatosensory dysfunction of the auricle and periotic skin in patients undergoing otitis media surgery. Study Design Retrospective study. Methods Symptoms of periotic somatosensory function after surgery were investigated in 100 patients (42 males, 58 females, mean age 41.39 years) who underwent otitis media surgery. Questionnaires on periotic somatosensory disturbance were answered after surgery at least over 1 year postoperatively. Results Of 100 tympanoplasties, all patients were completed within a postauricular approach. The highest incidence rates of periotic sensory disturbance were found in the postauricular region (75%), followed by the auricular region (20.83%); lower rates were found in the preauricular region (2.08%) and the earlobe (2.08%). Periotic somatosensory dysfunction occurred in 48 patients (48%). The most prevalent somatosensory abnormality was tactile hypoaesthesia/numbness, evident in 28% of the patients; more remarkable, inferior postauricular region. Periotic pain was reported by 21% of the cases, mostly located in the upper auricle. Compared to the recovery time of tactile hypoaesthesia (7.36 months), patients' periotic somatosensory pain improved significantly within 4.07 months, which has obvious statistical significance (P < 0.01). Conclusion The likelihood of periotic cutaneous sensory dysfunction should be emphasized to patients undergoing otitis media surgery via postauricular approaches, which occurred in nearly half of patients; the majority recovered within 1 year. Furthermore, the postauricular region is the most vulnerable location to sensory disturbance, followed by the auricular region. Functionally, periotic somatosensory pain was more easily resilient, relative to tactile hypoaesthesia/numbness. Level of Evidence 4 Laryngoscope, 129:454–458, 2019

“…The middle of the tragus (Point T) was defined as a reference point. Next, the branching point of the STb (Point S) of the ATN and the Pb (Point P) of the ATN were identified by using our previous studies as references (Iwanaga et al, ); the vertical distance between point S to point T ranged from 6.2 to 25.7 mm (mean; 15.9 ± 6.7 mm), horizontal distance between point S to point T ranged from 3.5 to 11.9 mm (mean; 7.5 ± 2.5 mm), the vertical distance between point P to point T ranged from 1.8 to 16.2 mm (mean; 8.3 ± 4.7 mm), and the horizontal distance between point P to point T ranged from 3.0 to 12.6 mm (mean; 7.9 ± 3.1 mm). The average length of the longest STb of the ATN was longer than the average distance from Point T to the lateral canthus.…”

A novel treatment for keratitis sicca (Dry eye): Anatomical feasibility study

Chronic dry eye (keratitis sicca) is a significant problem that in certain populations can result in corneal desiccation and the potential for blindness. Therefore, novel treatments for such disorders might decrease patient morbidity. The present study aimed to investigate a potential treatment for chronic dry eye via a cadaveric feasibility study. On 10 cadaveric sides, the parotid gland branch of the auriculotemporal nerve (ATN) was identified and anastomosed to an anterior superficial temporal branch (STb) of this same nerve. The STb was then transposed anteriorly and sutured to the lacrimal gland. The parotid branch of the ATN was easily identified on all sides. The STb of the ATN was easily identified and mobilized on all sides. This latter nerve had adequate length to be moved to the ipsilateral lacrimal gland on all sides. Rerouting parotid gland secretomotor fibers to the superficial branch of the ATN and then moving this branch to the lacrimal gland is a feasible surgical maneuver based on our cadaveric study. Clinical studies are now necessary to show utility of this procedure in patients with chronic dry eye. Clin. Anat. 30:839-843, 2017. © 2017Wiley Periodicals, Inc.

Anatomical study of the supraorbital and supratrochlear nerves: A new classification and application to understanding some migraine headaches

et al. 2019

The frontal nerve is the largest branch of the ophthalmic nerve. This nerve gives rise to two terminal branches, the supraorbital (SON) and supratrochlear nerves (STN). To the best of our knowledge, there are no reports describing the detailed proximal course of these nerves while inside the orbit. Therefore, the goal of this study was to clarify the anatomy of the SON and STN inside and at their exit from the orbit. Twenty sides from ten fresh‐frozen cadavers were used in this study. Intra and extra orbital dissections were performed to observe the course of the SON and STN. Additionally, measurements of the nerves were made at these locations. The course of the SON and STN inside the orbit was classified into three groups depending on the STN branching pattern from the SON. The group without any branch from the SON and STN inside the orbit was the most common. The exit points of these nerves were via the supraorbital notch, foramen, or neither a notch nor foramen. A distinct fibrous band was consistently found tethering the nerve except in specimens with nerves traversing a bony foramen. The mean diameters of the SON and STN were 1.3 ± 0.2 and 0.7 ± 0.1 mm, respectively. The results of this study further our knowledge of the course and morphology of the SON and STN and might be useful for better understanding and potentially treating some forms of migraine headache due to SON or STN compression/entrapment.
